20110249467 | LIGHT EMITTING DEVICE CREATING DECORATIVE LIGHT EFFECTS IN A LUMINAIRE - The present invention relates to a light emitting device ( | 10-13-2011 |
20110267835 | LIGHT SOURCE - 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 reflector comprises at least one transmitting portion being arranged such that at least a portion of light incident on the at least one transmitting portion is transmitted through the reflector, for example a through hole extending along an axis, allowing for an almost viewing angle independent light intensity of the light source. | 11-03-2011 |
20110267836 | LIGHT SOURCE - 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. | 11-03-2011 |

20130094240 | ILLUMINATION DEVICE WITH WAVEGUIDE AND LEDS - The invention relates to an illumination device ( | 04-18-2013 |
20130201690 | Illumination device and luminaire - Today the use of false ceilings is decreasing as it involves too high an energy consumption. The tendency nowadays is to have bare concrete ceilings onto which luminaires are mounted, which often causes acoustical problems. The invention deals with these acoustical problems and relates to an illumination device ( | 08-08-2013 |
20130336001 | Free form lighting module - The invention provides an illumination device comprising a waveguide having a first face, a second face, and a waveguide edge. The device further comprises a LED light source, wherein the LED light source is arranged to couple at least part of the light source light into the waveguide element. The device also comprises a first transmissive reflector, arranged at the first face side, and a second transmissive reflector, arranged at the second face side. The LED light source, the waveguide, the first transmissive reflector, and the second transmissive reflector, are arranged to generate the first and second light in a direction away from the first face and in a direction away from the second face, respectively. Such an illumination device may allow lighting of a room, for instance via the ceiling with uplight, and lighting of a specific area in the room with downlight. | 12-19-2013 |
