Description

Varifocal LED lamp
Technical field
The utility model relates to the illuminating lamp technical field, especially relates to a kind of varifocal LED lamp.
Background technology
At present, because of the LED light fixture has the advantage energy-conservation, that brightness is high, illumination, decoration etc. have been used to; Existing LED illuminating lamp can't focus on mostly, and light beam disperses, and utilization rate is not high; Even can focus on, also modes that adopt internal and external threads to cooperate when focusing more; Lamp holder is prone to revolve to take off from the lamp tube cause inconvenience, and screw thread damages easily, causes and can't focus.Therefore be necessary existing LED illuminating lamp is improved.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of varifocal LED lamp, and it has adjustable focus, and focus adjustment is simple, convenient, stable, the characteristics that lamp holder can not come off from the lamp tube during focusing.
To achieve these goals, the technical scheme that the utility model adopted is: varifocal LED lamp comprises lamp holder, is provided with lamp tube, the lamp socket of led light source; Lamp holder is fixed on the front end of lamp tube, and the lamp tube is fixed on the lamp socket, and the outer surface of lamp tube is provided with helical groove; Be provided with external magnet in the helical groove, external magnet protrudes out to outside the helical groove, and the outside of lamp tube is with focusing drum; The inner surface of focusing drum is provided with the axial notch that matches with external magnet, and the inside of lamp tube is with lens post, and lens post is positioned at the place ahead of led light source; The internal fixation of lens post has convex lens, is inlaid with the internal magnet that attracts mutually with external magnet on the wall of lens post.
Said axial notch and helical groove respectively are three that evenly are provided with around circumference, and external magnet and internal magnet respectively are three.
Said external magnet is cylindrical.
The outer surface of said lamp tube is provided with accepting groove, is provided with turn in the accepting groove, and turn matches with the locating slot that focusing drum inside is offered.
Said lamp holder is through the lamp tube that is threaded.
After adopting said structure; The utility model is compared the advantage that is had with prior art: 1, the convex lens in the lens post can focus on the light beam that led light source sends; And can change the focal position, thereby produce the effect of different illuminations through the distance of regulating between convex lens and the led light source.2, rely on the cooperation of axial notch and helical groove, external magnet moved at lamp tube external spiral, and drive internal magnet, lens post is slided before and after rotating; Thereby change the distance between convex lens and the led light source, with respect to the existing mode of taking threaded adjusting, convex lens move steadily, the position is accurate; The situation that lamp holder rocks can not appear; Making the focusing operation highly stable, accurate, and whole operation only need be rotated focusing drum, simple, the convenience of focus adjustment.3, focusing process is without the turn lamp holder, and lamp holder can not come off from the lamp tube when therefore focusing.4, turn is located between focusing drum and the lamp tube, makes fasteningly relatively between the two, and focusing drum can not rotate because of careless touching.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the overall structure sketch map (broken section) of the utility model embodiment;
Fig. 2 is the three-dimensional decomposition texture sketch map of the utility model embodiment;
Fig. 3 is the horizontal sectional structure sketch map of lens post;
Fig. 4 is the horizontal sectional structure sketch map of focusing drum;
Fig. 5 is vertical sectional structure sketch map of focusing drum;
Fig. 6 is the structural representation of turn.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see that Fig. 1 is to shown in Figure 5: varifocal LED lamp mainly contains lamp holder 1, lamp tube 4, focusing drum 3, lens post 2, lamp socket 6 compositions.
Lamp holder 1 is provided with transparent glass sheet 11 through the front end of the lamp tube 4 that is threaded in the lamp holder 1, like this can printing opacity, can prevent that also dust from getting into lamp tube 4.
Lamp tube 4 is connected on the lamp socket 6, and the outer surface of lamp tube 4 is provided with helical groove 41, is provided with external magnet 42 in the helical groove 41, and external magnet 42 protrudes out to outside the helical groove 41, and lamp tube 4 inner bottoms are provided with led light source 43.
Focusing drum 3 is enclosed within the outside of lamp tube 4, and lamp tube rotation relatively, and the inner surface of focusing drum 3 is provided with the axial notch 31 that matches with external magnet 42, holds external magnet 42 and protrudes out to the part outside the helical groove 41.Like this, rotation focusing drum 3, axial notch 31 drives external magnet 42 and in helical groove 41, moves.
Lens post 2 is positioned at the inside of lamp tube 4, the place ahead of led light source 43, and can in the lamp tube, move, rotate, and the internal fixation of lens post 2 has convex lens 21, is inlaid with the internal magnet 22 that attracts mutually with external magnet 42 on the wall of lens post 2.When external magnet 42 moves in helical groove 41, drive internal magnet 22, lens post 2 rotations, move, thereby change the distance of convex lens 21 and led light source 43, reach the purpose of focusing.
