The switch 90 is a mechanical push button switch in the home, and the switch 90 is used to turn on or off the current transmission path between the illumination device 1 and the power supply system 80, so that the supply current is input to the illumination device 1 when the switch 90 is turned on, to the illumination device. 1 Power supply. In one embodiment of the present invention, the lighting device 1 of the present invention includes a rectifying unit 10, a lighting unit 20, a battery 30, a detecting unit 40, and a control unit 50.

The rectifying unit 10 is electrically connected to the switch 90, The rectifying unit 10 is configured to convert the input supply current from an alternating current form to a direct current form.

The lighting unit 20 can illuminate when a supply current is passed or when the battery 30 supplies power thereto. In the specific embodiment of the present invention, the illumination unit 20 includes two light-emitting diodes, but the present invention is not limited thereto.

Battery 30 can be used to power lighting unit 20. In the specific embodiment of the present invention, the battery 30 is a lithium ion battery that can be used for repeated charge and discharge, but the present invention is not limited thereto.

In an embodiment of the present invention, the detecting unit 40 is electrically connected to the switch 90. The detecting unit 40 is configured to detect whether the switch 90 is turned on and whether the power supply current provided by the power supply system 80 is input to the lighting device 1, and generate a notification signal when detecting that the switch 90 is turned on and the power supply current is input. In the embodiment of the present invention, the detecting unit 40 is a Microcontroller Unit (MCU), but the creation is not limited thereto. Regarding the detection behavior of the detecting unit 40, the following will be described in more detail, and therefore will not be further described herein.

In an embodiment of the present invention, the control unit 50 is electrically connected to the rectifying unit 10, the lighting unit 20, the battery 30, and the detecting unit 40. The control unit 50 is configured to be used according to the notification signal generated by the detecting unit 40. In the case of having electric power, the control battery 30 supplies power to the lighting unit 20 to cause the lighting unit 20 to emit light. In the specific embodiment of the present invention, the control unit 50 is a Microcontroller Unit (MCU), but the present invention is not limited thereto. Regarding the control behavior of the control unit 50, the following will be described in more detail, and therefore will not be further described herein. It should be noted that the detection unit 40 and the control unit 50 of the present application are actually used. It can also be implemented in a single microcontroller.

Please refer to Figure 1 and Figure 2 together. FIG. 2 is a flow chart showing the steps of the first embodiment of the method for controlling the illumination of the light source during the power failure of the present invention. The steps shown in FIG. 2 will be sequentially described below with reference to FIG. It should be noted that, in the following, the illumination device 1 is taken as an example to describe the method for controlling the illumination of the light source during the power failure disclosed in the present invention, but the method is not limited to the illumination device 1 described above.

First, step 201 is performed to detect whether the switch is turned on.

First, in order to confirm the use state of the switch 90, in the present embodiment, the detecting unit 40 in the lighting device 1 of the present invention continuously sends a loop detection signal to judge whether the switch 90 is turned on or off. As shown in FIG. 1 , after the signal is sent, if the switch 90 is turned on, since the transmission path is in a closed loop state, the loop detection signal is transmitted back to the detecting unit 40 within a predetermined time; After the signal is sent, if the loop detection signal cannot be detected within the predetermined time, the switch 90 is turned off; therefore, the detecting unit 40 can generate a loop detection signal and issue a loop. After a predetermined time after detecting the signal, it is determined whether the switch 90 is in an on state according to whether a loop detection signal is received.

Then proceed to step 202: detecting whether the power supply current is input to the lighting device.

When the switch 90 is turned on, if the power supply system 80 can supply power normally, the power supply current generated by the power supply system 80 is input to the lighting device 1; and since the detecting unit 40 is connected in series with the switch 90, once the power supply current is input to the lighting device 1, detection The unit 40 can detect the supply current; on the contrary, the power supply system 80 fails to supply power normally, the supply current cannot be generated, and the detection unit 40 cannot detect the supply current input. Therefore, after the determination switch 90 is turned on, the detecting unit 40 can determine whether the power supply system 80 is normally powered by detecting whether the power supply current is input.

Go to step 203: Control the supply current through the lighting unit.

In the embodiment of the present invention, when the detecting unit 40 detects that the switch 90 is turned on and the power supply current is also input to the lighting device 1, the control unit 50 controls the power supply current through the lighting unit 20, even if the power supply system 80 supplies power to the illumination unit 20, so that the two light-emitting diodes in the illumination unit 20 can be illuminated by the supply current.

In addition, in the implementation of the present invention, when the switch 90 is turned on and the power supply current is input to the illumination device 1, if the battery 30 is in an uncharged state, the control unit 50 also controls a part of the supply current through the battery 30 to The battery 30 is charged by the supply current.

Go to step 204: Control the battery to supply power to the lighting unit.

When it is detected that the switch 90 is turned on, it means that the lighting device 1 is originally being used. Therefore, once the switch 90 is turned on and the detecting unit 40 fails to detect the power supply current input, the power supply system 80 is not When the power supply is normal, the detecting unit 40 generates and transmits a notification signal to the control unit 50; the control unit 50 controls the battery 30 to supply power to the lighting unit 20 according to the notification signal. In the embodiment of the present invention, in order to extend the power supply time of the battery 30, in step 204, the control unit 50 only controls the battery. 30 is configured to supply power to one of the illumination units 20 to cause the light-emitting diode to emit light by powering the battery 30; in detail, in the embodiment of the present invention, the illumination unit 20 is powered by a battery When the power is supplied from 30, the luminance of the light is less than the luminance of the light when the light is supplied by the supply current.

