1, reflective glass works
Light emitted from the light irradiated to the reflecting surface of the reflector cup after reflection, the reflected along the propagation direction. Change the light reflective curved surface is actually the original propagation direction so that the light emitted by the light source is reflected to the direction of propagation according to the demand, so that the effective use of reflector light on the role played.


2, the spatial distribution of light source
Reflector is a reflected light of the device, the different light sources, reflector curve is different, because the light emitted from the different light distribution in space is different, can not use the same reflector to different sets of light sources. The light source is in the spatial distribution of light intensity or illumination to express, through the instrument to be measured by looking at the source of the distribution curve can roughly understand the spatial distribution of light energy situation.


Photometric light
3, the reflection curve complicated calculations required to control the light in a different position to reach the required reflection direction of light propagation.
