Tube Light Diffuser Sheet is a light diffusion material designed for linear light sources such as fluorescent tubes and LED tubes. The main materials are high-quality polycarbonate (PC), polypropylene (PP) or polymethyl methacrylate (PMMA), which optimizes the uniformity of light illumination, prevents glare, scatters dazzling light sources, and enhances the integrated design of the appearance of the lamp.
The standard size is 1200*1000000mm, the coil Diameter is 650mm

Tube Light Diffuser Sheet adopts microstructure diffusion technology, and the light transmittance can reach 80%-88%, while the haze is controlled between 70%-85%, ensuring soft and even distribution of light, effectively eliminating the dot-like feeling of LED lamp beads. It is suitable for common lamp models such as T5 and T8, which can significantly improve the lighting comfort and reduce visual fatigue.
Tube Light Diffuser Sheet uses UL94 V-2 or V-0 grade flame retardant materials, has excellent heat resistance, long-term working temperature can reach 110℃, short-term can withstand up to 135℃, adapt to high temperature closed lighting environment, ensure safe use.
Compared with traditional glass diffusers, Tube Light Diffuser Sheet is lighter, only 1/10 of glass, easy to install, and reduces transportation costs. Its impact resistance is excellent, the impact strength of PC diffuser is more than 20KJ/m², even if it collides during transportation or installation, it is not easy to break, enhancing safety.
Support customized size and structure design according to customer needs, such as thickness 0.8mm, 1.0mm, 1.2mm, 1.5mm and other specifications are optional, width supports up to 600mm, surface texture can choose fine frosting, pearlescent surface or smooth surface to meet different appearance and optical needs.
The Tube Light Diffuser Sheet material is modified with UV stabilizers and has good UV resistance. It is not easy to turn yellow after long-term use. After 500 hours of exposure in the UV test machine, the yellowing index ΔYI <3, which extends the overall service life of the lamp and maintains high light transmittance.
In the lighting design in modern office buildings, Tube Light Diffuser Sheet is widely used in linear LED lamps and embedded tube devices. Its superior light diffusion performance can create a soft and bright working atmosphere, improve employee concentration and comfort, reduce interference caused by flicker and glare, and meet the LEED green office space standards.
In sanitary environments such as hospitals and clinics, Tube Light Diffuser Sheet is used to replace T8 LED lamps to ensure that the lighting is flicker-free and glare-free, and high fog dispersion technology is used to avoid strong light directly hitting the patient's eyes and protect eyesight. The materials used are non-toxic and environmentally friendly, meeting the RoHS and REACH regulations of the medical industry.
The public transportation system has extremely high safety requirements for lighting equipment. The anti-shattering and high flame retardancy of Tube Light Diffuser Sheet make it outstanding in the protection of subway lamp tubes. It is especially suitable for linear lights on the top of subway cars and platform guide lamps to prevent passenger risks caused by accidental shattering of lampshades.
In large retail spaces, such as supermarkets and convenience stores, Tube Light Diffuser Sheet is used in shelf lights and ceiling track light systems. Its high light transmittance and uniform diffusion ability can ensure the true color restoration of goods, improve the shelf display effect, and enhance consumers' willingness to buy.
In school classrooms and laboratory lamps, Tube Light Diffuser Sheet helps create a learning light environment without glaring spots. The milky white diffusion surface evenly outputs soft light, which helps reduce students' eye fatigue, supports efficient reading and writing around the clock, and meets the UGR control requirements of the national standard for educational lighting.
