LED flat-plate luminous fire-fighting evacuation display apparatus of the present invention adopts the technical scheme of the flat-plate luminous plate technique of LED sheen to be: the poly (methyl methacrylate) plate of substrate (1) employing anti-flaming transparent or fire-retardant plastic plate or transparent optical fibers plate or limit end face of clear glass periphery or 2 limit end faces or 3 limit end faces or 4 limit end faces advance LED (2) with hole or the latent edge of groove, or the light-emitting area of LED (2) tightly vertically is attached to the substrate periphery end face, the light directive substrate inside of LED, with fire-retardant lighting material at a surperficial silk-screen fire-fighting evacuation figure of substrate (3), LED powers with fire-fighting power supply (4), keep LED on the one hand with frame (5), on the one hand LED is hidden straight next, the outside people can't see LED, external fire-fighting power supply module links to each other with LED with fire-retardant lead (6), play the floor light effect simultaneously, realize double-side simultaneously.Thickness can be accomplished 3～10mm, decides on the LED size of employing.

The effect of fire-fighting power supply is: under normal circumstances, LED gives the charging of the rechargeable battery in the fire-fighting power supply simultaneously with the mains-supplied in the fire-fighting power supply, in case outage, then the rechargeable battery in the fire-fighting power supply is powered to LED.

Another technical scheme is: coat with fire-retardant lighting material seal entirely on surface of substrate, when the LED electrified light emitting, through complicated optical principle, the whole surface of substrate is all luminous, the lighting material of another surface of substrate with above-mentioned different colours, print fire-fighting evacuation figure, what these fire-fighting evacuations figure saw naturally is also very clear, literal among the fire-fighting evacuation figure, the lighting material of pattern, digital available different colours is printed, then better distinguish each part of these figure, different glow colors then appears in whole fire-fighting evacuation figure.When cutting off the power supply, still give civil power people more eye-catching.

Another kind of technical scheme is: the known light guide plate of substrate, and the fire-fighting evacuation indication directly is printed on the substrate front surface with lighting material, the light source led electrified light emitting, then the fire-fighting evacuation index map is very clear.Also can tightly be attached to the light guide plate surface, add frame, still give people also very eye-catching during the civil power outage with printing the fire-fighting evacuation index map on the anti-flaming transparent plate.

Another kind of technical scheme is: adopt thin lamp box structure, inlay LED in four frames, the LED parallel panel, the LED light-emitting area is inwards, fire-fighting evacuation figure is printed on the inner surface of wherein outer transparent area, small-sized because of LED, lamp box structure can be accomplished the following thickness of 10mm, when LED is luminous, fire-fighting evacuation index map on the transparent panel is also very clear, during the civil power outage, fire-fighting power supply is powered to LED, and it is very clear that the evacuation pattern also can be seen.

Above-mentioned several technical scheme, so fire-fighting power supply can be external, within one meter of fire-fighting evacuation display apparatus, also can be built in the fire-fighting evacuation display apparatus frame within the general 5W of power because of LED is that used fire-fighting power supply power of low energy-consumption electronic device and size are all little.

Good effect of the present invention is: above-mentioned several schemes, the LED of light source because of all adopting, even the fire-fighting evacuation index map all can be seen by people very clearly can accomplish low-power, high life, the outage of brightness height civil power the time, because of active illuminating very eye-catching; Employing divides the position to adopt lighting material without color without the LED of luminescent spectrum and pattern, luminous can multiple color, also can realize double-side.
