How to solve the problem of LED dimming power supply
2023-11-10
Now we can find that the thyristor LED dimming power supply has penetrated into many fields, whether it is daily management, basic use and maintenance, there are corresponding problems. In the past two years, the market competitiveness of the industry has gradually increased, so that we can see that there are many management problems in the controller equipment. How can we effectively improve it?
Why is the same RGB light belt, the price gap is so big, what are the differences?
When buying RGB strips, you may find that even for the same type of product, the price difference is very different. Why is the same RGB light band, the price will have such a big gap? This article will reveal the secret, to help you better understand the reasons for the price difference of RGB light band.
Features and application of LED bathroom mirror!
LED bathroom mirrors are becoming more and more popular in modern home decoration. Its main features include energy saving, environmental protection, high brightness and long service life. LED lamps have the advantages of low energy consumption and high brightness, providing users with bright and uniform light, making daily activities such as makeup and shaving more convenient and faster. In addition, LED lamps also have a long service life, which can generally reach tens of thousands of hours, reducing the frequency of replacing bulbs and saving maintenance costs.
LED power supply according to the classification of driving mode
2024-03-16
The output current of the constant current drive circuit is constant, but the output DC voltage varies within a certain range with the size of the load resistance. If the load resistance is small, the output voltage will be low. The larger the load resistance, the higher the output voltage; The constant current circuit is not afraid of short circuit of the load, but it is strictly forbidden to open the load completely;
Introduction of LED Constant Current Driving Power Supply
Because the LED is a characteristic-sensitive semiconductor device and has a negative temperature characteristic, it needs to be stabilized and protected during the application process, resulting in the concept of driving. The requirements of LED devices on the driving power supply are almost harsh. Unlike ordinary incandescent bulbs, LEDs can be directly connected to 220V AC mains. LED is a 2~3 volt low voltage drive, it is necessary to design a complex conversion circuit, different uses of LED lights, to be equipped with different power adapters. On the international market, foreign customers have very high requirements for the efficiency conversion, effective power, constant current accuracy, power supply life and electromagnetic compatibility of LED drive power supply. To design a good power supply, we must consider these factors comprehensively, because the role of power supply in the whole lamp is as important as the human heart.
LED drive power supply design considerations
At present, LEDs are driven by DC, so a power adapter is required between the mains and the LED, that is, the LED drive power supply. Its function is to convert the AC mains into a suitable LED DC. According to the power grid rules and LED drive characteristics requirements, in the selection and design of LED drive power supply should take into account the following points:
