Abstract:
A lighting system is disclosed comprising a light source unit(1) and a projection system(2) for producing a desired light distribution pattern in a target area, especially for use in an automotive head lighting, studio and theatre lighting, indoor spots with adjustable beam width or direction, architectural dynamic lighting, disco lighting and other. The lighting system is especially suitable for a light source unit (1) having one or a plurality of Lambertian light sources(11), especially a plurality of LEDs. For generating a desired light distribution pattern in the target area, the light source unit(1) comprises a plurality of collimators (12) which are dimensioned and/or arranged especially such that the curved focal plane (P) of the projection system(2) intersects with or tangentially touches the exit apertures of the collimators (12).

One or more light source devices (4) are integrated into the lamination layer as well as at least one photovoltaic cell (13). Substantially transparent conductors (3) provide connections between the light source device or devices and the cell or cells, and a rechargeable battery arrangement (15) is charged by the at least one photovoltaic cell and for providing power to the light source device or devices.
Abstract:
A light emitting device, comprising a flexible substrate (2) with a single, structured conductive layer (5), and a plurality of LEDs (3) arranged on said substrate (2), said structured conductive layer (5) forming electrodes for driving said LEDs (3). The structured conductive layer comprises a plurality of heat dissipating pads (8), each having an area significantly larger than the area of each LED (3), and each LED (3 a) is thermally connected to at least one of said pads (8a), and electrically connected in series between two pads (8a, 8b). Through this design, each LED is thermally connected to a relatively large heat dissipating area, and the thermal energy built up in the LED will be distributed over this area, and then dissipated upwards and downwards from this area. As the addressing can be handled by a single conducting layer, the flexibility of the substrate is improved compared to multilayer substrates. By connecting each LED in series between two pads, a very large portion of the conducting layer can be used for the pads, and very little area needs to be occupied by conducting tracks, which otherwise may be a problem with single layer designs.
