One electronic ballast can start one to four florescent lamps which are connected in series. The utility model is especially suitable for the illumination of the factory shops with rotating machinery.
Description
The utility model belongs to the efficient no stroboflash fluorescent lamp of electronic ballast.
Present employed fluorescent lamp mostly is inductance ballast, and power factor is low, and Inductive ballast power consumption is big, and the efficient of fluorescent lamp is reduced, and because of the stroboscopic of fluorescent lamp influence people's eyesight, and radio, TV are produced interference.
For these reasons, the purpose of this utility model is to substitute Inductive ballast with electric ballast, improve power factor and efficient, add bridge rectifier filter circuit, make it under dc state, to work, eliminate the stroboscopic of fluorescent lamp and, also avoided the high frequency radio interference problem that high-frequency electronic ballast brought the interference of radio, TV.
Basic comprising of the present utility model is to adopt the multiplication of voltage bridge rectifier filter circuit as electric ballast, in order to start fluorescent lamp, and after startup, give current limliting with incandescent lamp, can have above-mentioned advantage, the life-span of fluorescent lamp is improved greatly, and 80% above useless fluorescent tube need only air tight, have electron emissivity all can luminously to use.
Principle according to the multiplication of voltage bridge rectifier, utilize the diode forward conducting, the characteristic of oppositely ending to one group of electric capacity charging, and is summed into high direct voltage, the voltage at fluorescent tube two ends is elevated to about 620 volts or 930 volts, after the fluorescent lamp conducting, terminal voltage drops to normal working voltage immediately, when the incandescent lamp in the electric ballast plays the ballast effect as resistance, again can be normally luminous, make whole illuminant color soft and true to nature.

9, but cost is increased, and inadvisable.By experiment, the electric ballast of one three multiplication of voltage can start 2-4 root fluorescent tube, as two 40 watts or two 30 watts or four fluorescent tubes below 20 watts in alternating voltage is 220 volts power frequency supply.In alternating voltage is 110 volts power frequency supply, can start 1～2 fluorescent tube below 20 watts.
Above-mentioned fluorescent switch DK is double-pole three throw switch, and its effect is to change fluorescent tube DG polarity and switch fluorescent lamp.Because the phenomenon of anodal deepening can appear in the fluorescent lamp of working under dc state, continuous operation after tens hours, luminous efficiency is reduced, solution in the past be fluorescent lamp transfer one following, pretty troublesome.Utilize switch DK to solve this problem easily now, have switching characteristic simultaneously concurrently.What be worth proposition especially is, because an electric ballast can start many fluorescent lamps, thereby cost is reduced, economize on electricity significantly, use two 12 watts fluorescent lamp and one 10 watts incandescent lamp in family, its gross power be 34 watts just can be simultaneously to 3 room illumination.Some are had the factory floor of rotating machinery, use both safety of the efficient no stroboflash fluorescent lamp of electronic ballast, economize on electricity again is for new way has been opened up in the use of fluorescent lamp.
The utility model also has following advantage and economic benefit:
(1) efficient height, economize on electricity are significantly. An electric ballast can start 2～4 fluorescent lamps that are in series, and compares with Inductive ballast: replaced 2～4 Inductive ballasts, and about 8 watts of Inductive ballast power consumptions so just can be economized on electricity about 16 watts～32 watts; ZD has replaced current-limiting resistance with incandescent lamp, and the utilization rate of power supply has been improved, COS φ ≈ 1; Under equal illumination, power consumption is littler.
(2) volume is little, and is in light weight, and cost is low, owing to adopted capacity big, volume is little, and electrochemical capacitor in light weight, that cost is low makes the volume of whole electric ballast little of a box cigarette, and weight is about 150 grams.
(3) adjustable brightness as long as change the incandescent lamp ZD of different capacity, just can make the brightness of same group of fluorescent lamp change thereupon; As long as change the incandescent lamp ZD of different voltages and power, same electric ballast can start the fluorescent lamp of different capacity, to satisfy the needs of various illumination.
(4) start soon, the life-span is long.Just as driving incandescent lamp, at low temperature, still can start immediately under the low pressure, the electric current during startup rises to operating current gradually by little, thereby has prolonged the life-span of fluorescent lamp DG and incandescent lamp ZD.
(5) remarkable in economical benefits.Generally adopt the utility model to save a large amount of copper cash, silicon steel sheet and fluorescent lamp for country.
