For the ease of reader understanding, technology as a setting, we will describe traditional lamp and restriction that we find thereof.Propose the electrodeless plasma lamps driven by microwave source.Traditional configuration comprises: the gas filling containers (bulb) (such as, see U.S. Patent number 6,476,557B1 and Fig. 1 herein) of the luminous element containing xenon and such as sulphur or cesium bromide.It is inner that bulb is positioned at air resonance device/waveguide, and its utilization is provided by the source of such as magnetron and is introduced into the microwave energy of resonator/waveguide, to heat and make argon gas ion and evaporate sulphur with luminescence.In order to use the RF source of efficient and low cost, expect to be to be preferably lower than the frequency operation of 1GHz lower than about 2.5GHz by resonator/waveguide design.Conventional air resonator/the waveguide worked in the first-harmonic resonance pattern of resonator with 1GHz at least has the size being about 15cm length, and reason is that this length is about the half (λ/2) of the free space wavelength of the resonance frequency of resonator.
This causes found restriction.It is too huge for its size most of commercial lighting application that these restrictions comprise resonator/waveguide dimensions, and reason is that installation is not entered in typical ligthing paraphernalia (lighting apparatus) by resonator/waveguide.In addition, because bulb is placed in air/resonator chamber, therefore in the design of the reflector for the polytype lighting apparatus in commercial and industrial illumination application, the electric arc of bulb cannot be utilized.
The people such as Espiau are at U.S. Patent number 6,737, in the configuration proposed in 809B2, the air of resonator inside is replaced with aluminium oxide, make, because free space wavelength (the fundamental mode guide wavelength of this resonator/waveguide) reduces the square root of the effective dielectric constant of about resonator main body, therefore to cause the size of resonator/waveguide to reduce.In addition, see Fig. 2.This method has some advantage of the air resonance device be better than in U.S. Patent number 6,476,557B1 by the size reducing resonator, but the method has its defect.This defect may comprise higher manufacturing cost, the loss relevant to dielectric substance and the light from bulb and be stopped by dielectric substance.In the method, the electric arc of bulb can not be used, which has limited it in the use of throwing light in the polytype lighting apparatus in applying for commercial and industrial.
Fig. 1 shows the embodiment of RF Energy Coupling to the conventional air resonator/waveguide of gas filling containers (bulb).Air resonance device 400 is around the gas filling containers 410 being attached to bar 420.The cross section of resonator is shown in the bottom of Fig. 1.Size A shown in figure corresponds to the diameter of the air resonance device of the first-harmonic resonance work pattern of 900MHz, size A is about 16.5cm, and it is about the half (normally as the half of the free space guide wavelength of the effective wavelength of waveguide inside) of the free space wavelength of 900MHz.The size of this resonator is too huge for majority of illumination equipment.In addition, the electric arc of bulb is surrounded by the wall of resonator completely, and this makes to be difficult to when designing lighting device use traditional reflector and optics.
Fig. 2 shows the embodiment of RF Energy Coupling to the conventional dielectric resonator/waveguide of gas filling containers (bulb).Use input probe 540 by RF Energy Coupling in dielectric resonator 500.Resonator by RF Energy Coupling to the gas filling containers 510 being positioned at dielectric resonator inside, the major part of electric arc 515 by dielectric resonator around.Feedback probe 550 can be used for by beyond a small amount of RF Energy Coupling to resonator, and form feedback loop power on to make bulb together with amplifier and input probe.Show the cross section of this resonator in the bottom of Fig. 2, size B corresponds to the diameter of this resonator.Compared with the air resonance device shown in Fig. 1, an advantage of the method is that the size of resonator (for the fundamental mode run is designed) has been reduced the about square root of the effective dielectric constant of dielectric substance.Therefore, such as, when resonator is made with the aluminium oxide that dielectric constant is 9.4, be reduced to about 1/3 than the diameter of the air resonance device of the 900MHz shown in Fig. 1, be about 5.3cm (size B).The defect of the method is that this resonator must be made up of the dielectric substance of low RF loss, makes this resonator more expensive and is more difficult to manufacture.In addition, most of electric arc 515 of bulb is inner at dielectric substance, therefore, flexible design can not be used in lighting apparatus optics.By hereafter describing one or more execution mode of the present invention in more detail, it has overcome these and other restrictions.
Fig. 3 is the reduced graph of the execution mode of compact air resonance device/waveguide of the present invention.This diagram is only example, and it should not limit the scope of claim herein inadequately.Those of ordinary skill in the art will recognize other changes, select and amendment.Lamp housing 600 is made up of electric conducting material.Can by coated with conductive cover layer or by selecting electric conducting material to obtain conductivity.The example of conductive covering layer is aluminium paint or alternatively, lamp body can be made up of the sheet of conductive material of such as aluminium.In this embodiment, the bottom 625 of lamp body by wider diameter and the top 650 compared with narrow diameter form.Illustrated is cylindrical lamp body, but also can use rectangle or other shapes.Input coupling element 630 is connected to lamp body at top surface 631 place, and its other end is connected to the RF connector 611 through the opening 610 in lamp body.Input coupling element 630 can be made up of solid or hollow conductor or alternatively be made up of the dielectric substance with conductive coating.Export coupling element 120 and be connected to lamp body at bottom 605 place, its other end is connected to gas filling containers (bulb) 130.Export coupling element to be made up of solid or hollow electric conducting material or alternatively, can be made up of the dielectric substance with conductive coating.The top exporting coupling element is shaped as and closely holds gas filling containers.When exporting coupling element and being made up of solid conductor, the thin layer of dielectric substance or refractory metal is used as at bulb and the interface potential barrier that exports between coupling element.In a specific embodiment, gas filling containers is made up of such as quartz or translucent aluminium oxide or other applicable materials that is transparent or trnaslucent materials.Gas filling containers is filled with the luminous element (or it can contain multiple luminous element simultaneously) of the inert gas of such as argon or xenon and such as mercury, sodium, dysprosium, sulphur or the such as metal halide salt of indium bromide, scandium bromide, thallium iodide, Holmium tribromide, cesium iodide or other similar materials.Generally, by export coupling element 120 by RF energy capacitively, inductively or inductance and capacitor combination be coupled to bulb 130, ionization inert gas and evaporate luminous element and cause sending high light from lamp.In this embodiment, the electric arc 115 of bulb not by the wall of resonator/waveguide around.Feedback coupling element 635 is connected to the RF connector 621 through the opening 620 in lamp body.The other end of feedback coupling element is not connected to lamp body.
