Abstract
The ballast for durable energy-saving fluorescent lamp is practically used on the fluorescent lamp lighting fitting. The utility model has the advantages of low cost, long service life, fast starting speed in low voltage and energy saving. The ballast for durable energy-saving fluorescent lamp successfully makes use of the electronic glow starter replace the traditional mechanical starter.
Description
The utility model is applied on the fluorescent lamp tool.
The traditional fluorescent lamp light fixture is made up of inductance rectifier, starter, and this ballast starts slow, and easily glimmers when starting, and can shorten the useful life of fluorescent tube like this.Another kind of is the electric ballast of main flow with the electronic component, though can address the above problem, because of its cost height, self short in life-span, in addition to the harsh requirement of some former device, and limits its usefulness.
In order to address this problem, Chinese patent HO5B41/61 proposes to replace inductance with capacitor, reducing cost and power consumption, and can produce fast starting to fluorescent tube.But in actual use, with some trouble of switch of two button light modulations on controll day, again owing under the situation of low-temp low-pressure, start some difficulty.
The purpose of this utility model is that a kind of improved long-life energy-saving fluorescent lamp ballast will be provided, and it can solve effectively and start difficulty, these problems of long-life energy-saving.
The purpose of this utility model is achieved in that to filament provides required operating current, during work, and when filament pre-heating arrives to a certain degree, by electronic starter control lamp luminescence, in case lamp luminescence, the electronic starter automatic disconnection, fluorescent tube just can descend Chang Faguang.
The utility model adds just work when starting of electronic starter owing to utilize this function of filament pre-heating, and the remaining time does not work, so this improves the useful life of self undoubtedly.Because inductance type ballast can operate as normal in order to start convenient and to adapt under the low-voltage, have to improve the operating current of fluorescent tube again, so just additionally increased the power consumption of fluorescent tube.And this ballast has adopted the electronic starting device, does not need to improve the operating current of fluorescent tube, so saved electric energy again.
The concrete structure of utility model provides embodiment by the following drawings.
Accompanying drawing is the schematic diagram according to the long-life energy-saving fluorescent lamp ballast that the utility model proposes.
Below in conjunction with detail and the working condition of accompanying drawing detailed description according to the ballast that the utility model proposes.
This ballast is by capacitor C
1Inductance L is formed series connection ballast, capacitor C
2With resistance R, trigger tube T
1With controllable silicon T
2Form electronic starter.
During work, the 220V line voltage is through capacitor C
1, enter fluorescent tube after the inductance L current limliting, capacitor C
2Form the branch hydraulic circuit with resistance R, adjust resistance R, its both end voltage is changed in 25-35V, this voltage is added in trigger tube T
1On, make its conducting, simultaneously controllable silicon T
2Also conducting, filament obtain preheating behind the electric current, because controllable silicon T
2Certain angle of flow and capacitor C are arranged
1, inductance L existence, voltage and the capacitor C of line voltage when positive and negative each half cycle
1On voltage superimposed, the fluorescent tube after the preheating adds high pressure, the very fast conducting of fluorescent tube is luminous, the fluorescent tube both end voltage descends after the conducting, causes the voltage on the resistance R to descend, as a result trigger tube T
1Do not trigger controllable silicon T
2Turn-off, fluorescent tube is just normally luminous.
Claims (3)
1, the long-life energy-saving fluorescent lamp ballast is useful on the fluorescent lamp tool, and this ballast has a capacitor C
1, inductance L and by capacitor C
2, resistance R, trigger tube T
1With controllable silicon T
2Form electronic starter, it is characterized in that capacitor C
1With inductance L series connection, capacitor C
2With resistance R series connection dividing potential drop, the electric current after the dividing potential drop is through trigger tube T
1Trigger controllable silicon T
2
2, ballast according to claim 1, its feature is got 25-35V in the partial pressure value that is the resistance two ends and is advisable.
3, according to claim 1,2 described ballasts, it is characterized in that by capacitor C
2, resistance R, trigger tube T
1With controllable silicon T
2The electronic starter of forming is in case tube starting just quits work.
