Abstract: Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

Abstract: A retainer ring for a light fixture includes a cylindrical main body section that defines a cylindrical axis, and an inner retaining flange that extends radially inward from a distal end of the main body section.

A customization kit for a light engine that defines an optical axis includes a retainer ring configured to couple with the light engine, and two or more primary optics that are mechanically compatible with the light engine, and retainable to the light engine with the retainer ring. When the retainer ring couples with the light engine, a cylindrical axis of the retainer ring coincides with the optical axis.

Abstract: To improve efficiency, particularly for general illumination applications, a source of green or yellow light includes a solid state device (e.g. a laser diode) to produce an infrared laser beam and a light frequency up-converter to convert the infrared light into green or yellow light. A luminaire includes such a source as well as a source providing two other colors of light, such as red and blue (e.g. not green or yellow). The emitters of the other source may be light emitting diodes or additional laser diodes. The luminaire outputs a combination of the various colors of lights from the sources, for example, to produce white light. If the different emitters are independently controllable, the luminaire may be adjusted or ‘tuned’ to output white light of different color characteristics and/or to output combined light of various colors over a wide region of the visible light color gamut.

Abstract: A light fixture controller is configured for controlling the color temperature and intensity of a light fixture that includes at least two LED groups. Each LED group includes multiple LEDs configured to produce light at certain color temperatures. The light fixture controller receives a color temperature setting and an intensity setting for the light fixture and generates control signals based on these settings. A first control signal only turns on the first LED group for a first duration of a cycle and a second control signal only turns on the second LED group for a second duration of the cycle. The ratio between the first and second duration is determined based on the color temperature setting. The control signal further includes a dimming control signal for controlling a current flowing through the LED groups based on the intensity setting for the light fixture.

Abstract: A cleansing lighting device includes a laser light source configured to emit light in the visible light spectrum or in the infrared light spectrum. The cleansing lighting device also includes a light frequency up-converter to convert longer wavelength light from the laser light source to shorter wavelength light. The converted light has a dominant wavelength in the portion of the ultraviolet range at or below 380 nm, suitable for the cleansing application. An example cleansing lighting device may also include an optical element, such as a beam shaping lens or a variable optical beam deflector, to distribute the resulting ultraviolet light from the up-converter for the cleansing application. Such a cleansing lighting device may be a standalone device, although the device or individual components for light-based cleansing may be incorporated in a luminaire, for example, together with an artificial light source adapted to general illumination.
