And described circular ultrathin lamp box also comprises split pin, and this split pin runs through the through hole radially that is formed at described chock, so that described loam cake and described lower cover strong bonded.

The utlity model has following beneficial effect

1, exquisite appearance, ultra-thin, the thickness of traditional round lamp house is at least 8CM, and the utility model thickness can only be 1.6CM;

2, conventional lightbank mostly adopts straight type fluorescent lamp or ring-like fluorescent lamp to do backlight, and energy consumption is higher, and the utility model adopts the lower LED of energy consumption to do light source, and is under the same brightness effect, more energy-conservation more than 70% than conventional lightbank;

3, line source is become area source, illuminance is more even, soft, vision is more comfortable;

4, make full use of the backlight transmissison characteristic of material, light disengages the rate height, and it is more even, natural that light is propagated;

5, open design fast, it is simpler, faster to change the lamp sheet.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment embodiment of the present utility model is described.

Fig. 1 and Fig. 2 show the front elevation and the side view of the circular ultrathin lamp box of the utility model.The utility model is the voltage-stabilized power supply power supply by 12 volts.As shown in Figure 2, voltage-stabilized power supply interface 11 and lamp box switch 12 are housed in the lamp box side.

Fig. 3 shows the lower cover internal structure of the circular ultrathin lamp box of the utility model, and as shown in Figure 3, the lower cover of lamp box comprises: LED (light emitting diode) lamp bar 1, LGP 3, PVC plug 10, chock hole 2.Wherein, LED lamp bar 1 and LGP 3 are main illuminated components.

Wherein, the manufacture craft of LED lamp bar 1 is that to adopt soft pcb board (printed substrate) be substrate, is illuminator with the LED of high brightness, and per two LED spacings are 1 centimetre, is arranged in equably on the pcb board, and formation strip light source can arbitrarily curve and is arc.Spacing between the LED is set to 1 centimetre can guarantee the even of light source, can not cause local shade.

LED lamp bar 1 is attached to around the circular LGP 3 external diameter edges as light source.Reflectance coating 7 (see figure 5)s on the lining of LGP 3 back sides utilize LGP to meet the principle of anaclasis, and line source is become area source, thus uniformly light-emitting.Outer rim on PVC backboard 9 (see figure 6)s is stained with a circle PVC plug 10, and is thicker than LGP 3 and LED lamp bar 1, plays lateral support and shading.

Fig. 4 is the loam cake figure of the circular ultrathin lamp box that provides according to embodiment of the present utility model.This loam cake is made up of the acrylic material, mainly plays the effect of printing opacity and protection internal structure.With reference to Fig. 5 its concrete structure is described below.

Fig. 5 is the loam cake side sectional view of the circular ultrathin lamp box that provides according to embodiment of the present utility model.

With reference to Fig. 5, the critical piece of loam cake comprises acrylic shadow shield 4 from top to bottom successively, acrylic panel 5 and chock 6.Wherein, the material of acrylic shadow shield 4 is lighttight black acrylics, and main effect is to cover light source in the front, prevents that picture is local luminous bright excessively.Acrylic panel 5 is acrylics of transparent material, mainly plays the effect of printing opacity and guard lamp sheet 7 (that is picture).Chock 6 in the loam cake is cylindrical inferior gram rods.Loam cake combines by chock 6 and chock hole 2 with lower cover.

Fig. 6 is the lower cover side sectional view of the circular ultrathin lamp box that provides according to embodiment of the present utility model.

With reference to Fig. 6, the superiors are the lamp sheets 7 as picture frame layer, and this lamp sheet 7 is the translucent colloidal materials of one deck, and this material can be printed by wide format printer and go up picture.Reflectance coating 8 is by double faced adhesive tape, and the front is bonded on the LGP 3, and the back side is bonded on the PVC backboard 9, and both are fixed together.PVC backboard 9 mainly plays the effect of a support as base plate.

Fig. 7 is the upper and lower covers wedging structure chart of the circular ultrathin lamp box that provides according to embodiment of the present utility model.

With reference to Fig. 7, the PVC backboard 9 of lower cover has chock hole 2 near peripheral edge portion, and chock 6 inserts in the corresponding chock hole 2, and upper and lower covers just is buckled together, and is combined into integral body.

With reference to Fig. 8, chock 6 radially is formed with the through hole (not shown), thereby makes upper and lower covers in conjunction with more firm by split pin 13 being inserted into described through hole.

Has the of the present utility model circular ultrathin lamp box of structure as mentioned above, its light source aspect: with the soft lamp bar of integrated LED as light source, be covered with around the circular LGP, reflectance coating on the lining of the LGP back side, utilize LGP to meet the principle of anaclasis, line source is become area source, thus uniformly light-emitting.Its frame processing aspect: the frame of ultrathin lamp box plays a part the shading source, for this requirement, the bad solution of traditional handicraft of circular frame, and the utility model is avoided this difficult point, annular shutter plate is bonded on the transparent panel, panel is the acrylic transparent panel of a sheet of planar, cylindrical structural and luminous backboard by the edge combine, realized no mount structure, realized the effect in shading source again, owing to be no mount structure, so when making with the similar round ultrathin lamp box, size can realize arbitrarily, no longer is subjected to the restriction of frame section bar.
