Description

Technical Field

[0001] The utility model belongs to the field of automotive parts, and particularly relates to an automotive side turn signal lamp. Background Art

[0002] An automotive turn signal lamp refers to a lamp that, when a vehicle turns, warns pedestrians or vehicles in front of or behind the vehicle by turning on the flashing indicator lamp in the corresponding direction to indicate the driving direction of the vehicle. The light-emitting strip of a traditional automotive side turn signal lamp is usually a relatively narrow long strip. For some large vehicles, the narrow light-emitting strip structure has too small a light-emitting area, resulting in a poor warning effect. Currently in the market, to solve this technical problem, the light-emitting strip is simply widened. However, there are still drawbacks such as uneven light and poor brightness. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a wide reflective surface side turn signal lamp with uniform light and good brightness.

[0004] To solve the above problems, the technical solution adopted by the utility model includes: a lamp holder and a light distribution mirror provided at the upper end of the lamp holder. A light source installation cavity is integrally formed at the end of the lamp holder, and an LED lamp circuit board is provided in the light source installation cavity. It is characterized in that: the light distribution mirror is wider at the front and narrower at the rear. A light guide plate is integrally formed at the bottom of the light distribution mirror, and a light-emitting plate is integrally formed at the front end. The light-emitting plate is provided with a first light-emitting surface and a second light-emitting surface arranged at an included angle. V-shaped light refraction grooves are provided at the bottoms of the first light-emitting surface and the second light-emitting surface. The rear end of the light guide plate is thicker than the front end, and an incident light surface is provided at the thicker end.

[0005] The wide reflective surface side turn signal lamp is characterized in that: the incident light surface has a concave light-gathering surface, and the LED lamp on the LED lamp circuit board is aligned with the concave light-gathering surface.

[0006] The wide reflective surface side turn signal lamp is characterized in that: ribs are provided on both sides of the lamp holder on both sides of the light-emitting plate.

[0007] The wide reflective surface side turn signal lamp is characterized in that: a circuit board slot is provided in the light source installation cavity, and positioning ribs for pressing on the LED lamp circuit board are provided on the light distribution mirror.

[0008] The wide reflective surface side turn signal lamp is characterized in that: pin terminals are provided on the LED lamp circuit board, and sockets are provided at the bottom of the light source installation cavity. The pin terminals are inserted into the sockets.

[0009] The wide reflective surface side turn signal lamp is characterized in that: a round hole ear hole plate is provided at the rear end of the lamp holder, and a long hole ear hole plate is provided at the front end.

[0010] The wide reflective surface side turn signal lamp described above is characterized in that the included angle between the first light-emitting surface and the second light-emitting surface is 175°-177°.

[0011] The advantages of the wide reflective surface side turn signal lamp of the present utility model are as follows: while the light-emitting plate is relatively wide, by setting the light distribution lens into a structure that is wider at the front and narrower at the rear, and setting the light guide plate into a structure that is thicker at the rear end than at the front end, the light emitted by the LED lamp circuit board can be emitted from the light-emitting plate more concentratedly, with better brightness. Moreover, the light-emitting plate is provided with a first light-emitting surface and a second light-emitting surface arranged at an included angle, so that the light-emitting angle is larger, the warning range is increased, and the blind area is reduced.
