Abstract
A kind of teaching demonstration device of light penetration power test.It is made up of locellus light box, top cover, middle part draw-in groove, bottom draw-in groove, photo-sensitive cell, display screen, measured matter, screw rod, single plane light source, index dial, CD driver type transmission grillage, carrier plate, support, dividing plate and dimmer, this experimental provision can by experimental data reflection on a display screen, can allow student understand the impact of various factors on light penetration power power intuitively.And this experimental provision is not only by regulating the power of light to study the impact of light intensity on light penetration power; Also by replacing the measured matter research measured matter of different-thickness and material to the impact of light penetration power; Or by adjustable screw bar, the distance changed between single plane light source to measured matter studies its impact on light penetration power.This principle of device is simple, easy to operate, meets current teaching demand, significant.
Description
Technical field
The utility model relate to a kind of apparatus for demonstrating, the teaching demonstration device of particularly a kind of light penetration power test.
Background technology
Light is really present in each corner in our daily life, along with going deep into of studying light, the place that light is useful and harmful place are also at leisure known by people, and then people start to learn to replace original glass as window with a little specific material, the clothes even dressing special fabric manufacture irradiates to reduce light the harm caused human body.
At present, we are only limitted on books for understanding and grasping of light penetration ability relevant knowledge, and lack teaching demonstration device, therefore we cannot have a better understanding light penetration ability.Of the present utility model providing can meet current teaching demand, can visually for student shows the penetration capacity of light in different medium, significant.
Summary of the invention
For the problems referred to above, the teaching demonstration device that the utility model provides a kind of light penetration power to test, better reaches teaching purpose, the penetration capacity of understanding light in different medium making student more vivid.
The utility model solves the technical scheme that its technical matters adopts: it is made up of locellus light box, top cover, middle part draw-in groove, bottom draw-in groove, photo-sensitive cell, display screen, measured matter, screw rod, single plane light source, index dial, CD driver type transmission grillage, carrier plate, support, dividing plate and dimmer, single plane light source is connected to the below of top cover by screw rod, and top cover is installed on the top of locellus light box; Support is that cross type is connected in CD driver type transmission grillage, and CD driver type transmission grillage is divided into four regions; Dividing plate is that the corresponding CD driver type transmission grillage inner support position of cross type is fixed in locellus light box, locellus light box is divided into four separate space; Measured matter is positioned in four regions of CD driver type transmission grillage; Middle part draw-in groove is positioned at below screw rod, above four separate space of dividing plate; The CD driver type transmission grillage that measured matter is housed is positioned in the middle part draw-in groove of locellus light box; Photo-sensitive cell is arranged on the position corresponding to carrier plate below each separate space center; Photo-sensitive cell carrier plate is housed to be positioned in the bottom draw-in groove of locellus light box; Display screen is positioned over the side of locellus light box; Dimmer is positioned over the another side of locellus light box.During test, reflect the impact of various factors on penetration power by the data of observing light intensity on display screen, in addition, do not use when top cover and single plane light source and can be used for detecting natural light to the impact of measured matter penetration power, finally reach the object of teaching demonstration.
The beneficial effects of the utility model are: by experimental data reflection on a display screen, student can be allowed intuitively to understand the impact of various factors on light penetration power power.And this experimental provision is not only by regulating the power of light to study the impact of light intensity on light penetration power; Also by replacing the measured matter research measured matter of different-thickness and material to the impact of light penetration power; Or by adjustable screw bar, the distance changed between single plane light source to measured matter studies its impact on light penetration power.This principle of device is simple, easy to operate.
