The outside of base of the glass bulb is fixedly connected with a socket, and a high-frequency electromagnetic wick is disposed in the cylindrical cavity. Then the utility model of the high-frequency and non-polar lamp has the advantages of simple process, stable mercury pressure, high luminous efficiency and prefect starting property in low temperature.
Description
The utility model relates to a kind of light fixture, particularly relates to a kind of high frequency electrode-free lamp.
The high frequency electrode-free lamp is a kind of long-life, and is pollution-free, high efficiency new type electro source.The high frequency electrode-free lamp that uses mainly comprises at present: a vacuum-tight discharge vessel, and it contains metal vapors and the inert gas of power supply from the metal of usefulness, and at tail end a recessed cavity is arranged; Main mercurial memotron and exhaust tube are positioned over sealing-in place of cavity and discharge vessel shell; In the cavity of discharge vessel, an electric coil is on the sleeve pipe of being made by synthetic material; The iron core that the electro permanent magnetic material is made is contained in the sleeve of electric coil coiling; A tubular container that closes, one in the iron core that magnetic material is made, other one is stretched out together outside the cavity of discharge vessel with the sleeve made by synthetic material, fixedlys connected with bearing; A high frequency electric source links to each other with electric coil.This electrodeless fluorescence lamp is owing to the main mercurial memotron and take out the place that connects that pipe is placed on cavity and discharger shell, makes that the manufacturing of whole discharge vessel is very difficult, and technological requirement is very high, and main mercurial pipe and exhaust tube breakage easily; In addition, the main mercurial memotron temperature fluctuation of this lamp is big, and mercury vapour is pressed unstable, has influenced the normal performance of luminous efficiency.
The purpose of this utility model is that a kind of manufacturing process of proposition is simple, mercury vapour is pressed and stablized the high frequency electrode-free lamp that luminous efficiency is high.
For achieving the above object, the utility model high frequency electrode-free lamp comprises: the vacuum-packed inner surface of a pear shape scribbles the glass discharging bulb of fluorescent material, be filled with mercury vapour and inert gas in it, there is the column type cavity of an indent at its base portion center, the fixedly connected base in the base portion outside of this glass discharging bulb, in this column type cavity, there is a periphery to be wound with the iron core of the magnetic material of high temperature wire coil, this high temperature wire coil connects high frequency electric source by shielded conductor, the center fixation that it is characterized in that the iron core of described magnetic material connects a heat conduction wick, this heat conduction wick lower end is shaped on the garden dish, this dish outside, garden is fixedly connected on the base by screw thread, be shaped on the through hole of shielded conductor on this garden dish, the bottom of glass discharging bulb has mutual non-conterminous main mercurial memotron and exhaust tube.
As optimization, described heat conduction wick is connected on the iron core of magnetic material by the end screw.
In order to strengthen heat sinking function, described heat conduction wick center has louvre.
Fixing for convenience, described base is fixedly connected on the base portion outside of glass discharging bulb by resin.
In order to make resin bed have resiliency, described elastic resin is an elastic epoxy resin glue.
Be welded with auxiliary mercurial on the column type cavity in the described glass discharging bulb.Should the effect of lighting fast be arranged auxiliary mercurial to cold-starting.
After adopting technique scheme,, manufacture process requirement is reduced greatly because the outlet of mercurial pipe and blast pipe and cavity is positioned at same end; In addition, the mercurial pipe does not contact with metab, guaranteed not cracky of glass discharging bulb on the one hand, add the loss that has reduced heat on the one hand, make the mercurial pipe be in normal isoperibol always, guaranteed the stability that mercury vapour is pressed, thereby fully improved luminous efficiency, the auxiliary mercurial that is contained in the glass discharging bulb has the effect of lighting fast to cold-starting.In addition, the glass discharging bulb adopts the pear shape of ordinary incandescent lamp, thereby makes this lamp more be applicable to the lighting environment of common fluorescent lamp.Therefore, the utility model high frequency electrode-free light fixture has that manufacturing process is simple, mercury vapour press stable, luminous efficiency height, the advantage that low-temperature startup performance is good.
Accompanying drawing is the structural representation of the utility model high frequency electrode-free lamp.
Be further described below in conjunction with accompanying drawing, the utility model high frequency electrode-free lamp comprises that the inner surface of a pear shape scribbles the vacuum-packed glass discharging bulb 1 of fluorescent material, be filled with mercury vapour and inert gas in it, there is the column type cavity 2 of an indent at its base portion center, the base portion outside of this glass discharging bulb 1 is by the fixedly connected base 3 of elastic epoxy resin glue, in this column type cavity 2, there is a periphery to be wound with the iron core 5 of the magnetic material of high temperature wire coil 4, this high temperature wire coil 4 connects high frequency electric source 7 by shielded conductor 6, the center of the iron core 7 of described magnetic material possesses a heat conduction wick 8, the iron core 7 of this magnetic material is fixed together with heat conduction wick 8 by the screw 12 of end, these heat conduction wick 8 lower ends are shaped on garden dish 9, this garden is coiled 9 outsides and is fixedly connected on the base 3 by screw thread, be shaped on the through hole of shielded conductor 6 on this garden dish 9, the bottom of glass discharging bulb 1 has mutual non-conterminous main mercurial memotron 10 and exhaust tube 11.Be welded with auxiliary mercurial 13 on the column type discharge cavity 2 in the described glass discharging bulb 1.
The iron core of magnetic material adopts the ferronickel material to make, and the heat conduction wick adopts lead to make, and base adopts stainless steel to make.When this lamp power during less than 100W the heat conduction wick can use cheap hollow or real core lead rod; Should select heat pipe when power for use during greater than 100W,, should outside the glass discharging bulb, be coated with the conducting film of layer of transparent,, should be coated with the diaphragm of layer of transparent at the glass discharging bulb, and then be coated with one deck three primary colors fluorescent powder in order to reduce light decay for preventing high frequency radiation and conducted interference.
The utility model high frequency electrode-free lamp produces a power supply by high frequency electric source, import the high temperature wire coil by shielding conductor, produce a high frequency magnetic field by this coil and magnetic core again, mercury atom in this magnetic excitation glass discharging bulb and inert gas produce electron motion, produce ultraviolet ray through power conversion, ultraviolet ray is converted into visible light by the fluorescent material on the glass discharging bulb inner surface.
