Description of drawings

Fig. 1 is the schematic perspective view according to the described reflector module case as one of the utility model embodiment.

Fig. 2 is the oblique stereogram of Fig. 1.

The specific embodiment

With reference to the accompanying drawings the utility model is done further explanation.

The utility model provides a kind of lamp tube type lamp box; Comprise Lamp case frame and light-source system, said light-source system comprises a plurality of compact arranged side by side reflector modules, and said reflector module comprises a box body; As shown in Figure 1; Said box body 20 comprises a transparent front plate 21 and a reflecting plate 22, and said front shroud 21 is oppositely arranged the spatial accommodation that formation one is used to hold lamp tube light source with reflecting plate 22, has the relative light shielding part 23 of a plurality of and said light source position on the said front shroud 21.

These light source module case as one closely are arranged in the Lamp case frame side by side, just can form complete lamphouse light source system.Existing lamp box generally also need be provided with a monoblock softbox after showing picture except Lamp case frame and light-source system, the strong and weak different light that light source is sent obtains shining on the picture after even softening is handled again.And the utility model is owing to used the light source box structure; Its transparent front plate just can use the softbox material; Play the effect of the even softening of light that light source is sent; Being equivalent to the light that the whole light source system sends just has been the light after handling through even softening, therefore no longer the monoblock softbox need be set, and has saved cost.

Said light shielding part can be to be formed at the light shield layer structure on the said front shroud by opaque or translucent material.

Light source in the light source box shown in Figure 1 is a fluorescent tube, and said light shielding part 23 is a plurality of shading strip shapes parallel with fluorescent tube.

Reflecting plate shape among Fig. 1 is from lamp strip position 24 to be launched to both sides waveform or broken line stairstepping symmetry, in addition, also can be to be other shapes such as concave arc line style.

Specifically, said light shielding part can comprise two shading strips parallel with fluorescent tube, and the gap between said two shading strips is over against fluorescent tube, and the diameter in said gap is less than the diameter of fluorescent tube.Like this, both can see through the high light of a part, but this part high light is unlikely to again to see through too much, can comes through the width in gap the high light that sees through is adjusted through the gap.

In addition, said light shielding part can comprise a plurality of shading strips parallel with fluorescent tube, the six roots of sensation for example shown in Figure 1, and said a plurality of shading strips can distribute to bilateral symmetry from lamp strip position.

As shown in Figure 2, shading strip 23 can be a continuous shading line, also can be made up of a plurality of interrupted chopping points, and the slit between the chopping point can see through the light of light source, is unlikely to the light of highlights is all blocked, in order to avoid cause black line.

Said chopping point can be circle or polygon or network structure; Also can be circle (annular) or the polygonized structure that is hollow.

The hollow bulb of said chopping point is over against lamp tube light source; Can high light be seen through; But then can play the effect that the high light luminous flux that sees through is controlled through control hollow bulb area; For example, the area that can control said hollow bulb is less than 50% of the area of light shielding part, to reach the balance between distance and the brightness evenly.

Know that through concrete test if reach the even brightness effect equally, when supposing no light shielding part, front shroud is d1 with the distance of showing picture; When using solid chopping point, front shroud is d2 with the distance of showing picture; When using annular chopping point, front shroud is d3 with the distance of showing picture; The relation that d3＜d2＜d1 is then arranged.This is that hypotelorism can make light source on picture, form bright spot easily because when not using light shielding part; And solid chopping point forms dim spot at light source position easily when hypotelorism; And annular chopping point can average out on this nearer distance.

Said box body is an airtight box body, can further comprise up and down side plate and left and right sides edge sealing, with said front shroud and reflecting plate is airtight surrounds; Or further comprising side plate, left and right sides edge sealing and a base plate up and down, said base plate is positioned at the reflecting plate below, with side plate and left and right sides edge sealing engage the airtight box body of formation up and down.

The described transparent front plate of the utility model can be complete transparent or semitransparent front shroud, gets final product so long as can see through the material of light, for example complete transparent or semitransparent materials such as glass, PC plate, light-passing board, softbox, ground glass.

If adopt the bright front shroud of full impregnated, then can be so that the light disposable transmission as much as possible that light source is sent is 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 (like softbox, milk blank etc.); The light that then can light source be sent through translucent protecgulum with part light reflected back reflector; Secondary reflection is gone out again; So, then be equivalent to carry out earlier shining again to the picture exhibition direction after the uniform treatment, make that the light that sees through translucent front shroud is softer on the whole through the light that translucent protecgulum sends light source.

For instance; The background color of the displaying picture on being arranged on lamp box is that white or light color are when being; Tunica albuginea or light film and the part of the light that light source sends through this displaying picture be reflected back toward the reflecting plate side, form the secondary reflection irradiation again to picture, come and go repeatedly reflection through this; Utilize the diffraction of light effect, can the light that light source sends be carried out even softening and handle; But the background color of the displaying picture on being arranged on lamp box is black or dark color 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 reflected back reflecting plate side, this has just reduced the chance of secondary reflection, also reduced the even light effect of reaching via secondary reflection; This will produce bright wisp on the displaying picture; Influenced the bandwagon effect of lamp box, can only prolong light path and weaken bright wisp through increasing the thickness of lamp box; But this can increase manufacturing cost undoubtedly, and influences attractive in appearance.

For this situation; If front shroud is set to translucent protecgulum, the light that will light source be sent through the secondary reflection that this translucent protecgulum forms at first promptly carries out even softening in cassette interior to be handled, and has been equivalent to form a light box that sends uniform light; When light that light box sends arrives the black film of showing picture or dark film has been the light after even light is handled; Avoided on the displaying picture, producing bright wisp, so just can reduce the thickness of lamp box greatly, because light path shortens; Also increase overall brightness, or under the constant situation of brightness, can reduce power consumption.

The box body structure that the utility model forms through 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, the long-term back of using is adsorbed with dust outside transparent front, also be easy to the dust that smooth transparent front is external and clean out.

And the utility model can formed jointly the integral inverted love dart plate of lamp box by the combination of a plurality of reflector modules; Therefore; The installation or the debugging of whole lamp box reflecting system are accomplished in the operation that only needs a people just can pack into or split out single reflector module very easily.This is for the subway lamp box, and advantage is more obvious.From the consideration of security, before not allowing, the lamp box that is used for subway do not uncap, and can only be the lamp box reflector to be carried out installation and maintenance through the mode of uncapping in the bottom.Under 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 having to the entire emission plate drawn off.And utilize the utility model, can the module taking-up at the light source place that should damage be got final product.
