Description

  The present invention relates to a lighting fixture, and more particularly, to a lighting fixture that functions as an emergency lighting in the event of a power failure.

  In order to respond to the emergency lighting demand at the time of power outage, most of the indoors now have emergency lighting equipment attached to general lighting, so that it can be used as emergency lighting when a power failure occurs due to the occurrence of typhoon, earthquake or other events Has fulfilled the function.

  However, most of the current emergency lighting fixtures are externally attached to household lamps, so that the aesthetics of the wall surface have been lowered when hung on the wall surface, in addition to purchasing separately. And once a power outage occurs, emergency lighting fixtures will automatically turn on regardless of whether you are using the light in your home, so this type of lighting is available during the day of the power outage or when no family members are present. The model is not very intelligent because it wastes the power stored in the emergency lighting fixture.

  Therefore, in order to improve the above problems, it was necessary to devise a new lighting apparatus.

  Therefore, the main object of the present invention is to provide a lighting fixture that functions as an emergency lighting in the event of a power failure.

  In order to achieve the main object of the present invention, the luminaire with an emergency lighting function of the present invention can be electrically connected to a power supply system used for providing a feeding current through a switch.

  Hereinafter, in order to make the above and other objects, features, and advantages of the present invention clearer and easier to understand, specific embodiments of the present invention will be described with reference to the accompanying drawings.

  First, a description will be given with reference to the installation configuration diagram of the lighting fixture of the present invention in FIG.

  As shown in FIG. 1, the luminaire 1 of the present invention can be electrically connected to a power supply system 80 through a switch 90. In the embodiment of the present invention, the power supply system 80 includes a power generation system 81 and a power adapter 82. In this embodiment, the power generation system 81 is a power generation facility in a power plant. During normal power supply of the power generation system 81, the power generation system 81 can generate and output a high-voltage power supply current. The high voltage power supply current is transmitted to the power adapter 82 on the utility pole via the cable, and is provided to the lighting fixture 1 by forming a power supply current having a relatively low voltage by the power adapter 82 after the voltage drop. The switch 90 is a push button switch of a mechanical contact point of a house, and conducts or cuts off a current transmission path between the luminaire 1 and the power supply system 80, and a feeding current is input to the luminaire 1 when the switch 90 is on. Is used to supply power to the lighting fixture 1. In one embodiment of the present invention, the lighting fixture 1 of the present invention includes a rectifying unit 10, a lighting unit 20, a power storage unit 30, a detection unit 40, and a control unit 50.

  The rectification unit 10 is electrically connected to the switch 90, and is used to convert the input feeding current from an alternating form to a direct form.

  The lighting unit 20 can emit light when a feeding current passes or when power is supplied from the power storage unit 30. In a specific embodiment of the present invention, the lighting unit 20 includes two light emitting diodes. However, the present invention is not limited to this.

  The power storage unit 30 can be used to supply power to the lighting unit 20. In a specific embodiment of the present invention, the power storage unit 30 is a lithium ion power storage unit that can be used repeatedly after repeated charging and discharging, but the present invention is not limited to this.

  In one embodiment of the present invention, the detection unit 40 is electrically connected to the switch 90. The detection unit 40 detects whether or not the switch 90 is turned on and whether or not the power supply current supplied from the power supply system 80 is input to the lighting fixture 1, and the switch 90 is turned on and the power supply current is input. It is used to generate a notification signal when it is detected. In the embodiment of the present invention, the detection unit 40 is a microcontroller (MCU), but the present invention is not limited to this. The detection behavior of the detection unit 40 will be omitted here since it will be described in further detail below.

  In one embodiment of the present invention, the control unit 50 is electrically connected to the rectifying unit 10, the lighting unit 20, the power storage unit 30, and the detection unit 40, and based on a notification signal generated by the detection unit 40. The power storage unit 30 is used to cause the lighting unit 20 to emit light by controlling the power storage unit 30 and supplying power to the lighting unit 20 under a state where the power storage unit 30 has power. In a specific embodiment of the present invention, the control unit 50 is a microcontroller (MCU), but the present invention is not limited to this. The control behavior of the control unit 50 will be omitted here because it will be described in further detail below. Therefore, in particular, the detection unit 40 and the control unit 50 of the present invention can be realized by being integrated in a single microcontroller even when actually used.

  Next, a description will be given with reference to FIGS. FIG. 2 is a step flowchart of Embodiment 1 of the method for controlling light emission of a light source during a power failure according to the present invention. The steps shown in FIG. 2 will be described below in order based on FIG. However, although the method of controlling light source light emission at the time of a power failure disclosed in the present invention will be described by taking the following lighting fixture 1 as an example, this method is not necessarily used only for the lighting fixture 1.

