Submersible spotlight

Abstract

A spotlight includes a body (1) with a transparent front (2) and has LED's (5) as light-emitting elements. This spotlight body (1) and the transparent front (2) are made of plastic material and the printed circuit (6) including the LED's (5) is arranged in a juxtaposed arrangement on a metal plate (4) being fit to dissipate the heat being produced by the LED's, the metal plate being cooled by the water flowing into the body (1) of the spotlight through lateral openings (8) being provided in the body. The body (1) is concavely shaped and has the dissipator plate (4) securely attached to it at its open front end, the body (1) having at its center an inner pillar having a hollowed-out portion (10) and an outer open end (11) to receive the spotlight's electric connections (13 and 14) that will be fitted to it. The dissipator plate (4) is securely attached to the peripheral open front end of the body (1) and onto its central pillar (9) with the intermediary of respective O-ring seals (15 and 16).

Claims

1. A submersible spotlight comprising a body with a transparent front and having LED's as light-emitting elements, wherein the body and the transparent front are made of plastic material and a printed circuit comprising the LED's is arranged in a juxtaposed arrangement on a metal plate configured to dissipate the heat being produced by said LED's, said metal plate being cooled by the water flowing into the body of the spotlight through lateral openings in said body.

2. A submersible spotlight as per claim 1, wherein the body is concavely shaped and has the dissipator plate attached to it at its open front end, said body having at its center an inner pillar having a hollowed-out portion and an outer open end adapted to receive the spotlight's electric connections that will be fitted to it.

3. A submersible spotlight as per the claim 1, wherein the dissipator plate is attached to the peripheral open front end of the body and onto its central pillar with the intermediary of respective O-ring seals.

4. A submersible spotlight as per claim 2, wherein the dissipater plate is attached to the peripheral open front end of the body and onto its central pillar with intermediate respective O-rings seals.
