Abstract
The utility model relates to an illumination device of a vehicle-mounted holder camera, which comprises a laser transmitter, an optical fiber and a zoom lens, wherein the laser transmitter is fixed in a base of a holder substrate; the zoom lens is fixed in an outer shell of the camera; the optical fiber is connected with the laser transmitter and the zoom lens for transmitting a signal of the laser transmitter to the zoom lens; and the side surface of a ball cover of the outer shell of the camera is provided with a plurality of light holes. The optical fiber guides laser beam generated by the laser transmitter into the zoom lens, and the zoom lens guides the laser beam out of the light holes on the outer shell of the camera, so that the illumination device has large luminance, good night luminous effect and small heat productivity, and reduces the influence of the heat quantity generated by infrared ray to the camera in the prior art.
Description
Technical field
The utility model relates to the accessory of vehicle-mounted monopod video camera, designs a kind of lighting device of vehicle-mounted monopod video camera especially.
Background technology
Vehicle-mounted monopod video camera belongs to the front end device that safety-protection system is gathered vision signal, can be widely used in various occasions such as cell environment monitoring, square monitoring and road monitoring in supervision of the cities in a large number.
Chinese patent literature CN 201257937Y disclosed " a kind of vehicle-mounted monopod video camera ", include The Cloud Terrace, be fixedly installed in the video camera of The Cloud Terrace one side, this side of installing at video camera also is equipped with unglazed sudden and violent infrared lamp synchronously, and the opposite side of The Cloud Terrace is equipped with illumination search lamp.Its night vision illumination adopts infrared technique, problems such as the thermal value of existence is big, illumination distances deficiency, and the illuminator structure complexity is light inadequately simultaneously.
The utility model content
The purpose of this utility model is to provide the lighting device of the vehicle-mounted monopod video camera that a kind of thermal value is little, illumination distances is enough, volume is little.
The technical scheme that realizes the utility model purpose is a kind of lighting device of vehicle-mounted monopod video camera, comprises generating laser, optical fiber and zoom lens; Described generating laser is fixed in the base of The Cloud Terrace pedestal; Described zoom lens is fixed in the video camera outer cover; Described optical fiber connects generating laser and zoom lens, and the signal of generating laser is transferred to zoom lens; The side of the ball cover of described video camera outer cover is provided with a plurality of unthreaded holes.
Described zoom lens and the video camera synchronous zoom that is fixed in the video camera outer cover.
Unthreaded hole on the every ball cover of described video camera outer cover has 4, is evenly distributed on the side of ball cover.
The utlity model has following beneficial effect: the utility model adopts the laser beam illumination, by optical fiber the laser beam that generating laser produces is guided in the zoom lens, to draw the unthreaded hole of laser beam from the video camera outer cover by zoom lens again, brightness is big, night illumination is effective, and thermal value is little, has reduced the influence of the heat of infrared ray generation in the past to video camera.Simultaneously, zoom lens and video camera synchronous zoom can make illumination distances and camera distance mate mutually, guarantee the effect of monitoring.In addition, the unthreaded hole that distributes on the ball cover has 4, and it is more even so just laser-beam divergence to be got, and obtains better night illumination effect.

Embodiment
(embodiment 1)
See Fig. 1 to Fig. 4, present embodiment comprises generating laser 1, optical fiber 2 and zoom lens 3.
Generating laser 1 is fixed in the base 41 of The Cloud Terrace pedestal 4.Optical fiber 2 connects generating laser 1 and zoom lens 3, and the signal of generating laser 1 is transferred to zoom lens 3.The side of the ball cover 51 of video camera outer cover 5 is provided with 4 unthreaded hole 51-1.Zoom lens 3 and video camera 6 synchronous zoom that are fixed in the video camera outer cover 5.
See Fig. 1, two back up pads 42 of the The Cloud Terrace pedestal 4 of vehicle-mounted monopod video camera are positioned at base 41 upper ends and are oppositely arranged; Two back up pads 42 are respectively equipped with relative transmission gear 42-1 and follower gear 42-2; Two back up pads 42 also are respectively equipped with the cover plate 45 that covers transmission gear and follower gear; Be provided with the centre bearing 41-3 that horizontally rotates motor 41-1, vertical rotation motor 41-2 and be positioned at base 41 centers in the base 41.Centre bearing 41-3 and base 41 are rotationally connected, and horizontally rotate motor 41-1 and drive centre bearing 41-3 rotation by horizontal driving belt 43, and vertical rotation motor 41-2 drives transmission gears 421 by vertical driving belt 44 and rotates.See Fig. 2 to Fig. 4, also be provided with back up pad 42 on the The Cloud Terrace pedestal, be used for 4 sealings of The Cloud Terrace pedestal.
By optical fiber 2 laser beam that generating laser 1 produces is guided in the zoom lens 3, to draw the unthreaded hole 51-1 of laser beam from video camera outer cover 5 by zoom lens 3 again, zoom lens 3 and video camera 6 synchronous zoom can make illumination distances and camera distance mate mutually, guarantee the effect of monitoring.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
