    摘要: An omni-directional LED device is constructed such that light is prevented from exiting from the top of the LED device. In one embodiment, an opaque barrier is created and in some embodiments enhancement surfaces are created below the opaque barrier to increase lumen output from the device sides. In one embodiment, a reflecting structure is created to assist with horizontal light mixing. The horizontally mixed light is then redirected through a structure, such as an LED structure, to create a high lumen output, slender back-lighted display.

    摘要: A light source and method for making the same are disclosed. The light source includes a plurality of LEDs mounted on a substrate and a sensor for measuring light from the LEDs. Each LED emits light having a different spectrum from the other LEDs, the average intensity of light from that LED being determined by a drive signal coupled to that LED. The sensor generates a plurality of signals, each signal being characterized by a sensor value that is proportional to the intensity of light emitted by a corresponding one of the LEDs. A controller generates the drive signals and stores a current target value for each LED. The drive signals for each of the LEDs is generated such that the sensor value for that LED matches the stored current target value for that LED.

    摘要: A light source that generates light that is perceived to have a predetermined color is disclosed. The light source includes first and second red LEDs and a non-red light emitter. The first and second red LEDs emit light in the red portion of the spectrum but at different wavelengths. The non-red light emitter emits light at a wavelength in a non-red portion of the spectrum. A controller varies the intensity of the first and second red LEDs to provide a combined light signal that is perceived as having the predetermined color. In one embodiment, the non-red light emitter includes a fluorescent light, and the controller adjusts the intensities of the red LEDs to provide a source that is perceived as an incandescent source of a predetermined color temperature.

    摘要: A system and method for generating white light involves using a combination of white, red, green, and blue LEDs to produce white light and adjusting the emitted light in response to feedback signals. A light system has a light source that includes at least one white LED and multiple color LEDs and a spectral feedback control system configured to detect light that is output from the light source and to adjust the light that is output from the light source in response to the light detection. The spectral feedback control system may include a color sensor configured to provide color-specific feedback signals, a controller configured to generate color-specific control signals in response to the color-specific feedback signals, and a driver configured to generate color-specific drive signals in response to the color-specific control signals.

    摘要: A lighting apparatus having wavelength-converting materials formed in a carrier layer is disclosed. In one embodiment, the lighting apparatus has a light source attached to a substrate that is assembled in a housing. The light source is configured to emit a substantially narrow band light that is transformed into broad-spectrum white light by the wavelength-converting materials positioned on the carrier layer. The wavelength-converting materials and the carrier layer are distanced away from the light source, such that the carrier layer is thermally isolated from the light source.
