Detailed description of the invention
The present invention is described further with reference to the accompanying drawings.
As shown in Figure 1, embodiments of the invention provide a kind of module group type light source box device for lamp box, comprise a box body 10, described box body 10 comprises transparent front plate 11 and a reflecting plate, described front shroud 11 is oppositely arranged formation one for holding the spatial accommodation of light source with reflecting plate, described front shroud 11 has at least one light shielding part relative with described light source position 12.
These light source box are arranged closely in Lamp case frame side by side, just can form complete lamphouse light source system.Existing lamp box is except Lamp case frame and light-source system, and generally also need to arrange a monoblock softbox after displaying picture, the light that the power that light source is sent is different is irradiated on picture after obtaining even soften handled again.And the present invention is owing to employing light source box structure, its transparent front plate just can use softbox material, play the effect of the even softening of the light sent by light source, be equivalent to light that whole light-source system sends just be through even soften handled after light, therefore no longer need to arrange monoblock softbox, save cost.
Described transparent front plate 11 can be formed by all-transparent or translucent material, and described light shielding part 12 can be the light shield layer structure be formed at by opaque or translucent material on described front shroud, such as, be attached on front shroud by modes such as serigraphys.
As shown in Figure 2, for LED case, the position of light shielding part 12 faces LED light source, avoids the excessively strong irradiation of the direct light of LED forward to displaying picture, thus makes overall light more even.
In existing lamp box, if show that picture distance light source is excessively near, then can cross by force due to the light in the region nearest apart from light source and cause the dark space in other regions, the light forming overall picture is irregular, even can see the bright spot of light source in picture, therefore, have to show that the distance of picture and light source zooms out, but the integral thickness so just causing lamp box strengthens, and not only makes manufacturing cost increase, and wasting space.
According to embodiments of the invention, by light shielding part, this part high light is sheltered from, or filter out a part, make it basically identical with the light intensity in other regions, therefore avoid the bright secretly irregular problem of picture when displaying picture distance light source is nearer.And the area of light shielding part can according to the shape of the distance of light intensity, picture and light source and light source and specific design.
Shown in Fig. 3, for the module group type light source box schematic perspective view according to another embodiment of the present invention, comprise a box body 20, described box body 20 comprises transparent front plate 21 and a reflecting plate 22, described front shroud 21 is oppositely arranged formation one for holding the spatial accommodation of light source with reflecting plate 22, described front shroud 21 has the relative light shielding part 23 of multiple and described light source position.
Light source in light source box shown in Fig. 3 is fluorescent tube, and described light shielding part 23 is in multiple shading strip shape parallel with fluorescent tube.
Reflecting plate shape in Fig. 3 is launched to both sides waveform or broken line stairstepping symmetry in from lamp strip position 24, in addition, also can be other shapes such as concave arc line style.
Shading strip 23 can be continuous print shading line; Or be made up of multiple interrupted chopping point, and the gap between chopping point can, through the light of light source, be unlikely to the light of highlights all to block, in order to avoid cause black line.
Specifically, described light shielding part can comprise two shading strips parallel with fluorescent tube, and the gap between described two shading strips is just to fluorescent tube, and the diameter in described gap is less than the diameter of fluorescent tube.Like this, both can by gap through the most high light of a part, but this part high light is unlikely to again through too much, by gap width to through high light adjust.
In addition, described light shielding part can comprise multiple shading strip parallel with fluorescent tube, such as, the six roots of sensation shown in Fig. 3, and described multiple shading strip can distribute from lamp strip position to bilateral symmetry.
For LED case, described light source then can comprise multiple LED, and described light shielding part is the chopping point relative with the position of described LED.
Chopping point of the present invention can be circular or polygon or network structure; Also can be the circle (annular) in hollow or polygonized structure.
The hollow bulb of described chopping point is just to light source, then can play as described above to through the effect that controls of high light luminous flux, such as, the area that can control described hollow bulb is less than 50% of the area of light shielding part, to reach the balance between distance and brightness uniformity.
