Abstract
The utility model relates to a lamp tube test circuit, in particular to a protection circuit for an electrodeless lamp tube test board. The protection circuit provided by utility model aims to effectively test an electrodeless lamp tube and protect all components in the circuit, thereby avoiding the situations of component burning and influence on safety. The utility model provides the technical scheme that the protection circuit for the electrodeless lamp tube test board comprises a power switch connected with a power supply and a ballast connected with the electrodeless lamp tube; the protection circuit is characterized in that a lamp bulb is connected in series between the power switch and the ballast; two ends of the lamp bulb are connected in parallel with a safety switch; and the power switch is a double-throw switch.
Description
Technical field
The utility model relates to a kind of fluorescent tube test circuit, the protective circuit of especially electrodeless fluorescent tube testboard.
Background technology
As the lighting of a new generation, electrodeless light fixture has the characteristics of long-life, high light efficiency, high-color rendering.Electrodeless lamp is made up of radio-frequency generator, coupler and fluorescent tube three parts.It is that electromagnetic field by radio-frequency generator is coupled in the fluorescent tube in the mode of induction, makes the gas avalanche ionization in the fluorescent tube, forms plasma; The plasma-excited atom gives off ultraviolet ray when returning ground state.The fluorescent material of tube inner wall is subjected to ultraviolet ray excited generation visible light.
Last procedure in the electrodeless lighting tube production technology is that fluorescent tube is carried out burn-in test.In test process, indivedual fluorescent tubes can be short-circuited because of the inherent quality reason, cause burning the accident of ballast or other components and parts.Also bring unsafe factor to ordinary production.
The utility model content
The purpose of this utility model is the deficiency that overcomes the above-mentioned background technology; a kind of electrodeless fluorescent tube testboard protective circuit is provided; this protective circuit should be able to be tested electrodeless fluorescent tube effectively, again can protective circuit in each parts, avoid parts to burn and the situation that influences safety takes place.
The technical scheme that the utility model provides is: electrodeless fluorescent tube testboard protective circuit comprises the mains switch of energized and the ballast of connecting electrodeless fluorescent tube; It is characterized in that being connected in series a bulb between mains switch and the ballast, bulb side also is connected with a discharge cock.
Described mains switch is a commutator.
The beneficial effects of the utility model are: owing to be connected in series a bulb in circuit, can be short-circuited because of the inherent quality reason in the test process as because of indivedual fluorescent tubes, whole voltage drops is born (discharge cock K switch 1 disconnects during test), the possibility of having avoided ballast to burn fully by bulb basically; But also eliminated unsafe factor, guaranteed the normal and orderly of production.
Description of drawings
Fig. 1 is an electrical block diagram of the present utility model.
Embodiment
Electrodeless fluorescent tube testboard protective circuit comprises the mains switch K of energized and the ballast Z that connects electrodeless fluorescent tube; It is characterized in that being connected in series a bulb Q between mains switch K and the ballast, bulb side also is connected with a discharge cock K1.Show among the figure: electric wire L, electric wire N insert fluorescent tube wiring DZ behind energized K switch, the ballast Z successively; Wherein access one a bulb Q in parallel and a discharge cock K1 between mains switch K and the ballast, the also available fuse of this discharge cock K1 replaces.
Described mains switch recommends to adopt biswitch.
Discharge cock K switch 1 needs to disconnect during the utility model work, and bulb Q switches on and lights; During if any tested bulb short circuit, because of voltage drop is born by bulb Q basically, so bulb brightness increases suddenly, (producing brightness regularly changes to produce stroboscopic simultaneously; The reason of stroboscopic is the cause of alternating current through the ballast inductor coil); The tested bulb of prompting tester is defective product.
Claims (2)
1. electrodeless fluorescent tube testboard protective circuit comprises the mains switch (K) of energized and the ballast (Z) of connecting electrodeless fluorescent tube; It is characterized in that being connected in series a bulb (Q) between mains switch and the ballast, bulb side also is connected with a discharge cock (K1).
2. the tube clamper of electrodeless fluorescent tube powder coating machine according to claim 1 is characterized in that described mains switch (K) is a commutator.
