Abstract
The invention provides a light fixture for illuminating a sign. The light fixture has a lamp and one or more reflectors to provide for substantially uniform illumination of a sign with a minimum number of light fixtures. One or more of the reflectors of some embodiments can formed from a material having predetermined pattern for reflecting and transmitting light from the lamp. For example, the reflectors can be made from a neutral density polymeric material consisting of a translucent or substantially transparent polymeric substrate with a pattern of reflective media disposed on or within the substrate. In some embodiments, one of the reflectors can be a specular reflector. Some embodiments of the light fixture can also include a thermal shield to at least partially prevent thermal convection along a portion of the lamp.
