Liquid crystal self-regulation system of exporting fixed light intensity
In order to control the light intensity of a certain environment
a liquid crystal self-regulation system of exporting fixed light intensity is put forward and its principle and functions is also studied. First
the electric-optic modulation principle using liquid crystal and the control principle of photoelectric sensor and single-chip microcomputer are introduced. Then
the exploitation of this system is illustrated and the configuration and the operating principle of every module are introduced in detail. This system has four functions as follows:maintaining light intensity invariant in a specific space; adjusting light intensity in a given space; displaying the current working state; testing the liquid crystal's electro-optical curve. This system is suitable for the constant light intensity environment and the constant temperature system which makes use of light energy.
