摘要： A light emitting device having a die that includes a light source that generates light of a first wavelength and a layer of phosphor particles covering the die is disclosed. The phosphor particles convert a portion of the light of the first wavelength to light of a second wavelength. The light source can be fabricated by attaching the light source to a substrate, and converting the light source by applying a light converting layer that includes a volatile carrier material and particles of a phosphor that convert light of the first wavelength to light of the second wavelength over the light source. The volatile carrier material is then caused to evaporate leaving a layer of the phosphor particles over the light source. A binder material can be incorporated in the volatile carrier for binding the phosphor particles to one another after the volatile carrier material is evaporated.

摘要： A light source and method for controlling the same is disclosed. The light source includes a first component light source that includes N LEDs, a photo-detector, and a light redirector, where N>1. Each LED has a light emitting chip in a package. The light emitting chip emits light in a forward direction and light in a side direction. The light generated in the forward direction is determined by a drive signal coupled to that LED. A portion of the light in the side direction leaves the package. The light redirector is positioned such that a portion of the light in the side direction that leaves the package of each of the LEDs is scattered onto the photo-detector. The photo-detector generates N intensity signals, each intensity signal having an amplitude related to the intensity of the light emitted in the side direction by a corresponding one of the LEDs.

摘要： A solid state light source having first and second component light sources and an interface circuit and a method for making the same are disclosed. The first and second component light sources emit light having first and second color points on different sides of the black body radiation curve. The first and second component light sources include LEDs that emit light of a first wavelength and a layer of a light converting material that converts a portion of that light to light of a second wavelength. The interface circuit powers the first and second component light sources such that the solid state light source has a color point that is closer to the black body radiation curve than either the first or second color points. A third component light source can be included to expand the range of white color temperatures that can be reached by the light source.

The nanoparticles that are suspended in the encapsulant may be either oxides or non-oxides and may include SiO2, TiO2, Al2O3, ZrO2, Ti, TiB2, TiC, and TiN. The nanoparticles may range in size from 5 to 165 nm in diameter. The encapsulant containing nanoparticles may be used in an electroluminescent device by being deposited in a concave base cavity to cover a light source, such as a light-emitting diode (“LED”), positioned in the concave base cavity, and may also be applied in the form of a conformal coating that covers the light source. An electroluminescent device utilizing the encapsulant containing nanoparticles and a method of producing such a device is also provided.

摘要： A light emitting device has a light emitting diode (LED), a reflector cup, and one or more adjustment mechanisms to control the intensity profile of light emitted from the light emitting device. The reflector cup has a base and a sidewall extending outward from the base. A base adjustment mechanism controls the total amount of light reflected from the base and into the beam of light emitted from the light emitting mechanism by controlling the aggregate reflectivity of the base. A sidewall adjustment mechanism controls the angle of the sidewall relative to the base. A vertical adjustment mechanism vertically raises or lowers the LED relative to the base.
