LIGHT TUBES, LIGHT FIXTURES, AND LIGHT BODIES

TECHNICAL FIELD

The present disclosure relates to the field of lighting technology, and in particular, to a light tube, a light fixture, and a light body.

BACKGROUND

In many homes, entertainment and leisure, dining, or shopping occasions, light fixtures are increasingly used as decorative amenities that create ambiance and beautify the environment. In order to meet the increasingly diverse decorative needs and facilitate customized decorations, a wide range of ambient lighting has been introduced in the market to users to choose appropriate styles of ambient lighting for different decorative purposes.

Traditional light fixtures are equipped with light strips in the light tubes with a light homogenizing function, making the dispersed light more uniform. However, the light strip emits light from only one side, and the back of the light-emitting surface does not emit light. If it is necessary to make the entire circumference of the light tube emit light, at least two light strips need to be mounted, and the back sides of the two light strips need to be oppositely disposed with the light-emitting surfaces radially facing outward, which greatly increases the production difficulty and cost. In addition, with the development of industrial design, the monotonous styling of traditional light fixtures no longer meets the aesthetic requirements of consumers.

Therefore, the present disclosure provides a light tube, a light fixture, and a light body capable of presenting various lighting effects and different stylings, achieving a wide range of applicable scenarios.

The light-transmitting tube 10 refers to a tubular structural member that allows light to pass through. The light-transmitting tube 10 may include a hollow hole. In some embodiments, the light-transmitting tube 10 may include at least one of a silicone tube, a glass tube, or a plastic tube. The plastic tube may include an acrylic tube, a polycarbonate (PC) tube, or a polyvinyl chloride (PVC) tube, etc. In some embodiments, the light-transmitting tube 10 may be a transparent tube with high light transmittance to show a crystal clear effect and make the light tube more delicate.

In some embodiments, as illustrated in FIG. 4 and FIG. 5, the tube member 1 may include only the light-transmitting tube 10 and may not include the one or more inner layers.

In some embodiments, an outer wall of the light-transmitting tube 10 may be provided with a coated layer 12, an outer refraction layer 16, or an outer diffuse reflection layer 17.

The coated layer 12 refers to a surface structure covering the light-transmitting tube 10. The coated layer 12 may be made of a wear-resistant and corrosion-resistant material, such as an anodized film, a chrome-plated film, etc. For example, as illustrated in FIG. 3, FIG. 4, and FIG. 7, the outer wall of the light-transmitting tube 10 may be provided with the coated layer 12.

The outer refraction layer 16 is a surface structure capable of refracting light outside the light-transmitting tube 10. In some embodiments, the outer refraction layer 16 may include a plurality of second refraction surfaces. The plurality of second refraction surfaces may be distributed on the outer wall of the light-transmitting tube 10. Structures of the second refraction surfaces may be the same as those of first refraction surfaces, as described below for the first refraction surfaces. In some embodiments, as illustrated in FIG. 8, the outer refraction layer 16 may be disposed on the outer wall of the light-transmitting tube 10 and integrated with the light-transmitting tube 10.

The outer diffuse reflection layer 17 is a surface structure capable of performing diffuse reflection on light outside the light-transmitting tube 10. In some embodiments, as illustrated in FIG. 5, the outer diffuse reflection layer 17 may be disposed on the outer wall of the light-transmitting tube 10.

In some embodiments, the outer diffuse reflection layer 17 may include a second coating layer or a second micro-rough layer.

The second coating layer refers to a surface sprayed with a diffuse reflective coating outside the light-transmitting tube 10. Descriptions regarding the diffuse reflective coating may be found in the related descriptions below.

The second micro-rough layer refers to a rough surface disposed outside the light-transmitting tube 10. Formation of the second micro-rough layer may be similar to formation of a first micro-rough layer, which may be found in the related descriptions below.

