100W Integrated Solar Street Light

How does the light know when to turn on and turn off?

Lights have various mechanisms by which they can turn on and off. Here are a few common methods:

Manual Control: Lights can be controlled with switches or buttons that are manually operated by people. These switches or buttons physically connect or disconnect the electrical circuit, turning the light on or off.

Motion Sensors: Lights fitted with motion sensors use infrared or ultrasonic technology to detect movement or changes in the surrounding environment. When the sensors detect movement, they activate the light to turn on. If no movement is detected within a specific time, the light automatically turns off.

Photocells: Some lights are equipped with photocells, also known as light-sensitive sensors. These sensors detect the ambient light level and automatically turn the light on when it gets dark and off when it gets bright. This is commonly used in outdoor lighting, streetlights, and security lights.

Timers: Lights can be connected to timers that allow them to be programmed to turn on and off at specific times. This is useful for scheduling lighting in spaces where consistent lighting patterns are required, such as commercial buildings or outdoor display lighting.

Voice or App Control: With the advent of smart home technology, lights can be controlled through voice commands or smartphone apps. Lights are connected to a central hub or Wi-Fi system, allowing users to turn lights on or off remotely or via voice commands using devices like Amazon Alexa or Google Assistant.In summary, lights can be controlled manually, sensed by motion or light-sensitive sensors, programmed with timers, or controlled through smart home technology.
