Abstract
The utility model belongs to the fluorescent lamp tube, especially relates to an environment-friendly type medicine inspection lamp, comprising a tube body and lamp feet arranged at the both sides of the tube body. Electrodes are arranged in the lamp feet, and are connected with filaments via core columns fixed in the interior of the tube body, and the inside wall of the tube body is coated a phosphor layer. The environment-friendly type medicine inspection lamp is characterized in that, the filaments and electrodes are fixedly connected with cyclic titanium amalgam. The beneficial effects are that, the electric field distribution in the lamp is changed by employing the titanium amalgam to substitute liquid mercury, being conducive for the cathode to develop toward miniaturization; the titanium amalgam can not decompose below 500 DEG C, so that there are both not existed mercury vapor pollutions at room temperature and in the lamp production and exhaust processes, reducing the pollution of the liquid mercury to environment substantially; there is not existed fluctuation effects of the mercury vapor pressure in the exhaust production process, the consistency of the inert gases filled in the lamp is very high, improving the consistency and stability of the product performance index; and the radiation intensity of the lamp tube can reach up to 6000 lx, improving the service life of the lamp tube effectively.
Description
Technical field
The utility model belongs to fluorescent tube, relates in particular to a kind of environment-friendly type medicine inspection lamp.
Background technology
The clarity detector is mainly used in the detection of liquid drug with the medicine inspection lamp, pharmacy corporation requires very strict to the cleanliness factor of its production environment, traditional medicine inspection lamp mainly adopts liquid mercury to inject fluorescent tube, mercury atom is stimulated in fluorescent tube and produces ultraviolet ray, play the sterilizing effect by this ultraviolet ray excited light-emitting phosphor or through tube wall, at present domestic enterprise to produce a caliber be that 36 millimeters extra heavy pipe footpath medicine inspection lamp mercury content is between 25-45 milligrams, caliber be 26 millimeters tubule footpath medicine inspection lamp mercury content then about in the of 20 milligrams, and caliber to be 10 millimeters compact medicine inspection lamp mercury content also have an appointment 10 milligrams.If fluorescent tube breaks or discards and will cause great pollution to medicine aborning.In addition, the injection rate of fluorescent tube manufacturing enterprise liquid mercury is not easy control, and the injection rate that tends to occur mercury is too much or very few, thereby to such an extent as to causes the irradiation intensity of medicine inspection lamp unstable useful life of reducing fluorescent tube.Moreover the medicine inspection lamp is in the process of making, and the volatilization meeting of mercury damages the direct labor, the mercury poisoning phenomenon occurs.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of environment-friendly type medicine inspection lamp that adopts solid-state mercury is provided, and can reduce the harm of mercury to human and environment, improves the useful life and the stability of medicine inspection lamp.
The utility model for achieving the above object, by the following technical solutions: a kind of environment-friendly type medicine inspection lamp, comprise body and the lamp base of being located at the body two ends respectively, described lamp base inside is provided with electrode, described electrode is connected with filament by the stem stem that is fixed on body inside, described inboard wall of tube body scribbles phosphor powder layer, it is characterized in that: be connected with ring-type titanium amalgam on described filament and the electrode.
Be provided with the titanium white bisque between described inboard wall of tube body and phosphor powder layer.
Beneficial effect: 1, adopt the solid-state mercury of ring-type titanium amalgam to substitute liquid mercury and changed Electric Field Distribution in the lamp, help negative electrode and develop to miniaturization; Because the titanium amalgam can not decompose below 500 ℃, does not discharge mercury atom, therefore at room temperature, and in system lamp bank gas process, all do not have mercury vapour and pollute, greatly reduce the pollution of liquid mercury to environment; 2, the influence of fluctuations of no mercury vapor pressure in the exhaust production process, high to the pressure consistency that charges into the inert gas in the lamp, consistency and the stability of product performance index (life-span, light logical etc.) have been improved, the fluorescent tube irradiation intensity can effectively improve the useful life of fluorescent tube up to 60000 luxs.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A direction cutaway view.
Among the figure: 1, body; 2, lamp base; 2-1, electrode; 3, stem stem; 4, filament; 5, phosphor powder layer; 6, ring-type titanium amalgam; 7, titanium white bisque.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of environment-friendly type medicine inspection lamp, the lamp base 2 that comprises body 1 and be located at the body two ends respectively, described lamp base inside is provided with electrode 2-1, described electrode is connected with filament 4 by the stem stem 3 that is fixed on body inside, described inboard wall of tube body scribbles phosphor powder layer 5, it is characterized in that: be connected with ring-type titanium amalgam 6 on described filament and the electrode.The titanium amalgam be titanium elements and mercury element under 800 ℃ high temperature,, then this alloy pulverize is compressed on the nickel strap one deck of the another side of nickel strap compacting simultaneously getter material, i.e. ZrAL16 alloy with the intermetallic compound Ti3Hg that forms in the airtight container.The titanium amalgam is after can not decomposing below 500 ℃, making fluorescent tube, and nickel strap is heated to by the stem stem high-frequency current Ti3Hg is decomposed, and discharges contained mercury atom.Therefore, be can not pollute to environment in manufacture process or in damage in the future, solid-state in addition titanium amalgam material can be strict control mercurous content, with the 39W fluorescent tube is example, the content of mercury can be strict controlled in below the little 15mg, in order effectively to improve the irradiation intensity of fluorescent tube, between inboard wall of tube body and phosphor powder layer, scribble one deck titanium white bisque 7.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
