LED stands for light emitting diode (light-emitting diode). Each time it delivers electrical current a rectifier diode glows, these diodes are what make up the LEDs. To build lights and all sorts of electronic products, the industry uses this technology. Over time the LED technology has undergone such technological innovation, which made possible its application in many fields, even more traditional.
Usually this technology is widely used for architectural lighting effect or a specialist. Also variants of most modern LEDs colours (colors such as green, red and blue), have made possible the use of this technology applied to exit signs and emergency, the headlights of cars and traffic lights. Hasn’t always been all fun and games though. The first attempts to apply LED lighting in traditional systems has failed miserably, primarily to a lack of colors and then because they were not efficient enough in the luminous flux or lumen per watt ratio was too low.
Fortunately, things have changed and the technological evolution of LEDs has allowed the industry to use the LEDs in a variety of applications. The first attempts to use LED technology in traditional lighting systems are miserably failed as it was still mostly old devices, which were not designed for this type of technology. But the improvements and benefits that brought this technology were so obvious, that prompted the lighting industry to the creation of completely new products able to exploit the potential of this technology.
A LED can be mounted on existing equipment, with appropriate adjustments, but the device has not been designed for the LED technology is unable to exploit the full potential of the LED. What differs more in the structure of the old equipment is the management of heat dissipation, which in traditional systems is completely different than the LED light. In addition to influencing the low efficiency of the LED on a traditional appliance is its design, which is not able to take full advantage of the lighting of LED technology.
The famous saving
Presenting many advantages, including a high durability LED lifespan and efficiency, the technology industry did not think twice before introducing LEDs everywhere. Maintenance that then require the LEDs is noticeably shorter than that required by traditional systems, this despite a much longer life cycle. This is translated with considerable savings and cost reductions, which the world has been trying for years to chase in every field, not just technology. How can then evaluate an LED product?
Often people think that LED to assess a good product, you have to take into account the lumen output, but this is not real and can be misleading. For a complete evaluation of the full efficiency of the product must evaluate the LED, optical control, heat management and heat loss. Also should know when the product will reach the natural decay of 30% of the lumen. Products with optimum thermal management and optical efficiency will produce on average more lumens of products such as traditional high-intensity discharge lamps.
