InactiveCN107559715ASimple structureInnovative designLighting heating/cooling arrangementsOutdoor lightingEngineeringLighting system
The invention discloses a new type of LED street lamp, which comprises a lamp pole, a shell, a light-transmitting plate, a connecting pipe, a vacuum pipe, an LED bulb, a mounting plate, a cooling plate, a fan blade, a heat sink, a motor, an output shaft, a semiconductor Refrigeration fins, miniature vacuum pumps, heat dissipation fins, air extraction nozzles, hinges, box doors, springs, filter screens, guide rods, electric push rods, push plates and dust boxes. The invention is simple in structure, novel in design, reasonable in design, and convenient to use; the heat generated by the LED lamp can be dissipated in time through the semiconductor cooling sheet and the fan blade, so that the LED lamp is not affected by high temperature, ensures the lighting effect of the LED lamp, and prolongs the length of the LED street lamp. The service life of the LED street light is reduced, and the maintenance rate of the LED street light is reduced; the negative pressure can be formed in the dust collection box through the micro-vacuum pump, which can effectively absorb the dust in the shell, keep the inside of the shell clean, prevent the LED street light from being damaged, and ensure The normal operation of the road lighting system has a good market prospect and is suitable for promotion and use.
