Abstract

A warning light used in lane change of a vehicle is provided, in which the light is installed in a side of a rearview mirror housing where the rearview mirror is connected to the vehicle, or the lights are installed in the two sides of the two front doors of the vehicle, so that the lighting emitted by the light is deflected or directed at the driver'"'"'s eyes in the vehicle. The warning light includes a housing, a light guide, at least one LED light, a circuit board and a mask which is sealed by mold welding disposed on a side of the housing. There are cavities arranged in the rearview mirror or the two sides of the vehicle'"'"'s two front doors where the light is inserted and is detachably installed in the cavity. A prism in the light guide deflects and directs the emitted light toward the driver'"'"'s eyes.

Claims

1. A rearview mirror comprising:

a mirror housing adapted to secure to a vehicle, the mirror housing having an inner side proximal to a front door of the vehicle;

a mirror within the mirror housing positioned to face rearward with the mirror housing;

a warning light comprised of at least one LED within a cavity on the inner side in the mirror housing;

a light guide having an angle of prism to a luminance surface remote from the warning light that deflects light emission from the warning light from an incident optical angle towards the eye of a driver in the vehicle, the light guide being positioned in the cavity and between the warning light and the inner side of the mirror housing used in lane change of a vehicle, the light guide having a shape formed by a frustum and a cylinder connected to an end of the frustum having a larger diameter, wherein the cylinder has a slope through which light is transmitted; and

a mask which is sealed by mold welding disposed on the inner side of the mirror housing, the light guide is disposed on an-area between the mask and the at least one LED light, so that the lighting emitted by the warning light is deflected toward the driver'"'"'s eyes in the vehicle through the mask.

2. The rearview mirror according to claim 1, wherein the warning light further comprises a circuit board, the at least one LED light is arranged on the circuit board.

3. The rearview mirror according to claim 1, wherein the mask is a transparent mask or a semi-transparent mask.

4. The rearview mirror according to claim 1, wherein the warning light is detachably installed in the mirror housing.

5. The rearview mirror according to claim 1, wherein the rearview mirror is connected to the vehicle by bolts.

6. A warning device used in lane change of a vehicle comprising:

a warning light formed with at least one LED;

a set of housings each housing containing a light guide having an angle of prism to a luminance surface remote from the warning light that deflects light emission from the warning light from an incident optical angle towards the eye of a driver in the vehicle, where one of each of the housings is installed in a set of cavities, the set of cavities present on interior surfaces on both of a pair of front doors of the vehicle;

where the light guide has a shape formed by a frustum and a cylinder connected to an end of the frustum having a larger diameter, wherein the cylinder has a slope through which light is transmitted; and

a mask which is sealed by mold welding disposed on an outward face of each housing of the set of housings, the light guide is disposed on an area between the mask and the at least one LED light, so that the lighting emitted by the warning light is deflected toward the driver'"'"'s eyes in the vehicle through the mask.

7. The warning device according to claim 6, wherein the warning light further comprises a circuit board, the at least one LED light is arranged on the circuit board.

8. The warning device according to claim 6, wherein the mask is a transparent mask or a semi-transparent mask.

9. The warning device according to claim 6, wherein the warning device is detachably installed in each of the set of cavities cavity.

10. The warning device according to claim 6, wherein the warning device is connected to the vehicle by bolts.
