The invention provides a fiber light guiding type vehicle lamp, comprising a plurality of light source modules for providing a light source, a plurality of optical fibers with one end coupled with thelight source modules respectively to enable the light source provided by the light source modules to be transferred through optical fibers, a collecting groove body which is a hollow grooved tube andhas an inner wall with light refection, comprising a plurality of slotted holes which penetrate and are formed on the surface layer of the collecting groove body for coupling the other end of each optical fiber so that the light source can be introduced into the collecting groove body; and a notch which is formed on one end of the hollow grooved tube in a particular section shape and enables a beam in a particular distributed shape to emit through the notch, wherein, the beam in the particular distributed shape corresponds to the particular section shape. The fiber light guiding type vehiclelamp can acquire required light-shape distributed output light, achieve evenness with a certain layer degree, and overcome the problem of poor heat dissipation.
Description
technical field [0001] The invention relates to an optical fiber light guiding type vehicle lamp. Background technique [0002] Traditional automobile and motorcycle lights use a high-brightness light source, such as an HID light source, with optical components such as lenses and reflectors to achieve lighting or indication functions. [0003] In order to meet the needs of environmental protection and energy saving, automobile and motorcycle lights are gradually using LED as their lighting or indicating light source. Due to the limitation that the brightness of a single LED cannot meet the needs of automotive lighting, LEDs are currently used for indication, such as brake lights for automobiles and motorcycles. However, in terms of lighting for automobiles and motorcycles, some leading products have gradually begun to appear. Since the brightness and lighting range that a single LED can produce cannot meet the current lighting requirements of automobiles and motorcycles, t...
