Title (EN) A LIGHT EMITTING DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT
Abstract:
(EN) A light emitting device (1) comprising a luminescent element (2) comprising a first surface (21), at least one cooling element (3) arranged at the first surface of the luminescent element, and a plurality of spacer elements (5) arranged between the cooling element (3) and the first surface (21) of the luminescent element such that the cooling element is arranged spaced apart from the first surface of the luminescent element with a distance, d. The at least one cooling element (3) comprises a compliance such as to be adapted for following warpage of the luminescent element (2) induced by any one or more of clamping forces, forces inflicted by production processes and light and/or heat propagating within the luminescent element, and a force (F) is applied to force the at least one cooling element (3) and the luminescent element (2) together in such a way that no part of the at least one cooling element and the luminescent element are in direct mutual contact.
(FR) L'invention concerne un dispositif électroluminescent (1) comprenant un élément luminescent (2) comprenant une première surface (21), au moins un élément de refroidissement (3) agencé au niveau de la première surface de l'élément luminescent, et une pluralité d'éléments d'entretoises (5) agencés entre l'élément de refroidissement (3) et la première surface (21) de l'élément luminescent de sorte que l'élément de refroidissement est agencé en étant séparé de la première surface de l'élément luminescent par une distance (d). L'élément ou les éléments de refroidissement (3) comprennent une conformité de manière à pouvoir suivre le gauchissement de l'élément luminescent (2) induit par une quelconque ou plusieurs des forces parmi des forces de serrage, des forces infligées par des processus de production et la propagation de lumière et/ou de chaleur dans l'élément luminescent, et une force (F) est appliquée pour forcer l'élément ou les éléments de refroidissement (3) et l'élément luminescent (2) ensemble de telle manière qu'aucune partie de l'élément ou des éléments de refroidissement et de l'élément luminescent n'est en contact direct mutuel.
