What is a flashlight made of? – Facts You Should Know About Flashlight

what is a flashlight made of

Rather than starting with the question "what is a flashlight made of ?", we would like to start by saying what a flashlight is.

A flashlight even known as a torch in some countries is a portable device used to emit light. The source of light is an incandescent bulb or LED which has taken over as the successor.

An image is on left side to show you the difference. The top picture shows the incandescent bulb flashlight and below is the LED flashlight.

They replaced the older source of light like the fire torches and candles. Previous flashlights had incandescent bulbs in them. This would give out a soft yellowish light, like any other household light bulbs. Here is a picture for your visualization.

The design resembles a tube like handle for the body. It is made up of brass, so it is a bit heavy to carry. Some are even made out of plastic. This handle is assembled to the head where the incandescent bulb is placed, in a pattern of like this image below.

These operate with the help of standard batteries. It may be an AA battery or an AAA, even a C size battery depending on its size. The size of the flashlight will also influence the amount of the light output. Larger flashlights are used for industrial purpose. A transparent cover is assembled at the top of the head; sometimes it is attached with the lens, to protect the bulb and to reflect the light source. A switch is placed on the handle of the flashlight for turning it on and off.

The Future

Our world is constantly changing with new innovative technologies. With all these changes around, a lot has changed for a typical flashlight. LED flashlights have taken over the traditional incandescent bulb flashlights. From the body material to the lens, there has been a significant change in today’s flashlight.

What are LED flashlights made of?

LED flashlights are commonly considered to be unbreakable, a life time lamp which does not need to be replaced. A LED flashlight is designed elegantly so even today’s generations use it without feeling any discomfort or embarrassment from using the brass body of a typical flashlight.

Body

LED flashlights have similar tube shape handle but with a slight change. The body is made out of an aluminum alloy, which in turn has made the body considerably lighter. The body is also available in variety of sizes for your use.

From size of a flashlight needed for your trekking adventure to a miniature size used as a keychain. A typical LED flashlight is about six inches. This tube houses other parts of the flashlight, including the batteries. Most of the manufacturers have even made a water proof body for the flashlight, with a range of around 100 meters.

Due the use of an aluminum alloy, the flashlights have a high resistant to damage caused by impacts. There is a special feature in some of the bodies like controlling the brightness of the light by simply rotating the head of the flashlight. But again this will defer from manufacturer to manufacturer.

Lens

Typically a transparent plastic cover was placed over the head in the traditional flashlight to protect the light bulb. The lens are improved in a LED flashlight, a tempered glass is placed replacing the previous cover. It is highly resistant and withstands impact so the LED bulb remains unharmed.

Bulbs

The traditional flashlights used incandescent bulbs but in today’s time we all prefer light-emitting diode commonly known as LED. The flashlights normally have a single LED bulb or cluster of 6 or more LEDs. It emits a white bluish light, as it has a higher Kelvin scale compared to an incandescent bulb.

Switch

The one thing which doesn’t change is the on and off switch. And we sure are happy about it. The LED flashlights still do have some other features along with the switch which differs from manufacturer to manufacturer. With its help the we can even flicker the light to attract attention when needed.

Batteries

With the invention of rechargeable batteries our lives sure has been welcoming. The LED flashlights use rechargeable batteries for the current to pass through the bulb for the output of light. Not all flashlight rely on batteries, well they do in a sort of way. Some flashlights have a non-removable battery that is charged through a USB port. It’s the same as charging your mobile phones. Like always we still provide you with a picture for your understanding. Like they say “seeing is believing.”

All these part together help to make a flashlight work, let it be the traditional or the new generation. Team work will make us glow in the dark.

The lighting facts end here people. We hope this article has helped you in understanding “what are flashlights made of?” Flashlights are useful in our lives and they change, so we will be there to write again about it.
