Automatically shedding loads for lighting systems in corridors and public areas in high-rise apartment buildings

Currently, the lighting system for corridors and public areas in high-rise apartment buildings uses LED systems to replace Sodium lamps, halogen lamps... Although LED lights have been put into use, there are economic benefits such as lower power consumption and longer durability (life expectancy) according to the manufacturer's explanation. But in practice, the LEDs are used with pulse sources with operating voltages from 170VAC to 240VAC and continuous operation time without rest, often resulting in power loss due to overload or the life of the capacitor is reduced. Therefore, in order to improve the life span and efficiently use the energy source, the researches have studied the switching process control such as [1], [2], [3], [5].

This paper presents a new research direction Automatically shedding loads for lighting systems in corridors and public areas in high-rise apartment buildings for greater efficiency.
