Abstract
The electromagnetic ballast for quickly starting fluorescent lamp is composed of ballast, commutating diode, voltage-stabilizing tube and starter, and features that the coil of electromagnetic starter is serially connected to the working circuits of ballast and lamp tube, and the normally closed contact of starter is connected to the lamp filaments at both ends of lamp tube for heating and starting lamp filaments.
Description
The utility model relates to a kind of fluorescent lamp electromagnetic type fast starting ballast.
Daylight lamp glow starting of the prior art, ballast mainly contain two kinds of working forms, and a kind of is traditional iron core ballast ballast, neon bulb starter build-up of luminance, and another kind is an electric ballast.
In traditional daylight lamp circuit, the useful life of neon bulb starter is shorter, so its connection is to adopt Mechanical Contact, just with transposing, because Mechanical Contact, time one is long, just easily loosening loose contact adds that the life-span of itself is not long yet, so failure rate is very high, on startability, because the bimetal leaf in the neon bulb will heat the back starter earlier, it is also long to turn round and look at general starting time, also has the neon bulb starter to be easy to the production short circuit, long-time short circuit work is easy to make that ballast is overheated burns out, and this also is the one of the main reasons that ballast damages.
Another kind of electric ballast, he is a kind of completely new product that designs along with the development of semiconductor device in recent years, it has the service behaviour of good starting performance and low pressure, and also have volume little, advantage such as in light weight, but shortcoming is also very obvious, first, poor stability, since during daylight lamp glow starting moment operating voltage more than 700V, sometimes even more than 1000V, so the power tube of electric ballast is very easy to damage, other components and parts are because the high electric current of operating voltage is big, factors such as the element anode-cathode distance is short, also be easy to discharge each other and punch through damage, the operation element life-span is also very limited in this case for a long time, if, run into moist environment, just easier breaking down.The second, brightness is not high, and the operating frequency of electric ballast is higher, makes operating current that " collection skin " phenomenon be arranged, and makes lamp luminescence efficient not good, and brightness is not high.The 3rd, the price height owing to use the high voltage bearing transistor device of big electric current, can't descend the cost of electric ballast, so product price is also than higher.
The utility model is to adopt iron core ballast and the work of electromagnetic type starter, on starting speed, the electromagnetic type starter can be at 0.5 second internal starting during at 180V-220V when voltage, when voltage during in the 150V left and right sides, also can be in 2 seconds starter smoothly because the machine work life-span of electromagnetic type starter is 10
6More than inferior, appliance contact is also 10
5More than inferior, working every day 25 times, the most conservative life-span is also more than 10 years, thereby can reach long-life work.
Formation of the present utility model: by ballast L, commutation diode D
1-D
4Voltage-stabiliser tube WG and electromagnetic starter coil J, normally-closed contact K
JForm with fluorescent tube T.
Advantages such as compared with the prior art, the utlity model has working stability, starter is fast, and the life-span is long during owing to electromagnetic type starter and ballast manufacturing, have been made one, so have only two groups of tube lines and one group of power line, it is very convenient that the user is installed and used.
Accompanying drawing is arrangement works figure of the present utility model.
Embodiment of the present utility model: as shown in the figure: when the energized of AA ' two ends, electric current brings out from A and sends out, by ballast L, fluorescent tube a end filament, starter normally-closed contact K
JArrive b end filament, by commutation diode D
1-D
4, voltage-stabiliser tube WG and initiator coil J arrive A ' form and start the loop, in starting the loop, the filament at fluorescent tube a, b two ends obtains heating, there is stable operating voltage at initiator coil J two ends.After initiator coil J has operating voltage, normally-closed contact K
JOpen circuit produces the high pressure back-emf and hits logical fluorescent tube when ballast L opens a way suddenly in the closed-loop path, the electric current that normally-closed contact is flow through changes its course and flows through from fluorescent tube, makes initiator coil continue to obtain the operating voltage adhesive, and normally-closed contact continues to open and enters normal operating conditions.
When fluorescent tube is not hit when logical, the initiator coil decompression, the normally-closed contact closure starts so enter for the second time, start for the third time, until hit logical till, enter operate as normal.
Claims (3)
1. a fluorescent lamp electromagnetic type fast starting ballast is made up of iron core ballast, commutation diode, voltage-stabiliser tube, initiator coil, normally-closed contact, and it is characterized in that: initiator coil J is at commutation diode D
1-D
4Effect under, be serially connected in the work loop of ballast L and fluorescent tube, the starter normally-closed contact connects the lamp tube ends filament, makes the fluorescent tube can heat filament before work, disconnects moment can hit logical fluorescent tube, can disconnect the filament heating circuit after the lamp works.
2. electromagnetic type fast starting ballast according to claim 1 is characterized in that the work of initiator coil J, provides the loop by normally-closed contact before starter, is that electric pipe provides the loop behind starter.
3. electromagnetic type fast starting ballast according to claim 1 is characterized in that the operating voltage of initiator coil J keeps stable by voltage-stabiliser tube WG.
