Description

Emergency indicating sign for neon lamp

The utility model relates to the urgent direction board of a kind of neon bulb, and it has flashing function when having a power failure, belong to the technical field of neon bulb.

Traditional pilot lamp method for making of shutting off power in emergency, just as the bulb type pilot lamp that shuts off power in emergency, make by big can of a rectangle or plastic casing, its volume is bigger, inside is equipped with charging accumulator, the 5V-10V bulb, charging rectifier, power source conversion electrical equipment and indication character calligraph are in translucent glass or milky acryl, be fixed in the can skin again, luminous and show its indication literal through bulb, the back is installed when using, owing to use 5-10 watt of bulb, when urgent, see light clearly as long as there is some smog just can't see, direction board is completely cut off by smog entirely, and under normal circumstances owing to the reason of circuit structure, bulb can not often be lighted, just use power supply in the charging accumulator as often lighting, this accumulator must charge always and supply the bulb electricity consumption, also makes integral device be easy to wear out.

In addition when urgent power source conversion for filling accumulator, it is always at consuming cells electric power, thereby can't make accumulator hold filling electric power, so that the time very shortly is supplied in bulb with regard to unregulated power, if use a power-switching circuit in addition, just often also can light the indication literal, just need to increase by one group of equipment and circuit, its power supply detects in addition, use power supply from the beginning just often, power off time is with filling battery feed, and the method makes complicated its cost that increases of circuit, and volume also increases; Especially its disadvantage is that bulb life generally has only 800 hours, just often also lights bulb, will change the bulb every 30-40 days, different so in the use sense inconvenience.

The general fluorescent lamp type pilot lamp that shuts off power in emergency, still penetrable smog when smog, a slice milky acryl or translucent glass printing word are arranged when making always, it hides in the fluorescent tube front, make fluorescence lose the function that penetrates smog, its structural volume is bigger, power consumption is also high, and charging must be high the peace doubly, and it is very short to be converted to the battery feed lamp tube starting time when urgent, just often can not light the indication literal again, the essential comparatively huge power supply of another group that uses detects change-over circuit and equipment, and cost is also increased, and the fluorescent tube life-span has 5000 hours, the general use just need be changed fluorescent tube in 210-250 days, therefore used limited.

Direction board has plane, is to write printing or engraving in the plane, again by its literal of light-illuminating; Built-in lamplight type is that daylight lamp or bulb are installed in box, and indication literal or pattern are imprinted on translucent glass or the acrylic plate, by the concealable lamp rayed.Transparent offset plate engraving character or pattern type all are that light source is shone in the indentation of literal or pattern by its light importing with the daylight lamp, show by its reflection, fluorescent tube is contained in the box, shine by one side printing opacity, its shortcoming is to be used for in-plant indication, above-mentioned structure can not show significantly, and direction board can not be changed literal or pattern.

The purpose of this utility model is to provide a kind of neon bulb urgent direction board, it can overcome above-mentioned shortcoming, at neon light tube outer cover transparent plastic bearer bar, make the penetrable smog of light, the transparent plastic sheet upper plate reflection in the middle of lamp of indication literal or pattern is by the neon glow that imports all around, make the indication literal more obvious, have the effect that light and indication literal are taken into account simultaneously; Can light the whole year in addition, need not use and fill battery feed, when urgent, can be exchanged into battery supply, and startup flashing circuit, and the life-span of neon light tube is Duoed 20 times than bulb, Duo more than 5 times than daylight lamp, the sculpture techniques of adding indication literal or pattern also can make the light reflection more significantly show.

Fundamental purpose of the present utility model is will solve bulb type or the fluorescent lamp type pilot lamp that shuts off power in emergency to be subjected to the isolated of smog; can't see direction board clearly; under normal circumstances; can not often light; otherwise palpus increase equipment and circuit; make cost increase shortcomings such as increasing overall volume and power consumption height; so in the neon bulb group by a bearer bar protecgulum; tube groove is equipped with in its inside; place on the tube groove with this neon light tube; protecgulum and bonnet make up mutually; the pickup groove circuit board that can lock on the noumenal seat front panel; cover on the noumenal seat and have power hole and louvre and can install electric lake line and can dispel the heat; the indication hornbook has indentation, and spraying one deck beaded glass can reflect the neon glow in week in the indentation, strengthens its display effect; the control circuit of circuit board can be lighted and without charge power supply, be to can be exchanged into to fill battery feed when urgent the whole year.
