Light-emitting diodes have graduated well beyond their initial roles as panel indicator lights. Now LEDs are used for applications such as flashlights, automobile headlights and architectural lighting. Although LEDs are readily available, they're not very ...

LED stands for light-emitting diode and is a still-developing technology that may some day completely replace the incandescent bulb for lighting purposes. LEDs are commonly used in traffic lights and Christmas lights because of their long lifespan and low electricity requirements. LED bulbs...

Disco lighting may have gotten its commercial club start during the disco era of the 1970s, but the "disco" effect of a light hitting a mirrored ball can be identified as early as 1943, in the movie "Casablanca." Today, club owners and DJs are still trying to c...

How to Make a LED Into a Laser Pointer

A light-emitting diode (LED) and a semiconductor laser both generate light in the interface region between two different types of semiconductor materials. The energy of the light for both LEDs and lasers is...

An LED bulb in a flashlight is superior to that of an incandescent light because it uses less power from the batteries while providing a bright beam of light. The LED bulb is also more durable, but is not invulnerable. A broke...

Growing plants and shrubs indoors can be difficult without the right lighting setup. LED grow lights help you keep indoor plants alive. If your LED lights are too bright, they will burn your plants. If they are too dim, the plant will not get enough light and w...

LEDs are light-emitting diodes. They are specifically created to emit light, whether visible, infrared or near infrared. LEDs are polarized, which means that the way they are placed inside circuits is important. They are categorized by factors such as ...

LED lights, or light emitting diodes, can be used to kill bacteria. Many studies have been done proving the effectiveness of LED lights to kill bacteria and treat acne, mouth sores from chemotherapy and diabetic wounds. The light from LEDs benefit those wit...

Light-Emitting Diode (LED) bulbs are a relatively new technology in the lighting industry. They are considered a green technology, and require much less energy than traditional types of bulbs. One of the main criticisms of these bulbs to this point has been thei...

The performance of a well-trained technician can be appreciated by his clients. When his clients call upon him, he is expected to thoroughly fix their problem. Educating a technician on how to install LED lights may be a challenge at first, b...
