Projector light output



Projector light output

Refers to the light energy output by the projector, in units of "lm", and the light output of a physical quantity is brightness, refers to the screen surface by light irradiation emitted light energy and screen area ratio, brightness unit commonly used is "lx, 1lx = 1lm / m2 ". When the projector output light through a certain time, the greater the projected area, the lower the brightness, on the contrary, the higher the brightness. The factors that determine the projector's light output are projection and screen area, performance and lens performance, usually fluorescent screen area, light output. Projector with liquid coupling lens lens performance, the projector light output can be increased accordingly
