The beneficial effects of the utility model are: because the utility model comprises stop screw, lens carrier, adjustable ring, described lamp body comprises the headlight body, the back light body, the head of described back light body, afterbody respectively with the afterbody of described headlight body, described back seat is fixedly connected, described lens are fixed on the described lens carrier, described adjustable ring and described headlight are connected in axial restraint and circumferentially rotating, the sidewall of described lens carrier is provided with guide groove, external screw thread, described adjustable ring is provided with internal thread, described external screw thread matches with described internal thread and is connected, described stop screw is fixed on the described back seat and stretches out in the sidewall of described back seat, described stop screw is connected with described guide groove is suitable, the utility model cooperates by described stop screw and described guide groove, described lens carrier and described lens can only can not circumferentially moved moving axially, described adjustable ring is when described headlight body rotates, by cooperating of described external screw thread and described internal thread, drive described lens carrier and described lens move up and down vertically, thereby can regulate the distance between described lens and the LED, change the light focusing point of described LED through described lens, not only can control the angle of bright dipping, and make and also can regulate at the spot size that shines preset distance and change size, in addition when regulating spot size, its illumination also changes thereupon, hot spot is more little, illumination is high more, hot spot is big more, illumination is low more, be that distance between the utility model lens and the LED can be regulated as required, and it is easy to adjust, the utility model spot size make light fixture when different occasions are used, can adjust hot spot and illumination size as required, so can be adjusted;

Because back seat described in the utility model is provided with through wires hole, power line inserts on the LED of inner described belt substrate, so the utility model wiring is simple and convenient by described through wires hole;

Because the afterbody of back seat described in the utility model is provided with handle, it is easy for installation that described handle makes that light fixture picks and places, and assembly and disassembly is convenient, the needs of outward appearance appearance have not only been satisfied, also can be used as connector, the utility model is used as base unit, can realize the design of series of products by assembling combination, so the utility model picks and places, easy accessibility, can satisfy various design needs;

Because the LED of belt substrate described in the utility model has aluminium base, described back seat, described headlight body, described back light body all adopt the aluminium manufacturing, described back light is on one's body along being circumferentially with some radiating fins, the heat that LED produces when especially great power LED is luminous is transmitted to described back seat, described back light body and described headlight body and is dispersed in the air rapidly by its aluminium base, so the utility model good heat dissipation effect, long service life.
