Abstract
The utility model relates to a novel ceramic lamp which comprises a ceramic electrode and a discharge container; the lower part of the discharge container is a cup-shaped lamp holder, and the upper part of the discharge container is a column-shaped glass seal tube; the whole discharge container rotates and is symmetric along a central axis, and inert gas is fully filled in the discharge container; the ceramic electrode is arranged on the cup-shaped lamp holder; in the ceramic electrode, a niobium tungsten alloy serves as a main rod, the middle part of the ceramic electrode is wrapped by ceramic body; and a yttrium molybdenum alloy wire spiral body is wound around the lower part of the ceramic body, a high-purity tungsten wire spiral body is adopted as part upper part of the ceramic body, and the head of the high-purity tungsten wire spiral body is arranged in a discharge cavity which contains a discharge medium. The novel ceramic lamp can be widely applied to commercial and daily lighting, and has the advantages of high efficiency, safety and long service life.
Description
Technical field
The utility model relates to the normal lighting field, is specially a kind of new ceramics lamp that possesses high light efficiency, low energy consumption.
Background technology
In the today of being becoming tight energy day, growing along with lighting technology, high light efficiency, high-color rendering, long-life electric light source products is increasing to receive pursuing and paying close attention to of market.Ceramic gold-halogen lamp is development and come on the basis of traditional quartz metal halide lamp and high-pressure sodium lamp; Advantage with high light efficiency, high-color rendering; But this modulated structure makes its manufacturing cost high at the requirement height very of raw material and each link of processing.
Simultaneously; Conventional ceramic Metal halogen lamp sealing-in effect on the market is general; The unreasonable inequality of being heated that causes of lamp inner structure, and lamp body all will through the physical process of expanding with heat and contract with cold in each switching process, make this ceramic gold-halogen lamp after the long period use; Electrode is prone to be corroded and causes electrode surface embrittlement to lose efficacy, and has reduced useful life.
The utility model content
The technical problem that the utility model solved is to provide a kind of new ceramics lamp, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of new ceramics lamp comprises ceramic electrode and discharge vessel, and wherein, the discharge vessel bottom is the cup-shaped lamp socket, and top is cylindricality glass capsulation pipe, and whole discharge vessel is about central axis rotation symmetry, and inside is full of inert gas; Ceramic electrode then is installed on the cup-shaped lamp socket; Said ceramic electrode is a mobile jib with the niobium tungsten alloy; Wrap up with ceramic body the mid portion position; Ceramic body part below installs around yttrium molybdenum alloy thread helicoid, and ceramic body part top is high-purity tungsten filament helicoid, and the spirochetal head of high-purity tungsten filament is positioned at the discharge cavity that contains discharge medium.
In the utility model, said discharge cavity is the ball cavity configuration in the discharge vessel, can be one-body molded with the cylindricality glass capsulation pipe of discharge vessel, also can be installed on the cup-shaped lamp socket through pole.
In the utility model, should comprise an optics cambered surface on the inner surface at the top of said cylindricality glass capsulation pipe and the outer surface at least, and the focus of the center position of discharge cavity, optics cambered surface should be positioned on the central symmetry axes all.
In the utility model, the ceramic body length on the niobium tungsten alloy mobile jib should not surpass 1/3 of mobile jib.
Beneficial effect: the utility model has effectively been controlled the space of cold junction.Photochromic consistency has been played good guarantee effect, and yttrium molybdenum alloy thread helicoid and ceramic layer can effectively relax the thermal shock of high electric current to fluorescent tube, high-purity tungsten filament helicoid also can effectively reduce power consumption in the discharge cavity discharge on discharge vessel top.Therefore, the utility model has well solved the sealing-in problem of conventional ceramic Metal halogen lamp, will play enormous function to quality and the performance that improves ceramic lamp.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of new ceramics lamp of Fig. 1; In the present embodiment; Discharge vessel top is cylindricality glass capsulation pipe 1, and glass capsulation pipe 1 inboard is an optical surface, and niobium tungsten alloy mobile jib 3 tops in the inner-cavity structure of glass capsulation pipe 1 are high-purity tungsten filament helicoid 4; The bottom is a yttrium molybdenum alloy thread helicoid 7, and the ceramic inclusion enclave 6 that cylindricality is set between high-purity tungsten filament helicoid 4 and the yttrium molybdenum alloy thread helicoid 7 carries out excessively.
Simultaneously, in the present embodiment, high-purity tungsten filament helicoid 4 tips are arranged in ball-type discharge cavity 2, and ball-type discharge cavity 2 then is installed on the cup-shaped lamp socket 8 through pole support.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
