Abstract

The utility model relates to an electroless energy-saving lamp. The electroless energy-saving lamp is characterized in that: a lamp cap at the upper part is connected with a fluorescent lamp bulb at the bottom part by a partition board between the lamp cap and the fluorescent lamp bulb; an electronic ballast in the lamp cap is fixedly arranged on the partition board; a sunken cavity body is arranged in the inner center of the fluorescent lamp bulb, a magnetic coil is arranged in the sunken cavity body, a step aluminum tube is used as a core tube of the magnetic coil, a radiating chamber is formed in the sunken cavity body by a large-diameter step tube at the tail part of the step aluminum tube, a radiating window is arranged on the partition board, the radiating chamber where the step aluminum tube locates is communicated with the external part by the radiating window; the electronic ballast is electrically connected with the magnetic coil. The electroless energy-saving lamp is that: an electrode and a lamp filament arranged in a lamp tube of the traditional energy-saving lamp are replaced by the magnetic coil arranged at the outer part of the bulb, thus solving the problem of the service life of the energy-saving lamp is limited by the lamp filament.

Description

Electrodeless electricity-saving lamp

Technical field

The utility model relates to electricity-saving lamp, a kind of electricity-saving lamp that is used for normal lighting.

Background technology

Aspect lighting tube structure, the fluorescent tube of traditional energy-saving lamp mainly contains three kinds of U-shaped, H shape and spiralitys, all built-in filament of the fluorescent tube of three kinds of profiles, and the surface of filament scribbles one deck electronics powder.After the ballast energising, filament begins heating, greatly when the 1160K temperature, filament begins emitting electrons, the electron collision ar atmo produces inelastic collision, has obtained energy after the ar atmo collision and has clashed into mercury atom again, and mercury atom transition after absorbing energy produces ionization, send the ultraviolet ray of 253.7nm, ultraviolet ray excited light-emitting phosphor.The electricity-saving lamp of this version depends on filament work, in case filament is fused because of the various Chang Yinsu of leading, or the electronics pruinescence exhausts, emitting electrons no longer, and electricity-saving lamp just can not be luminous.Obviously, filament itself is a critical component that influences the electricity-saving lamp life-span owing to be subjected to the restriction of filament, traditional energy-saving lamp general less than 8000 hours designed life, often have only 2000-5000 hours actual life, and this makes the phenomenon of not cost saving of electricity-saving lamp exist always.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of electrodeless electricity-saving lamp that can not place restrictions on useful life again because of filament being provided.

The utility model technical solution problem adopts following technical scheme:

The design feature of the electrodeless electricity-saving lamp of the utility model is:

Top lamp holder and bottom fluorescent lamp bulb are connected by dividing plate therebetween, and the electric ballast that is arranged in lamp holder is fixedly installed on the dividing plate; Fluorescent lamp bulb central authorities of portion within it has caveli body, inserted solenoid in the caveli body, solenoid is to be the core pipe with the step aluminum pipe, the step aluminum pipe forms the heat radiation chamber with the big footpath step pipe of its afterbody in caveli body, thermal window is set on the dividing plate, and the heat radiation chamber at step aluminum pipe place is by thermal window and external communications; Electric ballast is electrically connected with solenoid.

Compared with the prior art, the utility model beneficial effect is embodied in:

1 the utility model is to replace traditional energy-saving lamp to place filament in the fluorescent tube body with the solenoid that places the bulb outside, and the energy of ionization is provided to bulb internal discharge gas with solenoid.Because solenoid does not exist material to consume phenomenon, this makes electricity-saving lamp no longer include the restriction in life-span.

2, the utility model is provided with the heat radiation cavity configuration and is provided with rationally, and good heat dissipation effect has effectively guaranteed the functional reliability of each device.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model circuit block diagram.

Number in the figure: 1 top lamp holder, 2 electric ballasts, 3 dividing plates, 4 step aluminum pipes, 5 fluorescent lamp bulbs, 6 discharging chambers, 7 solenoids, 8 cavelis, 9 heat radiation chambeies, 10 leads, 11 thermal windows.

Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings

Embodiment

Referring to Fig. 1, in the present embodiment, top lamp holder 1 and bottom fluorescent lamp bulb 5 are connected by dividing plate 3 therebetween, and the electric ballast that is arranged in lamp holder 1 is fixedly installed on the dividing plate 3; Fluorescent lamp bulb 5 with discharging chamber 6 central authorities of portion within it has caveli 8, inserted solenoid 7 in the caveli body 8, solenoid 7 is to be the core pipe with step aluminum pipe 4, step aluminum pipe 4 forms heat radiation chamber 9 with the big footpath step pipe of its afterbody in caveli body 8, thermal window 11 is set on the dividing plate 3, the heat radiation chamber 9 at step aluminum pipe 4 places is by thermal window 11 and external communications, and reasonably radiator structure can be guaranteed electricity-saving lamp normal useful life; Electric ballast 2 is electrically connected by being connected lead 10 with solenoid 7.

Referring to Fig. 2, the circuit structure of the electric ballast in the present embodiment is:

Behind the 220V civil power input electric ballast, after the Filtering Processing through the EMI filter circuit, be sent to high-voltage rectifier, processing through high-voltage rectifier, the 220V civil power becomes pulsating dc voltage, this pulsating dc voltage is transformed into power factor again and is higher than 0.85 stable DC voltage through behind the pfc circuit.This direct voltage provides power supply for high-frequency oscillating circuits, makes high-frequency oscillating circuits produce high frequency voltage, through after the conversion of high-frequency output circuit, promotes load (electrodeless electricity-saving lamp) work.For preventing that the load bulb from damaging because of various abnormal conditions such as gas leakage, breakage, loose contact, broken string cause electric ballast; between high frequency output and high-frequency oscillating circuits, be provided with the PTC protective circuit; when in case above-mentioned various abnormal conditions take place; PTC will be high-impedance state; high-frequency oscillating circuits is quit work, until trouble shooting.

Because circuit has adopted the PFC high-power factor correcting circuit, can make the power factor of electrodeless electricity-saving lamp be higher than national standard, reaches more than 0.85; Owing to adopted high-frequency oscillating circuits, the operating frequency that can make electrodeless electricity-saving lamp has thoroughly solved the intrinsic stroboscopic phenomenon of common energy-saving lamp up to 2.65MHz; Owing to adopted the EMI filter circuit, the electromagnetic interference limit value that can make electrodeless electricity-saving lamp is under national standard.

Simultaneously, the utility model can make reach more than 100,000 hours the designed life of lamp under the situation that the The Key Electron Device quality guarantees to some extent.
