LED ceiling light shade

The LED ceiling lamp shade usually uses PC board, and its performance is as follows:

(1) Light transmittance: The light transmittance of PC board can reach up to 89%, which is as beautiful as glass. UV-coated panels will not produce yellowing, atomization and poor light transmission under sunlight. After ten years, the loss of light transmission is only 6%, the loss rate of PVC is as high as 15%-20%, and the glass fiber is 12 %-20%.

(2) Impact resistance: The impact strength of PC board is 250-300 times that of ordinary glass, 30 times that of acrylic board of the same thickness, and 2-20 times that of tempered glass. There will be no cracks even when it is dropped two meters under a 3kg hammer. The reputation of "unbreakable glass" and "sound steel".

(3) Anti-ultraviolet: One side of the PC board is coated with anti-ultraviolet (UV) coating, and the other has anti-condensation treatment, which integrates anti-ultraviolet, heat insulation and anti-drip functions. It can block ultraviolet rays from passing through, and is suitable for protecting valuable artworks and exhibits from ultraviolet rays.

(4) Light weight: the specific gravity is only half of that of glass, saving the cost of transportation, handling, installation and supporting frame.

(5) Flame retardant: The national standard GB50222-95 confirms that the PC board is flame-retardant grade one, that is, grade B1. The ignition point of the PC board is 580 degrees Celsius, and it will self-extinguish after leaving the fire. It will not produce toxic gas during combustion and will not promote the spread of fire.

(6) Flexibility: Cold bending can be used on the construction site according to the design drawing, and it can be installed into an arch, semi-circular roof and window shape. The minimum bending radius is 175 times the thickness of the adopted plate, and hot bending is also possible.

(7) Temperature adaptability: PC board will not be cold brittle at -100℃, and will not be softened at 135℃, and its mechanics and mechanical properties will not change significantly in harsh environments.

(8) Weather resistance: PC board can maintain the stability of various physical indexes in the range of -40℃ to 120℃. After 4000 hours of artificial weathering test, the yellowing degree was 2, and the light transmittance decreased by only 0.6%.
