Comments on the article

In standard lamps, a cheap broadband phosphor is used - calcium and magnesium halophosphate activated by antimony, manganese (HFC). Lack of of these lamps - a low color rendering index Ra = 50-70, which leads to a distorted color rendering of illuminated objects.

Dignity - low cost (2-4 times cheaper than lamps with high color rendering). It is these LLs that domestic manufacturers are known for: OAO SVET (Smolensk Electric Lamp Plant), smolensk.ru/user/svet; JSC "LISMA", Saransk, lisma-lighting.ru.

Council. Lamps of this type are recommended for use where precise definition of color shades is not required: for lighting basements, garages, warehouses, outdoor lighting.

It is not uncommon for a consumer, having learned about the cost-effectiveness of using LL, decided to replace incandescent lamps and purchased LL with a low color rendering index and a color temperature of 6000 K of a bluish tint. Incandescent lamps have a color rendering index Ra = 95 and a color temperature of 2700 K - a warm color. As a result, in the light of such a LL, the usual surrounding objects changed their color shade. As a result of this, discomfort arises and irritation from an unsuccessful experiment appears.

This fully applies to compact LL (KLL) Chinese-Polish-Turkish production with a non-standardized color rendering index.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

optical diode 03.05.2018

Researchers at the US National Physical Laboratory (NPL) have created a first-of-its-kind optical diode made up of light that can be used in miniaturized photonic and photonic-electronic circuits. This optical diode, like its electronic counterpart, transmits light in only one direction, but its main advantage is the small dimensions of the device and the absence of the need for large powerful permanent magnets, which are part of other types of optical diodes.

Diodes are indispensable components of most electronic circuits. They allow electricity to flow in one direction and block the flow of electricity in the opposite direction. This diode function is used in a wide variety of electronics applications, from the detection of extremely weak radio signals to high power power rectifiers capable of converting alternating electrical current into direct current.

The basis of the new optical diode is a ring resonator, a glass ring mounted on the surface of a silicon chip. The size of this ring is approximately the diameter of a human hair, and the diode effect occurs by creating a rotating optical field inside the resonator.

The ring resonator is pumped with light from an external source. "Given the tiny size of the device itself, the power density of the light circulating in the resonator is comparable to the output of all floodlights used to illuminate a large stadium," says Dr. Jonathan Silver (Dr. Jonathan Silver), lead researcher, - "Due to such a high concentration of energy in the resonator in It produces an optical diode, which works due to one of the types of interaction of light with light, called the Kerr effect.

Experiments carried out with the device showed that inside the glass resonators the electromagnetic field rotates clockwise. At the same time, the light supplied to the device in the same direction passes through it unhindered, and the light supplied in the counterclockwise direction is blocked.

"The presence of such a diode opens the way to the creation of low-cost microphotonic circuits and chips that can become the basis of optical computing technologies," says Pascal Del'Haye, one of the researchers, "In addition, new diodes can be used in field of optical telecommunications, enabling more efficient use of existing fiber optic networks.
