Over the last 5 years, LED lights have revolutionized the Indian lighting industry. However, being a relatively new technological entrant, people are still not very clear about the various terminologies and features associated with LED lights. Here, we try to address a few of the frequent queries. In case you have further question, feel free to mail us. We will reciprocate at the earliest.
Light-emitting diodes (LEDs) are solid-state lighting components. Each LED consists of a semiconductor diode that emits light when a voltage is applied to it. They have no moving, fragile parts and can last for decades. LEDs can be many times more energy-efficient than light bulbs, depending on the application. LED lighting can save up to 85 percent of the electricity used by incandescent bulbs and up to 50 percent of electricity used by fluorescents.
The electronics industry has used LED technology for several decades as indicator lights for various electronic devices. In more recent years, LED technology has progressed to the point where it is viable for general lighting applications.
Most of the energy emitted from incandescent bulbs is converted to heat instead of light. That’s why you’ll burn yourself if you try to touch an incandescent bulb once it’s turned on. Since LEDs consume significantly less energy, they don’t emit as much heat. That’s why you typically won’t burn yourself if you try to touch an LED light once it’s turned on. LED lights are also designed to last about 50 times longer, which means less ladder-climbing maintenance and less waste.
The most prominent reasons for people to switch to LED are:
High efficiency: Roughly 80% of the energy used in an incandescent bulb is wasted via heat. 80-90% of energy used in LED lights is used in the generation of light. The term used to describe LEDs minimal heat generation is ‘cold lighting’.
Less Maintenance: LED lights have a significantly higher lifetime. This can range from around 20,000-100,000 hours per luminaire. The costs associated of replacing conventional lamps over 20 times during the lifetime of an LED are quite staggering, especially if maintenance costs are high to start with.
Environmentally Friendly: LEDs do not contain any harmful chemicals or heavy metals. Compact Fluorescent lights contain mercury which is highly toxic. Both incandescent and CFL lights emit a small amount of UV radiation whereas LEDs emit none.
Lesser CO2 Emissions: A large percentage of energy comes from the burning of fossil fuels. This in turn releases greenhouse gases into the atmosphere. Less energy needed to facilitate the use of lights means a decrease in the amount of fossil fuels being burnt. Using LED lights will contribute greatly in reducing your carbon footprint.
No. Unlike incandescent and fluorescent lighting which will fail sooner when switched on and off more often, LED lighting is unaffected by how often it is switched on and off.
