Abstract
The invention discloses a long-life energy-saving fluorescent lamp. The long-life energy-saving fluorescent lamp comprises a glass tube, a core column, filaments and lamp holders. The glass tube is filled up with mercury steam and inert gases, metal covers are arranged above the filaments, and through holes are arranged in the middle of the metal covers. The service life of the long-life energy-saving fluorescent lamp can be prolonged to more than 20 thousand hours.
Description
Technical field
The invention belongs to electric light source technology field, particularly relate to a kind of long-life energy-saving fluorescent lamp.
Background technology
At present, conventional fluorescent lamps society use amount is very big, and luminous element is large photochromic soft, easy to use, but the life-span is shorter, and general many at 10000 hours, the main cause of inefficacy is, cathode emission electronic powder exhausts and dies of old age; And, this conventional fluorescent lamps before failure one-phase due to negative electrode volatile substance get more and more, phosphor powder layer surface formed pollutant, have a strong impact on light output, light decay is large especially.For extending the useful life of fluorescent lamp, research manufacturing sector drops into a large amount of manpower and materials, has carried out unremitting effort.
Summary of the invention
The present invention is the deficiency overcoming the existence of above-mentioned prior art, and provide a kind of long-life energy-saving fluorescent lamp, its useful life extends to more than 20,000 hours.
The technical scheme that technical solution problem of the present invention is taked is, a kind of long-life energy-saving fluorescent lamp, comprises glass-tube, stem stem, filament and lamp holder, mercury vapor and inert gas is filled with in glass-tube, it is characterized in that, above described filament, be provided with metal cap, in the middle of described metal cap, be provided with through hole.
Preferred as one, the side of described metal cap is connected with filament foot nickel wire and fixes.
Preferred as one, in the middle of described metal cap, the diameter of set through hole is 2.5-3.5mm.
Preferred as one, described metal cap take nickel as material.
The present invention is when keeping former fluorescent lamp structure constant, above two termination electrodes and filament, install metal cap additional, and be provided with the through hole that diameter is 2.5-3.5mm in the middle of it, side is connected with the filament foot nickel wire of the other end.When lamp is energized, electric energy is generated heat by filament, Heating Electron powder, and when reaching 1100-1300 DEG C, electronic powder starts electron emission, and the other end receives electronics.Because metal cap nickel wire is connected to filament foot, negative electrode is formed electricity backflow, pass through metal cap interstitial hole to a part for the electronic current of surface launching, received by negative electrode, a part is received by metal cap, thus alleviates the load of negative electrode, and electronic powder consumption reduces.Add after loading onto basin type metal cap, change conventional fluorescent lamps and light in use procedure the situation having much too much electronics always doing reactive power consumption, electronics is launched by medial small hole limitation and limitation receives, when guaranteeing that filament work is good, greatly reduce the emission measure of electronics, the consumption of filament electronic powder painting reduces, the foreign gas that ignition procedures is overflowed also greatly reduces, thus extend electronic powder elapsed time, and phosphor surface pollution also greatly reduces, light decay is just less, thus reaches the life effect of fluorescent tube.
The present invention by arranging metal cap, and forms electricity backflow between metal cap and filament foot, and effective control cathode electronic powder is launched in right amount, extends electronic powder elapsed time, thus makes extend to more than 20,000 hours the useful life of fluorescent tube.
