Abstract
maturation a blowtorch usually involves, to some extent, a tradeoff between its effective brightness and the extent of battery life. The push provided by the battery is not only used by the light source: Some of this energy is wasted in the form as heat as well. The traditional blowlamp generates a high amount of heat in rest to the amount of light it produces. This amount of wasted heat energy, in effect, reduces extent of battery life.
This report discusses the design a flashlight that is more energy efficient than the traditional flashlight. This design pull up stakes produce a flashlight that can provide lighting, at higher intensity than the traditional flashlight, which lasts for six hours at uttermost brightness, as well as an emergency flash mode. This device contains two main components: (1) The design of the flashlight circuit, with options for both entire power mode and emergency mode, (2) The design of a battery charger that will be used to charge the rechargeable batteries used with the flashlight.
