Abstract

La présente invention porte sur un dispositif d'éclairage (1) comprenant : un boîtier (71) présentant une forme sensiblement sphérique ou polygonale ; une pluralité d'unités de source de lumière (10) disposées sur le côté de surface externe du boîtier (71) et comportant chacune un élément électroluminescent (11) permettant d'émettre de la lumière vers l'extérieur depuis ledit dispositif d'éclairage (1) ; et une unité de commande (20) servant à commander la pluralité d'unités de source de lumière (10). Le boîtier (71) comprend : un espace interne (71a) dans lequel est située l'unité de commande (20) ; des premiers orifices d'inhalation (91a) qui sont destinés à permettre à un gaz à l'extérieur du dispositif d'éclairage (1) de s'écouler dans l'espace interne (71a) ; et des premiers orifices d'exhalation (91b) qui sont destinés à permettre au gaz de s'écouler hors de l'espace interne (71a). La pluralité d'unités de source de lumière (10) comprend : une première unité de source de lumière (10X) dans laquelle est intérieurement formé un second orifice d'inhalation (92a) situé à une position correspondant à un premier orifice d'inhalation (91a) ; et une seconde unité de source de lumière (10Y) dans laquelle est intérieurement formé un second orifice d'exhalation (92b) situé à une position correspondant à un premier orifice d'exhalation (91b).
