Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting, and particularly to a unitary multi-section variable LED ceiling lamp. Background Art

[0002] With the continuous development of aviation technology and the increasing requirements of passengers for comfort, the aircraft interior lighting system is also constantly improving. LED lighting technology, with its advantages of high efficiency, energy saving, long lifespan, etc., has gradually become an important part of the aircraft lighting system. As an innovative form of the application of LED lighting technology in the aircraft interior, the unitary multi-section variable LED ceiling lamp not only improves the lighting effect inside the aircraft but also enhances the comfort experience of passengers. To meet the diverse needs of passengers, the aircraft interior lighting system will pay more attention to humanized design, creating a more comfortable and warm boarding environment by adjusting parameters such as light intensity and color temperature.

[0003] During the traditional flight process, although the takeoff stage accounts for a relatively short time in the whole flight, the accident rate is relatively high. According to statistics, the takeoff stage and initial climb account for 2% of the whole flight, but the accident rate accounts for 14%. Therefore, passengers should stay alert when the plane takes off. Thus, we have designed a unitary multi-section variable LED ceiling lamp that uses the acceleration of the aircraft and the inertia of the lamp components when the plane ascends to converge the light for emergency situations; after the flight speed of the plane becomes uniform, the device resumes normal lighting, and the light diffuses and becomes softer, improving the comfort of passengers during the flight.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a unitary multi-section variable LED ceiling lamp, which has the following beneficial effects:

[0020] For this unitary multi-section variable LED ceiling lamp, a slide rail is provided on the lower surface of the housing. The number of the slide rails is greater than one, and the slide rails are arranged in a circumferential array on the housing with the midpoint of the LED lamp assembly as the center of the circle. A telescopic plate that can move along the slide rail is installed at the bottom of the slide rail. The telescopic plate is controlled by the circuit device inside the housing. One end of the telescopic plate facing the outside is fixedly connected with a telescopic magnet. A reflective wall is installed on the lower surface of the telescopic plate. A fixed magnet is designed at the upper end of the reflective wall, and a floating magnet is designed at the bottom. The reflective wall is connected to the telescopic plate through the magnetic force of attraction between the fixed magnet and the telescopic magnet; the reflective wall can move inward under the drive of the telescopic plate and merge to form a reflective bowl. When in use, since this device is a ceiling lamp, it is installed upside down on the ceiling. When the device is in the lighting state, the telescopic plate drives the reflective wall to move inward along the slide rail under the control of the internal circuit device until the reflective wall is closed and spliced into a complete reflective bowl. Then the telescopic plate continues to move into the housing. The reflective wall is limited by the end of the slide rail. The telescopic magnet is separated from the fixed magnet. The reflective wall has a downward movement tendency, but is supported by the repulsive force between the support magnet and the floating magnet, and thus becomes a floating state. When the plane takes off, due to the acceleration and the inertia of the reflective bowl itself, the reflective bowl will resist part of the repulsive force, and thus move downward, making the reflective bowl around the LED lamp assembly longer, making the emitted light more concentrated, increasing the light density. After the flight speed of the plane becomes uniform, the downward acceleration of the reflective bowl disappears, and the support magnet and the floating magnet regain balance, and the device resumes normal lighting, and the light is diffused and softer, improving the comfort of passengers during the flight.

[0021] For this unitary multi - section variable LED ceiling light, a divergence device is fixedly installed outside the LED lamp assembly. The whole divergence device is made of a light - transmissive material. A lens is installed at the bottom of the divergence device, and the part except the lens is made of a light - diffusing plate. The part of the divergence device except the lens is provided with more than two holes; a concave lens is inlaid and installed inside the holes, and the concave lens can be a single - sided concave lens or a double - sided concave lens. This design enables the light emitted by the LED lamp to be refracted by the concave lens on the outer wall of the divergence device located outside it, expanding the light range without increasing power consumption and saving electrical energy.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figure 1-3 shown, the unitary multi-section variable LED ceiling lamp includes a housing 1. An LED lamp assembly 2 is installed on the lower surface of the housing 1. The LED assembly is preferably located at the center of the housing 1, which is beneficial to reducing the overall volume of the device and making the device more compact. A plurality of grooves are formed on the lower surface of the housing 1, which are circumferentially and arrayed with the LED lamp assembly 2 as the midpoint. A slide rail 3 is designed inside the groove. The inside of the slide rail 3 communicates with the circuit device 5 above the LED lamp assembly 2. A telescopic plate 4 that can move along the slide rail 3 is installed at the bottom of the slide rail 3. The telescopic plate 4 is controlled by the circuit device 5 inside the housing 1. The circuit device 5 includes a telescopic mechanism inside, and the telescopic mechanism can adopt a hydraulic telescopic mechanism or an electric telescopic mechanism. This structure is a prior art and is not shown in the figure. One end of the telescopic plate 4 facing the outside is fixedly connected with a telescopic magnet 401. A reflective wall 6 is installed on the lower surface of the telescopic plate 4. A fixed magnet 601 is designed at the upper end of the reflective wall 6, and a floating magnet 602 is designed at the bottom. The reflective wall 6 is connected to the telescopic plate 4 by the magnetic force of attraction between the fixed magnet 601 and the telescopic magnet 401. The reflective wall 6 can move closer to the inside under the drive of the telescopic plate 4 and merge to form a reflective bowl A6. A light-transmitting glass cover 7 is designed and installed on the lower surface of the housing 1. The glass cover 7 wraps the slide rail 3 and the reflective wall 6 inside. A support magnet 701 is designed at the inner bottom of the glass cover 7. The support magnet 701 has the same magnetic pole as the floating magnet 602 and repels each other.

