Description

Technical Field

[0001] This utility model relates to the field of teaching equipment, and in particular to a light decomposition and synthesis demonstration device. Background Technology

[0002] According to basic physics, sunlight and the white light from a flashlight are composed of various colors of light. When white light passes through a prism, it is refracted. Because different colors of light refract to different degrees, when white light passes through a prism, it produces seven colors of light: red, orange, yellow, green, blue, indigo, and violet. This is the decomposition of light. The three primary colors of light are red, green, and blue. These three primary colors can be combined to form white light, or they can be combined to form other colors of light; this is the synthesis of light.

[0003] Elementary school science is a comprehensive subject that primarily uses experiments as its medium, and appropriate teaching aids are a prerequisite for the effective implementation of experimental teaching. The elementary school science curriculum standards state that teachers should consciously and purposefully develop various elementary school science curriculum resources. Self-made teaching aids are an important component of these resources, and using suitable teaching aids to conduct experimental teaching can produce excellent teaching results. The decomposition and synthesis of light are fundamental concepts in the field of optics and are crucial for understanding the nature and properties of light.

[0004] However, the existing experimental equipment used to demonstrate the decomposition and synthesis of light is usually scattered and readily available, which often leads to the loss of equipment. When demonstrations or hands-on experiments are needed, it is often difficult to gather all the necessary equipment, which not only causes losses to the school's property, but also requires more students to share a set of equipment in order to allow all students to participate in the experiment. However, if more students share a set of equipment, it may not be possible for every student to participate in the experiment within the limited teaching time, which will inevitably reduce the effectiveness of experimental teaching.

[0007] The beneficial effects of this utility model are: when the light source mechanism and the prism mechanism are placed inside the light receiving and storage box, the light receiving and storage box can provide storage for the light source mechanism and the prism mechanism, thus preventing the light source mechanism and the prism mechanism from being lost; when the light source mechanism and the prism mechanism are placed outside the light receiving and storage box, the light receiving and storage box can directly receive the light emitted by multiple light source mechanisms, thereby performing a light synthesis demonstration, or receive the light refracted by the prism mechanism, thereby performing a light decomposition demonstration.

[0030] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] Example 1 This embodiment provides a light decomposition and synthesis demonstration device, characterized in that it includes: a light receiving and storage box 1, a prism mechanism 2, and a light source mechanism 3; the light source mechanism 3 and the prism mechanism 2 are placed inside the light receiving and storage box 1.

[0032] In this embodiment, when the light source mechanism 3 and the prism mechanism 2 are placed in the light receiving storage box 1, it is beneficial for the light receiving storage box 1 to provide storage for the light source mechanism 3 and the prism mechanism 2, and to prevent the light source mechanism 1 and the prism mechanism 2 from being lost.

[0033] Example 2 like Figure 1 As shown, this embodiment provides a light decomposition and synthesis demonstration device, characterized in that it includes: a light receiving and storage box 1, a prism mechanism 2, and a light source mechanism 3; the light source mechanism 3 and the prism mechanism 2 are placed outside the light receiving and storage box 1, and the light source mechanism 3, the prism mechanism 2, and the light receiving and storage box 1 are arranged in sequence at intervals; the light source mechanism 3 generates white light for demonstrating light decomposition.

[0034] In this embodiment, the light receiving and storage box 1 receives the light refracted by the prism mechanism 2, thereby demonstrating the decomposition of light.

[0035] Example 3 like Figure 2 As shown, this embodiment provides a light decomposition and synthesis demonstration device, characterized in that it includes a light receiving and storage box 1 and multiple light source mechanisms 3; the light source mechanisms 3 are placed outside the light receiving and storage box 1, and multiple light source mechanisms 3 are spaced apart, with the multiple light source mechanisms 3 spaced apart from the light receiving and storage box 1, and each emitting monochromatic light of a different color for demonstrating light synthesis.

[0036] In this embodiment, the light receiving and storage box 1 directly receives the light emitted by multiple light source mechanisms 3, thereby demonstrating the synthesis of light.

[0037] Preferred, such as Figure 1 and Figure 2 As shown in Embodiments 2 and 3, the light-receiving storage box 1 includes a box body 11 and a cover 12, with the opening of the box body 11 facing the prism mechanism 2 or the light source mechanism 3.

[0038] The advantages of adopting the above preferred solution are: the opening of the box faces the prism mechanism or the light source mechanism, which is conducive to the inner wall of the box directly receiving the light emitted by multiple light source mechanisms, thereby performing a light synthesis demonstration, or receiving the light refracted by the prism mechanism, thereby performing a light decomposition demonstration.

