What’s LED Lightings?

1. What Does LED Stand For?

Light-Emitting Diode

A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows – characteristically in only one direction (in through the anode and out through the cathode). Diodes are generally made from semi-conductive materials such as silicon or selenium – substances that conduct electricity in some circumstances and not in others.

2. What is LED Lighting? 

A light-emitting diode is a semiconductor device that emits visible light when an electrical current passes through it. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.

3. Lifetime of LED Lighting Products

The lifespan of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.

4. How are LEDs Used in Lighting 

LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities. Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs. Other LED light fixtures may have LEDs built in as a permanent light source. LEDs offer a tremendous opportunity for innovation in lighting form and fit a wider applications than traditional lighting technologies.

5. Why Choose LED and advantages of LED

• LifeSpan :- One of the most significant advantage of LEDs when compared to traditional lighting solutions is their long lifespan. The average LED lasts 50,000 operating hours to 100,000 operating hours or more; This means they last 2-4 times as long as most fluorescent, metal halide, and even sodium vapor lights and up to 40 times as long as the average incandescent bulb. Having to replace your lights less often has two major advantages: lower maintenance costs and consumption of replacements parts.

• Environmentally Safe :– Traditional lights like fluorescent bulbs often contain harmful elements like mercury and thus require special handling for disposal at the end of the product’s useful lifespan. None of these considerations are necessary with LEDs which results in a more environmentally friendly product.

• Operate on Very Low Voltage :– In many cases, LEDs operate on very low voltages. This makes them suitable for many applications in both indoor and outdoor lighting applications where other lighting might not meet such requirements.

• Better Light distribution :- LED have better directional light distribution control it as emits light at a distribution angle of only 180 degrees compare to other lighting sources that emits light at 360 degrees around the source. The latter waste energy by emitting light in all direction; often illuminating areas which isn’t required (such as the ceiling). This drives up the costs for the system in general and inevitably results in losses. In contrast, fewer LED lights are required to achieve the same level of brightness given off by fluorescents and incandescent lights. Fewer lights will reduce energy consumption and will therefore present a benefit to the environment.
