Description
The utility model belongs to illumination emergency lamp field.
For satisfying the emergent needs of illumination, occur various types of emergency lights, but all do not had energy-conservation device basically, need big electric current during startup, and still continue to use the electric current of this grade during illumination, it is more therefore to consume electric energy; Owing to the fluctuation of current/voltage, light pipe turns black very easily too early simultaneously, causes light pipe short useful life.
The purpose of this utility model provides a kind of adjustable power, consumed power is low and illumination intensity is constant substantially, light pipe useful life the emergency light of characteristics such as length, low cost of manufacture.
The utility model is realized its purpose as follows: the circuit that storage battery E and filter capacitor C1 and the energy saver, silicon controlled current-limiting resistance R4 and the C2 that are made up of potentiometer R2, R3 connect is in parallel; Have the anode A of controllable silicon SCR to join between the emitter of the negative pole of capacitor C 2 and triode BG1, BG2, the gate pole G of SCR is connected on the line between the positive pole of resistance R 4 and capacitor C 2.Negative electrode K connects the winding L 2 of pulse transformer B2.With double-triode valve output, iron core adopts straight bar magnet, coil L1 and around two the end of a thread of two lines and the contact b of K switch 1 join, again two-wire is rewound on bar magnet (and around), two tail ends connect triode BG1, BG2 collector electrode respectively; Coil L2 and around the end of a thread of two lines link to each other with BG1, BG2 base stage respectively, the two-wire tail end contact 5 after back-roll on the bar magnet again links with the negative electrode of controllable silicon SCR again.
Energy-conservation emergency light of the present utility model has utilized blocking oscillator to change power within the specific limits and constant substantially characteristic of power output and triode are operated in and adjust electric current in the range of linearity and make it be operated in different working points but the characteristic that different frequency signals obtained identical amplification, change the constant-resistance circuit of routine into resistance adjustable circuit, make the electric current of working during the illumination less than starting current, reach purpose of energy saving; Owing to controlled normal and improper light pipe the when luminous phenomenon of turning black too early, prolonged the light pipe life-span again.And the utility model luminous intensity is adjustable, and element is few, and is simple in structure, makes easily, and is with low cost, is suitable for to produce in enormous quantities and sells, and also is beneficial to self-control.Compare with domestic and international similar emergency light, the power supply effective rate of utilization can improve more than 20%.
Embodiment further specifies the utility model below in conjunction with accompanying drawing:
Fig. 1 is the circuit diagram of the energy-conservation emergency light of the utility model.
The storage battery E that charging circuit has power transformer B1, rectifier diode D, indicator light X and current-limiting resistance R1 thereof and can charge repeatedly and use, lighting circuit is by filter capacitor C1, by adjustable potentiometer R2, energy saver, controllable silicon SCR, triode BG1, BG2 and pulse transformer B2 that R3 forms, and the gate pole G of SCR is connected on the line between the positive pole of the current-limiting resistance R4 of SCR and vibration and coupling capacitance C2; Negative electrode K meets pulse transformer coil L2, and anode A is connected on the line between the negative pole of triode and C2.In the emergency light of routine, generally only use a triode, but in order to strengthen power output under the same conditions, impel light pipe luminous fast, two triodes of emergency light of the present utility model, for making two-tube work balance, also in order to simplify manufacture craft, the utility model has adopted straight clavate magnetic core, the coil winding adopts strict mode: allow earlier coil L1 and around two the end of a thread of two lines and the b point of K switch 1 join, after two-wire is rewound on bar magnet (and around), two-wire two tail ends connect the collector electrode of triode BG1, BG2 respectively; Pitch of the laps L2 and around two terminations of two lines join with the base stage of BG1 and BG2 respectively, the tail end of two-wire after back-roll on the bar magnet is connected to a little 5, joins with the SCR negative electrode.The L3 coil can adopt suitable around also rewinding.
When using emergency light of the present utility model, 1 dozen of K switch is charging to a, beats to b and be illumination.After light pipe is fully luminous, scalable R2 suitably strengthens resistance, reduce electric current, because the light pipe illuminating circuit of emergency light is exactly a blocking oscillator, and blocking oscillator is when changing power within the specific limits, the oscillator power output roughly remains unchanged, and promptly this moment, light pipe still sent suitable substantially light, has therefore realized saves energy under the essentially identical situation of illumination lumen.If luminous flux is strengthened, can suitably be turned down resistance R 2.Owing to be equipped with filter capacitor C1 in the circuit, under normal luminance, the fluctuation of current/voltage when having reduced circuit working, to eliminate the abruptness of power output, preventing that light pipe is normal turns black when luminous too early; Again because controllable silicon SCR control has been arranged, when light pipe takes place undesiredly when luminous, BG1, BG2 emitter electromotive force are low than base electrode all the time, and light pipe can only send the low light level or not luminous, avoid the too early generation of the local rubescent blackening phenomena of light pipe, prolonged the useful life of light pipe.The utility model has also adopted two triodes to strengthen power output, to quicken the luminous fast of light pipe, has also taked the way of the straight bar magnet of the reverse winding of coil L1, L2, makes two plumbers make balance and simplified manufacturing technique.Because potentiometer R3 takes the scalable potentiometer, can be luminous by the lamp of regulating various different capacities such as 4W, 6W that its resistance value realizes same circuit, 8W, 15W, 20W, enlarged the scope of application of circuit.
Use circuit of the present utility model also can make the desk lamp form and make desk lamp usefulness, can also be while charging when the lamp use.
Below propose the reference value of some main element parameters: E6V, 4Ah~10Ah storage battery R1 0.5~1K Ω R2 1~5K Ω R3 0.47-5K Ω R4 30~100 Ω C1 1000~2000 μ f C2 0.1~1 μ f SCR 1~3A BG1, BG2 and can use 3AD30, the long 3~4cm of 3DD1A 3DD1B 3DD1C 3DD15A 3DD15D bar magnet, Φ=1c,mL1 36 * 2 circles, line footpath Φ=0.35~0.6cm; L2 18 * 2 circles, line footpath Φ=0.25~0.35mm; L3 350~560 circles, Φ=0.2~0.25mm
