Green Energy
Full abbreviation of LED is Light Emitting Diode. LED is a semiconductor device which provides visible light when an electric current is passed through them. LED is a kind of Solid State Lighting (SSL) like Organic Light Emitting Diode (OLED) and Light Emitting Polymer (LEP). After getting an electrical current, the diode emits a bright light around the small bulb. Basically, diodes are used in many technologies like radios, televisions and computers as an electrical component for conduction.
Generally, LED includes common colors like red, green and blue. Characteristically LED is not white light sources. Instead, LED emits closely monochromatic light which makes them highly efficient for colored light applications such as traffic lights and exit signs.
In order to provide white lighting to our homes and offices, LED of various colors are mixed with a phosphor material which converts the color of the light. Phosphor is a yellow material which you can see on some LED products. Now, LED lights are integrated with bulbs and fixtures for general lighting applications.

What is LED?
Generally, LED includes common colors like red, green and blue. Characteristically LED is not white light sources. Instead, LED emits closely monochromatic light which makes them highly efficient for colored light applications such as traffic lights and exit signs.
In order to provide white lighting to our homes and offices, LED of various colors are mixed with a phosphor material which converts the color of the light. Phosphor is a yellow material which you can see on some LED products. Now, LED lights are integrated with bulbs and fixtures for general lighting applications.
How does LED work?
Basically, a diode is a semiconductor device which allows current to flow only in one direction. When a diode is connected to an electric current carrying conductor, it excites electrons within the diode and prepares them to release photons which create light.One of the significant features of LED is that it can emit light in a specific direction. Color of the light is a direct result of the energy gap in the semiconductor of the diode. This indicates that LED can easily produce bright spectrum of colors consuming very small amount of power. LED is very sensitive in thermal and electrical conditions. So, it must be carefully integrated into lighting fixtures.
Shapes of LED Lights
LED Lights have five basic shapes. They are as follows:
- Flood Lights: These lights are ideal for landscape lighting, outdoor floodlighting and motion sensor.
- Spot Lights: These lights are Good for track lighting and overhead recessed lighting.
- Globe Lights: These lights are used in living room and bathroom vanities.
- Decorative bulbs: These bulbs are widely used in wall sconces and decorative fixtures.
- A-line bulbs: These bulbs are effective for room area lighting, hallways and reading lamps.
Advantages of LED Lights
LED lights have various types of advantages over other light sources:
- It's efficiency is very high.
- It has high levels of brightness and strength.
- It consumes very small amount of power.
- It can resist vibration and shock. So, it is highly reliable.
- Radiated heat is very low.
- No Ultra Violet (UV) rays.
- It can be programmed and regulated very easily.
- It has exceptionally long lifespan.
- It is a cost effective and environmentally friendly technology. Because, it saves energy and decreases carbon emissions.
