Abstract
(EN)
The present invention facilitates transfer of heat from a light source to a heat radiation part, such as a heat sink, formed as a portion of a case by adopting an assembly allowing preferable workability. Disclosed is a display formation device being provided with: a housing including a heat radiation part; a substrate having a light source mounted thereon; a lens member through which light emitted from the light source transmits; and a holding member that is fixed to the housing by means of a fastening member and that holds the lens member. The substrate is provided such that a force is transmitted to/from the holding member along a first direction. The housing has a first attachment part. The first attachment part has a surface inclined in such a manner as to be oriented to the advancing side in the fastening direction of the fastening member, toward the heat radiation part along the first direction, when viewed in a second direction intersecting the first direction and the fastening direction. The holding member has a second attachment part which has a surface parallel with the surface of first attachment part, and the holding member is fastened to the first attachment part by means of the fastening member which passes through a hole or a cutout formed in the second attachment part.

La présente invention facilite le transfert de chaleur d'une source de lumière à une partie de rayonnement de chaleur, telle qu'un dissipateur de chaleur, formé en tant que partie d'un boîtier en utilisant un ensemble permettant une aptitude au façonnage préférable. L'invention concerne un dispositif de formation d'affichage comprenant : un logement comprenant une partie de rayonnement de chaleur ; un substrat sur lequel est montée une source de lumière ; un élément lentille à travers lequel la lumière émise par la source de lumière est transmise ; et un élément de maintien qui est fixé au logement au moyen d'un élément de fixation et qui maintient l'élément lentille. Le substrat est conçu de telle sorte qu'une force soit transmise à/depuis l'élément de maintien le long d'une première direction. Le logement comprend une première partie de fixation. La première partie de fixation a une surface inclinée de manière à être orientée vers le côté d'avance dans la direction de fixation de l'élément de fixation, vers la partie de rayonnement de chaleur le long de la première direction, lorsqu'elle est vue dans une seconde direction croisant la première direction et la direction de fixation. L'élément de maintien a une seconde partie de fixation qui a une surface parallèle à la surface de la première partie de fixation, et l'élément de maintien est fixé à la première partie de fixation au moyen de l'élément de fixation qui passe à travers un trou ou une découpe formé(e) dans la seconde partie de fixation.
