Abstract

The invention discloses a vehicle-mounted atmosphere lamp based on an LED light source. The lamp comprises a shell and a flexible optical fiber, an LED light source emitter and a light beam collimator are installed in the shell, the light beam collimator is provided with a light outlet, the flexible optical fiber is connected with the light outlet, the flexible optical fiber comprises a coating layer, a middle layer and a core layer, the coating layer wraps the outer part of the middle layer, the middle layer wraps the outer part of the core layer, and a plurality of scattering particles are uniformly arranged in the middle layer. The coupling efficiency of the flexible optical fiber light source is higher, the middle layer of the flexible lamp fiber is doped with a large number of scattering particles, it is guaranteed that the number of times of light refraction is larger, and light can be propagated by a farther distance in the flexible optical fiber.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration, in particular to a vehicle ambient light based on an LED light source. Background technique [0002] At present, one of the mainstream technologies for interior ambient lights is LED light source combined with side-emitting polymer optical fiber (POF). Ordinary optical fiber mainly transmits light from the incident end face of the fiber to the exit end face. Side-emitting polymer optical fiber (POF) is different from this. The main purpose of POF is to transmit part of the light from the outer layer of the fiber to form side-emitting light. Using LED as the light source, the light enters the POF, and the light energy transmitted from the outer layer of the POF turns the LED point light source into a line light source. The disadvantages of polymer optical fiber (POF) are low light source coupling efficiency, uneven light source, and long transmission distance cannot be obta...