By setting the coated layer 12 outside the light-transmitting tube 10, the corrosion resistance of the tube member 1 can be improved, and the tube member 1 can be prevented from being corroded by chemical substances, thereby extending the service life of the tube member 1. Meanwhile, the coated layer 12 can increase the abrasion resistance of the tube member 1, and can also make the surface of the tube member 1 more beautiful and flatter, enhancing the visual effect of the tube member 1. The outer diffuse reflection layer 17 realizes uniform diffuse reflection of light through the second coating layer or the second micro-rough layer, thereby reducing glare and avoiding harm to eyes. The outer refraction layer 16 can realize multi-directional refractions through the plurality of second refraction surfaces for multiple times, thereby forming brilliant and colorful light.

In some embodiments, the light tube may further include a heat-absorbing layer.

The heat-absorbing layer refers to a layer structure for absorbing heat. In some embodiments, the heat-absorbing layer may be made of a material with good thermal conductivity, such as an aluminum plate, an aluminum foil, silica gel, or quartz glass, etc.

In some embodiments, the heat-absorbing layer may be disposed on an inner wall of the light-transmitting tube 10.

Heat is released due to illumination performed by the at least one flexible filament 2 when energized. Arranging the heat-absorbing layer on the inner wall of the light-transmitting tube 10 may prevent a light-emitting device from overheating and affecting the service life, and prevent safety problems.

In some embodiments, the light tube may further include a waterproof layer.

The waterproof layer refers to a layer structure that may act as a waterproof layer. In some embodiments, the waterproof layer may be made of a material with good waterproofing performance, such as polyvinyl chloride, a fluorinated polymer, or polycarbonate, etc.

In some embodiments, the waterproof layer may be disposed on the outer wall of the light-transmitting tube 10.

By placing the waterproof layer on the outer wall of the light-transmitting tube 10, the light tube may also be used underwater, extending the application scenarios of the light tube.

The one or more inner layers refer to structural layers disposed in the light-transmitting tube 10. In some embodiments, the one or more inner layers may be disposed on the inner wall of the light-transmitting tube 10 and capable of modifying a light emission effect of the at least one flexible filament 2. Light emitted from the at least one flexible filament 2 may be projected onto the light-transmitting tube 10 through the one or more inner layers and then transmitted outward through the light-transmitting tube 10. In this case, the one or more inner layers may diffusely reflect or homogenize the light passing through the one or more inner layers, making the light emitted from the at least one flexible filament 2 more uniform, enhancing the display effect, reducing glare, and creating a diffuse reflection light source to avoid causing harm to eyes.

In some embodiments, the one or more inner layers may include at least one of the diffusion tube 11, the inner refraction layer 15, or the inner diffuse reflection layer 13. For example, as illustrated in FIG. 2 and FIG. 3, the one or more inner layers may include the diffusion tube 11. As illustrated in FIG. 6 and FIG. 7, the one or more inner layers may include the inner diffuse reflection layer 13. As illustrated in FIG. 8, the one or more inner layers may include the inner refraction layer 15

In some embodiments, the one or more inner layers may include two or more inner layers. For example, the one or more inner layers may include one of the diffusion tube 11, the inner refraction layer 15, or the inner diffuse reflection layer 13, or any combination thereof.

The diffusion tube 11 refers to a tubular structural member that scatters light. A material of the diffusion tube 11 has certain transparency and scattering performance, so that the light passing through the diffusion tube 11 is softer and more uniform. In some embodiments, as illustrated in FIG. 2 and FIG. 3, the one or more inner layers may be the diffusion tube 11, and the tube member 1 may include the light-transmitting tube 10 and the diffusion tube 11. For example, as illustrated in FIG. 2, the diffusion tube 11 may be disposed on the inner wall of the light-transmitting tube 10.

In some embodiments, the diffusion tube 11 may be sleeved within the light-transmitting tube 10. For example, as illustrated in FIG. 2 and FIG. 9, the diffusion tube 11 may be sleeved within the light-transmitting tube 10 to form the tube member 1.

