Several Keys to the High Quality LED

Third-party testing



In order to eliminate the injustices that exist in the test, many companies have commissioned a third party to test LED assembly and circuit structure. In the testing process, and at the same time, pressure, temperature cycling, fixed voltage / change current fixed / change test and the test in other harsh environmental conditions decide whether the LED(such as flexible led strip lights) meets the requirements of the application. The occurrence of the large number of parameter changes before and after the test should be recorded while monitoring the changes in the measured LED brightness, color, and the voltage drop. In addition, the assembly technology has more impact than the performance of the LED chip to some extent. The design engineer should ask LED suppliers for the LED reliability specification, and LED assembly should be tested to ensure higher brightness. Some good LED suppliers can ensure the reliability of the LED assembly technology for three years or longer, and can provide high quality LED and the appropriate design for specific applications, including the final LED products.

The importance of LED detection

In the early 1990s, LED was used in the brake lights for cars and trucks. Some LED design soon appeared inconsistency on the performance indicators, and soon be burned down, the reason may be the led power supply quality, perhaps completely the design of the product. Until now, in the traffic lights, LED becomes more suitable light source, and this phenomenon was only great importance. If the stress tests or accelerated life cycle testing has been done, then LED or LED assembly can be considered as high-quality or qualified, and can be used in reliability occasion.

Rational usage of LED

Not every application needs high-quality LED assembly technology. If the assembly of the LED does not meet the requirements of the harsh environment, the application does not have larger security risk, or, if the maintenance costs of the final product are not very high, the use of the differential of some of the assembly technique may be more appropriate.

The cost of LED light

The most fundamental content is the LED must be affordable. So, in the limit of cost requirements, it is necessary to consider the level of supplier product packaging, assembly design experience and testing. The design that meets the application and market demand is the most effective means of service to end users. If the application requires high-end solutions, the chip vendor selection, design experience, and tests are the factors that you should consider. If you do not consider the sales price of the high-end products, you should consider very carefully the difference between good and bad LED other relevant factors. LED suppliers with packaging grade classification ability, as well as to the reliability, accelerated life cycle testing vendors is a long-term cooperation, which helps manufacturers with a more reliable LED develop high-end products.
