Can the bulb's true life reach 30000~50000 by LED?
LED life and quality, work current and many other factors. Life is calculated according to the half of the light
The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection. With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting. LED is far superior to traditional lighting products in light emitting principle, energy saving and environmental protection
According to the current LED manufacturing technology, LED bulb has a lifetime of up to 30000 hours.
