Abstract
The disclosure of the present invention includes light fixtures having variable LED array sizes to form different beam angles. These light fixtures are particularly suitable for sports/venue lights and are characterized by highly concentrated high power small LED light sources including small light sources of different size LED arrays which may include additional diffusion. The present disclosure also includes a lens which substantially dissipates light to reduce if not eliminate glare. The lens may be pressed, chemically etched (pickled), or sandblasted to become a micro-lens. The lens may, alternately, be a plastic material. A further aspect of the present disclosure is the incorporation of a segmented reflector to greatly reduce glare. A single reflector may be segmented in its circumference or may be formed of multiple individual segments.