[0039] Preferred, such as Figure 1 and Figure 2 As shown, in Embodiments 1 to 3, one end of the cover 12 is hinged to the bottom end of the box body 11 on the opening side, and the other end of the cover 12 is separated from the top end of the box body 11 on the opening side, for demonstrating the decomposition or synthesis of light. Alternatively, the other end of the cover 12 is connected to the top end of the box body 11 on the opening side, for housing the light source mechanism 3 and the prism mechanism 2.

[0040] It should be noted that in Embodiment 1, when the other end of the cover 12 is connected to the top of the opening side of the box 11, the specific connection method can be various methods such as snap-fit, adhesive, or even abutment, as long as the opening of the box 11 can be closed and storage can be achieved.

[0041] The beneficial effect of adopting the above preferred solution is that one end of the cover is hinged to the bottom end of the box opening side, which facilitates the switching between the box storage function and the light-receiving function by separating or connecting the other end of the cover to the top end of the box opening side.

[0042] Preferred, such as Figure 2 As shown, in Embodiment 3, a light-displaying plate 13 is detachably provided on the inner wall of the box 11, and the light-displaying plate 13 is a circular white plate.

[0043] The advantages of adopting the above preferred scheme are: the light display panel is white as the background color, which is conducive to the synthesis of the three primary colors of light (red, green and blue) on the light display panel, thus facilitating the display of the synthesis effect; the light display panel is circular, which is conducive to adapting to the light spots of common light sources (flashlights) and provides a reference for adjusting the size of the light spot.

[0044] Preferred, such as Figure 3 As shown, in Embodiments 1 to 3, the prism mechanism 2 includes: a base 21, a support rod 22, an adjustment bracket 23, and a triangular prism 24. The top and bottom ends of the support rod 22 are fixedly connected to the adjustment bracket 23 and the base 21 respectively. The triangular prism 24 is rotatably installed in the adjustment bracket 23.

[0045] It should be noted that in Embodiments 1 to 3, the support rod 22 can be a telescopic rod in addition to being a rod of fixed length. The structure of the telescopic rod is the same as that of the telescopic structure of the umbrella handle, which can both adjust the length and provide stable support.

[0046] The advantages of adopting the above-mentioned preferred solution are: the base and support rod provide stable support for the adjustment of the prism, and the adjustment bracket allows the prism to rotate inside, thereby adjusting the prism to a suitable angle to participate in the light decomposition experiment.

[0047] Preferred, such as Figure 3 As shown, in Embodiments 1 to 3, the adjusting bracket 23 is a U-shaped plate with two hinge shafts 231 arranged opposite to each other on its top inner wall. One end of the hinge shaft 231 is fixedly connected to the top inner wall of the adjusting bracket 23, and the other end is rotatably engaged with the end of the triangular prism 24.

[0048] The advantages of adopting the above preferred solution are: the hinge shaft facilitates the rotation of the prism within the adjustment bracket to adjust the angle.

[0049] Preferred, such as Figure 3 and Figure 4 As shown, in Embodiments 1 to 3, fixing blocks 241 are fixedly installed at both ends of the prism 24. The side wall of the fixing block 241 is provided with a connecting hole, and the inner wall of the connecting hole is provided with an annular protrusion. The other side wall of the hinge shaft 231 is provided with an annular groove. The annular protrusion is adapted to be locked in the annular groove, so that the prism 24 can be fixed after rotating around the hinge shaft 231 to a preset angle.

[0050] It should be noted that in Embodiments 1 to 3, the rotatable snap-fit ​​structure of the annular protrusion and the annular groove is similar to the structure between a pen cap and a pen barrel in the prior art. It can be fixed by snap-fit ​​without affecting relative rotation. That is, the triangular prism 24 can rotate around the hinge axis 231 to a preset angle under the action of external force. When it is not subjected to external force and is only subjected to its own weight, because the friction between the annular protrusion and the annular groove is large and much greater than the weight of the triangular prism 24, the weight of the triangular prism 24 will not drive the triangular prism 24 to rotate, thereby fixing the preset angle after rotation.

[0051] The advantages of adopting the above preferred solution are: the annular protrusion is fitted and locked in the annular groove, which helps to fix the prism after rotation while the prism and the hinge shaft rotate relative to each other.

[0052] Preferred, such as Figure 1 and Figure 2 As shown, in Embodiments 1 to 3, the light source mechanism 3 includes a light source 31 and a light source bracket 32, and the light source 31 is rotatably mounted on the light source bracket 32.

[0053] The advantages of adopting the above preferred solution are: the light source can be rotatably mounted on the light source bracket, which is conducive to adjusting the incident direction of the light source, so that the light can enter the prism or directly hit the display plate inside the box.

[0054] Preferably, in Embodiments 1 to 3, the light source 31 is a zoom flashlight that emits white, red, green, or blue light.

