ALD-605012P * 131
Determines maximum value for output current in analog modulated light, to enable brightness control at that range, using PWM modulated light.
<Modulated Light Example 1 (gray in diagram below)>
Set output current value to 100%, in cases where PWM modulated light is desired at a modulated light range of 100% to 0%
<Modulated Light Example 2 (black in diagram below)>
Set output current value to 50%, in cases where PWM modulated light is desired at a modulated light range of 100% to 0%
Analog modulated light is the modulated light system for changing current amplitude. The benefits this system offer are that low
frequency noise hardly occurs because it does not have an intermittent action and input power source load is small because
input current variation is small. Conversely, because it changes the LED action point, chromaticity varies according to the
modulated light.
PWM modulated light is the system where intermittent actions are made at low frequency in the range of 100kHz to 1kHz, and
this on duty is varied to modulate light. Although this system leaves concern about low frequency noise and the demand for
excessive answering to accommodate input power source, it offers the benefit of small chromaticity variations according to
the modulated light because the LED action point does not change. PWM modulated light comes in two forms: a built-in PWM
modulated light system (this is inside the LED driver generating chopping and sawtooth waves, which are compared against
the external DC voltage to form a modulated light pulse) and an external PWM modulated light system (this directly applies the
pulse from outside to modulate light).
The ALD Series combines analog modulated light and PWM modulated light to enable the generation of modulated light that
suits your needs.
