ADVANTAGES OF LED
DURABILITY - The LED diode has a half life between 50,000 and 100,000 hours against the longest lamp, which does not reach 10,000 hours, or 1,500 hours of a halogen lamp.
ENERGY SAVING - The utilization of the Led's energy is approximately 90%, against 15% of the conventional lamp in the best conditions.
NULL MAINTENANCE - The Led works directly with the electric current, does not need auxiliary elements for its operation; said elements that have to be replaced over time, have a very low half-life.
COLOR - Thanks to LED technology, in an RGB diode we have 16 million possible color combinations, something unthinkable in conventional lighting.
ELECTRONIC TECHNOLOGY - The LED technology is totally electronic, with lower losses and better energy use, more performance, with less energy.
DO NOT EMIT UV OR IR - The LED only emits the frequency that we need, not causing disturbances or light pollution.
NON-CONTAMINATING RECYCLING - Due to the LED construction materials, we do not have the big problem of heavy metal gases.
LIGHT CONTROL - We can control and dimmer (attenuate) the light, in a range of 0 to 100%, something unthinkable in conventional light.
LOW VOLTAGE FEEDING - Avoiding many problems and dangers. Savings in electrical equipment By having a negligible consumption, we have considerable savings in protection and driving systems (cables).
PRESERVATION OF THE ENVIRONMENT - This is one of the most important points, since it requires less energy to work satisfactorily, we emit an amount of CO2 into the atmosphere, noticeably less and we also do not produce any kind of light pollution, as it is easily controllable.
WHAT IS AN LED?
LEDs are solid-state semiconductor devices which make them robust, reliable, long-lasting and vibration-proof, which can convert electrical energy directly into light. The inside of an LED is a small semiconductor encapsulated in an epoxy resin enclosure.
In contrast to other systems, LEDs do not have filaments or other mechanical parts subject to breakage or failures due to "melting", there is no point at which they cease to function, but their degradation is gradual throughout their life.
It is considered that at approximately 50,000 hours, when its flow falls below 70% of the initial, that means approximately 6 years in an application of 24 hours a day, 365 days a year.
This allows a huge reduction in maintenance costs since there is no need to replace them, so the cost of lighting is much lower.
Also, by its nature the ignition occurs instantaneously at 100% of its intensity without flicker or start-up periods, and regardless of the temperature. Unlike other systems it is not degraded by the number of ignitions.
The control of LEDs is another important factor. Given their nature they are easily controllable, being able to produce effects and allowing energy controls that with other devices is more difficult and expensive to obtain.
On the other hand LED devices are ecological because they do not contain mercury, have a longer duration, save a lot of energy, a significant point to be taken into account in the facilities and especially in the public type, and do not produce almost light pollution, another important aspect in public applications and especially traffic.
HISTORY OF LED
The first practical LED visible spectrum was developed in 1962, the development of LEDs has reached such a high level, that it has been chosen as the best alternative to the incandescent bulb, in neon light and fluorescent in many areas. It is predicted that with the already remote LED development, the current or conventional lighting sources will give way to LEDs in the near future. The future of the human being will be brighter because the common use of LEDs will mean savings in energy, costs and time.
Features and advantages of LED
The inherent features of LEDs define it to be the best alternative to conventional lighting sources, and provide a wider range of use.
An LED can be extremely small and provide a beam of high light performance.
Low electricity consumption
LEDs have a very low electricity consumption. Generally, an LED is designed to operate in the current 2-3.6V, 0.02-0.03A, this means that it does not need more than 0.1w to operate.
With operation at a nominal voltage, the current and the suitable environment the LEDs enjoy a long life approximately 100,000 hours.
High luminous efficacy and low heat emission
The LEDs can convert almost all the energy used in light, and therefore the performance of the mimes translates into a very high.
The energy classification of LED products depends on their performance Lm / W
Products with energy classification can be classified:
• +58 Lm / W .... class A
• + 80Lm / W ... Class A +
• +124 Lm / W ... Class A ++