In some embodiments, the diffusion tube 11 may include at least one of a colored plastic tube, a fluorescent plastic tube, a frosted plastic tube, or a heat-shrinkable sleeve. The heat-shrinkable sleeve may be a colored heat-shrinkable plastic tube with light transmittance and diffuse reflection performance.

The light-transmitting tube 10 and the diffusion tube 11 may be made of different materials, so that the light tube can present different lighting effects through combination of different materials, thereby realizing the lighting needs for multiple scenarios.

In some embodiments, the inner wall of the light-transmitting tube 10 may be a non-smooth surface. In some embodiments, the outer wall of the diffusion tube 11 may be a non-smooth surface. In some embodiments, both the inner wall of the light-transmitting tube 10 and the outer wall of the diffusion tube 11 may be non-smooth surfaces.

When the diffusion tube 11 penetrates into the light-transmitting tube 10, the outer wall of the diffusion tube 11 may contact with the inner wall of the light-transmitting tube 10. A contact surface may be a non-smooth surface, which may not cause extrusion to form a contact surface as an indentation.

In some embodiments, a wall thickness of the light-transmitting tube 10 may be within a range of 5 mm-20 mm. A hole diameter of the light-transmitting tube 10 may be within a range of 3 mm-10 mm. A wall thickness of the diffusion tube 11 may be within a range of 0.1 mm-3 mm. For example, the wall thickness of the light-transmitting tube 10 may be within a range of 6 mm-8 mm. The hole diameter of the light-transmitting tube 10 may be within a range of 4 mm-6 mm. The wall thickness of the diffusion tube 11 may be within a range of 0.1 mm-1.2 mm. As another example, the wall thickness of the light-transmitting tube 10 may be within a range of 18 mm-20 mm. The hole diameter of the light-transmitting tube 10 may be within a range of 8 mm-10 mm. The wall thickness of the diffusion tube 11 may be within a range of 2.4 mm-3 mm. In some embodiments, the wall thickness of the light-transmitting tube 10, the hole diameter of the light-transmitting tube 10, and the wall thickness of the diffusion tube 11 may also be set to other combinations of ranges, which may be determined based on actual needs.

The hole diameter of the light-transmitting tube 10 refers to a diameter of the inner wall of the light-transmitting tube 10, i.e., a diameter of a hollow hole in the light-transmitting tube 10. It should be understood that the hole diameter of the light-transmitting tube 10 may be greater than an outer diameter of the diffusion tube 11, thereby ensuring that the diffusion tube 11 may be disposed in the hollow hole in an inner side of the light-transmitting tube 10. The outer diameter of the diffusion tube 11 refers to a diameter of the outer wall of the diffusion tube 11.

In some embodiments, the wall thickness of the light-transmitting tube 10 may be greater than or equal to ⅕ of the outer diameter of the light-transmitting tube 10. The outer pipe diameter of the light-transmitting tube 10 refers to a diameter of the outer wall of the light-transmitting tube 10. In some embodiments, the outer diameter of the light-transmitting tube 10 may be determined to be within a range of 13 mm-50 mm based on the wall thickness and the hole diameter of the light-transmitting tube 10. For example, if the outer diameter of the light-transmitting tube 10 is 40 mm, the wall thickness of the light-transmitting tube 10 may be greater than or equal to 8 mm. The above mode of setting the wall thickness of the light-transmitting tube 10 ensures the wall thickness of the light-transmitting tube 10 and reflects the three-dimensional effect between the light-transmitting tube 10 and the diffusion tube 11. In addition, since the wall thickness of the light-transmitting tube 10 is relatively large, the light tube may be more stable and durable.

For example, when the light-transmitting tube 10 is a PC tube and the diffusion tube 11 is a milky-white acrylic tube, the outer diameter of the PC tube may be within a range of 15 mm-25 mm, and the hole diameter of the PC tube may be within a range of 8 mm-10 mm. The outer diameter of the milky-white acrylic tube may be within a range of 6 mm-10 mm, and the hole diameter of the milky-white acrylic tube may be within a range of 4 mm-8 mm.

