The specific implementation mode is as follows:
the core of the invention is to provide a light source teaching aid, which solves the problem of poor interactivity of the existing teaching aid.
In order that those skilled in the art will better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, in a specific embodiment, the light source teaching aid provided by the invention includes a first heart-shaped lamp 1, where the first heart-shaped lamp 1 includes a first small circuit board 5, a first switch 3, a led lamp 2, and a second heart-shaped lamp 6, where the second heart-shaped lamp 6 includes a first large circuit board 7, the first heart-shaped lamps 1 are distributed on the first large circuit board 7 in a heart shape, and the first heart-shaped lamp 1 is detachably mounted on the first large circuit board 7. Like this can directly use big circuit board at mr's demonstration formula, when arriving the classmate experiment, can dismantle the exclusive use of getting off, interactive strong and more pleasing to the eye. A second switch 10 may also be included, which controls half of the lights.
Preferably, the device also comprises a convex lens, a light screen 8 and a toughened glass film, when the 'convex lens imaging rule' is demonstrated, the second heart-shaped lamp 6 in the interactive demonstration experiment is in a peach heart shape, and the farther the distance is, the smaller the heart received by the lens 9 is. Performance of the first heart-shaped lamp 1 in the grouping experiment: when the light spots constituting the heart shape on the light screen of the light screen 8 are clearly visible, data can be read.
The first heart-shaped lamp also comprises a base 4 which can be independently stood on a desktop, and when plane mirror imaging law is demonstrated, the first heart-shaped lamp not only serves as a high-quality light source in an experiment exploring convex lens imaging law, so that the grouping experiment effect is more obvious, but also is the most important prop in an interactive demonstration experiment of a teacher. The experimental teaching aid is an important engine for teaching and propelling of the whole experimental class and is also a natural link for interaction between teachers and students. The led lamps 2 are single point lamps and are distributed on the first small circuit board 5 in a heart shape.
In addition, the LED lamp 2 is a strip lamp which is heart-shaped, and other common light sources are all in the protection range,
preferably, the power supply used by the first heart-shaped lamp 1 is a lithium battery, the lithium battery is selected, the design is optimized, the problems of frequent battery replacement and unstable voltage are solved, and the imaging effect is better.
