Abstract

1376396 Operating lamp ORIGINAL HANAU QUARZLAMPEN GmbH 28 July 1972 [9 Aug 1971] 35446/72 Heading F4R An operating lamp has a bulb 12 with a metallized dome 14 which reflects light on to reflector 16. The reflector 16 may be conventional or transmit IR but reflect visible radiation. The beam from 16 passes through IR filter 18 to IR reflector 32 which transmits visible radiation but reflects IR. The visible radiation passes through cathedral glass 30 i.e. a diffuser.
