Most lighting designers believe that the quality of all LED products are the same. However, many LED Blue 150W manufacturers and suppliers, Asian manufacturers to low-cost global supply LEDs. Surprisingly, only a small part of these manufacturers to create high-quality LED. For applications that only used as a simple indicating the role of the low quality of the LED is sufficient to meet the requirements. However, in many areas of the requirements of consistency, reliability, solid-state instructions or lighting must be of high quality LEDs, especially in harsh environments, such as highways, military / aerospace, and industrial applications.
Safety requirements is very demanding, LED 200W must meet the high quality requirements of the fundamental factors in the environment of the New York subway station.
What are the factors that distinguish between the LED level of quality? How to tell the difference between the two LED's? In fact, the choice of high quality LED from the chip until assembly is complete, during which there are many factors to consider. Tier-OneLED manufacturing company to produce excellent and consistent indicators wafer start from the high-quality LED manufacturing materials, enough to make a good chip. Determine the conditions of the LED performance, the chemical materials used in wafer production process is a very important factor.
A 2-inch wafer can be cut out more than 6000 LED chip, there is only individual chip performance overall. A good chip manufacturer makes chips in the difference of color, brightness, and the voltage drop is very small. When the LED chip package is completed, many of their performance, there may exist a great difference, such as perspective. In addition, the impact of packaging materials is quite large, for example, silicone epoxy performance.
Classification ability
Excellent LED Blue 150W manufacturers can not only produce high quality chips, but also has the ability, depending on the LED color, brightness, voltage drop and perspective of its classification packaging. High quality LED suppliers to provide customers products with consistent operating characteristics, while lower-quality LED suppliers only provide LED similar to the "mixed".
For high-end, quality-demanding applications, such as the boundaries of the airport runway lights must meet the FAA-class color and brightness specifications, to ensure consistency of performance and security, LED packaging is strictly limited. Packing poor LED is used in demanding applications will lead to premature failure and other non-consistency problem is likely to lead to major accidents. Avoid the use of high-end and quality demanding applications in order to avoid equipment downtime, and ensure that the provisions in the design of the LED with reliable operating characteristics, "mixed" products is a very important。
