LIGHTING APPARATUS

FIELD

The present invention is related to a lighting apparatus, and more particularly related to a lighting apparatus with a flexible configuration.

BACKGROUND

LED (Light Emitting Diode) technology has undergone significant development since its inception in the early 20th century. The first practical LED was developed in 1962 by Nick Holonyak Jr., a scientist at General Electric. Initially, LEDs were limited to emitting low-intensity red light and were used primarily as indicator lights in electronic devices. These early LEDs were inefficient and expensive, which restricted their applications. However, the fundamental principle of electroluminescence, where materials emit light in response to an electric current, laid the groundwork for future advancements.

Throughout the 1970s and 1980s, improvements in materials and manufacturing techniques led to the development of LEDs that could emit light in different colors, including green and yellow. These advancements were driven by the discovery and utilization of new semiconductor materials like gallium phosphide and gallium arsenide. Concurrently, researchers worked on enhancing the efficiency and brightness of LEDs, making them more suitable for practical applications. By the late 1980s, LEDs were being used in digital displays, traffic lights, and signage, though they were still not efficient enough for widespread lighting applications.

The breakthrough that revolutionized LED technology came in the 1990s with the development of blue LEDs by Shuji Nakamura and his colleagues. Using gallium nitride (GaN) and indium gallium nitride (InGaN) as the semiconductor materials, they were able to create high-brightness blue LEDs. This innovation was crucial because it enabled the creation of white light LEDs by combining blue LEDs with phosphors that convert blue light to white light. This breakthrough not only expanded the range of applications for LEDs but also paved the way for their use in general lighting.

As the 21st century progressed, LED technology continued to evolve rapidly. Advances in materials science, particularly the development of more efficient phosphors and quantum dot technologies, have significantly improved the color rendering and efficiency of LEDs. Additionally, improvements in manufacturing processes, such as the development of epitaxial growth techniques and surface coating technologies, have reduced production costs and increased the durability of LEDs. These enhancements have made LEDs the preferred choice for a wide range of applications, from residential and commercial lighting to automotive and outdoor lighting.

Today, LED technology is at the forefront of the lighting industry, driven by its energy efficiency, long lifespan, and versatility. LEDs consume significantly less energy compared to traditional incandescent and fluorescent bulbs, resulting in lower electricity bills and reduced environmental impact. Their long operational life, often exceeding 50,000 hours, reduces the need for frequent replacements, further contributing to their cost-effectiveness and sustainability. The versatility of LEDs allows for innovative lighting solutions, including smart lighting systems that can be controlled remotely and integrated into smart home ecosystems.

Looking ahead, the future of LED technology is promising, with ongoing research focusing on enhancing efficiency, reducing costs, and expanding applications. Emerging technologies such as organic LEDs (OLEDs) and micro-LEDs are poised to further transform the lighting and display industries.

Their small size and ability to be integrated into compact and innovative designs make them ideal for applications where traditional bulbs would be impractical. For example, LEDs are extensively used in automotive lighting, including headlights, tail lights, and interior lights, due to their durability, energy efficiency, and ability to produce bright, focused light. In the entertainment industry, LEDs are used in stage lighting, displays, and screens, offering vibrant colors and dynamic lighting effects that enhance performances and visual experiences.

In the realm of smart lighting, LEDs are a natural fit due to their compatibility with digital controls. Smart LED bulbs can be controlled remotely via smartphones or integrated into smart home systems, allowing users to adjust brightness, color, and timing according to their preferences. This capability not only adds convenience and customization but also contributes to energy efficiency through features like automatic dimming and motion detection. Moreover, the ability to control LED lighting remotely and programmatically makes them ideal for applications in smart cities, where streetlights and public lighting can be managed centrally to optimize energy use and maintenance schedules.

The environmental benefits of LED technology extend beyond energy efficiency and long lifespan. LEDs are free of hazardous materials such as mercury, which is present in fluorescent bulbs, making them safer for both users and the environment. Their reduced energy consumption means lower greenhouse gas emissions from power plants, contributing to efforts to combat climate change. Additionally, the development of recycling programs specifically for LEDs is making it easier to dispose of them responsibly, further minimizing their environmental impact.

