Abstract
A light source includes a light emitting diode (LED) packing structure, a fiber and a light color converting portion. An end of the fiber couples with the LED packing structure. The light color converting portion is arranged at an opposite end of the fiber. The light color converting portion contains phosphor therein. Blue light emitted by the LED package transmits to the light color converting portion via the fiber and excites the phosphor to produce yellow light which mixes with the blue light to generate white light. An LED automobile lamp having the light source is also provided.
Claims16
A light source comprising:
- a light emitting diode (LED) packing structure;
- a fiber with one end optically coupling with the LED packing structure;
- and
- a light color converting portion disposed at an opposite end of the fiber, the light color converting portion containing phosphor therein;
- light emitted by the LED packing structure which has a first color transmitting to the light color converting portion and exciting the phosphor to form light having a second color, the light having a first color and the light having a second color mixing together to generate a light having a third color which is for illuminating a surrounding environment of the light source.
A light emitting diode (LED) automobile lamp comprising:
- a light source, the light source comprising
- an LED packing structure;
- a fiber with an end coupling with the LED packing structure;
- and
- a light color converting portion disposed at an opposite end of the fiber, the light color converting portion containing phosphor therein, a first light emitted by the LED packing structure transmitting to the light color converting portion and exciting the phosphor to form a second light, the first light and second light mixing together to form a third light having a color different from that of the first light and that of the second light, the third light being configured for illuminating an external environment of the LED automobile lamp;
- a lens;
- and
- a shading portion, the shading portion being disposed between the light source and the lens, the third light from the light color converting portion being regulated to a preset luminance shape by the shading portion and radiating out via the lens.
