Abstract: One or more LED dice (10) are mounted on a support structure (12). The support structure (12) may be a submount with the LED dice (10) already electrically connected to leads on the submount. A mold (14) has indentations (16) in it corresponding to the positions of the LED dice (10) on the support structure (12). The indentations (16) are filled with a liquid optically transparent material, such as silicone, which when cured forms a lens material. The shape of the indentations (16) will be the shape of the lens (22). The mold (14) and the LED dice/support structure (10,12) are brought together so that each LED die (10) resides within the liquid silicone in an associated indentation (16). The mold (14) is then heated to cure (harden) the silicone. The mold (14) and the support structure (12) are then separated, leaving a complete silicone lens (22) over each LED die (10). This over molding process may be repeated with different molds to create concentric shells of lenses. Each concentric lens may have a different property, such as containing a phosphor, providing a special radiation pattern, having a different hardness value, or curable by a different technique (e.g., UV vs. heat).

Abstract: The present invention relates to a luminaire comprising an array of LEDs emitting light of at least one color, and a control system for controlling the light output of the luminaire. The control system comprises photosensor array for detecting light output of the luminaire. An imaging unit is arranged in front of the photosensor array such that it maps an image of said array of LEDs on said photosensor array. The photosensor array is divided into subareas each detecting light output from a single one of the LEDs. The control system uses the output of the subareas for controlling the luminaire light output. Thus, it is possible to act on different LED light colors or the light output of individual LEDs without having to separate them in time by means of a time pulsing method.

Abstract: In this invention, the first refraction groove and the second refraction groove, which are located on two opposite ends of the reflection lens, are set on the same central axis. The said lens features a translucent shell and is of a horn- shaped appearance. The horn or cone-shaped mouth points from the first refraction groove to the second refraction groove. The outer surface is designed to have multiple reflection sections. When the LED light source is positioned at or in the first refraction groove, the light emitted from LED is refracted by the first refraction groove and then is sent out from the cone mouth at the second refraction groove. Meanwhile, the light which gets through the translucent lens shell is refracted by the multi-section reflection surface and then is also projected from the cone mouth. The reflection surface lens in this invention integrates multiple functions within the one body including focusing, refraction and reflection, which allows uniform illumination and other desired illumination effects without the need for any reflective coating. It simplifies the processing technique of LED illumination systems and reduces processing costs.
