Problems solved by technology

[0014] Even though the lighting devices disclosed by WO11076213 and WO11076219 are extremely efficient, said lighting devices still have some disadvantages, since the manufacturing of the lighting devices is relatively expensive due to the need for individually configured LEDs and TIR lenses

Embodiment Construction

[0030] Figure 1A A cross-sectional view through the center of the lighting device 100 is shown (indicated by the dotted line A-A in Fig. Ib). The lighting device includes a lighting unit 110 with a plurality of light sources 111 , a light collector 120 with a plurality of lenslets 121 , a grid 130 and an optical projection system 140 .

[0031] Light source 111 may be in the form of a light emitting diode (LED), discharge lamp, OLED, PLED, plasma light source, incandescent light source, fluorescent light source, phosphor-based light source, or other suitable light source. A single light source 111 may include one or more light source units, eg, two or more light source units having different colors. For example, the light source may comprise one luminaire for emitting eg white light, may comprise three light emitting diodes with red, green and blue chips (referred to as RGB 3in1 LEDs) or may comprise a LED with red, green, blue and white Four light-emitting diodes on a chip...

Abstract

The present invention relates to a lighting device, which includes a plurality of light sources and a light shutter that emit light; a light collector arranged between the light source and the light shutter; and an optical projection system adapted to project light along the optical axis. The shutter is imaged at a certain distance. The concentrator is adapted to collect light from a plurality of light sources, and wherein the concentrator includes a plurality of lenslets that collect light from the light sources and convert the light into a plurality of light beams that propagate along an optical axis. beam. The lenslets are arranged in a dense pattern, with a plurality of outermost adjacent lenslets positioned along outer circumferential boundaries and at the same radial distance from the center of the concentrator. The dense pattern is obtained by optimizing the packing density defined by the ratio of the sum of the areas of the circular cross-sections of the lenslets to the area of ​​the outer circular boundary.

Description

technical field [0001] The present invention relates to optical lenses, and in particular to optical lenses and lens arrays for collecting light from an array of light sources. Background technique [0002] Luminaires that create various effects are increasingly used in the entertainment industry in order to create various lighting effects and mood lighting in connection with concerts, live shows, TV shows, sporting events or as part of architectural installations. Typically entertainment luminaires create beams with beam width and divergence, and for example may be bath luminaires that create relatively wide beams with uniform light distribution, or they may be contour lighting luminaires suitable for projecting an image onto a target surface. [0003] Light emitting diodes (LEDs) are increasingly being used in lighting applications due to their relatively high efficiency, low power consumption, long lifetime, and / or the ability to be electronically dimmed. LEDs are used i...
