1 is a schematic view showing one of the first embodiments of the energy-saving light control substrate 1 of the present invention. Referring to FIG. 1 , the energy-saving lighting control board 1 is suitable for being installed in the lamp holder 62 of the lighting fixture 60. The energy-saving lighting control board 1 includes: a mains receiving end 101, a mains output end 102, a lighting switch 20, and a detecting The measuring module 30, the control module 10, the timing module 40 and the long lighting group 50 are connected between the lighting switch 20, the detecting module 30, the timing module 40 and the long lighting group 50. The detection module 30 is connected to the wall switch 70.

The mains receiving end 101 is connected to the mains 2 for receiving the mains power, and the mains output 102 is for outputting the mains power to the lighting unit 61 of the lighting fixture 60.

The light switch 20 includes an input end 21, a control end 22 and an output end 23, and the input end 21 is connected to the mains receiving end to receive the mains power. The control terminal 22 is connected between the input terminal 21, the output terminal 23 and the control module 10. The output terminal 23 is connected to the mains output 102, that is, the output 23 is electrically connected to the lighting unit 61 of the lighting fixture 60 via the mains output.

2 is a detailed architectural diagram of an embodiment of the light switch 20 of the present invention. Referring to FIG. 2, the control terminal 22 is controlled by the control module 10 to make the input terminal 21 and the output terminal 23 in an on state or an open state, that is, when the control terminal 22 is located above the figure, The input end 21 and the output end 23 are in an open state. Conversely, when the electrode plate connected to the control end 22 is located below, and the two ends of the electrode plate are respectively connected to the input end 21 and the output end 23 (Fig. Not shown), thereby forming an on state between the input terminal 21 and the output terminal 23. In some embodiments, the light switch 20 can be implemented by a relay, and the control terminal 22 receives the control signal of the control module 10 to energize the coil of the relay, and the attracting electrode plate is separated between the input end 21 and the output end 23, thereby The input terminal 21 and the output terminal 23 are in an open state. On the other hand, if the control terminal 22 does not receive the control signal, the electrode plate no longer receives the coil attractive force and is electrically connected between the input terminal 21 and the output terminal 23, so that the input terminal 21 and the output terminal 23 are in a conducting state. .

The detection module 30 detects a change in state between the on-state switch 70 and the off state. When the wall switch 70 is switched from the on state to the off state (as shown in FIG. 1 ), the detection module 30 detects a state change of the wall switch 70 , and the detection module 30 further transmits the state change. To the control module 10. Conversely, when the wall switch 70 is switched from the off state to the on state (not shown), the detection module 30 further transmits the state change generated by the wall switch 70 to the control module 10.

Therefore, the control module 10 receives the state change of the wall switch 70 via the detection module 30, thereby generating a control signal to the control terminal 22 of the light switch 20, and the control terminal 22 controls the input terminal 21 in response to the control signal. The output terminal 23 is switched to be turned on or open to further control whether the lighting unit 61 of the lighting fixture 60 receives the mains power, and the lighting unit 61 is turned on or off corresponding to the reception of the mains power. For example, when the control module 10 receives the state change of the wall switch 70, the control module 10 generates a control signal to the control terminal 22, and the control terminal 22 changes the input state 21 and the output terminal 23 from the current state. It is another state (such as changing from an on state to an open state, or from an open state to an on state). If the input terminal 21 and the output terminal 23 are changed from the open state to the conductive state, the illumination unit 61 can receive the mains power via the output terminal 23 to turn on the illumination; otherwise, if the input terminal 21 and the output terminal 23 When the conduction state is changed to the open state, the illumination unit 61 cannot receive the commercial power, and therefore the illumination unit 61 is in the off state.

When the illumination unit 61 is illuminated, the timing module 40 starts to count the lighting time and outputs a closed signal to the control module 10 when the lighting time arrives. The control module 10 causes an open circuit between the input end 21 and the output end 23 of the light switch 20 according to the closed signal output control signal, so that the lighting unit 61 of the lighting fixture 60 cannot receive the mains power, thereby the lighting fixture 60. The lighting unit 61 is switched to a state in which the illumination is turned off after the illumination is turned on to maintain the aforementioned lighting time.

