Abstract

The invention discloses a LED vehicle cornering lamp, including a metal lamp holder, wherein the metal lamp holder is equipped with inward cavity, and in the bottom of the cavity has a sloping bench for the installation of the luminous body, which is to turn the luminous body into the lateral directions during steering maneuvers; a LED luminous body at least, which is installed in the sloping bench inside the cavity of the metal lamp holder, wherein the luminous body connects with a controller while the controller controls the make-and-break of the LED luminous body; a reflector corresponding to the luminous body, wherein the reflector collects the light from the LED luminous body and lightens the lateral direction of the vehicle after reflection; a transparent protection cover, wherein the protection cover is liquid-tight assorted with the metal lamp holder port. The LED vehicle cornering lamp of the invention could be easily installed in the front of the vehicle, and lighten the road of lateral directions by using the auxiliary lamp installed in forward direction by the sloping bench inside the metal lamp holder, so as to decrease the blind area when changing directions during the night and enhance the safety when driving at night; furthermore, the utility mode has merits with simple structure, low cost and is suitable to be universalized in all vehicles.

Claims

1. A LED vehicle cornering lamp, including:

A metal lamp holder, wherein the metal lamp holder is equipped with inward cavity, and in the bottom of the cavity has a sloping bench for the installation of the luminous body, which is to turn the luminous body into the lateral directions during steering maneuvers;

A LED luminous body at least, which is installed in the sloping bench inside the cavity of the metal lamp holder, wherein the luminous body connects with a controller while the controller controls the make-and-break of the LED luminous body;

A reflector corresponding to the luminous body wherein the reflector collects the light from the LED luminous body and lightens the lateral direction of the vehicle after reflection;

Transparent protections cover, wherein the protection cover is liquid-tight assorted with the metal lamp holder port.

2. A LED vehicle cornering lamp as set forth in claim 1, characterized in that the controller includes a processor and an angular velocity sensor, wherein the angular velocity sensor detects the angular velocity signal of vehicle steering, and transmits the signal to LED drive circuits to control the make-and-break of the LED luminous body.

3. A LED vehicle cornering lamp as set forth in claim 1, characterized in that the reflector has a corresponding inner lens hood to prevent the reversion of the light from the LED luminous body.

4. A LED vehicle cornering lamp as set forth in claim 1, characterized in that the metal lamp holder is made by the aluminum alloy, wherein the bottom of cavity has three parallel sloping benches, and the sloping benches and the metal lamp holder are jointless at 22.5 degree included angle, while in the bottom of the metal lamp holder has a plate-shaped heat abstractor.

5. A LED vehicle cornering lamp as set forth in claim 4, characterized in that there are three luminous body, which are installed in three sloping bench separately, and are powered by the drive circuit board insider the cavity of the metal lamp holder, illuminating thereof.

6. A LED vehicle cornering lamp as set forth in claim 1, characterized in that the transparent protections cover has a flat transparent part, a fixed part which is located in both ends of the flat transparent part and corresponding to the shape of the head face of the metal lamp holder, and a circular orientation sealing part which is embedded in the port of the cavity of the metal lamp holder, wherein the transparent protection cover is fixed joint with the metal lamp holder by the through hold in the fixed part and the bolt that penetrated through the hole.

7. A LED vehicle cornering lamp as set forth in claim 6, characterized in that the orientation sealing part has circular groove to hold the sealing ring, wherein the sealing right is located in the circular groove and has a liquid-tight manner connection with the inner surface of the cavity of the metal lamp holder.

8. A LED vehicle cornering lamp as set forth in claim 1, characterized in that both sides and the rear of the metal lamp holder has clamps separately in order to easily install the LED vehicle cornering lamp into the vehicle.

9. A LED vehicle cornering lamp as set forth in claim 1, characterized in that the metal lamp holder has a through hole in the side near to the drive circuit board, and a water-proof cable joint box is located in the through hold and liquid-tightly connected with the metal lamp holder.
