Torch
First Claim
1. A portable torch comprisinga case having a first and a second open ends, a first cap covering the first open end and a second cap covering the second open end, said first cap having a transparent area,illumination means having a diode area comprising a plurality of light emitting devices (LEDs), one being a central diode, arranged to emit light out of the first open end and through the transparent area of the first cap,a heat sink system arranged to transport heat from the light emitting devices, wherein said heat sink system comprises a rod as a central part of a first material, wherein said material is copper, gold or silver or a metal or a metal alloy having a heat capacity and/or a heat conductivity as copper, gold or silver, wherein said central part is extending axially from the central diode, and two peripheral parts of a second material, said first material is different from said second material, and wherein said two peripheral parts are spaced apart from each other and connected through the central part, and wherein each of said peripheral parts is arranged with a plurality of radially extending parts,a power source comprising a battery holder,means for activating said power source operatively associated with said case.
