Information About Daylight Sensors
Daylight sensors are sensors that regulate the brightness of the environment by automatically changing the brightness of the lighting fixtures by measuring the equivalent lighting intensity created by the electric lighting fixtures together with the daylight in the environment that needs to be illuminated. The purpose of use of these sensors is to provide energy efficiency in indoor and outdoor lighting by utilizing sunlight. Sunlight is natural lighting and electric luminaires are artificial lighting. When used together, they provide comfortable lighting for people. Daylight saving increases visual comfort and helps you save energy and money on your lighting bills. It adjusts the brightness of the artificial light according to the ambient light in your space and maintains the desired light level.
Many indoor spaces, such as warehouses, factories, and parking garages, have windows that let in natural light. However, natural light alone may not be sufficient to provide adequate and correct lighting for human vision and safety. Artificial lighting is required to complement daylight, but using it at full brightness can result in over-lighting and waste of energy. The use of daylight sensors is a very important factor here. A daylight sensor is a device that measures the amount of natural light in a space and adjusts artificial lighting accordingly. Only by dimming or turning off electric lights when there is sufficient ambient light from daylight, daylight sensors can maintain a constant level of brightness. They can also increase people's comfort and productivity by providing a more balanced and dynamic lighting environment. Daylight sensors can also be used for outdoor applications such as street lighting or parking lot lighting.
A daylight sensor is a photocell device that converts light into an electrical signal. It is used to detect the presence or absence of sunlight and to measure the amount of sunlight in the space. It is very important to position the daylight sensors at the correct focal point. The system is turned on or off according to the daylight point to be adjusted. If the light level (lux) measured by the daylight sensor is less than the value, the illuminations are turned on, if it is higher, they turn off. A value of 100 lux for corridors, 150 lux for stairs, and 300-500 lux for offices is recommended. With the effect of weather changes (such as cloudy or sunny weather), daylight sensors can save between 20 and 60 percent of the electrical energy spent on lighting. Daylight saving not only saves energy consumption, but also improves the visual experience. Daylight saving also helps reduce operating costs, which are critical for both industrial and commercial facilities.
