subject: Led Light Bulbs - The Latest Concept In Providing Light To Spaces [print this page] LED lighting unit are just a collection of individual LED light bulbs. These bulbs work on the principle of a pin junction where the energy makes its way in one path from p to n side when a voltage is applied it. The p and n sides of the junction are made of different semiconductor components. Just by shifting the semiconductor material, the color of the imparted light can be totally changed.
A couple of years back LED light bulbs had confined usage. They were used only in digital devices and traffic signals, but now they are being used massively in non commercial and commercial enterprise lighting. Some LEDs produce light of wavelengths within 400 nm and 700 nm while infrared LEDs deliver light of the wavelength greater than 830 nm. With the launching of diodes that produce white light, the uses of these bulbs have become widespread.
Many people are utilizing LED lamps because of their extra benefits. They are energy efficient, environment friendly, and have good life expectancy. Also, they are tough and do not get easily shattered due to shocks. A LED lamp uses up one-tenth of energy consumed by an incandescent bulb and also has an average life span of 10 years. The luminous effectiveness of LED light lamps varies from 20 lumens per Watt to 55 lumens per Watt. Although the Compact Fluorescent bulbs also provide good luminous efficiency, most people do not prefer them as they contain dangerous mercury. Mercury poses problems both to the environment as well as to the health and well being of the residents.
Presently, there are no such difficulties with LED lamps. They are completely free from harmful materials. Moreover, they need to be replaced only once in a decade, hence the harmful toxins generated by them is very far less. Therefore, they are environment friendly. LED light bulbs are of many various types. If you need a focused light in one route, then LED floodlights and LED downlights are perfectly useful. LED globes are useful if you need diffused light that illuminates the entire area equally. One can also purchase LED tube lights, dimmers, and patio lights for their homes or office buildings.
Methods to Invest in a Light Emitting Diode Bulb :
Since LED light bulbs are actually expensive than Compact Fluorescent Bulbs and they last for almost a decade, you should choose them systematically.
Find out Your Needs - This includes wattage of the bulb, type of illumination necessary, and place for which it is required. You will get anything from 3v to 18v LED bulbs. A 3v LED bulb will be as good as 25W incandescent bulb, a 12v LED bulb serves the purpose of a 50W incandescent bulb, and a 18v LED bulb can be employed at sites where 100W incandescent bulb is essential.
The lighting effects of these bulbs differs variably upon their manufacturer and construction. While some 12v LED light bulbs functions as 40W incandescent bulb, some serve the purpose of 60W incandescent bulbs. Therefore, you have to check the entire requirements of the bulb prior to you buying the LED lamps.
Luminous efficiency is an aspect that can transform the functionality of the bulb. Even though most manufacturers give bulbs of 20 lumens per Watt performance but buying the one bearing efficiency between 40 lumens per Watt to 55 lumens per Watt is superior.
You should try to find the color of light you need. It depends on your taste and the area that has to be highlighted. Color is often represented by temperature in Kelvin. A meager temperature of 2100 K stands for warm colors like yellow, while high temperature of 5100 K usually means cold colors like blue. Most people prefer warm colors for household and cold colors for outside the house.
Beam angle is the other factor that should be taken into consideration while buying a LED light bulb. If you would like to focus light on a small place then a LED bulb with narrow beam angle of 15 to 30 degrees is perfect. If you want to lighten up a broad area with simple lighting, then decide a LED bulb with a wide beam angle of greater than 45 degrees as it widely spreads the light over a large area. Buying LED light bulbs is not difficult. Several online stores sell these lights. Before buying, spend some time researching on the types of LED lamps available. Also investigate their rates. Most providers offer warranty on these bulbs and you should find out it before striking the final deal. You should purchase the one having at least one-year approved warranty.
