This solution effectively realizes the conversion of AC and DC power supply, and ensures that the electrical part of the lamp meets the relevant safety standards during the design and manufacturing process. It is suitable for most lighting products. Using lighting driver technology solutions compatible with AC and DC input to provide power for LED lighting can protect LED lamps from grid fluctuations or excessive battery discharge. This technology takes into account 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 drive system can meet the needs of actual applications. This technology can be applied to various lighting equipment.

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 clamp A703 is sleeved in the port of the groove A702. A support spring A704 is connected under the clamp A703. The clamp A703 is elastically supported and connected to the inner bottom of the groove A702 through the support spring A704.

The board cleaning assembly 5 includes a combination seat 502 connected to the slider A501, and a cleaning plate 503 for cleaning the light-transmitting plate 4 is installed inside the combination seat 502. The slider A501 is clamped on both sides of the cleaning plate 503, and the nozzle A504 and the nozzle B505 are respectively clamped. The board cleaning assembly 5 is connected to the docking hole 6, and further includes a transverse driving member 506 for driving the cleaning board 503, the nozzle A504 and the nozzle B505 to sweep back and forth at the bottom of the cleaning board 503. The transverse driving member 506 includes a sealing cover 5061 connected to the lampshade 3, and a reciprocating screw 5062 is rotatably connected to the inner side of the sealing cover 5061.

A bridge tube 1006 is clamped on the partition plate 1002 , and the other end of the bridge tube 1006 is connected to the switching head 701 .

[0025] The specific implementation of this embodiment 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 slot corresponding to the clamp head A703 and the clamp head B706. At this time, the clamp head A703 is located in the slot under the support of the support spring A704, and the clamp head B706 is in a misaligned state with the corresponding slot, so that the end of the clamp head B706 is immersed in the groove B705, and the support spring B707 is in a compressed state. At this time, the docking interface B709 is connected with the nozzle 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 sinks into the card slot A under the action of the extrusion force and squeezes the supporting spring A704 to make it elastically deformed. The clamping head B706 moves to the corresponding card slot. The clamping head B706 sinks into the card slot under the action of the restoring elastic force of the supporting spring B707. At this time, the interface A708 is connected with the jet head A504. When the slider A501 slides to the other side in the slide slot 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 then flows into the switching head 701 through the bridge tube 1006. The hot air flowing into the switching head 701 flows into the nozzle A504 through the docking port A708 or flows into the nozzle B505 through the docking port B709. The cleaning plate 503 slides on the bottom of the light-transmitting plate 4 to effectively remove the condensed water on the light-transmitting plate 4. Then, the nozzle A504 or nozzle B505 behind the moving direction of the cleaning plate 503 sprays hot air flow to act on the light-transmitting plate 4.
