SOLID STATE LIGHTING UNIT INCORPORATING OPTICAL SPREADING ELEMENTS

摘要

A desired output from a solid state lighting assembly is generated using a combination fo a light assembly and an external protective lens. Provided are aspects in which the spreading and/or steering of aimed beams from individual light elements is achieved by through sections formed into an external protective lens. This may be embodied either in a luminaire originally designed to utilize solid state lighting elements, such as LEDs, or in a retrofit device or mechanism designed to convert an existing luminaire that uses a traditional light source into a luminaire that uses solid state lighting elements.
