    摘要: The present invention relates to a LED module (10) comprising a substrate (12), at least one LED chip (20) mounted on a first side of said substrate, and an optical element (21) covering the LED chip(s) (20). The substrate (12) is further provided with at least one via channel (22) extending from the first side of the substrate to a second opposite side of the substrate, whereby the via channel(s) is provided with conducting means for electrically connecting the at least one LED chip (20) to a control circuit (32). By providing the substrate with via channels with conducting means, the control circuit may be connected at the second side (the bottom side) or at the edge of the substrate. Thus, no top mounted electrical interface is required from the substrate, which is advantageous with respect to miniaturization, light emission, etcetera.

    摘要: 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 (3a) 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.
