Method for regulating and controlling LED lamp brightness

The present invention relates to a control method of LED lights, mainly using visual brightness theory and subjective feeling of inertia, LED light response speed, through the adjustment of LED lamp power from 60Hz to 180Hz frequency range control LED lamp voltage pulse control, to achieve control of the LED lighting, and make sure that the LED lamp keep pure white color throughout the dimming range.

The control voltage in a certain frequency range, and method of pulse width in the cycle time by adjusting the working voltage, and can be used for LED lamp to other color of light brightness control while maintaining the basic color does not change the.

The invention solves a difficult problem of LED lamps in the practical application of the brightness adjustment, LED lamp has the very energy saving effect, high luminous efficiency, long service life and no pollution etc. play a greater role in the field of lighting in human.
