The heat dissipation member 43a is fixedly installed on the inner surface of the canopy 41 and is applied to release heat generated from the light source unit 43 and is formed of a material having excellent thermal conductivity, for example, aluminum material. In addition, the heat radiating member 43a is preferably connected to the common terminal on the circuit board 43c.

The circuit board 43c supports the light emitting diode, and is coupled to the heat dissipation member 43a to support the first light source portion 43d and the second light source portion 43e by maintaining a predetermined interval.

The first light source portion 43d is provided on the circuit board 43c and is used to illuminate the surroundings when fog does not occur. The plurality of first light emitting diodes 143d is formed.

The second light source part 43e is installed on the circuit board 43c at predetermined intervals with the first light source part 43d to illuminate the surroundings when fog is generated. The second light source part 43e has a light having a wavelength longer than that of the first light emitting diode 143d. It consists of a plurality of second light emitting diodes (143e) emitting. Here, the second light emitting diode 143e preferably includes a yellow light emitting diode that emits light having a long wavelength.

For example, in FIGS. 2 and 3, the first light source unit 43d and the second light source unit 43e are installed on the circuit board 43c at predetermined intervals, but the light is irradiated. However, the first light source unit is not limited thereto. 43d and the second light source portion 43e may be independently provided on the inner surface of the canopy 41 to irradiate light.

In addition, as shown in FIG. 5, the first light source part is made of a first lamp 243d, and the second light source part is made of a second lamp 243e that emits light of a relatively longer wavelength than the first lamp 243d. Can be. In this case, it is preferable to apply a lamp having a bright brightness such as a halogen lamp or a mercury lamp as the second lamp.

The inner surface of the reflective member 44 is formed of aluminum, silver, or chromium, and a transparent coating film may be formed on the surface of the reflective member 44 to prevent oxidation due to contact with air.

The canopy cover 42 is coupled to the lower portion of the canopy 41 as shown in FIGS. 2 and 3 to form a closed space and has a transparent or translucent material. Here, a focusing lens is formed at the edge of the canopy cover 42 to focus light that is scanned radially through the opening. The focusing lens may be integrally formed with the canopy cover 52 made of a transparent material. The focusing lens may be formed of a convex lens having positive power, and the curvature radius of the inner surface and the outer surface may be different from each other.
