BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to lighting means for illuminating an interior space, and a method and system for operating such lighting means, and more particularly, to a lamp using a light emitting diode as a light emitting element and a method and system for controlling such a lamp.

Fluorescent lamps are most commonly used as lighting devices, but such fluorescent lamps consume more power than lighting efficiency, and use about 2.1 trillion kWh of electricity in annual power consumption. This amounts to 12-15% of the total electricity, generating 1.7 billion tons of CO2 annually.

In addition, the fluorescent lamp is not only manufactured using mercury, but also requires frequent replacement due to the short life of the lamp, and causes a serious environmental pollution problem in the case of the end of the fluorescent lamp.

Due to these problems, environmental regulations are tightening around the world, such as recently, some countries have banned the sale of fluorescent lamps.

Due to these problems, recently, lighting control systems have been constructed to individually control the luminaires, and furthermore, light-emitting diodes (LEDs) using energy-saving effects and eco-friendly LEDs are used as light emitting elements of the luminaires.

In the case of LED-based luminaires, there is little difference in price compared to fluorescent lamps, and it has excellent lifespan and energy savings as well as brightness.
