While simple, it can lead to color shifts and is less efficient. Analog dimming reduces the current gradually. This can cause the LED to emit light at varying intensities and maybe change its color. This method also tends to dissipate more power as heat, reducing the overall efficiency of the system.<\/p>\n\n\n\n<p>\u2013 <strong>Phase-Cut Dimming<\/strong>: Used in AC-powered LED drivers, it chops the AC waveform to reduce power. It can introduce flicker and compatibility issues with some LED drivers. Phase-cut dimming works by cutting off a portion of the AC waveform, effectively reducing the average power delivered to the LED. This method can cause compatibility issues with some LED drivers. This leads to flicker and poor performance. It also requires more complex circuitry to implement, which can increase the cost and complexity of the lighting system.<\/p>\n\n\n\n<p>PWM dimming is more efficient. It also provides precise control and keeps color consistent. It is better in many applications. PWM dimming modulates power with a high-frequency signal. It avoids the issues of analog and phase-cut dimming. PWM dimming is a more reliable and flexible solution. Also, PWM dimming works with digital control systems. It enables advanced features such as programmable dimming profiles, remote control, and integration with smart home systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u062a\u0637\u0628\u064a\u0642\u0627\u062a \u0645\u062d\u0631\u0643\u0627\u062a \u0627\u0644\u062a\u0639\u062a\u064a\u0645 \u0628\u062a\u0642\u0646\u064a\u0629 PWM \u0627\u0644\u0645\u062a\u0648\u0641\u0631\u0629 \u0641\u064a \u0627\u0644\u0633\u0648\u0642<\/h2>\n\n\n\n<p>PWM dimming drivers are increasingly important in LED lighting. However, it is crucial to understand that there are two distinct methods for implementing PWM dimming drivers. Let&#8217;s explore these methods.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u062a\u0639\u062a\u064a\u0645 PWM \u0627\u0644\u0632\u0627\u0626\u0641<\/h3>\n\n\n\n<p>The fake PWM dimming method involves converting PWM inputs into an analog control signal. This method uses a resistor-capacitor (RC) filter within the driver. The RC filter smooths the PWM signal into a DC voltage proportional to the duty cycle. One advantage of fake PWM dimming is that it is noise-free since the LED current remains continuous at the output.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"284\" src=\"https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-5.png\" alt=\"\" class=\"wp-image-12675\" srcset=\"https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-5.png 900w, https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-5-300x95.png 300w, https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-5-768x242.png 768w, https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-5-18x6.png 18w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><figcaption class=\"wp-element-caption\">PWM Dimming description from Meanwell HLG series product datasheet<\/figcaption><\/figure>\n\n\n\n<p>However, this method has significant drawbacks. The peak value of the PWM signal must be 10V to ensure accuracy, which can be a limitation. Also, the RC parameters limit the PWM signal&#8217;s frequency. This reduces the dimming system&#8217;s flexibility and performance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u062a\u062e\u0641\u064a\u062a \u0627\u0644\u0625\u0636\u0627\u0621\u0629 \u0628\u0627\u0633\u062a\u062e\u062f\u0627\u0645 \u062a\u0642\u0646\u064a\u0629 PWM \u0627\u0644\u062d\u0642\u064a\u0642\u064a\u0629<\/h3>\n\n\n\n<p>In real PWM dimming, the LED currents switch on and off at the specified frequency and duty cycle. A microcontroller (MCU) inside the driver detects the peak voltages of the PWM signal, allowing for precise control. Real PWM dimming supports a broader range of PWM frequencies and preserves the white point of the LED output. It also accommodates a higher reference voltage, reducing offset errors.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"546\" src=\"https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-6.png\" alt=\"\" class=\"wp-image-12676\" srcset=\"https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-6.png 800w, https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-6-300x205.png 300w, https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-6-768x524.png 768w, https:\/\/boqiled.com\/wp-content\/uploads\/2024\/06\/image-6-18x12.png 18w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Programming Software interface<\/figcaption><\/figure>\n\n\n\n<p>All boqi drivers, for example, integrate an MCU to facilitate true PWM dimming.
