To reduce the space occupancy rate of light filling cost and light compensating lamp.An embodiment of the present invention provides a kind of variable-angle light fillings
Lamp and video camera.To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one by the following examples
Step is described in detail.
With reference to figure 1, one embodiment of the invention provides a kind of variable-angle light compensating lamp, is set in the shell 1 of video camera
Portion, the shell have camera shooting trepanning 11 and light filling trepanning 12, including supplementary lighting sources 2 and variable-angle lens subassembly 3, supplementary lighting sources
2, variable-angle lens subassembly 3 and light filling trepanning 12, which are arranged in order, is set on a central axes, and the light of supplementary lighting sources 2 passes through
Variable-angle lens subassembly 3 is projected from light filling trepanning 12 carries out light filling, and variable-angle lens subassembly 3 has multiple focal length shapes
State.
Supplementary lighting sources, variable-angle lens subassembly and the light filling trepanning of variable-angle light compensating lamp provided in an embodiment of the present invention
It is arranged in order and offer light filling light on a central axes is provided, and variable-angle lens subassembly has multiple focal length states, when
When variable-angle lens subassembly is in different focal length states, light filling light differs by the back focal length of variable-angle lens subassembly
Sample, to provide the light fillings light such as focal length and wide-angle for video camera.Variable-angle light compensating lamp in the technical solution can be substantially
Degree reduces light filling cost, and improves the space occupancy rate of light compensating lamp in video camera.
In a specific embodiment of the invention, as shown in Fig. 2, the variable-angle lens subassembly of the variable-angle light compensating lamp
3 include light filling lamp housing 31, reciprocating member 32, lens 33 and at least one Fresnel Lenses 34, and lens 33 are set to benefit
31 middle part of light lamp housing, and 33 side face supplementary lighting sources 2 of lens, 33 other side face of lens are provided at least one Fresnel
Lens 34, at least one Fresnel Lenses 34 are connected with traverse member 32, and each Fresnel Lenses 34 is in traverse member 32
Driving under moved back and forth in the position of face lens 33 and the position of non-face lens 33.Fresnel Lenses appears as a piece of
There is the glass of countless multiple concentric circles lines (i.e. Fresnel zone).Equipment of many containing Fresnel Lenses all allows lamp in focus
It is moved forward and backward, to zoom in or out the size of light beam, because higher than the brightness through ordinary lens through its light, also due to
Brightness through its whole beam light at each position is all relatively uniform.
With reference to figure 3a, Fig. 3 b, Fig. 4 a and Fig. 4 b, the traverse member 32 of the embodiment of the present invention includes pulse motor, rocking bar biography
Motivation structure and switching switch, and pulse motor is connect by rocker transmission mechanism at least one Fresnel Lenses 34, switching switch
For startup and stop pulse motor, when pulse motor works, each Fresnel Lenses 34 is under the driving of pulse motor just
The position of lens described in the position of lens and non-face is moved back and forth and carries out varied angle light filling.Fresnel Lenses and ordinary lens
Traverse member driving periodical cover light filling trepanning so that variable-angle lens subassembly in multiple focal length states back and forth
Switching, to achieve the effect that multi-angle light filling, and reduces light filling cost and the space occupancy rate of light compensating lamp.Above-mentioned pulse electricity
Machine preferably uses magnet valve motor；Supplementary lighting sources include but not limited to infrared light light source, visible light source etc..
The basic functional principle of variable-angle lens subassembly in the embodiment of the present invention is：Light filling light is sent out by supplementary lighting sources
Beam, light filling light beam become focal length light filling light beam by lens.It is saturating by rocker transmission mechanism and pulse motor driving switching Fresnel
Mirror position makes the generation of light filling light beam become wide-angle light filling light beam by Fresnel Lenses or maintain it without Fresnel Lenses
Long defocused laser beam two states, and different wide-angle light filling light beams can also be generated using the Fresnel Lenses of multiple and different specifications.
