LIGHT EMISSION DEVICE

摘要

A light emission device having high illumination intensity and longer service life. The light emission device (10) includes a concave mirror (12) having a light reflection surface (20) on its inner side and LED light sources (26a, 26b) contained in the concave mirror (12). The light reflection surface (20) is radially split into split regions (S) along the center axis (L) of the concave mirror (12), partially ellipsoidal surfaces (20a, 20b) each formed by cutting a part of a spheroidal surface are respectively formed in the split regions (S), and the LED light sources (26a, 26b) are disposed at the focal points (Fa,Fb) of corresponding partially ellipsoidal surfaces (20a, 20b) so as to face the corresponding partially ellipsoidal surfaces (20a, 20b).
