Patent ID: 7226178

Claim:
A lamp for an underwater camera to illuminate and photograph or film objects in the macrorange, characterized in that a minimum of three LED diodes ( 1 ) emitting white light are arranged concentrically and at the same distance from each other around, and at a specific angle to, the optical axis ( 14 ) of the underwater camera ( 25 ), either by means of an annular lamp holder ( 12 , 24 ) or by directly integrating these lamps into the housing of the camera; characterized in that each LED lamp ( 1 ) is a light-emitting diode ( 5 ) that produces white light at a maximum illumination angle of 140° and is arranged and sealed watertight in a housing ( 2 , 3 , or 3 , 12 , 16 ), and in that the light-emitting diode ( 5 ) is mounted onto a cooling plate ( 6 ) that is in contact with a housing part ( 2 or 20 , 16 ) made of heat-conducting material.
