Abstract
The utility model discloses a fluorescent lamp with long service life. The fluorescent lamp with long service life comprises a glass tube whose inner wall is provided with fluorescent powder; a glass core column and a lamp filament are respectively arranged inside two ends of the glass tube in a sealing mode; and two electrodes connected with the lamp filament are arranged and supported on each glass core column. The fluorescent lamp with long service life is characterized in that an arc-shaped metal cover is respectively connected outside the two electrodes in the glass tube in a short-circuited mode. As an arc-shaped metal cover is respectively sleeved outside the lamp filament and the electrode, in comparison with the prior art, the arc-shaped metal cover on one hand can shield high temperature and electric sparks instantly generated between the electrodes when the lamp tube is started, and on the other hand, a function of quickly cooling the electrode and the filament can be achieved, possibility that the filament is burnout can be reduced, and the service life of the fluorescent lamp tube is greatly prolonged.
Description
Technical field
The utility model relates to a kind of ligthing paraphernalia, specifically a kind of durable fluorescent lamp.
Background technology
At present, known incandescent lamp will progressively withdraw from from 2012 illumination market, go out and generation be energy-conservation fluorescent lamp and LED lamp, although but the fluorescent lamp economize on electricity obviously, but because of its life-span limited, so be summarized as the energy-conservation product that does not save money, the short-lived reason of fluorescent lamp be because fluorescent tube moment produces between electrode and the electrode when starting high pressure, high temperature and electric spark with filament blow.And the LED lamp is high because of cost, price is high, can't be accepted by the public.Chinese patent 92212076.5 Multi-function longs.Be to have set up arcuation annular electro polar circle at two filament electrode, expanded the effective cross-section of filament electrode, improved the situation of filament electrode absorption and electron emission, make the useful life of fluorescent tube by original 3000 hours, extend to about 6000 hours.Although this patent ring ear is welded on the electrode, but arcuation annular electro polar circle is to be connected on the glass stem of filament electrode, not to be enclosed within outside filament and the electrode, although so have thermolysis, the high temperature that moment produces between electrode and the electrode when not shielding the fluorescent tube startup and the effect of electric spark.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple structure, reasonable, the fluorescent tube of long service life.
The technical scheme that its above-mentioned technical problem that solves the utility model adopts is: a kind of durable fluorescent lamp, it comprises that an inwall is with the glass tube of fluorescent material, seal respectively in the two ends of glass tube glass stem and filament are installed, install on the glass stem and be supported with two electrodes that are connected with filament, it is characterized in that: outside each short circuit of two electrodes in the described glass tube connects a curved metal cover.
The utility model since filament and electrode outside each cover one curved metal cover is arranged, against existing technologies, high temperature and the electric spark of moment generation between electrode and the electrode when curved metal cover can shield on the one hand fluorescent tube and starts; Play on the other hand rapid effect to electrode and filament cooling, reduced the probability that filament is blown, greatly prolonged the useful life of fluorescent tube.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. glass tube, 2. electrode, 3. filament, 4. curved metal cover, 5. glass stem.
Embodiment
