For the ease of the reader understanding, technology as a setting, we will describe traditional lamp and the restriction that we found thereof.Electrodeless plasma lamps by the microwave source driving has been proposed.Traditional configuration comprises: contain xenon and such as the gas filling containers (bulb) of the luminous element of sulphur or cesium bromide (for example, referring to U.S. Patent number 6,476,557B1 and Fig. 1 herein).Bulb is positioned at air resonator/waveguide inside, and it utilizes the microwave energy that is provided and be introduced into resonator/waveguide by the source such as magnetron, to heat and to make argon gas ionization and evaporation sulphur with luminous.In order to use efficient and RF source cheaply, expectation with resonator/waveguide design for to be lower than about 2.5GHz and to be preferably lower than the frequency work of 1GHz.Conventional air resonator/the waveguide of working in the first-harmonic resonance pattern of resonator with 1GHz has at least and is about a long size of 15cm, and reason is that this length is about half (λ/2) of free space wavelength of the resonance frequency of resonator.
This causes the restriction found.These restrictions comprise that resonator/waveguide dimensions its size for most of commercial lightings are used is too huge, and reason is that resonator/waveguide will install to enter in the typical ligthing paraphernalia (lighting apparatus).In addition, because bulb places in air/resonator chamber, therefore in the design of the reflector that is used for polytype lighting apparatus that the commercial and industrial illumination uses, can't utilize the electric arc of bulb.
People such as Espiau are at U.S. Patent number 6,737, in the configuration that is proposed among the 809B2, replace the air of resonator inside with aluminium oxide, make because free space wavelength (the first-harmonic pattern guide wavelength of this resonator/waveguide) has reduced the square root of the effective dielectric constant of about resonator main body, therefore cause the size of resonator/waveguide to reduce.In addition, referring to Fig. 2.This method has by the size that reduces resonator and is better than at U.S. Patent number 6,476, some advantage of the air resonator among the 557B1, but this method has its defective.This defective may comprise higher manufacturing cost, the loss relevant with dielectric substance and be stopped by dielectric substance from the light of bulb.In the method, can not use the electric arc of bulb, this has limited its use in the polytype lighting apparatus that is used for commercial and industrial illumination application.
Fig. 1 shows the embodiment that the RF energy is coupled to the conventional air resonator/waveguide of gas filling containers (bulb).Air resonator 400 is around the gas filling containers 410 that is attached to bar 420.Show the cross section of resonator in the bottom of Fig. 1.Size A shown in the figure is corresponding to the diameter with the air resonator of the first-harmonic resonance pattern work of 900MHz, size A is about 16.5cm, and it is about the free space wavelength of 900MHz half (normally as the free space guide wavelength of the effective wavelength of waveguide inside half).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 fully, and this makes and be difficult to use traditional reflector and optics when the design lighting device.
Fig. 2 shows the embodiment that the RF energy is coupled to the conventional dielectric resonator/waveguide of gas filling containers (bulb).Use input probe 540 that the RF energy is coupled in the dielectric resonator 500.Resonator is coupled to the RF energy and is positioned at dielectric resonator gas inside filling containers 510, and the major part of electric arc 515 is centered on by dielectric resonator.Feedback probe 550 can be used for a small amount of RF energy is coupled to beyond the resonator, and form feedback loop so that bulb powers on together with amplifier and input probe.Show the cross section of this resonator in the bottom of Fig. 2, size B is corresponding to the diameter of this resonator.Compare with the air resonator shown in Fig. 1, an advantage of this method is that the size (the first-harmonic pattern that is operation is designed) of resonator has been reduced the square root of the effective dielectric constant of about dielectric substance.Therefore, for example, be under 9.4 the aluminium oxide situation about making with dielectric constant at resonator, be reduced to approximately 1/3 than the diameter of the air resonator of the 900MHz shown in Fig. 1, be about 5.3cm (size B).The defective of this method must be made by the dielectric substance of low RF loss for this resonator, makes that this resonator is more expensive and more is difficult to manufacturing.In addition, most of electric arc 515 of bulb is in dielectric substance inside, therefore, can not flexible design be used for the optics of lighting apparatus.By hereinafter 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 resonator/waveguide of the present invention.This diagrammatic sketch only is an example, and it should not limit the scope of this paper claim inadequately.Those of ordinary skill in the art will recognize other variations, selection and revise.Lamp housing 600 is made by electric conducting material.Can be by the coated with conductive cover layer or by selecting electric conducting material to obtain conductivity.The example of conductive covering layer is an aluminium paint or replacedly, lamp body can be made by the electric conducting material thin plate such as aluminium.In this embodiment, lamp body is formed by the bottom 625 of wider diameter with than the top 650 of narrow diameter.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 places, and its other end is connected to the RF connector 611 of the opening 610 that passes in the lamp body.Input coupling element 630 can be made or replacedly be made by the dielectric substance with conductive coating by solid or hollow conductor.605 places are connected to lamp body to output coupling element 120 in the bottom, and its other end is connected to gas filling containers (bulb) 130.The output coupling element can be made or replacedly, can be made by the dielectric substance with conductive coating by solid or hollow electric conducting material.The top of output coupling element is shaped as and closely holds the gas filling containers.Under output coupling element situation about making by solid conductor, with the thin layer of dielectric substance or refractory metal as at bulb and the interface potential barrier of exporting between the coupling element.In embodiment, the gas filling containers is by making such as quartzy or translucent aluminium oxide or other suitable materials transparent or trnaslucent materials.The gas filling containers is filled with such as the inert gas of argon or xenon with such as mercury, sodium, dysprosium, sulphur or such as the luminous element (perhaps it can contain multiple luminous element simultaneously) of the metal halide salt of indium bromide, scandium bromide, thallium iodide, Holmium tribromide, cesium iodide or other similar materials.Generally, by output coupling element 120 with RF energy electric capacity ground, inductively or inductance and electric capacity be coupled to bulb 130 in combination, ionization inert gas and evaporate luminous element and cause sending high light from lamp.In this embodiment, the electric arc 115 of bulb is not centered on by the wall of resonator/waveguide.Couples back element 635 is connected to the RF connector 621 of the opening 620 that passes in the lamp body.The other end of couples back element is not connected to lamp body.
