In the illumination device, as the luminescent units are undetachable and the number of the luminescent units also cannot be adjusted, when the lighting environment changes, an illumination device provided with luminescent units of corresponding number may be repurchased. Thus, the illumination device may not be able to adapt to a variety of lighting environments. The present disclosure provides a light source module and an illumination device for solving the above problem. Detailed description will be given below to the light source module and the illumination device with reference to the accompanying drawings.
As illustrated in
The housing 10 may be made from hard materials such as metal and plastics. Subsequently, the housing 10 can be mounted at an area such as the wall surface or the ceiling by various means such as fasteners and screws, so that a target area can be illuminated.
The illumination device 100 may be a tube spotlight, a lamp board, a dome lamp, a ceiling light, a car light or other types of common lamps in the industry. The illumination device 100 can be converted into a lamp of corresponding type by only adaptive adjustment of the shape of the housing 10. No further description will be given here.
No matter the illumination device 100 adopts any one of the tube spotlight, the lamp board, the dome lamp, the ceiling light or the car light, at least one storage bin 11 can be disposed in the housing 10 of the illumination device 100. The storage bin 11 is configured to accommodate the light source module 20. The shape of the storage bin 11 is preset according to the shape of the light source module 20. For instance, when the shape of the light source module 20 is square, the storage bin 11 is also set to be in the shape of a square opening. No further description will be given here.
Taking a lamp board as an example, a plurality of storage bins 11 arranged in an array may be disposed in an area provided with luminous sources in the conventional lamp board, and subsequently, the light source modules 20 are mounted in the storage bins 11.
The number of the storage bins 11 may be adjusted according to the size of the housing 10. For instance, when the illumination device 100 is taken as a car light, a small number of storage bins 11 may be set, so as to ensure that the size of the illumination device 100 will not be too large, and hence the aesthetic property of the car light will not be damaged. Conversely, when the illumination device 100 is taken as a lamp board, a large number of storage bins 11 may be set, so as to ensure the lighting strength of the lamp board.
The arrangement of the storage bins 11 may also be preset according to the lighting requirement of the illumination device 100. For instance, the storage bins may be disposed on the same straight line and may also be respectively disposed on a plurality of straight lines. No further description will be given here.
The number of the light source modules 20 is also preset according to the lighting requirement, as long as the number of the light source modules 20 does not exceed the number of the storage bins 11.
In the example of the present disclosure, the number of the storage bins 11 is set to be 4, and the storage bins 11 are disposed on the same straight line. The number of the light source modules 20 is also 4, and the light source modules 20 are mounted in the storage bins 11 in one-to-one correspondence. Of course, the number of the light source modules 20 may also be set to be other values less than 4. No further description will be given here.
The power supply module includes mains connections (not shown in the figure) extended into the storage bins 11. The mains connection may be electrically connected with the light source module 20 after the light source module 20 is mounted in the storage bin 11, so the light source module 20 can be electrically connected with the power supply module and then acquires required power from the power supply module.
The power connector may adopt plug type and may also adopt contact type, as long as the light source module 20 can be conveniently electrically connected with the power supply module after being mounted in the storage bin 11. No further description will be given here.
The power supply module may be alternating current (AC) and may also be a direct current (DC) battery pack. If the power supply module is AC, the power supply module is embodied as a plug electrically connected with the power connectors in the storage bins 11. If the power supply module is a DC battery pack, the power supply module is embodied as a battery pack detachably mounted on the housing 10 or a battery pack integrated onto the housing 10, electrically connected with the power connectors in the storage bins 11. The battery pack may be a battery pack customized for the illumination device and may also be a battery pack on other tools, e.g., an electric tool.
The power supply module further may include a protection circuit with functions such as overvoltage protection and overcurrent protection and an output management circuit with voltage and current management, etc. No further description will be given here.
In summary, in the illumination device 100 provided by the example of the present disclosure, when the lighting environment changes, the number of the mounted light source modules 20 may be directly adjusted by the disassembly or assembly of the light source modules 20, and an illumination device with luminescent units of corresponding number is not required to be repurchased, so the illumination device can be adapted to a variety of lighting environments,
With reference to
The shape and the size of the light source module 20 may be standardized. For instance, the light source module may be set to be a square with the thickness of less than 10 mm. The shape of the storage bin 11 cooperated with the light source module 20 is also designed to be standardized. Thus, the light source module 20 of this type may be applied in various types of illumination devices, as long as the shape and the size of the storage bin 11 comply with standards,
With reference to
The luminescent component 21 includes a substrate 211 and at least two luminescent units 212 disposed on the substrate 211. The luminescent unit 212 may be a light-emitting diode (LED) light source, an incandescent lamp, a TL light source and other types.
The substrate 211 may be a printed circuit board (PCB) or a flexible circuit board. The shape of the substrate 211 is set according to the shape of the light source module 20. For instance, the substrate may be set to be a rectangular or circular flat sheet. No further description will be given here.
