Company Development Goals

What is Diffusion Sheet

　　Diffusion sheet is a sheet that interferes with light. No matter what the original designed light distribution curve is, after passing through the diffusion sheet, it becomes 160-176°. There are various types of diffusion sheets on the market, as follows:

　　(1) Air Diffusion Sheet: Generally used to reduce noise caused by airflow. A common example in daily life is the automobile muffler.

　　(2) Sound Diffusion Sheet: Generally used to eliminate echoes caused by hard objects blocking sound. Mainly applied to walls or ceilings in concert halls and KTV.

　　(3) Liquid Diffuser: Generally used to turn liquid into mist or smaller water molecules, allowing uniform distribution. A common application is the water curtain in bathrooms.

　　(4) Odor Diffusion Sheet: Generally used to eliminate or disperse odors, effectively reducing unpleasant smells. Widely used in gas masks or water purifier filter cartridges.

　　(5) Light Diffusion Sheet: Generally used to prevent glare causing visual distraction or eye irritation, creating a comfortable visual environment. Commonly used in camera flash units.

Both diffusion sheet and light guide plate are commonly used sheets, mostly applied in advertising light boxes. Although both are related to light, there are differences between them. Diffusion sheet distributes light uniformly by absorbing the light source, while light guide plate reflects light but does not absorb the light source. If it is just LED direct lighting, only diffusion sheet is needed to scatter the light. However, for light bar type lamp strips, light guide plate is needed to redirect light toward the light source for light distribution.