When the timing module 40 outputs a closed signal to the control module 10 when the lighting time arrives, the wall switch 70 maintains the on state, that is, the closed state, and then, when the user operates the wall switch 70. When the state is changed from the on state to the off state (ie, in the open state), at this time, the control module 10 receives the state change of the wall switch 70, and sends a control signal to turn the light switch 20 from the off state to the on state. The state, and then the timing module 40 outputs a closed signal when the lighting time arrives to further turn the light switch 20 into an open state. At the same time, the wall switch 70 still maintains the open state, waiting for the next time. The lighting unit 61 of the lighting fixture 60 is turned on again by a state change by the user's operation. That is, even if the wall switch 70 is in the ON state, if the wall switch 70 is triggered when the illumination unit 61 is in the off illumination state, the wall switch 70 is turned to the OFF state, and the illumination can be turned on. Illumination of unit 61. Therefore, the energy-saving light control substrate 1 of the present invention is not affected by the on state or the open state of the wall switch 70, thereby being convenient for the user to operate, and can be easily installed in the original lighting fixture 60 without replacement Any component.

The long lighting group 50 is controlled by the control module 10 to be continuously illuminated during the period when the lighting unit 61 of the lighting fixture 60 is turned off, and is turned off during the lighting of the lighting unit 61 of the lighting fixture 60. In one embodiment, the long lighting group 50 is disposed at the lighting fixture 60. The present invention is not limited thereto. The long lighting group 50 may also be disposed at a distance near the lighting fixture 60 or the long lighting group 50. It is disposed on the energy-saving light control substrate 1. Thereby, during the closing of the lighting fixture 60, the long lighting group 50 can provide basic illumination of the common area to avoid the public area being too dim during the closing of the lighting fixture 60 to be dangerous.

The illumination of the long lighting group 50 is smaller than the illumination of the illumination unit 61 of the lighting fixture 60, that is, the lumen of the long lighting group 50 is smaller than the lumen of the lighting unit 61. Thereby, even if the lighting time of the long lighting group 50 is much longer than the lighting time of the lighting unit 61 of the lighting fixture 60, excessive energy waste is not caused.

The illuminant of the long-lighting group 50 can be composed of a power-saving LED lamp, a luminescent material, a power-saving bulb or other power-saving illuminators, and the invention is not limited thereto.

3 is a schematic structural view of a second embodiment of the energy-saving light control substrate 1 of the present invention. Fig. 4 is a schematic view showing the use of a second embodiment of the energy-saving light control substrate 1 of the present invention. Referring to FIGS. 3 and 4, the difference from the foregoing embodiment is that the wall switch 70 is two switch switches 701, 702, and the switch switches 701, 702 are respectively disposed at different positions. Here, as an example, when the user operates the switch 702, the common contact of the switch 702 is electrically connected to the electrical contact above the electrical contact (as shown in FIG. 3 to FIG. 4). As shown, the detection module 30 can detect the state change of the switch 702 to further enable the control module 10 to generate a control signal to cause the input terminal 21 and the output terminal 23 of the light switch 20 to be in an on state. The lighting unit 61 of the lighting fixture 60 is turned on to generate illumination. At the same time that the control module 10 generates the control signal, the timing module 40 starts to illuminate the lighting time. When the lighting time is reached, the timing module 40 sends a closed communication. The control module 10 drives the control module 10 to output a control signal to cause an open circuit between the input end 21 and the output end 23 of the lighting switch 20 to further prevent the lighting unit 61 of the lighting fixture 60 from receiving the mains power. Turn off the lighting. If the user operates the switch 701, the same function can be achieved, and details are not described herein.

Each of the changeover switches 701 and 702 is respectively disposed on a different floor, or a difference in the head and tail of the corridor, or the like in the other common areas, and the present invention is not limited thereto.

In this embodiment, only the two switches 701 and 702 are used for description. In other embodiments, three switches or a plurality of switches can be used, that is, the detecting module 20 detects three or The state of the switch of the three or more switches is changed to further detect the state change of each switch through the detecting module 30 to turn on the lighting unit 61 of the lighting fixture 60, and then turn off the lighting of the lighting fixture 60 according to the timing module 40. Illumination of unit 61.

According to the foregoing first and second embodiments, in an implementation aspect, the detection module 30 can also detect that the state change of the switch 70 on the wall is a single change or a continuous change, thereby making a single change or continuous The change causes the control module 10 to drive the timing module 40 into a short-time on mode or a long-time on mode. For example, when the detecting module 30 detects that the state change of the switch 70 on the wall changes to a single change, the control module 10 drives the timing module 40 to enter the short-time open mode, that is, the time length of the lighting time is equal to short. The length of time when the mode is on. When the detecting module 30 detects that the state change of the switch 70 on the wall changes continuously, the control module 10 drives the timing module 40 to enter the long-time open mode, so that the time of the lighting time is equal to the long-time opening. The length of time of the pattern.

