Abstract

The utility model relates to an intelligent type ballast system which enables a light tube to work with higher voltage and low voltage, mainly comprising an intelligent controller N and a ballast ZL-d with multiple taps. The intelligent controller N compares and calculates the detected voltage / current of the power supply and the voltage / current of the light tube with the normal voltage / current, and outputs a regulating and controlling signal to control a relay J to act, and thus one tap of the ballast ZL-d with multiple taps (the tap matched with the voltage of the light tube) is connected into a circuit and consequently the light tube can work normally and the service life is prolonged. The intelligent controller N is also provided with a timer which enable the intelligent controller N to output the regulate and control signal to control the relay J to act and conduct power switching in setting time (for example after 12 pm), and thus the light tube can work in low power and consequently the purpose of use cost saving is achieved.

Description

Intelligent Bollast system

Technical field

The utility model relates to a kind of intelligent Bollast system, relates to a kind of intelligent Bollast system in the lighting device that use in places such as various buildings, square, road specifically.

Background technology

Along with expanding economy, various factories, building, square, road etc. are built more and more, and these places all will be used various light fixtures and light source and thrown light on, and the light source of employing mainly is gaseous discharge lamps such as various fluorescent lamps, high-pressure sodium lamp, metal-halide lamp.Gaseous discharge lamp has negative voltage-current characteristic, and promptly when lamp current increased, modulating voltage was not to raise but decline, so till under constant voltage, will causing the unconfined increase of lamp current certain part in lamp or circuit to be burnt by overcurrent.When so gaseous discharge lamp is received in the electrical network separately, its work is unsettled, till it will cause electric current in the circuit unrestrictedly to increase certain part in lamp or circuit being burnt by overcurrent, therefore under constant voltage in order to limit lamp current, the assurance lamp can be worked normally, the electric elements with positive voltage-current characteristic of must connecting one come this negative voltage-current characteristic of balance, and what adopt at present is electric ballast and Inductive ballast.Because the little employing electric ballast of power of various fluorescent lamps is some more slightly, and high intensity discharge lamps such as high-pressure sodium lamp, metal-halide lamp are because power is big, the also big electronic devices and components that puncture easily of electric current in the circuit, so what use basically is Inductive ballast, also to installs trigger additional in the circuit of use Inductive ballast and just can light fluorescent tube.

We know that the scope of the supply voltage that electric ballast adapts to than broad, can both make lamp light and provide stable line current in the voltage range of 160-250V even in the wideer voltage range, make the fluorescent tube operate as normal.Because it is narrow that the different induction ballast of design principle and manufacturing technology adapts to the scope of supply voltage, generally can only fluorescent tube be worked normally (has the scope of many producers littler, can only in the electrical network domain of walker of national regulation, make lamp works), line current increases when supply voltage is higher, the long-time overpower work of fluorescent tube, the life-span of fluorescent tube is shortened, when supply voltage is higher than 242V, because line current increases, the ability to bear that has surpassed fluorescent tube, cause framework temperature distortion in the fluorescent tube (as high-pressure sodium lamp, metal-halide lamp), the very big power of generation makes the glass fragmentation of fluorescent tube, thereby cause that lamp tube air leaking damages cisco unity malfunction, when supply voltage is on the low side when being lower than 180V, fluorescent tube can not start work again.Transform the back line voltage through " golden net engineering " and on the low sidely become generally higherly from general, cause the lost of life of fluorescent tube, the serious fluorescent tube that makes damages in a short period of time.Also have a situation be exactly present illuminating engineering be to adopt dedicated transformer independence winding displacement mostly, just high near voltage on the light fixture of transformer, the ability to bear that has surpassed fluorescent tube, fluorescent tube damage or life-span are shortened, power on away from the light fixture of transformer and to force down, fluorescent tube can not be operated at full capacity, and the luminous flux that sends is just few, and the illumination on road surface is just little.Owing to the problem of funds, a transformer will use for many light fixtures sometimes, surpasses its load capacity again, lower away from voltage on the light fixture of transformer, fluorescent tube can not start work or can start work at the beginning, uses after two, three months, just can not start work.

