What is the led driver 3 in 1 dimming?

From: www.hzleddriver.com Back to list

LED driver three-in-one dimming refers to LED 0/1-10V dimming, PWM dimming, and adjustable resistor dimming in three ways.
1. LED driver three-in-one dimming: 0/1-10V dimming
The power supply is designed with a control chip. When connected to a 0-10V dimmer, the output current of the power supply can be changed through the 0-10V voltage change. For example: when the 0-10V dimmer is modulated to 0V, the current drops to 0, and the brightness of the light is turned off (with a switch function). 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 be 100%. (The output voltage is unchanged).1-10V dimming principle: As explained above, only the dimmer is 1-10V: when the resistance dimmer is adjusted to the minimum 1V, the output current is also changed by 10%, such as when it reaches 10V (adjusted to the maximum), the output The current will also reach 100% of the power output, and the brightness will also be 100%. (The output voltage is unchanged).
Remarks: 1-10V has no switch function, and the lamps cannot be adjusted to the lowest closing function.
2. LED driver three-in-one dimming: PWM dimming
Digital dimming, also known as PWM dimming, turns on and off LEDs through PWM waves to change the on-time forwarding current to achieve the effect of brightness adjustment. The method is based on the fact that the human eye is not sensitive enough to brightness flickering characteristics, Make the load LED light and dark.
3. LED driver three-in-one dimming: Adjustable resistance dimming
Adjustable resistance dimming is to put a resistor in series in the bulb circuit and change the resistance value to change the loop current to achieve the purpose of dimming.

Hi-zealed LED dimming products will design and match the dimming method according to the lighting application or market demand. If the application is not considered, the advantages and disadvantages of the dimming methods are as follows:

Dimming method	Advantage	Shortcoming
Resistance	Simple control and lowest controller cost	Variable resistors are easily damaged
PWM	Easy to find matching PWM control circuit	Additional wiring is required for lamp ON/OFF control
Triac	Fast voltage regulation, high dimming accuracy and low cost	More prone to EMI problems
DALI	Digital control, the most functions, can be used as a switch control	It needs to be equipped with a dedicated controller, and the cost of the controller is the most expensive
0/1-10V	Simple application, good compatibility, high precision, good dimming effect	High wiring cost

Products with three-in-one dimming functions are as follows:
HZD018CVI
HZD024CVI
HZD036CVI
HZD048CVI
HZD060CVI
HZD048AVI