  First, step 201 for detecting whether the switch is conductive is performed.

  First, in order to confirm the use state of the switch 90, in the present embodiment, the detection unit 40 in the lighting fixture 1 of the present invention determines whether the switch 90 is conductive or cut off by constantly generating a loop detection signal. . As shown in FIG. 1, when the switch 90 is turned on after the signal is generated, the transmission path at this time exhibits a closed loop state, and therefore the loop detection signal is returned to the detection unit 40 within a predetermined time. Can do. On the contrary, when the return of the loop detection signal cannot be detected within a predetermined time after the signal is generated, it indicates that the switch 90 is in the cut-off state. Therefore, the detection unit 40 can determine whether the switch 90 is in a conductive state depending on whether or not the loop detection signal is received within a predetermined time after the loop detection signal is issued.

  Next, step 202 is performed to detect whether or not a feeding current is input to the lighting fixture.

  When the power supply system 80 can normally supply power when the switch 90 is turned on, the power supply current generated from the power supply system 80 can be input to the lighting fixture 1. Since the detection unit 40 and the switch 90 are connected in series, once the feeding current is input to the lighting fixture 1, the detection unit 40 can detect the feeding current. Conversely, if the power supply system 80 cannot normally supply power and no power supply current can be generated, the detection unit 40 cannot detect the input of the power supply current. Therefore, after determining the continuity of the switch 90, the detection unit 40 can determine whether the power generation system 81 is normally supplying power through detection of the presence / absence of input of the supply current.

  Step 203 of controlling the feeding current and passing through the lighting unit is performed.

  In the embodiment of the present invention, when the detection unit 40 detects that the switch 90 is turned on and the feeding current is also input to the lighting fixture 1, the control unit 50 controls the feeding current to control the lighting unit 20. Pass through. That is, by supplying power to the lighting unit 20 from the power supply system 80, it is possible to cause both of the two light emitting diodes in the lighting unit 20 to emit light via the feeding current.

  In addition, in the embodiment of the present invention, when the switch 90 is turned on and the feeding current is input to the lighting fixture 1, when the power storage unit 30 is not fully charged, the control unit 50 is also one. The power storage unit 30 can be charged through the power supply current by controlling the power supply current of the unit and via the power storage unit 30.

  Step 204 is performed to control the control power storage unit to supply power to the lighting unit.

  When the continuity of the switch 90 is detected, the luminaire 1 is being used originally, so that the switch 90 is once turned on, and the detection unit 40 cannot detect the input of the feeding current, that is, from the power supply system 80. When power cannot be normally supplied, the detection unit 40 generates a notification signal and transmits it to the control unit 50. The control unit 50 can control the power storage unit 30 based on the notification signal and supply power to the lighting unit 20. In the embodiment of the present invention, in order to extend the power supply possible time of the power storage unit 30, the control unit 50 controls the power storage unit 30 to supply power to only one of the light emitting diodes in the lighting unit 20 in step 204. As a result, the light emitting diode can emit light through the power supply of the power storage unit 30. More specifically, in the embodiment of the present invention, the light emission luminance when the illumination unit 20 emits light by the power supply of the power storage unit 30 is lower than the light emission luminance when light is emitted by the supply current.

  Step 205 is performed so that the lighting unit does not emit light.

  In step 201, once the switch 90 is detected to be non-conductive, the power supply system 80 enters a normal power supply state, and the generated supply current cannot be input to the lighting fixture 1 because the switch 90 is non-conductive. That is, at this time, regardless of whether power is normally supplied from the power supply system 80, none can supply power to the luminaire 1. Further, when the switch 90 is non-conductive, it indicates that the luminaire 1 is not used from the beginning. For example, to save the power of the power storage unit 30 during a power outage during the day or when the user is out. Once the switch 90 is non-conductive, the control unit 50 does not control the power storage unit 30 to supply power to the lighting unit 20. At this time, no power supply current is input to the illumination unit 20, and the power storage unit 30 does not emit light without power supply.

  Thereafter, when the user tries to use the luminaire 1 and cannot normally supply power from the power supply system 80, the switch 90 is turned on only by pressing the switch 90, and the determination unit again causes the lighting unit 20 to be connected to the power storage unit. By emitting light by power supply from 30, it can fulfill the function as emergency lighting at the time of power failure.

  Finally, description will be made with reference to FIGS. FIG. 3 is a step flowchart of Embodiment 2 of the method for controlling light emission of a light source at the time of a power failure according to the present invention. The steps shown in FIG. 3 will be described below in order based on FIG. Similarly, a method for controlling light emission of a light source at the time of a power failure disclosed in the present invention will be described using the lighting fixture 1 as an example, but this method is not necessarily used only for the lighting fixture 1.

  First, step 301 is performed to detect whether or not a feeding current is input to the luminaire.

  The difference from the above embodiment is that, in the present embodiment, the detection unit 40 does not continuously issue a loop detection signal, and issues a loop detection signal only when the input of the feeding current is not detected. In other words, once the detection unit 40 detects that there is an input of a feeding current, it indicates that the switch 90 is always turned on and that the power supply system 80 is also normally fed. For this reason, no loop detection signal is issued at this time. Therefore, in the present embodiment, step 1 detects whether or not a feeding current is input to the lighting fixture, and if it is detected that there is a feeding current input, the control unit 50 controls the feeding current. By passing through the illumination unit 20, the illumination unit 20 is caused to emit light via the feeding current (that is, step 302 is executed).

  In addition, in this embodiment, when a feeding current is input to the lighting fixture 1 and the power storage unit 30 is not fully charged, the control unit 50 similarly controls a part of the feeding current to supply power. The power storage unit 30 can be charged with a feeding current through the storage unit 30.

  Next, step 303 for detecting whether or not the switch is conductive is performed.

  Following the above, when the detection unit 40 does not detect the input of the feed current, neither of the two states is detected when the feed current is input to the luminaire 1 because the detection unit 40 cannot detect the feed current. In order to further confirm the cause of the non-input of the feeding current, the detection unit 40 issues a loop detection signal at this time to determine whether the switch 90 is conductive or cut off. Since the method for detecting the presence or absence of conduction of the switch 90 is the same as the method described in the above embodiment, detailed description thereof is omitted here.

  Step 304 is performed to control the power storage unit to supply power to the lighting unit.

  In step 303, once it is detected that the switch 90 is conducting, it can be determined that the cause of the non-input of the feeding current is not normally fed from the power supply system 80 (that is, a power failure). At this time, the detection unit 40 generates a notification signal and transmits the notification signal to the control unit 50. The control unit 50 controls the power storage unit 30 based on the notification signal in a state where the power storage unit 30 has power. Power is supplied to the lighting unit 20. Accordingly, the lighting unit 20 can be used as emergency lighting by emitting light using the power supplied from the power storage unit 30 even when power is not normally supplied from the power supply system 80. Similarly, in the present embodiment, the light emission luminance when the illumination unit 20 emits light through the power supply of the power storage unit 30 is lower than the light emission luminance when light is emitted through the supply current.

  Step 305 is performed so that the lighting unit does not emit light.

  On the contrary, in step 303, when the non-conducting state of the switch 90 is once detected, it can be determined that the user is not using the lighting fixture 1 but is out, for example, during the day. Therefore, under the non-conducting state of the switch 90, the lighting unit 20 cannot emit light via the feeding current, and the control unit 50 at this time saves the power of the power storage unit 30 of the luminaire 1. The lighting unit 20 is not supplied with power by controlling 30.

  Similarly, after step 305 is completed, once the user tries to use the luminaire 1 and power cannot be normally supplied from the power supply system 80, the switch 90 is turned on only by pressing the switch 90 to make the determination means again. Thus, the lighting unit 20 emits light through power feeding from the power storage unit 30, so that it can function as emergency lighting during a power failure.

  The method for controlling light emission during power failure disclosed in the present invention is not limited to the order of steps in the above-described embodiment, but can only achieve the object of the present invention and change the order of the steps.

  As can be seen from the above description, the lighting device 1 of the present invention can be used as a general lighting device under a normal power supply state from the general power generation system 81, and when the power supply system 80 cannot normally supply power, Can be used as a lighting fixture. And the lighting fixture 1 of this invention detects whether the switch 90 is turned on, the lighting fixture 1 judges whether the user is used correctly, and also depends on whether the lighting fixture 1 is in use. By controlling the light emission or non-light emission of the lighting unit 20 at the time of a power failure and temporarily stopping the light emission of the lighting unit 20 in a state where there is a power failure but no emergency lighting is required, the power storage unit 30 of the lighting fixture 1 is unnecessary. Saving power consumption.

  Through the above detailed description, all the objects, means and effects of the present invention are completely different from the features of the prior art. However, the plurality of embodiments described above are merely to clarify the technical contents of the present invention, and should not be limited to such specific examples. The scope of rights claimed in the present invention is as follows: Based on what is stated in the scope of the utility model registration request.
