Most lighting designers believe that the quality of all the LED products are the same. Only a small part of the manufactures to produce 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.
In the New York subway stations and other environmental, safety requirements are very demanding, the led light energy savings must meet the high quality requirements of the fundamental factors.
Distinguish between the level of LED quality factors? How to tell the difference between the two LED Lights’s? In fact, high-quality LED chip start until assembly is complete, during which there are many factors to consider. Tier-One LED manufacturing company produce excellent and consistent indicators wafer starting from the high-quality led light energy savings 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 light energy savings 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. After completion of the LED chip package, many of their performance have big difference, such as perspective. In addition, the impact of packaging materials is quite large. For example, silicone has better performance than epoxy resin.
Classification ability
Excellent LED manufactures can not only create high-quality chips, but also has the ability to classify the color, brightness, voltage. High quality LED CHINA suppliers can only provide customers with consistent operating characteristics, while lower-quality LED suppliers only provide LED which is similar to the “mixed”.
For high-end, quality-demanding applications, such as the boundaries of the airport runway lights must meet the FAA-calls color and brightness specifications, to ensure consistency of performance and security, led light energy savings packaging is strictly limited. Packing poor LED is used in demanding applications which will lead to premature failure and other non-consistency problem which is likely to lead to major accidents. In order to avoid equipment shutdown and to ensure that the operating characteristics specified in the design of the LED reliable, high-end and quality demanding applications should avoid the use of “mixed” products. This point is very important.
