Abstract
The utility model relates to a zoom illumination device matched with a zoom video camera, which comprises a lamp tube 1, an optical zoom element 2 and a zoom control device 6, wherein the zoom control device 6 comprises an operational control circuit 4 and a motor 5; a signal input end of the operational control circuit 4 is connected with a zoom signal control end of the zoom video camera; an output end of the operational control circuit 4 is connected with an input end of the motor 5; a signal feedback end of the motor 5 is connected with an input end of the operational control circuit 4; the motor 5 drives the optical zoom element 2 to move from front to rear. The zoom control device of the illumination device controls the optical zoom component to move from front to rear and zoom by extracting the zoom signal parameters of the zoom video camera; thus, scenes shot by the zoom video camera obtain enough light rays; the quality of shot images is effectively ensured.
Description
1, technical field:
The utility model relates to the zooming illuminating apparatus that cooperates with Zoom camera.
2, background technology:
At present, the general illumination device is all the fixed transmission angle, when with the collocation use of Zoom camera system, then can not make system be at any time in the optimal illumination effect.When taking scenery far away and taking near scenery, the light that lighting device sends shows power and differs, the quality that influence is taken.As Fig. 1, Fig. 2, shown in Figure 3, there is the control standard of multiple zoom in present Zoom camera, simulation, numeral is arranged and mix standard.
3, summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides the zooming illuminating apparatus that cooperates with Zoom camera, and lighting device guarantees the abundance of light with the together zoom of Zoom camera, guarantees the quality of taking.
The utility model is achieved by the following technical solution: it comprises fluorescent tube and focus optical element, it also comprises the zoom control device in addition, this zoom control device comprises arithmetic control circuit and motor, the signal input part of arithmetic control circuit is connected with the zoom signal control end of Zoom camera, the output terminal of arithmetic control circuit is connected with the input end of motor, the signal feedback end of motor is connected with the input end of arithmetic control circuit, and the zooming motor driver optical element moves forward and backward.
Be provided with the coding and decoding circuit between the zoom signal control end of the signal input part of above-mentioned described arithmetic control circuit and Zoom camera.
Above-mentioned described motor can be stepper motor or common electric machine.
Above-mentioned described focus optical element is a variable focus lens package.
Above-mentioned described focus optical element is a concave mirror.
The utility model compared with prior art has following advantage: by extracting the zoom signal parameter of Zoom camera, the zoom control device control focus optical element of lighting device moves forward and backward synchronous zoom, the scenery that Zoom camera is taken obtains enough light, effectively guarantees to take the quality of image.
