Vehicle led linear lighting module

Abstract

A vehicle LED linear lighting module is provided, including at least one printed circuit board, at least one light bar, an optical collimator and a light guide. The light bar is disposed on the printed circuit board and composed of a plurality of light emitting diodes in a linear lighting and arranged with equal pitches. The optical collimator has a first optical surface, a second optical surfaceand a third optical surface, and covers the plurality of light emitting diodes in a full coverage. By using different optical surfaces of the optical collimator and the arrangement of the light incident surface and the light exit surface of the light guide, the light bar can greatly improve the light effect. The lighting module has the effects of high brightness and high uniformity at the same time, can meet the requirement for high light intensity of vehicle lamp light distribution laws and regulations when applied to a vehicle lamp, and can also have an excellent visual effect. And the flexible performance is achieved and applied to vehicle lamps with free curve shapes, so that a vehicle factory can have more diversified creative thinking in designing the shapes of the vehicle lamps.

Description

technical field [0001] The invention relates to an LED vehicle-mounted linear light-emitting module, in particular to a vehicle lamp light-emitting module that is flexible and capable of emitting light in a linear manner, and can be quickly applied to free curves. Background technique [0002] For LED-related lighting technologies, with the development of light-emitting diodes (LEDs) becoming more and more mature, LEDs have more advantages than traditional halogen bulbs, such as: small size, high brightness, low power and long life, etc. Its application is also more and more extensive. At present, in the application of daytime running lights, many car manufacturers use light-emitting diodes as the light source of lamps, from the earliest point light source to the current surface light source, 3D three-dimensional lighting angle and linear light source. However, light-emitting diodes are point light sources with directivity. Directly applied to daytime running lights will ma...
