Abstract
The utility model relates to an illuminating light source for an outdoor indicating board, in particular to a waterproof Illuminating light source for outdoor indicating boards, which comprises an LED light set arranged on a planar light guide plate. Diffusing sheets are arranged on the front surface of the planar light guide plate. The illuminating light source for the outdoor indicating board substitutes for the traditional fluorescence tubes high in power consumption and serves as an illuminating light source for outdoor indicating boards, and power resource can be better saved. Furthermore, waterproof effect can be achieved by arranging an outer casing and filling clearance with waterproof glue.
Description
Technical field
The utility model relates to a kind of outdoor direction board lighting source, particularly a kind of waterproof outdoor direction board lighting source.
Background technology
Outdoor bus stop plate or direction board when indicating night, need be provided with light source and set the power supply power supply, and the bus stop plate of existing open air or direction board adopt fluorescent lamp as light source usually, and power consumption is big.And, also have the requirement of waterproof as the lighting source of direction board because environment for use is abominable.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of novel outdoor direction board lighting source, and power consumption is low, environmental protection.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:
A kind of outdoor direction board lighting source, its difference are, include LED lamp group, and described LED lamp group is arranged on the plane LGP.
Further, be provided with diffusion sheet in LGP front, described plane, the back side is provided with reflector plate.
As to improvement of the technical scheme, be equipped with waterproof case in diffusion sheet, reflector plate outer periphery.
Further, described waterproof case comprises the transparent outer cover of diffusion sheet front side, the PVC bottom of reflector plate rear side, and the bar shaped sealed frame of the band groove that sets all around.
The utility model replaces traditional big fluorescent tube of power consumption, as the lighting source of direction board, has better saved electric power resource.Simultaneously, by setting shell, to reach good waterproof effect.
Description of drawings
Fig. 1 is the preferred embodiment schematic diagram of the outdoor direction board of the utility model with lighting source
Fig. 2 is the cross-sectional structure schematic diagram of Fig. 1.
The specific embodiment
Understanding and realization the utility model for the ease of persons skilled in the art are further described embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Figure 1 is a preferred embodiment of the present utility model, and Fig. 2 is its cross section structure schematic diagram.As shown in Figure 1 and Figure 2, outdoor direction board of the present utility model includes with lighting source and is shaped as rectangular LGP 4, fixedly be installed on LED lamp group 5 at LGP 4 two ends by pcb board 6, be pasted with double faced adhesive tape 3 in LGP 4 both sides, positive with it respectively reflector plate 7, the diffusion sheet 2 at the back side are adhesively fixed, and the film 1 between diffusion sheet 2 and the LGP 4 is used to block the light that LED lamp group 5 is sent forward.Described LED lamp group 5, reflector plate 7, LGP 4, diffusion sheet 2 are formed a LED backlit display.
In the utility model, front end is equipped with transparent outer cover 8 in the front of LED backlit display, and the rear end is equipped with PVC bottom 9, be equipped with the bar shaped sealed frame 10 of band groove 11 all around, form waterproof case, the whole LED backlit display screen is coated, wherein slotted section adopts marine glue to fill.
Energy-saving effect of the present utility model is very obvious.A common billboard that size is 300MM*200MM, it uses one of fluorescent tube, and its power is 20W; Adopt the utility model to reach effect same, only need to use 120 on LED lamp, employing 12V's is backlight, because the voltage of simple grain lamp is at 2.8～3.3V, can carry out 3 groups of series connection and add resistance again, power is 0.02W, again 40 groups of parallel connections, general power is 40*0.02=0.8W, and its power consumption only is 1/25 of a traditional tube power consumption.
The utility model application is extensive, partly makes the billboard of doing with light pipe, street lamp board etc. before can effectively substituting.Simultaneously, by setting shell, to reach good waterproof effect.
Below only be preferred forms of the present utility model, not in order to restriction the utility model.All according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into protection domain of the present utility model.