The luminescent units 212 are annularly distributed on the substrate 211, namely all the luminescent units 212 are disposed on a circular ring of the same circle. The luminescent units 212 may be uniformly distributed and may also be unevenly distributed.
The luminescent units 212 include cool color luminescent units and warm color luminescent units. The cool color luminescent unit and the warm color luminescent unit are respectively configured to emit cool-tone white light and warm-tone white light.
Of course, the cool color luminescent unit and the warm color luminescent unit may also be configured to emit cool light and warm light of other colors. No further description will be given here.
The cool color luminescent units and the warm color luminescent units may be set to be alternately arranged one by one (may also be arranged in a half-and-half manner), namely the warm color luminescent units are respectively disposed on both sides of any cool color luminescent unit and the cool color luminescent units are respectively disposed on both sides of any warm color luminescent unit. Of course, the cool color luminescent units and the warm color luminescent units may also be arranged in a half-and-half manner or arranged according to user demands. No further description will be given here.
The luminescent component 21 further includes a drive unit 213 disposed on the substrate 211. The drive unit 213 is electrically connected with the luminescent units 212 and configured to adjust the current provided for the luminescent units 212, so as to ensure the normal operation of the luminescent units 212.
The drive unit 213 includes an external interface 2131 cooperated with the power connector of the power supply module. After the light source module 2.1 is mounted in the storage bin 11, the power connector of the power supply module may be inserted into the external interface 2131, so that the light source module 21 can be electrically connected with the power supply module.
As the drive unit 213 includes the external interface 2131 capable of being adapted with the power supply module, when the number of the light source modules 20 may be adjusted, the number of the light source modules 20 can be rapidly increased, and the electrical connection between the light source module 20 and the power supply module can be created. Meanwhile, the light source module 20 can be rapidly disassembled, and the electrical connection between the light source module 20 and the power supply module can be cut off.
The light distribution component 22 is configured to adjust the illuminated light emitted by the luminescent component 21 and includes an optical element 221 and a mounting part 222. The optical element 221 and the mounting part 222 may be integrally formed or assembled in a split type.
The optical element 221 includes an annular lens or a transparent mask. The annular lens may be made from transparent materials. The transparent mask may be made from materials with flood characteristic or a condensing lens. Whether the annular lens or the transparent mask is specifically adopted may be selected according to the application environment of the illumination device. No further description will be given here.
In the example of the present disclosure, the illumination angle of the illuminated light emitted by the luminescent units 212 is diffused or converged by adjustment of the shape of the optical element 221. For instance, the illumination angle of the illuminated light may be set to be 30°, 60°, 90°, 130° or any other angle. Flow to adjust the shape of the optical element 221 to obtain the preset illumination angle is technology well-known by those skilled in the art. No further description will be given here.
The mounting part 222 is connected with the optical element 221 and the substrate 211 and is specifically configured to fix the optical element 221 above the luminescent unit 212, so as to ensure that the illuminated light emitted by the luminescent unit 212 can only be projected towards the target area after processed by the optical element 221.
In the example of the present disclosure, the optical element 221 is an annular lens, and the mounting part 222 encircles the optical element 221 and can be detachably mounted on the substrate 211 by fasteners, screws or other means, so that the optical element 221 can disposed above the luminescent unit 212.
Taking the integral forming of the optical element 221 and the mounting part 222 as an example, the optical element 221 is extended from a surface of the mounting part 222 and provided with an annular accommodating cavity (not marked) on a side facing the luminescent unit 212, so as to accommodate the luminescent units 212 through the accommodating cavity. The annular lens 221 is set to be hyperboloid or TIR configuration so as to extend or collimate the illuminated light.
The light source module 20 further includes a protective cover 23 for covering the light distribution component 22. The protective cover 23 is provided with an opening 231. The optical element 221 runs through the opening 231. Thus, the illuminated light emitted by the luminescent unit 212 can arrive at the target area after running through the optical element 221.
The shape of the protective cover 23 is close to the shape of the substrate 211. The protective cover is configured to protect the light distribution component 22 and the luminescent component 21 from being damaged by external collision. A top surface 232 of the protective cover 23 is bonded with the mounting part 222, or the top surface 232 of the protective cover 23 abuts against the mounting part 222. The protective cover 23 is detachably connected with the substrate 211, for instance, may be connected with the substrate 211 by fasteners, screws or other means. No further description will be given here.
The external interface 2131 in the luminescent component 21 runs through the protective cover 23, so as to provide convenience for the adapting and connection of the external interface 2131 and the power connector in the power supply module.
In the light source module 20 and the illumination device 100 employing the light source module 20, provided by the example of the present disclosure, the light source modules 20 taken as independent modules are mounted in the illumination device 100. When the lighting environment changes, the number of the light source modules 20 in the illumination device may be directly adjusted and an illumination device is not required to be repurchased, so the illumination device can be adapted to a variety of lighting environments.
