LIGHT SOURCE WITH LEDS, LIGHT GUIDE AND REFLECTOR

摘要

The present invention relates to a light emitting diode, LED, light source that may be arranged for retrofitting into a luminaire employing an incandescent light source. The light source comprises a light guide into which light from one or more LEDs in a light unit arranged at one end of the light guide is injected, and a reflector having a reflecting surface arranged at the other end of the light guide and facing towards the light guide capable of reflecting light incident on the reflecting surface. According to the present invention, the reflecting surface can be arranged in a number of exemplary ways such as to enable the light emitted from the light source to have a spatial intensity distribution that is similar to the light intensity distribution of an incandescent light source.
