Abstract
An exemplary streetlight system for illuminating a road surface comprises an illuminating device, an infrared detection device and a controlling device. The illuminating device includes a light source. The infrared detection device is configured for detecting whether there are vehicles or passersby on the road surface and generating a detection signal. The controlling device is configured for receiving the detection signal, generating a controlling signal according to the detection signal and sending the controlling signal to the light source, thereby modulating the brightness of the light source.
Claims9
A streetlight system for illuminating a road surface, comprising:
- an illuminating device having a light source for selectively providing a lower illumination brightness or a higher illumination brightness;
- an infrared detection device configured for detecting a vehicle or a passerby on the road surface and generating a detection signal associated therewith;
- and
- a controlling device configured for controlling the light source to provide the higher illumination brightness according to the detection signal.
A streetlight system for illuminating a road, comprising:
- a light source for selectively operating at a first state where the light source provides a lower illumination brightness or at a second state where the light source provides a higher illumination brightness;
- an infrared detection device configured for detecting infrared emission of a passersby passing by the light source and generating a triggering signal associated therewith;
- and
- a controlling device configured for switching the light source to operate from the first state to the second state based on the triggering signal.
