Abstract
The utility model relates to an optical diffusion plate. The optical diffusion plate is characterized in that the optical diffusion plate comprises a first layer, a second layer and a third layer which are sequentially arranged, wherein the first layer is polymethyl methacrylate; the second layer is a bonding layer; and the third layer is polycarbonate. In the optical diffusion plate, a transparent and flame-retardant PC (polycarbonate) plate and a PMMA (polymethyl methacrylate) optical diffusion film are compounded together to form a composite film; by fully utilizing the optical diffusion effect of the PMMA optical diffusion film, gentle light can be provided; and meanwhile, the transparent and flame-retardant PC plate provides high mechanical strength and flame-retardant property for the composite film. Therefore, compared with the optical diffusion plate in the prior art, the optical diffusion plate disclosed by the utility model has the characteristics of favorable flame-retardant property and mechanical strength.
Description
Technical field
The utility model relates to a kind of light diffusing sheet.
Background technology
Need to be to use glass traditionally in the occasion of light transmission device at some, arrive observer's eyes thereby light source is emitted beam.As shown in Figure 1, the light that light source 4 sends, through behind the glass 5, shine in observer's the eyes 6, in this case, observer's eyes 6 are experienced passes only a branch of very strong light that described light source 4 sends, and the light that this bundle is very strong only is positioned at the part zone of whole glass, thereby cause whole glass to produce light, dark clearly demarcated phenomenon, in addition, the observer can also see light source 4.
In order to solve above-mentioned deficiency, adopt single PMMA(Polymethyl Methacrylate, polymethylmethacrylate in the prior art usually) or PC(Polycarbonate, polycarbonate) as light diffusing sheet.As shown in Figure 2, light beam that light source 4 sends is through behind the light diffusing sheet 7, send from the opposite side of overall optical diffuser plate 7, therefore, observer's eyes 6 are seen be soft, be evenly distributed on the light on the overall optical diffuser plate 7, and the observer can't see light source 4.
Yet the shortcoming that acrylic has is more crisp, anti-flammability is bad; The PC material then has the bad shortcoming of weatherability.
Summary of the invention
The purpose of this utility model provides a kind of good flame resistance, light diffusing sheet that mechanical strength is high.
For solving the problems of the technologies described above, the utility model is taked following technical scheme: a kind of light diffusing sheet is characterized in that: described light diffusing sheet comprises the ground floor that is arranged in order, the second layer and the 3rd layer; Described ground floor is that polymethylmethacrylate, the described second layer are bonding coats, and described the 3rd layer is polycarbonate.
Further, described ground floor is the optical diffusion film that polymethylmethacrylate is made.
Further, described the 3rd layer is the sheet material that polycarbonate is made.
Thereby the utility model is combined with each other the PC sheet material of transparent flame-retarding and PMMA optical diffusion film and forms composite membrane, made full use of the light diffusion effect of PMMA optical diffusion film, thereby can provide soft light, simultaneously, the PC sheet material of transparent flame-retarding provides high mechanical strength and anti-flammability to described composite membrane.Therefore, the light diffusing sheet in the utility model compare with light diffusing sheet of the prior art have anti-flammability, characteristics that mechanical strength is good.

Fig. 2 is the diffusion synoptic diagram of light when passing through light diffusing sheet.
Fig. 3 is the structural representation of the light diffusing sheet in the utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
Fig. 3 shows the structural representation of the light diffusing sheet in the utility model.As shown in Figure 3, the light diffusing sheet in the utility model comprises that the described light diffusing sheet that is arranged in order comprises the ground floor 1 that is arranged in order, the second layer 2 and the 3rd layer 3; Wherein, described ground floor 1 is PMMA(Polymethyl Methacrylate, polymethylmethacrylate), the described second layer 2 is bonding coats, described the 3rd layer 3 is PC(Polycarbonate, polycarbonate).The described second layer 2 is used for described ground floor 1 is bonded into one with described the 3rd layer 3.
Preferably, described ground floor 1 is the optical diffusion film that PMMA makes.
Preferably, described the 3rd layer 3 is the sheet material that transparent, fire-retardant PC makes.
Thereby the utility model is combined with each other the PC sheet material of transparent flame-retarding and PMMA optical diffusion film and forms composite membrane, made full use of the light diffusion effect of PMMA optical diffusion film, thereby can provide soft light, simultaneously, the PC sheet material of transparent flame-retarding provides high mechanical strength and anti-flammability to described composite membrane.Therefore, the light diffusing sheet in the utility model compare with light diffusing sheet of the prior art have anti-flammability, characteristics that mechanical strength is good.
Claims (3)
