Abstract
An LED module includes an LED and a light-guiding board. The light-guiding board includes a light-incident face facing the LED, a light-emergent face, a light-reflecting face opposite to the light-emergent face, and a light-converting layer containing phosphors therein. Light emitted from the LED sequentially moves the light-incident face, the light-converting layer and the light-emergent face to leave the light-guiding board. The light-converting layer has a uniform thickness.

An LED module, comprising:
- an LED for emitting light;
- and
- a light-guiding board comprising a light-incident face facing the LED and receiving light from the LED, a light-emergent face for exit of the light from the light-guiding board, and a light-converting layer containing phosphors therein, the light which enters the light-guiding board exiting the light-emergent face after moving through the light-converting layer, wherein the light-converting layer is excited by the light to generate another light with a different wavelength, a mixture of the light and the another light generating a third light having a color different from those of the light and the another light.