In some embodiments, as illustrated in FIG. 2, a thickness of a gap 20 between the outer wall of the diffusion tube 11 and the inner wall of the light-transmitting tube 10 may be within a range of 0.1 mm-10 mm. The thickness of the gap refers to an average thickness of the gap. By arranging a certain thickness of gap between the outer wall of the diffusion tube 11 and the inner wall of the light-transmitting tube 10, it may be easier for the diffusion tube 11 to penetrate into the light-transmitting tube 10.

In some embodiments, the hole diameter of the diffusion tube 11 may be greater than a diameter of the at least one flexible filament 2, thereby ensuring penetration of the at least one flexible filament 2. For example, the hole diameter of the diffusion tube 11 may be at least 2 mm greater than the diameter of the at least one flexible filament 2. In some embodiments, the diameter of the at least one flexible filament 2 may be within a range of 1.5 mm-3 mm.

The inner refraction layer 15 refers to a surface structure capable of refracting light inside the light-transmitting tube 10.

The inner diffuse reflection layer 13 refers to a surface structure capable of diffusing light inside the light-transmitting tube 10

In some embodiments, the inner diffuse reflection layer 13 may include a first coating layer or a first micro-rough layer.

The first coating layer refers to a surface sprayed with a diffuse reflection coating inside the light-transmitting tube 10. The diffuse reflection coating refers to a coating capable of scattering light uniformly, such as a white diffuse reflection coating, a diffuse reflection coating for metal particles, etc.

The first micro-rough layer refers to a rough surface disposed in the light-transmitting tube 10. The first micro-rough layer may be formed by a surface roughening treatment. The surface roughening treatment may include a surface treatment by a mechanical technology or a chemical technology for achieving a micro-rough surface structure through mechanical abrasion or chemical etching.

In some embodiments, the inner diffuse reflection layer 13 may be disposed on the inner wall of the light-transmitting tube 10, or on the inner and/or the outer wall of the diffusion tube 11. For example, as illustrated in FIG. 6, when the one or more inner layers include only the inner diffuse reflection layer 13, a diffuse reflection effect may be achieved either by spraying the diffuse reflection coating on the inner wall of the light-transmitting tube 10 or performing the surface roughening treatment on the inner wall of the light-transmitting tube 10.

In some embodiments, the inner refraction layer 15 may include a plurality of first refraction surfaces. The plurality of first refraction surfaces may be distributed on the inner wall of the light-transmitting tube 10. The plurality of first refraction surfaces may include at least one of a refraction plane, a spherical plane, or a curved plane. In some embodiments, the inner refraction layer 15 may be disposed on the inner wall of the light-transmitting tube 10 and integrated with the light-transmitting tube 10. In some embodiments, the plurality of first refraction surfaces may be distributed circumferentially and capable of refracting light emitted from the at least one flexible filament 2 in different directions for multiple times.

The inner diffuse reflection layer 13 achieves uniform diffuse reflection of the light through the first coating layer or the first micro-rough layer, so as to reduce glare and avoid causing harm to the eyes. The inner refraction layer 15 may achieve multi-directional refractions through the plurality of first refraction surfaces, thereby forming the brilliant and colorful light.

The at least one flexible filament 2 refers to an elongated and flexible structural member. A material of the at least one flexible filament 2 may be a metal or an alloy. After the light tube is energized, the at least one flexible filament 2 may emit light. In some embodiments, one or more flexible filaments 2 may be provided.

The one or more flexible filaments 2 may be juxtaposed or spliced to form a longer flexible filament 2 penetrating into the one or more inner layers.

During mounting, the at least one flexible filament 2 may penetrate into the one or more inner layers with an auxiliary means. The auxiliary means may include guiding the at least one flexible filament 2 through a guide tube, making the at least one flexible filament 2 penetrate into the one or more inner layers with a fixture or a clamp, etc.

