Specific implementation mode
To keep the technical solution of the utility model and advantage clearer, the utility model is implemented below in conjunction with attached drawing
Mode is described in further detail.
Light compensating lamp provided by the utility model includes turnbarrel, lens, fixes sleeve and driving device.Fixing sleeve jacket casing
It is located in turnbarrel, lens are arranged in one end of fixes sleeve, and lens include Fresnel Lenses；Lamp body is arranged in fixes sleeve
Interior, lamp body is provided with visible light source or/and infrared light light source, and turnbarrel is connected with driving device and lamp body respectively, rotation
Sleeve is configured as driving lamp body under the drive of the drive, and lamp body is made closer or far from lens to be moved in fixes sleeve
It is dynamic.
The turnbarrel of the light compensating lamp of the utility model drives lamp body under the drive of the drive, keeps lamp body close or remote
It from lens is moved in sleeve, therefore the distance variable of lamp body and lens closely becomes remote, to change light-emitting angle, light filling region
Range size change therewith, since distance is consecutive variations, the light-emitting angle of light filling is also continuously adjusted, not office
It is limited to certain several special angle.Light compensating lamp provided by the utility model is shown with specific embodiment below.
One embodiment of the utility model provides a kind of light compensating lamp, and Fig. 1 and 2 is the cross-sectional view of the light compensating lamp,
Fig. 3 is the positive structure diagram of the light compensating lamp, and Fig. 4 is the dimensional structure diagram of the light compensating lamp, and Fig. 5 is bowing for the light compensating lamp
Depending on structural schematic diagram.
As shown in Figs. 1-5, light compensating lamp includes turnbarrel 1, lens 2, lamp body 3, fixes sleeve 4 and driving device 5.
Fixes sleeve 4 is set in turnbarrel 1, and two sleeves generally are cylinder-like structure, i.e. circular in cross-section
Or it is roughly circular.Turnbarrel 4 is located at 1 outside of fixes sleeve, can rotate, and fixes sleeve 1 is when turnbarrel 4 rotates one
As keep being in a fixed position.
Lens 2 are arranged in one end of fixes sleeve 4.Lens 2 include Fresnel Lenses.Lens 2 utilize refraction principle, make lamp
The light that body 3 is sent out after lens 2 within the scope of certain angle by being emitted.
Lamp body 3 is arranged in fixes sleeve 4.Lamp body 3 is provided with visible light source or infrared light light source, can also be simultaneously
Both light sources are set, are emitted beam for light filling.
Turnbarrel 1 is connected with driving device 5 and lamp body 3 respectively.Turnbarrel 1 plays the role of transmission, is configured as
Lamp body 3 is driven under the driving of driving device 5, so that lamp body 3 is moved up in the axial direction in fixes sleeve 4 dynamic, as driving fills
The variation of 5 driving direction is set, 1 direction of rotation of turnbarrel also can be different, are based on the direction of rotation, and lamp body 3 can be close to thoroughly
Mirror 2 or far from lens 2, for example, counterclockwise rotation when moved far from lens 2 when moving and rotating clockwise to lens 2, Huo Zheshun
It is moved far from lens 2 when moving to lens 2 when hour hands rotate and rotating counterclockwise.
Fig. 1 shows light compensating lamp section of the lamp body 3 near lens 2 when, at this time since the position of lamp body 3 is near lens
2, therefore beam projecting angle is maximum, light filling range is also maximum, is suitable for the nearest focal length of the lens assembly mating with light compensating lamp
It is corresponding.
Light compensating lamp section when Fig. 2 shows lamp bodies 3 farthest away from lens 2, at this time since the position of lamp body 3 is farthest away from lens
2, therefore beam projecting angle is minimum, light filling range is also minimum, is suitable for the farthest focal length of the lens assembly mating with light compensating lamp
It is corresponding.
Obviously, in order to adjust the light-emitting angle of light compensating lamp, as long as by the setting of lamp body 3 from 2 suitable position of lens,
So as to continuously adjust the light-emitting angle of light compensating lamp, adopted with real focal length corresponding to the lens assembly mating with light compensating lamp
With most suitable light filling angle, it is no longer limited to several fixed light filling angles.
