Abstract: front page image
(EN)Low energy consuming sign system composed of discrete light sources, used singly or in groups to create patterns which are observed to constitute single letters, numerals symbols, pictures or complete signs. A group of discrete light sources comprises for example a series-string connection of LED's shunted by a Zener diode. Light energy is only produced when needed, the signs having a high readability in daylight without electrical power. The sign system comprises also a blinking control system and an adapted power supply system with battery back-up facility.
(FR)L'invention concerne une enseigne lumineuse comprenant une chaîne de diodes électroluminescentes montées en série, et une diode Zener shuntant un groupe de diodes électroluminescentes de la chaîne de diodes électroluminescentes montées en série.
