Abstract

Disclosed embodiments include a manufacturing method for an LED assembly. Providing a first carrier, wherein several LED chips are formed on the first carrier, and providing a second carrier. Attaching the second carrier to the LED chips and detaching the first carrier from the LED chips but leaving the LED chips on the second carrier.

Claims (20)

1. A method for fabricating an LED assembly, comprising:

providing a first carrier on which a plurality of LED chips is arranged in a pattern;

providing a second carrier comprising a plurality of grooves;

forming a conductive film on the second carrier; and

attaching the plurality of LED chips to the second carrier through the conductive film,

wherein the plurality of grooves is formed on the second carrier before attaching the plurality of LED chips to the second carrier.

2. The fabrication method of claim 1 , wherein the second carrier is a transparent carrier comprising transparent glass or transparent silicon carbide.

3. The fabrication method of claim 1 , wherein the second carrier comprises a first region and a second region defined by the plurality of grooves.

4. The fabrication method of claim 3 , further comprising a first circuit formed within the first region.

5. The fabrication method of claim 4 , further comprising a second circuit which is formed within the second region, wherein the first circuit and the second circuit substantially have a same pattern.

6. A method for fabricating an LED assembly, comprising:

providing a first carrier on which a first LED chip and a second LED chip are arranged in a first pattern;

providing a second carrier on which a third LED chip and a fourth LED chip are arranged in a second pattern;

providing a third carrier comprising a plurality of grooves; and

attaching the first LED chip, the second LED chip, the third LED chip, and the fourth LED chip to the third carrier,

wherein the plurality of grooves is formed on the third carrier before the attaching step.

7. The fabrication method of claim 6 , further comprising forming a conductive film on the third carrier.

8. The fabrication method of claim 6 , further comprising dividing the third carrier along the grooves to form an LED assembly having the first LED chip and the second LED chip arranged in the first pattern.

9. The fabrication method of claim 6 , further comprising providing a conductive electrode plate connected to the third carrier.

10. The fabrication method of claim 9 , further comprising providing a bonding wire connecting the electrode plate and the first LED chip.
