What Are the Advantages of LED Lights?

 

LEDs, or Light Emitting Diodes, are the light source in solar powered products. In order to understand what advantages the LED offers over incandescent lights, we must  lifetime of led light

first understand how the LED works. A light emitting diode is composed of a semiconductor diode. A semiconductor is a material that can conduct electricity. A semiconductor diode is composed of a semiconductive crystal that has added impurities in order to create a positive and negative side; since current flows in one direction through the diode. A region is then created in between the positive and negative zones, called a PN junction, which is where the action takes place within the diode; in our case it emits light.

Incandescent lights, on the other hand, operate on a different principle. Current is sent through a filament. The filament resists the flow of electrons through it, which causes the filament to generate heat. The radiated heat produces a visible light.

So what then are the advantages?

– Efficiency: An incandescent light requires much more energy to properly heat the filament in order to generate light. The light produced by an LED is a cool light. More light is produced per watt in an LED than an incandescent. Even more energy can be saved if the light is solar powered.

– Color: LEDs do not require filters, like colored bulbs, in order to create a specific colored light. Color is produced based on the material of the semiconductor.

– Size: LEDs come in many different sizes since they are not constrained to creating a vacuum in which to house the filament. LEDs can be smaller than 2 mm.
