It is accepted that light affects our sleep cycle and health. In modern society, artificial light is ubiquitous and can affect the cycle of day and night as daylight. It is both an exciting opportunity and a potential concern for the solid-state lighting (SSL) industry. In this article, we discuss the non-visual aspects of light and how LED light sources can evolve for the benefit of human health and well-being. In the early 2000s, based on groundbreaking research on light and sleep, researchers found an unknown cell in our retina: ipRGCs. These cells are light-sensitive. Such cells can receive light and connect directly to the part of our brain that regulates sleep patterns, affecting the circadian rhythm. The most important of these cells is that they are sensitive to blue light and their peak sensitivity is around 450-480 nm. When stimulated by light, they send out a wake-up signal. This signal can be observed in a variety of physiological responses; for example, it stops our b

Since the 1940s, the application and promotion of nutrition liquid cultivation technology based on the theory of "mineral nutrition" and the first artificial plantation established by the American plant physiology and horticulturalist FWWent in Pasadena, California in 1949 The revolutionary breakthrough in the "artificial simulated eco-environment" triggered by the climate chamber has given rise to mature conditions for the emergence of plant factories. 1957 Denmark was born the world's first plant factory. After Japan and other countries have followed. The term "plant factory" was first proposed by Japan and in the narrow sense refers to artificial light-type plant production systems. In a workshop-simulated environment, nutrient solutions replace the soil and deliver enough nutrients to the plants. In the process of plant growth, the temperature, humidity, carbon dioxide concentration is also controlled by the computer in a controlled range. I

Over the past two decades, LEDs have evolved from traditional stand-alone bulb lighting applications to total lighting system designs and are now evolving into digital LED systems including networking or network lighting, smart lighting and people-focused lighting (HCL). Since LEDs are sources of solid-state lighting (SSL), this evolution is unbelievable, but anything is possible. However, in the face of fierce competition, the commercialization of LED and LED modules has slowed the progress of LED lighting technology. Over the years, the LED industry has focused on cost advantages over designs, but industry giants are now placing more emphasis on developing more advanced LED lighting designs. That existing LED lighting company will discuss how to accelerate these technology-focused transitions and how to gain a deeper understanding of current market issues to unlock the full potential of smart lighting and the Internet of Things (IoT)? Recently, many lighting companies are pushin