In some embodiments of the present disclosure, by mounting the light tube on the light holder of different shapes through the sealed end of the tube member, the use requirements of different scenarios can be realized, such as a floor light fixture, a wall light fixture, a table light fixture, etc.

In some embodiments, the light fixture may further include at least one temperature detection element, a communication component, a control component, and at least one power-off device.

The at least one temperature detection element refers to an element for detecting temperature, such as a temperature sensor, etc. The at least one temperature detection element may be configured to detect the temperature of at least one position on the light fixture. In some embodiments, the at least one temperature detection element may be disposed on the light fixture. For example, the at least one temperature detection element may be disposed on or near a power supply of the light fixture. The power supply of the light fixture may include an external power supply, a battery, etc. In some embodiments, the at least one temperature detection element may be connected with the power-off device.

The power-off device refers to a device configured to disconnect a circuit. The power-off device may be set to various circuit breakers, such as an air switch. In some embodiments, the power-off device may be connected with the power supply such as the battery or the external power supply, thereby disconnecting the power supply such as the battery or the external power supply.

The communication component refers to a component for transmitting or receiving information. For example, the communication component may include at least one of a wireless module, a network card module, and a Bluetooth module. In some embodiments, the at least one temperature detection element, the power-off device, and the control component may be in communicating connection based on the communication component.

The control component refers to a component configured to process data related to the light fixture. The control component may be configured as an embedded microprocessor or a simple logic controller, etc.

In some embodiments, the at least one temperature detection element may be distributed at different positions on the light fixture. The distribution positions of the at least one temperature detection element may be related to shape features of the light fixture, wiring features the light fixture, etc.

The shape features of the light fixture are features related to a shape of the light fixture, such as the shape of the light fixture, a size of the light fixture, etc. The shape features of a specific light fixture may be determined, which may be pre-input into the control component.

The wiring features are features related to cable arrangement of the light fixture, such as cable routing, etc. The wiring features of the specific light fixture may be determined, which may be pre-input into the control component.

In some embodiments, the control component may determine nodes based on the shape features and the wiring features of the light fixture, and determine the nodes as distribution positions of the at least one temperature detection element. In some embodiments, the shape features and the wiring features of the light fixture and the nodes may have a correspondence relationship, which may be manually preset. The nodes may include junctions of the cable and turning points of the shape of the light fixture. The junctions of the cable refer to junctions of electrical connections between different structures of the light fixture, e.g., junctions of series and/or parallel connections of the plurality of LED chips 22, junctions of lights and a switch 92, etc. The turning points of the shape of the light fixture refer to a collection of turning points of the light fixture. For example, turning points of a triangular light fixture may be vertices of a triangle, and turning points of a wavy light fixture may be inflection points of waves.

In some embodiments, the shape features of the light fixture may further include a radian distribution feature of the filament.

The radian distribution feature of the filament refers to a feature related to filament bending. For example, if the filament is bent along a filament path, a radian distribution at a bent position of the filament may be the radian distribution feature of the filament.

In some embodiments, the radian distribution feature may be obtained by calculating a curvature. For example, the curvature of each bent position of the filament may be calculated, and the obtained curvature of one or more bent positions may be used as the radian distribution feature.

In some embodiments, the at least one temperature detection element may be distributed at the bent positions of the filament. A distribution count of the at least one temperature detection element at each bent position may be determined based on the curvature. In some embodiments, the distribution count of the at least one temperature detection element may be positively related to the curvature. For example, the distribution count may be obtained based on an equation (1) presented below:

$\begin{matrix} Distribution count = curvature \times k, & (1) \end{matrix}$

- wherein k denotes a parameter greater than 1. It should be understood that the greater the curvature, the greater the bending amplitude, and the greater the distribution count of the temperature detection element; and the smaller the curvature, the smaller the bending amplitude, and the smaller the distribution count of the at least one temperature detection element.

