20090108269 | ILLUMINATION DEVICE HAVING ONE OR MORE LUMIPHORS, AND METHODS OF FABRICATING SAME - A light emitter comprising a monolithic die comprising at least one solid state light emitting device and at least a first lumiphor covering part of a light emission region of the die. In some embodiments, at least a second lumiphor is provided on the die. The first lumiphor can be part of a first pattern of lumiphors, and/or the second lumiphor can be part of a second pattern of lumiphors. The first and second lumiphors can differ in luminescent material, size, shape and/or concentration of luminescent material. The lumiphors can overlap completely, partially, or not at all. Some embodiments comprise an electrical interconnection to electrically connect respective solid state light emitting devices. Also, a light emitter comprising unit cells each comprising a group of light emitting devices and at least one lumiphor. Methods of fabricating light emitters comprise selectively applying at least one lumiphor to a monolithic die. | 04-30-2009 |
20090021139 | LIGHTING DEVICE - Lighting devices comprising first and second solid state light emitters and an optical device (e.g., optical fiber). If the emitters are illuminated, ( | 01-22-2009 |
20080259589 | LIGHTING DEVICES, METHODS OF LIGHTING, LIGHT FILTERS AND METHODS OF FILTERING LIGHT - A lighting device comprising a white light source, a filter which filters blue light from the white light, and a second light source which emits red light and/or reddish-orange light. In some embodiments, the white light source comprises a solid state light emitter. A method of lighting, comprising illuminating a white light source, illuminating a red and/or reddish-orange light source, the light sources being positioned and oriented such that the light mixes, and filtering blue light from the mixed light. A method of lighting, comprising illuminating a white light source, filtering blue light from the white light, and illuminating a red and/or reddish-orange light source. A light filter, comprising a first filter component which has a wall region and a window region, and a second filter component comprising two or more reflection regions. Also, methods of filtering. | 10-23-2008 |
20080211416 | ILLUMINATION DEVICES USING EXTERNALLY INTERCONNECTED ARRAYS OF LIGHT EMITTING DEVICES, AND METHODS OF FABRICATING SAME - A light emitter, comprising light emitting devices mechanically interconnected by a common substrate and an interconnection submount. The light emitting devices are electrically interconnected by the submount to provide an array of serially connected subsets of light emitting devices, each subset comprising at least three light emitting devices electrically connected in parallel. Also, a light emitter comprising first light emitting devices mechanically interconnected by a first common substrate, and second light emitting devices mechanically interconnected by a second common substrate, the first light emitting devices being mechanically and electrically connected to the second light emitting devices. Also, a light emitter comprising mechanically interconnected light emitting devices and means for mechanically and electrically interconnecting the plurality of light emitting devices to provide an array of serially connected subsets of light emitting devices, each subset comprising at least three light emitting devices electrically connected in parallel. Also, methods of fabricating light emitters. | 09-04-2008 |
