Description

  The present invention relates to an emergency lighting device capable of providing a common configuration for various types of emergency lighting devices.

  Emergency lighting devices that ensure floor illumination during power outages are widespread. In general, there are built-in and combined types of emergency lighting devices. The built-in emergency lighting device includes a light source that is turned on in an emergency and a light source that is turned on in a normal state. On the other hand, the combined emergency lighting device lights one light source in an emergency and in a normal time. In addition, cold cathode fluorescent lamps and fluorescent lamps have been used as light sources, but in recent years there is a tendency to use LEDs.

  Conventionally, as an emergency lighting device using an LED as a light source, there has been a guide lamp device that generates an appropriate boosted voltage according to a forward voltage (VF) of an LED module (see, for example, Patent Document 1). In the guide light device described in Patent Document 1, an LED module on which a plurality of LEDs are mounted, a constant current circuit, a detection circuit that detects a forward voltage of the LED module, a booster circuit, and the plurality of LEDs are lit. The switching element is configured to switch between a state and a state in which the plurality of LEDs are turned off at a predetermined cycle. With such a configuration, an appropriate boosted voltage is generated according to the VF of the LED module, and the LED can be efficiently blinked.

  However, as described above, the built-in emergency lighting device and the combined-type emergency lighting device have different configurations, and thus both must be designed separately. For this reason, it takes a long time to develop an emergency lighting device.

  In view of the above problems, an object of the present invention is to provide an emergency lighting device that can be provided with a common configuration in various types of emergency lighting devices and can be easily designed.

  The present invention is an emergency lighting device including a light source unit having a light source and a power supply unit connected to the light source unit.

  In addition, the light source unit includes a booster circuit that adjusts the voltage at the first connection terminal or the second connection terminal to a voltage necessary for lighting the light source.

  The emergency lighting device of the present invention is composed of two units, a power supply unit and a light source unit. Both units are connected by two connection terminals of the power supply unit. The switching circuit provided in the power supply unit connects the light source unit connected to the first connection terminal and the commercial power source at normal times, and turns on the light source of the light source unit by the commercial power source. At the same time, the battery and the commercial power source are connected, and the battery is charged by the commercial power source. In an emergency, the light source unit connected to the second connection terminal is connected to the battery, and the light source of the light source unit is turned on by the battery.

  Further, the light source unit is provided with a booster circuit that adjusts the voltage at the first connection terminal or the second connection terminal to a voltage necessary for lighting the light source. For this reason, when the type and specification of the light source are changed, only the booster circuit needs to be changed, and it is not necessary to change other circuits.

  Further, the light source unit includes a regular light source unit and an emergency light source unit. The service light source unit is connected to the first connection terminal, and the emergency light source unit is connected to the second connection terminal.

  Since the first connection terminal and the regular light source unit are connected, the regular light source unit and the commercial power source are normally connected by the switching circuit described above, and the light source of the regular light source unit is turned on. Further, since the second connection terminal and the emergency light source unit are connected, the light source of the emergency light source unit is turned on in an emergency. This configuration is an optimal configuration mainly for built-in emergency lighting devices.

  Moreover, it has the connection member which connects a 1st connection terminal and a 2nd connection terminal to a single light source unit.

  Since the connection member that connects the first connection terminal and the second connection terminal is connected to the single light source unit, the light sources that are lit in the normal state and the emergency state are the same. This configuration is an optimal configuration mainly for a combined emergency lighting device.

  The light source is preferably an LED.

  In recent years, LEDs have been improved one after another in a short period of time. The emergency lighting device of this configuration can flexibly support not only cold cathode fluorescent lamps and fluorescent lamps but also improved LEDs.

  The emergency lighting device of the present invention can be provided with a configuration common to various types of emergency lighting devices, and the emergency lighting device can be easily designed.