Overall, the features of LED technology—energy efficiency, long lifespan, versatility, and environmental friendliness—have made them the preferred choice for a wide range of lighting applications.

The multiple LED modules 601 are disposed on a front side 6022 of the light source plate 602.

The guiding unit 606 is attached to the light source plate 602 so that a protruding portion 6061 of the guiding unit 606 is protruded from a back side 6021 of the light source plate 602 extending downwardly.

The top housing 613 includes a light source housing 603 and a first sleeve housing 604.

The guiding unit 606 is enclosed by the first sleeve housing 604.

The light source housing 613 is used for disposing the light source plate 602 and has a light opening 6025.

A light of the multiple LED modules passes through the light opening 6025.

The driver module 607 converts an external power 612 to generate driving currents to the multiple LED modules 601.

The bottom housing 605 is used for disposing the driver module 607.

The bottom housing 605 has a second sleeve housing 6051.

The second sleeve housing 6051 encloses the driver module 607.

The first sleeve housing 604 and the second sleeve housing 6051 are connected so that the first sleeve housing 605 and the second sleeve housing 6051 are capable of being moved relative to each other along a longitudinal direction 610 of the connection to alter a total longitudinal length 615 of a combined structure of the first sleeve housing 605 and the second sleeve housing 6051.

The Edison cap 609 is attached to the bottom housing for receiving the external power 612.

FIG. 8 shows a relative movement between the second sleeve housing 6051 and the first sleeve housing 604 to change the total longitudinal length 6151.

Other components in FIG. 8 with the same reference numerals in FIG. 7 refer to the same components and would not be explained again for brevity. FIG. 7 together with FIG. 8 show how the first sleeve housing is moved with respect to the second sleeve housing to change the total longitudinal length.

In some embodiments, the guiding unit routes electricity from the driver module to the LED modules. For example, the guiding unit includes a conductive path. No matter how the total longitudinal length is changed in FIG. 7 and FIG. 8, the driver module is electrically connected to the LED modules via the guiding unit.

In some embodiments, the first sleeve housing encases and slides over the second sleeve housing. FIG. 7 and FIG. 8 show such case.

In FIG. 9, the second sleeve housing 624 encases and slides over the first sleeve housing 623. In FIG. 9, the second sleeve housing 624 has a larger diameter than the first sleeve housing 623. Their relative movement, like in FIG. 7 and FIG. 8, is along a longitudinal direction 625.

In FIG. 9, a first diameter 621 of the light source housing is larger than 3 times of a second diameter 622 of the first sleeve housing. Such arrangement makes a normal Edison bulb converting to appear like a panel light device while having the convenience to be installed on an Edison socket.

An Edison socket, also known as an Edison screw base, is a type of light bulb socket that is widely used around the world for various lighting applications. Named after Thomas Edison, who developed the original design, the Edison socket features a threaded metal base that allows for secure mechanical and electrical connections with corresponding light bulbs. The most common type of Edison socket is the E26, where “E” stands for Edison and “26” denotes the diameter of the base in millimeters. Other variations include the E27, E14, and E12, which differ in size but operate on the same principle. The threaded design ensures that the light bulb can be easily screwed into and out of the socket, providing a reliable and user-friendly interface for lighting installations.

An Edison cap, also referred to as an Edison screw cap, is the complementary component to the Edison socket. It is the base part of the light bulb that screws into the Edison socket to establish an electrical connection. The Edison cap is typically made of metal and features threads that match the corresponding socket, allowing it to be securely fastened. Inside the Edison cap, there are contact points that interface with the electrical contacts within the socket, ensuring the proper flow of electricity to power the light bulb. This design not only facilitates a strong physical connection but also ensures efficient electrical conductivity, making it a preferred choice for various lighting applications.

The Edison socket and Edison cap work together to transmit electricity from the power source to the light bulb or light device. When the light bulb, equipped with an Edison cap, is screwed into the Edison socket, the threads on the cap engage with the threads in the socket, securing the bulb in place. The contact points on the Edison cap then align with the electrical contacts within the socket, completing the electrical circuit. Once the circuit is completed, electricity flows from the power source through the socket and cap, reaching the filament or LED within the bulb, thereby producing light. This mechanism is simple yet highly effective, providing a reliable means of connecting light bulbs to electrical sources and facilitating the widespread adoption of Edison-based lighting systems in residential, commercial, and industrial settings.

