How to distinguish the LED panel light diffusion plate and light guide?
LED panel light diffusion panel is light in the forward process to penetrate the scattering phenomenon caused by the other medium so, as long as two different medium light from A to B will cause caused by the refractive index or interfere with material blocking light transmission or reflection or absorption, penetrating part is dispersion is the so-called light diffusion, it exists three physical phenomena.Functional aspects of the difference between:
Diffusion plate main function is: 1, the scattered light flux, let the light evenly distributed (part of the composite in addition to the light diffuser homogenization, also can control the emergent Angle; 2, support the backlight architecture, under the protection of optical material damage.
Main effect of light guide plate is: 1, to guide the luminous flux LED panel light point light uniform distribution within the whole face. His key role is to guide the distribution of light; 2, the use of reflection mechanism more efficient us
