In the era of globalizatton, internattonal cooperatton and exchanges are indispensable for the development and maturity of an emerging industry. To make SSL bigger and stronger in the world, there must be close interactton between R&D, manufacturing and applicatton. The development of SSL in China cannot be separated from the cooperatton of other countries, and the development of global SSL also needs China. So, it is this combinatton of chance and necessity that gave the birth to ISA. 

Since its establishment, ISA by aligning the SSL industry and R&D resources worldwide, provides a global and inclusive forum for the solutton of science and technology, manufacturing, standard and design issues. The aims of ISA have been to promote healthy, safe and sustainable lighttng worldwide, contribute to foster a “ecosystem” suitable for the global SSL development and applicatton, respond social demands and provide more valueadded services for members so as to improve the living quality of people and sustainable development of human society. 

Under the guidance by the ISA Council of Management and Board of Advisors, with the strong support of members, ISA made quite a lot achievements in standards development, cooperatton with emerging economies, industrial report development, and in the areas of smart lighttng, deep UV LED for the epidemic, LiFi as well as to promote cooperatton between countries and regions. All of these efforts have won the recognitton and commend from internattonal community. Through the joint efforts of scienttsts, engineers, entrepreneurs and the whole society, SSL has been available worldwide with fruittul results.

 SSL has undergone tremendous changes and basically taken the place of tradittonal lighttng. In terms of energy saving and emission reductton, lighttng effect improvement and lighttng quality improvement SSL has made signiffcant progress. SSL has now entered the ffeld beyond lighttng such as smart lighttng, plant lighttng, breeding lighttng and medical health, etc. Moreover, it conttnues to go beyond people’s imaginatton and expand broader applicatton space such as LiFi, Micro-Led, deep-UV sensor, etc. 

The SSL is also being challenged. Firstly, people-oriented lighttng which is closer to sun-light, the lighttng which can better protect eyesight, and the lighttng which could keep the real look of night without causing light pollutton. Secondly, the broader applicatton of SSL needs to be explored in the digital society. For example, it may address COVID-19, diseases spread by some vectors, give play to its role in smart city, IoT and 5G era, enter ffelds such as informatton display, VR, transparent display and ffexible display. 

Demands drive the development of industry and problems bring up soluttons. Humans will advance in science and technology progress and conttnuous innovatton. Let’s make our joint efforts to promote more perfect and natural light to spread around the world.
