A kind of LED advertising lamp box
Technical field
The utility model relates to a kind of advertisement cabinet, refers to a kind of LED advertising lamp box especially.
Background technology
Advertising lamp box normally is provided with advertising design on the lamp box surface, in lamp box inside fluorescent tube is set, and lights fluorescent tube during night, can illuminate advertising design from the inside of lamp box, reaches eye-catching effect.In the prior art, the inner light source that adopts of described advertising lamp box is common fluorescent tube or bulb, therefore the light source area of fluorescent tube or bulb is big, and range of exposures is wide, and lamp box is inner generally only need be provided with a spot of several fluorescent tube or bulb promptly can evenly illuminate whole lamp box.But, the power consumption height of fluorescent tube or bulb, operating cost height, and fragile, maintenance cost is high.Because the volume of fluorescent tube or bulb is bigger, and lamp box inside must have enough spaces to be used for holding this fluorescent tube or bulb, the thickness of therefore existing advertising lamp box is bigger in addition, and relatively heaviness also will increase cost.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of power consumption little, and the thin LED advertising lamp box of lamp house thickness.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of LED advertising lamp box, the tank surface of this lamp box is provided with advertising design, and this box house is placed with at least one LED lamp bar according to the casing size, has been spaced some adopting surface mounted LED lamp pearls on the copper platinum lead of this LED lamp bar.
Spacing between adjacent two adopting surface mounted LED lamp pearls of described LED lamp bar is the best with 3mm~6cm.
Described LED lamp bar is provided with two or more, and the spacing between adjacent two LED lamp bars is the best with 3mm~6cm.
After adopting such scheme, because the lamphouse light source that the utility model adopts is LED, and the power consumption of LED is little, long service life, and not fragile, so operating cost and maintenance cost are all lower.In addition, what the utility model adopted is the LED lamp bar that adopting surface mounted LED lamp pearl is made, and this lamp bar only is laminar, so the lamp house thickness of making is thin and volume is little.
In addition, the LED lamp bar that adopting surface mounted LED lamp pearl is made can form standardization, can be cut into random length during installation and arrange, so the shape of lamp box can variation.
Moreover through experiment repeatedly, the spacing of two adjacent LEDs lamp pearl described in the utility model and adjacent two LED lamp bars is arranged to 3mm~6cm, and this spacing only can guarantee bright and clear even, can not produce blackspot, can not increase cost because of spacing is overstocked again.

Fig. 2 is the structural representation of the utility model second embodiment;
Fig. 3 is the structural representation of the utility model the 3rd embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of LED advertising lamp box, as shown in Figure 1, is first preferred embodiment of the present utility model.Described advertising lamp box comprises an elongated strip casing 1 and is arranged at a LED lamp bar 2 of casing 1 inside that this lamp box 1 surface is provided with the advertising design (not shown), has been spaced some adopting surface mounted LED lamp pearls 22 on the copper platinum lead 21 of described LED lamp bar 2.
Because the volume of each LED lamp pearl is less, its light emitting region is less, if arranging of LED is more sparse, blackspot will appear in its lamp box surface, thereby make distribution of light inhomogeneous, if arranging of LED is closeer, and then will ten million waste.For addressing this problem, the spacing between adjacent two adopting surface mounted LED lamp pearls 22 is the best with 3mm~6cm.
Again as shown in Figure 2, be second preferred embodiment of the present utility model.Described advertising lamp box comprises a square box 1 and is arranged at the LED lamp bar 2 of some equal length of casing 1 inside, this lamp box 1 surface is provided with the advertising design (not shown), be spaced some adopting surface mounted LED lamp pearls 22 on the copper platinum lead 21 of described each LED lamp bar 2, and the spacing between adjacent two adopting surface mounted LED lamp pearls 22 is 3mm~6cm.Spacing between adjacent in addition two LED lamp bars 2 is the best with 3mm~6cm also.
As shown in Figure 3, be the 3rd preferred embodiment of the present utility model.Described advertising lamp box comprises a round box 1 and is arranged at the LED lamp bar 2 of some different lengths of casing 1 inside, this lamp box 1 surface is provided with the advertising design (not shown), some adopting surface mounted LED lamp pearls 22 have been spaced on the copper platinum lead 21 of described each LED lamp bar 2, and the spacing between adjacent two adopting surface mounted LED lamp pearls 22 is 3mm~6cm, and the spacing between the two adjacent LEDs lamp bar 2 also is 3mm~6cm.
