Taiwan's Feihong Technology's Japanese legal entity, Feihong Technology Japan, exhibited a wirelessly controlled dimming LED lighting power system at "LED Solutions 2011" (October 26-28, 2011, at the Pacific Yokohama Convention and Exhibition Center) .
The system uses an AC-DC conversion power supply circuit and a wireless communication module in combination. The wireless communication module uses a wireless LAN or "autonomous standard wireless" (using the 2.4 GHz band) communication method. The company used a power system embedded in its own standard wireless communication module in the exhibition area to demonstrate the opening, closing and dimming of straight tube LED lights. Currently selling to Japanese companies.
The self-standard wireless communication module has a transmission frequency of 2.4G to 2.383GHz. The data transmission speed is 50bit/sec (using FSK or GFSK) and the transmission distance is 16m. The PWM frequency for dimming is 1 kHz ± 50 Hz. With the control of this module, there are 5th order dimming (25% order), 9th order dimming (12.5% ​​order) and 5~100% 128 order dimming. It is said that a single remote control can be used to control multiple LED lighting fixtures. For example, a remote control can be used to control the ceiling lights on the same floor, the inside ceiling lights, and the lighting at the warehouse and office entrances.
The power system can support four powers: 15W, 30W, 55W, and 110W. The time to market is that the 55W power system is scheduled to be available in 2011, and 15W products and 30W products are scheduled to be available in January 2012. 110W products are under development.
To use the 1.25mm Ribbon Connector, you will need to first ensure that the ribbon cable is properly aligned with the connector. The pins on the connector should be lined up with the corresponding holes on the ribbon cable. Once the cable is properly aligned, you can then insert the connector into the corresponding socket on the device.
Overall, the 1.25mm Ribbon Connector is a reliable and versatile connector that is widely used in the electronics industry. Its high-density design and compatibility with ribbon cables make it an ideal choice for many applications
