LED T8 luminaire lighting cover
Jan 08, 2019

The outer cover is basically a PC cover, and substantially no glass cover is used. They are all made from PC pellets (chemical name: polycarbonate) and then mixed with diffusion powder.

The PC cover can be divided into a transparent cover, a transparent stripe cover, a diffuse stripe cover (our company called: a thick stripe cover), and a milky white diffuser.

Transparent cover: Gu Ming, the transparent cover is a transparent PC cover. The lamp made by this cover can see the lamp bead, it is very glaring, easy to stun, and does not meet the human requirements for light. The light transmission performance is good, and the light transmittance of 91% can be achieved.

Transparent stripe cover: This kind of cover is a translucent cover that can spread the light, but the light is not even enough, it will not be glaring, and the light transmittance is about 88%.

Diffusion stripe cover: Also known as a thick stripe cover, this case has a light transmittance of about 86%. The product made by this case does not seem to have a dark area, and the dark area is ingeniously avoided.

Milky white diffuser: This cover is also the cover used by most manufacturers on the market. The general transmittance of this case is 83-85%; the light transmittance below 83 is that the spot of the lamp is completely invisible.
