What Is Bulb Lamp LED?

Bulb Lamp LED refers to any lightbulb that uses light-emitting diodes (LEDs) technology to produce visible light, often known as "solid-state lighting", since its operation does not rely on filaments or gases like those seen in incandescent, halogen, or fluorescent bulbs for illumination. LED bulbs tend to last significantly longer and offer greater durability compared with traditional bulbs.

LED lamps come in an assortment of shapes, sizes, and colors designed to complement fixtures that previously utilized traditional bulb designs. While some LEDs are made specifically as replacement bulbs for 40, 60, or 75W incandescent bulbs, others feature unique properties that make them better suited for specific applications or home decor styles. Overall, LEDs are more energy efficient than incandescent bulbs by producing the same amount of illumination while using significantly less power and lasting 10-50 times longer than traditional bulbs.

LED bulbs offer several distinct advantages over their more conventional counterparts, including their long lifespan and increased brightness for years before needing replacement - often as long as 50,000 hours! This reduces both energy usage and utility bills while simultaneously cutting back on light bulb purchases and disposal needs.

These bulbs are also more resilient than their counterparts, as they can better withstand shocks and vibrations, as well as operate at lower temperatures for safer handling by users. Furthermore, LED bulbs tend to be smaller in size - often making them ideal for use in ceiling fan light fixtures, pendants, table lamps, bathroom vanity lights, wall sconces, or chandeliers.

Most retail LED bulbs come packaged with labels that display information about the light they produce, such as its lumens per watt rating, operating voltage, color temperature in Kelvins or color name (such as warm white or cool white), dimmability compatibility, and more. Furthermore, certain models qualify as Energy Star compliant while meeting specific UL and testing requirements.

LED bulbs differ from their incandescent and halogen counterparts in that they use an electronic circuit board that converts AC current into DC voltage, powering LED chips instead of needing an active filament to produce light. A chip is composed of semiconductor materials such as gallium nitride or gallium arsenide that emit visible light when an electrical current flows through it. Electron movement and recombination within semiconductor material generate light, with its color determined by its chemical makeup. A bulb contains several additional parts. First is the heat sink - a piece of metal designed to dissipate heat produced by LED chips - as well as an optical lens to spread light more evenly throughout its surroundings. Heat sinks typically feature aluminum or copper construction to lower the risks of thermal burns when touching them directly.
