LED, Lights Save Energy


The light is so useful when night comes. The atmosphere felt intimidating if you do not have lights shining. But to make the night feel alive, is also required electric energy is not small. In fact, thousands of dollars to the burden that must be paid by each citizen to pay a monthly electricity account.

To increase its charges, it is necessary to choose energy efficient lighting. One is LED (light emitting diode). The lamp is a semiconductor that change electrical energy into light. LED device is a hard and dense (solid-state component), so superior in terms of resilience.


LED with different fluorescent and incandescent lamps. Fluorescent lamp or incandescent lamp using filamen thin glass globe in the empty air. Electric current flows and heat filamen. At very high temperatures, glowing light on the filamen. When bolam oxygen leak and the filamen heat, the chemical reaction will occur so that the lamp is broken and can not be used again.

While Fluorescent or neon lamp requires mercury vapor to produce ultraviolet rays (UV light). Sinar is absorbed phosphorus that coat the inside of glass so the light will turn. Heat generated slightly more than the bulb, but still have the energy lost when processing ultraviolet rays into light kasat eyes.

Incandescent and fluorescent lights not in use after its bolam broken, but not so with the LED. The lamp is a type of solid-state lighting (SSL) and use the solid as a source of lighting is not so easily be damaged if the drop or bolam its broken. Placed with a collection of LED distance meeting to make the light brighter. One lamp can survive more than 30 thousand hours, and even reach 100 thousand hours.

LED only has a 4 color kasat eye, ie red, yellow, green, and blue. Rays to produce perfect white, the color of the light spectrum are combined. The most common color is merging red, yellow, green.

This lamp comes from the semiconductor material, not manufactured out of carbon material. When the LED is used throughout the world, the total electric energy for lighting can be reduced to 50%. Offset carbon emissions generated world could reach 300 million tons per day.
