An apparatus, method, and system to provide, as one example, up-light for aerial viewing from downwardly aimed wide area, high intensity, lighting fixtures. The method controls a small percentage of light from the fixture to pass up and away for up-light, with the remainder used to produce a controlled, concentrated beam to a target. Some embodiments include a substantial amount of glare and spill light control. An apparatus can include a lamp and fixture with a visor length that is shorter than most conventional spill and glare control visors. The visor allows a controlled, relatively small percentage of direct light from the fixture for a desired or needed level of aerial illumination, but efficiently directs other light to the target. Optionally, a reflective plate is positioned inside the visor to reflect a small percentage of light from the fixture upwardly for up-light. Another embodiment can shift a fraction of light in direction(s) different than the main light output of the fixture.
An apparatus for producing a generally controlled, concentrated beam from an elevated position towards a target area as well as glare and spill light control and uplighting comprising:
An apparatus for providing up-lighting from a sports lighting fixture which is adapted to generate a generally controlled, concentrated beam along a central aiming axis to an aiming point on a sports field, the fixture including a reflector with upper and lower portions and a high intensity discharge light source, the apparatus comprising:
A lighting fixture for lighting a target area from an elevated position, the lighting fixture comprising:
