LED light diffusion sleeve

LED light diffusion sleeve

Applications:

Used in glass LED tubes for light diffusion. Processing PET light diffusion heat shrink tubing on the glass tube, the product cost, and physical properties are both superior to the traditional PC material. The light diffusion tubing is a new application technology, which can completely replace the traditional PC light diffusion tubing.

Light transmittance

90.0±2.0%

Below 60°C for 10,000 hours, the light transmittance change of the lamp covered with light diffusion tubing is ±2.0%.

Temperature test result

For 10,000 hours, there is no change in YI value and light transmittance.
