NightStar Flashlight Physics Guide

NightStar Flashlight Physics Guide. This informative publication is a gateway into the physics of renewable energy systems. Specifically, how the Laws of magnetism, energy storage, and light refraction and reflection come together to make a shake flashlight.

Through various lessons, the NightStar Physics Guide demonstrates the Principles of Newtonian Relativity, Faraday’s Law of Electromagnetic Induction, Snell’s Law of Refraction and Fermat’s Principle of Least Time.

Educators teach these principals by selecting lessons, in combination with a Shake Light 40 LED Flashlight, to demonstrate physics impact upon our renewable energy world.

The Physics Behind the NightStar Shake Flashlight

NightStar Flashlight Physics Guide showcases calculations and diagrams detailing engineering elements integrated into a NightStar flashlight. Written for students in Grade 9 and above, the guide shows how magnetism, electrodynamics, energy, light and optics come together to construct a rechargeable light that operates for years.

NightStar Flashlight Physics Guide – Publication Snippet

Many of the components and mechanisms of the NightStar flashlight aptly demonstrate the importance of physics principles. The repulsion of the mobile magnet by the two fixed end magnets illustrates ferromagnetism. The generation of alternating electric current in the coil by the charging magnet demonstrates magnetomotive induction.  The alternating electric current converted to direct or unidirectional current shows diode rectification.

Energy conveniently saved for later use demonstrates capacitive energy storage. This energy carried in an electric current converts to blue light demonstrating radiative recombination in a light-emitting diode. Phosphor conversion of blue light into other colors, illustrates fluorescence. Finally, the white light streaming in all directions is collected and projected forward into a useful beam by the reflector and lens demonstrates reflection and refraction, respectively.
