Description

  The present invention relates to a method for refurbishing an emergency lighting device into an LED-compatible emergency lighting device that enables an emergency lighting fixture to be changed from a fluorescent lamp to a light emitting diode (hereinafter referred to as LED) at low cost.

  Conventionally, an emergency light in a building or the like is switched to a battery at the time of a power failure, and is lit for at least 30 minutes by law.

  In recent years, work has been increasing to adopt LEDs that have a longer lighting time and a longer service life than existing emergency lights such as fluorescent lamps. All related equipment was also replaced.

JP 2004-185875 A

  As described above, when an LED is used instead of a normal fluorescent light used for an emergency light, the existing emergency light device with a circuit structure for the fluorescent light cannot be used alone, but the LED is modified. All equipment was replaced, including equipment that did not need to be replaced. For this reason, there is a problem that the time required for construction and the cost of equipment are increased.

  Therefore, the present invention was created in view of the existing circumstances as described above, and when changing an emergency lighting fixture such as a fluorescent lamp to an LED, it is possible to cope with an inexpensive construction cost. The purpose is to provide a repair method to the corresponding emergency lighting system.

  In order to solve the above-described problems, the present invention is compatible with an LED in which an LED driver driving unit and a battery / LED driver circuit are additionally connected to a battery charging circuit in an existing emergency light ballast for a fluorescent lamp. The battery charging circuit is modified so that the fluorescent lamp can be converted into an LED lighting apparatus.

  The LED driver driving unit is modified to drive the battery / LED driver circuit and turn on the operation LED connected to the LED connector.

  The emergency light ballast includes an AC / DC selection switching relay for sending DC power to the fluorescent lamp in the event of a power failure, and the relay is interposed between the battery charging circuit and the battery / LED driver circuit. It was modified to be connected to the relay driver drive unit.

  The LED lighting apparatus is attached to an emergency ballast including an LED driver driving unit, an LED-compatible battery charging circuit to which a battery / LED driver circuit is additionally connected, and an LED connector provided in the battery / LED driver circuit. It was characterized.

  ADVANTAGE OF THE INVENTION According to this invention, the repair method to the LED corresponding | compatible emergency illuminating device which enables the change to LED at a cheap construction expense can be provided.

  That is, in the past, all the devices including other devices not related to the LED were replaced in the modification to the LED. However, according to the present invention, only a part of the devices is replaced without doing so. Therefore, the current cost of about 80,000 yen / one place has been reduced to about 30,000 yen. In particular, it is possible to renovate an emergency lighting device that can handle LEDs without removing the electronic ballast for fluorescent lamps.

  Further, since the LED consumes less power, the lighting time of the battery is longer than that of the conventional fluorescent lamp. For example, by using an LED, the same battery that has been on for about 30 to 45 minutes now lasts for 1 hour to 1 and a half hours. Moreover, it is optimal for energy saving and depreciation due to the use of LEDs, and has a great merit by reducing carbon dioxide (CO2).

It is a block block diagram which shows one form for implementing this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the present invention includes an existing electronic ballast 1 connected to an AC power source W, and an emergency light ballast 11 modified so that a fluorescent lamp can be converted into an LED lighting fixture. The emergency light 21 is generally composed.

  The electronic ballast 1 is configured by connecting an electromagnetic wave interference filter 2, a rectifier (+ PFC) 3, a driver / inverter circuit 4, and a resonance circuit 5 in series with each other.

  The emergency light ballast 11 includes an electromagnetic wave interference filter 12, a rectifier (+ PFC) 13, and an AC / DC selection switching relay 14 connected in series. The rectifier (+ PFC) 13 includes a battery charging circuit 15 and a relay. A driver driving unit 16, an LED driver driving unit 17, and a battery / LED driver circuit 18 having an LED connector 18a are connected, the relay 14 is connected to the resonance circuit 5 of the electronic ballast 1, and further the relay 14 Is configured by connecting to the relay driver driving unit 16 and the emergency light 21. The relay 14 of the emergency light ballast 11 switches or selects alternating current to direct current in order to send direct current power to the emergency light 21 in the event of a power failure.

  That is, in the battery charging circuit 15, the resistor R is connected in series between the first diode D1 and the second diode D2, the first diode D1 is connected to the rectifier (+ PFC) 13, and the second second The second diode D2 is connected to the other end of the battery V, one end of which is grounded, and the second diode D2 is connected to the relay driver driving unit 16. The resistor R and the second diode D2 are connected to the LED driver driving unit 17 and connected to the battery / LED driver circuit 18 together with the relay driver driving unit 16. An operation LED is attached to the LED connector 18 a of the battery / LED driver circuit 18.

  As described above, the existing battery charging circuit (not shown) is replaced by the LED-compatible battery charging circuit 15 to which the LED driver driving unit 17 and the battery / LED driver circuit 18 are additionally connected. It can be modified so that it can be converted into a lighting fixture. At this time, the LED driver driving unit 17 is modified so as to light the operation LED connected to the LED connector 18a by driving the battery / LED driver circuit 18.

  The AC power supply W has a power failure test function. That is, it is configured such that a power failure state occurs when the normal power source SW1 is turned off from the on state.

  The current emergency light 21 can be used alone or by switching to a service light. Further, the LED emergency light is the same in length as the current fluorescent lamp, and it is preferable that the LED-like spot-like light cannot be seen.

  Next, an example of the modification method, use, and operation of the configuration configured as described above will be described.

  In the renovation work, an existing battery charging circuit (not shown) is an LED-compatible battery charging circuit 15 to which an LED driver driving unit 17 and a battery / LED driver circuit 18 are additionally connected. Thereby, the emergency light 21 can be converted into an LED lighting fixture.

  At this time, the LED driver driving unit 17 is modified so as to light the operation LED connected to the LED connector 18a by driving the battery / LED driver circuit 18.

  When using the normal power supply (100 to 110V), when the power switch is operating normally when the power switch SW1 is in the ON state, the battery V is charged through the emergency light ballast 11, and the operation LED Lights up.

  At the time of a power failure, when the normal power supply is interrupted, the relay 14 of the emergency light ballast 11 is converted, DC power is supplied, and the operation LED is turned off from the lighting state.

  Also, when performing a power failure test, a power failure occurs when SW1 is turned off from the state where the regular power supply is turned on (SW1 / ON). At this time, the relay 14 of the emergency light ballast 11 is converted, DC power is supplied, and the operation LED is turned off from the lighting state.

  Thus, it is possible to renovate the fluorescent lamp or the like to the LED at low cost only by refurbishing the emergency light ballast 11 as described above.