Surpass 12 points at night in the city, the pedestrian of the street, vehicle are just seldom, it is that brightness value can reduce that illumination on the road does not need very bright, cost for the electricity consumption that saves lighting, people adopt the mode that concentrated or half centralized control room are set to come switch lamp, with open half lamp, the interval mode of lighting a lamp of half lamp that goes out saves lighting the electricity charge, except that having increased a large amount of costs, also make like this road the preceding paragraph bright one section dark or bright one side is dark on one side, driver and pedestrian feel under the weather, and particularly are easy to generate some accidents in dark place.

For electrical energy saving, it is 02279626.6 patent reaches the electric cost that saves lighting with the method for regulating the supply transformer output voltage purpose that people have also adopted the certain methods such as the patent No., but it has only timed unit, output voltage by the time switch control transformer economizes on electricity, if line voltage is higher, fluorescent tube is damaged or the lost of life, even the output voltage of transformer also may reach 230V, 210V when the time switch of 200V, 180V was closed behind the several hrs, thereby did not reach the purpose of economize on electricity.

Method is to provide stabilized voltage power supply or alternating source to fluorescent tube preferably, but stabilized voltage power supply or alternating source price are higher, and many users do not afford to do, and is also not too practical in China at present.

Summary of the invention

The purpose of this utility model is that to overcome existing voltage difference of height too big, cause fluorescent tube to damage easily, the lost of life maybe can not start the shortcoming of work, and adopt and open half lamp, the mode that half lamp both lit a lamp at interval of the going out electricity charge that save lighting, make road the preceding paragraph bright one section dark, make troubles or the present situation of accident to people, provide a kind of simple in structure, easy to use, the intelligent Bollast system that cost is low, the place that makes regulation of line voltage exceed standard can both be used intelligent cheaply Bollast system and be made the fluorescent tube operate as normal, makes to be ready can both use intelligent cheaply Bollast system by the save lighting unit of electric cost of conversion fluorescent tube power output.

Intelligent Bollast system of the present utility model is achieved (be the example explanation with the luminaire for road and street lighting, the electricity principle of other lighting is identical therewith) by following technical proposals, and the utility model is made of many tap ballast, intelligent controller etc.

The utility model charging system has following beneficial effect compared with prior art:

1. owing to adopted intelligent Bollast system, people can install intelligent Bollast system in single light fixture, make each light fixture can both regulate the impedance selection optimum Match of ballast according to the height of line voltage and modulating voltage automatically, make the fluorescent tube operate as normal.Modulating voltage can rise gradually after generally fluorescent tube used a period of time, if can make modulating voltage just remain in the suitable scope useful life of prolonging lamp tube greatly in the life cycle of fluorescent tube, a large amount of saving cost of use.

2. owing to adopted intelligent cheaply Bollast system, automatically carry out power in the time of setting (for example at night after) at 12 and switch, make the fluorescent tube low-power operation, the cost of the electricity consumption that saves lighting has also prolonged useful life of fluorescent tube, ballast simultaneously.

3. this intelligent Bollast system contracts and saves unit particularly suitable with lottery by norm to cost of use.

Many tap ballast of BX fuse ZL ballast C electric capacity A trigger D fluorescent tube J relay N intelligent controller ZL-d K1-1, K1-2, K1-3, K1-4 switch among Fig. 1, Fig. 3

Many tap ballast of ZL-d XT connects connector N intelligent controller among Fig. 4

Embodiment

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

Ballast ZL, fluorescent tube D are connected in the circuit among Fig. 1, trigger A is connected in parallel on the two ends of fluorescent tube D, and capacitor C plays the compensating circuit power factor, because it does not have the effect of adjusting, therefore fluorescent tube is very high to the requirement of input voltage, generally in 220V ± 10%V scope.

Intelligent controller is measured the voltage/current on input voltage/electric current and the fluorescent tube and is compared with normal voltage/electric current according to the program of setting among Fig. 2, makes certain tap place in circuit on many tap ballast according to the parameter situation intelligent controller N control relay J action of setting.

