LED lamp - Wikipedia
An LED lamp or LED light [1] is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and fluorescent lamps.
Understanding LED Lightbulbs - Consumer Reports
2023年12月7日 · Today's LED lightbulbs can take your home's illumination to a higher level, but there is a learning curve. Here's how to make the most of these energy-saving bulbs.
What is LED? - Definition, Working, Properties, Uses, Advantages
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.
LEDs: What Are They? (Definition, Types, and Uses)
2021年3月12日 · LEDs are semiconductor devices, light is produced when the electrons combine with the material used as the semiconductor. LEDs can come in a variety of different shapes, colours and sizes. LEDs can produce the same amount of light around 90% more efficiently than older fluorescent or incandescent-style lights.
How LED Light Bulbs Work - HowStuffWorks
Let's begin with the basics: How does an LED produce light? An LED is what's called a "solid-state lighting" technology, or SSL. Basically, instead of emitting light from a vacuum (as in an incandescent bulb) or a gas (as in a CFL), an SSL emits light from a piece of solid matter.
Learn About LED Lighting - ENERGY STAR
LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light.
What Is an LED? - How-To Geek
2022年8月11日 · LED stands for "Light-Emitting Diode." The word "diode" is a key component here, because a diode is a semiconductor that only allows electricity to flow in one direction. To make an LED, manufacturers take two materials and place them in close proximity. The first material is typically a metal, such as aluminum or gold.
What Is an LED Light? The Anatomy of LED Bulbs - TCP Lighting
2017年8月16日 · What Are LED Light Bulbs? The LED abbreviation stands for Light Emitting Diode. An LED light bulb produces illumination through these diodes, as opposed to the filament and gas contained in incandescent and other older bulb types.
What Is an LED? - UMA Technology
LED bulbs can replace incandescent and fluorescent bulbs, providing energy-efficient and long-lasting lighting solutions. Displays: LEDs are used in displays, such as televisions, smartphones, and digital signage, due to their high brightness, contrast ratio, and color accuracy.
LED (Light Emitting Diode) | Light Bulb Types | Bulbs.com
LED light bulbs or lamps utilize light-emitting diodes in order to produce light. LED is a “solid-state” technology, which means that the materials used to generate the light are encased within a solid material.
