[Prior Art] φ LED street light and related intelligent lighting system are the focus of technical research in recent years. Because existing LED lights have the advantages of digital control, such as lighting on/off control or brightness control, etc. Research on digital control of LED street lights set on the road. At present, the more mature LED lamp digital control technology is a DALI dimming system using a digital addressable lighting interface (DALI), which mainly includes a DALI main controller 51 and a plurality of DALI sub-controllers 52. When using, the complex DALI sub-controller 52 is respectively set on the control end of the LE D luminaire to be controlled; in the digital address dimming interface, the single DALI main controller 51 can simultaneously control 64 DALI sub-controllers at the same time. 52 'that can control 64 sets of LED luminaires at the same time, so DALI dimming system is widely used in many applications such as stage lights, such as stage lights, for different lighting performance control. Therefore, please refer to FIG. 5 'There is also a related research department directly using the above DALI dimming system for the control application of the LED street lamp; since each LED street lamp is provided with a digitally controllable power supply 53 , It can be directly connected to the DALI sub-controller 52 in the DALI dimming system, so that the M439317 multiple LED street lights can be individually controlled by the single DAL|master controller 51' and the user can control the dal dimming for the convenience of the user.

In addition, in order to further increase the transmission distance between the data concentrator 11 and the digital controllers 20, the present invention further integrates a repeater 12 between the two to enhance the strength of the power line communication signal. . Referring to FIG. 2, when the data concentrator uses the existing power line 200 as a transmission medium and outputs the dimming data data by using the power line communication signal as a carrier, the digital controller 2 can be configured by its pLC. The communication module 21 captures the dimming data through the existing power line 2, and controls the dimmer 30 accordingly, thereby adjusting the brightness of the |_ED street lamp; since the power line communication technology signal can be transmitted several kilometers away, Therefore, the effect of remotely controlling the LED street light can be effectively achieved.
