La nueva luz LED

Las bicicletas modernas ahora vienen equipadas con lámparas LED que se pueden dividir en tres tipos de modo de iluminación: LED único de alta potencia, LED múltiple y el LED múltiple de alta potencia, que es una combinación de la primera y la última. Dicho esto, las tres luces de bicicletas dan rayos de luz consistentes que seguramente anunciarán su presencia a todos en el camino.

Light-emitting diodes or LEDs are becoming popular as a technology in different appliances and gadgets. Today, we have smartphones and televisions with LED screens, as well as other devices that use it for signalling and displaying purposes.

In the context of our discussion, let’s take a LED para gasolinera look at one LED application that has an enormous potential, both in terms of efficiency and sustainability: lighting. Whereas conventional lighting (halogen and incandescent) use a mechanism that heats a tungsten filament to produce light, LEDs generate light by running an arc of electrical current between two electrodes. LED lights are also different from compact fluorescent lamps (CFL), which produce light by electrically exciting gases (think argon and mercury vapour) inside their spiralling tubes.

LED them go

How do these differences give LED an advantage? Why do we need to let other lighting types go and use LED technology instead?

While we should admit that LED lights do cost more upfront, the benefits outweigh this seeming disadvantage. You see, lighting that requires the filament-heating mechanism wastes so much energy to heat that only 10% is translated to light. There is a reason why incandescent lighting frequent incubators in poultry farms – they give out so much heat, much more than they give light! LEDs beat these types by utilising as much as 80% of the energy used for light. Also, LED lights, at their optimal capacity, can run for up to 80,000 hours without dimming. This is overwhelming compared to filament types that have a lifespan of up to 5,000 hours only.

So the first major benefit we see here is savings in the long-run. Electricity is used more efficiently, which helps save in utility expenses. Then, there’s the benefit of not replacing bulbs as frequently.

We turn now to LED’s advantages over CFLs. CFLs contain harmful mercury vapour, so that when bulbs are broken, they tend to emit this poisonous gas and expose whoever gets to inhale it to health hazards. This mercury component is also responsible for CFLs’ disposal problem. On the other, LED lights usually don’t incorporate this kind of harmful gases in its mechanism. Thus, the second major benefit of LEDs is their tendency to be produced without environmentally harmful materials.
