Further, described casing lower end is provided with fixed mount.
By implement the present invention can obtain following Advantageous Effects: can with all have the digital camera of flashlamp to realize digital camera is taken, stroboscopic light source flash synchronization of imparting knowledge to students controls, improve the compatibility of teaching stroboscopic light source, realize flashing rate continuously adjustabe simultaneously, meet the needs that the moving object of different acceleration magnitude is taken.
Accompanying drawing explanation
Fig. 1 is originally the rear view of invention;
Fig. 2 is front view of the present invention.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment, the present invention is further illustrated:
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 and supply unit can be arranged on Bu Tong local as required, described casing front end is provided with pulse xenon lamp 3, and described box back is provided with the light-operated synchronous input interface 4 starting flash of light.The needs taken are carried out in moving object in order to satisfied different acceleration magnitude, make flashlamp frequency-adjustable, frequency control apparatus is provided with in described casing, display panel 5 is provided with in the middle part of described box back, frequency adjustment 6 is provided with on the right side of described display panel 5, 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 the synchro control of digital camera shooting, the flash of light of teaching stroboscopic light source, moving object action, below described display panel 5, be provided with synchro source 7.Synchro switch 8 is provided with on the left of described synchro source 7.Described supply unit 1 is accumulator.Be provided with protective device in casing, on the right side of described display panel 5, be provided with the protection pilot lamp 9 be connected with protective device.Start key 10 is provided with on the left of described display panel 5.Described display panel 5 is LED panel, and described casing lower end is provided with fixed mount.。In order to the shooting effect ensured, shown flash of light light duration 2mS ± 0.5mS.
During work, be fixed on tripod by there being the camera of flashlamp, teaching stroboscopic light source is fixed on another tripod, stroboscopic light source is apart from movement of falling object object 2m ~ 3m being shot, moving object being shot aimed at by pulse xenon lamp, mixes up the focal length of camera, time shutter and selection aperture F6 ~ F10.The synchro source of stroboscopic light source exports and is connected on the electromagnet of freely falling body, and connect the power supply of stroboscopic light source, the iron ball on freely falling body holds.Light-operated probe cable 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 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 completing above step, press the shutter of camera, the flash fire on camera starts the pulse xenon lamp flash of light of stroboscopic light source, and while pulse xenon lamp starts flash of light, the iron ball on freely falling body synchronously departs from electromagnet.Pulse xenon lamp is by automatic distinguishing after 30Hz frequency group flashing light 16 times and enter guard mode, and guard lamp is bright, guard time 60S ± 5S.After having taken, if the movement of falling object track of shooting is clear not, by the guide number GN24 of this stroboscopic light source pulse xenon lamp, the product of the distance L namely between guide number GN photographic lens F number and pulse xenon lamp to subject, i.e. GN=FL.Change the aperture of camera or change the distance of stroboscopic light source pulse xenon lamp and movement of falling object object being shot, again taking by above step.
By implement the present invention can obtain following Advantageous Effects: can with all have the digital camera of flashlamp to realize digital camera is taken, stroboscopic light source flash synchronization of imparting knowledge to students controls, improve the compatibility of teaching stroboscopic light source, realize flashing rate continuously adjustabe simultaneously, meet the needs that the moving object of different acceleration magnitude is taken, make Whole Equipment usable range wider.
The foregoing is only specific embodiments of the invention, but technical characteristic of the present invention is not limited thereto, any those skilled in the art is in the field of the invention, and the change done or modification are all encompassed among the scope of the claims of the present invention.
