Abstract: An LED cooling system includes a plate, the plate includes a plurality of slots for positioning a plurality of LEDs and at least one gap for substantially isolating each of the plurality of LED slots from one another such that heat from each of the plurality of LEDs has at least one non-interfering path towards an edge of the plate, thereby heating of one LED is substantially uninfluenced by heating of other LEDs in the plurality of LEDs.

Abstract: The present invention provides a compact, portable light sour-ce (1), preferably sized to be readily hand-held, for illuminating an object, several objects, or areas for human use and/or machine operation. The function of the portable light source (1) is controlled by a first microprocessor (51) located inside the portable light source. The first microprocessor (51) is externally accessible either through a direct link to an external control unit (54) or through a link involving one or more other microprocessors located in accessible positions of the portable light source. The function can hence be customized by the user himself to any given situation making the portable light source especially suitable for professional use, i.e. for security, police and military use.

Abstract: The present invention provides a compact portable light source capable of providing powerful light as well as effect light and is especially suitable for professional use, i.e. for security, police and military use. The invention relates to a portable torch having a plurality of light emitting diodes and a heat sink, namely a portable torch (1) comprising a case (2) having a first and a second open ends, a first cap (3) covering the first open end and a second cap (4) covering the second open end, said first cap having a transparent area (6), illumination means having a diode area (11) comprising a plurality of light emitting devices (LEDs) arranged to emit light out of the first open end and through the transparent area (6) of the first cap (3), a heat sink (14) arranged to transport heat from the light emitting devices, a power source comprising a battery holder and means (7) for activating said power source operatively associated with said case (2).
