With the recent rapid increase in skyscrapers, various facilities inside the building will increase, and in the case of buildings where a large number of residents, such as intelligent buildings, stay, fires at certain places in the building will easily lead to complex and dangerous site conditions. Is predicted. Accordingly, in the event of a fire, there is a further need to accurately identify the location of the fire and to promptly grasp the situation of the fire in order to provide a safe evacuation route at the fire location or to determine whether there are people remaining.

However, in the case of a recent high-rise building, the facilities installed in the building are diversified and complicated. In particular, the wiring for the automated material detection facility increases exponentially as the number of floors increases, and thus becomes very complicated.

In particular, in the event of a fire, people inside the building do not find an exit due to the complex structure of the building and cause a fatal accident if they turn right and left.

As a conventional method for solving such a problem, a method of applying an induction luminous paint to induce an emergency passage on the floor along the internal passage of a facility is often used, but considering the thin coating layer of the luminous paint, luminous efficiency is very high. There is an inefficient problem in that the luminous paint is easily peeled off by the footsteps of the passers-by, and the rework or repair is repeatedly performed due to the short life.

In order to solve the problem of the luminous paint, a number of sensors are installed in a subway station or various buildings to monitor the fire in preparation for an emergency such as a fire, and an emergency light is provided to guide a pedestrian's escape route. In this case, most of the sensors are generally installed on the ceiling, and the emergency lights are usually fixed on the wall or floor.

It is characterized by driving the LED lighting unit and the human body position notification display unit by determining the fire by receiving the received fire detection index.

In the event of a fire according to an embodiment of the present invention, the life location notification LED luminaire has the following effects.

First, after a certain period of time has been spent in order to inform people that there is no evacuation due to the risk of fire because there are no people in this place when there is no human movement, and continuously monitor the movement of people during normal times.
