After evaluating all the prospects led U.S. company CREE has invested heavily in their production and is now a world leader in this field. Super bright and powerful CREE LEDs could replace incandescent bulbs in the majority of lighting fixtures in this lighting technology is constantly improving.
On the rights of the legislator of a fashion company CREE has created its own classification of LEDs by dividing them into two categories
In addition, it produces many types of lighting equipment and substrate material for high power LEDs the semiconductor crystals of silicon carbide.
Each of the two main groups is divided into subgroups with their own coding and features. As in mass production and introduced new development the number of subgroups increases.
So at the end of 2012, a led CREE XM L2 belonging to the group of high power LEDs. It is released on the platform of the latest generation of silicon carbide has increased on 20% brightness and luminous efficiency compared to the previous model XM L. the power and current consumption remained unchanged.
In other words, the company managed to create a more effective device while maintaining the level of energy consumption. This model is used to create directional lighting.
As says the manufacturer of high-brightness LEDs has been designed for high-quality full-color video screens and billboards to highlight architectural and decorative lighting. Their operating current is 30 to 50mA.
To date, high-brightness LEDs CREE has six subgroups. These include
Powerful model designed for CREE XLamp current exceeding 350 mA. They are widely used in all spheres of life, replacing incandescent and discharge lamps.
Models of high power LEDs quite a lot. They differ from each other in the brightness direction of the light flux efficiency and other characteristics. Despite the fact that CREE produces regularly updated types of LEDs, the old model do not remain forgotten as have their advantages.
For example, XR-E is more progressive and powerful CREE LEDs compared to the XR-C. They are designed for higher current and have the best light and color characteristics. But they do not model the red-yellow glow besides the cost of more of them with the same intensity of radiation. It turns out that under certain conditions it is profitable to buy early model than chasing new trends.
Before you mount the led chips on the Board or in case of their beyrout. This concept means only sort by the main parameters of the chip brightness, color temperature and color patterns along the length
