The electrodeless lamp of general purpose type energy-saving

One, technical field: the utility model relates to electrodeless gaseous discharge lamp in a kind of lamp, belongs to novel daily lighting source.

Two, background technology:

Electrodeless lamp is a kind of brand-new electric light source of our times various countries focus development, according to open source information, electrodeless lamp mainly is made up of glass lamp and lamp circuit two parts, because there is not the necessary electrode of conventional electric light in the lamp, therefore being fed into that electric energy in the lamp generally needs frequency be that tens hertz civil power is hundreds of KHz even the high frequency more than the number megahertz through circuit conversion, electric field or magnetic field via high frequency are sent in the lamp, make working gas in the lamp produce gas discharge and finish the conversion of electric energy luminous energy.

Electrodeless lamp has very superior performance, because of electrodeless in the lamp, makes its working life very long, more than tens thousand of hours, and the luminous efficiency height.The shortcoming of existing electrodeless lamp is the manufacturing difficulty of lamp, the operating circuit complexity, and the cost height, up to RMB more than 3000 yuan, product is difficult to promote thus as every price of electrodeless lamp of external production.

The electricity-saving lamp fluorescent lamp of selling on the existing market, because the burn-out life restriction, the life-span is shorter, and generally in several thousand hours, especially electricity-saving lamp often has cold start-up, and cathodic sputtering is serious, and the life-span is outstanding problem especially.

The patent No. for " energy-saving current-changing electrodeless lamp " of (ZL2006200333528) though address the above problem, but following shortcoming is arranged on its structure: the one, lamp tube ends need be inserted in magnet ring, because the lamp tube ends distance is generally all very near, being inserted in of magnet ring is difficult, and limited the volume and the size of magnet ring, given the design of magnet ring and select all to bring problem.The 2nd, need be inserted in magnet ring by lamp tube ends, all increased difficulty for structure, safety in utilization, the interference of solution high-frequency electromagnetic of whole lamp.

Three, summary of the invention:

This uses the energy-conservation electrodeless lamp of novel proposition, exactly for addressing the above problem, especially solves the scheme of " energy-saving current-changing electrodeless lamp " shortcoming.Fig. 1 is its structural circuit schematic diagram, has electrodeless fluorescent tube 1, charges into mercuryvapour and argon or krypton in the fluorescent tube, and tube inner wall is coated with fluorescent material, lamp circuit 4, high-frequency current transformer 2.

It is characterized in that;

1, lamp circuit 4 employing operating frequencies are the electronic oscillating circuit of 0.1MHz～0.5MHz, high-frequency current transformer 2 is magnetic cores 2.1, be wound with energy regenerative coil 2.2 and secondary coil 2.3 above, energy regenerative coil 2.2 is connected with the lead-in wire 3 of lamp circuit output, and the lead-in wire 6 in secondary coil 2.3 and the fluorescent tube 1 is connected.

2, fluorescent tube 1 is identical with straight tube fluorescent lamp overall dimensions shape with existing power saving fluorescent lamps, be straight tube shape, annular, circle, H shape, single U-shaped, two D shape, dual U-shaped, three U-shapeds, many U-shapeds, and these fluorescent tubes all can with the whole lamp of lamp circuit 4 and high-frequency current transformer 2 being combined into one.

3, there is the lead-in wire 6 that stretches in the lamp at fluorescent tube 1 two ends, and after the glass-tube sealing, fluorescent tube is evacuated, and the outer surface at fluorescent tube 1 two ends respectively is wound with one group of actuating coil 7, and every group one end is connected the other end and unsettled with secondary coil 2.3.

4, fluorescent tube 1 outer surface is coated with the transparency conducting layer 1.2 of ground connection, disturbs to improve its high-frequency electromagnetic.

5, the lamp circuit 4 of frequency 0.1MHz～0.5MHz is made up of rectifier 4.1, high frequency filter 4.2, driver 4.3 and oscillator 4.4 and matching network 4.5.

After the energising, lamp circuit 4 produces 0.1MHz～0.5MHz high frequency voltage, energy regenerative coil 2.2 is equivalent to the elementary of current transformer, when high-frequency current during through energy regenerative coil 2.2 circulation, go out secondary current at secondary coil 2.3 underexcitations, different according to the number of turns of two coils and line footpath, the size of secondary current can be adjusted.Secondary current produces high-frequency electric field by behind the actuating coil 7, forms bigger operating current in fluorescent tube, makes lamp works in the arc discharge state, thereby produces stronger light radiation, and luminous efficiency is very high.

The utility model beneficial effect:

1,, kept the effect of existing electrodeless lamp long working life because of electrodeless in the lamp.Adopt high-frequency current transformer energy regenerative and coupling, can be convenient to regulate the voltage at two ends of fluorescent tube and the operating current in the lamp, so that lamp is operated in optimum state.

2, the magnetic core of high-frequency electrical depressor is convenient to install and is regulated, and makes the outward appearance of lamp the same with common energy-saving lamp and fluorescent lamp, with the current all electricity-saving lamps and the light fixture compatibility of fluorescent lamp, can utilize current all light fixtures, and be beneficial to the integrated of electrodeless lamp like this.

3, can directly use current all power saving fluorescent lampss and fluorescent tube, make all power saving fluorescent lampss and fluorescent tube directly transform electrodeless lamp as, improve its working life greatly.

4, can utilize the production equipment of current electricity-saving lamp and fluorescent lamp to carry out full-automation production, thereby improve the production efficiency and the rate of finished products of electrodeless fluorescent tube greatly, reduce the production cost of electrodeless fluorescent tube greatly, be very advantageous in the reduction of electrodeless lamp price and the popularization of electrodeless lamp.

5, the utility model is energy-conservation, and nonferrous materials is saved in environmental protection, and the conserve water resource is good green illumination light source.
