Chip in the light-adjusting module is mounted with the control light-emitting component carries out work according to different light intensity or flash of light software module.

At last, there is an annular groove at the rear portion of the undergauge section of described hollow stack shell, is with the annular ring of a breach on it, is spacing the cooperation with hollow sleeve internal face back segment.

Described transistor amplifier circuit is the single-stage transistor amplifier circuit.

Compared with prior art, advantage of the present utility model is: what the annulus of focus adjusting mechanism adopted is that coloured light-transmitting materials is made, torch sends light time scattering from the side, play warning function, be convenient to open-air personnel and observe, have light-adjusting module in the control loop, can send different multiple light, as illumination difference or flicker frequency difference,, widened range of application to satisfy the different demand of user.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of torch comprises hollow stack shell 7, and inside can supply ccontaining at least one batteries 8, is preferably two batteries, and inner front and back ends is respectively equipped with preceding internal thread, back external screw thread, and outer front end also is provided with preceding external screw thread; The front end of the rear end cap 9 of belt switch is provided with preceding internal thread, is screwed onto on the back external screw thread of hollow stack shell 7, and the inside is lined with sealing ring 10; The rear end that is provided with the lamp socket 5 of light-emitting component 11 has back external screw thread to be connected with the preceding internal thread of hollow stack shell 7, what light-emitting component 11 adopted is the LED light emitting diode, be fixed on the pad in the lamp socket 5 by a collar 12, the external screw thread of collar 12 is connected with the preceding internal thread of lamp socket 5; The leading portion of hollow stack shell 7 is a undergauge section, the rear end of the hollow sleeve of passing before and after the straight line 4 is placed in the undergauge section of hollow stack shell 7, there is an annular groove at the rear portion of the undergauge section of hollow stack shell 7, be with the annular ring 6 of a breach on the annular groove, with step surface on hollow sleeve 4 internal faces or back segment is spacing cooperates; Lens 3 are set against on the circle bad 2 on rank in, what this annulus 2 adopted is that coloured light-transmitting materials is made, as blue or red transparent plastic, annulus 2 two ends are respectively arranged with external screw thread and are connected with the internal thread of the retainer ring 1 of focus adjusting mechanism and the internal thread of hollow sleeve 4; What these lens 3 adopted is planoconvex spotlight, and is aspheric planoconvex spotlight, when making it carry out the zoom adjustment, can produce best expansion light or spotlight effect, and hollow sleeve 4, lens 3, annulus 2 and retainer ring 1 have been formed a focus adjusting mechanism like this; And battery 8, light-emitting component 11, lamp socket 5, hollow stack shell 7, switch have been formed an illumination control loop, have a light-adjusting module in the described illumination control loop, light-adjusting module is controlled by a chip IC, the base stage of triode Q1 connects the signal output part that a resistance R 1 inserts chip IC, the emitter stage of triode Q1 connects light-emitting component LED ground connection then, and the colelctor electrode of triode Q1 links to each other with the positive pole of power supply; The positive pole of power supply connects the positive pole of a diode D2 again, and the negative pole of diode D2 inserts a port of chip IC, and the negative pole of diode D2 connects the positive pole of an electrochemical capacitor C1 again, and the negative pole of electrochemical capacitor C1 joins with ground; The positive pole of diode D1 inserts the positive pole of power supply, and the negative pole of diode D1 inserts the detection signal input of chip IC, and the negative pole of diode D1 connects resistance R 2 back ground connection; Another pin ground connection of chip IC is formed a complete light-adjusting module; The outer peripheral face of the rear end cap 9 of switch, along the central shaft of the rear end cap 9 of switch to, at interval suitable apart from ground around being provided with most long recess, with usefulness as modification attractive in appearance.
