Abstract
A light distribution assembly includes an electrodeless HID light source providing emitted light along substantially first and second hemispherical zones. A first optical element redirects a portion of light from the first hemispherical zone into a first desired direction in the second hemispherical zone. A second optical element redirects at least a portion of light within the second hemispherical zone. Other optical elements may be added to tailor the light distribution. Various combinations of these components may be used to create the desired illumination pattern.
