For me, the main purpose of the flashlight is to help me in my favorite outdoor activities like hiking, trekking, and camping and therefore, this is the flashlight I would buy, which is known as the ‘Headlamp’! A headlamp is a wearable flashlight affixed to your head so that you can freely and safely perform your relevant outdoor activities! Such headlamps are also used by the miners and surgeons so that their hands remain free to accomplish the relevant significant tasks! It is important to learn the working of such a significant device and therefore, straightway, let’s jump into the action!
A typical headlamp’s power source is the battery, either the disposable ones or the recharge ones, that illuminate the light source attached to it. That is when the switch is pushed to the ON position, the contact is established that enables the power flow from the power source supplied aka the batteries to the light source thus, illuminating them perfectly! When the switch is brought to the OFF position, the established contact is interrupted that results in the interruption of the beam.
This entire mechanism neatly arranged in a case is connected to a strap that can be worn around your head comfortably. Remember, this is only a typical working mechanism, which means there are various other headlamp types with specialized working mechanism available in the market.
For example, in a wind-up headlamp, instead of the battery, the mechanical winding up motion provides the necessary energy that can be used to illuminate the bulb attached, where the addition of capacitor can store the energy produced for a relatively longer duration thus, allowing the bulb to illuminate uninterruptedly for the allowable duration!
Like said above, the headlamps are a type of flashlight, particularly, designed to offer a hands-free working situation and therefore, can prove more useful than the typical flashlights during the relevant scenarios!
