Abstract
A solid-state light emitting device strip lighting system. The system includes an elongated fixture, a reflector, and a strip including a plurality of solid-state light emitting devices electrically connected in series disposed along the fixture. A heat sink and/or the reflector is formed as an integral part of the elongated fixture. In one aspect of the invention, a beam angle of the plurality of light emitting devices perpendicular to the long axis of the elongated fixture is adjustable by varying the height of the strip containing the devices. In an additional aspect of the invention, at least one end cap is connected to the strip containing the devices in such a way that an external power converter and/or controller may be connected to the end cap to power and/or control the devices. These strip lights are daisy chainable in series, eliminating the need for multiple drops of AC supply wiring.
