Abstract

A pocket torch has a lower part (23) with an insulated contact point (231) and a high power bulb (21) fixed on the lower part with an anode electrode (211) and cathode electrode (212). A housing (24) is fixed to the lower part (23) and has several cooling fins (241) for removal of heat generated by the high power bulb (21). A reflector (22) is mounted around the high power bulb (21) for reflecting the light radiated from the high power bulb. A power source has a positive terminal (2611) which is connected to the contact point (2311) and a negative terminal which is connected to the lower part (23) for power supply of the high power bulb (21). An independent claim is given for a housing fixed to a lower part.
