The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further detailed narration.
The utility model provides a kind of LED lighting device, can be used for being installed in the lift car top board, on sidewall or other the wall panel structure.Be example now, the utility model is carried out comparatively detailed elaboration with a kind of square outward appearance product that is installed in car roof.
Please refer to Fig. 1, Fig. 1 is the structure explosive view of a kind of LED lighting device of the utility model, and as seen from the figure, this LED lighting device comprises circuit board 4, LED lighting means, light fixture fixture 3, even tabula rasa 2 and escutcheon 1.Described LED ray structure is arranged on the described circuit board 4, circuit board 4 is fixed on the end of light fixture fixture 3 by buckle structure, the light of LED ray structure is towards light fixture fixture 3 another opening directions, escutcheon 1 is fixed on the light fixture fixture 3 by buckle structure, its fixing direction is identical with LED ray structure light direction, and the fixed-direction of described escutcheon 1 is the light emission direction of LED ray structure.
Described circuit board 4 is square pcb board, on printed circuit is arranged.The LED ray structure is arranged on the circuit board 4, it is to be made of some LED particles 5, those LED particles 5 are welded on the circuit board 4, be low-power LED, can be on circuit board 4 with the array distribution of 10～20mm spacing, can have parallel connection and/or series relationship between each LED particle 5, connecting more than 5 as three LEDs particles is one group, is not distributed in side by side on the circuit board 4 between the LED particle 5 on the same group.But above-mentioned series relationship in parallel only is used for for example, not as restriction.Be brushed with underwater paint on the circuit board 4 in addition, to prevent the internal circuit damage of making moist.Circuit board 4 back sides also are provided with a radiator 6, and its length and width is all approaching with circuit board 4, highly is about 10～30mm, and this radiator is fixed on the circuit board 4 by screw, are used for strengthening heat radiation.Radiator 6 is for adopting the aluminium alloy heat radiator of extrusion forming process, and anodized is done on the surface.
Escutcheon 1 is as the main peripheral components of light fixture, has appearance and modeling through industrial design, outer surface is to statuesque curved surface, card adopts ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene copolymer) adds PC (Polycarbonate, Merlon) material is made, and its middle part is provided with light inlet window 11, is used for beam projecting.
Escutcheon 1 is a shell structure, and inwall is provided with the 3rd buckle structure 12, in order to and light fixture fixture 3 between buckle be connected and fixed.The utility model is an example with a kind of square structure, in its four inwall central authorities one groove is set respectively.
Below be example with a kind of implementation, described second buckle structure 32 is the buckle structure of projection, and the 3rd buckle structure of escutcheon 1 is a groove, groove and projection are harmonious, and finish fixedly connected; In like manner, circuit board 4 is realized fixing by 33 engagings of first buckle structure.In addition also can be opposite, second buckle structure 32 is set to groove, and the 3rd buckle structure 12 of escutcheon 1 is set to projection, can realize equally.Do not given unnecessary details.
Because of light fixture fixture 3, itself needs certain intensity, and present embodiment can be selected ABS+PC alloy material or PC material or the moulding of PBT (Polybutylece Terephthalate, polybutylene terephthalate) material integrated through injection molding for use.And for improving the light fixture light extraction efficiency, its inwall is provided with reflector layer, or brush reflectorised paint or plating or subsides reflective sheeting etc.
Even tabula rasa 2 is as a kind of auxiliary light transmission assembly, adopt the pmma material of high transmission rate, high fog value, thickness can be at 1.5～3mm, its overall size is greater than the size of the light inlet window 11 of escutcheon 1, thereby can seal light inlet window 11, and through size Control, its size while is less than the size of light fixture fixture 3 lower ending openings, when therefore assembling, it is fixed on light fixture fixture 3 inside, and covers the light inlet window 11 of escutcheon 1.
Below, in conjunction with Fig. 2, be example with a kind of LED lighting device that is used for elevator car roof, assembly structure of the present utility model is described.Among Fig. 2, have installing hole 101 on the lift car top board 100, the size of installing hole 101 is greater than the outer wall profile of light fixture fixture 3, but less than the outline of the flange arrangement 31 of escutcheon 1 inner surface contour and light fixture fixture 3.The circuit board 4 of radiator 6 is housed, is fixedly connected on light fixture fixture 3 tops, and its upper shed is sealed by buckle structure; Installing hole 101 is passed in light fixture fixture 3 bottoms, because of installing hole 101 sizes less than flange arrangement 31, so light fixture fixture 3 is suspended from car top; Even tabula rasa 2 is installed in escutcheon 1 inside, because of its size greater than light inlet window 11, can say that then light inlet window 11 covers fully, the protruding buckle structure 32 of lower end, light fixture fixture 3 outside fastens to finish with the groove 12 of escutcheon internal side wall and fixedlys connected.The light direction of LED particle 5 is towards the direction of even tabula rasa 2, and most of light can evenly mildly shine in the car by behind the even tabula rasa 2.
As shown in Figure 3, be the schematic diagram of a plurality of lamp installation on the lift car top board, only need the car top board that a plurality of installing holes are set and get final product.
Present embodiment only is a kind of situation of the present utility model, but does not limit the utility model, and for example escutcheon is unaware of and can selects plastics for use, or other metalized lamp materials.LED lighting device described in the utility model also can become multiple moulding by industrial design, for example, and circle, hexagon or other appearance and modelings.And, except the car that can be used for elevator, also can be contained in wall, ceiling or the like does not add here and gives unnecessary details.
In sum, LED lighting device according to the utility model preferred embodiment, its circuit board, between light fixture fixture, even tabula rasa and the escutcheon, all do not adopt other supplementary structures, only the buckle structure that is injection molded into by itself industrial design is firmly combined, structure is very simple, and package trade is handy and safe more.Realized that lamp assembly does not adopt the combination of screw or spring etc., be convenient to assembling and maintenance, reduced production cost simultaneously.
Especially, the LED lighting device is combined by protruding buckle structure and escutcheon, need not any extra erecting tools, can reduce cost, and has also improved the security of installation and maintenance.
In addition, the utility model also is provided with heat spreader structures on circuit board, to the heat radiation of circuit board, can play better effect like this, helps to prolong its service life, reduces cost.
More than disclosed only be several preferred embodiment of the present utility model; but the utility model does not limit to once more; any those skilled in the art is under mental condition of the present utility model, can think of variation, all should drop in the protection domain of the present utility model.
