Abstract
The utility model aims to provide a low-cost bulb of a high frequency electrodeless lamp. The bulb has a large coupling area formed by a coupler and a discharging space. The bulb comprises a bulb glass envelope and a coupler, wherein the coupler is disposed in the bulb glass envelope, the coupler comprises a high frequency magnetic core with a ring-shaped opening, a high frequency coil and a coupling glass envelope with a ring-shaped opening, and the coupling glass envelope encircles the high frequency magnetic core and the high frequency coil. In the bulb of the high frequency electrodeless lamp, because the coupler encircles the coupling glass envelope and is directly disposed in the bulb glass envelope, so a central cavity is not needed to be prepared in the bulb glass envelope, and cost is substantially reduced. Besides, the coupling area formed by the coupler and the discharging space is enlarged, and conversion efficiency is improved.
Description
Technical field
The utility model relates to a kind of lighting, especially a kind of HF lamp without electrodes bulb.
Background technology
HF lamp without electrodes is with its high light efficiency, and high-color rendering starts soon, and the life-span is long, and is energy-conservation, and advantages such as environmental protection are used widely.Existing HF lamp without electrodes is by high frequency power generator, power coupler and electrodeless lamp bulb are formed, the high-frequency current that the energising back is produced by high frequency electric source, produce the power electromagnet field through the power coupler induction coil, inductive coupling is to the bulb glass center cavity, make the ionized inert gas in the bulb glass, produce ultraviolet impact fluorescence gas luminescence.
Existing HF lamp without electrodes bulb is placed coupler because bulb glass need be made center cavity, and cost improves greatly, and coupler and discharge space coupling area are little, and efficient is lower.
The utility model content
It is low that the purpose of this utility model provides a kind of cost, the HF lamp without electrodes bulb that coupler and discharge space coupling area are big.
Realize the HF lamp without electrodes bulb of the utility model purpose, comprise bulb glass and coupler, described coupler is placed in the bulb glass, described coupler comprises open circles annular high frequency magnetic core, high frequency coil and open circles annular coupling glass bulb, described coupling glass bulb surrounds described high frequency magnetic core and high frequency coil.
The openend of described high frequency magnetic core up.
The extended distance of described high frequency magnetic core be the high frequency magnetic core diameter 1/4～1/2 between.
Scribble three-color phosphor on the outer wall of the inwall of described bulb glass and coupling glass bulb.
The beneficial effects of the utility model are as follows:
1, HF lamp without electrodes bulb of the present utility model directly is placed in the bulb glass because coupler is surrounded the coupling glass bulb, needn't make center cavity again in bulb glass, and cost reduces greatly; Also improve the coupling area of coupler and discharge space, improved transformation efficiency greatly.
2, HF lamp without electrodes bulb of the present utility model, because high frequency magnetic core is the annular of opening, the opening part high frequency magnetic line of force at high frequency magnetic core is intensive, the high-frequency induction electric field is the strongest, can use lower keep-alive voltage HF lamp without electrodes can be lighted discharge, save burning time, reduced keep-alive voltage.
Description of drawings
Fig. 1 is the structural representation of the utility model HF lamp without electrodes bulb.
Embodiment
Embodiment of the present utility model is as follows:
As shown in Figure 1, HF lamp without electrodes bulb of the present utility model, comprise bulb glass 1 and coupler, described coupler is placed in the bulb glass 1, described coupler comprises open circles annular high frequency magnetic core 4, high frequency coil 5 and open circles annular coupling glass bulb 3, and described coupling glass bulb 3 surrounds described high frequency magnetic core 4 and high frequency coil 5, the openend of described high frequency magnetic core 4 up, extended distance be high frequency magnetic core 4 diameters 1/4～1/2 between.
HF lamp without electrodes bulb of the present utility model directly is placed in the bulb glass because coupler is surrounded the coupling glass bulb, needn't make center cavity again in bulb glass, and cost reduces greatly; Also improve the coupling area of coupler and discharge space, improved transformation efficiency greatly.
Scribble three-color phosphor 2 on the outer wall of the inwall of described bulb glass 1 and coupling glass bulb 3.Also be provided with auxiliary mercurial 11 in the bulb glass 1, getter 12, working gas 13, high frequency coil 5 links to each other with lead 6, and interior lines line 6 links to each other with lead-out wire 9, and the bulb glass lower end is provided with stem stem body 7, the surplus tail 8 of blast pipe is housed on the stem stem body 7, scribbles main mercurial 10 on the surplus tail 8 of blast pipe.
HF lamp without electrodes bulb of the present utility model, because high frequency magnetic core is the annular of opening, the opening part high frequency magnetic line of force at high frequency magnetic core is intensive, the high-frequency induction electric field is the strongest, can use lower keep-alive voltage HF lamp without electrodes can be lighted discharge, save burning time, reduced keep-alive voltage.
