Introduction of LED ceiling lamp shade

     LED ceiling lamp shade commonly used is the PC board, its performance is as follows:
     Translucent: PC board transmittance up to 89%, with the glass is almost. UV coating plate in the sun exposure will produce yellowing, atomization, poor light transmission, ten years after the transmission loss is 6%, PVC turnover rate is as high as 15%~20%, glass fiber 12%~20%.
     The anti impact: PC plate impact strength is 250-300 times of ordinary glass. 30 times the same thickness of acrylic sheets. Is 2-20 times of toughened glass. Have the laudatory title of "not broken glass" and "ring of steel".
     Anti UV: PC board side is coated with anti ultraviolet (UV) coating, the other side has the anti condensation process, anti ultraviolet, set insulation anti fogging functions. UV blocking through, for protecting the valuable works of art exhibits, make it from UV damage.
     Light weight: LED ceiling light shade adopts PC board, the proportion is only half of the glass, saving transportation, unloading, installation and support frame of cost.
     Flame retardant: PC board ignition is 580 degrees Celsius. Away from the fire extinguished, does not produce toxic gases when burned, will not contribute to the spread of fire.
     The temperature adaptability: PC plate in -100 ℃ no cold crisp, not soft in 135 ℃, its mechanics in harsh environments, such as mechanical properties showed no significant changes.
     Weathering: the stability of PC plate can maintain the physical indicators at - 40 ℃ to 120 ℃ range. Artificial weathering test 4000 hours, yellowing degree is 2, transmittance reduce value is only 0.6%.
