You can control exterior lighting with integrated timers and photocells. This is especially important for building managers and business owners, as it's the part of the facade lighting that promises the most savings. You wouldn't want to start with decorative lighting only to face high electricity bills. Therefore, after choosing the product with the correct wattage, you need to clarify this issue. In this article, we will discuss methods for making On/Off systems smart.
Automatic Control Methods in Facade Lighting
With On/Off lighting systems, you need to determine in advance when the lights will turn on and when they will turn off. This can be done with automatic control systems and automation, as manual switching is now an outdated and ineffective method. The three most commonly used systems are photocell systems, astronomical timers, and timer systems. Of course, whichever you choose, your electrician should select the most suitable contactor and relay set. Now let's talk about how these main options work.
Photocell Systems:
The sensor measures the natural light level in the environment. When the light falls below a predetermined threshold, the facade lights automatically turn on. When it rises above that threshold, they turn off. In short, this system turns on the facade lighting at sunset and turns it off at sunrise. It provides real-time control based on daylight. It adapts to seasonal changes. That is, it activates earlier in winter when the days are short, while it turns on later in the day during long summer days.
Astronomical Time Clock
Based on geographical location and date information, it calculates sunrise and sunset times. Based on this data, it automatically adjusts the lights to turn on and off. It is not affected by daylight fluctuations or cloudy weather. It automatically adjusts to sunrise and sunset times throughout the year. However, if you don't need the facade lighting to run all night, you should consider the timer option.
Time Clock
It turns on and off exactly at the times you specify. When using a digital time relay, you can easily enter the desired times from its menu. This allows for more precise and flexible control.
| Control Method | Working Principle | Its biggest advantage |
|---|---|---|
| Photoelectric Sensor | It measures the light intensity in the environment. | It reacts instantly to weather conditions (cloudy/dark). |
| Astronomical Time Clock | It uses location/coordinate data. | It requires no adjustment or maintenance during seasonal changes. |
| Standard Time Clock | Specified fixed time intervals. | It offers the option to shut down at midnight (e.g., 01:00). |
