Description
Technical field
The utility model belongs to a kind of experimental provision, particularly a kind of device of ability of inspected object reflection ray.
background technology
When the reflected content of current school science teaching light, in teaching process, teacher normally adopts the method for demonstration, carries out the reflective explanation of object, so just cause student on classroom, Perceptual observation usually can only be adopted to be different to understand the reflecting power of object.Such observation often naked eyes to carry out the resolution of science, textbook or otherwise knowledge many times can only be relied on to supplement, for the instrument reflection society of light having had professional detection light, but price high, operate strongly professional, be unfavorable for that pupil uses.
Utility model content
The purpose of this utility model is to solve the problem, and proposes a kind of object reflecting power detecting device, this object reflecting power detecting device have design science, rational in infrastructure, simple to operate, measure accurate feature.
The purpose of this utility model is achieved through the following technical solutions: object reflecting power detecting device, be provided with base plate, four support columns are provided with below described base plate, it is characterized in that: described base plate one end is provided with a riser, the top of described riser is equipped with a snoot, the middle part of described riser is provided with a light source, the top of described riser is provided with one piece of photoelectric cell, described light source passes through light source switch, wire is connected with powered battery, the middle part of described base plate is provided with a reflective target object, the other end of described base plate is provided with one piece of voltage table and one group of LED light emitting diode respectively, described photoelectric cell by wire respectively with voltmeter switch, voltage table and diode switch, one group of LED light emitting diode is connected.
Further, described light source adopts the one in incandescent lamp, daylight lamp, LED spotlight.
The light that the utility model utilizes electric-torch burner to send, is reflected on photoelectric cell and is converted into electric energy.Because intensity of reflected light is different, the voltage produced is different, finally show LED lighting brightness and voltage table registration difference, solve student the reflection knowledge of light can only passively be accepted, the problem that can not deeply probe into, it not only can allow student utilize object reflects light to make photoelectric cell send electric energy, the brightness of light emitting diode difference is made to distinguish the reflecting power (qualitative observation) of object, also voltage table numerical value can be utilized to carry out quantification observe, voltage table can help child to be familiar with the change of trickle reflected value more accurately simultaneously.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is theory structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1, 2, object reflecting power detecting device, be provided with base plate 1, four support columns 2 are provided with) below described base plate, described base plate one end is provided with a riser 3, the top of described riser is equipped with a snoot 4, the middle part of described riser is provided with a light source, the top of described riser is provided with one piece of photoelectric cell 6, described light source passes through light source switch, wire is connected with powered battery, the middle part of described base plate is provided with a reflective target object 7, the other end of described base plate is provided with one piece of voltage table 8 and one group of LED light emitting diode 9 respectively, described photoelectric cell by wire respectively with voltmeter switch 10, voltage table and diode switch 11, one group of LED light emitting diode is connected, described light source adopts incandescent lamp.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
