摘要:
A light-emitting device which uses and LED having a light-emitting element being placed on a package substrate. The light-emitting element has a light-extracting surface. A fluorescent element which is formed by dispersing a fluorescent material in a transparent substance and is placed face to face with the light-extracting surface of the light emitting element and comprises a clearance gap in between. The light-emitting element generates light of a certain wavelength that emanates through the light-extracting surface into the fluorescent element where the wavelength is changed. The device further comprises an optical element which receives light from the light-emitting element through the fluorescent element and directs the light to the outside of the device.
