| titleOfInvention | A kind of LED chip and preparation method thereof |
| abstract | Disclosed herein a kind of LED chip and manufacture method thereof, the manufacture method of described LED chip, epitaxial loayer is formed in the one side of Sapphire Substrate, the another side of described Sapphire Substrate is formed the terrace with edge of array arrangement, and the one side being formed with terrace with edge in described Sapphire Substrate forms reflector.Change the shooting angle of light on LED chip surface by the secondary reflection on reflector like this, the exiting surface of reflector and LED cannot form waveguiding structure, reduces total reflection probability, thus reaches the object improving light eduction rate. |