Step 205 is performed: the illumination unit is not illuminated.

In step 201, once it is detected that the switch 90 is not turned on, if the power supply system 80 is in a normal power supply state, the power supply current generated by the power supply system 80 may not be input to the lighting device 1 due to the non-conduction of the switch 90, that is, the power at this time. The supply system 80 cannot supply power to the lighting device 1 regardless of whether it is normally powered. When the switch 90 is not turned on, it means that the lighting device 1 is not used before, for example, it is daytime or the user goes out. Therefore, in order to save the power of the battery 30, once the switch 90 is not turned on, the control unit 50 does not control. The battery 30 supplies power to the illumination unit 20. At this time, the illumination unit 20 does not emit light when the supply current is not input and the battery 30 is not powered.

After the user wants to use the lighting device 1 and the power supply system 80 still fails to supply power normally, it only needs to press the switch 90 to turn on the switch 90, and then the lighting unit 20 can be further controlled by the above-mentioned judging mechanism. It is powered by the power supply of the battery 30 to achieve the function of emergency lighting during power failure.

Finally, please refer to Figure 1 and Figure 3. FIG. 3 is a flow chart showing the steps of the second embodiment of the method for controlling the illumination of the light source during the power failure of the present invention. The steps shown in FIG. 3 will be sequentially described below with reference to FIG. In the following, it should be noted that the following illuminating device 1 is taken as an example to illustrate the method for controlling the illumination of the light source during the power failure disclosed in the present application, but the method is not used in the foregoing. The lighting device 1 is limited.

First, step 301 is performed to detect whether the power supply current is input to the illumination device.

The difference from the foregoing embodiment is that, in this embodiment, the detecting unit 40 does not continuously generate the loop detection signal, but only generates the loop detection signal when the supply current input is not detected. In other words, once the detecting unit 40 detects that there is a supply current input, it means that the switch 90 must be turned on and the power supply system 80 is also normally powered, so no loop detection signal is issued at this time. Therefore, in the embodiment, the first step is to detect whether the power supply current is input to the illumination device, and once the supply current input is detected, the control unit 50 controls the supply current to pass through the illumination unit 20 to cause the illumination unit 20 to Light is emitted by the supply current (ie, step 302 is performed).

Further, in the present embodiment, when the supply current is input to the illumination device 1 and the battery 30 is not fully charged, the control unit 50 also controls a portion of the supply current to pass through the battery 30 to cause the battery 30 to be charged by the supply current.

Then proceed to step 303: detecting whether the switch is turned on.

As described above, when the detection unit 40 does not detect the supply current input, the detection unit 40 cannot detect the supply current because of two conditions, and therefore, the supply current is not detected. In the case of illuminating device 1, in order to further confirm that the supply current is not input, the detecting unit 40 will issue a loop detection signal at this time to judge whether the switch 90 is turned on or off. Since the method of detecting whether the switch 90 is turned on is the same as the method described in the foregoing embodiment, no further description is made here.

Go to step 304: Control the battery to supply power to the lighting unit.

In step 303, once it is detected that the switch 90 is turned on, it can be determined that the power supply current is not input because the power supply system 80 fails to supply power (ie, power failure), and the detecting unit 40 generates and transmits the data. A notification signal is sent to the control unit 50, and the control unit 50 controls the battery 30 to supply power to the lighting unit 20 according to the notification signal in a state where the battery 30 has power, so that the lighting unit 20 is not normally powered even when the power supply system 80 is not powered. It can also be illuminated by the power supplied by the battery 30 for emergency lighting. Similarly, in the present embodiment, the illumination unit 20 emits light by the battery 30 to emit light with a luminance that is less than that when the light is supplied by the supply current.

Go to step 305: Make the lighting unit not emit light.

Conversely, in step 303, upon detecting that the switch 90 is in a non-conducting state, it can be determined that the user is not using the lighting device 1, such as going out or during the daytime, and therefore, when the switch 90 is not conducting. In addition to the inability of the illumination unit 20 to illuminate the battery 30 of the illumination device 1 in addition to the illumination current, the control unit 50 does not control the battery 30 to supply power to the illumination unit 20.

Similarly, when the step 305 is completed, once the user wants to use the lighting device 1 and the power supply system 80 still fails to supply power normally, it only needs to press the switch 90 to turn on the switch 90, and then by the foregoing The judging mechanism causes the lighting unit 20 to emit light by the power supply of the battery 30 to achieve the function of emergency lighting during power failure.

It should be noted that during the power outage revealed by this creation The method of controlling the illumination of the light source is not limited to the order of the steps of the above embodiments, and the order of the above steps may be changed as long as the purpose of the present invention can be achieved.

As can be seen from the above description, the lighting device 1 of the present invention can be used as a general lighting device when the general power supply system 80 is normally powered, and can be used as an emergency lighting device when the power supply system 80 cannot supply power normally. Moreover, the lighting device 1 of the present invention can detect whether the switch 90 is turned on to determine whether the lighting device 1 is being used by the user, and further, according to whether the lighting device 1 is being used or not, controlling the lighting unit 20 to emit light or not during a power outage. The illumination is illuminated to suspend illumination of the illumination unit 20 in the event of a power outage, but without the need for emergency lighting, thereby saving unnecessary power consumption of the battery 30 of the illumination device 1.

In summary, this creation shows its characteristics different from conventional technology in terms of purpose, means and efficacy. It is to be noted that the various embodiments described above are merely illustrative for ease of explanation, and the scope of the claims is intended to be limited by the scope of the claims.
