Description

  The present invention relates to an indoor lighting device used at home, and more particularly to an emergency LED (Light Emitting Diode) lighting device that supplements lighting with a storage battery as emergency lighting when a power failure occurs.

  As a conventional illumination device used in this kind of general home, an incandescent bulb, a halogen bulb, or the like is often used as an illumination light source. In recent years, with the development of science and technology, LEDs (Light Emitting Diodes) are being switched from light sources such as incandescent bulbs and halogen bulbs. This is because the use of LEDs provides advantages such as long life, energy saving, and environmental protection compared to conventional light sources.

  However, when considering from the viewpoint of emergency lighting, even when the conventional light source is switched to the LED, if a power failure occurs, it is necessary to provide a separate portable lighting device, and the above countermeasures have been taken. There is a problem that it is difficult to evacuate when there is a problem such as lack of lighting or losing sight of the location of the portable lighting device when considering an emergency that requires evacuation at night power outage .

  Therefore, in Patent Document 1, an AC power source and a secondary battery are provided as power sources for supplying power to the lighting device, and when the power supply from the AC power source is cut off during a power failure, the occurrence of a power failure is determined by a power failure detection circuit. The technology which secures the illumination at the time of a power failure by switching to the power supply from the secondary battery is disclosed.

  FIG. 3 is a block diagram showing a configuration example of a main part of a conventional emergency lighting system disclosed in Patent Document 1. As shown in FIG.

  As shown in FIG. 3, a conventional emergency lighting system 100 includes a power supply device 102 connected to an AC power supply 101 composed of a commercial power supply, and a plurality of units (here, light sources are turned on by power supply from the power supply device 102). 2) lighting fixtures 103A and 103B. The plurality of lighting fixtures 103 </ b> A and 103 </ b> B are connected in series between the output ends of the power supply device 102. Here, each of the lighting fixtures 103A and 103B constitutes a light guide plate type guide lamp as shown in FIG.

  The power supply apparatus 102 includes a power supply circuit 105 that converts the output of the AC power supply 101 into a predetermined DC voltage, a constant current circuit 106 that receives the output voltage of the power supply circuit 105 and outputs a constant DC current, and an AC power supply 101. In the energized state (hereinafter referred to as steady state), the switch element 107 connected to the output of the constant current circuit 106 is turned on. In the power failure state (hereinafter referred to as emergency), the switch element 107 is turned on. And a power failure detection circuit 104 which is controlled to be turned off.

  However, the power supply circuit 105 and the constant current circuit 106 may be combined into a constant current circuit. In addition, the power failure detection circuit 104 detects a power failure state when the output voltage of the AC power supply 101 falls below the first specified value in a steady state, while the output voltage of the AC power supply 101 reaches the second specified value in an emergency. If it exceeds, the energized state (power recovery) is detected.

  Here, the first and second specified values are set within the range specified for the guide lamp fixture in JIL (Japan Lighting Manufacturers Association Standard), and at least the second specified value is the first specified value. It is set larger than the value. The constant current circuit 106 may be configured to output a so-called pulse current in which a direct current is turned on / off at a low frequency of about several tens to several hundreds Hz.

  Each of the lighting fixtures 103A and 103B includes a light emitting diode (LED) 108 as a light source, a secondary battery 109 as an emergency power source, first to third switch elements 111, 112, and 113, and each switch element 111, 112 and 113 are controlled, and it has the switch control part 110 which comprises a switching means with the switch elements 111, 112 and 113, and the current limiting circuit 114, respectively.

  Each of the first to third switch elements 111, 112, and 113 is a single-pole bipolar device that alternatively connects a common contact to a contact (indicated by a in the figure) and b contact (indicated by b in the figure). It consists of a throwing type switch, and the a contact side is turned on when a current is supplied to the switch control unit 110. The high-potential-side power input terminals of the respective lighting fixtures 103A and 103B are connected to the common contact of the first switch element via each switch control unit 110, and the low-potential-side power input terminals are connected to the third power supply terminals. Is connected to contact a of the switch.

  Here, each of the lighting fixtures 103A and 103B has a light emitting diode 108 between the first switch element 111 and the second switch element 112 so that the a contact side of the first switch element 111 serves as an anode. Are connected in series, and between the common contacts of the second switch element 112 and the third switch element 113, the secondary battery 109 has a common contact side of the second switch element 112 as a positive electrode. And a current-limiting circuit 114 is connected between the contact a of the first switch element 111 and the contact b of the second switch element 112. Further, the b contact of the first switch element 111 and the a contact of the third switch element 113 are connected to each other, and the a contact of the second switch 112 and the b contact of the third switch element 113 are connected to each other. ing.

  With the above configuration, in the steady state when the AC power supply 101 is in an energized state, a predetermined current is output from the power supply device 102, and the first to third switch elements 111 to 113 in each of the lighting fixtures 103A and 103B are respectively All a contacts are turned on by the switch control unit 110. As a result, the light emitting diode 108 and the secondary battery 109 in each of the lighting fixtures 103A and 103B are connected in series between the power input terminals, and thus the light emitting diode 108 is turned on by the output from the power supply device 102. The secondary battery 109 can be charged. Note that since the secondary battery 109 is charged by trickle charging in which a weak current is continuously supplied, current does not flow to the light emitting diode 108 when the secondary battery 109 is fully charged.

  On the other hand, in an emergency in which the AC power supply 101 is in a power failure state, the switch element 107 is turned off by the power failure detection circuit 104 in the power supply device 102, whereby the power supply device 102 stops outputting. At this time, the first to third switch elements 111, 112, and 113 are switched to the b-contact side by the switch control unit 110 in each of the lighting fixtures 103A and 103B. By this operation, in each lighting fixture 103A, 103B, the secondary battery 109, the current limiting circuit 114, and the light emitting diode 108 form a closed loop circuit through the second and third switch elements 112, 113, respectively. This closed loop circuit is disconnected from the power input terminal by the first and third switch elements 111 and 113, and therefore the light emitting diode 108 is turned on using the power charged in the secondary battery 109. Here, the current limiting circuit 114 adjusts the current flowing through the light emitting diode 108.

  Furthermore, when the AC power supply 101 recovers, the switch element 107 in the power supply device 102 is turned on again, and the power supply device 102 resumes supplying current to the lighting fixtures 103A and 103B. By this operation, the switch control unit 110 in the lighting fixtures 103A and 103B switches the first to third switch elements 111, 112, and 113 to the contact a side, and the output of the power supply apparatus 102 is the same as in the normal state. Thus, the secondary battery 109 can be charged while the light emitting diode 108 is turned on.

  Therefore, according to the emergency lighting system 100, by using the light emitting diode 108 as the light source, the power supply device 102 can be disposed at a position away from the fixture main body of the lighting fixtures 103A and 103B having the light emitting diode 108. Therefore, the lighting fixtures 103A and 103B can be downsized (thinned). In addition, since the secondary battery 109 serving as an emergency power source for turning on the light emitting diode 108 in an emergency is provided in the fixture body of each lighting fixture 103A, 103B, the light emitting diode of each lighting fixture 103A, 103B in an emergency. Therefore, the capacity of the secondary battery 109 can be determined regardless of the number of lighting fixtures 103A and 103B connected to the power supply apparatus 102. That is, even if the number of lighting fixtures 103A and 103B increases or decreases due to a change in the layout of the building, it is not necessary to change the capacity of the secondary battery 109.
