Description of drawings
Fig. 1 is according to the described light source module of embodiment of the invention stereogram partial schematic diagram;
Fig. 2 is the schematic cross-section of light source module shown in Figure 1.
The specific embodiment
The present invention is described further with reference to the accompanying drawings.
In general, lamp box comprises Lamp case frame and light-source system, and light-source system of the present invention is made of a plurality of side by side compact arranged led light source die sets, as shown in Figures 1 and 2, according to the described light source module 100 of the embodiment of the invention, can comprise grooved metallic plate 101, described grooved metallic plate 101 has a base plate 1011, be provided with LED substrate 102 on the described base plate, the light that LED1021 is sent shines towards the notch direction.
The material of grooved metallic plate can be aluminium, and is not only lightweight, and good heat dissipation effect.For led light source, the most important thing is heat dissipation problem, the present invention uses metallic plate to connect the LED substrate, has solved heat dissipation problem.Wherein, described LED substrate 102 can be by heat conduction jointing material 104, and for example heat conductive silica gel is connected on the described base plate 1011, makes better heat-radiation effect.
Described light source module 100 can further include transparent front plate 103, is installed on the notch place of described grooved metallic plate 101.The transparent front plate can make the light source and extraneous relative isolation in the described light source module, forms relatively airtight space, reduces the absorption of dust; And, existing lamp box is generally in order to strengthen even light effect, the capital arranges a transparent even tabula rasa between light-source system and displaying picture, and it is suitable with the lamp box front face area to spare the tabula rasa area, be difficult for installing, and cost is very high, the present invention then the present invention then no longer needs this even tabula rasa, but be equivalent to even tabula rasa is divided into the front shroud that a plurality of and described module notch area is complementary, not only weight lightens, and installs easily, and raw-material requirement has also been reduced, can use leftover pieces to finish, reduce cost.
The transparent material of described transparent front plate, referring to can be through the material of light, all-transparent or translucent materials such as glass, PC plate, light-passing board, softbox, ground glass.
If adopt the all-transparent front shroud, then can be so that the light disposable transmission as much as possible that light source is sent to be gone out, the background color that relatively is suitable for picture exhibition is showed picture for white or light lamp box; And when adopting translucent front shroud (such as softbox, milk blank etc.), the light that then light source can be sent is returned the part light reflection by translucent protecgulum, secondary reflection is gone out again, so, then be equivalent to carry out first shining again to the picture exhibition direction after the uniform treatment by the light that translucent protecgulum sends light source, so that it is softer on the whole to see through the light of translucent front shroud.
For instance, the background color of the displaying picture on being arranged on lamp box is that white or light color are when being, the light that light source sends by this displaying picture tunica albuginea or light film and part be reflected back toward the reflecting plate side, form again the secondary reflection irradiation to picture, by this round Multi reflection, utilize the diffraction of light effect, the light that light source can be sent carries out even soften handled; But, the background color of the displaying picture on being arranged on lamp box is that black or dark color are when being, the black film of this displaying picture or dark film will absorb the light that light source sends, and not can or seldom with light reflection back reflective plate side, this has just reduced the chance of secondary reflection, also reduced the even light effect reached via secondary reflection, this will show that picture produces bright wisp, affected the bandwagon effect of lamp box, can only be by increasing the thickness of lamp box, prolong light path and weaken bright wisp, but this can increase manufacturing cost undoubtedly, and affect attractive in appearance.
For this situation, if front shroud is set to translucent protecgulum, will the light that light source sends at first namely be carried out even soften handled in cassette interior by the secondary reflection that this translucent protecgulum forms, be equivalent to form a light box that sends uniform light, light after when light that light box sends arrives the black film of showing picture or dark film, being dodging, avoided showing that picture produces bright wisp, so just can reduce greatly the thickness of lamp box, because light path shortens, also increase overall brightness, or in the constant situation of brightness, can reduce power consumption.
The upper edge of described grooved metallic plate can have respectively installation portion, and described transparent front plate is installed on the notch place of described grooved metallic plate by described installation portion.
Block and for fear of installation portion LED light is caused, described installation portion should preferably be positioned at the outside of extended line of the side plate of described grooved metallic plate.As shown in Figure 2, installation portion can be to be positioned at the mounting groove 1013 and 1014 that the upper edge of described grooved metallic plate is oppositely arranged, by the dual-side of the described transparent front plate 103 of described mounting groove clamping.As can be seen from Figure 2, the position of mounting groove is positioned at the outside of extended line of the biside plate of grooved metallic plate, can not block the light of LED.
If the installation position is inner in grooved metallic plate side plate extended line, then can cause LED light and block, at this moment, the part that installation portion can be sheltered from described transparent front plate forms a plurality of hollow-out parts, to reduce the blocking of LED light, avoid adjoiner formation dark space or concealed wire at module and module.The shape of hollow-out parts can be various, such as oval, square etc., or is the forms such as breach of sawtooth waveforms or square-wave-shaped, so long as can be the as far as possible few light that stops can also be fixed front shroud simultaneously and get final product.
