Why Choose Light-Diffusing PC Pellets for LED Lamps? Full Tested Specs & Advantages Uncovered

3D printing and advanced plastic modification technologies have expanded the application of high-performance modified plastics in lighting and electronic devices. Among them, light-diffusing PC pellets—modified from polycarbonate (PC) with light diffusing agents and additives—have become the core material for LED lamp shades and light strips, widely used in indoor lighting, outdoor LED fixtures, and even drone-mounted lighting systems. As a professional modified plastic manufacturer, Qingdao Zhongxinhuamei Plastic Co., Ltd. provides high-quality light-diffusing PC materials with stable parameters and reliable performance, meeting the stringent requirements of diverse lighting application scenarios.

Critical Tested Parameters of Light-Diffusing PC Pellets

The core performance parameters of light-diffusing PC pellets directly determine the lighting effect and service life of lamp products. The actual measured key parameters of Qingdao Zhongxinhuamei’s light-diffusing PC are as follows:

- Haze: 94% – High haze ensures uniform light scattering, eliminating harsh light spots and glare.

- Transmittance: 70% – Balances light diffusion and light utilization efficiency, delivering soft, uniform surface light from point light sources.

- Heat Distortion Temperature (HDT): 125℃ – Excellent high-temperature resistance, suitable for long-term working LED lighting environments.

- Impact Strength: 60 kJ/m² – Superior toughness and impact resistance, preventing damage from accidental collisions during installation and use.

These parameters make light-diffusing PC pellets the optimal choice for manufacturing LED lamp shades and light strips, ensuring both optical performance and structural reliability.

What Is Light-Diffusing PC Material?

Light-diffusing PC material is a modified plastic made from transparent polycarbonate as the base material, blended with light diffusing agents and other additives through special modification processes. Unlike ordinary transparent plastics, it achieves translucent rather than transparent optical properties. When light passes through LED light strips or lamp shades made of light-diffusing PC, it undergoes multiple refraction, reflection, and scattering, converting point light sources into soft, uniform surface light. This effectively avoids strong light spots and glare, providing a comfortable visual experience for users.

Core Advantages of Light-Diffusing PC for Lighting Applications

1. Superior Mechanical Performance

Light-diffusing PC material features high strength and excellent impact resistance. It is not easily cracked even under moderate external collisions, ensuring the durability of light strips and lamp shades during installation, transportation, and daily use—thus extending the service life of LED lighting products.

2. Excellent Weather Resistance

The material exhibits outstanding resistance to high temperature, low temperature, humidity, and UV radiation. It resists aging, discoloration, and brittleness degradation under harsh outdoor conditions, making it ideal for drone-mounted lighting systems and outdoor LED fixtures that require long-term stable operation.

3. Stable Optical & Batch Performance

Light-diffusing PC has pure color, good base color, and high transmittance, with vivid color expression. Its high haze effectively softens light without dazzling, and the black spot level reaches A+—ensuring high product yield in mass production. Additionally, the material maintains stable color and performance across batches, and can be customized according to customer-specific lighting design needs.

4. Durability & Anti-Yellowing

PC resin itself has good flexibility and long-term stability, and light-diffusing PC pellets retain these properties without yellowing even after long-term use, ensuring the consistent appearance and performance of lighting products over time.

Why Light-Diffusing PC Is a Must for LED Lamps & Light Strips

The fundamental goal of lighting design is to achieve uniform light emission for optimal illumination. Ordinary transparent PC materials transmit light in a straight line, resulting in uneven lighting, harsh glare, and poor visual comfort. In contrast, light-diffusing PC scatters light in all directions through the action of diffusing agents, realizing uniform light diffusion and distribution. This not only meets the lighting effect requirements but also provides greater design freedom for LED lamps, enabling creative shapes and layouts without compromising light uniformity.
