Current Control
controls the current flows into the Lamp,
a certain frequency, and
Current Control (Analog Dimming)
- Dimming is possible with almost no influence upon the Panel
- The Minimum Current enough to have no partial Lamp off/on is needed in the Minimum Brightness
- Low Dimming Ratio (nearly 2 : 1)
- Low Efficiency in Dimming State because of the Condition of Inverter is optimized to the Maximum
Brightness
PWM Control (Burst Dimming)
- Dimming by turning the Lamp off/on with about 300Hz ~ 1kHz frequency
- Water Fall is found because of the Noise and the Panel power's unstable Ground according to Current
on/off in certain period
- High Efficiency because the IP Board always operated in the Maximum Brightness whenever the Lamp
is on
- Cleat up the partial Lamp off/on issue in the Minimum Brightness
(Dimming Ratio (nearly 5:1))
Complex Control
- Suppress the occurrence of Water Fall by using the Analog Control in the early stage of Dimming
- Improve the Dimming Ratio by using the PWM Control in the late stage of Dimming
Complex Control
is the mixture of Current Control and PWM Control.
PWM Control
controls the Lamp off/on with
