Title
(EN) METHOD AND APPARATUS FOR COOLING A LIGHTBULB
(FR) PROCÉDÉ ET APPAREIL DE REFROIDISSEMENT D'UNE AMPOULE D'ÉCLAIRAGE
Abstract
(EN)
A device has a plurality of light emitting diodes (LEDs), heat conducting structure that includes a heat pipe and that carries heat from the region of the LEDs to a further location spaced therefrom, and heat dissipating structure that accepts heat from the heat conducting structure at the further location and that discharges the heat externally of the device. In a different embodiment, a device has a radiation generator, a thermal spreader that receives heat emitted by the radiation generator, heat conducting structure that carries heat from the thermal spreader to a location spaced therefrom, and heat dissipating structure that accepts heat at the location from the heat conducting structure and that discharges the heat externally of the device.
(FR)
Le dispositif selon l'invention comporte une pluralité de diodes électroluminescentes (DEL), une structure conductrice de chaleur qui comprend un caloduc et qui transporte la chaleur de la zone des DEL vers une position éloignée séparée de cette zone, et une structure dissipatrice de chaleur qui accepte la chaleur de la structure conductrice de chaleur à la position éloignée et décharge la chaleur à l'extérieur du dispositif. Dans un mode de réalisation différent, le dispositif comporte un générateur de rayonnement, un distributeur thermique qui reçoit la chaleur émise par le générateur de rayonnement, une structure conductrice de chaleur qui transporte la chaleur du distributeur thermique vers une position éloignée séparée de lui, et une structure dissipatrice de chaleur qui accepte la chaleur de la structure conductrice de chaleur à la position éloignée et décharge la chaleur à l'extérieur du dispositif.
