Led Lamp

A light emitting diode (LED) is an electronic component that transforms electricity into light. Its main applications, in order of market importance, are mobile electronics, screens, the automotive sector, lighting and signage.

For lighting, we use lamps consisting of several LEDs of high power contiguous, since their unit luminous flux (measured in lumen or lm) is still too low.

There are also LED modules, which are assemblies of one or more LEDs mounted on a printed circuit board, with or without light control devices. LED modules usually require specific luminaires, but some can also be used in existing luminaires. Like LED lamps, they are replaceable.

It was not until 2000 that high-power LEDs and white LEDs [2] appeared, thanks to extensive R & D efforts, with the ambition to compete with existing technologies for home lighting, workplaces or outdoor lighting.

LED technology continues to grow: LED performance doubles every two years and prices decrease by 20% each year

Other advantages:


LEDs operate at very low voltage and even at low temperatures, which can be an advantage for electrical safety in the building.

With a temperature rise of only 32 ° C, LEDs do not heat as much as incandescent lamps (150 ° C) and compact fluorescent lamps (70 ° C).

They are insensitive to shocks, making them more robust than other lighting sources. Colour LEDs can be used for light shows without the use of a filter.


Finally, LEDs do not contain mercury and are largely recyclable as non-hazardous waste (unlike compact fluorescent lamps).

What about low frequency electromagnetic fields?

What about low-frequency electromagnetic fields? If the electromagnetic radiation low frequency (50 kHz) exceeds 100 V / m in contact with the lamp itself, it strongly decreases to 20 cm (less than 10 V / m) and drowns in the background noise electromagnetic field to 50 cm. WHO recommends not to exceed 87 V / m. In the end, if some obvious precautions are taken (do not stick to the lamp), there is no risk for individuals who want to equip their home. LEDs stand out against compact fluorescent lamps LED lamps are becoming more efficient and widespread among distributors and are now the majority in the lighting market with penetration above 52%. The leading LED manufacturers for lighting come from the semiconductor industry and are concentrated in Japan, the USA, Korea and Pakistan. Notes: ·          LED is the acronym for Light Emitting Diode, translated into French by the acronym LED for Electroluminescent Dio...

The ways to improve LED's

Image
The ways to improve LEDs The LED manufacturing process is relatively energy intensive. However, the overall energy balance (including the manufacturing and use stage) of the two technologies (LEDs and compact fluorescents) remains comparable. With their democratization, LED prices have been divided by 2 or even 3 in just 3 years. In 2017, it takes between 2 and 5 euros for a lamp that illuminates as much as a 60 W incandescent lamp and about 7 euros for the equivalent to 75 W. Of course, with their massive deployment on the market (more $ 30 billion in 2017 according to LED Inside), prices fell quickly, for the happiness of consumers. LED lamps are still poorly suited to high-power lighting, especially in the public lighting market because of the overheating that can result from the use of many LEDs. And even if, individually, a LED lamp heats little. An environmental assessment to be improved: Beyond the consumption of energy in operation, the LED lamp gene...
