However, metal lamps, metal halide lamps, sodium lamps, and the like have low illuminance, high power consumption, and short life span, so that they are frequently replaced with metal halide lamps and sodium lamps. And thus it takes a lot of management and maintenance costs.

In addition, in the conventional lamp, the ballast for lighting is installed inside the column, and the ballast located in the lower part of the lamppost is short-circuited during the flood or rain, resulting in frequent occurrence of electric shock accident.

In order to solve the problems of such a conventional road lighting apparatus, a road lighting apparatus manufactured by applying a light emitting element made of LED (Light Emitting Diode, hereinafter referred to as LED) as a lamp has been variously developed .

These LEDs have advantages of simple lighting circuit, no need for inverter circuit and ballast, low power consumption and long lifetime, so that maintenance and repair costs are low.

The following prior art document discloses a streetlight unit manufactured by applying such an LED as a lamp.

1 is an exploded perspective view of a streetlight unit according to the prior art.

That is, the streetlight unit of the following prior art document is a technique for irradiating the road or the road through the LED module.

Referring to FIG. 1, a conventional streetlight unit includes a housing 100, an LED module 200 installed on an inner upper surface of the housing 100, and an LED module 200 detachably coupled to a lower surface of the housing 100 And a cover unit 300 disposed between the LED module 200 and the cover unit 300 and adapted to vary the angle of diffusion of the light emitted from the LED module 200 toward the cover unit 300, A reflection plate 400 moved along the longitudinal direction of the housing unit 100 and a driving unit 500 providing movement force for moving the reflection plate 400.

However, in the conventional street light unit, the cover unit 300, which is made of a transparent cover glass, is easily contaminated due to pollution sources such as yellow dust or fine dust, so that the lighting function is easily deteriorated. There are following problems.

In addition, although the conventional street light unit has a function of diffusing the light of the LED by the internal reflection plate 400, the LED can emit light only by using an external power source, which is disadvantageous in that it is not functionally scalable.
