Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a automobile compound taillight, particularly to one having different lighting functions provided at a rear side of an automobile and composed of a main base, a main light base, a side light base and a bottom base, and a sealed electric circuit board and a plurality of LED lamps provided respectively in the main light base, the side light bass and the bottom base to make signals completely separately and insulated from the exterior in a waterproof way to prolong its service life and also possible to be repaired easily.

2. Description of the Prior Art

A conventional automobile taillight shown in FIG. 1 includes a main base (A), a main light base (B), a main cover (C), a side cover (D), and a bottom cover (E). The main base (A) is opaque, having a position tube (A1) with two threaded holes on an inner surface, and an opening respectively in a front side, a left side and a bottom side, a plurality of female-threaded tubes (A2) in an inner surface of the front opening, a female-threaded tube (A3) respectively at two sides of the left opening, and an engage groove (A4) in an inner surface of the bottom opening.

The main light base (B) has a hole (B2) respectively at two sides, and a side light base (B 1) extending from one side, and a light bulb is respectively fitted in the main light base (B) and the side light base (B2)

The main cover (C) is colored and transparent, having a swelled-up circular surface in the center portion, The side cover (D) is colored and transparent, having a hole respectively at two sides.

The bottom cover (E) is not colored and transparent, having plural projections (E1) on two side edges. The bottom cover (E) is received in the interior of the main base (A), with the projections (E1) fitting in the engage grooves (A4) of the main base (A) by means of outer pressure of the bottom opening of the main base (A).

The main light base (B) is fixed with the bottom base (A) by screws (F) inserted through the holes (B2) and screwing with the position tubes (A1) and also protruding out. Further, the side light base (B 1) faces the left side opening of the main base (A) and the main light base (B) faces the front opening of the main base (A). The main cover (C) closes up the front opening of the bottom base (A), with screws (G) passing through the holes (C 1) and then engaging with the female-threaded tubes (A2). Further, the side cover (D) closes up the side opening of the bottom base (A), with screws (H) passing through the holes (D1) and engaging with the female-threaded tubes (A 3). In addition the whole taillight is secured above a license plate by the screws (F) also engaging the license plate frame and washers.

However, the conventional automobile compound tail light makes use of the light bulb in the main light base to shine through the main cover to function as a brake light, a direction light, and at the same time shines through the bottom cover to cast light on the license plate. In addition, the light bulb in the side light base shines through the side cover to function as a side-indicating light. By the way, the main base closed by the main cover, the bottom cover and the side cover has an open interior to permit the main cover, the bottom cover and the side cover glitter at the same time when the light bulb of the main light base is lit up to flash so that light beam may be shot out through the three sides of the main base, impossible to represent the exact function of indication. Moreover, the light beam that the conventional light bulb gives out is quite weak, not meeting the demand of the modern traffic safety regulations. And in addition, the conventional light bulb and the main light base are not processed with waterproof means, apt to cause breakage in case of high temperature or water leakage in case of raining.

The main base further has plural position bars spaced apart around the inner surface of the front opening, and a circular wall on the center portion of a rear surface of the main light cover.

Another feature of the invention is the main light base positioned in the main base at the front opening, shaped as a opaque square dish, having a chamber in the center portion of a front surface, an electric circuit board and plural LED lamps arranged in the chamber. The chamber has a cord groove formed in an upper side, and a curved wall on two opposite sides, a position groove formed in the center portion of each curved wall. Further a hole is provided respectively at four corners of the main light base, and a first fixing member is fixed at the right side of the rear surface, and a second fixing member at the bottom of the rear surface.

Another feature of the invention is the side light base of an opaque elongate dish shape, positioned at the side opening of the main base, having a chamber opening outward, an electric circuit board and plural LED lamps in the chamber, a cord groove formed in a bottom, and a pair of U-shaped fitting walls formed in a front surface.

The last feature of the invention is the bottom light base of an opaque elongate dish shape, positioned in the main base at the bottom opening, having a chamber opening downward, two fitting tubes protruding through the upper wall and forming a glue blocking wall extending rearward, an electric circuit board and plural LED lamps in the chamber and a cord groove formed in a rear surface.

Then the automobile compound taillight can show distinct light signals for braking, a running direction, and the tail of the automobile, and can be repaired easily
