Maintenance-free active heat radiating system of LED (Light Emitting Diode) lamp

Abstract

The invention discloses a maintenance-free active heat radiating system applied to an LED (Light Emitting Diode) lamp, and the system provided by the invention has the advantage of good heat radiating effect and basically does not have dust. In the maintenance-free active heat radiating system disclosed by the invention, a cyclone accelerator, an air filter, a cyclone dust shunt and a dust collector are arranged at the lower end of a hollow lamp post; the air inlet of the cyclone dust shunt is connected with outside air; after the air passes through the rotary channel of the cyclone dust shunt, large-grain dust is deposited into the dust collector by vrtue of a rotary acceleration; then, the clean air enters the middle channel of the cyclone dust shunt and is blown into the air filter and the cyclone accelerator; a heat radiator is arranged on an LED lighting assembly at the upper end of the lamp post; a through hole is drilled on the heat radiator; a fixed pipe and a heat radiating sheet are arranged at the upper face of the heat radiator; after the air supplied by the cyclone accelerator at the lower end in the lamp post enters the fixed pipe connected with the lamp post from an inner hole at the upper end of the lamp post, the air passes through the through hole through a vent pipe arranged at the other end of the fixed pipe and is blown into the air inlet of an air increaser through the other end of the through hole; and the air outlet of the air increaser is aligned with the heat radiating sheet to blow the air. The maintenance-free active heat radiating system disclosed by the invention has the advantage of good heat radiating effect and basically does not have dust.

Description

technical field [0001] The invention relates to heat dissipation technology for street lamps, in particular to a maintenance-free active heat dissipation system for LED lamps. Background technique [0002] Nowadays, more and more street lights on the road use LED lights. LED lights have low energy consumption and high brightness, and are widely used in various fields. However, LED street lights are facing two major problems: ① heat dissipation problem: LED is the best temperature at 25 degrees Working temperature, high brightness without attenuation, 25-80 degrees is about 5% attenuation, 80-100 degrees is 10%, 100-120 degrees is 20%, 120-140 degrees is 40%, so the heat dissipation of LED is very important. Due to the long continuous working hours of street lamps, it is necessary to have a cooling system. In order to ensure the working temperature of the LED street lamps, the current cooling system of the LED street lamps uses a high-power fan, which wastes energy, has a com...

[0002] Nowadays, more and more street lights on the road use LED lights. LED lights have low energy consumption and high brightness, and are widely used in various fields. However, LED street lights are facing two major problems: ① heat dissipation problem: LED is the best temperature at 25 degrees Working temperature, high brightness without attenuation, 25-80 degrees is about 5% attenuation, 80-100 degrees is 10%, 100-120 degrees is 20%, 120-140 degrees is 40%, so the heat dissipation of LED is very important

Due to the long continuous working hours of street lamps, it is necessary to have a cooling system. In order to ensure the working temperature of the LED street lamps, the current cooling system of the LED street lamps uses a high-power fan, which wastes energy, has a complex structure, and is too heavy; It can't solve the heat dissipation problem at all; ②Dust problem: At present, most LED street lights simply add a filter screen at the air inlet, which has poor filtering effect, and the filter screen needs to be replaced frequently, and the maintenance cost is too high
