Abstract
Disclosed is a power supply system special for safe low-voltage LED lighting. The power supply system is characterized in that in a circuit, an external power source, a voltage transforming device and a storage battery are sequentially connected, power generated by solar energy or mains supply is converted into direct current to be stored in the storage battery, the storage battery uniformly supplies power for an LED lighting lamp by means of safe low-voltage direct current under 36V, material consumption and power consumption of the LED lamp can be saved, safety factors of lighting use and maintenance can be improved, and a user can use LED lighting under the condition of blackout.
Description
Technical field
The present invention relates to field of power management, relate in particular to a kind of electric power system that safety low-pressure LED illumination is used of specializing in.
Background technology
Since Edison invented incandescent lamps in 1879, lighting field has successively experienced incandescent lamp, fluorescent lamp and HID(high intensity discharge) 3 important developing stage of lamp, in recent years, the rise of LED lamp, cause technological revolution at lighting field rapidly, started the green illumination epoch of taking as the leading factor with semiconductor lighting.Present most LED illuminating product, its core component---LED luminous element only adopts the following safety low-pressure direct current supply of 36V basically, yet in order to adapt to the needs of household office 220V electricity consumption, each LED illuminating product is all integrated interchange conversion element is converted to direct current below 36V with the alternating current with 220V or 380V.The waste that this has not only caused on LED lamp making material more makes the caloric value of lamp body increase, and has affected the life-span of LED luminous element.Therefore, some occur on the market at present and be not with interchange conversion element LED lamp body (the following safety low-pressure LED of 36V lamp), but necessary supporting power supply adaptor when this class lamp body uses on alternating current, thereby only be used in motor vehicle illumination, flashlight and some laboratories are showed, greatly limited the application of the better LED lamp body of such quality.
Summary of the invention
To exchange conversion element LED lamp body and be used widely in household office commercial lighting field in order to promote not to be with, save the illumination cost of LED, the invention provides a kind of electric power system that safety low-pressure LED lamp uses of specializing in, this electric power system can not only be powered to safety low-pressure LED lamp in the mode of material-saving economize on electricity, and can make the user in the situation that the LED illumination is used in outage.
The technical solution adopted for the present invention to solve the technical problems is: take at the family as unit, the unified transformation of carrying out is processed, and changes backward charge in batteries, and indoor all LED lamps are by the unified power supply of storage battery of the following safety low-pressure of 36V.The concrete operations scheme is, before external power supply enters into the family, first through the potential device conversion, external power supply is converted to the direct current of 36V low pressure, with to charge in batteries, then with winding displacement, the direct current of the following safety low-pressure of 36V is transferred to the LED lamp body by the storage battery unification.
Described external power supply can be the solar power generation of different voltages, can be also civil power (alternating current of 220V or 380V).Be mainly solar power generation, if when there is no solar power system or solar power generation deficiency, can automatically switch to mains-supplied.Switch required signal and sent by storage battery, namely when storage battery quantity not sufficient 30%, will send switching signal to diverter switch.
Described storage battery is made of pole plate, dividing plate, electrolyte, housing, and input voltage is 36V, and output voltage is 12V, 24V or 36V, can be customized by the design parameter of LED lamp.
The invention has the beneficial effects as follows: the theory that has proposed the following safety low-pressure LED illumination of 36V, for the alternating current of LED illuminating lamp cancellation at present conversion element provides condition, save material consumption and the power consumption of LED lamp, can improve simultaneously the coefficient of safety of illumination O﹠M, can not bring electric shock hidden danger, and can make the user in the situation that the LED illumination is used in outage.
Description of drawings
Below in conjunction with accompanying drawing and embodiment, the present invention is done a progressive explanation.
Fig. 1 is the special-purpose electric power system structural representation of safety low-pressure LED illumination.
1 external power supply in figure, 2 potential devices, 3 common lines, 4 storage batterys, 5 little core winding displacement circuits, 6 switching signal ultramagnifiers, 7 solar cells, 8 civil powers, 9 automatic switches.
