Modular microstructure light guide device

Abstract

The invention provides a modularized microstructure light guiding device which is composed of at least one microstructure light guiding unit. Each microstructure light guiding unit comprises a light source, an optical coupling element enabling the light source to emit light in parallel, and a light guiding body comprising at least two incident surfaces, a microstructure light uniformizing area, a total reflection area and an emitting surface, wherein the two incident surfaces guide light rays to the microstructure light uniformizing area and the total reflection area, and then the light rays are reflected and emitted from the emitting surface.

Description

technical field [0001] The invention relates to a technology of a light guide lamp, in particular to a modularized microstructure light guide device applied to a vehicle light guide system. Background technique [0002] When driving at night, due to the high directivity of the LED light source, passers-by will feel the bright spots one by one and have a dazzling feeling. The visual experience for people is similar, and there will not be too many differences. However, with the trend of beautiful vehicle design, in addition to providing safety lighting and warning functions, whether the visual effect of lamps and lanterns is easy to attract attention has become a necessary consideration in the design of car manufacturers. Therefore, the light guide technology for vehicles has evolved from flat effects to 2D or even 2.5 D's visual effects. At present, most of the design methods of LED daytime running lights on the market are lens-type and reflective-type designs. However, to a...

Problems solved by technology

[0003] Most of the prior art or existing light guide devices are large-area light guide bodies or long light guide strips, mainly by placing light sources at both ends of the light guide element or arranging multiple LED light sources under the light guide strip, thereby achieving uniformity. Luminous visual effects, but this kind of practice will result in high demand for overall product manufacturing technology, and the large number of light sources will increase the cost

In addition, the exterior shape and structure design of most lamps are determined by the original factory, so the structure of the light guide device must be provided by the original factory together with the lamp, and the degree of freedom in the application of the light guide device is low.
