[0035] The plunger 13 is respectively sleeved with a second limit block 29, a second return spring 30 and a second fixed block 31, and the second limit block 29, the second return spring 30 and the second fixed block 31 are all located in the first In the inner cavity of the two limiting grooves 28, the second limiting block 29 is slidably connected to the second limiting slot 28, and two ends of the second return spring 30 are respectively connected to the side walls of the second limiting block 29 and the second fixing block 31.
[0036] The working principle of the present invention is:
[0037] When in use, the light board 2 conducts the heat generated by the LED lamp to the heat sink 4, the heat sink 4 conducts the heat to the heat sink 6, and the heat sink 6 conducts the heat to the cavity above the fixed board 5. Ventilation holes 20 are provided on the left and right sides of the housing 1 to generate convective air inside the housing 1, thereby cooling the heat sink 6. At the same time, since the hot air is rising, the hot air inside the housing 1 will pass through the ventilation The port 32 spreads out of the casing 1, so as to achieve the effect of heat dissipation. When the temperature is too high, the temperature sensor 8 is set. When the temperature is higher than the set value, the temperature sensor 8 transmits the signal to the fan 7. At this time, the fan 7 Start to blow and dissipate the inside of the housing 1, thereby achieving better heat dissipation and prolonging the life of the LED lamp. The dust-proof net 14 and the dust-proof cover 33 are set to effectively prevent external dust from entering the housing. The inside of the body 1 pollutes the LED lights and affects the use of LEDs. By pressing the pressure plate 17, the movable rod 16 pushes the first limit block 22 to move downward, so that the clamping block 18 leaves the clamping slot 19, so that the The removal of the dust-proof net 14 facilitates the cleaning and replacement of the dust-proof net, and improves the utilization of the dust-proof net 14. By pulling the plunger 13, the end of the plunger 13 leaves the slot 26 and the second through hole 27 At this time, the second connection block 10 is separated from the first connection block 9 so that the lamp cover 11 can be disassembled, which facilitates the replacement of the LED lamp group 3.
[0038] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
