Why should we use LED

Written by Administrator on .

A

Small Size

An LED is essentially a microscopic chip once encapsulated in an epoxy resin are extremely small and lightweight.

B

Low power consumption

LED consume very little power, far less than standard light bulbs leading to greatly reduced energy costs and extremely enhanced global energy savings. LEDs also require far less energy to manufacture than other light sources, reducing the environmental impact of artificial lighting even further. Generally a LED is designed to operate at 2 – 3.6V, 0.02-0.03A current which means a LED typically requires no more than 0.1W to operate.

C

Rugged

LEDs are rugged, solid state devices and are not susceptible to vibration such as with incandescent filament based bulbs.

D

Long Lifetime

When operating at specified voltage, current, and within specified environmental conditions, LEDs can enjoy a long life of up to 100,000 hours.

E

High Luminous Efficiency and Low Heat Emitting

Due to the special materials that are used to manufacture LEDs during electrons transition, LED’s mainly emit electromagnetic energy in the visible parts of spectrum. This is unlike incandescent filaments which are heated and emit large amounts of electromagnetic energy in the infrared spectrum which can’t be seen and is felt as heat. That is to say, LEDs can convert significantly more of the energy applied into light, and therefore LEDs have a higher luminous efficiency with substantially lower amounts of heat produced.

F

Environmental Protection

LEDs are made from non-toxic materials, unlike fluorescent lights that contain mercury which poses a danger to the environment and human health. LEDs are recyclable.

G

Unbreakable

The LED semi-conductor chip is completely embedded in an epoxy resin enclosure which is much more sturdy than traditional glass bulbs and fluorescent tubes. They are solid-state technology thus no loose and moving parts which makes LEDs virtually indestructible.

 

 

 

 

 

 

 

 

 

 

 

Answer:

The LED products consumed less power than the others.

You can use 3w LED bulb replacing the 8w Compact Fluorescent Lamps

You can use 3w LED bulb replacing the 30w incandescent lamp.

(You can search the “Luminous efficacy” get the data.)

Compare with Compact Fluorescent Lamps, LED just consume half of the electric power, which means, normally If you consume $1000 for lighting. With LED products at the same lighting condition, you only pay $500.