[0055] It should be noted that in Embodiments 1 to 3, the zoom flashlight is existing technology, and its zoom principle and light source color will not be described in detail here.

[0056] The advantages of adopting the above-mentioned preferred scheme are: white light combined with a prism can be used to conduct light decomposition demonstration experiments; red, green and blue light are the three primary colors of light; after adjusting the size of the light spot, it is convenient to conduct light synthesis demonstration experiments by directly illuminating the light display board.

[0057] Preferred, such as Figure 5 As shown, in Embodiments 1 to 3, the light source bracket 32 ​​includes: a clamping plate 321, a connecting block 322, multiple support legs 323, and a universal ball joint 325. The clamping plate 321 is a U-shaped plate fixedly installed on the top of the universal ball joint 325. The light source 31 is clamped in the clamping plate 321. The universal ball joint 325 is rotatably installed on the top of the connecting block 322. The tops of the multiple support legs 323 are spaced apart and fixedly installed on the bottom of the connecting block 322. The bottom of the support legs 323 is fixedly fitted with an anti-slip sleeve 324.

[0058] It should be noted that in Embodiments 1 to 3, the anti-slip sleeve 324 is made of silicone, which helps to increase the friction with the surface of the experimental table and prevent the light source mechanism 3 from sliding on the surface of the experimental table. The rotational connection between the omnidirectional ball 325 and the top of the connecting block 322 is the same as the angle adjustment structure of the rearview mirror of the electric bicycle in the prior art. That is, the omnidirectional ball 325 can both adjust the angle at the top of the connecting block 322 and keep the adjusted angle fixed.

[0059] The advantages of adopting the above-mentioned preferred solution are: the connecting block and the universal ball make it easier to adjust the angle of the clamping plate and the clamped light source, thereby adjusting the incident angle of the light source; and the multiple legs and the anti-slip sleeve help to improve the stability of the light source support on the experimental table surface.

[0060] The working process of Examples 1 to 3 is described below: In Embodiment 1, when the light decomposition and synthesis demonstration experiment is not required, the prism mechanism 2 and multiple light source mechanisms 3 are placed inside the box 11, and the other end of the cover 12 is connected to the top of the opening side of the box 11 to close the opening of the box 11, providing storage for the prism mechanism 2 and multiple light source mechanisms 3 and preventing the prism mechanism 2 and multiple light source mechanisms 3 from being lost.

[0061] In Example 2, as Figure 1As shown, during the light decomposition demonstration experiment, the prism mechanism 2 and a light source mechanism 3 emitting white light are placed outside the box 11. The other light source mechanisms 3 are also removed from the box 11, so that the opening of the box 11 faces the prism mechanism 2. The box 11, prism mechanism 2 and light source mechanism 3 are arranged alternately. The universal ball 325 and the triangular prism 24 are rotated so that the white light emitted by the light source 31 enters the triangular prism 24 and the refracted light refracted out of the triangular prism 24 is directed to the inner wall of the box 11, and seven colors of light, namely red, orange, yellow, green, blue, indigo and violet, are displayed on the inner wall of the box 11.

[0062] In Example 3, as Figure 2 As shown, during the light synthesis demonstration experiment, three light source mechanisms 3, emitting red, green, and blue light respectively, are placed outside the box 11, and the prism mechanism 2 is also removed from the box 11, so that the opening of the box 11 faces the three light source mechanisms 3. The light spot sizes of the three light source mechanisms 3 are adjusted sequentially until they are equal to the light display panel 13. Then, the red, green, and blue light emitted by the three light source mechanisms 3 are sequentially directed onto the light display panel 13 and coaxially superimposed on the light display panel 13. Finally, the light display panel 13... The coaxial superimposed portion will appear white; or the size of the light spots of the three light source mechanisms 3 can be adjusted in sequence so that the light spot size is smaller than the display panel 13, and the red, green and blue light emitted by the three light source mechanisms 3 can be directed toward the display panel 13 in sequence and superimposed on the display panel 13 in a staggered manner. Finally, the superimposed portion of red, green and blue light on the display panel 13 will appear white, the superimposed portion of red and green light will appear yellow, the superimposed portion of red and blue light will appear magenta, and the superimposed portion of green and blue light will appear cyan.

[0063] This solution has the following advantages: 1. Using a strong flashlight and a larger prism makes the experimental phenomena more obvious; both the flashlight and the prism have stands, making it convenient for students to operate in a targeted manner; the vertical box mainly serves to block light, reducing the influence of external light sources on the experiment.

[0064] 2. Using red, green, and blue flashlights stacked together to demonstrate more intuitively that colored light can be mixed to form white light.

[0065] 3. The model is reasonably and stably designed, easy to operate and store, and uses readily available, energy-saving and environmentally friendly materials sourced from everyday life. Students learn while playing, enhancing their interest in learning.