Know by specifically testing, if reach the effect of brightness uniformity equally, when supposing without light shielding part, front shroud is d1 with the distance of displaying picture; When using solid light shielding part, front shroud is d2 with the distance of displaying picture; When using annular light shielding part, front shroud is d3 with the distance of displaying picture; Then there is the relation of d3 < d2 < d1.This is because when not using light shielding part, hypotelorism can make light source easily on picture, form bright spot; And solid light shielding part easily forms dim spot when hypotelorism at light source position; And annular light shielding part can obtain the balance of brightness in this nearer distance.
As shown in Figure 4, be the decomposing schematic representation of the reflector module (light source box body) according to another embodiment of the present invention, comprise reflecting plate 101, epipleural 102, lower side panel 103, left edge sealing 104, right edge sealing 105, and transparent front plate 106; Described front shroud 106 is oppositely arranged with reflecting plate 101, and encloses the airtight spatial accommodation of formation one by described upper and lower side plate 102,104 and left and right edge sealing 104,105, for airtight accommodation light source, described reflecting plate 101 has multiple light source mounting hole.Light source can be various, such as bulb, fluorescent tube or LED illuminator etc.
Wherein, the shape of described reflecting plate can be various, such as, can be to form at least one groove, and as shown in Figure 5, reflecting plate 101 has two grooves, and described light source mounting hole 1011 then can be positioned at the bottom of described groove.Light source can be arranged at by this installing hole 1011 on the reflecting plate in spatial accommodation by installation personnel, and the circuit accessories such as required electric wire or circuit board can be installed in after reflecting plate through installing hole.Described reflecting plate can utilize the flanging 1012 formed in the middle part of base to be connected by screw with upper and lower side plate.Certainly, reflecting plate might not to be enclosed with upper and lower side plate by the design of this flanging and be connected, in fact, if left and right edge sealing and reflecting plate are integrated, and the connection of left and right edge sealing and upper and lower side plate just can play the effect enclosing and connect reflecting plate, the connection of flanging 1012 then serves the effect strengthening bonding strength further.
The Main Function of left and right edge sealing is used to fixing front shroud, plays sealing function in side simultaneously.The shape of edge sealing can be tabular or angle steel shape (forming in-flanges shape) etc., being all fine, particularly in order to fasten front shroud, generally all can forming an in-flanges to withhold front shroud.But no matter which kind of shape, because edge sealing has certain thickness and width, when it is positioned in light path, can cause certain blocking to source light, form low light level district; And be positioned at the edge of die set due to edge sealing, when combine in lamp box connect side by side use time, low light level district can not get light filling and scope becomes large, therefore just easily forms dark space or underworld in edge sealing position.
According to one embodiment of present invention, the part of left and right edge sealing higher than reflecting plate left and right side can be formed by transparent material, certainly, also left and right edge sealing all can be made up of transparent material, obviously also belong to protection scope of the present invention.The loss caused light due to transparent material is less, therefore, can avoid the formation of dark space.And left and right edge sealing can be fixed with front shroud higher than the part of reflecting plate left and right side in one-body molded or split, the present invention does not limit this.
And according to another embodiment of the present invention, by the in-flanges on edge on the edge sealing of left and right and the joint of front shroud, can front shroud be fixed.Front shroud can be fixed on above or below in-flanges by bonding mode; Also by the mode of pressing, front shroud can be buckled in the below of in-flanges, front shroud is fixed.And there is multiple hollow-out parts on described in-flanges, by the design of hollow-out parts, more light can be allowed to pass through, decrease blocking light.
The shape of hollow-out parts can be various, such as oval, square etc., or in sawtooth waveforms or the form such as the breach of square-wave-shaped, as long as stop light that can be as far as possible few can also fix front shroud simultaneously.
