Description
Technical field
The present invention relates to a kind of lighting source, particularly a kind of plasma area source lamp.
Background technology
Present lighting source kind is a lot, but reason owing to luminescence mechanism, profile almost is spherical or tubular, as incandescent lamp, electrodeless lamp is spherical, fluorescent lamp, electricity-saving lamp is tubular, and the volume that they occupy is big, can't use in some specific occasions, the backlight of liquid crystal for example, the illumination of aircraft handling chamber panel board and some extraordinary panel boards all needs slim lighting source, and it can significantly reduce the thickness and the volume of instrument and equipment, electroluminescent panel (EL), the enamel electroluminescent panel is slim, but brightness is low, photochromic poor, can't be used for illumination, Kai Fa light-emitting diode (LED) lamp brightness in recent years still can, also make area source, but thickness is greater than 15mm.The liquid crystal backlight that presses for slim area source at present adopt the tubule footpath (Φ 2～3mm) glass-tubes make power saving fluorescent lamps up and down two or many be placed on the liquid crystal display screen back and substitute area source lamp, but owing to have distance between the fluorescent tube, luminance difference between the tube and tube in addition, cause the non-uniform light of whole light-emitting area, it is that large-area flat illumination non-uniform light is even more serious for In-particular, they are thin-type light emittings, but are not flat luminous.
Summary of the invention
In order to overcome the deficiency of existing light source, the invention provides a kind of thin plasma area source lamp, this illuminator is slim, and minimum thickness is not more than 4mm, and whole plane is luminous, and brightness is high and even, sends bright white light or other coloured light, and colour temperature can be regulated.
Plasma area source lamp provided by the invention, constitute the area source lamp shell of sealing all around by preceding glass plate, back glass plate, sealing-in limit and blast pipe, electrode in the shell, luminescent material and working gas are formed, be shaped on transparent preceding glass board plane electrode before it is characterized in that on the glass plate, back glass plate is shaped on opaque back glass board plane electrode, all be shaped on transparent dielectric layer on two electrodes, luminescent material fluorescent material is on the transparent dielectric layer of back glass plate.
Glass board plane electrode is prepared from by tin oxide before of the present invention, topped whole preceding glass plate face, and electric conductivity is stable, the transparency height.
Back of the present invention glass board plane electrode adopts metal material to be prepared from, topped whole back glass plate face.
Transparent medium layer material of the present invention is that high lead is glass powder with low melting point.
The working gas that the present invention charges into is three kinds or four kinds of mists of argon, neon, xenon and oxygen, and working gas pressure ratio is: neon Ne 95～98%, xenon Xe 0.6～4% and oxygen O
20.5～1.5% three-element mixed gas body, but also the pressure ratio is: argon Ar 60～65%, neon Ne 32～40%, xenon Xe 0.6～3% and oxygen O
20.5～1.5% quaternary mist.Oxygen O wherein
2Be that to be used to suppress high lead be that dielectric layer decomposes by high-energy ion bombardment the time and causes working gas to change, thereby improve the plasma area source lamp life-span.
The pressure that the present invention charges into working gas is 0.8～0.9 atmospheric pressure.
Luminescent material of the present invention is vacuum uv phosphor (Y, Gd) BO
3: Eu
3+(red), ZnSiO
4: Mn

14O
23: Eu
2+The mixed powder of (orchid) tricolor powder, excitation wavelength are 147nm; Can be a kind of, two or three mixing by a certain percentage in red, green, the blue tricolor powder.
The operation principle of thin plasma area source lamp of the present invention is: when preceding, apply driving voltage on the back plane electrode, make and fill the working gas ionization in the cavity between two glass plates, produce negative ions, form plasma, negative ions under the extra electric field effect respectively to the dielectric layer aggregation of two sides, alternation along with extra electric field, negative ions constantly changes direction, dielectric layer high-speed motion to two sides, in this process, send the vacuum ultraviolet of wavelength 147nm, excitation is coated in red on the glass plate dielectric layer of back, green, blue vacuum uv phosphor, make them luminous, when fluorescent material is red, green, blue three primary colors are mixed by a certain percentage, just send white light; When fluorescent material is that one or both mix by a certain percentage in red, green, the blue three primary colors, just send other different color lights.
The invention has the beneficial effects as follows, 1, luminous be area source, brightness is very even; 2, slim, minimum thickness reaches 3mm, and 3, can realize white-light illuminating, it is easy to change illuminant colour; 4, the life-span is long.
The present invention need to be applied to instrument and meter and many special lightings of slim even lighting source, also can be widely used in plane lamp box advertisement and household lamp decoration etc.
