Patent ID: 8864326

Claim:
A diving light for underwater photography, comprising: a housing or body containing a battery and electronics, the body having a sealed interior compartment and having an intermediate plate at a front of the sealed interior compartment of the body and a multi-contact electrical connector exposed at a front side of the intermediate plate, a face assembly connected to and removable from the front of the body, the face assembly including a face plate securable against the front of the body and a bezel ring removably secured by screw threads to the body and retaining the face plate against the body, the face plate being of heat-conducting metal and facing forward, and the bezel being removable so as to remove the face plate from the body, the face plate being configured to be reversed in orientation after removal, and re-secured to the body with the bezel, providing an inoperative configuration, the face plate including an LED array positioned to project through a window in the face plate, with a metal core circuit board at rear of the face plate, the LED array being mounted on a front side of the metal core circuit board, and the rear side of the metal core circuit board having electrical contacts, the face plate, the metal core circuit board and the intermediate plate of the body being configured such that the metal core circuit board makes tight thermal-transferring contact with the intermediate plate when the face plate is retained on the body with said bezel ring, and such that the electrical contacts of the metal core circuit board make connection with the multi-contact electrical connector of the body, the face plate being positioned to be in direct contact with water including at the front side of the face plate such that heat from the LED array is conducted from the metal core circuit board into the metal face plate and directly into the water, the LED array being sealed within the face plate against water intrusion independently of connection to the body, and an external water-sealed switch on the body for switching the LED light on and off and for selecting power levels.