And after described in-flanges hollow out, easy deliquescing in quality, may be not enough to the support force of front shroud, at this moment, according to embodiments of the invention, a stile can also be formed further in in-flanges outer, as shown in Figure 6, stile 10511 makes the intensity of whole in-flanges 1051 obtain enhancing, thus also makes the intensity of right edge sealing 105 be enhanced.
It can also be seen that in figure 6, can be enclosed by Plug Division 1052 grafting between right edge sealing 105 and upper and lower side plate.Connected structure is not only firm, and serves the effect of position correction each other.
In addition, device of the present invention can further include at least one light source mounting bar 106, as shown in Figures 4 and 5, described mounting bar is arranged at reflecting plate rear and is connected with described upper and lower side plate, and mounting bar having multiple light resource installing section 1061, position is corresponding with the light source mounting hole 1011 on described reflecting plate.And in order to strengthen the intensity of mounting bar, a support member 107 can also be increased, be positioned at the below of mounting bar 106, and engage fixing with edge sealing, support mounting bar from middle part, in order to avoid mounting bar subsides, also the intensity of whole reflecting plate is served to the effect of enhancing simultaneously.
Embodiment as shown in Figure 7, described mounting bar 106 can be grooved, and trough rim 1062 and described reflecting plate fit, and be provided with multiple light source installation sheet 1061 in notch, described light resource installing section is positioned on installation sheet.And notch inner bottom part can also hold the circuit of light sources wire etc. of drawing from installation sheet, cabling in the enclosure space in notch, very safe, convenient.
By mounting bar, after can light source installation being fixed in advance, integral installation is in die set again, convenient just as installation fluorescent tube, improves field-installed efficiency; And mounting bar has lived reflecting plate in supported underneath, strengthen integrally-built stability; On the other hand, carry due to light source mounting bar and secure light source, because this simplify the structural design of the installation position in reflecting plate.
Transparent material of the present invention, referring to can through the material of light, all-transparent or the translucent materials such as such as glass, PC plate, light-passing board, softbox, ground glass.
If adopt all-transparent front shroud, then can so that the light disposable transmission as much as possible sent by light source be gone out, comparing the background color being suitable for picture exhibition is that white or light lamp box show picture; And when adopting translucent front shroud (as softbox, milk blank etc.), some light is reflected back reflector by translucent protecgulum by the light that then light source can be sent, secondary reflection is gone out again, so, irradiate again to picture exhibition direction after the light being then equivalent to be sent by light source by translucent protecgulum first carries out uniform treatment, make the light through translucent front shroud softer on the whole.
For example, when the background color being arranged on the displaying picture on lamp box is for white or light color system, the light that light source sends part by the tunica albuginea of this displaying picture or light film be reflected back toward reflecting plate side, form secondary reflection again to irradiate to picture, by this round multiple reflections, utilize the diffraction effect of light, the light that light source can be sent carries out even soften handled; But, when the background color being arranged on the displaying picture on lamp box is black or dark color is, the black film of this displaying picture or dark film will absorb the light that light source sends, and can not or seldom by light reflection back reflective plate side, this reduces the chance of secondary reflection, also reduce the even light effect reached via secondary reflection, this will produce bright wisp on displaying picture, have impact on the bandwagon effect of lamp box, can only by increasing the thickness of lamp box, extend 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, namely first the light that light source is sent by the secondary reflection that will be formed by this translucent protecgulum carry out even soften handled in cassette interior, be equivalent to define the light box that sends uniform light, light after being dodging when the light that light box sends arrives the black film or dark film of showing picture, avoid and produce bright wisp on displaying picture, so just can reduce the thickness of lamp box greatly, because light path shortens, too increase overall brightness, or can power consumption be reduced when brightness is constant.
The box body structure that the present invention is formed by airtight spatial accommodation, light source is in use isolated from the outside, extraneous dust is directly adsorbed on the surface avoiding light source, even if due to the electrostatic interaction that light source produces, outside transparent front, be adsorbed with dust after Long-Time Service, be also easy to dust external for smooth transparent front to clean out.