A position of a high bending amplitude tends to gather heat and is more prone to failure. The distribution count of the at least one temperature detection element may be determined through the radian distribution feature of the filament, so that more temperature detection elements may be disposed at the positions with the high bending amplitude, which makes it easy to detect the failure in time.

In some embodiments, the control component may be configured to acquire a temperature distribution from the at least one temperature detection element based on an acquisition cycle; and in response to determining of the temperature distribution, determine a faulty power supply based on the temperature distribution, and control the corresponding power-off device to perform a power-off operation.

The temperature distribution refers to a distribution of a temperature of the light fixture. In some embodiments, the temperature distribution may include temperature monitoring points. The temperature monitoring points refer to detection positions of the at least one temperature detection element. The temperature distribution may include at least one temperature monitoring point and a monitoring temperature corresponding to the at least one temperature monitoring point.

The acquisition cycle refers to an interval at which the control component acquires the temperature distribution, such as once every 5 min, once every 10 min, etc. In some embodiments, the acquisition cycle may be determined in various ways. For example, the acquisition cycle may be set manually on demand.

In some embodiments, the light fixture may further include a remote server. The remote server may be configured to process information related to the light fixture. The information related to the light fixture may include light fixture usage time, the acquisition cycle of the control component for obtaining the temperature distribution, etc. In some embodiments, the remote server may be in communicating connection with the control component through the communication component.

In some embodiments, the remote server may be configured to determine the acquisition cycle based on the light fixture usage time, and send the acquisition cycle to the control component through the communication component.

The light fixture usage time refers to a usage duration of the light fixture. The light fixture usage time may be obtained in various ways. For example, a timer may be arranged on the control component, and the light fixture usage time may be obtained through the timer arranged on the control component.

In some embodiments, the acquisition cycle may be positively related to the light fixture usage time. For example, the acquisition cycle may be calculated based on an equation (2) presented below:

- Acquisition cycle=the light fixture usage time×b+basic cycle (2), wherein b denotes a coefficient greater than 1, which may be preset.

By arranging the remote server and determining the acquisition cycle based on the light fixture usage time, the acquisition cycle may be more in line with an actual usage of the light fixture, helping to troubleshoot the faulty power supply in time.

Due to the design requirements of the light fixture, the control component arranged in the light fixture may be small and computational power may be insufficient. Arranging the remote server may process a large amount of information related to the light fixture, thus making the calculated acquisition cycle of the control component more accurate and in line with the actual situation.

In some embodiments, in response to determining of the temperature distribution, the control component may query a power supply corresponding to the temperature distribution in a preset table based on the temperature distribution, and determine the power supply as the faulty power supply. The preset table may include a mapping relationship between the temperature distribution and the power supply. The preset table may be determined during processing of the light fixture. For example, a temperature monitoring point on a cable connected with an external power supply may correspond to the external power supply, and a temperature monitoring point on the cable connected with a storage battery may correspond to the storage battery. It should be understood that two or more power supplies may share a same circuit, and thus one temperature monitoring point may correspond to two or more power supplies.

In some embodiments, the light fixture may further include a fault indication component. The fault indication component refers to a component for issuing a fault indication. For example, the fault indication component may be a faulty light or a user APP, etc.

In some embodiments, the control component may be further configured to control the fault indication component to perform fault indication based on the faulty power supply.

For example, when the fault indication component is the faulty light, the control component may control the faulty light to turn on. As another example, when the fault indication component is the user APP, the control component may send fault information to the user APP for display.

The fault can be responded in time by repairing or replacing the faulty power supply through the fault indication component.

The light fixture may be connected with the external power supply or the storage battery, and high voltage or current of the power supply may easily cause circuit safety issues. By arranging the distributed temperature detection elements, the communication component, the control component, and the at least one power-off device, the power supply with a circuit problem can be determined and responded by performing the power-off operation, thereby avoiding the safety issues and protecting the light fixture. When one power supply fails, the other power supply may work normally, thereby improving the stability of the light fixture. For example, when the storage battery fails and is powered off, the light fixture may operate normally with the external power supply.
