Abstract

The utility model provides a miniature, high-efficiency and high-performance dual-end xenon metal halide lamp. Ceramic with high-pressure resistance is taken to make a lamp cap and a lamp holder; favorable isolation measures are taken to thoroughly avoid space breakdown and surface creepage and to prevent strong electric fields appearing in down-leads and insulating mediums because of regular ignition from resulting in bad results of aging, insulating performance descent, etc. The utility model has the advantages of stable performance and long service life, and can be used for special illumination and commercial illumination.

Description

A kind of miniature, efficient both-end Xenon gas metallic halogen lamp

Technical field:

The utility model relates to a kind of miniature small-power, the efficient little both-end Metal halogen lamp of luminous point, especially a kind of high performance both-end Xenon gas metallic halogen lamp that is used for special lighting and commercial lighting.

Background technology:

The small-power Metal halogen lamp is used comparatively universal, but particularly the following Metal halogen lamp volume of 50W is big, quality is low for current small-power Metal halogen lamp, poor stability, the property of loosing is big in addition, focusing performance poor (electric arc long) particularly the life-span shorter, light decay and look drift are serious, and have limited its use greatly.

Summary of the invention:

The purpose of this utility model provides a kind of prior art shortcoming that overcomes, efficient, energy-conservation, volume is little, stability is high, acnode is little, the life-span is long, can the instantaneous high-performance special lighting Xenon gas metallic halogen lamp of lighting.

The utility model can adopt the xenon metal halogen lamp bulb of the disclosed structure of Chinese patent ZL200320117733.0 or common on the market straight tube shape xenon metal halogen lamp bulb, be provided with spheroidal or ellipsoid shape in this bulb and be filled with the electric arc tube of ionisable substance, the electric arc tube two ends are respectively equipped with diameter contraction that is mutually 180 degree angles and the neck body that seals, electric arc tube is outer and be encapsulated with outer casing, and first electrode in the electric arc tube, second electrode are respectively by being connected to form the both-end Xenon gas metallic halogen lamp with the ceramic lamp base that has the copper heart outside electric conductor in the corresponding end neck body and the protruded tube.Be filled with 6 atmospheric xenons in the electric arc tube, interelectrode distance especially only is 4.2mm or littler less than 5mm, and this lamp requires to have the high voltage pulse puncture of 23KV and can reach nominal brightness and the logical output of light in the several seconds.Produce the high electric field pulse of 23KV during owing to light a lamp, so the utility model has adopted high voltage bearing ceramic making lamp holder, lamp socket, and good shielding quarantine measures have been adopted, as adopt and isolate potsherd 8b and silicon rubber etc. thoroughly to avoid space puncture and the surface creepage phenomenon between lamp holder and the lamp socket steelframe, at the fixing hole middle cover of the spring leaf of the contact-carrying of lamp socket and porcelain seat with potsherd 8a and poured into insulating cement, to prevent degradation adverse consequences under the discharge performance that passes through fixing steelframe between the electrode.

The utility model is owing to taked above structure, so can solve space puncture and surface creepage problem that the high voltage pulse discharge brings well, also prevent the adverse consequencess such as aging and decreasing insulating that cause because of frequent highfield of lighting a fire frequent appearance between lead-in wire and the dielectric simultaneously.Therefore, the utility model is energy-efficient, and volume is little far beyond conventional Metal halogen lamp, can reach nominal brightness in several seconds after lighting, running is stable, and the life-span is long, color rendering index Metal halogen lamp height also commonly used, this type of light source interelectrode distance is at 4.2mm or following in addition, even can accomplish below the 2mm, near the representative point light source, be easy to design lamps, and obtain needed ideal focusing light beam, be used in various to the exigent special occasions that throws light on, as various special lightings and high-quality commercial lighting.

Description of reference numerals:

Xenon metal halogen lamp bulb 1, both-end biquartz Metal halogen lamp 2, both-end lamp socket 3, lamp holder 4 (4a, 4b), the ceramic component 5 of lamp socket (5a, 5b) has the lead-in wire and the spring leaf 6 (6a, 6b) of contact point on the lamp socket, lamp socket is steelframe 7 fixedly, and high pressure isolation potsherd 8 (8a, 8b)

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples:

Embodiment one:

See Fig. 1～shown in Figure 9, present embodiment includes the xenon metal halogen lamp bulb 1 of the disclosed structure of an employing Chinese patent ZL200320117733.0, interelectrode distance is 4.2mm, its two end contracts to seal and receives the thin ceramic lamp base 4a that also respectively puts, 4b, and electrode outlet line is crimped on copper draws in the cap, make both-end biquartz Metal halogen lamp 2.Spring leaf 6a, the 6b that will have two leads and contact then are fixed on two ceramics seat 5a,, on the 5b again riveting, then be assembled into both-end lamp socket 3, and both-end biquartz Metal halogen lamp 2 inserted in the seat fixedly on the steelframe 7 at the lamp socket of fixed lamp-socket.

Can be filled with 6 atmospheric xenons in the lamp 2, high-pressure xenon can guarantee that lamp lights the back and promptly enter the normal illumination state in the several seconds; Because this type of light source needs very high voltage starting (23KV), very high to insulating requirements, therefore taking special measure for example in ceramics seat and the lamp socket rivet apertura lateralis that fixedly steelframe 7 is fixed, to be added with silica gel and ceramics 8b aspect the lamp socket designs, and in the hole of porcelain seat 5a, 5b and lead-in wire spring leaf riveted also envelope silica gel and ceramics 8a are arranged, thereby the discharge of two electrodes that cut off lamp by the stainless steel stent plate or creepage.

Because the working temperature of lamp is very high, so adopted the Ceramic lamp base 5a, the 5b that bear high temperature, high voltage impact shown in Figure 4, and height insulate, ceramic lamp base 4a, the 4b of high heat-proof quality, and pours into insulating cement and intercept potsherd 8 at spring leaf 6a, the 6b rivet of contact-carrying.

Present embodiment is the xenon metal halide lamp of 20W---100W applicable to lamp power.
