What Are Lamps Led?

A lamps led is a light that uses an LED (light-emitting diode) and has been built into a lamp or light bulb. LED lamps use much less energy than incandescent and many types of fluorescent lamps, and they last a lot longer as well.

LEDs are used in a wide range of applications, from traffic signals and street lights to flashlights and Christmas ornaments. They’re also starting to replace the bulbs in three-way dimmer switches and more and more desk and table lamps. In fact, you’ll find them everywhere from digital clocks and car headlights to desk and table lamps. They use a fraction of the power of incandescent bulbs and don’t emit as much heat, so they run cooler and are more resistant to burns.

An LED emits light when it gets excited by an electric current. The light passes through a semiconductor, which is the “brain” of an LED. The semiconductor absorbs some of the electricity, which causes it to heat. This heat dissipates into the surroundings as infrared radiation and, if the LED is designed properly, some of it as visible light.

Most LEDs are made from red, green and blue emitters that combine to produce white light, but there are also devices that use only one color of LEDs to create a particular shade of light. LEDs are designed to be directional, so the light they emit is mainly directed in one direction. If you want a non-directional lamp, it’s necessary to add a diffuser or multiple individual LED emitters to distribute the light more evenly.

The circuit board in an LED lamp is often called a driver or an LED controller. It takes in energy from the socket and tells the LEDs what to do, like turning on and off or changing color. It also protects the LEDs from voltage or current fluctuations that could damage them. The circuit board will heat up when the LEDs are being used, but it won’t get nearly as hot as a halogen, incandescent or fluorescent lamp.

While LEDs have been around for years and are used in things like digital clocks, Christmas lights and flashlights, they didn’t really take off until manufacturers began making them in standard replacement-size light bulb form. When choosing an LED lamp, pay attention to its lumens rating. You’ll also want to consider the color temperature of the light. Lower color temperatures can give a room a warm, cozy feeling and are great for reading or working in the kitchen or bathroom. Higher color temperatures look more like natural light and can make a room feel energetic. The ENERGY STAR label on LED bulbs is another good place to start — ENERGY STAR bulbs must meet specific requirements designed to replicate the experience of using a traditional bulb. These are the best choice for most consumers, as they’re tested to ensure that they do just that. The ENERGY STAR website offers a searchable database to help you find the right lamps for your needs.
