Development trend and latest progress of LED testing equipment

The development of the LED industry has put forward more requirements for LED testing equipment, making the research and development of testing equipment present the following trends:

(1) Testing expands to the upstream of the LED industry chain and supporting industries

The LED industry chain is relatively long, including upstream epitaxial growth, midstream chip manufacturing, and downstream chip packaging and application product manufacturing. The supporting industries include monocrystalline silicon , phosphors, drive circuits, etc. Existing LED testing equipment is mainly aimed at the midstream and downstream of the LED industry chain, especially LED online testing equipment is only aimed at LED chip packaging, which is far from meeting the actual testing needs.

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 LED testing equipment companies. It is reported that Hangzhou Yuanfang Optoelectronics has completed the prototype test of high-power LED fully automatic online testing equipment and started to develop online testing equipment for LED chips and LED application products, which is expected to be put into mass production soon.

(2) The LED standard system is constantly improving, 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 my country have stepped up their research on LED standardization. Therefore, the continuous specialization of LED testing equipment is the general trend. The relatively low-end LED testing equipment formed by slightly changing the traditional lighting photoelectric testing equipment will inevitably be eliminated by the market.
