Abstract: An energy-saving street light system with dynamic real-time brightness adjustment includes a multiple of street lights, each storing a modulated brightness value of the same luminous quota and a predetermined brightness value. If the street light detects no motor vehicle passing by or receives no notice for a period of time, then a light with the predetermined brightness value will be emitted, or else the largest modulated brightness value will be used for setting and a quantity of one of the luminous quota will be used up. After the whole quantity of the luminous quota is used up, the next smaller modulated brightness value is used for the aforementioned setting procedure until all modulated brightness values are set. If the same receiving unit receives two or more modulated brightness values simultaneously, the modulated brightness value with a greater brightness will be used for the setting.

When the detection unit detects a human within the lamps sensor field of view one of the light emitting device, such light emitting device is defined as a primary lamp and all others are defined as secondary lamps. The primary lamp is adjusted to a maximum luminous intensity and the secondary lamps are adjusted outwardly from the primary lamp and decremented to a minimum luminous intensity. When any secondary lamp is near more primary lamps away from different distances, the one with a larger luminous intensity is used as a basis for adjusting the brightness after the luminous intensity of the secondary lamp is decremented. In the environment having the human-factor lighting system, the overall ambient luminous performance can be changed according to the moving position of people.
