Description

A kind of short-arc lamp electrode
Technical field
The utility model relates to a kind of short-arc lamp electrode.
Background technology
Short-arc lamp is due to its high brightness, specular removal, long-life and as comparatively ideal special source, be applied to various exposure/projection arrangement.But, in the manufacturing process of lamp, find, ensure the high light intensity performance of lamp parameter and in a modulate state in steady operation and long-life general requirement, each factor is conflicting.As for ensureing that luminous element has high brightness, just require the electric discharge end of negative electrode to make sharp shape, anode-cathode distance is little simultaneously, and meanwhile, the scaling loss due to electrode can make again the lost of life waited.Therefore, the high and long-life electrode of the high light intensity simultaneously of research and development stability is the main target of research staff.
One " discharge lamp " is disclosed in prior art, publication number is 101271819, publication date is the Japan Patent of 20080924, disclose a kind of discharge lamp, the anode surface of discharge lamp is provided with radiator structure to increase the surface area of anode, this radiator structure is made up of multiple parallel slots of the ring-type perpendicular with axle, and the sectional area of groove is V-shaped and has stair-stepping side.The structure of this patent Anodic can the intensity of radiator structure of holding electrode, and improve radiating effect simultaneously, but because it considers heat dissipation problem, and when lamp starts the most advanced and sophisticated heat of easy dispersive electrode, consume energy.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of electrode, can improve the emission effciency of electrode, and the heat of eletrode tip is more effectively used.
The utility model solves the problems referred to above by the following technical programs: a kind of short-arc lamp electrode, the negative electrode of described short-arc lamp electrode comprises a columniform arcing body, the front end of described arcing body is provided with protuberance, and the connecting portion of described protuberance and described arcing body is provided with recess.
Preferably, described recess is set to annular recess.
Preferably, the cross section of described recess is V-arrangement or U-shaped.
Preferably, described recess presents at least two steps.
Preferably, the degree of depth of described recess is 0.2mm ~ 1mm.
Preferably, the surface of described recess is provided with cutting.
Preferably, described cutting is parallel with recess cross section.
Preferably, described cutting is along one end of recess to the other end longitudinal arrangement of recess.
Preferably, described cutting is set to irregularly shaped.
Positive progressive effect of the present utility model is: a kind of short-arc lamp electrode, and described negative electrode comprises a columniform arcing body, and the front end of described arcing body is provided with protuberance, and the connecting portion of described protuberance and described arcing body is provided with recess.By the recess that the protuberance of the utility model short-arc lamp electrode and the connecting portion of arcing body are arranged, making short-arc lamp when starting, heat can be made effectively to concentrate on arcing body protrusion, reduce the speed of heat to arcing body tail transfer, improve emission effciency, reduce the starting resistor of lamp.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1:
As shown in Figure 1, a kind of short-arc lamp electrode, the negative electrode of short-arc lamp electrode comprises a columniform arcing body, and the front end of arcing body is provided with protuberance, and the connecting portion of protuberance and described arcing body is provided with recess.Be provided with recess, when short-arc lamp starts, heat can be made effectively to concentrate on arcing body protrusion, reduce the speed of heat to arcing body tail transfer, improve emission effciency, reduce the starting resistor of lamp.
Further, recess is set to annular recess.
Further, the cross section of recess is V-arrangement or U-shaped.
Further, as Fig. 2, recess presents the even multiple step of at least two steps.
Further, the degree of depth of recess is 0.2mm ~ 1mm.
Embodiment 2:
On the basis of embodiment 1, the surface of recess is provided with cutting.After lamp starts, its arcing body protrusion needs heat radiation, and be provided with cutting, add the surface area of electrode, its area of dissipation also increases, and radiating rate is fast, inhibits electrode to evaporate too fast problem, and then improves the life-span of lamp.Meanwhile, arrange recess and cutting, the speed making heat be delivered to electrode afterbody from arcing body protrusion reduces, heat is made to concentrate on arcing body most advanced and sophisticated, tip temperature rises very fast, improves the emission effciency at negative electrode arcing body tip, thus can lower the starting resistor of lamp.
Further, as Fig. 3, cutting can be set to transversely arranged mode, parallel with recess cross section, also can as the mode of Fig. 4, cutting, also can in the mode of Fig. 5 along one end of recess to the other end longitudinal arrangement of recess, cutting is engraved on step, also cutting can be set to other shape.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