When the lighting time of the short-time opening mode is long, the lighting time of the opening mode is short. For example, when the lighting time of the short-time opening mode is 5 minutes, the lighting time of the long-time opening mode may be 10 minutes. Or a longer length of time, but the invention is not limited thereto.

The lighting time of the short-time opening mode may be 5 minutes, 10 minutes, 15 minutes or other lengths of time, and the lighting time of the long-time opening mode may be 1 hour, 2 hours or other lengths of time, but the present invention does not This is a limitation.

The timing module 40 includes a preset time. The control module 10 generates an extension signal according to a state change of the wall switch 70 in a preset time, and the timing module 40 extends the lighting time according to the extension signal. In other words, after the control module 10 receives the state change of the wall switch 70 from the detection module 30, it will drive the timing module 40 to start the preset time, and if it is received on the wall in the preset time. When the other state of the switch 70 changes, the control module 10 will drive the timing module 40 to extend its lighting time. On the other hand, if another state change is not received in the preset time, the timing module 40 sends a power-off signal to the control module 10 according to the arrival of the original lighting time.

Therefore, when the detecting module 30 detects that the state change of the switch 70 on the wall changes to a single change, that is, another state change is not received in the preset time, the short-time open mode is maintained. On the other hand, if the detecting module 30 detects that the state change of the switch 70 on the wall changes continuously, that is, the first state change in the continuous change can drive the timing module 40 to start the preset time, and preset Receiving a second state change during the time, and thus cycling to satisfy the switch 70 on the wall for a predetermined number of times, causes the timing module 40 to enter the long-time on mode. However, the embodiment of the present invention is not limited thereto, and may enter the long-time on mode when a single change, and enter the short-time on mode when continuously changing.

In one embodiment, the lighting time of the timing module 40 is continued after the preset time, that is, after the control module 10 receives the state change of the wall switch 70, the chronograph module 40 starts the timing preset. Time, and then count the lighting time after the preset time is over. The length of the preset time may be 0.5 seconds, 1 second, 5 seconds, or other lengths of time, and the present invention is not limited thereto.

In some embodiments, when the detecting module 30 detects that a change occurs in the wall switch 70 during the lighting time, the control module 10 turns the input terminal 21 and the output terminal 23 from the conductive state to the open state. The state further changes the lighting unit 61 of the lighting fixture 60 from the lighting state to the off state, and the control module 10 also drives the timing module 40 to stop the lighting time.

Fig. 5 is a schematic view showing the architecture of a third embodiment of the energy-saving light control substrate 1 of the present invention. In one embodiment, the energy-saving lighting control substrate 1 further includes a setting module 11 , and the setting module 11 is electrically connected to the control module 10 . The setting module 11 has a plurality of setting states, each setting state corresponding to a different time length of the lighting time, and the control module 10 sets the time length of the lighting time of the timing module 40 according to the current setting state of the setting module 11. For example, the user can select one of the setting states through the setting module 11, so that the lighting time of the timing module 40 is 30 minutes, or the user can select another setting state through the setting module 11 to make The lighting time of the timing module 40 is 10 minutes, thereby allowing the user to select the length of the lighting time and more in line with the needs of the site.

The setting module 11 can be a dip switch, a multi-segment switch, a knob, and the like. The control module 10 has a storage space for storing a comparison table, and the comparison table records the length of time of the lighting time corresponding to each of the plurality of setting states of the setting module 11. Therefore, the user can adjust the setting of the time length of the lighting time of the timing module 40 by selecting the setting state of the setting module 11.

In an embodiment, the energy-saving lighting control substrate 1 further includes a state receiving module 12, and the electrical connection control module 10 and the security host 121. The state receiving module 12 receives the security state of the security host 121, and correspondingly generates The control module 10 receives and generates a control signal according to the security status signal, thereby further driving off the light switch 20, the detection module 30, the timing module 40, the long lighting group 50, or a combination thereof. run. The present invention is not limited by this example. If the security host 121 is turned on, it can indicate that no one can enter or leave any public area during the security-on period, so the security status signal is transmitted to the control module. After 10, the control module 10 can further generate a control signal for turning off the lighting switch 20, the detecting module 30, the timing module 40, the long lighting group 50 or a combination thereof, that is, during the security opening period, the operation can be turned off. To save power consumption.
