Abstract

The lighting energy economy method has a sensor measuring ambient light level which provides a measurement value that is input to an electronic module controlling the power supplied to the light sources. The brightness of the sources is lowered in proportion to the darkening of the surroundings. An Independent claim is included for the use of the economizing device in controlling illuminated advertising signs, road signs and illuminated signs in general.

Description

La présente invention concerne un dispositif permettant d'économiserThe present invention relates to a device for saving

l'énergie consommée par les appareillages lumineux selon leur environnement de lumière. Une source lumineuse peut grâce à cette invention baisser d'intensité proportionnellement à l'obscurcissement de son environnement, comme par exemple à la tombée de la nuit. L'effet est  the energy consumed by light fittings according to their light environment. Thanks to this invention, a light source can decrease in intensity in proportion to the darkening of its environment, such as at nightfall. The effect is

réversible à la levée du jour.reversible at daybreak.

Traditionnellement les dispositifs d'éclairage utilisent des systèmes à consommation d'énergie constante, ou quand elle est variable, son principe est inverse à notre invention, c'est à dire visant à augmenter la puissance lumineuse lorsque le jour décline. Le dispositif selon l'invention permet grâce à une sonde mesurant la luminosité ambiante et d'une carte électronique convertissant ces informations en protocole de commande des sources lumineuses de faire  Traditionally, lighting devices use systems with constant energy consumption, or when it is variable, its principle is opposite to our invention, that is to say aimed at increasing the light power when the day wanes. The device according to the invention makes it possible, thanks to a probe measuring the ambient brightness and an electronic card converting this information into a protocol for controlling the light sources, to make

varier la puissance lumineuse et donc d'économiser 20 l'énergie.  vary the light output and therefore save energy.

L'éclairage obtenu est alors optimisé et permettra une réduction de la pollution lumineuse  The lighting obtained is then optimized and will allow a reduction in light pollution

dans les villes et les campagnes.in cities and countryside.
