Description

Novel fast starting Metal halogen lamp electric appliance box

Affiliated technical field:

The utility model relates to a kind of electric appliance box, relates in particular to a kind of novel fast starting Metal halogen lamp electric appliance box.

Background technology:

The Metal halogen lamp ballast that is equipped with in it of the Metal halogen lamp electric appliance box of Shi Yonging generally adopts electric ballast in the market, has high frequency and pollutes, and have harmonic problem, thereby fluorescent tube is shorter useful life.

Summary of the invention:

The purpose of this utility model is to provide a kind of ballast in it to have to light fast and does not have harmonic problem, anti-interference strong novel fast starting Metal halogen lamp electric appliance box.

The purpose of this utility model is to realize like this, described novel fast starting Metal halogen lamp electric appliance box, comprise fluorescent tube and inductance coil, its design feature is that external power one end is by protective tube one Lu Jingyi resistance, the circuit of electric capacity parallel connection is linked the external power other end, its another road connects inductance coil, the tunnel normally closed point through two series connection is connected on filament one end of fluorescent tube behind the temperature safety tube, the filament other end of fluorescent tube is linked the external power other end, another road connects the normal end of making war behind temperature safety tube, and the other end of often making war connects transformer through bidirectional diode, inductance, second resistance, the 3rd resistance, receive the external power other end behind the 4th resistance; Transformer secondary output coil and on the normally closed point of two series connection; On the two ends of second resistance, the 3rd resistance of series connection, the 4th resistance and be connected to the 3rd electric capacity; On the transformer, bidirectional diode, inductance two ends of series connection and be connected to second electric capacity.

The utlity model has following characteristics: 1) the utlity model has energy-saving and environmental protection, no harmonic problem; 2) have the fast starting function, it has prolonged fluorescent tube useful life, has permanent power functions; 3) behind tube starting, circuits for triggering are disconnected fully, have guaranteed the reliable and stable of circuits for triggering, and are not fragile; 4) owing to adopt lc circuit, Metal halogen lamp ballast self power consumption in the electric appliance box reduces greatly, has antijamming capability simultaneously; 5) it is low to have a cost, characteristics such as ballast is safe and reliable, and the life-span is long, and volume is little.

Description of drawings:

Fig. 1 is a circuit diagram of the present utility model.

Among the figure: inductance coil L1, inductance L 2, protective tube A1, temperature safety tube A2, the K1 of often making war, normally closed some K2, K3, the filament one end A of fluorescent tube, the filament other end B of fluorescent tube, transformer N1, transformer secondary output coil N2, bidirectional diode D, resistance R 1, second resistance R, 2, the three resistance R, 3, the four resistance R 4, capacitor C 1, the second capacitor C 2, the three capacitor C 3.

Embodiment:

Below in conjunction with drawings and Examples structure of the present utility model and operation principle and the course of work are elaborated:

As shown in Figure 1, the utility model comprises fluorescent tube and inductance coil L1, its design feature is that external power one end is by protective tube A1 one Lu Jingyi resistance R 1, the circuit of capacitor C 1 parallel connection is linked the external power other end, its another road connects inductance coil L1, one tunnel normally closed some K2 behind the temperature safety tube A2 through two series connection, K3 is connected on the filament one end A of fluorescent tube, the filament other end B of fluorescent tube links the external power other end, another road connects normal battle of K1 one end behind temperature safety tube A2, and the K1 other end of often making war connects transformer N1 through bidirectional diode D, inductance L 2, second resistance R 2, the 3rd resistance R 3, receive the external power other end after the 4th resistance R 4; Transformer secondary output coil N2 and on normally closed some K2, K3 of two series connection; On the two ends of second resistance R 2, the 3rd resistance R 3 of series connection, the 4th resistance R 4 and be connected to the 3rd capacitor C 3; On transformer N1, bidirectional diode D, inductance L 2 two ends of series connection and be connected to second capacitor C 2.Above-mentioned components and parts and connection are to be contained in work in the existing electric appliance box.

Operation principle is: when source current is given inductance coil L1 by protective tube A1, give capacitor C 1 charging simultaneously, resistance R 1 is a discharge resistance.(capacitor C 1 also can be connected with inductance coil L1 series system).Electric current is given second capacitor C 2, three capacitor C 3 chargings through K2, K3 and the transformer secondary output coil N2 that temperature safety tube A2 flows through two series connection at normally closed, electric current makes bidirectional diode D conducting through inductance L 2, transformer N1 produces electromotive force, and secondary coil N2 produces the high voltage supply fluorescent tube that sets out lights tube starting.

The tube starting after-current is given lamp tube power supply operate as normal through protective tube A1, inductance coil L1, temperature safety tube A2, K2, K3 at normally closed, and capacitor C 1 discharges and recharges, and makes building-out capacitor and improves power factor (PF)).Because K1 is normal battle, so after the fluorescent tube normal ignition, circuits for triggering will quit work.
