How to choose a good quality PC cover?
The quality of the PC lampshade is closely related to the transmittance of the PC lampshade. The high transmittance lampshade can provide ideal luminous flux.
Transmittance of PC cover: At present, the transmittance of the transparent mask of the market can reach 90-95%, and the transmittance of the milky white cover is 70-90%. If a 1.2-meter LED tube, when the bare lamp is lit, that is, without a mask, the measured luminous flux is 2000 lm, and now it is given a transparent mask with a transmittance of only 90%, then it is practical. The luminous flux is only 1800 lm of luminous flux. If you add a transparent mask with a transmittance of 95%, then its actual luminous flux is 1900 lm, which is also a transparent mask. So why is there such a big difference between the two?
The answer is on the material of the lampshade. At present, the material of the PC cover on the market is divided into ordinary PC material and optical grade PC material, and these materials may also have different degrees of light transmittance due to different raw material manufacturers.
The LED lampshade produced by Dongguan Mingmou is made of Japan imported Teijin, Mitsubishi and other materials, and is extruded by the improved process accumulated by itself for many years. The appearance of the mask is smooth and flat, and the roundness is good. There is no obvious step between the PC lampshade and the aluminum component. There are no defects such as scratches, black spots, watermarks, etc., and the surface treatment of the product is very smooth and has a higher light transmittance.
Dongguan mou's PC lampshade has become a supplier of LED fluorescent lamp accessories for many domestic and foreign LED lighting companies due to its high quality, moderate price, prompt delivery and considerate service.
