International. Independent occupancy detectors and sensors are the first products that the company Havells Sylvania presented to the world market as part of its new line of business based on lighting control.
Sam Woodward, director of this segment at the company, said: "Companies currently have three fundamental challenges that are answered by controls: reducing carbon emissions, saving costs and compliance with legislation. Installing presence and light sensors could help reduce energy costs by up to 60%."
The official explained that there were two reasons why they decided to enter the lighting control segment. First because they consider it to be a natural development of the lighting business; second because the global trend is that in the coming countries each of the countries modify their regulations on lighting, benefiting the market for these products.
PIR sensors can operate in two ways: with the presence of detection the lights automatically turn on when a person enters a room and will automatically turn off after a predefined time interval when no movement is detected. On the other hand, with absence detection, the lights must be manually activated but it turns off automatically, which is perfect for classroom environments.
According to the company, the problems of false-firing sensors and exit lights when a room is still in use have been addressed by the two independently adjustable sensitivity levels : a sensitivity setting of a room in which occupancy has been detected, and another scenario of unoccupied rooms.
