Seoul Semiconductor SunLike LED is the safest

25.11.2017

Seoul Semiconductor, an LED specialist, announced that its SunLike lighting LED, which is closest to the spectrum of sunlight, has received RG 1 Eye Safety certification. This is the highest level of safety for 25W COB LEDs.

The Eye Safety certification is based on an analysis of the emission spectrum. It is defined in the international standard CIE S 009:2002 and takes into account the factors of exposure to the eyes and skin described in the IEC / EN 62471 standard. The highest level of No Risk is received by sources that do not pose a "photobiological" hazard to humans. Level RG 1 (Low Risk) means that there is no risk in normal daily use. Level RG 2 (Intermediate Risk) indicates that there is no risk, but discomfort due to bright light or heat is possible. Finally, an RG level of 3 (High Risk) indicates that the light source is dangerous even with momentary exposure.

In addition to safety, the manufacturer also attributes good color rendering to the advantages of SunLike LEDs. These LEDs are expected to be widely used in home and office lighting, educational institutions, medical institutions, museums, shops and other places where safe and natural lighting is required.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Pollination with soap bubbles 26.06.2020

Researchers in Japan have developed a bubble pollination method that is as effective as doing it by hand.

The search for new methods of pollination of agricultural crops is due to a decrease in the population of wild insects and diseases of honey bee colonies.

The author of the development is Professor Eijiro Miyako, he came up with the idea of ​​mixing pollen with soapy water, and then filling a special gun with liquid. The technology has already been tested in practice: scientists “fired” a pear orchard with pollen bubbles. Bubbles have a large surface area, are easy to disperse, and are not very expensive, making them ideal for this task.

The team estimated that every flower in the garden was hit by two to ten bubbles. As further observations showed, 95% of the flowers set fruit. Scientists noted that the method of manual pollination of flowers brings the same result, but it requires much more effort.

The scientist plans to improve the technology and attract drones piloted over the field. So it will be possible to increase the scale of work and improve accuracy.
