As LED lighting products become lighter and thinner, lamps gradually get rid of the dependence on light guide plates. While light diffusion plates help to achieve high light efficiency and high diffusivity of LED lighting, quality requirements such as safety, flame retardancy, environmental protection and weather resistance are also met in certain scenarios. It is proposed that Zhonglan NanoHTM micro-nano high-diffusion plate series introduces single/double-sided microstructure design on the basis of traditional diffuser plates, which further improves the light transmittance and diffusion performance, and can make the thickness of the diffuser plate thinner and more economical. , to further increase the central light intensity and improve the optical efficiency of the lamp.