Except the form of mounting groove, can also be other forms of installation portion, for example form a mounting plane, by bonding mode front shroud is bonded on the mounting plane.
In order to make substrate more firm, can also be formed with a left fin 10111 and a right fin 10112 at described base plate, described left fin and the described LED substrate 102 of right fin clamping.
The outside of described grooved metallic plate can also have a plurality of radiating fins 1012, further increases heat dissipation.
For strengthening seal, the present invention can also comprise upper cover plate and lower cover, encloses a confined space with described grooved metallic plate and transparent front plate, and led light source is closed, and avoids the adhesion of dust, and also easily cleaning.
In addition, described grooved metallic plate inboard can have reflective material layer, and for example spraying or coating one deck reflectorised paint or reflective membrane improve optical efficiency more.
The box body structure that the present invention forms by airtight spatial accommodation, light source in use is isolated from the outside, avoided the surface of light source directly to adsorb extraneous dust, even because the electrostatic interaction that light source produces, adsorbing outside transparent front after long-term the use has dust, also is easy to the dust that smooth transparent front is external and cleans out.
And the present invention can be come jointly to form by the combination of a plurality of light source modules the integrated light source system architecture of lamp box, therefore, the lamp box that is no longer necessary for the different in width specification is made the integrated light source system of different in width, and only need to can satisfy by the number of combinations of module the requirement of different in width specification lamp box, make the more standardization of manufacturing of light-source system, and, during installation and maintenance, installation or the debugging of whole lamp box reflecting system are finished in the operation that only needs a people just can pack into or split out single module very easily.This is for the subway lamp box, and advantage is more obvious.For the consideration of security, before not allowing, the lamp box that is used for subway do not uncap, and can only be by the mode of opened at bottom the lamp box reflector to be carried out installation and maintenance.In the prior art situation, if there is a light source point to be damaged in the lamphouse light source, the operating space of lamp box is narrow and small owing to uncap in the end, and the maintenance personal keeps in repair after need to having to whole reflecting plate drawn off.And utilize the present invention, the module taking-up of being somebody's turn to do the light source place of damaging can be got final product.
The cross section of described grooved metallic plate can be toroidal, and the width of opening part is greater than baseplate width, but concrete shape can be various, for example, similar with the described shape of Fig. 1, the other embodiment according to the present invention, the cross section structure of grooved metallic plate can also be trapezoidal waveform.The bottom surface of trapezoidal wave and the angle of biside plate are preferably more than or equal the lighting angle of light source, the side that is trapezoidal wave is in outside effective lighting angle of light source, the lighting angle of light source is the light scattering angle of light source, for example when the lighting angle of light source be that 40 degree-120 are when spending, if the angle of described base and side less than 120 degree, then can stop the direct projection light of light source, therefore, preferably, the angle of the base of trapezoidal wave and dual-side should be not less than 120 degree.Like this, because lamp box is secondary reflection equipment, the trapezoidal wave side of reflecting plate not only can not stop the direct projection light of light source, and the light that the direction from the picture exhibition plate can be reflected is reflected back the picture exhibition direction again.
Along the trapezoidal wave base to the top margin direction, the distance of described trapezoidal wave side and picture exhibition direction shortens gradually, and just, the light that is reflected back from the picture exhibition direction is also from trapezoidal wave base section to the both sides diminuendo, like this, we can see that the described side position nearest apart from the picture exhibition direction also is the most weak part of light that is reflected back from the picture exhibition direction, so can the shortest light path the most weak light be reflected back the picture exhibition direction again.Thus, along side by that analogy, the light of crescendo can be reflected back the picture exhibition direction with gradually long light path, realize the even of overall light.
The height that the height of described die set is preferably with described lamp box is complementary, certainly can be according to actual conditions to highly carrying out relative set, and for example height is less than the height of lamp box, can be installed in the lamp box get final product, novel this is not construed as limiting.
Further, described grooved metallic plate inboard can have many fins, and to increase the even light effect to secondary reflection light, these fins can be parallel with the notch edge of described grooved metallic plate, and on the stepped side that is distributed in described groove.The ladder plane that the stairstepping fin has, the light that the transparent front aspect is reflected back with as far as possible short light path retroeflection to transparent front, if be not to form projection at described end difference, and be still the tapered plane of side plate, so, light will be with the oblique retroeflection of larger light path to transparent front, exactly because and formed the ladder plane, the forward of then angle of retroeflection light can being tried one's best is in transparent front; Simultaneously, apart from light source zone far away, its light intensity is more weak, and since the gradient of cell body, the zone that light intensity is more weak, and its stair-stepping convex plane can more early receive light and with shorter light path retroeflection light, therefore, further play even light effect.
Stair-stepping convex plane only is for the area of controlling sensitive surface or height, and the area of sensitive surface and highly all be to have according to situation on the spot differently, stairstepping only is preferred embodiment.
