摘要： A lighting device for a vehicle, having a plurality of light sources, which are arranged in an array, in particular in line-by-line and column-by-column fashion, and can be operated independently of each other at least in part, wherein the light sources emit light during operation; an exit face through which the light emanating from the light sources passes; and a plurality of extensive boundary elements, which extend at least partly in a region between the light sources and the exit face and serve to separate the light emanating from different light sources, wherein at least some, preferably all, of the extensive boundary elements have a reflector which at least partly reflects the light emanating from one of the light sources in the direction of the exit face.

摘要： A multi-color LED illumination device and specifically a lens comprising a cylindrical opening extending into the lens from a light entry region at which one or more LEDs are configured. A concave spherical surface extends across the entirety of the light exit region of the lens, and a TIR outer surface shaped as a CPC extends between the light entry region and the light exit region. There are various diffusion surfaces placed on the sidewall surface of the cylindrical opening, as well as its upper planar surface and, depending on whether glare control is not needed, the exit surface of the lens. Lunes can also be configured on the sidewall surfaces of the cylindrical opening and if lessening glare is needed, also on the TIR outer reflective surface. The combination of lunes, diffusion elements, and the overall configuration of the lens provides improved color mixing and output brightness according to one embodiment. According to another embodiment, diffusion elements are manufactured and possibly increased on only select surfaces but not on the light exit region in order to lessen glare. Three light interactions in a first portion of light and two interactions in a second portion of light can improve color mixing and beam control. Those interactions includes two refractions either with an intermediate reflection or not, all of which are necessary to achieve the improved performance of the multi-color LED illumination device and lens hereof.

摘要： A luminaire (500) comprising a linearly polarized light source (200) and a collimating reflector (301) arranged to collimate light from the light source towards an optical axis OA. The reflective inner surface of the reflector comprises at least one set of grooves (306), or four spaced zones of grooves, which each extend in a respective plane including the optical axis. Each groove comprises two flat side surfaces to cause light from the light source to undergo a double reflection in the groove, to avoid rotation of each beamlet and thus to reduce loss of imaging of the source. This partly preserves the linear polarization of the source, for use in reducing glare in displays or from lights on the road, or enhancing sparkle for illuminating jewellery.

摘要： A lighting device for professional illumination. The device includes a main housing having a front opening, a first light source, a first reflector configured to receive at least a portion of light emitted by the first light source and to reflect at least a portion thereof, and a second reflector configured to receive at least a portion of light reflected by the first reflector and to reflect at least a portion thereof. The lighting device is configured to emit at least a portion of light reflected by the second reflector out of the lighting device through the front opening. The lighting device further includes an actuator configured to move the first reflector or the second reflector in relation to each other in response to a predetermined control signal.

摘要： Systems and methods for achieving increased irradiation and/or illumination in a photo reactive system is disclosed. In one example, a photo reactive system includes a light source, a refractive cylindrical optic, and a curved reflector. By utilizing the refractive cylindrical optic, angular spread of the light source is reduced, which in turn reduces a size of the curved reflector for directing the light rays onto a work piece. Consequently, a more compact photo reactive system with higher irradiation and/or illumination capabilities can be achieved.

摘要： An optical structure for controlling distribution of light generated by a light source is described. The optical structure includes a primary optics disposed relative to the light source and configured to reflect light generated by the light source towards a target region. The optical structure also includes a secondary optics disposed and aligned relative to the primary optics. The secondary optics is configured to at least partially block light generated by the light source from illuminating a region outside the target region.
