Incandescent lights produce light with a glowing filament heated by electric current.See also: Light-emitting diode § History Illustration of Haitz's law, showing improvement in light output per LED over time, with a logarithmic scale on the vertical axisīefore the introduction of LED lamps, three types of lamps were used for the bulk of general (white) lighting: The text on retail LED lamp packaging may show the light output in lumens, the power consumption in watts, the color temperature in kelvins or a color description such as "warm white", "cool white" or "daylight", the operating temperature range, whether the lamp is dimmer compatible, whether the lamp is suitable for humid/damp/wet conditions, and sometimes the equivalent wattage of an incandescent lamp delivering the same output in lumens. LED lamps may use multiple LED packages for improved light dispersal, heat dissipation, and overall cost. Some LED lamps are drop-in replacements for incandescent or fluorescent lamps. Light output decreases gradually over the lifetime of the LED. Frequent switching on and off does not reduce life expectancy as with fluorescent lighting. LEDs come to full brightness immediately with no warm-up delay. The LED lamp market is projected to grow from US$75.8 billion in 2020 and increasing to US$160 billion in 2026. Generally the current waveform contains some amount of distortion, depending on the luminaires' technology. The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps. LED lamps require an electronic LED circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses. Commercial LED lamps have a lifespan several times longer than both incandescent and fluorescent lamps. The most efficient commercially available LED lamps have efficiencies exceeding 200 lumens per watt (lm/W) and convert more than half the input power into light. LED lamps are significantly more energy-efficient than equivalent incandescent lamps and are significantly more energy-efficient than fluorescent lamps. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally bonded to the heat sinkĪn LED lamp or LED light is an electric light that produces light using light-emitting diodes (LEDs). The filaments are visible as the eight yellow vertical lines. Buy light online on our website today! Enjoy discounts when shop light on our website!
