The advantages of LED lamps

Led Lighting


Unequalled service life


The lifespan of LED lamps is much higher than that of other technologies: up to 100,000 hours (in the laboratory), 40,000 hours on the market (i.e. several decades of use) against 1,000 hours for incandescent lamps, 2,000 hours for halogen lamps and 10,000 hours for compact fluorescent lamps. Thus, the purchase and replacement of an LED lamp are less frequent, which improves the profitability of the investment.


Good energy efficiency with significant growth potential


If an isolated LED displays a very good energy efficiency (about 150 lm / W and up to 220 lm / W for the most efficient), an LED lamp offers a yield between 40 and 80 lumens per watt. This drop in efficiency is particularly related to the heat produced by the diodes contiguous in the lamp.
Thus, LED lamps currently on the market generally have a significantly higher energy efficiency than conventional lamps: 70 lumen / W for compact fluorescents and only 16 lumen / W for incandescent lamps.

Fortunately, the majority of lamps for home lighting now offer satisfactory lighting quality: an LED lamp of more than 800 lumens (equivalent to a 60W incandescent lamp) consumes between 9 and 12 watts only a 400 lumen LED consumes about 6 watts.

In addition, technological developments should improve the efficiency of LED lamps for the general public by bringing it around 100 lm / W. "Superbright" LEDs can already achieve an energy efficiency of up to 300 lm / W in the laboratory! Which means that eventually, we will have lamps that consume less than 4 watts and that light up like a 75-watt incandescent lamp.

Instant maximum illumination


LED bulbs reach a maximum brightness level upon ignition. Indeed, LED sources to admit frequent switching on and off cycles. They emit instantaneously the desired luminous flux, without revving, which may be advantageous for specific applications such as passageways.

Compact lamps


The compactness of the LEDs makes them very interesting for replacing recessed sources in false ceilings such as halogen spots or downlights.

The LED modules, directly installed in a luminaire and which can integrate a control electronics, facilitate the implementation of lighting management solutions such as presence detection or dimming according to daylight.

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...

LED lamps: definition

Image
LED lamps: definition 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 y...

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...
