Description

  The present invention relates to emergency lighting devices such as guide lights and emergency lights.

  This type of emergency lighting device is used for emergency lighting in a building for a specified period of time in order to clearly indicate the evacuation route and to ensure lighting in the event of a power failure due to a fire. The secondary battery power is turned on with an emergency light. Therefore, the inspection of this secondary battery has been obligated by the Fire and Disaster Management Agency Notification and the Building Standard Law, and whether or not the secondary battery as an emergency power source can be lit for the specified time. One of the important factors is that inspection can be easily confirmed.

  For this purpose, in the conventional guide light 100 having the display panel 102 on which the pictogram indicating the evacuation direction is drawn according to the external view of FIG. 4, whether or not the lamp can be lit with electric power from the secondary battery power supply. For example, by manually operating the inspection switch 103 formed by a push switch and disposed on the outer surface of the instrument body 101, the power input from the commercial power supply to the control circuit is cut off for a moment to switch to the power supply from the secondary battery. At present, the judgment is made by lighting the lamp.

  However, in the inspection contents such as the inspection switch 103, the function of surely lighting the lamp, whether or not the actual battery function is achieved by actually lighting the lamp for 20 minutes or 60 minutes, for example, with the secondary battery power source. The confirmation is not enough. In the figure, reference numeral 101 denotes an instrument body, 102 denotes a display panel, 103 denotes an inspection switch, and 104 denotes a charge monitor composed of an LED or the like indicating the state of the secondary battery. FIG. 5 is a diagram showing the internal configuration of the guide lamp 100, where EB is a battery (secondary battery), 105 is a lamp, 106 is a terminal block for supplying commercial power AC, 107 is a lighting device, FIG. 6 is a circuit configuration diagram of the lighting device 107, in which 108 is a power supply circuit, 109 is a charging circuit, 110 is a lighting circuit formed by an inverter circuit and the like, and 111 is a control circuit for the lighting device 107 as a whole.

  That is, in the emergency lighting device having the above-described configuration, the battery function check confirmation for performing the function check for continuously lighting the lamp 105 with the secondary battery EB for a predetermined time is not performed. Therefore, as another inspection method for this, a branch breaker of a dedicated branch circuit for emergency lighting devices such as guide lights and emergency lights can be used without operating the individual inspection switches for each emergency lighting device. It has also been proposed to automatically check the secondary battery power supply of all emergency lighting devices connected to the branch circuit after a predetermined time, that is, 20 minutes or 60 minutes by opening the circuit.

  Further, for example, in JP-A-8-185987, as an emergency lighting device, lighting means for supplying power from a commercial power source to light a lamp and a battery (secondary battery) connected to the commercial power source are charged. And an emergency lighting device having control means for controlling power supply to the lamp from the commercial power source and the battery. The control means includes an inspection sequence means for the battery, and a predetermined inspection switch is provided. There is disclosed a technique having timer means for starting the operation of the inspection sequence means when the ON operation is longer than the time.

  According to this technology, the inspection sequence starts automatically when the inspection switch is turned on for a short period of time. Therefore, for example, by detecting the rate of decrease in battery discharge voltage or discharge current, The prediction is made, and the function check of the lamp lighting by the secondary battery that requires 20 minutes or 60 minutes is shortened in time, and the effect can be confirmed.

However, when the inspection switch is automatically turned on only by turning on the inspection switch for a short time, the operation of the inspection switch is operated when the inspection switch is operated by an unspecified person. It is also assumed that the secondary battery power supply is not fully charged when an actual fire occurs. Therefore, there is a concern that the problem that the lamp does not continuously light for a predetermined time during the evacuation guidance is concerned.
