Description of drawings
This rear view for invention of Fig. 1;
Fig. 2 is front view of the present invention.
Embodiment
For the ease of those skilled in the art's understanding, the present invention is further illustrated below in conjunction with specific embodiment:
As depicted in figs. 1 and 2, a kind of teaching stroboscopic light source, comprise casing, described casing is provided with supply unit 1 and power switch 2, power switch can be arranged on different local with supply unit as required, described casing front end is provided with pulse xenon lamp 3, and described box back is provided with the synchronous input interface 4 of light-operated startup flash of light.The needs of taking for the moving object of satisfying different acceleration magnitude, make the flashlamp frequency adjustable, be provided with frequency control apparatus in the described casing, described box back middle part is provided with display panel 5, described display panel 5 right sides are provided with frequency adjustment 6, described frequency control apparatus is connected with pulse xenon lamp 3, display panel 5, frequency adjustment 6 respectively, and described display panel 5 also can be located at other positions as required.Described frequency control apparatus is single-chip microcomputer.In order to realize that digital camera is taken, the teaching stroboscopic light source glistens, the synchro control of moving object action, described display panel 5 belows are provided with synchro source 7.Described synchro source 7 left sides are provided with synchro switch 8.Described supply unit 1 is accumulator.Be provided with protective device in the casing, described display panel 5 right sides are provided with the protection pilot lamp 9 that links to each other with protective device.Described display panel 5 left sides are provided with start key 10.Described display panel 5 is the LED panel, and described casing lower end is provided with fixed mount.。For the shooting effect that guarantees, shown in the flash of light light duration 2mS ± 0.5mS.
During work, to there be the camera of flashlamp to be fixed on the tripod, the teaching stroboscopic light source is fixed on another tripod, stroboscopic light source is apart from movement of falling object object 2m～3m being shot, pulse xenon lamp is aimed at moving object being shot, mixes up focal length, time shutter and the selection aperture F6～F10 of camera.The synchro source output of stroboscopic light source is connected on the electromagnet of freely falling body, connects the power supply of stroboscopic light source, and the iron ball on the freely falling body holds.Light-operated probe connecting line plug inserts the synchronous input interface of stroboscopic light source, and light probe is apart from freely falling body 10cm～50cm, and height is at the freely falling body medium position.According to the acceleration of motion of freely falling body object, the flashing rate of stroboscopic light source is adjusted to 30.0Hz.After finishing above step, press the shutter of camera, the flashlamp flash of light on the camera starts the pulse xenon lamp flash of light of stroboscopic light source, and when pulse xenon lamp began to glisten, the iron ball on the freely falling body broke away from electromagnet synchronously.Pulse xenon lamp is by extinguishing automatically behind the 30Hz frequency group flashing light 16 times and entering guard mode, and guard lamp is bright, guard time 60S ± 5S.After shooting was finished, if the movement of falling object track of taking is clear inadequately, by the guide number GN24 of this stroboscopic light source pulse xenon lamp, namely guide number GN photographic lens F number and pulse xenon lamp were to the product of the distance L between the subject, i.e. GN=FL.Change the aperture of camera or change the stroboscopic light source pulse xenon lamp and the distance of movement of falling object object being shot, take again by above step.
