Abstract

An LED module includes a heat sink. The heat sink has a mounting surface that defines, with respect to ambient light incident thereon, one main direction of a beam perpendicular to the mounting surface and secondary directions of the beam inclined to the main direction of the beam at angles having absolute values smaller than or equal to 90 degrees. The heat sink also has a reflection surface oriented such that, with respect to the ambient light incident on thereon, a main direction of the beam of the reflection surface is perpendicular to the reflection surface and points in a direction included in the angle range determined by the main direction of the beam of the mounting surface and the secondary directions of the beam of the mounting surface. The LED module further includes an LED light source on the mounting face and pigments on the reflection surface.
