Constant current driver
A constant current driver is a type of driver that provides a constant current for LEDs. Its working principle is to automatically adjust the output current based on the voltage current characteristics of the LED to maintain stable brightness. Constant current drivers are commonly used in situations that require stable brightness, such as lighting applications.
Features:
High stability: The constant current driver can maintain a stable output current when the input voltage or LED parameters change, thereby ensuring the brightness stability of the LED.
Strong protection: Constant current drives usually have functions such as overcurrent protection and overvoltage protection, which can effectively protect LEDs from damage.
Wide applicability: The constant current driver is suitable for various LED lighting scenarios, such as indoor lighting, outdoor lighting, etc.
Application:
Street lighting: Street lighting requires stable brightness and long-term operation, and a constant current driver can meet these requirements.
Display screen: LED display screens require consistent brightness of each LED pixel, and constant current drivers can ensure stable brightness of each LED pixel.
Indoor lighting: Indoor lighting requires soft and stable lighting, and a constant current driver can provide a stable light source.
Constant voltage driver
A constant voltage driver is a type of driver that provides a constant voltage to LEDs. Its working principle is to adjust the output current of the LED according to its voltage current characteristics under a certain output voltage, in order to maintain the brightness stability of the LED. Constant voltage drivers are usually used in situations that require LED series drive or require adjustable brightness.
Features:
High flexibility: The constant voltage driver can adapt to different numbers of LED series drives and flexibly adjust brightness.
High power factor: Constant voltage drives can usually achieve high power factor and improve energy utilization efficiency.
Strong adjustability: The constant voltage driver can achieve LED dimming function by adjusting the output voltage or current.
Application:
LED backlight: LED backlight requires adjustable brightness, and the constant voltage driver can adjust the backlight brightness by adjusting the output current.
Automotive lighting: Automotive lighting needs to adapt to the brightness requirements of different working environments, and constant voltage drivers can flexibly adjust the brightness of LEDs.
Decorative lighting: Decorative lighting situations usually require LEDs of different colors and brightness, and constant voltage drivers can achieve multiple LED series drives to meet different decorative effects.
