Abstract

A direction indication light installed on a handle of a car door comprises a body; a front edge thereof installed with a receiving groove; the receiving groove received with a plurality of circuit boards, a light guide plate, and a cover; each circuit board being installed with light emitting body; upper sides of the circuit boards being installed with a light guide plate for receiving the circuit boards; the power wires of the circuit boards serve to light up the light emitting body of at least one of the circuit boards. By the indication light, the periphery of the car is lighted up so that cars at the periphery of the car can keep attention to the state of the car to prevent from collision due to weak view.

Claims

1. A direction indication light installed on a handle of a car door comprising:

a body;

a front edge thereof installed with a receiving groove;

the receiving groove received with three circuit boards, a light guide plate, and a cover;

each circuit board being installed with light emitting body;

each of the circuit boards being extended with a respective power wire which can be received in a wire guiding trench;

the wires being installed along the wire guiding trench to pass through the hole of the receiving groove so that the wires extends out of the body;

a light guide plate being installed at upper sides of the circuit boards for receiving the circuit boards;

a cover installed at a front end of the light guide plate;

the power wires of the circuit boards for lighting up the light emitting body of at least one of the circuit boards;

if the direction indicating light is switched, the light emitting body of at least one of the circuit boards will extinguish, and the light emitting bodies of the other circuit board light up which are flashed with the indicating light;

thereby the periphery of the car is lighted up so that cars at the periphery of the car can keep attention to the state of the car to prevent from collision due to weak view;

wherein a strip like via hole is formed on the cover;

a plurality of hooks are installed on the cover;

the hooks penetrates through the via holes to hook the end surface of the light guide plate;

the strip like via hole in the cover receives the protruding seat of the light guide plate so that the outer surface of the protruding seat is flushed with the outer surface of the cover;

wherein the receiving groove is installed with a B platform;

an end surface of the B platform is adhered with a B circuit board;

two opposite sides of the B platform are installed with respective A platform;

each A platform is adhered with a respective A circuit board;

wherein the two A platform is separated from the B platform and there are only three platforms for receiving all the circuit boards;

wherein an outside of the light guide plate is protruded with a protruding seat and via holes;

a periphery of the light guide plate are formed with a plurality of screw holes; and

wherein an inner side of the protruding seat is formed with a receiving chamber and each of two sides of the receiving chamber are formed with a recess;

the receiving chamber serves to receive the B circuit board and the recesses serve to receive the A circuit boards;

wherein a size of the receiving chamber is greater than a size of each of the recess;

each of the receiving chamber and the recesses has an approximately rectangular shape; and

all the light emitting bodies is received in the two recesses and the receiving chamber.

2. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein the receiving groove is formed with a plurality of screw holes, a wire guiding trench and a hole.

3. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein a light guide layer is installed in the receiving chamber so that a little light will make the light guide plate light up sufficiently.

4. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein screw holes of the light guide plate are locked to the screw holes of the body so that the light guide plate is assembled to the body.

5. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein a strip like via hole in the cover serves to receive the protruding seat of the light guide plate so that the outer surface of the protruding seat is protruded from the outer surface of the cover.

6. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein an outer surface of the cover and an outer surface of the cover have streamline shapes.

7. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein the positions of the circuit boards are changeable.

8. The direction indication light installed on a handle of a car door as claimed in claim 1, wherein the light emitting bodies of the circuit boards are different or identical.
