At some special occasions of daily life, the lighting of double-side is often required by people.And the side luminous lighting lamp of current application LGP technology more and more trends towards slimming.
Current, the product that utilizes LGP technology to realize the two-sided bright dipping of ligthing paraphernalia all needs the light element of two groups, i.e. the first light guide plate assembly, the second light guide plate assembly.Utilize two light guide plate assemblies in function, to realize two-sided bright dipping in the solution that realizes the two-sided bright dipping of ligthing paraphernalia no problem, but also exist some problems, need skill upgrading: a. ligthing paraphernalia is comprised of two groups of light elements, and product cost is high; B. adopt two groups of light elements that product thickness is increased.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, and a kind of leaded light module of two-sided bright dipping is provided, and this leaded light module adopts a LGP to realize the effect of two-sided bright dipping, and product structure is simple, can meet the design requirement of slimming, and cost is lower.
A leaded light module for two-sided bright dipping, comprises the first diffusion component, LGP, the second diffusion component that set gradually, and the side of LGP is provided with LED light source; LGP is the first exiting surface near the one side of the first diffusion component, the first exiting surface is provided with a plurality of the first sites, LGP is the second exiting surface near the one side of the second diffusion component, and the second exiting surface is provided with a plurality of the second sites, and described the first site and the second dots staggered are arranged.
Wherein, described the first diffusion component is diffuser plate or diffusion barrier.
Wherein, described the second diffusion component is diffuser plate or diffusion barrier.
Wherein, described the first site is shaped as cylinder, spheroid, hemisphere, centrum or prism.
Wherein, described the second site is shaped as cylinder, spheroid, hemisphere, centrum or prism.
Wherein, described the first site is V-type grooving.
Wherein, described the second site is V-type grooving.
The beneficial effects of the utility model: the LGP two sides of leaded light module of the present utility model is equipped with site, and the dots staggered of two relative exiting surfaces is arranged, both met the two-sided bright dipping of leaded light module, also effectively prevented that the site of exiting surface from impacting the light extraction efficiency of LGP; This leaded light modular structure is simple, can meet the design requirement of leaded light module slimming, and cost is lower.

The specific embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 1 to Figure 3, a kind of leaded light module of two-sided bright dipping, comprises the first diffusion component 3, LGP 2, the second diffusion component 4 that set gradually, and the side of LGP 2 is provided with LED light source 1; LGP 2 is the first exiting surface near the one side of the first diffusion component 3, the first exiting surface is provided with a plurality of the first sites 5, LGP 2 is the second exiting surface near the one side of the second diffusion component 4, and the second exiting surface is provided with a plurality of the second sites 6, and described the first site 5 and the second site 6 are staggered.Two exiting surfaces at LGP 2 all have site.These sites can not impact LGP 2 light extraction efficiencies through special optical design, the site that covers LGP 2 exiting surfaces.This leaded light module is only realized the lighting at two sides effect of whole LGP 2 with a LGP 2, when realizing double-faced uniform lighting function, simplified the structure of lighting, facilitated workman's assembling, simultaneously, the thickness of whole product is thinner, more meets the trend of current the type light fixture slimming development.
Wherein, described the first diffusion component 3 is diffuser plate or diffusion barrier.Described the second diffusion component 4 is diffuser plate or diffusion barrier.
The first diffusion component 3 and the second diffusion component 4 can adopt diffuser plate or diffusion barrier or have other parts of diffusion function, can effectively realize the diffusion of light, and light extraction efficiency is better.
Wherein, described the first site 5 is shaped as cylinder, spheroid, hemisphere, centrum or prism.Described the second site 6 be shaped as cylinder, spheroid, hemisphere, centrum or prism.
The first site 5 and the second site 6 also can be made into other shapes, and its object can realize diffuse reflection.The diffusing characteristic diffuser of site has guaranteed that the light extraction efficiency of finished product is subject to the impact of printed on both sides site very trickle.The first site 5 and the second site 6 can be come by ink printing, chemical attack, laser engraving, injection moulding or other processes, make simple.
