I did some study with the circuit and the part list. Voltage regulation across the diode was not ok and thus current regulation is also not ok in the second circuit voltage regulation across the diode was good but current regulation was not good only in the third circuit where voltage and current across the diode were very good ..and remember that the ultimate goal of led driver board is to keep current constant in the led.. One more thing I forget to mention is why this board called a boost!! The reference design consists of the CL8800, six resistors and a bridge rectifier (a Fairchild device). Xianglong (Shenzhen) Electronic Technology Co., Ltd. Pengjiang District Zhuoxing Hardware Factory, Shenzhen Intech Electronic Technology Limited. The purpose of led driver board is to keep current constant in the led If current increase in a led beyond predetremind level as recommended by the manufacture the led will just fail Current can increase in a led if we operate the leds by forcing voltage higher than the needed forward voltage or by other factors Intellectual Property Protection 浙公网安备 33010002000092号 Q:Can we visit your factory9 A: We welcome you paying us a visit at any time. Circuit Board Driver Led Experienced Circuit Board Manufacturer High Heat Dissipation B… Alipay I am very fresh into electronics, please excuse my ignorance if I say something fundamentally wrong. Our products are widely applied in Telecom, Medical, Automotive and Consumer Electronics. These capacitors are connected line to line and are designed for high voltage AC circuits. - User Information Legal Enquiry Guide, © 1999-2020 Alibaba.com. A LED driver circuit is a circuit which can power on and light an LED> We will simply use a transistor and a few resistors to bring about a circuit which, with minimal current, can produce enough current to drive and light an LED. WTWH Media LLC and its licensors. We are identified as one of the leading names in the market engaged in providing a wide range of High Power LED Driver PCB to our valued clients. | Suppliers Guitar Amplifier noise when a DC adaptor used. The flex circuit board holding the LEDs also holds the ac/dc driver circuit. I had so many bad experience with the existing LED driver in the market, and I want to know why. In this circuit, we will drive an LED directly from 230V AC Mains Supply. Here is a 23V0V LED Driver Circuit. hi every body just download the acrticle in word it is free. I was looking the for a constant current LED driver circuit the other day so that I can understand the principle of LED driver. - | Retro Analog Audio VU Meter From Scratch! 3.Design and produce almost any pcb as your requirement. Using one is very important in preventing damage to your LEDs as the forward voltage (V f) of a high-power LED … OPA Based Alice Microphones: a Cardioid and a Figure 8, DIY Raspberry Pi Desktop Case With Stats Display. Did you make this project? 2.Over 9 years experience in pcb manufacturing. Terms of Use | How to calculate amplification of a cone. EastwinPCBA Provides you the best range of High Power LED Driver PCB with effective & timely delivery. It is called so because it output voltage much much higher than its input voltage and can easily take in 30 to 50vdc and put out some thing in the range of 100 to 170vdc to drive a very large string of leds, This report is part of electronics repair course contact me if you want to buy the ebook kingwaeel@yahoo.com the price of the ebook is just 15usd !!
