Importance of LED Test Methods and the Standard of LED
In order to develop the LED lighting technology, developed countries have attached great importance to the test methods and the standard research of LED. For example the American National institute of Standards and Technology (NIST) organized the international well-known test experts to conduct the LED testing research and mainly studied LED lighting characteristics, temperature characteristic [...]
LED Quality Evaluation
Semiconductor light emitting diode (LED) has many new problems in the aspect of quality evaluation and LED test method because of its characteristics such as small volume, directional light emission, high brightness, PN electrical characteristics and so on. Different applications determine the performance requirements of LED products. From the aspect of the optical proper including [...]
