Description

LED emergency induction device including emergency status notification function {LED EMERGENCY LIGHTING APPARATUS WITH INFORMATION FUNCTION OF EMERGENCY SITUATION}

The present invention relates to an LED emergency induction device for operating an emergency induction light that informs the evacuation exit in an emergency by using an LED, and includes an LED blink function in the LED emergency induction device to blink an additional LED only in an emergency. It is a device to inform the status and to help people quickly recognize the emergency induction, etc. to help the evacuation.

Emergency guide lights are installed in the corridor of buildings and other proper locations to turn on in case of a fire or other emergency and direct people to the direction of evacuation. Most emergency guide lights, which are generally installed and used, use fluorescent lights. The used device is applied. However, recently, due to the development of semiconductor and power electronic technology, there are increasing cases of applying LED as an illumination source by adopting LED which has the advantages of low power consumption, semi-permanent life and low voltage operation in the lighting field. In the field of emergency induction lamps, LED emergency induction lamps using LEDs instead of fluorescent lamps have been developed and are gradually expanding their scope of application.

In the operation of the conventional fluorescent emergency induction light device, the switch is attached to the emergency induction light device, and when the exit indication can be identified by natural light during the day, the fluorescent light is turned off, and the fluorescent light is turned on at night when it is difficult to identify the exit indication. It is a way to inform the exit sign. However, this method has to be turned off during the day, and to be turned on at night, which is accompanied by inconvenience of managing the lighting and turning off the fluorescent lamp on time. If the timing of the fluorescent lamp is not turned off during the day, the fluorescent lamp is continuously turned on, resulting in waste of energy due to power consumption. If the timing of the fluorescent lamp is not turned on at night, the exit indication cannot be identified. Therefore, in order to solve this problem, by developing LED emergency induction device with low power consumption and lighting continuously during daytime, emergency induction lamp device which is easier to manage and save energy than emergency induction device using fluorescent lamp. It became possible.

Looking at the operation of the LED emergency induction lamp device, the power is normally supplied from the commercial power source to keep the LED always lit, and at the same time to charge the battery contained therein to always maintain a fully charged state. Therefore, when commercial power is normally supplied regardless of day or night, the LED is turned on by commercial power. When the power is not available due to an error in the commercial power, the LED is turned on for a certain time by receiving power from the battery. It will always be possible to identify exit markings.

1 is a diagram schematically illustrating a configuration of a conventional LED emergency induction device, and with reference to FIG. 1, the LED emergency induction device 1 is rectified by receiving a commercial AC power source 2. After converting alternating current into direct current through the circuit (3), the LED lamp (6) is turned on through the switching mode power supply (4). At this time, since the converted direct current is a direct current containing a large amount of pulsating components, the control of the PWM control circuit unit 5 reduces the pulsating components and converts it into a stable high-quality direct current.

On the other hand, the LED emergency induction device (1) includes a storage battery (7), when the commercial power supply (2) is always in the fully charged state of the storage battery 7 through the output voltage of the switching mode power supply (4) When the normal commercial power supply 2 is not supplied, such as a power failure, the battery 7 discharges the voltage charged in the battery 7, thereby continuously lighting the LED light 6 until the voltage of the battery is discharged. do.

However, the conventional LED emergency light apparatus 1 shown in FIG. 1 has the following problems. Prior to the detailed description, the LED emergency induction apparatus 1 as described above should be able to identify an evacuation exit at all times by maintaining an appropriate brightness, as well as a) maintaining high energy efficiency, b) in an emergency It must be clearly visible to the perplexed person, c) be able to be recognized even in smoke during a fire, d) the LED should be normally lit by the battery voltage during a power outage, and so on.

The issue of energy efficiency in all energy-consuming devices is so important that it cannot be overemphasized. In addition, the exit indication function, which is the original purpose of the emergency induction system, should be possible in any situation. In other words, in case of emergency such as power failure or fire, emergency induction lamp should maintain constant brightness so that people can easily recognize the direction of exit. The above requirement is a requirement that must be fulfilled, given that the ability to capture the evacuator's eyes will quickly recognize the direction of the evacuation exit.

Looking at the conventional LED emergency light apparatus 1 shown in FIG. 1 in this respect has the following problems. The LED emergency induction device 1 of the related art has no distinction between normal and emergency in terms of appearance. In other words, the LED light is normally lit to indicate the exit direction, and the same LED light is lit to indicate the exit direction even in the event of a fire or an emergency, so that there is no difference between the normal and emergency operating states. In the event of a fire in a building, people in places other than the fire may not be aware of the fact that they may miss the time to evacuate quickly at the beginning of the fire.

In addition, the LED emergency induction apparatus 1 of the related art, as described above, simply maintains the state in which the LED light is turned on, so that it is not possible to find the exit in the state of embarrassment in an emergency and draw attention from those who are left and right. There is a lack of functions such as emergency induction, which should allow the exit direction to be recognized.

The present invention was devised to solve the above problems, and the purpose of the present invention is to inform people that an emergency has occurred to enable rapid evacuation by making an emergency operation requiring an emergency evacuation appear different in appearance. There is a purpose. In other words, only the LED lights up to indicate the direction of the evacuation exit, and if an emergency occurs, including a fire, at other locations other than the current location, it detects it and flashes a separate red LED to generate an emergency situation for people. It aims to inform the evacuation so that the evacuation can be made quickly.

In addition, the present invention, as described above, is intended to enable people to quickly recognize the direction of the evacuation exit by blinking the red LED light when people emerged when an emergency occurs.
