The development trend of LED power supply driver - LED power supply driver is a voltage converter that converts the power supply into a specific voltage and current to drive LED lighting. In recent years, with the development of LED, the development trend of LED power drivers has become particularly evident. Today, I will briefly explain the development trend of LED power drivers to you. Firstly, a series of constant voltage and current control electronic circuits are developed based on the characteristics of LEDs. Integrated circuit technology is used to control the input current of each LED at the optimal current value, enabling the LED to obtain stable current and generate the highest output luminous flux. It is best to control the size of LED current when the input voltage and environmental temperature of the LED driver power supply change. (Related knowledge: Classification of LED backlight sources) Secondly, the LED driver power supply has intelligent control function, allo
1. Quality issues The quality of the fuse is very important. If the fuse installed in the circuit is of poor quality, it is easy for the fuse to malfunction after the circuit is connected and when the circuit is overloaded, resulting in the circuit being unusable or burned out. 2. Model not suitable If the fuse model is not suitable, two situations will occur: ① When the rated current of the fuse is too low, it will be installed in the circuit and connected to the power supply. If the fuse blows, the circuit cannot be powered on and the equipment cannot operate normally. ② When the circuit is overloaded, it will not be able to fuse in a timely manner, which will not only burn out the circuit, but also easily cause fires and other accidents 3. Aging, oxidation If the fuse is stored for too long or in an incorrect manner, it can lead to oxidation, aging, and unusable. When the fuse is oxidized, it can be seen that the packaging of the product has fallen off. 4. Poor contact I
1. Replace with a suitable fuse model Don't rush when a fuse malfunctions. Disconnect the circuit first, eliminate the problem, and then replace it with a new one. The quality and model of the new fuse must meet the specified range of the circuit. 2. Perform an overload test on the fuse Conducting overload testing on fuses can effectively detect the quality of the fuses and select appropriate fuse models. After being tested on the machine and found to be fine, they can be installed and used. Can the fuse still be used after the circuit is overloaded? Answer: Whether the fuse can still be used after the circuit is overloaded depends on the type of fuse you installed in the circuit. If a disposable fuse is used in the installation circuit and the fuse blows after the circuit is overloaded, a new fuse needs to be replaced. If a self restoring fuse is used, the fuse will automatically block excessive current in the event of overload. After troubleshooting, the fuse can automatical
There are many types of fuses, including classification by protection form, scope of use, volume, rated voltage, breaking capacity, and fusing speed. Below is an introduction to the classification by type, which can be divided into: current fuses: patch fuses, miniature fuses, plug-in fuses, and tubular fuses; Temperature fuse: RH square type, RP resistance type, RY metal case; Self recovery fuse: plug-in, laminated, patch. 1、 Current fuse Chip fuse. There are specifications such as 0805 and 1206, which use thin film technology to accurately control electrical characteristics. Due to its small size, it is an ideal choice for providing secondary protection for circuits in space limited applications, such as handheld portable electronic devices and various instruments and meters. Insert a fuse. Commonly seen in automotive applications, sometimes also known as fork bolt fuses Tubular fuse. This is very common, especially in various power supply applications such as switching powe
If the fuse can be removed from the circuit, it can be a visual fuse to determine whether it has burned out; The simplest method to determine whether a fuse is a continuity test is to blow other materials. Quickly test with a multimeter to determine if it is working properly, by hearing a beep and touching the wires together, or seeing a 0 ohm reading. After confirming that the circuit power is turned off, place the leads at both ends of the fuse. If you hear the same beep and the resistance reading of the multimeter is very low, then the fuse will not blow. If you don't hear the beep and the meter reading is OL, the fuse will blow. Take reasonable preventive measures to stay away from dangerous voltages. Supply the power circuit and switch to the multimeter voltage measurement mode. Ensure that DC circuits are selected for DC and AC circuits are selected for AC Connect the multimeter leads on both sides of the fuse. If the indicated voltage is small or even not, the fuse is intact
In order to enable a broader participation of low-voltage electrical appliance professionals in standardization work, to understand standardization policies and trends, the National Low-Voltage Electrical Appliance Standards Committee is organizing a series of events for the 2023 Annual Standardization Conference and Low-Voltage Electrical Appliance Technology Conference from September 24th to 26th in XIAN. In 2023, under the leadership of the higher authorities and the joint efforts of various committee members, the National Low-Voltage Electrical Appliance Standards Committee actively organized and carried out various standardization activities, achieving fruitful results: earnestly implementing the National Standardization Development Outline, in accordance with the new version of the "National Standard Management Measures," focusing on the construction of the new standard system for distribution and utilization of electrical equipment and systems, and emphasizing the research
