The glass lamp shade is good still the PC lamp shade is good
Chimney has good light penetration, high temperature gas free play, not yellow, weather resistance, high light transmittance, can choose the internal and external coating, grinding, vacuum coating, grinding aluminum plating, electrostatic spraying, spraying color shading technology. It is suitable for interior decoration and lighting. Now high-end LED indoor lamps and lanterns have adopted glass lamp shade. Disadvantages: the advantages of fragile PC lamp cover:
Less than glass products light weight (density), non-friable (bad), produced by imported material with PC 5-10 years basic don't change color, color variety, anti-aging, gelation-flow-casting method (wind, snow and ice impact resistance). It is the first choice of large square, main road, central park and landscape lamp. Disadvantages: low rigidity and flexible weakness. Fully transparent PC lampshades can cause blinding or dazzling strings in the center of a light source, but the brightness in the periphery of the light source quickly decreases. A lot of social situations and the lighting of the work environment have to rule out this unpleasant atmosphere or minimize the source of light that causes discomfort. PC heat deformation temperature is 90 degree, when using a PC lamp shade, often must consider increase the distance of light source and lamp shade or reduce the output power of the light source.
The light of glass is good, it looks crystal clear, the light of the light of the PC is bad, look hazy and faint.
