[0001] The invention relates to the technical field of LED lighting, in particular to a unit-type multi-section variable LED ceiling lamp. Background Art

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

[0003] In the traditional flight process, although the take-off phase accounts for a relatively short period of time in the entire flight, the accident rate is relatively high. According to statistics, the take-off phase and initial climb account for 2% of the entire flight, but the accident rate accounts for 14%. Therefore, passengers should remain alert when the plane takes off. Therefore, we designed a unit-type multi-section variable LED ceiling light, which uses the acceleration of the aircraft when the aircraft rises and the inertia of the lamp to converge the light in preparation for emergency situations; after the aircraft's flight speed is uniform, the device resumes normal lighting, and the light is diffused and softer, improving the comfort of passengers during the flight.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a unit-type multi-section variable LED ceiling lamp, which has the following beneficial effects: The unit-type multi-section variable LED ceiling lamp has a slide rail on the lower surface of the cover, the number of the slide rails is greater than one, and the slide rails are distributed on the cover in a circular array with the midpoint of the LED lamp assembly as the center of the circle.

After that, the telescopic plate continues to move into the inside of the housing, the reflective wall is limited by the end of the slide rail, the telescopic magnetic block is separated from the fixed magnetic block, and the reflective wall has a downward movement trend, but is supported by the repulsive force between the supporting magnetic block and the suspended magnetic block, thereby becoming a suspended state. When the aircraft 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 move downward, making the reflective bowl around the LED lamp assembly longer, making the emitted light more concentrated, and increasing the light density. After the aircraft's flight speed is uniform, the downward acceleration of the reflective bowl disappears, the supporting magnetic block and the suspended magnetic block regain balance, the device resumes normal lighting, the light is diffused and softer, and the comfort of passengers during the flight is improved.

[0016] The unit-type multi-section variable LED ceiling lamp has a diffuser fixedly installed on the outside of the LED lamp assembly. The diffuser is made of a light-transmitting material as a whole. A lens is installed at the bottom of the diffuser. The parts other than the lens are made of a light diffusion plate. The diffuser is provided with more than two holes except the lens. A concave lens is embedded inside the hole. The concave lens can be a single-sided concave lens or a double-sided concave lens. This design allows the light emitted by the LED lamp to be refracted by the concave lens on the outer wall of the diffuser located outside the LED lamp when it is irradiated to the outer wall of the diffuser. This expands the light range and saves electricity without increasing power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-3As shown, the unit-type multi-section variable LED ceiling lamp includes a cover 1, and an LED lamp assembly 2 is installed on the lower surface of the cover 1. The LED assembly is located at the center of the cover 1 as much as possible, which is conducive to reducing the total volume of the device and making the device more compact; the lower surface of the cover 1 is provided with a plurality of grooves distributed in a circular array with the LED lamp assembly 2 as the midpoint, and a slide rail 3 is designed inside the groove. The inside of the slide rail 3 is connected to the circuit device 5 above the LED lamp assembly 2, and 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 cover 1, and the circuit device 5 includes a telescopic mechanism inside. 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. It is shown that a telescopic magnetic block 401 is fixedly connected to one end of the telescopic plate 4 facing outward, a reflective wall 6 is installed on the lower surface of the telescopic plate 4, a fixed magnetic block 601 is designed on the upper end of the reflective wall 6, and a suspended magnetic block 602 is designed on the bottom, and the reflective wall 6 and the telescopic plate 4 are connected by the magnetic force of attraction between the fixed magnetic block 601 and the telescopic magnetic block 401; the reflective wall 6 can be moved inwardly under the drive of the telescopic plate 4 to form a reflective bowl A6; a light-transmitting glass cover 7 is designed and installed on the lower surface of the cover shell 1, and the glass cover 7 wraps the slide rail 3 and the reflective wall 6 inside, and a supporting magnetic block 701 is designed on the inner bottom of the glass cover 7, and the supporting magnetic block 701 and the suspended magnetic block 602 have the same magnetic poles and repel each other; When the ceiling lamp is in a closed state, when the telescopic plate 4 is located inside the slide rail 3, the telescopic magnetic block 401 and the fixed magnetic block 601 are adsorbed up and down, and when the telescopic plate 4 continues to telescope to reach the circuit device 5, the telescopic magnetic block 401 and the fixed magnetic block 601 are separated under the obstruction of the lower surface of the cover shell 1, and the reflective wall 6 falls downward to the upper part of the supporting magnetic block 701, and the supporting magnetic block 701 suspends and supports the reflective wall 6 equipped with the fixed magnetic block 601 upward through repulsion.

[0021] like Figure 4-7 As shown, when the aircraft takes off, due to the acceleration and the inertia of the reflective bowl A6 itself, the reflective bowl A6 will resist part of the repulsive force and move downward, making the reflective bowl A6 around the LED lamp assembly 2 longer, making the emitted light more concentrated and increasing the light density. After the aircraft's flying speed is uniform, the downward acceleration of the reflective bowl A6 disappears, the supporting magnetic block 701 and the suspended magnetic block 602 regain balance, the equipment resumes normal lighting, the light is diffused and softer, and the comfort of passengers during the flight is improved.

The diverging device 8 is made of a light diffusion plate 801 as a whole, which increases the illumination range while ensuring the transmittance. A lens 802 is installed at the bottom of the diverging device 8, and the focusing angle of the lens 802 is twenty-five degrees or thirty-eight degrees.

[0025] like Figure 3 As shown, the equipment is designed with an energy-saving mode. In the energy-saving mode, the telescopic plate 4, under the control of the internal circuit device 5, drives the reflective wall 6 to move outward along the slide rail 3, reducing the impact on the light emitted by the divergent device 8, so that the light emitted by the LED lamp assembly 2 is emitted from the outer surface of the divergent device 8.

[0026] like Figure 1 As shown, limiting magnets 603 are designed at the left and right edges of the reflective wall 6, and the limiting magnets 603 between adjacent reflective walls 6 attract each other with opposite poles to ensure that the reflective wall 6 will not be misplaced in the suspended state, and the magnetic force of the limiting magnet 603 should be smaller than the magnetic force between the fixed magnetic block 601 and the telescopic magnetic block 401.

[0027] like Figure 4-7 As shown, the slide rail 3 is designed to be below the level of the lower surface of the cover shell 1, and the reflective wall 6 is limited by the blocking of the cover shell 1 on both sides of the slide rail 3.
