The high brightness that is currently obtained with the LEDs allows them to compete with other sources of light. The LEDs maintain over 70% of their original luminous flux for 50,000 hours, much longer than conventional lights.
What is an LED?
The light emitting diode, also known as LED , is a semiconductor device that emits incoherent light of reduced spectrum when the PN junction thereof is directly polarized and an electric current circulates through it. This phenomenon is a form of electroluminescence. The color depends on the semiconductor material used in the construction of the diode and can vary from the ultraviolet, through the visible, to the infrared.
Conventional lamps lose between 20% and 50% of the light generated due to the lack of addressing in the light source, loss that becomes light pollution in the environment. The LEDs overcome this problem by having a directional light source. Therefore, they do not pollute the space with unnecessary light. The light pollution is the one that at night in the cities does not allow to see the starry sky.
Unlike fluorescent lights, LEDs are more efficient in environments with low temperatures. LEDs have no ignition problems in cold environments and are one of the most reliable sources of light outdoors.
Unlike many other lighting technologies, LEDs do not contain mercury or heavy metals. Not only the LEDs are better for the environment during their operating period, but after that the LEDs will not damage the environment with polluting substances.
Another added benefit is that white LED light can reach a CRI of 80 on the color interpretation scale, compared to a score of 20 or less for sodium light.
This pure white LED light not only provides a better spectrum for the human eye, but also increases the amount of visual information captured by security cameras. Therefore, the LEDs in a parking lot or garage reduce the total cost of lighting in this area and potentially increase safety levels for all users. With the current LEDs, a luminous flux of 115 lumens per LED at 350mA is obtained, thanks to which, thanks to this luminous flux, it is possible to create road luminaires that replace the traditional ones.
Taking into account the longer life of the LEDs, the total cost for street lighting is considerably reduced, because in LED lighting it is not necessary to replace the bulbs every few years with the high costs that this causes.

LEDs for RGB
One of the most important and visible uses of LED lighting is lighting applications with RGB color change. The RGB LEDs are widely used today for its simplicity in design and easy installation in any type of lighting installation. They combine a great power of light with a low electrical consumption, and the high resistance of his materials do that the LEDs are the best option for applications of change of color RGB. Another reason for the popularity of LEDs is that they are economical in terms of euros per lumen. For most color changing installations, many lumens are needed. The lighting designer must pay attention to how to minimize the total cost of the installation of color change.
