Embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
The utility model embodiment provides a kind of electrodeless bulb, as shown in Figure 1 to Figure 3, mainly comprises: quartz bulb shell 11; In quartz bulb shell 11, be filled with inert gas, mercury and halide, wherein inert gas, mercury and the halide of quartz bulb shell 11 interior fillings all do not draw; Quartz bulb shell 11 is ellipsoid shape, passes the tangent plane ovalize of the axis of quartz bulb shell 11, and the length of this oval-shaped major diameter is the twice of minor axis length; On quartz bulb shell 11, be provided with the connecting portion 12 being connected for the bulb installation seat 211 with on microwave resonance device 2.
Discharge gas in the utility model embodiment in the quartz bulb shell 11 of electrodeless bulb 1 is set to inert gas, mercury and halide, simultaneously by making the operating power of electrodeless bulb 1 between 15W～150W to the design of quartz bulb shell 11 shapes, size, make electrodeless bulb 1 can be used in indoor general lighting, overcome thus and in correlation technique, do not had power technical problem for the Non-polarized lamp of indoor general lighting between 15W～150W.
In the process of electrodeless bulb 1 that is designed for indoor general lighting, the kind of the material of filling in the shape of cell-shell, cell-shell, the parameters such as useful life, luminous efficiency and color rendering index that content all can affect the electrodeless bulb 1 of making, for making useful life, luminous efficiency and the color rendering index of the electrodeless bulb 1 of design more meet user demand, in the utility model embodiment, further the structure of electrodeless bulb 1 is optimized to design.
Particularly, the wall thickness of quartz bulb shell 11 is 0.5～1.5 millimeter, for example, the wall thickness of quartz bulb shell 11 is designed to 0.5 millimeter, 0.6 millimeter, 0.7 millimeter, 0.8 millimeter, 0.9 millimeter, 1.0 millimeters, 1.1 millimeters, 1.2 millimeters, 1.3 millimeters, 1.4 millimeters and 1.5 millimeters.
When the size of design quartz bulb shell 11, can be according to for being set, the size of the base of bulb installation seat 211 designing of arranging on microwave resonance device 2, and preferably, the size of quartz bulb shell 11 is mated with the size of base.
Further, for the base of bulb installation seat 211 is set, have rectangle installed surface, the length of side of described rectangle installed surface matches with the minor axis of the oval tangent plane through axis of quartz bulb shell 11.
As shown in Figure 1, the connecting portion 12 on quartz bulb shell 11 is extended to form by quartz bulb shell 11, and connecting portion 12 is arranged at an end of quartz bulb shell 11.
Further, the interior mercury of can filling of quartz bulb shell 11 also can not filled mercury.While being filled with mercury in quartz bulb shell 11, it exists as buffer gas, and it is liquid at normal temperatures, has lower vapour pressure, and puncturing of Non-polarized lamp had no significant effect; And at high temperature it is gaseous state, can meet the needs of Non-polarized lamp when steady operation.Mercury discharges in the startup stage participation of Non-polarized lamp; After lamp steady lighting point, it does not participate in electric discharge substantially, just as slowing down the cushion of electron motion to tube wall loss, exists.Under the condition without mercury, although simple, to fill more anticyclonic rare gas and also can make bulb light and work, the efficiency of Non-polarized lamp is generally lower.This is because the electromagnetic field that coupled micro-cavity imports is difficult to by plasma absorption.But for the bulb of certain power, certain size, the charge of mercury also has optimum value.Experimental result shows that the loading of mercury is that every cubic millimeter of 0.01～0.03 milligram hour is comparatively suitable.
Non-polarized lamp startup stage, because temperature in bulb is lower, the vapour pressure of mercury is very low, if there is no the help of rare gas, external electromagnetic field is difficult to excite electric discharge in bulb.Rare gas startup stage played the part of the role of buffer gas, can help discharge plasma to puncture and further absorb energy.Once discharge breakdown, along with the continuous rising of temperature, the mercury vapor pressure in lamp starts continuous rising, and rare gas is slowly no longer played the part of the role of buffer gas.After bulb steady operation, near bulb wall, rare-gas atom and mercury atom bump, can slow down mercury atom and collide the energy loss that bulb wall is brought, rare gas is the discharge plasma insulation in bulb as cotton-wadded quilt, makes it maintain optimum temperature.The rare gas that atomic weight is larger, its heat insulation effect is also better.
Particularly, the inert gas in quartz bulb shell 11 can be argon gas, Krypton, and one or more in xenon, preferably, the inert gas in quartz bulb shell 11 comprises xenon, and/or, argon gas.In addition, the pressure of quartz bulb shell 11 interior inert gases is 10～40 holders.
The halide of quartz bulb shell 11 interior fillings is main luminescent substance, halid kind and quantity have determined the main performance of electrodeless bulb 1, particularly, the halide of electrodeless bulb 1 interior filling can be InBr3, InBr, InI3, InI, Na-Tl-In series metal halide pill and Sc-Na series metal halide pill.
Preferably, the halide in quartz bulb shell 11 is Na-Tl-In series metal halide pill.
Halid loading in quartz bulb shell 11 is every cubic millimeter of 0.0005～0.0015 milligram hour in addition, be conducive to improve the luminous efficiency of electrodeless bulb 1, especially the Na-Tl-In series metal halide pill that the interior filling colour temperature of quartz bulb shell 11 is 4000K, loading is that every cubic millimeter of 0.0005～0.0015 milligram of luminous efficiency is better.
The utility model embodiment also provides a kind of lighting apparatus, as shown in Figures 2 and 3, comprising: above-mentioned electrodeless bulb 1 and microwave resonance device 2; The connecting portion 12 of electrodeless bulb 1 is connected with the bulb installation seat 211 of microwave resonance device 2.
As shown in Figure 3, microwave cavity 2a comprises: stepped hollow metal cylindrical shell 22, annular top cover 221 and annular bottom 222; In shell 22, be provided with staged Metallic rod 21, Metallic rod 21 is coaxial with shell 22; Between Metallic rod 21 and shell 22, be filled with heat sink material; The opening of the opening of annular top cover 221 and annular bottom 222 is top and the bottom of corresponding Metallic rod 21 respectively, and the top of Metallic rod 21 is provided with for connecting the bulb installation seat 211 of electrodeless bulb 1; The bottom of Metallic rod 21 is provided with the contact 212 that connects microwave connector 2b.
