Outdoor lighting is one of the first few types of lighting that turns to LEDs earlier, and the energy efficiency benefits, albeit highly, have given rise to new challenges that will keep outdoor lighting designers on standby. The following are the top 10 challenges in the new year. Glare This problem will not disappear. People are increasingly realizing that too many poorly-controlled lamps are installed when the LED is beginning to popularize. And in some places, low-color lighting is also popular with residents dislike. 2. The end of private initiative financing (PFI) Large-scale private financing LED era is coming to an end. But when the dust settles, authorities in some places are still wondering whether these items are worth the money, at the expense of lighting quality. 3 electric car charging The general government believes that its street lamp network can provide the perfect charging solution for the coming era of electric vehicles. However, this is not the case, t...

Japan's Yomiuri Shimbun reported that Japanese researchers, lawmakers and business people all hope that LED products can be made from rare earth metals in the deep sea off the coast of Japan and applied to Japan's Olympic and Paralympic Games in 2020. Rare earth metals are highly concentrated in the outer seas of Minami Torishima, Japan's easternmost island of Ogasawara. Rare earths in the seabed 5,000 meters deep are estimated to be enough for 200 years in Japan. Yasuhiro Kato, a professor at the University of Tokyo in Japan, and his research team succeeded in extracting (Yttrium) and (Cerium) from rare earth metals in the sea out of South Island as LED luminescent materials. Several Liberal Democrats have proposed to the government that they hope to use the LEDs for the Olympic Games in Japan. The government is also considering commercializing the LEDs for use in Olympic venues to show foreign guests the richness of Japan's marine resources. If large-scale ex...

Optical performance (light distribution) The optical properties of LED lamps mainly relate to the performance requirements in terms of luminosity, spectrum and colorimetry. According to the industry standard "semiconductor light-emitting diode test method", there are luminous peak wavelength, spectral radiation bandwidth, axial luminous intensity angle, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color purity and dominant wavelength Color index and other parameters.

According to a study published in the journal "Hippocampus," long-term exposure to dim conditions can alter the structure of the brain, impairing our memory and learning ability. Researchers at Michigan State University, led by Dr. Lily Yan, studied the brains of Arvicanthis niloticus after being exposed to dim light for four weeks. The results showed that important brain areas of learning and memory in their brains lost approximately 30% of their ability and did poorly on the space tasks they had previously trained on. On the other hand, animals exposed to bright light showed a clear improvement in their spatial tasks. In addition, these grass hamsters, previously exposed to dim light, regained their brain capacity and performance completely after being exposed to light for four weeks. Associate Professor Antonio Nunez said: "When we exposed rats to dim light, mimicking cloudy winter in the Midwest or typical indoor lighting, these animals showed signs of lea...

It is reported that hospitals and laboratories often use ultraviolet light to kill bacteria, but this approach has a major drawback, that is, causing harm to humans. As a result, UV light can only be sterilized in unattended operating rooms and in empty laboratory enclosures. Researchers have now found that shorter wavelengths of germicidal UV light may be harmless to the human body and, according to theory, have developed it into a new tool that can be used in schools, crowded aircraft, food processing plants, and even operating and laboratory laboratories And other places to slow down the spread of the disease. Ultraviolet light sterilizes bacteria by disrupting the molecular bonds that bind the bacterial genetic material to the protein. Among them, the most commonly used is 254nm light, which contains a short UV wavelength, the so-called class C, however, it can penetrate the skin and eyes, leading to cancer and cataracts and other diseases. To this end, David Brenner, a phys...

Today, outside the office, parking lots and driveways have a common element that can be hard to find: invisible lighting. This is because invisible lighting designs make the luminaire less noticeable in the environment being observed. In this article, Mr Likey li, Marketing Manager at Likey Lighting, will introduce invisible lighting designs and their impact on the environment. What is invisible lighting design? Invisible lighting design refers to a way of selecting and applying lighting without compromising the visual clarity of the surrounding environment. The environment can include buildings, driveways or parking spaces, hard landscapes or natural landscapes. Essentially, people who are observers or who use this space do not notice the lighting. 2. What is the main goal of invisible lighting design? The main goal of invisible lighting design is to ensure that the lighting equipment: (1) complements the design language of the hardscape or surrounding building structure; a...

There are many advantages of intelligent lighting: saving energy and making our homes, workplaces, hospitals and other places more comfortable. But in fact, intelligent lighting applications are still relatively uncommon, partly due to the commonly used wireless technology. If intelligent lighting is to be convenient and intuitive, wireless control must be carried out by mobile devices such as smart phones, tablet computers or wearable devices. The problem is that wireless technologies that have been tested in intelligent lighting (including Wi-Fi and ZigBee) are not perfectly matched with intelligent lighting. Why ZigBee and Wi-Fi are not so suitable for intelligent lighting First of all, ZigBee is not found in most mobile phones or tablet computers, which means you need to add a cryptographic dog or gateway between control devices and lighting. In addition to increase the cost of the whole system, a single gateway brings additional risk: once the device strikes, you may have no c...
