Background technology

Lighting device makes the mankind feel more comfortable, joyful in work and living environment, and development gradually along with led technology, characteristics such as its low power consuming that has, long service life, volume is little, reaction is fast make LED light lamp replace traditional tungsten lamp gradually.The electrodeless lamp that a kind of combined with fluorescent lamp gas discharge principle and high-frequency electromagnetic induction principle are arranged in addition, also can replace traditional tungsten lamp, and the heat dissipation problem that does not solve fully as yet compared to LED light lamp, the heat that electrodeless lamp produced is far below LED light lamp, and electrodeless lamp monomer power greatly, effectively uses the electric energy height, is the practical light source of ripe and long-life of commercialization in the technology of new generation, high light efficiency.

Existing electrodeless light fixture mainly comprises annular lamp tube, the coupler of socket annular lamp tube, holder structure for coupler installing and electric connection, annular lamp tube inside is filled with inert gas and mercury vapor, the annular lamp tube inwall is coated with fluorescent material, electrodeless light fixture is installed on outside lamp socket by holder structure, after outside lamp socket applied electric power, to make electric current pass through holder structure and input coupler, coupler is based on the principle of electromagnetic induction, can in annular lamp tube, set up magnetic field, and make inert gas generation gas discharge and excite mercury vapor to give off ultraviolet ray, fluorescent material absorbs ultraviolet ray and irradiates visible light.

And, the mechanism of this gas discharge has negative resistance property, if electrodeless light fixture is directly received voltage source, can be burnt because of electric current increases to the rated current that surpasses electrodeless light fixture rapidly, therefore, must install external ballast in addition additional at lamp socket, external ballast is series on the circuit between lamp socket and the coupler, to stablize the operating current of light fixture, yet, external ballast is installed in lamp socket, must on lamp socket, produce the expense of circuit change and the recondition expense of other winding structure, and increase complicated extra assignment program, therefore make the lamp installation cost increase.

The utility model content

The purpose of this utility model is to provide a kind of electrodeless light fixture of outer coupled mode with built-in ballast, has the function from ballast, can exempt extra circuit change expense of installing ballast and producing and repacking cost on lamp socket.

To achieve the above object, of the present utility modelly provide a kind of electrodeless light fixture of outer coupled mode, comprising with built-in ballast:

Holder structure;

Loop formula fluorescent tube is arranged at this holder structure;

Coupler comprises the core retainer plate of this loop formula fluorescent tube of socket and twines the conductor wire of this core retainer plate; And

Ballast is installed in this holder structure inside and electrically connects this conductor wire.

Compared to prior art, the utlity model has following effect:

The electrodeless lamp installation of outer coupled mode that will have built-in ballast is when lamp socket, because light fixture itself reaches function from ballast by its ballast, do not need on lamp socket, to install in addition again ballast, circuit required when the energy saving is installed in lamp socket with external ballast changes expense and complex job program, and can exempt the recondition expense that other winding is constructed, so as to reducing the lamp installation cost, quite has economic benefit.

Embodiment

Relevant detailed description of the present utility model and technology contents are described as follows conjunction with figs., yet appended accompanying drawing purposes as an illustration only is not to be used to limit to the utility model.

The utility model please refer to Fig. 1 to shown in Figure 3 relevant for a kind of electrodeless light fixture of outer coupled mode with built-in ballast, and this electrodeless light fixture comprises holder structure 100, loop formula fluorescent tube 200, coupler 300 and ballast 400.

Holder structure 100 comprises shell block 110 and is fixed in the electric connection 120 of shell block 110 1 ends, and electric connection 120 is used to be connected in the lamp socket (not shown).

Shell block 110 comprises bottom 111, top cover 112 and bearing part 113.

Bottom 111 is organized mutually with top cover 112 and is established, and between bottom 111 and top cover 112, be formed with cavity volume 114, further define its joint construction, bottom 111 and top cover 112 are connected to the two ends of bearing part 113, be that bearing part 113 connects bottoms 111 and top cover 112 and between bottom 111 and top cover 112, and formation cavity volume 114 between bottom 111 and the bearing part 113.

In addition,,, offer groove 115, offer perforation 116 at bearing part 113 as the surface of top cover 112 at top cover 112.

Loop formula fluorescent tube 200 is arranged at holder structure 100, further defining, is to be arranged at shell block 110 other ends, and promptly shell block 110 sets up arrangement for loop formula fluorescent tube 200, further defining, is that top cover 112 sets up arrangement for loop formula fluorescent tube 200 again.

In addition, loop formula fluorescent tube 200 forms socle 210, forms socle 210 as projection, and socle 210 is inserted in the groove 115.

Loop formula fluorescent tube 200 is ring-type fluorescent tube or frame shape fluorescent tube, but does not exceed with these configurations.

The space is filled with inert gas and mercury vapor in the pipe of loop formula fluorescent tube 200, and inside pipe wall then is coated with fluorescence coating.

Coupler 300 comprises core retainer plate 310, conductor wire 320 and supports and protect hoop 330.

Core retainer plate 310 socket loop formula fluorescent tubes 200, core retainer plate 310 is a ferromagnetic ring, but do not exceed with this member, conductor wire 320 twines core retainer plate 310 and is arranged in the perforation 116, supports and protects 330 cover cap core retainer plates 310 of hoop and conductor wire 320, and support and protect hoop 330 for being fixedly connected on holder structure 100, further define, for being fixed in shell block 110, again further, promptly be fixed in top cover 112.