The first diameter and the second diameter are measured perpendicular to the longitudinal direction, which is clearly demonstrated as an example in FIG. 9.

FIG. 3 shows an example of such metal grooves 701 on a guiding unit example. In addition, in FIG. 3, the driver module has a metal clip 71 to fit to one of the metal grooves. When the driver module is moved relative to the guiding unit, the metal clip is fallen in different metal groove 701. However, even the relative distance is changed, the driver module is still electrically connected to the LED modules via the guiding unit.

The multiple metal grooves are disposed along the sliding path.

When the elastic metal clip is fallen in one of the multiple metal piece grooves.

There is a resistance force preventing the first elongated plate to move with respect to the second elongated plate.

FIG. 10 shows that the top housing 628 and the bottom housing 627 is moved by rotating to change their relative distance in the longitudinal direction 625.

In some embodiments, the total longitudinal length determines an optical parameter of the multiple LED modules. For example, when the total longitudinal length 615 in FIG. 7 refers to a first optical parameter while the total longitudinal length 6151 may refers to a different optical parameter like a color temperature, a color, a light intensity.

In some embodiments, the optical parameter includes a color temperature.

A first total longitudinal length corresponds to a first color temperature.

A second total longitudinal length corresponds to a second color temperature.

The first color temperature is different form the second color temperature.

In some embodiments, the lighting apparatus may also include a lens cover.

When the total longitudinal length is changed, a output light pattern is changed when a relative position between the lens cover and the multiple LED modules is changed.

FIG. 11A and FIG. 11B show an example to change a relative distance between the light source 637 and the lens cover 631, the light spanning angle 634 is changed to light spanning angle 635. The light source 637 is disposed on the light source plate 632.

FIG. 12A and FIG. 12B show an example to change a relative distance between the light source 637 and the separating wall 636. The light source 637 is disposed on the light source plate 632.

In the example of FIG. 11A and FIG. 12A, the lens cover and the separating wall may be disposed on the second component that moves relative to the first component that holds the light source with a similar structure as mentioned above to make two components to move relatively.

In FIG. 7, a data receiver 661 disposed on the light source plate sends a signal to the driver module as a reference for the driver module to control the lighting apparatus.

The data receiver 661 may include a wireless process, a wireless antenna, a light detector, a smoke detector, or any other sensor.

When the movable component 8 moves to a certain position, the second elastic terminal 81 moves to a certain positioning hole 91 on the limiting plate 9, producing a sound to indicate the position.

The working of the telescopic lamp is described as follows.

The telescopic lamp of this application includes a thumbtack, a lamp head, a fixing component, a heat dissipation component, a movable sleeve, a sealing ring, a driving component, a movable component, a limiting plate, a light source assembly, and a housing. The thumbtack is fixed to the lamp head, which in turn is fixed sequentially to the fixing component and the movable sleeve. The sealing ring is placed on the outer periphery of the movable sleeve and then placed inside the heat dissipation component. The driving component is fixed to the movable sleeve, while the movable component is placed inside the movable sleeve and fixed inside the heat dissipation component. The limiting plate is fixed to the movable sleeve, and the light source assembly is fixed to the heat dissipation component. The housing is fixed to the heat dissipation component.

The driving component includes first elastic terminals with a spring structure, which contact the bare copper structures on the surface of the movable component to achieve electrical connection between the movable component and the driving component. The limiting plate and the movable component interact with each other, with multiple positioning holes arranged along the displacement direction of the movable component on the limiting plate. The side of the movable component near the limiting plate is provided with second elastic terminals. When the movable component moves to a specific position, the second elastic terminals move into a corresponding positioning hole in the limiting plate, producing a sound to indicate reaching that position.

When the telescopic lamp performs a telescoping motion, the heat dissipation component, movable component, light source assembly, and housing move as one part in one direction, while the driving component, limiting plate, sealing ring, movable sleeve, fixing component, lamp head, and thumbtack move as another part in the opposite direction. This design allows the lamp to extend and retract freely, ensuring efficient operation and ease of use.
