Title:
LIGHT EMITTING DEVICE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2008192909
Kind Code:
A
Abstract:

To provide a light emitting device having a uniform phosphor layer in a position detached from an LED chip, and to provide a method of manufacturing the device.

The light emitting device has a light emitting element 2, a translucent layer 9 and the phosphor layer 7. A transparent conductive film 10 is arranged between the translucent layer 9 and the phosphor layer 7. Thus, the phosphor layer 7 can be formed by an electrodeposition process with the transparent conductive film 10 as an electrode. Thus, the uniform phosphor layer 7 can easily be formed in the position detached from the light emitting element 2. A rise temperature of the phosphor layer when using the light emitting device can be prevented by thermal conductivity of the transparent conductive film 10.
