Fan advertising machine LED naked eye 3D holographic projection suspended video playback animation show cool rotation Recently, a foreign friend displayed a cool LED "fan" on Instagram, this magic "fan" can show 3D stereoscopic and constantly changing graphics. This has a magical effect of the "fan" aroused strong interest from the majority of users, after all, this "fan" brought back from China, we ourselves have never seen. Many people have asked, where you can buy. www.likeyli.com Mr likey could help you . In fact, a closer look blogger's post, you can find that this so-called "fan" is just a vivid name, in fact, it is a "rotating LED bar," manufacturers call it "naked eye 3D holographic display machine". Its true look is long. And the fan's look is still far worse. This seemingly high-end technology actually takes advantage of a common principle, Persistence of Vision (POV). Th...

Blue affect the circadian rhythm, purple LED will replace the standard blue LED?

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...

Researcher at the Chinese Academy of Sciences: Three to five years later, a large number of commercial plant factories will emerge

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...

Transformation of intelligent lighting? First look at this ...

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...

LED lights can also be embedded into the road when the zebra crossing? Smart city new direction

图片
A new embedded LED road light traffic system has been put into trial in London to detect pedestrians and other vehicles, and according to the road conditions in real-time changes in road lighting and pipelines to alert drivers of possible danger. Especially when there are pedestrians or bicycles in the blind spot of car driver's eyes, the pavement will display a red light warning. Embedded LED pavement, the system also includes high-definition camera, used to capture pedestrian and vehicle information, auxiliary system to make real-time feedback. The zebra crossing and road safety have always been important and complex parts of the mass transit system. However, from the embryonic form of the zebra crossing design in the 1940s to the highly developed traffic, people have not changed much in the way of crossing the road. The increase of traffic accidents make the perfect zebra crossing and pedestrian traffic system become the necessary consideration for the design of smart ...

Breakthrough in optical communication technology, the first LiFi LED lighting panel come out

图片
With the rapid development of mobile networks and smart products, it also drives network-related services. As consumers demand more and more capacity and speed from the network, optical communication technologies emerge as the times require. Currently fiber is the most common optical communication technology, with LED or laser diode (LD) as a transmitter. The new generation of optical communications for wireless optical communications (LiFi) technology to LED light, infrared or near UV as the transmission medium, combined with lighting technology and communications dual-use, is expected to become an indispensable smart home technology. Compared with WiFi technology, LiFi transmission speed faster, and can avoid electromagnetic interference, and LiFi technology and a breakthrough recently, the United States company VLNComm developed the first LiFi LED lighting panel, and at this year's Consumer Electronics Show. The LumiNex lighting panel delivers 108Mbps download speed with Lumi...
