Movable plug is provided with the bayonet socket that matches with the handle convex platform.

Heat sink is provided with a plurality of louvres.

Cathode fluorescent tube is the cold cathode spiral fluorescent tube.

Lampshade is the glass marble bubble-cap.

Handle is a detachable handle, matches with the long connecting line and the short connecting line of movable plug with light-operated switch.

The cold cathode mini light night that the utility model provides, beneficial effect is as follows:

1, owing to replace traditional thermal cathode fluorescent tube as light source with cathode fluorescent tube, the life-span can reach more than 50,000 hours, and the life-span is long, colour rendering good, and colour rendering index can reach 85～95Ra; Adopt high-quality three primary colors fluorescent powder, with under the constant power, light efficiency height, energy savings; The glass of fluorescent tube adopts crown glass, has the ultraviolet function of interception, can effectively stop ultraviolet light in the light to the human injury, has overcome the shortcoming of traditional thermal cathode fluorescent tube as light source.

2, cathode fluorescent tube fluorescent material coating evenly makes 100% UV light be converted to anti-dazzle, has solved the difficult coating of conventional fluorescent powder evenly, the problem that UV light leaks.

3, adopt solid mercury meter in the cathode fluorescent tube, mercury content can accurately be controlled, and is that 1.5～3.0mg/ props up, and meets international standard, has protected environment.

4, traditional ballast driven mode is changed into inverter and drive, driving frequency rises to 50～60KHz by 50HZ, has the advantage of no stroboscopic, flicker free under this high frequency, can prevent visual fatigue; And light source can be because of frequent switch damage, and the switch number of times is more than 5,000 ten thousand times, long service life; And light decay is little, and long-time use does not influence its illumination.

5, have the cold-starting function, in the time of 0 ℃ brightness unaffected ,-30 ℃ can normally start.

6, adopt optoelectronic switch control, evening or light are crossed when dark mini light night and can be opened automatically, have human oriented design.

7, the design of movable plug makes handle and plug flexibly connect, and can take off when not using, and has saved parking space, and selecting for use of cold cathode spiral fluorescent tube makes the lamp body structure compactness, and volume is little, installs easy to carry.

8, the bayonet socket on the movable plug matches with the handle convex platform, and movable plug not may be stuck on the handle when not using, in order to avoid lose.

9, thermal insulation board is provided with a plurality of louvres, has reduced the influence of heat to inverter, has prolonged the life-span of inverter.

10, handle can be removed, and the connecting line of light-operated switch and movable plug has long connecting line and two kinds of short connecting lines, when night, operating illumination needed, uses long connecting line, handle can be removed, and the utility model is used as the mobile working lamp, has versatility.
