<p>A primary light source (12) is configured from a white LED, and includes an LED chip (12c), a resin (12r) and a package (12p). The LED chip (12c) is configured from, for example, a blue LED and emits blue light (L_b). The resin (12r) contains a powdered fluorescent substance that is excited by the blue light (L_b) and emits fluorescent light (LF_y). In addition, the resin (12r) diffuses the blue light (L_b) and emits this light from a light-emitting region (S). A secondary light source (22) is configured from a violet LED, and emits violet light (L_v) to the light-emitting region (S). The resin (12r) reflects and diffuses the violet light (L_v).</p> |
