Description
Invention field
The present invention relates to lamp, more specifically, is a kind of lighting device that adopts suitable phosphorus to combine with the cold-cathode field emitter.This invention is the product (patent No. W-7405-ENG-36) that combines with Ministry of Energy.
Background of invention
Fluorescent lamp is the lighting system of standard in the commercial building always for many years, but less in the family application.Generally when needing economic illumination, large space just adopts it.Though tungsten lamp is compared with fluorescent lamp, efficient is low and expensive, because it is easy to use and reliable, be still the main mode of domestic lighting.
Though fluorescent lamp is a kind of lighting system with greater efficiency, it truly have many weak points, these weak points are related to ecological aspect.Fluorescent tube is classified as harmful substance by EPA (EPA) at present, because it contains restricted material mercury huge poison, strict.This problem has caused the generation of No. 5229686 and No. 5229687 patents of the U.S., and they have described in the fluorescent lamp mercury can filtrable problem and add chemical reagent in fluorescent tube, when fluorescent tube is broken, these reagent just with mercury generation chemical reaction.But, in most of the cases need the ballast resistor, otherwise fluorescent lamp series containing polychlorinated biphenyl base oil (PCB), this oil also is the height carcinogen of EPA restriction.
Usually fluorescent tube needs many operations.At first the liquid mercury in the pipe is carried out electric heating, part mercury is evaporated, thereby make electric current excite mercury to enter plasmoid then by mercury vapour, the mercury plasma that is excited sends ultraviolet, phosphorus in the last ultraviolet irradiation fluorescent tube, phosphorus becomes visible light with the ultraviolet light power conversion and launches.The method of this generation light has weak point.Compare with common incandescent tungsten lamp, because mercury must be heated to form mercury vapour, fluorescent lamp starting is slow.And because well-known converter noise needs to start ballast and deposit electronics, and holding current passes through mercury vapour.When fluorescent lamp is colder, and open for the first time, the situation of optical flare can occur, therefore can attract people's attentiveness.Though and fluorescent lamp is incompatible with low light level technology commonly used, this low light level technology need be used the low light level fluorescent lamp of the costliness of higher external power usually for the output intensity of regulating light.
I.Brodie is disclosed a kind of lamp in U.S.4818914, comprises a negative electrode that is made of the prong array-as tissue, an accelerating electrode that is made of array of orifices, the cover layer of a phosphorus and an anode of protruding on a surface.Voltage is added between negative electrode and the intensifying ring, also is added between negative electrode and the anode simultaneously, causes collecting electronics at the cathode emission electronics at anode.Electron collision phosphorus cover layer sends light.Dworsky etc. disclose uniform source of light in U.S.5180951, be a high crystal diamond wafers electronic emitter basically.The light source of people such as Y-Taniguichi disclosed a kind of fluorescent tube in WO 94/28571 comprises that the noncrystal diamond wafers of one deck is placed on the conduction filament, one swathe on filament anode and by emitting electrons collision and luminous thin slice.Noncrystal diamond wafers has constituted many distributed fixedly electron emission regions, and each subregion is divided into the zonule by different characteristic electrons.
The purpose of this invention is to provide a non-mercury florescent lamp that adopts fibrous field emission unit.
Another object of the present invention provides a fluorescent lamp of moment unlatching basically.
Another object of the present invention provides the back of the body formula lamp of a low voltage and low power.
Summary of the invention
In order to achieve the above object, in conjunction with purpose of the present invention, here embodiments of the invention are described widely.The invention provides a kind of lighting device, comprise a kind of fiber cold cathode electronic generator, here said cold cathode fiber has the diameter less than 100 microns, a kind of and the interactional anode of fiber cold-cathode emitters electrons emitted, a kind of can the interaction and the phosphorus of generation lasting light with the cold-cathode emitters electrons emitted, a kind of less than 10

Describe in detail
Field emission illumination device and fiber field emission illumination device (FFEL) have been the present invention relates to.
What lighting device of the present invention used is the field emission that produces light from phosphorus, i.e. cathodoluminescence material.
This field emission illumination device comprises a fiber cold-cathode field reflector.The field emission electron emissive material can be provided by any fiber-based material.Preferably field emission electron emission fiber material is diamond, diamond-like-carbon or vitreous carbon, and diamond is preferred especially person.Most preferably, the fiber negative electrode is by one or more diamond, diamond-like-carbon or vitreous carbon synthetic fibers.Diamond, diamond-like-carbon or vitreous carbon basic comprising the core fiber of non-diamond.The non-diamond core can be made up of conductor or semi-conducting material.A kind of selection, core can be made by non-conductive material, is swathed by conductor or semiconductor material thin film cover again.That is, the core material in the diamond fiber can be conductor carbon, as graphite or metal, as tungsten, promptly also can be silicon, copper, molybdenum, titanium or silicon carbide.Another embodiment is to be made up of uncomplicated structure, as the non-conductive material that swathes with conductor or semiconductor material thin film cover, and diamond, diamond-like-carbon or glassy carbon layer are enclosed on the cover.For example, the non-conductor core can be to resemble nylon, KEVLAR
(KEVLAR
Registered in E.I.dupontde Nomours and Company, Wilmington.DE market) so artificial manufacturing fiber, or polyamides, inorganic material, as pottery or glass.Another embodiment is, the early production of diamond, diamond-like-carbon or vitreous carbon can be enclosed within on the non-diamond core, perhaps, core can be diamond, diamond-like-carbon or vitreous carbon early production, and diamond, diamond-like-carbon or vitreous carbon also can be formed by the suitable processing method of early production.
Especially, the field emission illumination device comprises a fiber cold-cathode field reflector, this reflector U.S. Valone on February 14th, 1994 applied for 08/196, describe to some extent in No. 343 patents, patent name is " diamond-graphite field emission device ", or describes to some extent in 08/387, No. 539 patent that U.S. Blanchet-Fincher applies on February nineteen ninety-five 13, patent name is " a diamond fiber field emission device ", and description like this is hereby incorporated by.In addition, the cold-cathode field reflector also can be any other suitable emission fiber material, for example, come the suitable graphite fibre after the exposure-processed or apply for a patent 60/002 with strong ion by what the Friedman of the U.S. proposed, describe in 277 handle with laser explosure after suitable graphite fibre, 60/002, No. 277 patent was applied in August 14 nineteen ninety-five, title is " production method of the transmitting site in control field ", perhaps diamond cover, diamond like carbon neck cover LEVLAR
Fiber, this fiber is described in 08/387, No. 539 patent of U.S.'s application in 13 days February nineteen ninety-five to some extent; Or contain the fiber of vitreous carbon, one is presented on about 1380～1598cm
-1Amorphous materials of Raman peak value or the like.Here " diamond-like-carbon " title that is adopted is meant diamond like carbon material with carbon element, vitreous carbon, contains the carbon of atomic little vitreous carbon composition.All above materials its performance as field emmision material the time is all similar to diamond-like-carbon.
