What are the advantages of the materials used in LED lampshades?
The LED lampshade disperses the PC material, the light utilization rate of the bulb is increased to 92%, and the broken and tolerance problems of the lampshade are reduced to 100%. Because the PC material itself is tough, UV-resistant, and easy to produce by injection molding, the tolerance can be controlled to 0.02mm.
The light dispersion LED lampshade is made of PC material with nano-scale light-guiding molecules, which can make the light transmittance reach 94%. At the same time, the material can be injected into any shape and size through mold design, which is a major breakthrough in the LED lampshade industry in the world today. .
The LED lampshade adopts the glass sprayed dome cover, because the glass bulb has many shortcomings in the material itself, such as the tolerance is too large, fragile, and the packaging cost of the long-distance transportation increases, but the most important thing is that the light efficiency utilization rate is too low, the light Lost up to 30%.
LED lampshade polycarbonate, referred to as PC. PC is an amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastic with excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, flexural strength and compressive strength; Small creep, stable size; excellent heat resistance and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties and flame retardancy in a wide temperature range, and can be used at -60~120 °C It can be used under high temperature for a long time; there is no obvious melting point, and it is in a melting state at 220-230 °C; because of the high rigidity of the molecular chain, the viscosity of the resin melt is large; the water absorption rate is small, the shrinkage rate is small, the dimensional accuracy is high, the dimensional stability is good, and the film is breathable Low resistance; self-extinguishing material; stable to light, but not resistant to ultraviolet light, good weather resistance; oil resistant, not resistant to acid, not resistant to strong alkali, oxidizing acid and amines, ketones, soluble in chlorinated hydrocarbons and aromatics A group of solvents, it is easy to cause hydrolysis and cracking in water for a long time. The disadvantage is that it is prone to stress cracking due to poor fatigue resistance, poor solvent resistance, and poor wear resistance.
