The purpose of this utility model can also be further achieved by the following technical measures.

Preferably, aforesaid lens arrangement, the accommodating LED luminescence unit of wherein said inner chamber.

Preferably, aforesaid lens arrangement, wherein said LED luminescence unit has at least one optical lens layer.

The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, the lens arrangement that the utlity model has diffusion particle at least has following advantages and beneficial effect:

1, easily manufacture and with low cost;

The light that 2, can send LED luminescence unit carries out light harvesting or astigmatism;

Detailed description of the invention

Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to a kind of its detailed description of the invention of lens arrangement, structure, feature and the effect thereof with diffusion particle according to the utility model proposes, be described in detail as follows.

As shown in Figure 1, the present embodiment is a kind of lens arrangement 100 with diffusion particle, and it comprises: body 10; And inner chamber 20.Aforesaid body 10 has multiple diffusion particles 12, and 20 of inner chambers are recessed to form in the bottom surface of body 10.

Aforesaid body 10 can be the poly-sour potassium ester (PMMA by light-permeable, or Merlon (PC Polymethylmethacrylate), Polycarbonate) form, and diffusion particle 12 can be poly-sour potassium ester (PMMA, or Merlon (PC Polymethylmethacrylate), Polycarbonate) or polystyrene (PS, Polystyrene) form.

As shown in Figures 1 and 2, in lens arrangement 100, the bottom surface of body 10 can be smooth plane, the convenient LED luminescence unit 30 covering on a substrate, and with the accommodating LED luminescence unit 30 of inner chamber 20, the lens arrangement 100 with diffusion particle can be combined with LED luminescence unit 30.

Lens arrangement 100 also can elect according to the needs of application, and the light that LED luminescence unit 30 is sent carries out light harvesting or astigmatism.Alternative lens arrangement 100 with light harvesting or astigmatism functions includes convex lens, concavees lens, meniscus or Fresnel (Fresnel) lens etc.

As shown in Figures 1 and 2, the light that the diffusion particle 12 in body 10 can send with LED luminescence unit 30 produces mixed light, and reduces the dizzy phenomenon of Huang that LED luminescence unit 30 produces.

Also can be further in manufacture lens arrangement 100, control the mixed ratio of diffusion particle 12 in body 10, and change printing opacity degree or the mist degree of body 10, and then the change that produces colour temperature while making rays pass through lens structure 100 that LED luminescence unit 30 sends.
