Development trend and latest development of LED testing equipment

The development of the LED industry has put forward more requirements for LED testing equipment, which makes the following trends in the development of testing equipment:

(1) Detection to the upstream of the LED industry chain and the expansion of supporting industries

The LED industry chain is long, including upstream epitaxial growth, midstream chip manufacturing and downstream chip packaging and application product manufacturing. The supporting industries include monocrystalline silicon, phosphors, and driver circuits. The existing LED detection equipment is mainly for the middle and lower reaches of the LED industry chain, especially the LED online detection equipment is only for the LED chip package, which is far from meeting the actual detection requirements.

Laboratory testing equipment for upstream epitaxial growth and supporting industries, as well as online testing equipment for LED chips, LED packaging (high power, etc.), LED modules, and LED application products have become the focus of research and development of LED testing equipment companies. It is reported that Hangzhou Yuanfang Optoelectronics has completed the prototype test of high-power LED automatic on-line testing equipment, and started the development of online testing equipment for LED chips and LED application products, and is expected to be put into mass production soon.

(2) The LED standard system is continuously improved, and the testing equipment is more specialized.

The LED industry standard system has not been perfected, and the lack of relevant standards has always been a prominent problem that restricts the rapid development of the LED industry. In recent years, the International Commission on Illumination (CIE), the United States, the European Union, Japan, and China are all stepping up LED standardization research. Therefore, the continuous specialization of LED testing equipment is the trend of the times. The relatively low-end LED detection equipment that has been slightly changed to the traditional lighting photoelectric detection equipment will be eliminated by the market.
