Lighting – LED Technology
1. What is it
LED light bulb refers a solid-state lamp that uses light-emitting diodes as the sources of light. LED light bulb produces light when electrons move around within its semiconductor structure. It has a longer service life and high higher energy efficiency than other source of lighting such as fluorescent and incandescent light bulb though its initial cost is much higher.
LED light bulb has wide range of applications including both general and specific.
The following are some of the applications on LED technology
Indicators and Signs – traffic lights, exit signs, brake light for cars
Lighting – LED light bulbs, LED street lamps, LED backlit for TV and laptops
Smart lighting – transmission of broadband data, wireless transmitters for data transport
Sustainable lighting for architecture
Optical fiber and free space optics communications – remote controls, sensors
2. Why was it disruptive at the time it came to market
As a matter of fact, the invention of LED technology does not bring much surprise to the society. As the main purpose of LED is a substitute for the incandescent light bulbs, even without this invention, it won’t cause any major inconvenience to our lives. The major benefit of the invention is its impact on environment. For example, it improves the energy efficiency of light bulbs; lengthen the usage life of light bulb by 30-50 times than an incandescent light bulbs etc.
3. How society adapting to changes inspired by LED technology
With the ample benefits of LED lighting comparing to traditional lighting such as incandescent light bulb, the world is gradually moving towards the era of LED and the importance of incandescent light bulb is gradually fading out. A report estimated that by the end of 2020, people wouldn’t be able to find any incandescent light bulb in the market because they are all replaced by LED or LED related products.
In fact, governments as well as companies have put a
