Subdued light board used for LED (Light Emitting Diode) and preparation method thereof

The invention discloses an anti-dazzle subdued light board used for an LED (Light Emitting Diode) to reduce blue light hazard, and a preparation method thereof. The subdued light board used for the LED is prepared from the following ingredients in parts by weight: 97.8-98.9% of subdued light board base material, 1.0-2.0% of amine resin light diffusant and 0.1-0.2% of stress slow-release agent. The amine resin light diffusant is added into a mixture of at least one or at least two types of GPPS (General Purpose Polystyrene), PC (Poly Carbonate), PMMA (Polymethyl Methacrylate) or PET (Polyethylene Glycol Terephthalate), and therefore, the anti-dazzle subdued light board has the effects of dazzle prevention and blue light reduction. After the stress slow-release agent is added, a stress concentration phenomenon generated since the base material and the light diffusant have different shrinking percentages can be eliminated. 本发明公开了种防眩光和减少蓝光危害的LED用柔光板及其制备方法。所述LED用柔光板的组成及各组分质量百分比为：柔光板基材97.8~98.9%，氨基树脂光扩散剂1.0~2.0%，应力
