Abstract

Provided is a light emitting diode (LED) package including a phosphor substrate; an LED chip mounted on the phosphor substrate; a circuit board mounted on the other region of the phosphor substrate excluding the region where the LED chip is mounted; an electrode connection portion for electrically connecting the LED chip and the circuit board; and a sealing member that covers the LED chip, the circuit board, and the phosphor substrate.

Claims (14)

1. A light emitting diode (LED) package comprising:

a phosphor substrate having a phosphor;

an LED chip mounted on a surface of the phosphor substrate;

a circuit board mounted on only an other region of the surface of the phosphor substrate excluding a region—in which the LED chip is mounted, the circuit board having a pair of electrodes formed thereon, the pair of electrodes being disposed on the surface of the phosphor substrate at both ends thereof;

an electrode connection portion for electrically connecting the LED chip and the electrodes of the circuit board; and

a sealing member formed on the surface of the phosphor substrate, the sealing member covering the LED chip, the circuit board with the pair of electrodes, and the electrode connection portion, and having side surfaces, each of the pair of electrodes being exposed therethrough,

wherein the sealing member contains a reflective material dispersed therein and light emitted from the LED chip is reflected from the sealing member and passes through the phosphor substrate, and

wherein the side surfaces of the sealing member are respectively coplanar with each of the exposed surfaces of the electrodes and both ends of the phosphor substrate.

2. The LED package according to claim 1 , wherein the phosphor substrate is a glass substrate having phosphor contained therein.

3. The LED package according to claim 1 , wherein the phosphor substrate is a glass substrate coated with phosphor.

4. The LED package according to claim 1 , wherein the electrode connection portion is formed of wire.

5. The LED package according to claim 1 , wherein the sealing member is formed of at least one of transparent epoxy and silicon.

6. The LED package according to claim 1 , wherein the circuit board is a ceramic substrate having one or more pairs of electrodes formed therein.

7. The LED package according to claim 1 , wherein the pair of electrodes has direct contact with the surface of the phosphor substrate.
