LED light diffusion sleeve

LED light diffusion sleeve

Applications:

Used in glass LED lamp casing engineering, processing the PET light diffusion sleeve on the glass tubes, makes cost and physical properties both superior to the traditional PC material. Light diffusion sleeve is a brand new application and technology, it can perfectly replace the traditional PC light diffuser.
