Today Let us see how Test of light transmittance

Test of light transmittance with integrating sphere or Distributed photometric analyzer in Lamps Industry。this step is not use the Lamp housing . And recode the real-time running data.

Then Install bulbs and sockets in the lamp housing.，it’s time again to test.Gets the test result from integrating sphere or Distributed photometric analyzer .

Finally We gained light transmittance Along with the recorded evidence（the relations between the ratio）,

From this may sneak a peek at, different shell of the material and difference. this is call optical loss。

There’s something else going on:

1.   The experiment made with common glass showed that this adhesive has good transparence.( exceeded 92% ) . Super white common glass exceeded 91.5% .but if adopt shell with sand-blasting will decreased 10% . PC lampshade after increased diffusion agent ，the light transmittance at 80 to 86 per cent.

2. The integrating sphere is efficient for test of light transmittance.

3. The user can choose the Lamp housing applying to engineering application by collecting analysis data.

4. After testing , The sample also had to observed grossly .
