Abstract:
A thin-type light emitting diode lamp includes a blue light emitting diode chip (6) disposed at a substantial center of an inner bottom surface of a groove-shaped recess (3) formed at an end surface and having a thin elongated rectangular opening, a red light conversion layer (7) covering the blue light emitting diode chip (6) and made of a light-transmitting synthetic resin containing powder of a red fluorescent material which emits red light when excited by blue light emitted from the blue light emitting diode chip, and a green light conversion layer (10) made of a light-transmitting synthetic resin containing powder of a green fluorescent material which emits green light when excited by the blue light. The light emitting diode lamp further includes a light transmitting layer (9) intervening between the red light conversion layer (7) and the green light conversion layer (10). The light transmitting layer contains neither the red fluorescent material nor the green fluorescent material or contains the red fluorescent material or the green fluorescent material only by a small amount.
