Abstract
An electrodeless fluorescent lamp belongs to the fluorescent lamp illumination technology and gas-discharge lamp technology field and is characterized in that the lamp comprises a sealed close-loop-typed glass tube which is charged with the mercury vapor and the cushioning gas. The inner wall of the glass tube is homogeneously covered with the fluorescent powder of three primary colors, the symmetrical two ends of the close-loop-typed continuous glass tube are respectively equipped with an oblate glass tubes, which are respectively hugged closely by coils which is used to wind the copper wire and two semi-symmetric magnetic cores which is coincident with the outline of the lamp tube, and two groups of the coils are connected with the output end of a power driver. The utility model has the advantages that the reliability is enhanced, the life is prolonged to 5 to 10 thousand hours, the luminous flux is high, the illuminance is large, and according to requirements choosing different proportions, frequencies and current sizes of the fluorescent powder of three primary colors, different lamps with different powers can be achieved which has different lamp colors, mild light, excellent color rendering, no stroboscopic, no electromagnetic radiation and no conducted interference. Thereby the utility model improves the product capability and is a very practical design.
Description
Technical field
Belonging to fluorescent lighting technology and gaseous discharge lamp technical field, exactly, is a kind of electrodeless fluorescent lamp technology.
Technical background
Mostly present fluorescent lamp for lighting is the inflation fluorescent tube of band filament or various electrodes; Heating produces ion to this fluorescent tube by filament, and bump gas ionization luminous lighting exists the life-span short, and illumination is little, and the shortcoming of stroboscopic is arranged.
Summary of the invention
The utility model provides a kind of illumination big, and variation in moulding is attractive in appearance, does not want heated by electrodes, thereby can improve a kind of electrodeless fluorescent lamp in life-span.
The technical scheme that the utility model is taked:
A kind of electrodeless fluorescent lamp comprises fluorescent tube that contains the discharge gas filler and the AC power that is added on the fluorescent tube, and its structure is: a sealing ring that is filled with mercuryvapour and buffer gas closes the shape glass tube, and the glass-tube inwall evenly covers three primary colors fluorescent powder; Closing the symmetrical two ends of the continuous glass tube of shape at ring, respectively is oblate glass-tube, by the coil that twines copper cash, fills the span of a man's arms respectively with the two hemihedrism magnetic cores that the fluorescent tube profile matches, and two groups of coils are connected with the analog line driver output; Its core material is MnZn or NiZn ferrite; A sealing ring closes the shape glass tube, and its ring footpath is 10-80 centimetre, and the effective cross-section of fluorescent tube is the 1.5-40 square centimeter; Analog line driver, its driving frequency are 50KHz-1MHz, and discharging current is 50mA-10A, and high frequency power is 10-2000W; Twine the coil of copper cash, be made up of 1-100 thigh twisted wire, the number of turn of its coil is the 10-500 circle; Ring closes the shape glass tube, and its cross sectional shape is oblate, or circular, oval, square, rectangle, hexagon; Be filled with mercuryvapour and buffer gas, contain 50mg-2g mercury; Buffer gas is argon gas or krypton gas.
The good effect of implementing behind the utility model is: because lamp is electrodeless, so reliability height, life-span are long, can reach 5-10 ten thousand hours; Luminous flux height, illumination are big; Select three primary colors fluorescent powder different proportion and different frequency, size of current on demand, can obtain different light colors, photochromic soft, color rendering good, the lamp of the various different capacities of no stroboscopic, electromagnetic-radiation-free and conducted interference, improved properties of product.

Embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings
A kind of electrodeless fluorescent lamp, comprise fluorescent tube that contains the discharge gas filler and the AC power that is added on the fluorescent tube, its structure is: a sealing ring that is filled with mercuryvapour and buffer gas 6 closes shape glass tube 1, the glass-tube inwall evenly covers three primary colors fluorescent powder 7, closing the symmetrical two ends of the continuous glass tube of shape at ring, respectively is oblate glass-tube, by the coil 4,5 that twines copper cash, fill the span of a man's arms respectively with the two hemihedrism magnetic cores 2,3 that the fluorescent tube profile matches, two groups of coils are connected with analog line driver 8 outputs.Core material is MnZn or NiZn ferrite.Sealing ring closes the shape glass tube, and its ring footpath is 10-80 centimetre; The effective cross-section of fluorescent tube is the 1.5-40 square centimeter.Analog line driver, its driving frequency are 50KHz-1MHz, and discharging current is 50mA-10A, and high frequency power is 10-2000W.Twine the coil of copper cash, be made up of 1-100 thigh twisted wire, the number of turn of its coil is the 10-500 circle.Ring closes the shape glass tube, and its cross sectional shape is oblate or circular, oval, square, rectangle, hexagon.Be filled with mercuryvapour and buffer gas, contain 50mg-2g mercury; Buffer gas is argon gas or krypton gas.
Its course of work is: after analog line driver passes to AC220V or 110V power supply, just can produce the alternating current of 50-1000KC, the current strength scope is 0.1-10A, this alternating current produces alternating electromagnetic field by the magnetic core on fluorescent tube, this moment, visual transformer coil 4,5 was elementary, and the ion flow that produces in the fluorescent tube that is surrounded by magnetic core secondary as transformer, when the voltage of alternation and electric current reach certain value, can make the ion flow discharge in the shell send the ultraviolet aura, thereby the fluorescent material that activates tube wall is and luminous, and this moment, electrodeless fluorescent lamp was just lighted.
