In addition, slit central point, the prism 8 of substrate center O, the slit central point of the 1st single patch 4, the 2nd single patch 5
The height such as central point be arranged, it can be ensured that light intensity.Because it is on the upper side that prism will cause light refraction, under imaging screen 7
The height such as side and the central point of prism 8 is arranged, in favor of observation.
In the utility model, four color LED light sources, snoot, V-type prism limiting slot and imaging screen are fixedly installed in case
Internal portion, position fixation is non-adjustable, also, the distance between each component and the parameters such as mounting height are in demonstration box production
The optimal parameter of completion has been debugged, so, teacher does not need to debug between each component when carrying out Demonstrator Trials using demonstration box
Distance and mounting height, that is, can guarantee refraction effect, have the advantages that easy to use.
A kind of refraction decomposition run demonstration box of light provided by the utility model, manufacturing process are as follows:
Step 1: determining four color LED light sources, snoot, the position of the 1st single patch 5 of single patch 4 and the 2nd and height.
By control button, the light source of corresponding color is selected；Light uses two single patch mistakes after snoot optically focused
Filter, it is ensured that the light angle of transmission is consistent.
Step 2: production V-type prism limiting slot, and determine the position of V-type prism limiting slot
V-type prism limiting slot is made, V-type prism limiting slot and prism fitting are close, as long as to guarantee prism
It is placed in limiting slot, the angles and positions of incident light are all unique, and debug incident angle, make to be ultimately imaged effect most
It is good；
Step 3: selecting suitable imaging screen position；
Imaging screen selects translucent sheet, to guarantee that portion, that is, Observable preferably reflects color imaging effect outside the enclosure；It adjusts
Suitable distance is tried, guarantees that imaging effect is clear, various colors refraction angle differs greatly；According to experimental verification, 3W lamp bead is
Substantially it can satisfy in classroom and demonstrate, school can be clearly visible imaging effect after anaclasis.
Step 4: control button, two single patch, V-type prism limiting slot, imaging screen positions are being debugged by light source
Position it is fixed after, outside is made into closed case (ambient is avoided to interfere), and box side is made into movable open state, with
Just student opens side plate observation internal structure and optical path, while prism being facilitated to pick and place.In specific implementation, each component and cabinet it
Between can be connected fixed form using screw epoxy glue.
A kind of refraction decomposition run demonstration box of light provided by the utility model, application method are as follows:
Step 1, determines whether this test needs to install prism, if it is not required, then case side plate is opened, from V-type three
Prism is taken out on prism limiting slot；
Step 2, by the selection of switching switch, this tests the lamp bead color for needing to use, for example, selection feux rouges lamp bead；
When not installing prism, the feux rouges that feux rouges lamp bead issues passes sequentially through snoot, the 1st single seam of single patch the 4, the 2nd
After piece 5, it is imaged on imaging screen；Outside the enclosure face observe imaging screen, read corresponding scale, record this test at image position
It sets；Through testing, when no placement prism, 4 kinds of coloured light can be checked respectively, it is consistent in imaging screen imaging position.
Step 3 is switched by switching, selects the lamp bead of its allochromatic colour to carry out refraction test, and record imaging position；
Then, case side plate is opened, prism is installed, after then carrying out a batch installation prism again, various colors lamp bead
Refraction, and the imaging position of various different colours lamp beads is recorded respectively.
It is thus achieved that same color lamp bead whether by prism refraction imaging position comparative test, and,
Imaging position comparative test of the different colours lamp bead after prism reflects.It can be repeated as many times and demonstrate.
