FIG. 8 shows an example of such an automobile marker light a.
Is shown.

Reference numeral b is an automobile body, c is an inner body arranged inside the body b, and d is a rear windshield.

A is the rear windshield d
It is a stop lamp arranged inside the upper part of the, and is generally called a high mount stop lamp.

Reference numeral e denotes a lamp body of the high-mount stop lamp a, and the front surface (for the lamp, the light irradiation direction will be described as the front, so it does not coincide with the front-rear direction of the vehicle. The same applies to a main part g having a space f opened to a bracket part h protruding upward from the rear part of the main part g.

Reference numeral i denotes a printed circuit board arranged in a space f of the lamp body e, and a plurality of light emitting diodes (hereinafter referred to as "LEDs") j, j, ... Has been done.

Reference numeral k denotes a lens body attached to the lamp body e so as to cover the front side of the printed circuit board i.

Incidentally, 1 is a connector attached to the front side of the bracket portion h, and m is the connector 1 and the printed circuit board i.
It is a cord that connects between and.

However, such a high mount stop lamp a is arranged inside the upper part of the rear windshield d in the vehicle compartment by screwing the upper end of the bracket portion h to the rear end of the inner body c. It

[0011]

By the way, in the above-mentioned high mount stop lamp a, a certain clearance is provided between the high mount stop lamp a and the rear windshield d in order to absorb variations in mounting. n is generated. Therefore, LEDs j, j,
There is a problem that a part of the light emitted from ... is reflected by the inner surface of the rear windshield d and becomes light leakage, which hinders the rear view through the rearview mirror.

Further, there is a problem that a lot of man-hours are required for assembling the high mount stop lamp a and attaching it to the vehicle body, which is troublesome.

Further, the LED j that has passed through the lens body k,
The light of j, ... Must further pass through the rear windshield d, and in addition to the loss due to the transmittance of the lens body k, the loss due to the transmittance of the rear windshield d also causes the illuminance. There is a problem of decrease.

[0014]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an automobile marker light of the present invention has a plurality of light-emitting diodes arranged on the front surface of a printed circuit board and the printed circuit board is used as a rear windshield. The transparent cover body fixed to the outer surface and covering the front side of the printed circuit board is fixed to the rear windshield.

[0015]

Therefore, in the automobile marker light of the present invention, since the light emitting diode which is the light emitting source is located outside the rear windshield, the light of the light emitting diode is reflected on the inner surface of the rear windshield and leaks. It does not happen that the rear view through the rearview mirror is obstructed.

Further, since both the printed circuit board and the transparent cover body are directly fixed to the rear windshield, the total number of man-hours required for assembling the indicator light for an automobile and mounting it to the rear windshield can be extremely small.

Furthermore, since the member through which the light emitted from the light emitting diode is transmitted is only the transparent cover body, the loss of light is small and the illuminance can be increased.
