A thin-type light emitting diode lamp comprises a blue light emitting diode chip (6) disposed at the substantially central portion of the inner bottom face of a trench-type recess (3) disposed in the leading end face and having an opening of a slender rectangle shape, a red light changing layer (7) disposed to cover the blue light emitting diode chip (6) and prepared by mixing the powder of such a red fluorescent material into a light transmitting synthetic resin as is excited with the blue light emitted by the blue light emitting diode chip to emit a red light, and a green light changing layer (10) prepared by mixing the powder of such a green fluorescent material into a light transmitting synthetic resin as is excited with the blue light to emit a green light. A light transmitting layer (9) containing either none of the red light fluorescent material and the green light fluorescent material or little is disposed between the red light changing layer (7) and the green light changing layer (10). |
