Method and apparatus for a low profile light fixture

Abstract

A method and apparatus for a horticultural light for use in a horticultural facility is provided to minimize a dimension (e.g., height dimension) of the horticultural light. A sheet lens is adhered directly onto the printed circuit board and optionally the underlying metallic backing plate so as to environmentally seal the horticultural light. The sheet lens is comprised of polycarbonate and is pneumatically and/or thermally manipulated to include dome portions that are disposed in proximity to the respective one or more LEDs. Light generated by the LED is incident onto the inner surface of the respective dome portion at right angles through the entire beam angle. Accordingly, substantially none of the light is reflected back into the dome, but is rather propagated to an exterior of the light.
