In this process, air naturally flows in and out through the air vent 21 of the rear case 20. Cooling of the heat dissipation plate 50 to which the heat of the LED 42 is transferred is efficiently performed while contacting the outer circumferential surface of the 50 or moving along the through hole 51 of the heat dissipation plate 50.

이처럼 상기 엘이디(42)가 발광되면서 발생되는 열을 효과적으로 자연냉각시켜 상기 엘이디(42)를 이용한 가로등의 설치가 가능한 것이다.As such, the LEDs 42 may naturally cool the heat generated while the LEDs 42 emit light to install a street light using the LEDs 42.

이와 같이, 가로등에 적용된 엘이디모듈(40)은 전기에너지를 90% 를 빛을 바꿀 수 있어, 동일한 조건하에서 나트륨등과 수은등에 비해 고휘도의 빛을 조사할 수 있으며, 가격은 비싸지만 반영구적으로 사용가능하고, 전력소비를 최소화할 수 있는 것이다.As such, the LED module 40 applied to the street lamp can change the light of 90% of the electrical energy, so that it can irradiate light of higher luminance than sodium lamp and mercury lamp under the same conditions, and the price is high but can be used semi-permanently. And the power consumption can be minimized.
