    摘要： A light-emitting diode with an improved service life is provided. The diode is formed from a transparent outer shell that contains a heat-resistant encapsulant at least partially surrounding a light-emitting diode clip. The first encapsulant is compressed between the outer shell and a second encapsulant when it is sealed into the outer shell by the second encapsulant.

    摘要： A system and method for generating white light involves using a combination of phosphor-converted white LEDs and non-phosphor-converted color LEDs to produce white light and adjusting the emitted light in response to feedback signals. Generating white light using a combination of phosphor-converted white LEDs and non-phosphor-converted color LEDs produces white light with an improved CRI and a wide SPD. Adjusting the emitted light in response to feedback allows luminance and chrominance characteristics of the white light to be controlled as the performance of the LEDs changes over time. The emitted light can be adjusted on a per-color basis and/or on a per-group basis, where a group of LEDs includes a combination of at least one phosphor-converted white LED and at least one non-phosphor-converted color LED.

    摘要： An apparatus for illumination comprises a light source operable to generate a radiation pattern. The apparatus further comprises a light guide adjacent the light source, which is operable to be illuminated by the radiation pattern. The light guide comprises a pattern of varying sized dots operable to diffusely reflect the illuminating radiation pattern. The dot pattern comprises monotonically increasing dot sizes intermediate between the smallest and the largest dot sizes, such that the smallest dot size is proximate to the light source and the largest dot size is distal from the light source.
