What are LEDs

LED stands for light emitting diode. LED lighting products produce light approximately 90% more efficiently than Incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.

Lifetime of LED

The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly overtime. Unlike incandescent bulbs, LED  “lifetime”  is established on a prediction of when the light output decreases by 30 percent.

Advantage of LED lighting

Long service life

it is one of the greatest benefits of LED lights. LEDs used in this type of lighting have a high work efficiency and thus may run for up to 11 years compared to energy saving lamps with a service life less than a year. For example, LEDs operating 8 hours per day will last for about 20 years of service life, and only after this period will you be forced to replace the light source for a new one. In addition, frequent switching on and off has no negative impact on the service life as in the older type of lighting.

Efficiency

LEDs are currently the most energy-efficient source with less energy consumption (electricity) than incandescent, fluorescent, meta halide or mercury lamps, within the luminous efficiency of 80-90% for traditional lighting, this means that 80% of the energy supplied to the device is converted to light, while 20% is lost and converted into heat. The efficiency of the incandescent lamp is at 5-10% level – only that quantity of supplied energy is converted to light.

Resistance to impact and temperature

in contrast to traditional lighting, the LED lighting advantage is that it does not contain any filaments or glass elements, which are very sensitive to blows and bumps. Usually, in the construction of high quality LED lighting, high-quality plastics and aluminum parts are used, which makes LEDs more durable and resistant to low temperatures and vibrations.

Heat transfer

LEDs, compared to traditional lighting, generate small amounts of heat due to their high performance. This energy production is mostly processed and converted into light (90%), which allows direct human contact with the source of LED lighting without the exposure to burn even after a long time of use. In addition, exposure to fire is limited with LEDs in contrast to old light types that would heat up to several hundred degrees. For this reason, LED illumination is more favorable for the goods or equipment that are extremely sensitive to temperature.

Ecology

the advantage of LED lighting is that LEDs do not contain toxic materials, such as mercury and other metals, that are dangerous for the environment, in contrast to energy-saving lamps, and are 100% recyclable which helps reduce carbon dioxide emissions. They contain chemical compounds responsible for the color of its light (phosphor) which are not harmful to the environment.

Color

In LED technology, we are able to obtain each illumination light color. Basic colors are white, red, green and blue, but with today’s technology, progress is so advanced that we can get any color. Every individual LED RGB system has three sections, each of which gives a different color from the RGB palette color – red, green, blue.

LED vs Incandescent

Incandescent Watts Lumens LED Equivalent
40W 450 lm 5-10W
60W 800 lm 5-10W
75W 1100 lm 14W
100W 1600 lm 16-20W
150W 2600 lm 25-28W

Did you know that watts don’t tell you how bright a light will be ?

LED lighting differs from incandescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. Incandescent bulbs produce light using electricity to heat a metal filament until it becomes “white” hot or is said to incandescence. As a result, incandescent bulbs release 90% of their energy as heat. LED lighting differs from incandescent in several ways.
