Abstract: front page image
(EN)A backlight device is provided with: LEDs (28); rectangular plate-like shaped LED boards (30) which each have LEDs (28) arranged on one surface thereof and which are arranged side by side in the direction of extension of the long sides thereof; a heat radiation member (36) which is in contact with the other surfaces of the LED boards (30); and affixation screws (40) which affix the LED boards (30) and the heat radiation member (36) together. Each of the LED boards (30) has a cutout (30c) provided in a short side thereof which is adjacent to another LED board (30). The affixation screws (40) are affixed to the heat radiation member (36) such that the screw shafts (40b) extend from the mounting surfaces of the LED boards (30) through the cutouts (30c) and such that each of the screw heads (40a) is in contact with the mounting surfaces (30a) of adjacent LED boards (30).
(FR)Selon l'invention, un dispositif de rétroéclairage est équipé : de DEL (28) ; d'une pluralité de substrats de DEL (30) prenant une forme de plaques rectangulaire, sur une face desquels les DEL (28) sont agencées et placées en rang dans une direction longitudinale ; d'un élément de dissipation de chaleur (36) en contact avec l'autre face des substrats de DEL (30) ; et d'une vis de fixation (40) fixant les substrats de DEL (30) et l'élément de dissipation de chaleur (36). Une encoche (30c) est agencée sur les substrats de DEL (30), au niveau de celui de leurs côtés courts qui est adjacents à un autre substrat de DEL (30). La vis de fixation (40) est fixée à l'élément de dissipation de chaleur (36) par passage d'une partie axe de vis (40b) depuis des faces montage des substrats de DEL (30) au travers de l'encoche (30c), et vient en contact de chacune desdites faces montage (30a) des substrats de DEL (30) desquelles une partie tête de vis (40a) est voisine.
(JA)バックライト装置は、LED28と、長方形の板状をなし、一方の板面にLED28が配されるとともに、その長辺方向に沿って並んで配された複数のLED基板30と、LED基板30の他方の板面と当接する放熱部材36と、LED基板30と放熱部材36とを固定する固定ビス40と、を備える。LED基板30には、短辺のうち他のLED基板30と隣接する短辺に切り欠き30cが設けられている。固定ビス40は、ビス軸部40bがLED基板30の実装面から切り欠き30cを通して放熱部材36に固定される一方、ビス頭部40aが隣り合うLED基板30の各々の上記実装面30aと当接する。
