Novel rotating colored lantern

Abstract

The invention discloses a novel rotating colored lantern comprising a cylinder body containing colorless liquid; reflective lenses, and a polyhedron for reflecting monochromatic lights; the reflectivelenses reflect monochromatic lights onto the polyhedron. The novel rotating colored lantern further comprises a motor that drives the rotation of the polyhedron, a ring lamp that provides the light source, and an adjustment mechanism that adjusts the illuminating lens. The sunlight or light is decomposed into monochromatic lights through the colorless liquid and the reflective lenses, and the monochromatic lights are irradiated onto the polyhedron and reflected to the periphery and the motor drives the polyhedron to rotate, therefore dynamically changing the angle between the reflector and the monochromatic light of each color; It is like a rotating colored lantern in ballrooms that emits colorful light, which is very beautiful, ornamental and interesting. At the same time, it can attractstudents' interest in learning optical and deepen the understanding and mastery of optical knowledge.

Description

technical field [0001] The invention belongs to the field of handicrafts, and in particular relates to a novel rotating colored lamp. Background technique [0002] It is well known that when light passes through different media, it will be refracted. The smaller the wavelength of monochromatic light is, the greater its relative refractive index will be. The relative refractive index of the colored light is different, and the polychromatic light will be decomposed into corresponding monochromatic lights of different colors. For example, sunlight is composed of red, orange, yellow, green, blue, indigo, and violet, and the refractive index of red, orange, yellow, green, indigo, and violet becomes larger in turn. Therefore, when sunlight passes through a wedge-shaped transparent object, the sunlight is decomposed into brilliant red. Orange, yellow, green, blue, indigo, and violet are connected sequentially with seven colors of light (referred to as seven-color light), which is ...

AI Technical Summary

Problems solved by technology

At present, there is no corresponding device that uses the seven-color light that sunlight is decomposed to enhance viewing and interest, and there is no experimental device that uses wedge-shaped transparent objects to decompose sunlight. Students are limited to book learning, and there are few practical operations. not conducive to deepening understanding
