Also, due to the light of the daytime and nighttime lighting unit, the ventilation of the nearby vehicles and pedestrians, The end and height of the loading box C1 can be confirmed).

The light emitting portion 40 for ventilation of the daytime or nighttime state includes a plurality of LEDs 41 and a condenser lens 43 provided in each LED and having a conical receiving groove 43A and an outer tapered convex portion for preventing a yellow ring, .

The LED 41 can be connected to a socket type like an ordinary bulb and can be energized (can be supplied from a car battery) or a type mounted on a PCB.

The condenser lens 43 provided for each LED 41 has a dome type structure to appropriately diffuse light while collecting light. The condenser lens 43 has a conical receiving groove 43A so that the LED 41 and the lens are separated from each other, So that the characteristics can be secured.

The condenser lens 43 has four corners of the lower periphery to be inserted into corresponding grooves of the fixed panel 49 such as a PCB or other fixed plate and has a regular arm 47. The condenser lens 43 is inserted into the hole Shaped fixing member 45 which is formed on the outer circumferential surface thereof.

Furthermore, in order to prevent the generation of a yellow ring which is generated due to the characteristic of the dome-type condensing lens 43 and hinders the luminance characteristic and the light diffusion characteristic, it is preferable that the condenser lens includes an outer tapered convex portion 43a.

Further, the prevention of the yellow ring can be further strengthened through the additional tilting portion 43b formed in the bottom portion of the condenser lens 43,

In addition, in order to prevent the yellow ring and adjust the light diffusion property, the non-projecting portion 43c can be further formed on the conical inner wall of the receiving groove 43A.
