ABSTRACT:
A cryophotonic back-lit sign for use at night or during low-light conditions. The sign includes an AC ballast for providing a source of AC power. A cryophotonic lamp is disposed in a potting material, that is preferably made from mixing together a two-part epoxy. The lamp is connected to receive the AC power from the AC ballast. A retroreflective sheeting is provided on a transparent substrate, which is removably attached to a top surface of the potting material. The sheeting allows light to substantially pass from a rear surface thereof to a front surface thereof. Light is provided to illuminate the sign either from light from vehicle headlights that reflect off the sheeting and back towards the vehicle, or from the cryophotonic lamp when not enough light is available to illuminate the sheeting.
