Abstract
The utility model relates to a combined fluorescent lamp ballast which is composed of an inductance device and an electronic device. The utility model comprises a transformer 1, a fluorescent lamp tube 7, a heater winding 4, a bidirectional controlled silicon 5 and a resistor 6. The utility model has the advantages that a bimetallic breaker is not needed; the circuit is not provided with contacts; the voltage borne by the electronic device is lower than the voltage borne by the electronic device in the electronic ballast, and the utility model can not be damaged easily. Therefore, the utility model also has the advantages of reliable work, low energy consumption, light weight, small size, less material consumption and low cost.
Description
The utility model belongs to the control apparatus of fluorescent lamp technical field.
Existing fluorescent lamp controllers has inductance type and electronic type two classes.The inductance type ballast reliable operation do not produce radio interference, but weight is bigger, and consumptive material is many, and energy loss is big, bimetal release easy break-down wherein, and cost is higher.The electronic control device volume is little, and is in light weight, and energy loss is little, therefore is widely used in recent years, but because its components and parts are operated under high voltage, the big current condition, damage easily, and produce high order harmonic component, and power supply and radio wave are all had interference effect.
The hybrid fluorescent lamp ballast that the purpose of this utility model is to provide reliable operation, the volume weight of a kind of electronic device and inductance component dual-purpose little, energy loss is low.
The utility model comprises transformer 1, Filament Winding 4, controllable silicon 5, resistance 6, fluorescent tube 7.Fig. 1 is its structure chart.Now as follows to its structure and connection description in conjunction with Fig. 1: the elementary winding of transformer 12 inserts 220 volts of alternating voltages, and two Filament Winding 4 are connected with secondary winding 3 and on same iron core.The tap of secondary winding 3 and two Filament Winding junctions is connected with an end of two filaments 8 of fluorescent tube 7 respectively.Filament Winding 4 is also connected with controllable silicon 5 and filament 8, forms a loop.Resistance 6 is connected in parallel between the anode and the control utmost point of controllable silicon 5.Controllable silicon 5 can adopt bidirectional triode thyristor, also can adopt one-way SCR.
Behind transformer 1 input ac voltage, secondary winding 3 promptly produces induced potential, is added between two filaments 8 of fluorescent tube 7.Filament Winding 4 also produces induced potential, forms the loop by resistance 6, forms voltage drop by electric current thereon, so make controllable silicon 5 conductings, the electric current of Filament Winding 4 makes filament 8 heating promptly by controllable silicon 5 and filament 8.When filament 8 was heated to uniform temperature, fluorescent tube 7 interior gases promptly produced ionization and light.After this, inferior group of winding 3 and Filament Winding 4 voltages reduce, and controllable silicon 5 stop conductings, fluorescent tube 7 are kept by the low-voltage of secondary winding 3 and lighted.
The utility model has the advantages that to need not bimetal release, contactless in the circuit, easy break-down not; The voltage that electronic device bore in the mixed ballast is low than the voltage that electronic device in the electronic ballast bears, and is not fragile; Consumptive material is few, and energy consumption is low, and weight and volume all reduce, and cost is low, reliable operation.
