Abstract

An illuminated signage apparatus operable in high ambient light environments and in low ambient light environments comprises a first light source (30) operable in high ambient light environments and a second light source (26) operable in low ambient light environments. The illuminated signage apparatus includes means to detect a relevant ambient light environment threshold and means to switch between the operation of the first (30) and second light sources (26).

Description

technical field [0001] The present invention relates to an illuminated sign apparatus operable in high and low ambient light environments and, by way of example, to a sign light module, such as a traffic signal light module. Background technique [0002] Currently, light-emitting diode traffic signal light modules are used to replace incandescent light traffic light modules. Energy efficiency is the argument for substitution. A standard incandescent traffic signal module consumes about 80W to 120W of electrical energy when lighting, while an LED traffic signal module only consumes 20W to 30W of electrical energy. In addition, LED traffic light modules have a longer service life and require less routine maintenance. [0003] Prior art on LED traffic light modules is disclosed in various publications, including: E ​​Source's Technology Update, November 1995, pp. 1-16 and E Source Publication, 1994, Sections 13.1-13.2.2 . The light-emitting diode traffic signal light module...