[0033] When the ceiling lamp is in the closed state, when the telescopic plate 4 is inside the slide rail 3, the telescopic magnet 401 and the fixed magnet 601 are adsorbed up and down. When the telescopic plate 4 continues to stretch and reach the circuit device 5, the telescopic magnet 401 and the fixed magnet 601 are separated under the block of the lower surface of the housing 1. The reflective wall 6 drops down to the upper part of the support magnet 701, and the support magnet 701 suspends and supports the reflective wall 6 equipped with the fixed magnet 601 upward through the repulsive force.

[0034] As Figure 4-7As shown, when the aircraft takes off, due to the acceleration and the inertia of the reflector bowl A6 itself, the reflector bowl A6 will resist part of the repulsive force and thus move downward, making the reflector bowl A6 around the LED lamp assembly 2 longer, making the emitted light more concentrated, increasing the light density. After the flight speed of the aircraft becomes uniform, the downward acceleration of the reflector bowl A6 disappears, and the supporting magnet 701 and the levitating magnet 602 resume balance, and the device resumes normal lighting, with the light spreading and becoming softer, improving the comfort of passengers during the flight.

[0035] As Figure 1 and 8 shown, a divergence device 8 is installed between the LED lamp assembly 2 and the reflecting wall 6. The divergence device 8 is integrally made of a light diffusion plate 801, which increases the lighting range while ensuring the light transmittance. A lens 802 is installed at the bottom of the divergence device 8, and the light-condensing angle of the lens 802 is twenty-five degrees or thirty-eight degrees.

[0036] As Figure 8 shown, a number of holes 803 greater than two are provided on the outer wall of the divergence device 8; a concave lens 804 is inlaid inside the holes 803. The concave lens 804 can be a double-sided concave lens 804 or a single-sided one, with the single-sided concave surface facing inward, so that the light emitted by the LED lamp assembly 2 diverges outward when passing through the concave lens 804.

[0037] As Figure 1 shown, the upper end of the divergence device 8 is designed with a threaded outer wall, and the divergence device 8 is connected to the cover 1 by means of the thread, which is convenient for disassembly, inspection, replacement.

[0038] As Figure 3 shown, this equipment is designed with an energy-saving mode. In the energy-saving mode, the telescopic plate 4 drives the reflecting wall 6 to move outward along the slide rail 3 under the control of the internal circuit device 5, reducing the influence on the light emitted by the divergence device 8, so that the light emitted by the LED lamp assembly 2 is emitted from the outer surface of the divergence device 8.

[0039] As Figure 1 shown, limiting magnets 603 are designed at the left and right edges of the reflecting wall 6. The limiting magnets 603 between adjacent reflecting walls 6 attract each other with opposite poles, ensuring that the reflecting wall 6 will not be misaligned in the levitating state. The magnetic force of the limiting magnet 603 should be less than the magnetic force between the fixed magnet 601 and the telescopic magnet 401.

[0040] As Figure 4-7 shown, the slide rail 3 is designed below the horizontal level of the lower surface of the cover 1, and the reflecting wall 6 is limited by the blocking of the cover 1 on both sides of the slide rail 3. The width of the slide rail 3 is the same as the upper end of the reflecting wall 6, so that the reflecting wall 6 has no freedom of movement except in the vertical direction.

[0041] As Figure 1 shown, the device is of a unitary structure, and the adjacent units are electrically connected through a flexible strip structure 9, and the flexible strip structure 9 is installed on both sides of the housing 1.

[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0043] The above description is only a preferred embodiment of the present application and an explanation of the technical principles applied. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, a technical solution formed by mutually replacing the above features with the (but not limited to) technical features having similar functions disclosed in the present application.
