Abstract

PURPOSE:To prevent the rearward visibility through a rear window shield from being obstructed and prevent the light leak due to the reflection on the inner surface of the rear window shield. CONSTITUTION:A rear window shield 1 is formed by superposing two transparent plates 2 and 3, and a gap 4 is formed by separating the upper edge parts 2a and 3a of two transparent plates, and a luminous unit 9 is arranged in the gap, and the opened port part of the gap is covered by the rear edge parts 7a and 7b of a ceiling member 7. The luminous unit is arranged in the gap formed in the upper edge parts of two transparent plates which constitute the rear window shield, and since a marker light is constituted of a part of the rear window shield and the luminous unit, the sign light can be assembled in compact form at the upper edge part of the rear window shield, and the rearward visibility through a rear view mirror is prevented from being obstructed, and the downward laak of light from the upper edge part of the rear window shield is prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a novel automobile marker light. More specifically, the present invention is intended to provide a novel automotive marker lamp that does not hinder the rear view through the rear windshield and prevents light leakage due to reflection on the inner surface of the rear windshield.

[0002]

2. Description of the Related Art In a vehicle such as a passenger vehicle whose vehicle height is lower than that of a truck, a bus, etc., in order to improve visibility of a following vehicle, the rear windshield is made to correspond to a high position. Attempts have been made to place stop lights and other indicator lights.

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

Reference numeral b denotes an automobile body, c an inner body arranged inside the body b, and d 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-back direction of the automobile. In the description of the embodiments described later. The same applies to a main part g having a space f opened to a bracket part h projecting upward from the rear part of the main part g.

Reference numeral i denotes a printed circuit board arranged in the 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.

In such a high mount stop lamp a, the upper end portion of the bracket portion h is screwed to the rear end portion of the inner body c and is disposed inside the upper portion of the rear windshield d in the vehicle compartment. It

[0011]

By the way, in the above-mentioned high mount stop lamp a, since it is mounted on the vehicle body in a state of being suspended from the ceiling member c, a rearview mirror and a rear windshield are installed from the driver. There is the problem of obstructing the rear view through d.

Further, a constant clearance n is created between the high mount stop lamp a and the rear windshield d in order to absorb variations in mounting. Therefore, there is a problem that a part of the light emitted from the LEDs j, j, ... Is reflected by the inner surface of the rear windshield d and becomes light leakage, which hinders the rear view through the rearview mirror.

[0013]

Therefore, in order to solve the above-mentioned problems, in the marker light for an automobile of the present invention, a rear windshield is formed by superposing two transparent plates, and the two transparent plates are formed. The upper end portion or the lower end portion of is separated from each other to form a gap, and the light emitting portion is arranged in the gap.

[0014]

Therefore, in the marker light for an automobile of the present invention, a gap is formed between the members constituting the rear windshield at the upper end portion or the lower end portion of the rear windshield, and the light emitting portion is arranged in the gap, and the rear windshield is disposed. Since it is composed of a part of the shield and the light emitting portion, it is compactly assembled on the upper end portion of the rear windshield and does not obstruct the rear view through the rearview mirror.

Further, since the light emitted from the light emitting portion does not leak downward from the upper end portion or the lower end portion of the rear windshield, it is reflected at a portion lower than the upper end portion of the rear windshield and heads forward to give a rear view. There is no interfering light leakage.
