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.
