ABSTRACT:
A lighting panel used to control locally unidirectional light is constructed from a plurality of light modifying elements that substantially control the distribution of light within a control range. Each element is disposed in the panel to receive the unidirectional light and has a surface means for critically reflecting the received light and for refracting the initially reflected light upon leaving the elements into the control range.
