1, What are the advantages of LED fluorescent lamp PC cover
From the perspective of cost and performance: PC cheap, PC temperature resistance of more than 100 degrees, suitable for LED fluorescent lamp, PC high transmittance, PC hardness and elasticity, in line with fluorescent lamp requirements, PC cover process, simple process, low processing cost.
The brightness of LED fluorescent lights in shopping malls in particular appears softer and more acceptable. Using cree, wafer chip as light-emitting semiconductor material, placed on the heat dissipation material, and then add high-quality heat dissipation shell and stable and professional power supply, play the role of protecting the internal core, and the ordinary fluorescent lamp shape similar to the lamp tube, can replace the ordinary fluorescent lamp lamp. Guangdong Tianyi Lighting, which develops and produces LED fluorescent lamps in shopping malls, believes that LED fluorescent lamps in shopping malls have such advantages: high luminous efficiency, high color rendering, safety and reliability, green environmental protection and durability, strong versatility, professional and beautiful.
This starts with the material of the PC!! PC is an amorphous engineering material with particularly good impact strength, thermal stability, gloss, bacterial inhibition, flame retardant properties, and contamination resistance. The notched Izod impact stregth of PC is very high, and the shrinkage rate is very low, generally 0.1%~0.2%. PC has good mechanical properties, but poor flow characteristics, so the injection molding process of this material is more difficult. When choosing a quality PC material, it is necessary to take the final expectation of the product as the benchmark. If the plastic part requires high impact resistance, then use a PC material with a low flow rate; Conversely, PC materials with high flow rates can be used, which optimizes the injection molding process.
Make the light of the lamp bead not dazzling, soft, plus dustproof, to protect the lamp bead from being touched.

2, PE lampshade is different from PC lampshade
The production material is different and the environmental properties of the material are different. 1. The production material is different: the PC lampshade is made of PC (polycarbonate) as raw material. PE lampshade is made of silicone as the main raw material. 2. The environmental protection properties of the material are different: the PC lampshade is just ordinary plastic. PE lampshade is environmentally friendly plastic.
