Abstract:
An LED assembly that includes optics and optical arrangements for light emitting diodes (LEDs). In some embodiments, a reflector is provided within a void between the lens and the LED. This reflector can reflect light emitted by the LED in a non-preferred direction back toward the preferred direction. In other embodiments, an optical element is formed or otherwise provided in the lens cavity and shaped so that, when the lens is positioned above the LED, the refractor bends the emitted light in a preferred direction. In some embodiments, both a reflector and optical element are provided in the LED assembly to control the directionality of the emitted light. Such embodiments of the invention can be used to increase the efficiency of an LED by ensuring that generated light is being directed to the target area of choice.
