Abstract

The utility model belongs to a daily small electric appliance; the technical scheme of the utility model is that: a portable daylight lamp flashlight comprises a lamp tube 1, a lampshade 2, a circuit board 3, a switch 4 and a power supply part, and is characterized in that the rear end of the lampshade 2 is connected with the front end of a sheath 7, an oscillation boosting circuit board 3 is arranged in the sheath 7, the lamp tube 1 is arranged in the lampshade 2, and the rear end of the lamp tube 1 is inserted into the sheath 7 and connected with four pins of a transformer of the circuit board 3; the circuit board 3 can be directly connected with the battery 5 assembled outside the sheath 7 (integrated type), and can also be connected with an external battery through a fish clip 6 led out from the circuit board 3 (split type); the utility model has small volume, strong visual brightness, good light color, no eye injury, fast start and power saving; the product has long service life, low cost and wide application range, and is not only suitable for families, but also can be used in various environments such as the field, rain, underwater, underground and the like.

Description

Portable fluorescent lamp torch

Affiliated technical field

The utility model belongs to daily small electric apparatus.

Background technology

The flashlight that uses in our daily life all is a miniature incandescent lamp, and this torch is easy to carry, but has brightness little, photochromic poor, electricity wasting, shortcoming such as lighting area is little, and photochromic good, the brightness height, family's Emergency daylight lamp that lighting area is big extremely is not easy to again carry.

Summary of the invention

The purpose of this utility model is all avoided the two shortcoming exactly, and its advantage is integrated, and invents the big and portable torch of a kind of both brightness.

The technical solution of the utility model is: portable fluorescent lamp torch, comprise fluorescent tube 1, lampshade 2, circuit board 3, switch 4 and power unit, the rear end that it is characterized in that lampshade 2 is connected with the front end of sheath 7, oscillation step-up circuit plate 3 is placed in sheath 7 pipes, fluorescent tube 1 is contained in the lampshade 2, insert in sheath 7 pipes rear end of fluorescent tube 1, links to each other with transformer four pin of circuit board 3.Circuit board 3 can directly be connected (combination type) by the battery 5 outer with being assembled in sheath 7, also can press from both sides 6 link to each other with external connection battery (split type) by the fish of being drawn by circuit board 3.Said circuit part has charging circuit and operating circuit separately, and the booster circuit in the operating circuit has used the few single tube transformer oscillating circuit of element.

Portable fluorescent lamp torch can be made into two kinds of forms, a kind of is split type, a kind of is combination type, and its difference is the position of battery, the split type external connection battery of wanting, the battery that can connect different sizes according to different demands, such as when the emergency light, can use the battery of big capacity (more than the 4Ah), and during as portable torch, the battery of available 1.2Ah, its operating voltage all are 6V.Employing 5 * 1.2V nickel-hydrogen chargeable cell power supply of combination type, this lamp is more convenient for carrying, but battery capacity is in a single day definite, can't at will change.

The utility model portable fluorescent lamp torch operation principle and family's emergency light are similar, but because the utility model circuit has only several elements, therefore the manufactured goods volume is very little, though volume is similar with 3 * 1.5V1 battery flashlight of family expenses, its visual brightness is but strong ten to twenties times than common flashlight, and it is photochromic good, do not hinder eye, start soon, power saving, this novel product life-span is long, cost is low, applied widely, be not only applicable to family, also can be in the open air, in the rain, under water, multiple environment such as down-hole uses down.

Description of drawings:

Fig. 1 is the utility model embodiment 1 (combination type) circuit general assembly drawing; Fig. 2 is the utility model embodiment 2 (split type) schematic appearance.Among the figure, 1. fluorescent tube, 2. lampshade, 3. circuit board, 4. switch, 5. battery, 6. fish folder, 7. sheath.

Embodiment 1: the combination type torch, with an internal diameter 20-30mm, plastics about wall thickness 2mm or metal tube are made sheath 7, fuselage oscillation step-up circuit plate 3 is placed directly in sheath 7 pipes, the rear end of lampshade 2 is connected with the front end of sheath 7, fluorescent tube 1 is contained in lampshade 2 times, insert in sheath 7 pipes rear end of fluorescent tube 1, link to each other with transformer four pin of circuit board 3, switch 4 is located at jacket surface, battery pack 5 is directly around being assembled in sheath 7 outsides, is connected with jack (charging with) on being located at sheath 7 by a diode.

Embodiment 2: split type torch, and part such as fluorescent tube 1, lampshade 2 and circuit board 3, sheath 7 is identical with example 1, and circuit board 3 usefulness leads are drawn two fish folders 6, are used to connect external power supply 5 (battery pack).
