Abstract
An illumination apparatus includes a laser diode and an encapsulation layer located at one side of the laser diode. A plurality of fluorescent powders is mixed in the encapsulation layer. A reflecting layer is provided. Light generated by a mixture of light generated by the laser diode and light generated by the fluorescent powders by excitation of the light generated by the laser diode has a part radiating out of the encapsulation layer after it is reflected by the reflecting layer.

An illumination apparatus, comprising:
- a laser diode;
- and
- an encapsulation layer located at one side of the laser diode;
- a plurality of fluorescent powders mixed in the encapsulation layer;
- and
- a reflecting layer;
- wherein first light generated by the laser diode has a first color, the first light enters the encapsulation layer to excite the fluorescent powders to generate a second light having a second color, the first light mixes with the second light to generate a third light having a third color, the third light has a part directly radiating out of the encapsulation layer and another part radiating out of the encapsulation layer after being reflected by the reflecting layer.