And the present invention can be made up of the integral inverted emitter plate of lamp box jointly the combination of multiple reflector module, therefore, the operation only needing a people just can load single reflector module or split out, completes installation or the debugging of overall lamp box reflecting system very easily.This is for subway lamp box, and advantage is more obvious.For the consideration of security, uncapping before not allowing for the lamp box of subway, can only be carry out installation and maintenance by the mode of opened at bottom to lamp box reflector.In a prior art situation, if there is a light source point to be damaged in lamphouse light source, because the uncap operating space of lamp box, the end is narrow and small, keep in repair after maintenance personal needs to have to be drawn off by whole reflecting plate.And utilize the present invention, the module at the light source place of this damage can be taken out.
According to one embodiment of present invention, the groove structure of reflecting plate 101, can be sawtooth waveforms or tool spaced forward triangle wave mode etc., can also be trapezoidal waveform.The groove structure of trapezoidal waveform, not only bottom land is plane, conveniently can install light source, and the adjacent slot body side surface tool of adjacent grooves is at regular intervals, and forms a plane.If adjacent grooves close proximity, then the angle that adjacent slot body side surface is formed easily forms bright line at the relative position of displaying picture, have impact on the bandwagon effect of picture; And the dual-side of adjacent two grooves is spaced a distance, form a plane, then the light that light source can not be made to send due to this plane place is formed to be assembled, and avoids the appearance of bright line.Meanwhile, the plane of formation too increases the self-strength of reflecting plate, when with transparent front conflict support time, can better and transparent front fit, improve the compactness of box body entirety.
The base of trapezoidal wave and the angle of dual-side are preferably greater than or equal to the lighting angle of light source, namely the side of 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, such as when the lighting angle of light source be 40 degree-120 spend time, if the angle of described base and side is less than 120 degree, then can stop the direct projection light of light source, therefore, preferably, the base of trapezoidal wave and the angle of 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 picture exhibition plate can be reflected is reflected back picture exhibition direction again.
Along trapezoidal wave base to top margin direction, the distance in described trapezoidal wave side and picture exhibition direction shortens gradually, and just, the light be reflected back from picture exhibition direction is also from trapezoidal wave base portion to both sides diminuendo, like this, we can see, nearest position, described side distance picture exhibition direction is also the most weak part of the light that is reflected back from picture exhibition direction, and the most weak light is reflected back picture exhibition direction by light path again that so can be the shortest.Thus, along side by that analogy, the light of crescendo can be reflected back picture exhibition direction with gradually long light path, achieve the even of overall light.
The height of described die set preferably matches with the height of described lamp box, certainly according to actual conditions to highly carrying out relative set, such as can highly be less than the height of lamp box, and can be arranged in lamp box, the present invention is not construed as limiting this.
Further, the side of the groove of described reflecting plate can have many fins, and to increase the even light effect to secondary reflection light, these fins can be parallel with described groove notch edge, and on the stepped side being distributed in described groove.The stairstepping of reflecting plate can according to the quantity of the light source point of the size of reflecting plate and setting, extend, the ladder plane wherein had in stairstepping reflecting plate, the light that transparent front aspect is reflected back with as far as possible short light path retroeflection to transparent front, if be not form projection at described end difference, and be still the inclined-plane of trough rim, so, light will with larger light path oblique retroeflection to transparent front, exactly because and define ladder plane, then the angle of retroeflection light can be tried one's best forward in transparent front; Meanwhile, distance light source region far away, its light intensity is more weak, and due to the gradient of cell body, the region that light intensity is more weak, its stair-stepping convex plane can more early receive light and with shorter light path retroeflection light, therefore, serve even light effect further.
Stair-stepping convex plane is only area in order to control sensitive surface or height, and the area of sensitive surface and be highly all can have difference according to situation on the spot, stairstepping is only preferred embodiment.
