In a possible embodiments, described circuit board edge dual-side up and down respectively is provided with a fixed edge frame.

In another possible embodiments, described slot is the specification that general fluorescent tube can be planted.

In another possible embodiments, described emergency power source is a rechargeable battery.

In a possible embodiments again, after described circuit board, a plurality of light emitting diode, converter and emergency power source assemble and finish, further be provided with one around the enclosing cover layer that coats above-mentioned member periphery.

The utility model is formed simple structure, and minimizing takes up space, and saves cost and reduces power consumption, more cooperate and commonly use the fluorescent tube slot, can directly be installed in old power supply slot, need not change the whole structure of forming, easy to use, thus a kind of brand-new light emitting diode emergency lighting device formed.

The specific embodiment

For can be further structure, use and the feature thereof of the utility model being had darker one deck, preferable embodiment is enumerated in clear and definite, full and accurate understanding and understanding, cooperates graphic being described in detail as follows:

At first see also Fig. 2, shown in Figure 3, in one of the diagram preferred embodiment, the light emitting diode emergency lighting device system of the utility model comprises a lamp box 20 and a light fixture 30 at least, described lamp box 20 wherein side is set to the photic zone 21 of a light-permeable, and a pair of slot 22 for light fixture 30 plants, the specification that this slot 22 can be planted for general fluorescent tube are set in inner edge.

Described light fixture 30 central authorities are provided with a circuit board 32, with this circuit board 32 as pedestal, and all the other members are set in its front and rear surfaces, at first a plurality of light emitting diodes 31 laterally in a row are inserted in the photic zone direction surface of circuit board 32 in the face of external shell, the color of this light emitting diode 31 is regardless of, usually use comparatively showy white light or gold-tinted, to improve the identification degree.

The 21 direction surfaces in circuit board 32 back to photic zone, be provided with and connect a converter 33, it is arranged at circuit board 32 antarafacial mutually respectively with light emitting diode 31, avoid stopping light emitting diode 31 light emitting paths, and converter 33 and an outside simultaneously power supply and an emergency power source 34 that connects general supply, this emergency power source 34 also is arranged at circuit board 32 back to photic zone 21 direction surfaces.

See also Fig. 4, converter 33 as shown is one to have the member of identification capability, can switch the action of power resources automatically, when converter 33 detects general power supply when being path, promptly use general power supply as power source, if converter 33 detects general power supply when opening circuit, promptly very first time use emergency power source 34 supplies light emitting diode 31 luminous required electric powers as power source.

In another possible embodiments, emergency power source 34 is a rechargeable battery, detect general power supply when being path at converter 33, promptly use general power supply as power source, and simultaneously to emergency power source 34 action of charging, make emergency power source 34 reusable, avoid changing because of electric power exhaustion.

Because the member that above-mentioned light fixture 30 comprises is arranged at the plane, circuit board 32 front and back as substrate respectively, for avoiding circuit board 32 stressed bending even distortion, lower edge further respectively is provided with and attaches a fixed edge frame 35 on circuit board 32, this fixed edge frame 35 is made with rigid material, and using increases light fixture 30 overall construction intensity.

For preventing that above-mentioned composition member from directly contacting with outside, it is dirty to be infected with dust etc., in members such as light emitting diode 31, circuit board 32, converter 33 and emergency power source 34 assemble fixing after, further be provided with one around the enclosing cover layer 36 that coats above-mentioned member periphery, reach the effect of isolation, and allow the user in the time must changing light fixture 30, can directly hold and get enclosing cover layer 36, avoid touching internals.

In a preferred embodiment, described enclosing cover layer 36 is made with transparent material, allows light fully be dispersed.

As shown in the figure, converter 33 outwards connects the plugs 37 of general supply power supply, and it is corresponding that this plug 37 is set to slot 22, makes the light fixture 30 of the utility model can directly be installed in old power supply slot, need not change the whole structure of forming, and reduces cost and easy to use.

Because of indication emergency lighting device on the market, except that being installed in wall and ceiling intersection, necessity on the ceiling of being suspended in is also arranged, the external shell of this kind emergency lighting device is taked all designs of light-permeable of two sides, but since light emitting diode be a kind of only can be towards the article of unidirectional illumination, therefore for shining two directions simultaneously, see also Fig. 5, Fig. 6, in the another possible embodiments of diagram, two circuit boards 32 be arranged in parallel, side surface a plurality of light emitting diodes 31 of planting outside two circuit boards 32, and connect converter 33 one by one in inner surface, emergency power source 34 and plug 37 are used the general power supply of transmission.

The utility model reaches the Emergency Light effect via the effect between above-mentioned member, avoids the shortcoming that assembly is various in the located by prior art, circuit is mixed and disorderly, further saves cost and reduces power consumption, thereby form a kind of brand-new light emitting diode emergency lighting device.

The above, it only is the preferred embodiment of the utility model, when the scope that can not limit the utility model enforcement with this, promptly the simple equivalent of being done according to the utility model claim and utility model description generally changes and modifies, and all must include in the utility model claim.
