Abstract
The invention discloses a convex lens imaging experiment device and relates to the technical field of manufacturing of teaching aids. The convex lens imaging experiment device comprises an optical bench, a convex lens and an optical screen, wherein the optical bench is provided with a sliding rod arranged on supports and a plurality of sliding seats arranged on the sliding rod; the convex lens is mounted on one of the sliding seats; the sliding rod is respectively provided with the optical screen and an electronic candle on the sliding seats on the two sides of the convex lens. Compared with the prior art, the invention can solve the problems that a light source used in an convex lens imaging experiment is the candle and can pollute indoor air, and the light source stability is poor.
Description
Technical field
The present invention relates to teaching aid manufacturing technology field, especially a kind of device for convex lens experiment.
Background technology
Convex lens experiment is important physical experiment in middle school teaching material, and its experiment purpose is by the imaging law by the cognitive convex lens of specific teaching equipment guiding student.Current convex lens experimental provision forms primarily of optical bench and convex lens, light source and the optical screen be located on described optical bench.During experiment, place light source and optical screen respectively in the both sides of convex lens, by mobile light source or the optical screen distance relative to convex lens, make light source become on optical screen clearly as.Front in teaching, light source used is generally candle, uses candle to be that light source exists following deficiency: 1, will pull on curtain of classroom because of experiment, the gas that candle combustion produces and the black smoke of emerging, can pollute room air; 2, candle candle flame is in atmosphere exposed, and be subject to airflow influence and rock, light source stability is poor, and the height of picture of cause lighting up flame and candle flame is not easy to measurement, the most clearly as position not easily determine; 3, the paraffin dropping in desktop and ground is difficult to cleaning.
Summary of the invention
Problem solved by the invention is to provide a kind of convex lens experimental provision, can pollute the problem of room air and light source stability difference to solve existing Physical Experiment light source used for candle.
In order to solve the problem, the technical solution used in the present invention is: this convex lens experimental provision comprises optical bench, convex lens and optical screen, described optical bench has the slide bar be located on bearing and the multiple slides be located on described slide bar, a described slide is equipped with described convex lens wherein, described slide bar is equipped with optical screen and electric candle respectively on the described slide of described convex lens both sides.
In above-mentioned convex lens experimental provision technical scheme, technical scheme can also be more specifically: described electric candle includes candle body, at described candle body built with a core body, the chamber laying battery is provided with in described core body, spring is provided with in the bottom of described chamber, be provided with the lamp socket by conductor block and described chamber at the top of described core body, described lamp socket is equipped with the candle lamp stretching out described candle body; Described core body is connected with described slide by the screw rod being located at bottom.
Further: to be provided with battery cover at the sidewall of described core body; Described candle lamp is red LED.
Further: described slide bar is two, the two ends of two described slide bars are inserted on described bearing respectively, and described bearing is provided with the scale be set in parallel with described slide bar.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, because light source is electric candle, good many disadvantages of having avoided using candle as light source, and select people's naked eyes than more sensitive red light source, the picture that optical screen presents is clear especially, light source stability is good, and teaching demonstration is effective; 2, electric candle, convex lens and optical screen all can slide on slide bar, add the interest of teaching demonstration.
