Problems solved by technology

The original teaching tools are labor-intensive when demonstrating the synthesis of light, and the teaching effect is not good.
In order to demonstrate the luminous device to students, the metal sulfide phosphors coated on windmill blades in the past have low afterglow brightness and short afterglow time, which is only tens of minutes. Students often cannot clearly see the luminous effect on teaching tools coated with phosphors.

Embodiment 1

[0014] Sunlight irradiates the solar cell 2 on the base 1 of the luminous device 12 installed on the solar photovoltaic windmill, the solar cell 2 generates direct current, and the direct current passes through the conductive wire 5 and the circuit switch 3 to input two LED spotlights 6 with a power of 3 watts on the left and right. , the LED spotlight 6 emits a bright light beam, and the light beam illuminates the windmill blades 8, and the 8 luminous garden spots 11 distributed on each windmill blade 8 can absorb natural light and artificial light due to being coated with long afterglow luminescent materials, and store them Light energy, stable and efficient emission of various colors of light for 11 hours in a dark environment, so as to achieve power-saving luminescence.

Embodiment 2

[0016] Sunlight irradiates the solar cell 2 on the base 1 of the luminous device 12 installed on the solar photovoltaic windmill, the solar cell 2 generates direct current, and the direct current is input to the left and right two LED spotlights 6 with a power of 6 watts through the conductive wire 5 and the circuit switch 3 , the LED spotlight 6 emits a bright light beam, and the light beam illuminates the windmill blades 8, and the 16 luminous garden spots 11 distributed on each windmill blade 8 can absorb natural light and artificial light because they are coated with long afterglow luminescent materials, and store them Light energy, stable and efficient emission of various colors of light for 20 hours in a dark environment, so as to achieve power-saving luminescence.

Abstract

The invention relates to a noctilucent device on a solar photovoltaic windmill, belonging to the technical field of new energy source educational affiliation. Sunlight irradiates solar battery arranged on the base of the noctilucent device on the solar photovoltaic windmill to generate direct current; part of the direct current is input into an LED spot light through a circuit switch and a conductor wire; the light emitted from the LED spot light illuminates windmill vanes, wherein noctilucent round spots distributing on the windmill vanes are coated with long-afterglow luminous material which can absorb natural light and artificial light and save optical energy so that lights of various colors can be emitted in a darker environment stably and efficiently; the other part of direct current is input into a direct current motor to through an electric lead inside a hollow tube to convert electric energy to mechanical energy and drive the windmill vanes respectively coated with seven colors including red, orange, yellow, green, blue, indigo-blue and purple on the surface of the vanes to rotate at high speed so as to synthesize white light, and a photosynthesis experiment can be demonstrated to students. Moreover, fixed screws are used for assembling or disassembling the windmill vanes, and the direct current can also be input into a lithium ion battery to be stored for later use.

Description

technical field [0001] The invention relates to a luminous device on a solar photovoltaic windmill, which belongs to the technical field of new energy teaching appliances. Background technique [0002] When explaining the course of optical principles, the teacher will take out a prism to demonstrate that the white sunlight passes through the prism. Due to the different refractive index, the monochromatic light will be separated to form seven colors of red, orange, yellow, green, blue, indigo and purple. That is dispersion. The teacher will take out a circular plate painted in seven colors of red, orange, yellow, green, blue, indigo and purple, install it on a base with a hand-cranked handle, and call a student to use it on the podium. Shake the turning handle with your hands, and drive the circular plate to rotate around the center of the circle at a high speed. Students with weak strength can’t turn it fast, and students in the audience can still see the lights of seven co...
