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, comprising:

a metal lamp holder defining a cavity therein, a bottom of the cavity forms a sloping bench configured for the installation of a luminous body thereon, the LED vehicle cornering lamp being configured to turn on the luminous body during vehicle turns;

the luminous body is disposed on the sloping bench inside the cavity of the metal lamp holder, the luminous body connects with a controller configured to operate the luminous body during vehicle turns;

a reflector disposed about the luminous body and configured to collect light from the luminous body and increase illumination in a lateral direction of the vehicle using reflection;

a transparent protection cover engaged in a liquid-tight manner with the metal lamp holder, the metal lamp holder comprises aluminum alloy, wherein the bottom of the cavity has three parallel sloping benches, and the three parallel sloping benches and the metal lamp holder are jointless at a twenty two point five (22.5) degree included angle, a bottom of the metal lamp holder has a plate-shaped heat abstractor.

2. 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.

3. A LED vehicle cornering lamp as set forth in claim 1, 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.

4. A LED vehicle cornering lamp, comprising:

a metal lamp holder defining a cavity therein, a bottom of the cavity forms a sloping bench configured for the installation of a luminous body thereon, the LED vehicle cornering lamp being configured to turn on the luminous body during vehicle turns;
