Abstract
The invention relates to the illumination field, in particular to a halogen-free fluorescent lamp. The technical proposal is as follows: the fluorescent lamp comprises a glass tube, lamp caps on two ends of the glass tube, a core column, an electrode sealed in the glass tube and neon, wherein fluorescent powder mainly containing magnesium europium fluogermanate and magnesium arsenate is coated on the inner wall of the glass tube, with 30 to 50 percent of the magnesium europium fluogermanate and 49 to 69 percent of the magnesium arsenate by mass percentage. The technical proposal is adopted to obtain the decorative fluorescent lamp emitting red visible light, does not use halogen raw material to prevent environmental pollution, simplifies production flow, improves working environment of workers, and avoids occupational hazards of hydrargyrism.
Description
Technical field
The present invention relates to a kind of lighting field, especially a kind of fluorescent lamp.
Background technology
The efficient energy-saving technical advantage of fluorescent lamp, be fluorescent lamp since many decades, more and more become the reason of human main lighting source so far.In fact, fluorescent lamp has become global architectural lighting and has used main, the most general, also be to use the maximum important light source of quantity, the conventional fluorescent lamps principle of luminosity is the filament conductive heater, cathode emission goes out electronics, the ionization with the collision of (filling in the fluorescent tube) inert gas, mercury solution turns to mercury vapour, under electronic impact and two ends electric field action, the a large amount of ionization of mercury ion, negative ions motion forms gas discharge, i.e. arc discharge gives off energy simultaneously and produces ultraviolet ray, after fluorescent material on the glass tube inwall absorbs ultraviolet energy, be excited and emit visible light.So the fluorescent lamp full name is: low-pressure mercury (mercury) steam discharge lamp with luminescence.But illuminations such as common fluorescence have also brought the mercury pollution problem of environment, it is reported, at present, in China, a caliber is that 36mm extra heavy pipe T12 fluorescent lamp mercury content directly is 25-45mg, caliber is that the T5 fluorescent lamp mercury content in 16mm tubule footpath is 20mg, and the compact fluorescent lamp mercury content that caliber is 10mm is 10mg.Annual now about 1,000,000,000 of the fluorescent lamp of producing of China is 30mg by the average mercury content of every tubes, and mercurous total amount is about 30 tons in the annual fluorescent lamp of producing of China.And the mercury that is consumed in actual production process is far longer than this numeral.T12 straight tube fluorescent lamp with 40W is an example, by the automatic assembly line automatic mercury filling, needs to inject the mercury of 20-40mg, and adds processes expend, and actual consumption mercury amount is 60-100mg.It is calculated that the actual consumption mercury amount average out to 45.04-48.00mg of every fluorescent lamp production of China at present produces 1000000000 mercury amounts that fluorescent lamp consumed per year about the 47-60 ton.According to the prediction of the electric light source industry development of China, by 2015, the fluorescent lamp output of China will reach 2,000,000,000.If the mean consumption mercury amount when the average mercury content of product and production is still kept present level, so, by 2015, will be more than 90 tons up to about! After the fluorescent lamp fragmentation, contained mercury vapour enters in the ambient air immediately, and at this moment the airborne around instantaneous concentration of mercury can reach every cubic metre of 10-20mg, is higher than every cubic metre of 0.01mg of maximum acceptable concentration of national regulation far away.
In February, 2003, parliament of European Union and EU Council formally announce with the 2002/95/EC literary composition: the electrical and electronic product that requires to enter European Union from July 1st, 2006 all should meet European Union's poisonous and harmful substance illegal instruction (Restriction of Hazardous Substances is called for short RoHS).This instruction mainly is that the lead in the product, mercury, cadmium, Cr VI, Polybrominated biphenyl and Polybrominated biphenyl ether content are limited.
Along with the popularization of illumination, the increase of landscape light in city demand, for satisfying different visual art effects, increasing color fluorescence fluorescent tube is applied to and sets off in the Landscape Lighting, likes color according to different visions, satisfies different needs.The principle of luminosity of color fluorescence fluorescent tube is the same with the low mercury vapor pressure fluorescent tube principle of general lighting, unique difference with used fluorescent material, this fluorescent material is when being subjected to 253.7nm spectral line that the mercury atom transition launched and exciting, the ultraviolet light of 253.7nm can be changed into visible light, different colors be arranged according to the difference of fluorescent material.
Can current will the solution be on the basis of compliance with environmental protection requirements, can guarantee again the photochromic demand that meets Landscape Lighting that can send just to relate to two problems:
1. a kind of substitute materials of mercury can be launched certain spectrum when atomic transition, or continuous spectrum, or line spectrum.
2. a kind of fluorescent material can absorb the spectrum that the above-mentioned substance transition is sent, and changes into visible ruddiness.
Summary of the invention
At the problems referred to above, the invention solves and under no mercury condition, can make atom make fluorescent material send visible light before the moon, provide a kind of large red not have the fluorescent lamp of mercury.
The technical solution adopted in the present invention is: a kind of fluorescent lamp, it comprise glass tube, glass tube two ends lamp holder, stem stem, be sealed in electrode and neon in the glass tube, on described glass tube inwall, scribble fluorescent material;
The main component of described fluorescent material is:
Fluogermanic acid magnesium europium 3.5MgO0.5MgF
2GeO
2: Mn
Magnesium arsenate 6MgOAs
2O
5: Mn
4+
The percentage by weight of fluogermanic acid magnesium europium of the present invention is 30%-50%, and the percentage by weight of magnesium arsenate is 49%-69%.
The percentage by weight of fluogermanic acid magnesium europium of the present invention is preferably 40%, and the percentage by weight of magnesium arsenate is preferably 59%.
Adopt technical scheme of the present invention can obtain a kind of decorative fluorescent lamp that is used for of sending red visible light.
Technical solution of the present invention need not used the mercury raw material and avoid pollution to environment, has simplified production procedure simultaneously yet, has improved workman's operational environment, has avoided the occupational hazards of mercury poisoning.
