Description

Technical Field

[0001] The utility model relates to the technical field of LED lighting, and specifically, to a DALI-controlled constant-voltage-to-constant-current four-channel dimming and color-tuning controller. Background Art

[0002] Constant-voltage-to-constant-current multi-channel dimming and color-tuning means switching the LED strip control system from a constant-voltage mode to a constant-current mode, and having multiple channels to control the brightness and color of the strip. Such a control system is usually used in LED lighting systems, especially in occasions where precise control of color and brightness is required, such as stage lighting, film and television lighting, and decorative lighting. In such a system, the constant-voltage mode means that the LED strip operates at a certain voltage, while the constant-current mode means operating at a certain current; by adjusting the current, the brightness of the LED can be precisely controlled and the brightness of the LED can be kept stable and unchanged, even if the voltage of the LED changes, it will not affect its brightness; and the dimming and color-tuning function is to adjust the brightness and color of the LED by controlling the current of different channels, so as to realize the adjustment and control of the LED lighting.

[0003] Although the constant-voltage-to-constant-current multi-channel dimming and color-tuning control system has powerful functions and wide adaptability, it also faces challenges such as complexity in design and implementation and high costs. Therefore, in specific applications, reasonable trade-offs and designs need to be made according to actual requirements and resources.

[0004] For example, Chinese Patent CN219204749U discloses a lighting controller circuit, including a CPU main control unit U3, a 5V power supply module, a 20V power supply module, an embedded DALI power supply module, a DALI communication unit, and a 0-10V dimming and color-temperature dual-channel output unit, which meets the requirements of stable and high-precision 10V dimming and also meets the requirements of high efficiency and anti-interference of the 5V main control power supply. However, in the process of specific application of the above lighting controller circuit, there are the following deficiencies: the cost of the driver and controller used is higher than that of a simple constant-voltage system; the dimming of the 0-10V dimming and color-temperature dual-channel output unit generally uses PWM dimming, which may cause noise and flicker problems; at the same time, the 0-10V dimming and color-temperature dual-channel output unit needs to be individually debugged and calibrated for each channel, and the debugging workload is large and complex; in addition, since different brands and types of LEDs may have different requirements for current and voltage, it needs to be adapted and adjusted to ensure the compatibility between the driver and the LED, and the practicability is poor.
