| 20090283779 | LIGHT SOURCE WITH NEAR FIELD MIXING - A light emitting diode (LED) component comprising a submount with an array of LED chips and a lens over the array of LED chips. A diffuser is arranged so that at least some light from the LEDs passes through the diffuser to mix the LED light in the near field. The light passing through the diffuser appears as a mixture of LED chip light when directly viewed. A lighting device is also disclosed comprising an LED component comprising an array of LED chips and a near field diffuser to mix at least some of the light from the LED chips in the near field. A remote reflector is included to reflect at least some the light from the LED component so that is emits from the lighting device in the desired direction. | 11-19-2009 |
| 20100103660 | Array layout for color mixing - Lamps, luminaries or solid state lighting components are disclosed having multiple discrete light sources whose light combines to provide the desired emission characteristics. The discrete light sources are arranged in an array pursuant to certain guidelines to promote mixing of light from light sources emitting different colors of light. One embodiment solid state lighting component comprises a light emitting diode (LED) component having an array of LED chips having a first group of LED chips and one or more additional groups of LED chips. The array is arranged so that no two LED chips from said first group are directly next to one another in the array, that less than fifty percent (50%) of the LED chips in the first group of LEDs is on the perimeter of the array, and at least three LED chips from the one or more additional groups is adjacent each of the LED chips in the first group. | 04-29-2010 |
| 20100127283 | ARRAY LAYOUT FOR COLOR MIXING - Solid state lighting components are disclosed having multiple discrete light sources whose light combines to provide the desired emission characteristics. One embodiment of an LED component according to the present invention comprises a rectangular submount. A first group of blue shifted yellow (BSY) LED chips, a second group of BSY LED chips and a group of red LED chips are mounted on the submount. A plurality of contacts is arranged along one of the edges of the submount and accessible from one side of the component for applying electrical signals to the groups of LED chips. | 05-27-2010 |
| 20100254129 | SATURATED YELLOW PHOSPHOR CONVERTED LED AND BLUE CONVERTED RED LED - SSL lamps or luminaires are disclosed that combine blue, yellow (or green) and red photons or emissions to generate light with the desired characteristics. In different embodiments according to the present invention, the blue emission is not provided by an LED chip or package having a blue LED coated with a yellow phosphor, with blue light leaking through the yellow phosphor. Instead, the blue light component can be provided by other types of LED chips in the SSL luminaire such as one having a blue LED covered by a different colored conversion material, with blue light from the blue LED leaking through the different colored conversion material. In one embodiment, the blue component can be provided by an LED chip comprising a blue emitting LED covered by a conversion material that absorbs blue light and re-emits red light, with a portion of the blue light from the LED leaking through the red conversion material. | 10-07-2010 |
| 20110012143 | SOLID STATE LIGHTING COMPONENT - An LED component comprising an array of LED chips mounted on a planar surface of a submount with the LED chips capable of emitting light in response to an electrical signal. The LED chips comprise respective groups emitting at different colors of light, with each of the groups interconnected in a series circuit. A lens is included over the LED chips. Other embodiments can comprise thermal spreading structures included integral to the submount and arranged to dissipate heat from the LED chips. | 01-20-2011 |
| 20110148327 | HIGH CRI ADJUSTABLE COLOR TEMPERATURE LIGHTING DEVICES - Solid state luminaires and light engines comprising a first group of solid state emitters comprising a first emitter emitting above the black body locus (BBL) in a CIE diagram, and a second emitter emitting below the BBL. The combination of light from the first and second emitters generates an emission color point within a standard deviation of the BBL. A second group of solid state emitters is included, the combination of light from the first and second groups of emitters causes emission within a standard deviation of the black body locus (BBL), wherein varying the intensity of the second group of emitters causes emission from the first and second groups of emitters to vary within a range of color temperatures while still emitting within the standard deviation of the BBL. | 06-23-2011 |
| 20110215699 | SOLID STATE LAMP AND BULB - Solid state lamps and bulbs comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffuser. These are arranged on a heat sink in a manner that allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omni-directional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. Additionally, this arrangement allows aesthetic masking or concealment of the appearance of the conversion regions or layers when the lamp is not illuminated. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs. Embodiments of the invention can be arranged to fit recognized standard size profiles such as those ascribed to commonly used lamps such as incandescent light bulbs, while still providing emission patterns that comply with ENERGY STAR® standards. | 09-08-2011 |
| 20110216523 | NON-UNIFORM DIFFUSER TO SCATTER LIGHT INTO UNIFORM EMISSION PATTERN - A lighting device comprising a light source and a diffuser spaced from the light source. The lighting device further comprises a wavelength conversion material disposed between the light source and the diffuser and spaced from the light source and the diffuser, wherein the diffuser is shaped such that there are different distances between the diffuser and said conversion material at different emission angles. In other embodiments the diffuser includes areas with different diffusing characteristics. Some lamps are arranged to meet A19 and Energy Star lighting standards. | 09-08-2011 |
