Violent disassembly of 10-18W LED driver power supply

　　In the actual operation process, you must pay attention to the connection distance of the LED light strip. Generally speaking, the maximum connection distance of the 3528 series LED light strip is 20 meters, and the maximum connection distance of the 5050 series LED light strip is 15 meters. 　　LED light strips are L

　 LED stroboscopic effect refers to two concepts. One is stroboscopic: that is, the depth of the fluctuation of the luminous flux of the electric light source. The greater the fluctuation depth, the greater the stroboscopic depth. The other is stroboscopic effect: that is, the negative effect of the stroboscopic effec

This article will introduce an LED that has small size, low cost, high PF and high TRIAC brightness adjustment performance. This design uses a single-stage power factor correction (PFC) inverter converter with primary-side constant power control. It implements primary-side constant power control in a single-stage inve

　　The English name of LED wall washer lamp is Ledwashwalllamp, also known as linear LED floodlight, etc. Because of its long strip shape, most of them are wall washers with aluminum shells, also known as LED aluminum strip lights and LED linear lights. They are mainly used for architectural decorative lighting and to

As a new light source, LED power supply and drive circuit are different from the electronic ballast of fluorescent lamps. The main function of LED drive circuit is to convert AC voltage into DC voltage and match the voltage and current of LED at the same time. With the straight-line decline of silicon integrated circu

　　LED street lights are low-voltage, high-current driving devices. The intensity of their light is determined by the current flowing through the LED. Excessive current will cause the LED to attenuate, and too weak current will affect the LED's luminous intensity. Therefore, the LED driver needs to provide a constant c

1 Schematic It is not difficult to see from the picture that the entire P2 port is connected to the LED, and the entire P2 port needs to be driven when writing code. 2 Code #include "reg52.h" //This file defines some special function registers of the microcontroller #include intrins.h //Because we need to use t

　 　1. Basic introduction and definition of LED 　　Traditional lighting can no longer meet the needs of today's green and environmentally friendly development, and high-tech lighting technology has emerged. LED light-emitting diodes are a new generation of lighting products that will replace traditional lighting and b
