Science has millions of advantage but it also has same number of disadvantage too. It has provided humankind every possible thing that can make their life easy, but on the other side, it has affected our environment very badly. However, it can be assured for theses affect to be as less as possible through some ways. One simple thing that we can do is to replace standard light bulb in our home with LED energy saving light.
LED lights were discovered in Russia in the mid of 1920 but there commercial use was found in 1962 and at that time these lights were introduced as commercially feasible electron component. Gallium arsenide was the component through which these lights were made at the early stage and this light produced a red and infrared light with low intensity. Some other substance has been added to the gallium now, which allows the light length to be shorter and changeable colors. These lights are more beneficial and human friendly than the standard bulbs. Some of these benefits are described below.
For standard lighting bulbs lot of toxic substance has been used, and these substances are very dangerous and can harm the environment in very bad way but led lights has been made through non-toxic substance are environment friendly.
In standard bulbs, only 20 % of energy transforms into lighting, 80 % of energy transforms into light, On the other hand LED light convert 80 % of energy into lighting, and only 20 % create heat. These lights have been considered most energy efficient until now.
These lights are longer lasting than the standard bulbs because production of heat in those bulbs is very less and does not let the bulb get extra heated that prevent it from burning.
Because of solid components and absence of filament that is very sensitive, these bulbs are sturdy and these components also make them oppose the tough situation like shock, vibration, wind and rain and for the same reason, they are best for outdoors. It has little risk of burning and breaking.
UV radiations are harmful for human beings. They can cause skin diseases and damage the eyes. So the LED lights are build in a way that the emission of UV is very low and also produce less infrared light. Therefore, these lights are suitable for UV and infrared sensitive material.
These led lights function with very low voltage that can save electricity and can be handled easily during installation. As soon as the switch is on, they will start brightening so there will be no waste of energy. Slandered bulb takes several second to brighten up after fading and flickering lot of time.
