Sequentially, but common implication should be used to be understood.
Understand for the ease of reader, as background technology, the limitation that we will describe traditional lamp and its we are had found.
The electrodeless plasma lamps driven by microwave source have been proposed.Traditional configuration includes：Contain xenon and such as sulphur or bromination
The gas filling container (bulb) of the illuminator of caesium (for example, with reference to U.S. Patent number 6,476,557B1 and Fig. 1 herein).
Bulb is located inside air resonance device/waveguide, and it, which is utilized, is provided by the source of such as magnetron and be introduced into resonator/waveguide
Microwave energy, to heat and make argon gas ion and evaporate sulphur with luminous.In order that with efficient and inexpensive RF sources, expect by
Resonator/waveguide design be with below about 2.5GHz and be preferably lower than 1GHz frequency work.With 1GHz in resonator
Conventional air resonator/the waveguide worked in fundamental resonance mode at least has a size of about 15cm length, and reason is
The length is about the half (λ/2) of the free space wavelength of the resonant frequency of resonator.
This causes found limitation.These limitations include resonator/waveguide dimensions for most of commercial lighting applications
For its size it is excessively huge, reason is that resonator/waveguide will install not enter in typical ligthing paraphernalia (lighting apparatus).
Further, since bulb is placed in air/resonator cavity, therefore polytype photograph in application is illuminated for commercial and industrial
In the design of the reflector of bright equipment, it is impossible to utilize the electric arc of bulb.
Espiau et al. replaces resonance with aluminum oxide in U.S. Patent number 6, the configuration proposed in 737,809B2
Air inside device so that because free space wavelength (the fundamental mode guide wavelength of the resonator/waveguide) is reduced and about resonated
The square root of the effective dielectric constant of device main body, therefore cause the size of resonator/waveguide to reduce.In addition, referring to Fig. 2.It is this
Method has some excellent of the air resonance device being better than in U.S. Patent number 6,476,557B1 by reducing the size of resonator
Gesture, but this method has its defect.This defect potentially includes higher manufacturing cost, the damage related to dielectric substance
Consumption and the light from bulb are stopped by dielectric substance.In the method, it is impossible to which, using the electric arc of bulb, which has limited it
Use in polytype lighting apparatus in application is illuminated for commercial and industrial.
Fig. 1 is shown the implementation of conventional air resonator/waveguide of RF energy couplings to gas filling container (bulb)
Example.Air resonance device 400 surrounds the gas filling container 410 for being attached to bar 420.The section of resonator is shown in Fig. 1 bottom.
Size A shown in figure corresponds to the diameter of the air resonance device worked with 900MHz fundamental resonance mode, and size A is about
16.5cm, the half of its free space wavelength for being about 900MHz is (typically as the freely empty of the EWL inside waveguide
Between guide wavelength half).The size of the resonator is excessively huge for majority of illumination equipment.In addition, the electric arc of bulb is complete
Surrounded by the wall of resonator, this to be difficult with traditional reflector and optics when designing lighting device.
Fig. 2 is shown the reality of conventional dielectric resonator/waveguide of RF energy couplings to gas filling container (bulb)
Apply example.Using input probe 540 by RF energy couplings into dielectric resonator 500.Resonator is by RF energy couplings to being located at
Gas filling container 510 inside dielectric resonator, the major part of electric arc 515 is surrounded by dielectric resonator.Can will be anti-
Presenting probe 550 is used for beyond a small amount of RF energy couplings to resonator, and is formed instead together with amplifier and input probe
Road is fed back to so that electric on bulb.The section of the resonator is shown in Fig. 2 bottom, size B corresponds to the diameter of the resonator.
Compared with the air resonance device shown in Fig. 1, an advantage of this method is the size of resonator (for the fundamental mode of operation
It is designed) it is reduced the square root of the about effective dielectric constant of dielectric substance.Thus, for example, normal with dielectric in resonator
In the case that number is made for 9.4 aluminum oxide, the diameter of the air resonance device than the 900MHz shown in Fig. 1 is reduced to about 1/3,
About 5.3cm (size B).The defect of this method must be made up of the resonator of the low RF dielectric substances being lost so that should
Resonator is more expensive and is more difficult to manufacture.In addition, most of electric arc 515 of bulb is inside dielectric substance, it is thus impossible to clever
The optical component living being designed in lighting apparatus.By one or more embodiment party for more fully hereinafter describing the present invention
Formula, it has overcome these and other limitations.
Fig. 3 is the simplification figure of the embodiment of compact air resonance device/waveguide of the present invention.The diagram is only example, its
