Most lighting 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.
The High-mast Lamp is generally refers to the new lighting device which is composed of the steel taper light pole and the high power combination lamp frame of 15 meters or above.It consists of lamp holder, internal lamp, electric rod body and basic part.Lamp head modelling can according to user requirement, surroundings, lighting need specific and definite;The interior lamps are mainly composed of floodlights and projection lamps. The light source adopts NG400 high pressure sodium lamp, and the lighting radius is 60 meters.The bar body is usually a pyramid structure, which is made of steel plate, with a height of 15 to 40 meters, which consists of two to three sections.

In environments such as the New York subway station, security requirements are demanding, and LEDs must meet the fundamentals of high quality requirements.
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.
<br> <br> excellent classification ability LED manufacturers can produce not only a high quality chip, and has the ability to classify the LED package according to color, brightness, viewing angle and different voltage drop. 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.
