A new type of led car side turn signal

Abstract

The invention discloses a novel light-emitting diode (LED) automobile side turning lamp. The novel LED automobile side turning lamp comprises a lamp housing body, a lens and a circuit board component and is characterized in that the circuit board component is arranged on the lamp housing body and comprises two LEDs; each LED is slantways fixed through a bracket, so that the optical axis direction of the LED and the X axis of an automobile body form a 30-degree included angle; refractive racks for adjusting a light path and frosted grains are arranged on the inner surface of the lens, so that rays emitted by the LED are uniformly distributed in a range of an included angle which is of 5 to 60 degrees and formed by the rear part of the automobile and the X axis of the automobile body; and the lamp housing body is made of acrylonitrile butadiene styrene (ABS). The novel LED automobile side turning lamp is simple in structure and easy to assemble, utilizes the characteristics of an LED cold light source and completely solves the problem that water spray exists in the automobile side turning lamp with narrow volume, and the lamp housing is made of the low temperature resistance ABS material, so that the cost of the whole lamp is reduced wholly.

Description

technical field [0001] The invention relates to the field of automobile lamps, in particular to a novel LED automobile side turn signal. Background technique [0002] At present, traditional car side turn signals use white woven bulbs as the light source. Because the volume of the lamp is usually small, the heat inside the lamp is very high when it is working, so the light distribution mirror and the lamp housing are generally made of heat-resistant and tough polymer. Carbonate (Polycarbonate) PC material. However, one of the biggest problems or defects in it is: when the lamp is turned on for a period of time and then turned off, the temperature inside the lamp is relatively high, while the temperature outside the lamp is low. Cold air and its moisture will be sucked into the lamp chamber from tiny gaps such as wire harnesses and sealing rings, and finally condense on the inner surface of the photodistribution mirror to form water mist in the lamp. In the case of high air ...

Problems solved by technology

However, one of the biggest problems or defects in it is: when the lamp is turned on for a period of time and then turned off, the temperature inside the lamp is relatively high, while the temperature outside the lamp is low. Cold air and its moisture will be sucked into the lamp chamber from tiny gaps such as wire harnesses and sealing rings, and finally condense on the inner surface of the photodistribution mirror to form water mist in the lamp. In the case of high air humidity, it will even form The drops of water will be considered by some users as water leakage and complain to the 4S store for replacement. More importantly, it will affect the driver's recognition of the steering of the vehicle in front, which may cause traffic safety accidents.
