Description

Lamp electrodeless on both ends
Technical field
The present invention relates to a kind of electric light source, particularly a kind of Non-polarized lamp.
Background technology
Non-polarized lamp is current in the world up-to-date green, energy-conservation, long-life light source, particularly in the Non-polarized lamp of coupling, at present, can only accomplish below the 100w that the lamp of a small amount of 150w is because coupling cavity can't dispel the heat, and cause unstable properties, and the life-span is short, and the lamp more than the 200w is more difficult the manufacturing successfully then; Existing a kind of HF lamp without electrodes, its structure mainly comprises the glass bulb of spherical in shape or pyriform, glass bulb one end caves inward, form the coupling cavity of a single-ended opening, be packaged with indium net and amalgam in the glass bulb, be provided with coupling coil in the coupling cavity, coupling coil installs around the periphery at the magnetic core pipe, one heat conductive rod inserts in the magnetic core pipe from the openend of coupling cavity, and the external part of heat conductive rod is connected with metallic lamp holder; Because it does not have the necessary filament of conventional electric light source or electrode, so claim Non-polarized lamp; Usually the employed operating frequency of low pressure gaseous discharge HF lamp without electrodes is 2.5~3.0MHz, that is to say, the operating frequency of HF lamp without electrodes exceeds 50,000~60,000 times than the operating frequency (50Hz) of the lamp kinds such as ordinary incandescent lamp and inductance type fluorescent lamp used in everyday, Metal halogen lamp, high-pressure sodium lamp, and (30~60KHz) exceed about 250 times than the operating frequency of common energy-saving lamp or electric ballast.It has good energy-saving effect, and is shockproof, and the long-life, without stroboscopic, the advantages such as High Power Factor can be widely used in city illumination, Landscape Lighting, factory, school, various venue, station etc.Its weak point is: during work, easily produce high temperature (100-200 ℃) in the coupling cavity, high temperature can destroy the characteristic of magnetic material, cause the reduction of exciting power, high temperature also can affect the life-span of coupling coil, because heat conductive rod can only be from single-ended with the heat derivation, for the HF lamp without electrodes (20W-100W) of middle low power, can play effective thermolysis, and for more than the 150W HF lamp without electrodes be difficult to accomplish; In addition, high temperature is so that amalgam, fluorescent material all are difficult to bear, and light efficiency can decline to a great extent, colour temperature rises, and the bad change of degradation photoelectric parameter under the color rendering index just because of it is bad to dispel the heat, causes the power of HF lamp without electrodes to be difficult to improve, and generally is limited in below the 200W.
Summary of the invention
The Non-polarized lamp good heat dissipation the purpose of this invention is to provide a kind of lamp electrodeless on both ends, so that can make the above long-time steady operation of fluorescent tube of 200w.
The object of the present invention is achieved like this: lamp electrodeless on both ends, comprise the fluorescent tube that is packaged with indium net and amalgam, and fluorescent tube is provided with coupling cavity, is provided with coupling coil in the coupling cavity, and coupling coil installs around the periphery at the magnetic core pipe, and a heat conducting element is from inserting in the magnetic core pipe; Described coupling cavity runs through fluorescent tube, the coupling cavity two ends are respectively equipped with the lamp holder of tubulose, and the end away from fluorescent tube on the lamp holder is provided with the metal spacer, and described heat conducting element in a tubular form, stretch out from the metal spacer respectively at the heat conducting element two ends, offers louvre on the metal spacer.
The present invention makes fluorescent tube the structure of the coupling cavity that the center band runs through, heat conducting element stretches out from the coupling cavity two ends, so that all can dispel the heat in the two ends of coupling cavity, heat can outwards scatter and disappear through heat conducting element, simultaneously, air and outside air in coupling cavity form convection current through louvre, can play good radiating effect, and fluorescent tube can be made spherical in shape or pyriform; Compared with prior art; heat radiation of the present invention is good; solved bad and the problem that the power HF lamp without electrodes that causes is restricted of coupling cavity heat radiation; can be made into the above high-power high-frequency electrodeless lamp of power 200W; the coupling cavity temperature can drop to about 150 ℃, can effectively protect the three primary colors fluorescent powder of magnetic core pipe, amalgam and coupling cavity light-emitting area, the fluorescent tube of this structure; can break through easily 200w, and can long-time trouble free service.Can be used for the illumination in various places according to the electric light source of the present invention's acquisition.
When the ratio of the intracavity diameter of described heat conducting element and external diameter was 0.3-0.9, above-mentioned ratio was larger, and its circulation of air is better, but metal guide is hot poor; Ratio is less, and its metal guide is hot better, but circulation of air is poor; The intracavity diameter that its best value is heat conducting element is 0.618 with the ratio of external diameter, so that circulation of air and metal guide are hot all relatively good.
