LED-Lampe mit einer optischen Scheibe und mit einem wärmeabführenden Gehäuse

摘要

A lamp (10) has a cup-shaped body (12) with a bottom (14) with a sidewall (16) defining a top (18). The body (12) is thermally conductive. A reflective coating (20) is provided on the inside surface bottom (14) and side wall (16) for reflecting light from a side emitting LED (22) that is mounted on a thermally conductive, electrically insulating coupling (24) and is centered on the bottom (14). A lens (26) for directing light emitted from the LED (22) in a desired direction is provided and preferably is a Fresnel optic. The lens (26) can close the opening (18) or it can be formed as an integral part of bottom (14) or it can be added to the bottom (14). Alternatively, the lens (26) can be solid with the lens elements either external or internal. Electrical connections (28, 30) to the LED extend through the cup-shaped body (14).
