Description

Multifunctional projection induction light {MULTIFUNCTIONAL PROJECTION EXIT LIGHT}

The present invention relates to an induction lamp, and more particularly, to implement the pictograms of the induction lamp using projection and multi-function including an alarm function and video communication function between the evacuator and the central control room to help the evacuation of the evacuation quickly. It relates to projection induction lamps.

In general, in case of an emergency such as a fire or a power outage in a place where people live or travel, such as buildings or subways, exit lights are installed at predetermined positions inside the buildings or subways for emergency evacuation of people. They are then able to evacuate to a safe place quickly according to the instructions of the judo lights.

In general, as a conventional induction lamp, a form in which a predetermined light source is inserted into a box made of a plastic material in which a pictogram indicating an exit or a passageway is formed is commonly used.

Conventional induction lamps are classified into small, medium, and large according to their size, and are divided into single or double sides according to the display surface. Is displayed.

division small type Medium large Usage Display surface section both sides section both sides section both sides Evacuation port Left O O O O O O Right O O O O O O amount O O O O O O radish O O O Passage Left O O O O O O Right O O O O O O amount O O O O O O Up and down O O O

Referring to Table 1 above, it can be seen that there are 42 kinds of pictograms (evacuation signs), so that about 42 kinds of pictograms are silk-printed on the plastic display surface, and then appropriate pictograms according to the places are provided. Selected induction lamps were installed.

Conventional guide lights are fixed to the wall or ceiling of a building with the overall shape and size and pictogram signs fixed, providing optimal visibility to refugees without considering the distance between them and the brightness of the guide lights. There is a problem that can not be.

In addition, evacuation signs such as induction lamps installed in buildings have been installed by setting the direction of evacuation prior to the fire, so when an actual fire occurs, some evacuation signs of induction lamps may be displayed in the opposite direction to the direction of evacuation. There is a serious problem of failing to save a life that can arise and be saved.

The present invention has been proposed to solve the above problems, an object of the present invention is to provide a projection induction lamp such that the pictogram is implemented by projection.

Another object of the present invention is to provide a multi-function projection induction lamp that can display a variety of pictograms (evacuation cover) with a single induction light by displaying the selected pictograms according to the selection signal after preparing a plurality of pictograms.

Another object of the present invention can transmit the image of the site to the central control room in an emergency situation, and can communicate in both directions, pictograms of the induction lamp so as to induce evacuation in the correct direction according to the situation of the site (evacuation signs) It is to provide a multi-function induction lamp that can be switched remotely.

In order to achieve the above object, the projection induction lamp of the present invention is a light source; A glyph plate disposed to be spaced apart from the light source to selectively transmit light generated by the light source to generate a glyph image; An optical mechanism for optically processing the glyph images to form glyphs on a screen; And a screen displaying the glyph passing through the optical mechanism.

The screen may be a single-sided or double-sided screen, and the pictograph includes a plurality of pictograms, and the projection induction lamp may further include a pictograph selector to select and display one of a plurality of pictograms on the pictograph. have.

The pictograph is a plurality of cut films that horizontally surround a light source and have several pictograms set on a surface thereof, and display animation induction lamps by sequentially projecting the set pictograms onto the screen while rotating along the central axis of the cylinder. . In addition, the film is a disc disposed vertically between the light source and the screen and set a number of glyphs at the edges, and displays the animation induction lamp by sequentially projecting the set glyphs to the screen while rotating along the central axis of the disc can do.

The projection induction lamp is a front projection type that the projector projects on the front of the screen or a rear projection type that the projector projects on the back of the screen. The rear projection type projection induction lamp is an integrated type that is integral with the projector and the screen. It may further include a lamp for illuminating the evacuation passage in an emergency.

In addition, in order to achieve the above object, the system of the present invention is connected to the central control room, a plurality of multi-function induction lamps installed in the walls, passages, lobbies, etc. of each building or subway, and the plurality of multi-function induction lights connected to the central control room. In the multi-function induction lamp system consisting of a network for the, The multi-function induction lamp comprises a pictograph display for selecting and displaying one of a plurality of pictograms in accordance with the selection signal (SEL); A microphone and a speaker capable of two-way communication with the central control room by voice in an emergency; A camera module for photographing an on-site situation in an emergency and transmitting it to the central control room; And transmitting a voice input of a microphone and a video signal of a camera to the central control room, outputting a guide voice of the central control room through the speaker, and interpreting a command received through the network to convert the pictogram display into a pictogram selection signal. It consists of a communication unit for controlling.

According to the projection induction lamp of the present invention, the pictogram display surface is separated from the projector portion, so that the position and size of the pictogram display surface can be easily changed by appropriate adjustment in the projector portion, and the display surface can be used as a double-sided type. There is an advantage.

In addition, the projection induction lamp of the present invention may display various types of pictograms by the same induction lamp by displaying a pictogram selected according to a setting or a remote selection signal after preparing a plurality of pictogram signs, and thus the evacuation route is changed accordingly. It is easy to use because there is no need to replace the induction lamp, and the direction of the sign of the induction lamp can be switched in the central control room so as to evacuate in the right direction according to the location of the fire.

In addition, the projection guidance lamp according to the present invention may display dynamic pictograms such as animation when the pictograms are sequentially and repeatedly displayed after the pictograms are prepared as pictograms to be a series of animations.
