Description
Technical field
The invention belongs to the light source part technical field, be specifically related to a kind of xenon lamp.
Background technology
The principle of luminosity of xenon lamp is a filling inertia chemical gas in the quartzy quartz glass tube of uvioresistant, chemical gas has multiple, wherein major part is inert gases such as xenon (Xenon) and iodide, and then the DC voltage moment about 12V is pressurized to volts up to ten thousand such as 23000V (volt) by booster (Ballast), excite the xenon electronics in the quartz ampoule free through the high pressure amplitude of vibration, between the two poles of the earth, produce light source, Here it is the alleged gas discharge of people.Because the white superpower arclight that xenon produced can improve the light color temperature value, show sunshine as daytime, again, required current potential only is about 3.5A during xenon lamp work, and brightness is 3 times of traditional based on halogen bulb, and service life is longer more than 10 times than traditional based on halogen bulb, therefore is subjected to thinking highly of of people.For example,, therefore very help enlarging the visual range in car the place ahead, build safer riving condition because it has remarkable energy density and intensity of illumination when this lamp is installed on the automobile.Again,, thereby can not occur that the such tungsten filament of daily being seen incandescent lamp blows and the problem of scrapping, and in case break down, xenon lamp can not extinguish moment, but extinguish or light fast by the mode of deepening gradually because there is not filament in xenon lamp.Also, xenon lamp can not produce unnecessary dazzle, can not cause interference to head-on sending a car.Certainly, the application scenario of xenon lamp is not limited to aforesaid automobile, more properly say the restriction that does not have use occasion, for example the pixel element of digital micro-mirror device (Digital Micro-mirror Device＜abbreviation DMD 〉) or liquid-crystal apparatus etc. is carried out illumination and penetrates and amplify projection by high power light source, thus on screen the projection map.
About the technical information of xenon lamp, in China and foreign countries' patent documentation, all can be seen in a large number, foreign patent Japan is more, slightly with exemplify as TOHKEMY 2004-134104, the flat 8-096751 of TOHKEMY and the flat 11-096970 of TOHKEMY.Shine xenon lamp before China utility model patent Granted publication CN201093285Y has introduced a kind of automobile, this scheme has been done improvement to fluorescent tube (patent claims bulb) and lamp socket.CN2568943Y has recommended a kind of automobile-used super-pressure xenon lamp, and characteristics are that protective cover is set above lamp socket.CN201377771Y provides a kind of vehicle xenon lamp, fixes the effect that combines that a stainless steel improves lamp body and lamp socket by the lamp socket upper surface.Also have CN2760751Y, CN1333427C, CN10154787A and CN101699161A or the like all to relate to xenon lamp in addition.
The above-mentioned related xenon lamp of patented technology scheme that exemplifies has common design feature, promptly, discharge type must be two-way exchange when work, otherwise can produce serious light deletes, therefore rectifier can only adopt AC adapter, and the price of AC adapter is more usually, xenon lamp with 35W is an example, present price is about more than 60 yuan (RMB), not only causes user cost to increase thus, and the waste resource, because AC adapter is for dc rectifier, parts are many, make trouble, and assemble loaded down with trivial details.
In fact, comprise all a large amount of productions of automobile production industry or use the manufacturer of xenon lamp all to recognize the described shortcoming of applicant to some extent in the above, only be not find the technical scheme that is remedied above-mentioned shortcoming, still do not have the plan of reply though that is to say the heart of improvement.The applicant thinks that reason has two, one, and from objective, it is saturated that the structure of xenon lamp is tending towards substantially, is difficult to the space of breakthrough; The 2nd, from subjective, worry can not be accepted by the public because of structure produces excessive variation, promptly be in fear of contrary many.For this reason, the applicant has carried out positive and careful exploration, concrete structure is done excessive variation and can be obtained beyond thought technique effect and overcome and find equalization point between the aforementioned technical problem need not, technical scheme described below is based on producing under this prerequisite.
Summary of the invention
Task of the present invention be to provide a kind of when work discharge type need not two-way exchange and can also ensure effectively that light is deleted not reduce and use the xenon lamp that alleviates as the use cost of the rectifier of distribution power supply.
Task of the present invention is finished like this, a kind of xenon lamp, comprise lamp body and lamp socket, lamp body and lamp socket are fixed, lamp body comprises the cover plate pipe, glass core pipe and the moon, positive wire, cover plate pipe and described lamp socket are fixed, the glass core pipe is located in the cover plate pipe, this glass core pipe is by having discharge cavity and be filled with the discharge pipeline section of xenon in discharge cavity, the first core pipe pipeline section and the second core pipe pipeline section constitute, the first core pipe pipeline section is made of continuous extension of an end of described discharge pipeline section, and the second core pipe pipeline section connect to be extended by the other end of discharge pipeline section and constitutes, border on the position at the first core pipe pipeline section with the discharge pipeline section and constitute narrow first neck that contracts, and the junction of the second core pipe pipeline section and discharge pipeline section constitutes narrow second neck that contracts, one end of cathode wire is positioned at the described first core pipe pipeline section and probes into described discharge cavity, it is outer and is being connected the lead connection with negative electrode on the lamp socket on the described lamp socket that the other end is stretched over the first core pipe pipeline section, one end of positive wire is positioned at the described second core pipe pipeline section and probes into described discharge cavity, corresponding with the described cathode wire that is insinuated in the discharge cavity, it is outer and is being connected the lead connection with anode on the lamp socket on the described lamp socket that the other end of positive wire is stretched over the second core pipe pipeline section, be characterised in that: on the outer wall of described first neck, be combined with reflectance coating, and reflectance coating also extends to the core pipe pipe shoulder of the first core pipe pipeline section and extends to the discharge pipeline section pipe shoulder of described discharge pipeline section.
In a specific embodiment of the present invention, described reflectance coating is a pellumina, and thickness is 10-20 μ m.
