Description

Variable combination emergency induction light

The present invention relates to a variable combination type emergency induction lamp, and more particularly, to an improvement in the configuration of an emergency induction lamp such as a night emergency induction lamp and an indoor emergency induction lamp having an increased lifespan and an effect.

In most buildings, emergency induction lamps should be installed in accordance with related laws.

Such an emergency induction lamp is a means for allowing an indoor resident to easily detect an emergency door in an emergency such as a fire. Therefore, emergency guidance is essential in theaters and entertainment facilities where many people gather.

Emergency induction and the like for this purpose had been conceived from a variety of types from the prior art had the following problems.

First of all, although emergency induction lamp is used as a marker that there is an emergency door at a specific position without the purpose of lighting, it is a rough box type and a translucent emergency induction light box on the front side.

In addition, due to the built-in transformer and ballast for high-voltage discharge of fluorescent lamps, there is considerable waste of power due to the waste of materials and emergency induction lamps that must be turned on continuously. Power is wasted.

In addition, since the fluorescent lamp occupies a predetermined volume, it is difficult to reduce the size thereof, thereby having a problem in that the mounting position is limited, and having a constant service life, thus making it inconvenient to perform frequent replacement.

As an additional problem, most of the emergency induction lamps are printed on the translucent plate such as transparent plastics on the front, and the words “EXIT”, “IN”, “Emergency Exit”, etc. are required to be re-installed when changing the structure of the building. Have.

For example, when the emergency door used as the exit was used as the entrance due to the structural change, the cumbersome to install a separate emergency induction lamp existed and the waste of resources was severe.

The variable combination type emergency induction lamp of the present invention devised in view of the problems of the above-described conventional induction lamps is intended to replace various light emitting means and to have various applicability as a combination structure of variable light emitting means.

Variable combination type emergency induction of the present invention for achieving the above object;

A circuit board in a box-shaped induction lamp casing and a light-transmissive display window on its front side are provided with an LED segment which is a light-emitting diode combination that can display specific characters as a light-emitting diode combination.

The circuit board is provided with a transformer, rectifying diode, surge protection and ripple elimination capacitor, reverse voltage prevention diode, battery charge remaining protection, and a step-down and direct current charging circuit such as a transistor to display any set characters by emitting light. ;

The light emitting diode array may further include a plurality of contact setting switches for selectively connecting display setting characters to a power supply via a resistor.

The configuration and operation effects of the variable combination emergency induction lamp of the present invention together with the accompanying drawings will be described in more detail.

1 is a perspective view showing one embodiment of a variable combination type emergency induction of the present invention, FIG. 2 is a plan view showing one example of a variable combination type emergency induction of the present invention, and FIG. 3 is a variable combination type emergency induction of the present invention. 4 is a circuit diagram of a configuration suitable for application to a variable combination emergency induction lamp or the like of the present invention.

In Fig. 1 showing the configuration of the variable combination emergency induction lamp of the present invention as one specific example;

Inside the outline box-shaped induction lamp casing 1, a circuit board 2 having the circuit of FIG. 4 is mounted. In addition, the LED display 10, which is a light emitting diode combination of the present invention, is attached to the front display window 3 of the induction lamp casing 1.

The LED segment 10 is formed of a partially divided light emitting diode that displays characters required for emergency induction, such as "EXIT" and "IN" characters, as in a conventional light emitting display device. It is configured as a combination.

This is to form a plurality of divided light emitting diodes (11, 12, 13, 14 ...), respectively, in the same manner as in the general method, and to connect the cathode or anode electrodes of the light emitting diode 11 as a common connection or a distribution connection. It is composed.

On one side of the induction lamp casing 1, a setting switch 20 for selectively displaying one of the characters " EXIT " or " IN "

A circuit diagram of the variable combination emergency induction lamp of the present invention for implementing such a configuration is shown in FIG.

The electric power supplied from the indoor power source and the emergency power auxiliary device (not shown) is stepped down through the transformer T,

This stepped-down current has a conventional rectifier circuit filtered by the diodes D1 and D2 for rectification, and a capacitor C for surge suppression and ripple cancellation. ) Is supplied to the storage battery (B) by

At the same time, the light emitting diode array LA, which is a display element, is supplied via a voltage smoothing resistor R2.

A transistor (TR) is used as a charge remaining protection to provide a high resistance (R3) for preventing the overcurrent to prevent the battery life from being reduced by charging the overcurrent at the start of charging and to prevent complete discharge of the battery during prolonged outages. Provide the wiring.

Therefore, the light emitting diode array LA for light emitting display is driven with the above step-down and peaceful low voltage, and at the same time the respective light emitting diodes 11, 12, 13, 14... It is driven through the resistors R5, R6, and R7. As the setting switch 20, only the light emitting diodes corresponding to the letters "EXIT" and "IN" are driven.

If the letter "EXIT" is selected as the setting switch 20, only the corresponding light emitting diodes 11, 12, 13, and 14 are driven, and when "IN" is selected and set, the corresponding light emitting diodes are also selected. What is necessary is just to comprise the structure which connects the exclusion state of the LED segment 10 as a switch which has many ON-OFF connection terminals only (11,12,13,14 ...).

Of course, the characters of the display unit may be implemented as Korean, not English, and this implementation may change the combination of the excretion state of the LED segment 10 configured as the light emitting diodes 11, 12, 13, and 14. By doing so.

The light emitting diodes 11, 12, 13, and 14 used in the present invention preferably have yellow or green light of relatively low power and high brightness.

In the variable combination type emergency induction lamp of the present invention described above, since each element of the circuit is mostly a passive element, its size is very small, it can be compactly mounted on the circuit board 2 so that the induction lamp casing of the overall emergency induction lamp ( 1) It can be thinly made so thin that it can be extremely thin in appearance when it is installed in emergency doors.

In addition, by using the driving display unit as a light emitting diode, it is possible to drive for a long time with extremely low power consumption, and to have a separate charging configuration, so that a predetermined purpose can be achieved even during a power failure.

The variable combination emergency induction lamp of the present invention of the above configuration can be selected arbitrarily arbitrary display characters,

By using the drive display means as a combination of the light emitting diodes, the power consumption is minimized, and the frequent replacement work due to the end of the life of the fluorescent lamp as in the conventional configuration has unnecessary utility.
