Modern Light with LED Flashlights

Filed Under General | Leave a Comment

I had my first LED flashlight almost ten years ago. It was a small keychain using a button-cell battery. Since that time, LED flashlights have advanced a lot and new models have shinier lights using more LEDs.

Light-emitting diodes or LEDs are solid-state transistors which glow when electricity passes through them. However unlike incandescent bulbs, there are no filaments, and no bulbs. It doesn’t burn, nor produce much heat. And best of all, it eats up a small amount of power.

The small power usage makes the LED flashlight a very green proposition. It doesn’t require a large battery to produce light and it doesn’t generate lots of heat either. And since it’s a single piece, it has a long life span.

Although common LEDs come in all colors, the diodes used in flashlights tend to have a bluish tinge. This is not really a obstacle to having a luminous flashlight. In fact, there are now small projectors using LEDs for the lighting element.

The titanium LED torch are available in an array of sizes. There are the keychain models which are smaller than a finger, with larger units using banks of LEDs. Using arrays LEDs, the size of a lighting unit can be as large as any normal flashlight, with a wide range of designs. There was even one unit which make use a circular array of LEDs for a flashlight lamp complete with reflector unit, with a rectangular bank on the side but without the reflector unit. This could come in handy when camping, replacing portable battery powered fluorescent lamps.