Many tap ballast ZL-d, fluorescent tube D are connected in the circuit among Fig. 3, and trigger A is connected in parallel on the two ends of fluorescent tube D, and capacitor C plays the compensating circuit power factor, and intelligent controller N connection in series-parallel is in circuit, and relay J is the part of intelligent controller N.

Many tap ballast ZL-d is connected with intelligent controller N by connecting connector XT among Fig. 4.

In the drawings, intelligent Bollast system mainly is made of intelligent controller N and many tap ballast ZL-d, connects connector XT and plays connection, makes things convenient for installation, maintenance and replacing.Intelligent controller N compares computing such as detected supply voltage/electric current and light tube electric voltage/electric current and exports adjustment signal with normal voltage/electric current, control relay J action makes many tap ballast ZL-d go up certain tap place in circuit, makes fluorescent tube operate as normal and life-saving thereby reach.If supply voltage is lower than 220V, then intelligent Bollast system repeat circuit J action, make the tap that is lower than standard value voltage/impedance on many tap ballast ZL-d be connected (tap that is complementary with light tube electric voltage) with circuit, particularly suitable when this can not start work for the supply voltage 180V of being lower than fluorescent tube on the low side: if supply voltage is 240V or higher, then intelligent Bollast system repeat circuit J action makes the tap that is higher than standard value voltage/impedance on many tap ballast ZL-d be connected (tap that is complementary with supply voltage) with circuit.The suggestion adjustable range is at 10V～15V, because scope is too small, manufacturing cost is too high impracticable, and the scope extention effect is relatively poor.

Timer work among the intelligent controller N simultaneously, (for example at night 12 after) intelligent controller N exports adjustment signal control relay J action carrying out power again and switches in the time of setting, make the fluorescent tube low-power operation, general cpable of lowering power about 40%, the cost of electricity consumption saves lighting, voltage/the impedance that had both increased ballast with the way that reduces the fluorescent tube power output just reduces the voltage on the electric current minimizings/fluorescent tube in the circuit, thereby makes the power output minimizing of fluorescent tube.Usually timer provides the power supply non-stop run by battery, because the problem of battery and field of employment, replacing battery inconvenience, here recommend to use after the energising the just timer of timing, set the energising back and carried out the power switching in 5 or 6 hours automatically, make the fluorescent tube low-power operation, the cost of the electricity consumption that saves lighting is proper.

Why to measure the voltage on the fluorescent tube? we know in the operation parameter of fluorescent tube light tube electric voltage, reason owing to design and manufacturing cost, light tube electric voltage can not be on a numerical value, but a scope is arranged, with NG250 is example, its light tube electric voltage is 100V ± 20V, that is to say that the power that light tube electric voltage sends for the 100V fluorescent tube is 250 watts, and this voltage work fluorescent tube down is in optimum state.It is too much that light tube electric voltage is higher than 100V, and power far surpasses 250 watts, and the luminous flux that sends is just many, and the illumination on road surface is just big, but will shorten the useful life of fluorescent tube.Modulating voltage can rise gradually after generally fluorescent tube used a period of time, and will shorten the useful life of fluorescent tube, if can make modulating voltage just remain in the suitable scope useful life of prolonging lamp tube greatly in the life cycle of fluorescent tube.It is too much that light tube electric voltage is lower than 100V, and can prolong the useful life of fluorescent tube, but power does not reach 250 watts, and the luminous flux that sends is just few, and the illumination on road surface is just little.If supply voltage is 220V, light tube electric voltage is 100V, and then intelligent Bollast system repeat circuit J is failure to actuate, and the tap that many tap ballast ZL-d goes up standard threshold voltage/impedance is connected with circuit; If supply voltage is 220V, light tube electric voltage is 80V or lower, and then intelligent Bollast system repeat circuit J action makes the tap that is lower than standard value voltage/impedance on many tap ballast ZL-d be connected (tap that is complementary with light tube electric voltage) with circuit; If supply voltage is 240V or higher, light tube electric voltage is 100V, and then intelligent Bollast system repeat circuit J action makes the tap that is higher than standard value voltage/impedance on many tap ballast ZL-d be connected (tap that is complementary with supply voltage) with circuit; Situations such as all the other supply voltages are on the low side, light tube electric voltage is higher are handled by that analogy.
