Description

Portable inspection lamp

The utility model relates to a kind of lamp, is used for the lamp that site inspection is used in the particularly public security criminal case.

It is to scout the important step of solving a case that criminal case crime scene is reconnoitred, and the trace evidence that extracts in the site inspection will be directly connected to the detection of case.Therefore trace inspection technical staff must be careful when reconnoitring the scene, comprehensively, seek, find, study, extract all on-the-spot vestiges fastidiously.On-the-spot vestige major part is that dust and sweat are formed, the few face of amount is little generally speaking, often stay in the object surface and find because of the little and difficult observation of contrast, trace inspection technical staff adopts light-illuminating as ancillary method usually in reconnoitring at the scene, strengthen vestige and the contrast of holding trace object surface with the brightness of adjusting light and the method for direction, improve observing effect, and vestige is found; When reconnoitring the scene, can the light application time of site inspection lamp, illumination brightness, illumination function directly determine site inspection carry out smoothly.In addition, in the ordinary course of things, trace inspection technical staff has only the walking of 1-2 name to enter the scene when reconnoitring the scene, and must carry a cover complete reconnoitre equipment, this just requires the equipment body of trying one's best gently and again to possess multi-functional in a small amount.Up to the present domestic, reconnoitring the on-the-spot main lamp of reconnoitring that uses has: flashlight, high light torch, on-the-spot illuminating lamp, multi-functional onsite are reconnoitred lamp." torch " letter is the most original, but still reconnoitre on-the-spot main light fixture so far, its major advantage is light, owing to use dry cell as the energy, not only brightness is not enough, also Chang Yinwei power shortage and can not keep original brightness that the preliminry basic research effect is reduced is omitted some unconspicuous vestiges; " high light torch ", advantage is that brightness is strong, under its irradiation vestige is come into plain view, but its use is rechargeable battery, energy is too little, lighting hours can only remain on about 1 hour, the Chang Yinwei electric energy uses up and site inspection is interrupted, and the employed rechargeable battery deal of this torch is heavier, should not be with when reconnoitring the scene more, can only use general torch to continue to reconnoitre after electric energy uses up, the searching that has directly influenced on-the-spot vestige is found; " on-the-spot illuminating lamp " adopts batteries as power supply, and service time is longer, but lamp body, battery volume are all bigger, must put into lamp box or hand held, carry quite inconvenience; Moreover, more than three kinds reconnoitre lamp and all can only adopt general illumination to penetrate, rely on the adjusting of its brightness and light-source angle to control the readability of vestige fully.Over the past two years, " multi-functional onsite is reconnoitred lamp " enters the scene, the characteristics of this lamp are to adopt each coloured light such as polarised light, blue light, ruddiness that vestige is shone, strengthen vestige and the contrast of holding the trace object with the method for regulating colour band, but this lamp shortcoming is that volume is big, deal weight, complex structure, price are high and perishable, is difficult to the large tracts of land penetration and promotion.

The purpose of this utility model is exactly in order to address the above problem, and a kind of luminous intensity height, irradiation time length, light practicality, durable in use, the cheap portable lamp of reconnoitring are provided.

Technical solution of the present utility model:

A kind of portable lamp of reconnoitring, it includes lamp holder (1) and handle (2), be provided with high light fontanel tungsten bulb (3) and glass face (4) thereof in the lamp holder (1), on-off switch (5) is located on the handle (2), it is characterized in that high light fontanel tungsten bulb (3) is drawn from handle (2) by lamp line (6) connects electronic transformer (7), electronic transformer (7) is provided with attaching plug (8), so that directly be plugged on the AC power, the front port of lamp holder (1) is adapter ring screw thread mouth (9).

The utility model adopts alternating current as power supply, and is unrestricted in the service time of the site inspection lamp that AC power is arranged, and the assurance of light source is provided for comprehensive careful scene of reconnoitring.Also having small-sized storage battery in addition uses in the scene of AC-less power.The utility model is the high light torch bulb, and the prolongation and the time can have no limits of its brightness such as high light torch is under the floodlighting site inspection all the time and carries out.Screw socket adapter ring of the present utility model can insert polarised light camera lens or the various colour filter camera lens in the camera installation where necessary, strengthen vestige and the contrast of holding the trace object with the method for regulating colour band, strengthen the readability of vestige, improve the discovery rate and the utilization rate of vestige.The utility model lamp body is little, and is in light weight, be convenient to carry, and light practicality, its price is also very cheap, is convenient to apply in vast basic unit.

Fig. 1 is a structural representation of the present utility model.

As Fig. 1, when the utility model uses, if there is AC power at the scene, attaching plug (8) is inserted power supply, make electronic transformer (7) work, it can regulate output voltage in the 3.5-8.5V scope, make fontanel tungsten bulb (3) light work, its brightness is big, and service time is unrestricted.The internal diameter of the adapter ring screw thread mouth (9) of the utility model lamp holder front port is 4.9cm or 5.2cm, polarised light camera lens in the camera installation or various colour filter camera lens can be inserted where necessary, strengthens vestige and the contrast of holding the trace object with the method for regulating colour band.Result of use is very desirable.

Claims (2)

1, a kind of portable lamp of reconnoitring, it includes lamp holder (1) and handle (2), be provided with high light fontanel tungsten bulb (3) and glass face (4) thereof in the lamp holder (1), on-off switch (5) is located on the handle (2), it is characterized in that high light fontanel tungsten bulb (3) is drawn from handle (2) by lamp line (6) connects electronic transformer (7), electronic transformer (7) is provided with attaching plug (8), so that directly be plugged on the AC power, the front port of lamp holder (1) is adapter ring screw thread mouth (9).
