Abstract
A high reliable LED emergency indicating and signal lamp comprises a shell, a step-down capacitor, a rectifier, a LED array luminescence display screen, an accumulator unit, an accumulator charge and discharge control switching circuit, and a DC converter. The utility model is characterized in that the accumulator unit and the LED luminescence display screen are connected in series, and the rectifier and the step-down capacitor are connected in parallel, which are switched in the commercial power. The high reliable LED emergency indicating and signal lamp is not provided with a power converter with lower conversion efficiency, actually the power consumption is only one third of the corresponding ordinary emergency indicating and signal lamp. The reduction of the power consumption reduces the temperature rising in the light box, which is beneficial to improve the service life of other elements(in particular, for the accumulator). Compared with a switch power, the high reliable LED emergency indicating and signal lamp is not only with high efficiency, but also the used high voltage apparatus is only one capacitor, so the improvement of the reliability of the utility model is quite obvious. In addition, the high reliable LED emergency indicating and signal lamp adopts the capacitor for voltage reduction, thereby the utility model has the advantages of small volume, light weight, low cost, convenient installation and debugging; besides, the utility model also creates advantageous conditions for the super slim of the emergency indicating and signal lamp.
Description
Affiliated technical field the utility model belongs to emergent Warning Mark light fixture, is specifically related to a kind of identification light with emergent deixis of LED of high reliability.
The existing emergent Warning Mark lamp of background technology adopts power frequency supply transformer step-down power supply usually.Cause power transformer self and lamp box internal temperature to raise owing to work continuously for a long time, cause the security reliability of light fixture to descend, shortened Acceptable life.Though adopt Switching Power Supply can further reduce temperature rise in the case, but cost is higher, and security reliability and the not contribution of prolongation Acceptable life to improving light fixture, because Switching Power Supply uses high tension apparatus quantity more, the working stress of device is bigger, and device relatively easily lost efficacy.
Summary of the invention is in order to overcome the integrity problem that existing emergent Warning Mark lamp exists, the utility model provides a kind of LED of high reliability emergent Warning Mark lamp, and it is made up of shell, decompression capacitor, rectifier, charge-discharge control circuit, storage battery, DC converter and led array light emitting display.
The utility model in the technical scheme that is adopted aspect emergent Warning Mark lamp reliability of raising and the prolongation Acceptable life is: under the civil power normal condition, led array display screen and batteries series connection, and adopt the direct step-down power supply of capacitor, be to improve the reliability purpose to simplify circuit design and to reduce power consumption, to reach.
The beneficial effects of the utility model are: the emergent Warning Mark lamp of this high reliability LED does not use the lower power transformer of conversion efficiency, and actual power loss is 1/3rd of common emergent Warning Mark lamp power consumption approximately; The reduction of power consumption has also reduced the temperature rise of lamp box inside, helps improving the useful life of other former device (particularly storage battery).Compare with adopting Switching Power Supply, not only efficient is higher for the emergent Warning Mark lamp of this high reliability LED, and its high tension apparatus arrives less only with a capacitor, so the raising of its reliability is quite obvious.In addition, the emergent Warning Mark lamp employing of this high reliability LED capacitor step-down also has advantages such as circuit is simple, and volume is little, in light weight, cost is low, Installation and Debugging are convenient, and the while also provides convenience for ultra-thinization of emergent Warning Mark lamp;
The description of drawings low-power consumption of the present utility model Warning Mark lamp of meeting an urgent need can be made into single or double as required and show.Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the emergent Warning Mark circuit for lamp principle schematic of the utility model low-power consumption;
Number in the figure is as follows: the F. fuse; R1. current-limiting resistance; C1. capacitor; BRIDGE. rectifier; LED. array light-emitting display screen; BAT. batteries; R3. current sampling resistor; CT. charge-discharge control circuit; DC/DC. DC converter.Capacitor (C1) is a decompression capacitor, plays the step-down effect in the civil power major loop; The effect of rectifier (BRIDGE) is that the alternating current of civil power is changed into direct current; Batteries (BAT) is used for store electrical energy, provides power supply to array light-emitting display screen (LED) during in order to mains failure; Charge-discharge control circuit (CT) by the opening of the charging of batteries (BAT) and discharge control, DC converter (DC/DC), stop controlling, detection, protection and the operating state of civil power and fault indicate several partial circuits to form.The effect of resistance (R1) is to suppress the power supply surge current of moment; Resistance (R2) is the release path that the residual charge on the capacitor (C1) provides when outage.
When plugged, civil power through fuse (F), resistance (R1), capacitor (C1) and rectifier (BRIGE) 1, 3 pin consist of the loop, and 2,4 pin of rectifier (BRIDGE) just have direct current to produce, and (LED) provides the worker to the array light-emitting display screen Make power supply, and accumulators group (BAT) is charged; In order to prevent that batteries (BAT) from overcharging and damage, discharge and recharge Control circuit (CT) detects and controls charging current and the voltage of batteries (BAT) by current sampling resistor (R3).
During the civil power outage, discharge and recharge control change circuit (CT) and will start DC converter (DC/DC) work, battery (BAT) The middle transformation of electrical energy that stores becomes suitable DC current, and supply with array light-emitting display screen (LED) and continue to keep normal luminescence display, Circuit enters emergency rating.
After circuit entered emergency rating, charge-discharge control circuit (CT) constantly detected the discharge voltage of batteries (BAT), When lower the prescribing a time limit that the discharge voltage arrival of batteries (BAT) is set, discharge and recharge control change circuit (CT) and just close the direct current change The work of parallel operation (DC/DC) prevents batteries (BAT) overdischarge and damages that whole circuit all quits work then.
Embodiment is in Fig. 1, and the capacitance of decompression capacitor (C1) is chosen and should be decided according to the capacity and the charging current of batteries (BAT), guarantees can be full of storage battery (BAT) in official hour (24 hours).Array light-emitting display screen (LED) is the polyphone of many light-emitting diodes and connects or the mixed connection array, concrete connected mode also will decide according to the capacity and the charging current of batteries (BAT), as long as can guarantee that every light-emitting diode all has normal trouble free service electric current.Charge-discharge control circuit (CT) is basic identical with the circuit theory of common emergent identification lamp, and DC converter (DC/DC) circuit is of a great variety especially, and major part here can be used.To the opening, stop control and storage battery charge and discharge control is all realized than being easier to of DC converter circuit, and the method that realizes is a lot, can design voluntarily according to concrete performance requirement.
