With the continuous development of the times, lighting has gone through many stages, from ancient candles to breakthrough light bulbs, to incandescent lamps, LED lights, it can be said that lighting technology is constantly improving. Nowadays, LED has become the first choice for lighting in all walks of life, but pure LED lighting has also been unable to meet the requirements of various industries. In this context, smart lighting came into being.
China is a country with a shortage of resources, but in daily life, people are not aware of this. Efficient lighting technology has received widespread attention. LEDs are increasingly used in various lighting applications due to their high efficiency, low power consumption, low voltage drive, and long service life. They will completely replace traditional incandescent and fluorescent lighting in the foreseeable future. The lighting industry has brought about revolutionary changes.
Taking education lighting as an example, manual switches are used in many schools, and there is often a phenomenon that lights are not turned off in time, resulting in the waste of energy and shortening the service life of the lamps. In view of the waste of resources, it is necessary to study a smart lighting system to contribute to saving energy.
With the development of LED luminaires, the exploration of its functions is also in full swing. There is a significant difference between LED lamps and incandescent lamps. The luminance of LED lamps is basically proportional to the magnitude of the forward current flowing through the LED lamps.
Using this feature, the ambient brightness of the classroom is measured by the light sensor, and the brightness of the LED is changed according to the measured value, thereby maintaining the brightness of the classroom environment at a certain level, and constructing a learning place for the students to have a good mood. This not only creates a learning environment with constant brightness but also makes full use of natural lighting and saves energy.
