Description

DESCRIPTION
"Wall mounted LED lighting"
[0001] The present invention relates to wall mounted LED lighting.
[0002] It is known how in the interior lighting sector, both in domestic and work premises, LEDs are becoming increasingly widespread, given their many advantages'.
[0003] However, the use of LEDs has some drawbacks, among which, in particular, the uneven illumination of the environment achieved, caused by the concentrated emission of light, typical of LEDs.
[0004] The aim of the present ' invention is to mak,e. wall- mounted LED lighting which overcomes such drawbacks.
[0005] Such purpose is achieved by LED lighting . made according to claim 1.
[0006] The characteristics and advantages of the LED lighting according to the present invention will be evident from the description given below, made by way of a non-limiting example, in accordance with the appended drawings wherein:
[0007] - figure 1 shows LED lighting according to one embodiment of the present invention;
[0008] - figure 2 shows the LED lighting in figure 1, from a idifferent view point;
[0009] - figure 3 shows a transversal section view of the LED lighting in figure 1; and
[0010] - figure 4 shows a schematic view of a small plate with LED emitters.
[0011] According to the present invention, the lighting 1 comprises a main body 2 extending mainly along a longitudinal axis X which, the lighting being mounted on a wall, is generally horizontal.
[0012] The body- 2 is generally composed of a section,., for example in aluminium or its alloys;.
[0013] The body 2 comprises a- front- wall 4, having its main extension along the longitudinal axis X, and an end wall 6 which extends transversally from a rear rim 8 and a front rim 10; the front wall 4 is connected to the end wall 6- at a predefined distance from the rear rim.
[0014] Preferably, the section 6a of the end wall 6, positioned rearwards of the front wall 4, is less extensive transversally ' than the section 6b of the end wall 6, positioned ' in forwards' of said front wall 4.
[0015] Moreover, preferably, the end wall -6. is inclined, in relation to the front wall 4, preferably so as to form. an acute angle on the front.
[0016] With the lighting 1 mounted on the wall, the end wall 6 proves preferably inclined upwards.
[0017] The lighting 1 further comprises a plurality of LED emitters 30, supported by the front wall 4, abreast of each other and aligned along the longitudinal axis X.
[0018] Preferably, ' the lighting 1 comprises a plurality of small plates 32, each comprising a predefined number of LED emitters 30; the small plates 32 are positioned abreast of each other, and. aligned along the longitudinal axis X.
[0019] Preferably, the lighting 1 has a layer of heat conducting adhesive 40, positioned between the surface of the plate 32 facing the front wall 4 and the surface, of said front, wall 4 , so as' to facilitate heat dispersion between- the plate 32 and the main body 2 of the lighting.
[0020] Preferably, the adhesive is made from a loaded polymer, for example an acrylic polymer loaded with ceramic material, while the support tape is made from. silicone treated polyester; preferably, the tape is double .
[0021] The- lighting .1 further comprises a reflector 50, positioned Opposite the LED' emitters 30, extending■ along the longitudinal axis X, supported by the section. 6b of the end wall 6.
[0022] In transversal cross section, the reflective surface of the reflector 50 is inclined . downwards from the front wall towards the -front rim 10 of the end wall 6.
[0023] Preferably, , the main body 2. comprises a prominence 52/ projecting from the end wall 6 towards the front wall 4, which the rim of the reflector 50 rests on, the other rim being laid directly on the' end wall.
[0024] Preferably, the transversal cross section of the reflector 50. has a concave section 50a, for example arched and · without any corners, which extends from the front wall towards the front rim 10 of the end wall 6, and a convex section 50b, connected to the concave section 50a to rest the reflector firmly against the end wall 6.
[0025) In particular; the reflector 50 has a reflective surface treated · so as to produce a fine roughness, suitable to reflect the rays. of light coming from the LED emitters in a diffuse, even manner.
[0026] In other . words, the surface treatment of the reflector gives the aluminium practically no iridescence - and makes it highly multidirectional.
[0027] For example, .the reflector is surface processed to as to. give the aluminium
[0028] a-multidirectional finish;
[0029] - a longitudinal 60° gloss of 70 to 90, preferably 80, measured · according to ISO 7668;.
[0030]- a .transversal 60° gloss of 65 to 85, preferably. 75, measured according to ISO 7668;
[0031]- a total reflectance of 80 to 100, preferably. 91, measured according to DIN .5036/3; [0032]- a diffuse reflectance of 60 to 80, preferably 70, measured according to DIN 5036/3;
[0033]- a substantially nonexistent iridescence.
[0034] The lighting 1 is suitable for being mounted to the wall of a premises -
[0035] In particular, the main body 2 is fitted with connection means for attachment to the wall.
[0036] For example, according to one, embodiment, the lighting 1 comprises an attachment section 60, extending along the longitudinal axis -X, with a VC" section, attachable to the wall/ for example by threaded coupling.
[0037] The main body 2, and in particular the front wall 4, can be hooked: to the section 60, SQ that the rear section 6a of the end wall 6 places sits, below said section 60, to hide it from view.
[0038] Preferably, moreover, the lighting comprises a cover in transparent material, for example in Plexiglass, which covers the front section of the end wall and the · LED emitter's,
[0039] According to one embodiment, moreover, a plurality of lights I concur to form an assembly wherein the lights are aligned longitudinally and electrically connected to each .other.
[004.0], Innovatively, the- present invention forms an asymmetric LED wall lighting, with indirect light, able. to spread the light produced by the LEDs evenly.
[0041] Advantageously, the reflector makes it possible to reflect the light ' coming from the emitters without preferential directions, diffusing it towards the ceiling or into the room without concentration.
[0042] According to a further advantageous aspect/ the reflector is a separate component from the main body, so as to permit it to be shaped according to optical requirements .
[0043] According to yet a further advantageous aspect, the heat is efficiently dispersed throughout the main body, preventing harmful overheating from occurring.
[0044] Advantageously, moreover, groups of LED emitters are grouped on the plates, to easily connect the same to the support on the side of the front wall.
[0045] According to yet a further advantageous aspect, the concave shape of' the reflector is designed so that, once the angle of emission of the LED emitters and their position in relation to said reflector has been defined there is no return reflection illuminating the back wall which the lighting is attached to. "
[0046] It is clear that a person skilled in the art may make variations to the lighting described above so as to satisfy contingent requirements while remaining within the sphere of protection as defined by the following claims .
