Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to an AC / DC compatible lighting driving device. Background Art

[0002] Lighting driver technology compatible with AC and DC input is a lighting driver system that can operate under different power supply conditions. This solution effectively realizes the conversion of AC and DC power supply, and ensures that the electrical part of the lamp complies with relevant safety standards during the design and manufacturing process. It is suitable for most lighting products. Using a lighting driver technology solution compatible with AC and DC input to provide power for LED lighting can protect LED lamps from grid fluctuations or battery over-discharge. This technology takes into account factors such as the voltage and current levels of the input power supply, the power requirements of the lighting equipment, conversion efficiency and safety. At the same time, it also considers the cost and reliability of the product to ensure that the lighting driver system can meet the needs of actual applications. This technology can be applied to various lighting equipment.

[0003] Chinese Patent: CN114719212B discloses an AC / DC compatible lighting driver and a large basement lighting system, relating to the technical field of basement engineering. The device comprises a mounting base mounted on the ceiling, the mounting base defining a mounting cavity, the inner wall of which is rotatably provided with a first tube and a second tube, the first and second tubes being symmetrically arranged. The mounting base is provided with a first element for driving the first tube to rotate, and a second element for driving the second tube to rotate. The second tube is provided with a hollow housing at one end within the mounting cavity, a mounting post for mounting a light bulb is provided within the second tube, and a rotating ring is rotatably provided on the outer wall of the second tube. Two arcuate plates are symmetrically provided on the outer wall of the rotating ring, the arcuate plates being connected to the outer wall of the first tube at one end away from the rotating ring, and the housing is located between the two arcuate plates. This application has the effect of cleaning water droplets from the lighting device and cleaning its surface.

[0004] In the above patent, the cleaning member rotates with the arc plate and can clean the surface of the cover, and when it moves to the reversing member, the cleaning member can rotate on its own, thereby cleaning the surface of the cover from different angles. However, watermarks will remain on the surface of the cover, and the watermarks will decompose the light to a certain extent and produce halos. When the driver is driving a vehicle in the basement, the underground garage has poor light, which makes the driver easily disturbed by the halo, which in turn affects the driver's safe driving. In addition, during the return of the south wind, the temperature in the basement is lower than that outside, and the temperature difference between the inside and outside of the cover is large, which makes it easy to condense water dew, further reducing the lighting effect.

The height of the lighting device is adjusted by using the external thread 103 on the anchor rod 102 and the expansion sleeve to be threadedly connected, and the anchor rod 102 and the expansion sleeve are tightened by twisting the nut 104.

[0042] Specifically, such as Figure 1-Figure 5 and Figure 9The switching assembly 7 includes a switching head 701 that is sleeved in the docking hole 6. The interior of the switching head 701 is a hollow structure. A groove A702 is provided on the switching head 701 corresponding to the nozzle A504. A clamping head A703 is sleeved in the port of the groove A702. A supporting spring A704 is connected under the clamping head A703.

The two sides of the corresponding cleaning plate 503 on the slider A501 are respectively clamped with a nozzle A504 and a nozzle B505. The nozzles A504 and B505 are both The panel cleaning assembly 5 is connected to the docking hole 6 and further includes a transverse drive member 506 for driving the cleaning plate 503, the nozzle A504, and the nozzle B505 to sweep back and forth across the bottom of the cleaning plate 503.

[0046] The specific embodiment of the present invention is as follows: the hot air flowing to the three-phase connector 1003 enters the sealing cover 5061 and directly acts on the guide blade 1001. The guide blade 1001 rotates to drive the reciprocating screw 5062 to rotate. The slider B5063 on the reciprocating screw 5062 drives the slider A501 to slide back and forth in the slide groove 11. During this process, the slider A501 will drive the cleaning plate 503, the nozzle A504 and the nozzle B505 to reciprocate at the bottom of the light-transmitting plate 4. The slider A501 is in the slide groove 11. When sliding to one side, the switching head 701 will hit the end face inside the slide groove 11, and the inner top wall of the docking hole 6 is provided with a card slot corresponding to the card head A703 and the card head B706.

At this time, the docking interface B709 is connected to the nozzle head B505. As the slider A501 continues to slide, The switching head 701 is subjected to the lateral thrust and acts on the clamping head A703. The clamping head A703 is immersed in the card slot A under the action of the extrusion force and squeezes the support spring A704 to make it elastically deformed. The clamping head B706 moves to the corresponding card slot. The clamping head B706 is immersed in the card slot under the action of the return elastic force of the support spring B707. At this time, the interface A708 is connected with the nozzle A504. When the slider A501 slides to the other side in the slide groove 11, the switching head 701 is subjected to the thrust in the other direction. After the switching action is completed, the hot air acts on the guide blade 1001 and flows into the switching head 701 through the bridge pipe 1006.

Then, the nozzle head A504 or nozzle head B505 behind the moving direction of the cleaning plate 503 sprays a hot air flow to act on the light-transmitting plate 4.
