Title (EN) LIGHTING ASSEMBLIES AND SYSTEMS
(FR) ENSEMBLES D'ÉCLAIRAGE ET SYSTÈMES
Abstract:
(EN) The present disclosure relates to illumination or lighting assemblies and systems that provide illumination using LEDs. In one aspect, the present disclosure provides a lighting assembly, comprising: multiple light emitting diodes that emit light; an optical system that directs the light emitted by the light emitting diodes, the optical system positioned adjacent to light emitting diodes; and a cooling fin including a two-phase cooling system, the cooling fin positioned adjacent to the light emitting diodes such that the two-phase cooling system removes heat from the light emitting diodes. In another aspect, the present disclosure provides a lighting system including multiple lighting assemblies. The lighting assemblies and systems of the present disclosure can be used in, for example, a street light, a backlight (including, for example, a sun-coupled backlight), a wall wash light, a billboard light, a parking ramp light, a high bay light, a parking lot light, a signage lit sign (also referred to as an electric sign), static signage (including, for example, sun-coupled static signage), illuminated signage, and other lighting applications.
(FR) La présente invention porte sur des ensembles d'éclairage et des systèmes fournissant un éclairage à l'aide de diodes électroluminescentes. Sous un certain aspect, la présente invention porte sur un ensemble d'éclairage comprenant : des diodes électroluminescentes multiples émettant de la lumière ; un système optique dirigeant la lumière émise par les diodes électroluminescentes ; le système optique étant positionné adjacent aux diodes électroluminescentes ; et une ailette de refroidissement comprenant un système de refroidissement à deux phases, l'ailette de refroidissement étant positionnée adjacente aux diodes électroluminescentes de telle sorte que le système de refroidissement à deux phases retire la chaleur des diodes électroluminescentes. Sous un autre aspect, la présente invention porte sur un système d'éclairage comprenant des ensembles d'éclairage multiples. On peut utiliser par exemple les ensembles et systèmes d'éclairage de la présente invention dans un éclairage de rue, un rétro-éclairage (comprenant, par exemple, un rétro-éclairage couplé au soleil), un éclairage mural, un éclairage de panneau publicitaire, un éclairage de rampe de parking, un éclairage en hauteur, un éclairage d'aire de stationnement, un signal lumineux de signalisation (également appelé signal électrique), une signalisation statique (comprenant, par exemple, une signalisation statique couplée au soleil), une signalisation éclairée et d'autres applications d'éclairage.
