Description

Energy-saving LED lighting using commercial power and DALI {ENERGY-SAVING LED LIGHTINGG USING COMMERCIAL POWER AND DIGITAL ADDRESABLE LIGHTING INTERFACE}

The present invention relates to LED lighting, and specifically to energy-saving LED lighting using commercial power and DALI.

AC commercial power is mainly used for lighting power.

However, AC commercial power has a disadvantage in that it consumes a lot of standby power when the lights are not turned on. Additionally, in the event of a power outage of AC commercial power, there is no way to turn on the lights at all unless a separate auxiliary generator is provided.

Meanwhile, when controlling numerous lights in a large building, there are cases where control is performed using the DALI (Digital Addressable Light Interface) protocol. The DALI lighting system has a dual structure in which it is controlled using the power of the DALI supply and uses the power of the ballaster as LED power.

It is not possible to control existing AC commercial power using the DALI protocol.
