20130258654 | LED-BASED MR16 REPLACEMENT LAMP - An LED-based lamp can be made to have a form factor compatible with fixtures designed for MR16 lamps. Such a lamp can have a housing that provides an external electrical connection. Inside the housing is disposed a single emitter structure having a substrate with multiple light-emitting diodes (LEDs) arranged thereon. Different LEDs produce light of different colors (or color temperatures). For example, at least one LED can produce a warm white light, while at least one other LED produces a cool white light and at least one other LED produces a red light. A total-internal-reflection (TIR) lens is positioned to collect light emitted from the single emitter structure and adapted to mix the light from the LEDs to produce a uniform white light. A diffusive coating is applied to a front face of the TIR lens for further color mixing. | 10-03-2013 |
20140084796 | TUNING OF EMITTER WITH MULTIPLE LEDS TO A SINGLE COLOR BIN - The color of an LED-based lamp can be tuned to a desired color or color temperature. The lamp can include two or more independently addressable groups of LEDs associated with different colors or color temperatures and a total-internal-reflection (TIR) color-mixing lens to produce light of a uniform color by mixing the light from the different groups of LEDs. The color of the output light is tuned by controllably dividing an input current among the groups of LEDs. Tuning can be performed once, e.g., during manufacture, and the lamp does not require active feedback components for maintaining color temperature. | 03-27-2014 |
20140167075 | PHOSPHOR CAP FOR LED DIE TOP AND LATERAL SURFACES - A method for depositing a layer of phosphor-containing material on a plurality of LED dies includes disposing a template with a plurality of openings on an adhesive tape and disposing each of a plurality of LED dies in one of the plurality of openings of the template. The method also includes forming a patterned dry film photoresist layer over the template and the plurality of LED dies. The photoresist layer has a plurality of openings configured to expose a top surface and side surfaces of each of the LED dies. Next, a phosphor-containing material is disposed on the exposed top surface of each the LED dies. The method further includes removing the photoresist layer and the template. | 06-19-2014 |
20140264402 | PHOSPHORS FOR WARM WHITE EMITTERS - A method for fabricating light-emitting devices includes obtaining a plurality of light-emitting diode (LED) chips fabricated to emit blue light and preparing a phosphor-containing material comprising a matrix material having dispersed therein a mixture of a red phosphor and a green phosphor in a fixed ratio to each other. The method also includes disposing different thicknesses of the phosphor-containing material on different ones of the LED chips. The fixed ratio is chosen such that LED chips having different thicknesses of the phosphor-containing material emit light characterized by different points along the Planckian locus in a CIE chromaticity diagram. | 09-18-2014 |
20140268153 | MANUFACTURING METHOD FOR LED EMITTER WITH HIGH COLOR CONSISTENCY - A method is provided for forming multiple-LED (light-emitting-diode) light emitters from a plurality of LEDs, wherein the number of LEDs in each emitter is an integer M. The method includes providing a plurality of LEDs, each of the LEDs characterized by a first parameter and a second parameter, which are related to color coordinates CIEx and CIEy in a chromaticity diagram. The method also includes determining first and second parameter X | 09-18-2014 |
20140300283 | COLOR TUNABLE LIGHT SOURCE MODULE WITH BRIGHTNESS CONTROL - LED-based light source modules can incorporate color tunability and brightness control, allowing a user to select a desired color temperature and/or brightness and to change either or both dynamically. An emitter can include multiple independently addressable groups of LEDs, each emitting light of a different color. By controlling the relative operating current provided to each group, a desired color temperature can be achieved, and by controlling the absolute operating currents, the brightness of the output light can be controlled. Pulse width modulation (PWM) can be used to control the relative and absolute operating currents. Smooth, gradual transitions between brightness and/or color temperature settings in response to changes can be provided. | 10-09-2014 |
