AI Technical Summary

Technical Problem

The existing turn signals have small light sources, uneven brightness, and weak warning effect, which makes it difficult to effectively remind vehicles or pedestrians behind when turning, increasing traffic safety hazards.

Method used

It adopts a combination structure of turn signal reflector and light guide plate, and utilizes the different angle designs of the main light guide plate, inner light guide plate and outer light guide plate to expand the light diffusion range through multiple refractions, transforming the point light source into a surface light source, thereby improving brightness uniformity and warning level.

Benefits of technology

It improves the uniformity of turn signal brightness, resulting in a more balanced light distribution, enhanced signal recognition and warning effect, and reduced traffic safety hazards.

Abstract

The steering lamp assembly with the uniform brightness and the high safety coefficient comprises a steering lamp bowl and a steering lamp light guide plate on the front side, and the steering lamp bowl is provided with a steering lamp hole used for installing a steering lamp; the steering lamp light guide plate is provided with a main light guide plate part facing the steering lamp hole, and an inner light guide plate part and an outer light guide plate part which are located on the left side and the right side of the main light guide plate part respectively and bent inwards. The included angle between the inner light guide plate part and the main light guide plate part is an acute angle, and the included angle between the outer light guide plate part and the main light guide plate part is an obtuse angle; the inner side of the steering lamp light guide plate is provided with a light guide ridge, and the outer bottom is provided with an inner sinking step part. The main light guide plate is matched with the inner acute-angle light guide plate part and the outer obtuse-angle light guide plate part, the light diffusion range is expanded through refraction at different angles, and central bright spots or edge dark areas of a traditional steering lamp are avoided. The transverse ribs of the main light guide plate cooperate with the gradually-changed width ribs of the inner / outer light guide plate, so that the light is uniformly emitted after being refracted for multiple times, the brightness distribution is more balanced, and the signal identification degree is improved.
