Housing for a LED Lighting System
First Claim
1. A light fixture for wash lighting, comprising:
- a housing which includes an elongate first wall and an elongate second wall spaced apart from and generally parallel to the first wall, wherein the housing includes a reflector portion having at least a first segment defined by an elliptical function and a second segment defined by a parabolic function; and
a light source positioned within the housing generally at a focus of the parabolic function.

Abstract
The LED light fixture includes white LEDs having multiple, different color temperatures. Preferably, white LEDs having color temperatures of about 3500 and about 5000 degrees Kelvin (K) are selected. The intensity of each LED may be varied and the light radiated from the LEDs is mixed together. The resulting light emitted from the housing is a white light having a variable color temperature ranging from about 3500 to about 5000 K. The housing is preferably extruded aluminum. A portion of the housing is configured to mix the light together and to focus the light such that the output light is about thirty degrees off center. Electrical loading is off set to minimize load on power supplies.

11. A light fixture providing a focused output light comprising:
-
a housing having a first side wall with a first lower section and a first upper section, a second side wall with a second lower section and a second upper section, and a lower surface connecting the first side wall and the second side wall at a lower edge of each of the first and second lower sections, respectively; a circuit board engaging a first support connected to the first lower section and a second support connected to the second lower section, the first and second supports spaced from the lower surface a substantially equal amount; and a plurality of light emitting diodes (LEDs) mounted to an upper surface of the circuit board and oriented to emit light between the first upper section and the second upper section, wherein; the first upper section and the second upper section are generally curved surfaces, and each LED is positioned substantially at a focus of the curve. - View Dependent Claims (12, 13, 14, 15)
