PWM is the abbreviation of Pulse Width Modulation, and
refers to the method of controlling signal intensity by
controlling the ratio between the ON period and OFF period
of a pulse signal.
A pulse signal is a signal which repeatedly alternates
between ON and OFF, and the percentage of ON period
during a single cycle is referred to as the "duty cycle".
PWM-controlled lighting is a method for controlling the
brightness of a lamp by controlling the duty cycle (lit time) of
light from a pulse-emission source. As the lit time becomes
longer, the light becomes brighter, and conversely, as the lit
time becomes shorter the light becomes darker.
Period when LED is lit
Multi-point measurement and CCF calibration
possible
Measurements of up to 30 points can be controlled. A CCF
(Color Correction Factor) function is also provided to enable
calibration to user standards.
