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)
2025年1月1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.
The Ultimate LED Lighting Basics: Everything You Need to Know.
2023年9月16日 · LED lights are semiconductors that convert electrical energy directly into light, making them significantly more energy-efficient than traditional incandescent bulbs. Their lifespan is defined by lumen depreciation rather than burnout, and they slowly dim …
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 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? - How-To Geek
2022年8月11日 · You can't go anywhere these days without hearing about LEDs, whether in TV sets, light bulbs, smartphones, or otherwise. But what are they, and how are they different from other light sources? We'll explain. A Diode That Emits Light LED stands for "Light-Emitting Diode."
How Do LED Light Bulbs Work: A Complete Guide
2024年2月24日 · LED, or Light Emitting Diode, bulbs operate by converting electrical energy into light through the movement of electrons in a semiconductor material. Unlike incandescent bulbs that rely on heating a filament to produce light, LEDs generate minimal heat, making them highly energy-efficient and durable.
