· It takes additional components to make the LED driver dimmable and improve the power factor. This inevitably adds to the size and cost, but there are ways to minimize these penalties. To increase the power factor, the dc bus capacitor can be reduced so a large component of ripple will be present at twice the line frequency. Flicker is a common problem in LED industry. Many users complain that the LED lighting is always flickering, which is uncomfortable and bad for eyes. With the high development of technology, Triac LED dimmable driver cooperates with Triac dimmer can make it perfectly. Nowadays, LED is widely used. · Can I Make an Existing Fixture Dimmable? Probably. With the growth of LED technologies in recent years, most LED fixtures are dimming compatible. Once confirming with the manufacturer that your LED fixture can work with a dimming function, making the switch is as easy as just switching out the driver.
On the AC (input) side, you’ll connect the neutral and ground wires directly to the power source. The live wire from your household power source will connect to the input of the dimmer switch - and the output of the dimmer switch will then connect to the live wire of the dimmable driver. NOTE: Review the materials included with your dimmer switch and dimmable driver, as many installations will also require connecting the dimmer switch to ground. Connections can be made with wire nuts. LED driver and work by ‘chopping’ the AC input. For these types of dimmers, a LED driver that has ‘AC Phase Cut’ dimming is required. The may also be referred to as a ‘TRIAC dimmable LED driver’. The basic LED driver switching power supply circuit is not triac dimmable without some additional circuitry. Four techniques can be used to enable triac dimmer compatibility: a bleeder circuit, a charge pump, a simple PWM supply, and a complex PWM supply.
Dimmable LED Panel: When I saw the LED contest it got me thinking on if there was anything that would be fun to make that used LED's. I'm not really an electrical guy so I thought it would be a fun challenge. I had been looking at getting. Universal High-Power LED Driver - Firmware Update: Here's the updated firmware for my Universal High-Power LED Driver. This version has on-board current set up function, so you can change the drive current without re-programming the PIC. Arduino and MC LED Display Driver: As an increasing number of people enjoy experimenting with retro-hardware and electronics – especially stuff with numerical LED displays – they have discovered the classic MC LED display driver.T.
