<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of restraining color variations of light at the time of light-emitting, and to provide a light emission method for restraining color variations of light. <P>SOLUTION: The light-emitting device has a light source 13, a reflector 14 for reflecting the light of the light source 13, and a phosphor sheet 11 for receiving reflective light from the reflector 14 and transmitting the reflective light and emitting light by incidence of the reflective light. Further, the light-emitting device is provided, wherein the light source 13 is located between the reflector 14 and the phosphor sheet 11 and an irradiation direction of the light of the light source 13 faces the direction of the reflector 14 and a reflective surface 15 of the reflector 14 becomes a concave curved surface shape. The light is radiated from the light source 13 to the reflector 14, the light reflected by the reflector 14 is made incident to the phosphor sheet 11 after reflecting the light by the reflector 14 one or more times, and the light transmitting the phosphor sheet 11 and the light emitted by the phosphor sheet are radiated outside. <P>COPYRIGHT: (C)2010,JPO&INPIT |
