Abstract

The invention discloses a light guide band for achieving directional lighting and an optical system for achieving functional multiplexing thereof. The light guide band comprises a condenser at a lightinlet end and an optical pattern surface on the light guide band, wherein the optical pattern surface comprises an optical pattern surface I, an optical pattern surface II and an optical pattern surface III, light emitted by a light guide band light source arranged at the front end of the light guide band condenser is collimated by the condenser and totally reflected in the light guide band, thelight sequentially enters the optical pattern surface I for reflection, the residual light is transmitted to the optical pattern surface II for reflection, at the moment, the residual light is transmitted to the optical pattern surface III for reflection, the three times of reflection are in the driving direction, three optical pattern surface group areas are sequentially lightened, and three directional arrows are lightened; the optical system comprises the light guide band light source, the light guide band, a light reflection bowl light source and a light source downward type light reflection bowl, wherein each light reflection bowl is positioned behind an area without an optical pattern surface of the light guide band, and functional multiplexing of the light guide band light source and the light reflection bowl light source is achieved by adopting different LEDs.

Description

technical field [0001] The invention relates to the field of automobile signal lamps, in particular to a light guide strip for realizing directional lighting and an optical system for realizing function multiplexing. Background technique [0002] In the 21st century, technological development is advancing by leaps and bounds, and automobile lamp technology is also developing continuously. The design of headlights plays a very important role in the styling of the vehicle. All major OEMs hope that the signal lights of the headlights can not only meet the functional requirements, but also have a more fashionable and changeable shape. [0003] At present, the shape of signal lights on the market is generally strip or round or square, which is realized by means of light guides, reflective bowls or thick-walled light guides. The width is generally not large, and the novelty of the shape is low. [0004] In view of the above problems, new design ideas, such as the combination of ...
