Description

Emergency exit guidance indicator integrated lighting device {LIGHTING APPARATUS WITH EMERGENCY LEAD LAMP}

The present invention relates to a lighting device integrated with an emergency exit guide light. More specifically, it operates as a lighting light in daily life, but in an emergency, the function of the lighting light is stopped and an emergency exit guidance sign is displayed at the same time, so that the lighting light and the emergency exit guidance light are installed separately. This relates to a lighting device integrated with an emergency exit guidance indicator that can effectively reduce casualties in an emergency by quickly inducing evacuation through emergency passageways while significantly reducing cost and space.

In multi-use facilities such as subway stations, terminals, department stores, commercial buildings, and government offices, emergency exit guidance lights are installed to indicate the location or direction of emergency exits or emergency passages to reduce casualties in emergencies such as power outages or fires.

In addition, large-scale buildings such as apartments and officetels are required to install various facilities to ensure the safety of residents, and one of these safety facilities is an emergency light that turns on when a power outage occurs.

These emergency exit guidance lights are used under various names depending on the installation location, such as emergency lights, evacuation guidance lights, and fire alarm lights, but they have in common that they are used to reduce casualties by quickly guiding evacuation through emergency passages in an emergency.

Emergency exit guide lights as described above include an embedded type that is embedded in the wall, and a protruding type that is fixed by attaching a fixing bracket to the ceiling or wall and fixing the guide light case to the fixing bracket in a hanger manner.

Meanwhile, Domestic Utility Model Registration No. 20-0495990 (registration date: October 4, 2022) includes a base frame in which a light source and a circuit display LED board are placed; It is detachably installed on the front part of the base frame, and the front part is composed of three sides. Among the three front parts, one front part is arranged to protrude at a certain distance toward the front, and one of the front parts is disposed at a certain distance. A front frame in which two other front parts are disposed inclined at an angle of 120 degrees from both ends of the front part, forming a diamond shape when viewed from a plane; a first sign, a second sign, and a third sign detachably coupled to the front portion of the three sides; In the indoor emergency guidance light for buildings that includes a mark formed on the back of the base frame to guide the direction of the emergency exit, allowing the emergency exit direction to be visually confirmed from four directions, a speaker is installed on the lower surface of the base frame or the front frame. or a flashing light, at least one is installed, a coupling groove is formed on each front flange of the front frame, and coupling protrusions for insertion into the coupling grooves are formed on the first to third signs, First magnets are installed on both sides of the coupling protrusions, and second magnets having a different polarity from the first magnet are installed on both inner surfaces of the coupling grooves, and the first sign to the first sign to each front part of the front frame are installed.

As shown, it is configured to be mounted inside a rectangular lighting case 12 with an open upper surface.

The diffusion plate 10 is disposed on the upper surface of the display light guide plate 20 and functions to provide uniform illumination visibility by scattering the light coming out of the light guide plate surface and spreading the light evenly across the light guide plate surface. .

This diffusion plate 10 preferably has a high light transmittance to reduce the amount of light absorbed, and haze (turbidity) must be high to prevent the scattering pattern formed on the display light guide plate 20 from being reflected.

The display light guide plate 20 and the lighting light guide plate 30 may be composed of a transparent acrylic panel that is disposed on the side and turns a point light source or line light source emitting light into a surface light source. The display light guide plate 20 operates as an emergency exit guide light in an emergency situation, and the lighting light guide plate 30 operates as a lighting light.

The display light guide plate 20 has a scattering pattern portion 50 formed at the center of the upper end for guiding emergency exits.

In one embodiment, the scattering pattern portion 50 may be configured in the shape of an arrow as shown in FIGS. 1 and 2, but any pattern for indicating the direction of an emergency exit can be applied.

The scattering pattern portion 50 may be formed as a dot-print or line-shaped print or groove on or inside the display light guide plate 20. This scattering pattern portion 50 scatters the light incident through the side so that it is diffusely reflected so that the pattern of the scattering pattern appears to the outside. Here, the scattering pattern portion 50 may include a scattering agent, and the size and spacing of the dots or lines forming the scattering pattern can be appropriately adjusted so that the emergency exit guidance sign is clear.
