BRAKE LIGHT SYSTEM AND BRAKE LIGHT

摘要

A braking light system mounted on a road vehicle includes at least one braking light, a power source, a detecting unit, and a controlling unit. The braking light includes a light guide plate, a first light source, and a second light source. The light guide plate includes a first sidewall and a second sidewall and a plurality of holes and depressions to release internal light, the holes are arranged to present a decreasing diameter and decreasing density of holes between the light sources and sidewalls. The controlling unit controls the power source to provide power for the first light source at night, and when the detecting unit detects deceleration, the controlling unit is prompted to further control the power source to provide power for the second light source to emit light to provide an effective visual braking warning to any following driver.

主权项

1. A braking light system being mounted on a road vehicle, comprising:
at least one braking light comprising:
a light guide plate comprising a first sidewall and a second sidewall opposite to the first sidewall and defining a plurality of holes, wherein the diameter of the holes gradually decreases along a direction from the second sidewall to the first sidewall, and the density of the holes gradually decreases along a direction from the second sidewall to the first sidewall;at least one first light source fixed to the first sidewall; andat least one second light source fixed to the second sidewall; a power source electronically connected to the at least one first light source and the at least one second light source;
a detecting unit configured to determine whether the vehicle is decelerating; anda controlling unit configured to control the power source to provide power for the first light source to emit light in response to a user operation, and to control the power source to provide power for the second light source to emit light when the vehicle is decelerating.
