CA 2302227

Disclosed herein is a current control for a lighting assembly, which may be an LED lighting assembly, which may be a pulse width modulated ("PWM") current control or other form of current control where each current-controlled unit is uniquely addressable and capable of receiving illumination color information on a computer lighting network. In an embodiment, the invention includes a binary tree network configuration of lighting units (nodes). In another embodiment, the present invention comprises a heat dissipating housing, made out of a heat-conductive material, for housing the lighting assembly. The heat dissipating housing contains two stacked circuit boards holding respectively the power module and the light module. The light module is adapted to be conveniently interchanged with other light modules.

L'invention concerne une commande de courant pour ensemble d'éclairage (éventuellement à diodes électroluminescentes), qui peut être une commande de courant à modulation d'impulsions en largeur ou une autre forme de commande de courant dans laquelle chaque unité commandée en courant est adressable de manière unique et capable de recevoir l'information de couleur d'éclairage sur un réseau d'éclairage informatique. Selon une variante, les unités (noeuds) d'éclairage obéissent à une configuration de réseau à arborescence binaire. Selon une autre variante, l'ensemble d'éclairage est logé dans une enceinte de dissipation thermique en matériau à conductivité thermique. Cette enceinte renferme deux cartes imprimées superposées accueillant respectivement le module d'alimentation et le module d'éclairage. Le module d'éclairage est facilement interchangeable avec d'autres modules d'éclairage.
