In table. 2.4 presented comparative characteristic of light output of lamps of different types.

Table 2.4. Comparative characteristic of light output LL with a color temperature of 4000 K

Hack and predictor Aviator. In terms of "price/quality" ratio, lamps with a three-band phosphor (8th series, color code - 90xx) are leaders. Having the highest light output - 9 lm / W, good color rendering and reasonable price, they are a compromise between cheap standard and expensive (but with a high color rendering index) five-lane LL of the nine hundredth series (color code - XNUMXxx).

The most complete transfer of the color palette of the environment creates more comfortable conditions for perception. Lamps of improved color rendering are used not only where, with the help of general lighting, it is necessary to most clearly convey the colors and shades of surrounding objects, but also for lighting residential premises and workplaces.

As already noted, domestic lamps with improved color rendering have the letters C or CC in their marking. For example, LEC 40-2, LTBCC 20.

Deciphering the international three-digit color code (color rendering index plus color temperature), used in the marking of lamps with improved color rendering, is given in Table. 2.5.

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 ... >>

Random news from the Archive Subminiature TransferJet Module 15.03.2014 Specialists of the Japanese company Toshiba have created the world's smallest wireless communication module and an antenna for it in the form of a flexible printed circuit board. These components are compatible with TransferJet short range wireless technology. The operation of TransferJet is based on the principle of a resonant transformer. The transmission speed reaches 375 Mbps. The developer expects that TransferJet technology will be widely used in mobile devices due to low power consumption, high speed and exceptional ease of use. The company believes that the growing demand for high-speed wireless communication between electronic devices will increase the demand for modules and antennas (essentially resonant transformer windings) that can be easily integrated into consumer electronics devices. The module in question measures 4,8 x 4,8 x 1,0mm and the PCB-style antenna is only 0,12mm thick. The key to miniaturization was the volumetric integration of the chip onto the module substrate and the use of molecular bonding technology. The manufacturer notes that with this, measures were taken to reduce parasitic capacitance, which could adversely affect the transmission of a signal with a spectrum of 560 MHz. Introductory module samples are already available, flexible antenna samples will appear this month.
