The conventional street lights cannot turn on and off the lights according to the relationship between seasons, and the current street lights can only be turned on and off according to a fixed time, which makes the passers-by feel very inconvenient. Falling off early, but the street lights have not been turned on, will make it unsafe for passersby.

The street light device of the present invention can receive radio waves through the radio wave element, and transmit the information containing the standard time transmitted by the timing base station to the control element in the street light, so that the time in the street light is the same as the standard time.

Hereinafter, the present invention will be described in detail by illustrating various embodiments of the present invention by means of the drawings. The concepts of the invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

First, please refer to FIG. 1 , which is a flow chart of an embodiment of the present invention. As shown in the figure, its structure includes a street light 10 , a control element 20 and a radio wave element 30 .

Next, please refer to FIG. 2A, which is a schematic circuit diagram of an embodiment of the present invention, and FIG. 2B, which is a schematic diagram of information transmission according to an embodiment of the present invention. As shown in the figures, the device of the present invention is The system includes the street light 10, the control element 20 and the radio wave element 30. The street light 10 is electrically connected to a first power supply terminal 92 of an AC power source 90. The street light 10 is provided with a light pole 12, one end of the light pole 12 A light-emitting device 14 is provided, the control element 20 is electrically connected to the first power terminal 92 and a second power terminal 94 of the AC power source 90 , and a third power terminal 96 of the control element 20 is electrically connected to the light-emitting device 14, wherein, the control element 20 further includes a radio wave element 30, the radio wave element 30 has an antenna 32, the radio wave element 30 is electrically connected to a timing element 22 in the control element 20, the radio wave The element 30 receives a signal M from 30KHz to 300KHz through the antenna 32, the time control element 22 corrects a time according to the signal M, and displays the correct time on a time display unit 24. Further, the antenna 32 is a Copper, aluminum, liquid crystal polymer or modified polyimide, the control element 20 is built in the light emitting device 14 .

And the above-mentioned radio wave element 30 can receive the signal M without using a communication line or a wireless communication device, which is different from the conventional smart street light, although it can automatically adjust the time, but it needs to pass a common communication line (for example, a network line). ) or through a wireless communication device (such as a WIFI receiver) to receive external signals.

In addition, the light-emitting device 14 includes an LED light source 142 and an LED driver 144. The LED driver 144 is electrically connected to the first power supply terminal 92 and the control element 20 and supplies a DC power supply 98 to the LED light source 142. The control element 20 transmits a light source control signal 60 to the LED driver 144 . When the LED driver 144 receives it, it transmits a receive signal 70 to the control element 20 and controls the LED light source 142 according to the light source control signal 60 brightness.

Furthermore, the signal M is obtained by converting a radio signal (not shown) transmitted by a base station (a conventional radio wave transmitting station, so not shown), and the signal M includes a national standard time value.

Wherein, a remote control unit 40 is electrically connected to the base station, and switches the AC power source 90 according to the national standard time value to control the lighting device 14 to be turned on or off.
