Description
Technical field
The utility model belongs to illumination emergency lamp field.
Background technology
The emergency lamp industry development is very fast, and domestic and international market power has many types at the high-power full-automatic energy-saving emergency light of 20～40W at present, but their circuit roughly has two partly: automatic charge and discharge circuit.Before circuit is common two: anti-overcharge device full-wave rectification, no anti-overcharge device halfwave rectifier automatic charger are arranged.The back is planted and is not made it simpler and easy because of there being anti-overcharge device, and a lot of light fixtures adopt, but ubiquitous problem is to adopt too high charging voltage, and storage battery is overcharged and lifetime.Automatic discharge circuit not level to be that output stage is common also have two kinds: output is recommended in the LC vibration, the self-excitation multifrequency is vibrated and recommended the resonance output circuit.Two kinds of circuit are all energy-conservation, but energy saver, power adjustment apparatus, thermionic emission device are manually adjusted, had to the energy-conservation need of preceding kind, and light pipe is luminous at every turn, and filament is all wanted preheating, belong to the thermionic emission circuit.Back circuit energy automatic energy saving does not have above-mentioned relative assembly, belongs to the cold electron emission circuit.This circuit working gets up, and temperature is lower, illustrates that storage battery output energy level major part becomes the luminous energy of light pipe.Thereby not only simple and easy, but also energy-conservation, adopted by a lot of light fixtures.But ubiquitous defective is: to the light pipe of different capacity, adopt and but adopt a set of pieces inequality with a kind of circuit, this is very irrational, brings many inconvenience only can for production, use, maintenance.
I former " high-power full-automatic energy-saving emergency light " (patent No. is 99258700 χ), belong to no anti-overcharge device halfwave rectifier, the LC push-pull output circuit that vibrates, also adopted higher charging voltage.
Summary of the invention
The utility model purpose provide a kind of power do not have anti-overcharge device at 20～40W but can not overcharge, the storage battery life-span is long, circuit and identical, simple and easy, energy-conservation, full-automatic, the safe and reliable high-power emergency light of element.
For reaching above-mentioned purpose, need overcome or solve two technical problems:
One, design, make no an anti-overcharge device but can not overcharge, halfwave rectifier automatic charger that the storage battery life-span is long, central key problem in technology is suitable charging voltage of selection.Perhaps the someone thinks, to the 12V storage battery, for fine charging, charging voltage should be more than 12V, and that is incorrect.Theoretical and experiment showed, emergency light at round-the-clock 24 o'clock to the 12V storage battery of awaiting orders, be more suitable with the 12V voltage charging.We tests with 12V homemade new storage battery " multiple China ", allow it be charged to rated voltage 12V (being full of) back and discharge, and the homemade light pipe of drive 40W is luminous, the most just light 3.5 hours, and after 3 years, though storage battery has natural aging, also bright 2 more than hour.Otherwise, use greater than 12V such as 14V and charge, under equal conditions, only to go through 1 year, fluorescent lifetime is reduced to 1 rapidly below hour, and this is a difference how significantly, illustrates with the 12V voltage charging to have very big economic benefit.Why can be such? reason is after being full of electricity, and the 0.2A electric current of still having an appointment flows through storage battery, and this electric current is emitted heat in the inner chemical substance of storage battery, makes these materials keep active for a long time and prolongs its life-span greatly.
Two, to 20～40W light pipe, design and make the vibration of the identical self-excitation multifrequency of a circuit and element and recommend the resonance output circuit, enable the output of automatic energy saving and automatic power adjustment, correspondingly make above-mentioned three kinds of power light pipes powerful luminous.Central key problem in technology is to be what correctly selects this set of pieces when circuit is identical.Theoretical and experiment showed, that this set of pieces is determined by above-mentioned vibration output circuit characteristic.Need know that self-excitation multifrequency frequency of oscillation is very wide, within the specific limits, resonance circuit is appointed and is got a set of pieces, and its resonance frequency all can drop within its very wide frequency range.But we necessarily get a set of pieces, make self-excitation multifrequency oscillation circuit and resonance circuit all produce strong vibration and make the 40W light pipe luminous strong, when putting 20W and 30W, circuit also makes them luminous strong with regard to the output of energy automatic power adjustment is corresponding, then do not become conversely, make the 20W light pipe luminous strong earlier as the element of selecting, when putting 30W, during 40W, just can only export the luminous corresponding power of 20W light pipe, make their luminous dimnesses or not luminous, this just causes the above-mentioned different capacity light pipe same circuits of saying, the defective of different elements, produce this as a result main cause be not to be familiar with the result that related characteristics caused of above-mentioned oscillator.
Though compare with the same circuits different elements with same circuits and element, to the equal-wattage light pipe, it is roughly the same to consume energy, and the former brings a lot of benefits to emergency light production, use, maintenance, obviously, has very big economic benefit.
In sum, the technical solution of the utility model is as follows: in charging circuit, and electric current B
1Secondary voltage is 12V, by there being anti-overcharge device half-wave rectifying circuit storage battery E is not charged automatically.During charging and the secondary resistance R that is parallel with

By on know that the utility model is the product of the theoretical and practice of former utility model, also be simultaneously the product that current design both at home and abroad, production, utilizing high power emergency light are summarized.It not only keeps the reasonable part of former utility model as preventing putting device, operating switch K
1, lamp socket switch K
2And the relevant part of automatic circuit, also increase no anti-overcharge device but can not overcharge, the storage battery life-span is long, to different capacity employing same circuits and two characteristics that have an economic benefit very much of element, this is that former utility model and present domestic and international market like product do not have.
A kind of high-power full-automatic energy-saving emergency light, because it is simple and easy, energy-conservation, full-automatic, safe and reliable, still vast place such as hospital does not need white light and the big specialty of irradiated area lamp, is good fire-fighting lamp simultaneously yet, as long as light pipe that glows of installation has just become.In addition, the circuit output stage is placed in the lamp holder, can becomes mobile subscriber's emergency light, also can be made into power less than the 20W emergency light, the headlight lampet is expected to become domestic and international market a new generation emergency light key product.In addition, what any also will be described is, the very convenient buying of system lamp raw material, and tools are simple and easy, and cost is low, but the price height, if investment and production necessarily has good prospect.
