Abstract

A light emitting device module is provided. The light emitting device module includes a plurality of light emitting devices which are formed adjacent to each other, a plurality of radiating bases which support at least one of the plurality of the light emitting devices, and a heat transfer prevention unit which prevents heat from being conducted between the plurality of the radiating bases, wherein distances between the adjacent light emitting devices are less than mean values of the length along the adjacent direction of the adjacent light emitting devices.

Claims (27)

1. A light emitting device module comprising:

a plurality of light emitting devices which are formed adjacent to each other;

a plurality of radiating bases which support at least one of the plurality of the light emitting devices; and

a heat transfer prevention unit which prevents heat from being conducted between the plurality of the radiating bases,

wherein distances between the adjacent light emitting devices are less than mean values of the length of the light emitting device along the adjacent direction of the adjacent light emitting devices, and

wherein the heat transfer prevention unit comprises a thermal insulator which is formed of a material which has less thermal conductivity than the radiating bases.

2. The light emitting device module of claim 1 , wherein the heat transfer prevention unit further comprises a gap which is formed between adjacent radiating bases, and ventilates an atmosphere around the radiating bases.

3. The light emitting device module of claim 1 , wherein the plurality of radiating bases is formed by a gap which has a + shape, and has a predetermined width and depth on a frame so that the frame is divided into four parts.

4. The light emitting device module of claim 3 , wherein a thermal insulator is formed in the gap which has the + shape.

5. A light emitting device module comprising:

a plurality of light emitting devices which are formed adjacent to each other;

a plurality of radiating bases which support at least one of the plurality of the light emitting devices; and

a heat transfer prevention unit which prevents heat from being conducted between the plurality of the radiating bases,

wherein distances between the adjacent light emitting devices are less than mean values of the length of the light emitting device along the adjacent direction of the adjacent light emitting devices, and

wherein each of the radiating bases comprises:

a main frame which comprises a plurality of through hole parts formed in one diagonal direction with respect to each other, and a plurality of convex parts formed in another diagonal direction with respect to each other, wherein one surface of each of the convex parts is a light emitting device loading surface; and

a nest frame which is formed in each of the through hole parts, wherein one surface of the nest frame is a light emitting device loading surface; and

wherein a gap is formed between the main frame and the nest frame.

6. The light emitting device module of claim 5 , wherein a thermal insulator is formed in the gap.

7. The light emitting device module of claim 6 , wherein, when light emitting devices emit light at different times, each of the light emitting devices which emit light at different times is loaded on the nest frame.

8. The light emitting device module of claim 5 , wherein, when light emitting devices emit light at different times, each of the light emitting devices which emit light at different times is loaded on the nest frame.

9. A light emitting device module comprising:

a plurality of light emitting devices which are formed adjacent to each other;

a plurality of radiating bases which support at least one of the plurality of the light emitting devices; and

a heat transfer prevention unit which prevents heat from being conducted between the plurality of the radiating bases,

wherein distances between the adjacent light emitting devices are less than mean values of the length of the light emitting device along the adjacent direction of the adjacent light emitting devices, and

wherein the radiating bases are loaded on a radiating base supporter, and a heat conductor is formed between each of the radiating bases and the radiating base supporter.
