On décrit maintenant plus spécialement le dispositif d'éclairage à LED 3 (figures 13 à 19).The LED lighting device 3 (FIGS. 13 to 19) is now more specifically described.
Le dispositif d'éclairage 3 comporte d'abord un carter support et de protection 24, allongé, de forme générale pseudo trapézoïdale. Le carter 24 comporte une grande plaque supérieure 25, opaque. Le carter 24 comporte également une face inférieure 26 laissant passer la lumière fermée une partie de protection 26a tel qu'un capot transparent associé de façon amovible mais avec une étanchéité suffisante à la plaque supérieure opaque 25. Le carter comporte enfin deux joues 27 d'extrémité longitudinale, dont une est pourvue de moyens
d'interconnexion 28 avec des moyens complémentaires prévus à cet effet vers l'extrémité du bras 9.The lighting device 3 comprises firstly an elongate support and protection housing 24 of generally pseudo trapezoidal shape. The housing 24 has a large upper plate 25, opaque. The casing 24 also has a lower face 26 allowing the closed passage to pass through a protective portion 26a such as a transparent cap associated removably but with sufficient sealing to the opaque top plate 25. The casing finally has two cheeks 27 of longitudinal end, one of which is equipped with interconnection 28 with complementary means provided for this purpose towards the end of the arm 9.
On comprend que la direction générale du carter 24 est l'horizontale dans le cas le plus simple, ou moyennant une inclinaison sur l'horizontale en fonction des nécessités de l'éclairageIt is understood that the general direction of the housing 24 is the horizontal in the simplest case, or by tilting on the horizontal according to the needs of lighting
Le dispositif d'éclairage 3 comporte ensuite des moyens porteurs 29 en forme générale de plaque, mais pouvant être également en forme générale de pseudo plaque, nappe, pseudo nappe ou analogue.The lighting device 3 then comprises carrying means 29 in the general form of plate, but may also be in the general form of pseudo plate, web, pseudo tablecloth or the like.
Ces moyens porteurs 29, sont fixes et fixés au et logés dans le carter 24. Ils s'étendent dans un plan orthogonal à la plaque supérieure opaque 25. Ils sont donc placés dans un plan général vertical.These carrying means 29 are fixed and fixed to and housed in the housing 24. They extend in a plane orthogonal to the upper opaque plate 25. They are therefore placed in a vertical general plane.
Ces moyens porteurs 29, fixes, définissent un référentiel fixe en vue de l'orientation des LED.These fixed carrier means 29 define a fixed reference for the orientation of the LEDs.
