Abstract
The utility model belongs to the technical field of electric light sources is a cold cathode ultraviolet light source which is formed by a quartz tube that can penetrate the ultraviolet rays of 254nm, after the quartz tube is bent in omega type, sealed in parallel with the electrode, and filled with the mercury and the mixture gas of neon and argon. The ultra miniature and portable cold cathode ultraviolet source has the characteristics of firm structure, breaking resistance, compactness, reasonableness, excellent uniformity of volume, small volume and long life time.
Description
Affiliated technical field
The utility model belongs to the electric light source technology field, and relating to a kind of the employing can be microminiature, the portable cold cathode ultraviolet source that material is made by the ultraviolet quartz ampoule of 254nm.
Background technology
At present, common ultraviolet source mostly adopts the hot cathode structure, and power is generally more than 8W, though ultraviolet radiant illumination is than higher, but volume is big, is difficult for carrying, and has the low power ultra-violet lamp of some cold cathodes to make for manual, size is inconsistent, and it is attractive in appearance that outward appearance is owed, and the bending place is easily broken.
Summary of the invention
For the sterilizing in adapting among a small circle, and can be convenient for carrying, design a kind of high conformity, but outward appearance exquisiteness, compactness, the mechanization of non-frangibility are produced ultra-fine cold cathode low-voltage mercury ultraviolet light source.
The technical scheme that its technical problem that solves the utility model adopts is: ultra-fine quartz ampoule is curved parallel two-tube single-ended, and the bending place is Ω (Omega) type, has effectively overcome two frangibility that parallel bending place exists, the shortcoming of being unable to undergo vibrations.The two-tube single-ended mechanical sealing by fusing that adopted, compact, attractive in appearance and high conformity, easy to make, good looking appearance.
The beneficial effects of the utility model are to produce high conformity, anti-vibration, long-life, miniature, portable ultraviolet sterilization light source in batches easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is an end view of the present utility model.
1. exhaust outlets among Fig. 1 Fig. 2,2. Ω type bend pipe, 3. discharge tube, 4. sparking electrode, 5. press seal place in plane is connected molybdenum sheet with electrode, and 6. quartz discharge tube and molybdenum sheet soak into sealing-in, 7. outer conductor.
Embodiment
The shape that ultra-fine ozone free quartz ampoule is curved Ω type bend pipe is seen Fig. 1, connect exhaust outlet (1) in (2) upper end, electrode (4), outer conductor (7) are welded on impulse spot welder with molybdenum sheet (5), will be firmly soldered up (4) (5) (7) pack into the port of (3), with coal oxygen flame (6) are located the sealing by fusing crimping, after (1) is located atmosphere drained, charge into liquid mercury and drip and the argon neon mixture body.
Claims (2)
1. ultra-fine cold cathode low-pressure mercury ultraviolet light source, in quartz ampoule, charge into inert gas, liquid mercury, the ultraviolet ray of under two end electrodes and mercury vapour effect, emitting 254nm, it is characterized in that two ultra-fine quartz ampoules are closely parallel, the top is the Ω type, exhaust outlet is positioned at Ω type top, and electrode is a ∩ type molybdenum rod.
2. ultraviolet light source according to claim 1 is characterized in that the sealing-in position is that two pipes are parallel, a sealing-in.
