Abstract
A light emitting device includes: an LED; a reflecting mirror that reflects light emitted by the LED and radiates the light outside and has a reflecting surface shaped in a paraboloid of revolution; and a light absorptive material that, of the light emitted by the LED, blocks the light beyond a 1/4 beam angle θ from being incident on the reflecting mirror. The LED is provided at a position displaced from a focal point of the paraboloid of revolution.
