LEDlampide

LEDlampide are lighting devices that use light-emitting diodes as the primary light source. They are designed to replace traditional incandescent or fluorescent lamps and are commonly used in homes, offices, and public spaces. LEDlampide convert electrical energy into light with high efficiency and long life, and they are available in a wide range of shapes, sizes, and color temperatures.

Technically, a LEDlamp consists of a LED array mounted on a heat sink, an electrical driver to convert mains voltage to the appropriate DC current, and a lens or diffuser to shape the light. White light is typically produced by blue LEDs with phosphor coating. The brightness is described by luminosity (lumens) per watt, with modern lamps often achieving tens to over a hundred lumens per watt, depending on design. Color temperature ranges from warm to cool white, and the color rendering index (CRI) indicates how faithfully colors are shown.

Performance and life: LEDlampide offer long operating lifetimes, often tens of thousands of hours, low heat emission at the illuminated surface, and instant full brightness. They are directional by design, which can improve efficiency in many applications but may require diffusers to reduce glare.

Applications and benefits: The main advantages include reduced energy consumption, lower maintenance costs due to longer lifetimes, and flexibility for integration with dimmers and smart lighting systems. They are widely used in residential, commercial, industrial and street lighting.

Safety, standards and environment: LED lamp products are subject to electrical safety, RoHS/REACH and other regulatory requirements. Proper disposal and recycling of LED lamps is encouraged to minimize environmental impact. Some concerns exist about blue light and glare, making appropriate CCT and shielding important.

History and market: LEDlamps gained market traction in the 2010s as technology matured, contributing to the phase-out of many incandescent lamps worldwide.
