Most designers believe that the quality of all LED products is the same. However, there are many manufacturers and suppliers of LEDs , and Asian manufacturers supply low-cost LEDs to the world. Surprisingly, only a small percentage of these manufacturers are able to produce high quality LEDs. For applications that are only used as a simple indicator, low quality LEDs are sufficient. However, high quality LEDs must be used in many areas requiring consistency, reliability, solid state indication or lighting, especially in harsh environments such as highways, military/aviation, and industrial applications.
Fundamental factor
What are the factors that distinguish the quality of LEDs? How to tell the difference between the two LEDs? In fact, choosing a high-quality LED can start from the chip until assembly is complete, and there are many factors to consider during this period. Tier-OneLED manufacturing companies are able to produce superior, consistent wafers that are made from high-quality LED manufacturing materials to produce superior chips. The chemical materials used in the wafer production process are quite important factors in determining the performance of all LED performance specifications. A 2-inch wafer can cut more than 6,000 LED chips , and only the performance of individual chips is different from the overall one. Chips made by a good chip maker have very little difference in color, brightness, and voltage drop. When the LED chip package is completed, many of their performance indicators may have great differences, such as viewing angle. In addition, the influence of the encapsulating material is also considerable, for example, silicone is better than epoxy resin.
Classification ability
Good LED manufacturers can not only manufacture high quality chips, but also have the ability to classify and package LEDs based on their color, brightness, voltage drop and viewing angle. High-quality LED suppliers offer customers products with consistent work characteristics, while lower-quality LED suppliers can only provide LEDs that are similar to "mixed". For high-end, quality-critical applications, such as boundary lights for airport runways, FAA-level color and brightness specifications must be met. To ensure performance and safety, the consistency of LED packaging is also strictly limited. LEDs with poorer packaging levels are used in demanding applications that can lead to premature failures and other inconsistencies, which can lead to major accidents. In order to avoid equipment downtime and to ensure reliable operating characteristics of the LEDs specified in the design, it is important to avoid the use of "mixed" products in high-end and quality-critical applications.
