6 FAQs about [Old solar powered dimming principle]
How does a 0-10V dimming power supply work?
The 0-10V dimming power supply is designed with a control chip. When connected to a 0-10V dimming device, the output current of the power supply is changed through a 0-10V voltage change to reduce light. For example, when the 0-10V dimmer is modulated to 0V, the current drops to 0, and the light brightness is turned off (with a switch function).
How does PWM dimming work?
The specific method to realize PWM dimming is to connect a MOS switch tube in series with the LED load, and the anode of this series of LEDs is powered by a constant current source. Then a PWM signal is applied to the gate of the MOS tube to quickly switch the string of LEDs. So as to achieve dimming.
How does SCR dimming work?
SCR dimming has been applied in incandescent lamps and energy-saving lamps since its early days, and is also the most widely used dimming method for LED dimming in the current market. Its working principle is to generate a tangential output voltage waveform by chopping the input voltage waveform through the conduction angle.
How does digital dimming work?
Analogue dimming requires a ‘dimming pair’ of cables to be run around to each luminaire in the circuit. This is the simplest option for digital dimming and is operated via a ‘push to make’ or retractive switch, which is then wired to each luminaire in the circuit via a 4 core cable consisting of switched live, neutral, earth and permanently live.
What happens if a 0-10V dimmer is adjusted to 10V?
When the 0-10V dimmer is adjusted to a maximum of 10V, the output current will also reach 100% of the power output, and the brightness will also reach 100% (The output voltage remains unchanged). 0-10V Dimming principle: As mentioned above, the dimmer is only 0-10V.
How to change the brightness of LEDs?
The brightness of the LED can be changed by changing the duty ratio of the constant current source pulse. The specific method to realize PWM dimming is to connect a MOS switch tube in series with the LED load, and the anode of this series of LEDs is powered by a constant current source.
