Selecting Power Supplies for LED lighting

Pulse Light Control System

Controlling the brightness by changing the pulse width.

Advantage

When turning on, the light luminance is relatively uniform because it is unlikely affected by the fluctuation of Vf of the element. It has a longer operating life than contumuous lighting using the voltage light control because it turns on/off at a high speed.


Disadvantage

A camera with an ultra high-speed shutter may get dark when it synchronizes with the shutter.
The noise is likely to occur.


Pulse Light Control System

Voltage Light Control System

Controlling the brightness by changing the voltage

Advantage

It is unlikely that a camera may get dark when it synchronizes with a shutter in the same way as with the puls light control power supply.


Disadvantage

The light luminamce can not be unirom because the fluctuation of Vf of the element affacts significantly.
