PC LED Light Diffuser & Guide | Injection Molded, Uniform Illumination

Product Description

OVERVIEW Precision injection molded PC (Polycarbonate) LED light diffuser and light guide component, engineered to convert point-source LED light into smooth, uniform surface illumination. The part combines optical-grade transparency with controlled light-scattering performance—eliminating hot spots, glare, and visible LED dots while maintaining high total light transmission. MANUFACTURING SPECIFICATIONS • Material: PC (Polycarbonate) – Optical Grade with diffusing additive package • Process: Precision Injection Molding, optimized gate & runner design for symmetric fill • Surface Finish: High Gloss on A-surface; micro-textured or diamond-polished light-exit face • Diffusion Performance: Uniform luminance distribution, no LED dot imaging, low haze gradient • Optical Properties: High total transmission, controlled scattering angle, minimal yellowing • Dimensional Control: Tight tolerance on wall thickness to ensure consistent diffusion effect • Clean Production: Molded and handled in a clean workshop; anti-static, dust-free packaging KEY ADVANTAGES • Uniform Backlight: Scatters LED point light into even panel glow—ideal for indicators and panels. • No Hot Spots: Engineered wall thickness and diffuser formulation remove bright dots and shadows. • High Clarity Base: Maintains PC’s inherent transparency and impact resistance. • Low Stress Optics: Controlled cooling prevents warpage and stress-induced birefringence. • Cleanroom Care: Parts protected from particles and scratches that would show under lit conditions. TYPICAL APPLICATIONS • LED Panel Light Diffusers & Edge-Lit Guides • Backlit Membrane Switches & Keypads • Automotive Ambient Lighting Diffusers • Medical Device Status Indicators & Illuminated Logos • Consumer Electronics Display Covers & Light Pipes • Signage Modules Requiring Even Glow PROCESS NOTE PC resin is thoroughly dried prior to molding to prevent splay. Diffusing agents (silica-based or micro-bead) are pre-compounded for consistent scattering. Gate location is selected to avoid weld lines crossing the active light zone. Mold temperature is stabilized to minimize internal stress and preserve optical uniformity. QUALITY ASSURANCE Inspected under backlit condition for hot spots, flow marks, and haze inconsistency. Dimensional verification on critical optical surfaces. Clean, anti-static packaging. FAIR available; lot-level traceability maintained
