LIGHTING MODULE, LIGHT SOURCE UNIT, AND LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide a lighting module having improved light use efficiency by emitting more parallel light from a light source to the outside.

SOLUTION: The lighting module 1 includes a LED 5 provided as the light source on the approximate top of a reflector 4. Around the LED 5, a lens is provided which has a first convex face 61 at the center and a second convex face 62 on the outer periphery of the first convex face 61. The angle of the second convex face 62 is set so that light emitted from the LED 5 through the second convex face 62 is reflected by the reflector 4 and emitted as approximately parallel light to the outside. The angle of the first convex face 61 is set so that light emitted from the LED 5 through the first convex face 61 is emitted as approximately parallel light to the outside in almost the same direction as the approximately parallel light reflected by the reflector 4.
