Abstract

The utility model relates to an iterated-voltage glow starting inductance light pipe bracket. The utility model is mainly composed of capacitors C and C1, a thermistor R, diodes D and D1, a resistor R1, AN inductance ballast L, etc. Because a circuit has low basal requirements on elements, the possibility that the elements are damaged does not exist, and each element of an iterated-voltage glow starter can be encapsulated together with the inductance ballast L so as to achieve the integral integration of the elements. Therefore, the installation, the maintenance and the operation of light pipes are convenient and economical when the light pipes are used, and the external appearance of the light pipes is beautiful.

Description

A kind of starter inductance light pipe support of repeatedly pressing

Technical field:

The utility model relates to a kind of starter inductance light pipe support of repeatedly pressing.

Background technology:

At present, traditional self-induction starter inductance light pipe support is topmost energy-saving illumination electrical equipment, its circuit diagram such as Fig. 1, C is the filter high frequency capacitance, during work, energized, A, B holds energising, be enclosed between the bimetal leaf contact in the contact starter DW with glass neon bubble and reach discharge voltage and mutual emitting electrons, because electronic impact, the bimetal leaf heating of contact is crooked closed, so a big electric current is arranged through Inductive ballast L, light pipe 1 two ends filament, the bimetal leaf contact is flow through, and make filament obtain preheating, closed bimetal leaf contact stops discharge because of closed, and separates in the moment of its natural cooling, cuts off the big electric current by Inductive ballast L, Inductive ballast L goes out high voltage because of the rapid self-induction of minimizing that hinders electric current, be added in light pipe 1 two ends and light light pipe 1 through power channel, light pipe 1 impedance of being lighted reduces rapidly, and the two ends pressure drop descends thereupon, the bimetal leaf contact stops discharge, light pipe 1 operate as normal.Owing to the various reasons such as packaging technology restriction of life-span property, glass and the metal of the difficulty to control of above-mentioned self-induction high pressure, machinery make filter high frequency capacitance C be easy to puncture, the bimetal leaf contact is also because of ageing failure damage easily ahead of time, use on the private jack so need be packaged together them (being commonly called as starter) on the insertion light pipe support, change when damaging inefficacy with box lunch, the not compactedness of obvious this support has influenced attractive in appearance, give to install and use again and brought very big trouble, and easy damage of starter brought influence also for the economy of light pipe support.

Summary of the invention:

The purpose of this utility model provides a kind of starter inductance light pipe support of repeatedly pressing, and it can overcome the deficiencies in the prior art.

The utility model is achieved in that it mainly is made up of parts such as capacitor C, C1, thermistor R, diode D, D1, unidirectional controllable silicon S CR1, resistance R 1, Inductive ballast L, wherein, thermistor R and diode D, diode D1 are with capacitor C 1, unidirectional controllable silicon S CR1 and after resistance R 1 is connected respectively, in parallel with capacitor C and light pipe 1 again, and then connect with Inductive ballast L, form the loop.

The utility model is because circuit is very low to the basic demand of element, the possibility that does not have component wear, can will repeatedly press each element and the Inductive ballast L of starter to be packaged together, realized the integrated integration of element, make that installation, maintenance, use when light pipe uses are more convenient more economical, outward appearance is more attractive in appearance.

Embodiment:

As shown in Figure 2, the utility model mainly is made up of parts such as capacitor C, C1, thermistor R, diode D, D1, unidirectional controllable silicon S CR1, resistance R 1, Inductive ballast L, wherein, thermistor R and diode D, diode D1 are with capacitor C 1, unidirectional controllable silicon S CR1 and after resistance R 1 is connected respectively, in parallel with capacitor C and light pipe 1 again, and then connect with Inductive ballast L, form the loop.

During work, energized, when the A of power supply end is negative power supply for positive B end, capacitor C 1 charges in the conducting of A-B direction under the approximate power supply maximum value voltage electric energy storage with diode D1, showing as the A end is negative for positive B end, when power supply changes direction, B end for positive A end for negative during from E point that zero increases to as Fig. 3, the unidirectional controllable silicon S of flowing through CR1 control electrode current increases to UE/R1 and makes unidirectional controllable silicon S CR1 triggering and conducting, the discharge voltage of capacitor C 1 is identical with the power supply supply power voltage, superposition increases after Inductive ballast L discharges along the B-A direction to unidirectional controllable silicon S CR1, because the impedance of the internal resistance of source and Inductive ballast L coil resistance can be ignored far fewer than the inductive impedance of Inductive ballast L, so capacitor C 1 discharge drops on the Inductive ballast L with the high pressure major part of the voltage U E superposition of power supply this moment, Inductive ballast L basic absorption the discharge electric energy of U ε+UE voltage store; When supply voltage increases to F point as Fig. 3, capacitor C 1 discharge off, Inductive ballast L generates the A end conversely and is negative voltage for positive B end, just in time identical with power supply supply power voltage direction and superposition increases capacitor C 1 is charged in the B-A direction through unidirectional controllable silicon S CR1, the high voltage electric energy voltage of superposition is added in light pipe 1 two ends and lights light pipe 1 through the A-B of diode D conducting direction, the impedance decline two ends pressure drop of lighting of light pipe 1 reduces, power supply transfer to once more A end for positive B end when negative, the B-A direction of unidirectional controllable silicon S CR1 is transferred to by conducting and ending, circuit quits work, and light pipe 1 is normally luminous.If certain reason causes light pipe 1 not light conducting, the direction of the high voltage U ε+UE+UF of superposition on capacitor C 1 is that the positive A of B is negative, just in time with this moment the power supply supplier of electricity to opposite, and power supply falls back to zero process from the F point, superposition work is next time carried out in electrical energy transfer telegram in reply source again.By as seen above-mentioned, the magnitude of voltage that capacitor C 1 is born U ε+UE+UF is less than three times supply voltage maximum, the magnitude of voltage that diode D1, unidirectional controllable silicon S CR1 bear U ε+UE is less than or equal to twice supply voltage maximum, and promptly basic element production technology can both satisfy this parameter request fully at present.
