Manufacturer Supply Heat Resistant Light Diffusion PC for LED Lamp Covers

Glare, uneven light spots and inconsistent brightness from point light sources are long-standing pain points for LED lamp manufacturers during popularization. Light diffusion PC is the top optical material for LED lamp covers, housings and backlight panels, widely adopted in residential lighting, commercial lamps, vehicle indicator lights and translucent home appliance panels thanks to its balanced high light transmittance, high haze, outstanding heat resistance and impact resistance.

A standard 2.0mm light diffusion PC sample delivers 70%–90% visible light transmittance with adjustable haze up to 99%. Multi-layer refraction and scattering convert harsh point light into soft, uniform surface light, eliminating glare while maintaining high luminous efficiency. Its infrared transmittance exceeds 90%, making it suitable for special optical lighting products. The material features pure, spot-free base color and strong anti-yellowing performance under long-term high-temperature operation. Transmittance, haze and fluidity are fully customizable to match lamp shapes and application scenarios; PC, PMMA and PS base resins are optional to balance performance and costs.

Beyond premium optical performance, this material boasts stable mechanical and thermal properties: tensile strength hits 60 MPa with 90% elongation at break, and superior impact resistance far outperforms glass and ordinary acrylic, cutting breakage risks during transportation and installation with lightweight design. Its heat deflection temperature reaches 125°C and Vicat softening point 145°C, resisting deformation under sustained LED operating heat. A stable molding shrinkage rate of 0.4%–0.6% ensures high dimensional precision for complex curved lamp covers, long light boxes and instrument translucent shields.

Qingdao Zhongxin Huamei Plastic Co., Ltd. develops and mass-produces light diffusion PC for indoor and outdoor lighting. Our mature production process raises finished lamp yield by ~5% and boosts overall processing efficiency by over 50%. The material fits downlights, bulb lamps, street lights, display backlight panels, automotive indicator covers and more.
