Example markings of standard foreign LL shown in fig. 2.4. The marking of domestic LL usually consists of 2-3 letters and numbers.

Standard fluorescent lamps. Marking
Rice. 2.4. Marking of standard foreign fluorescent lamps

First letter L means luminescent.

The following letters mean emission color:

D - daytime;
HB - cold white;
B - white;
TB - warm white;
E - natural white;
K, F, 3, D, S - respectively: red, yellow, green, blue, blue;
UV - ultraviolet. Lamps with improved color rendering quality have the letter C after the letters denoting the color, and with the color rendering of especially high quality, the letters CZ.

At the end put the letters characterizing design features:

P - reflex;
U or U - U-shaped;
K - ring;
A - amalgam;
B - quick start.

The numbers indicate power in watts.

Examples. LB 40 - white fluorescent lamp with a power of 40 watts.

LDTs40-2 - fluorescent lamp of daylight color of radiation, improved color rendering with a power of 40 W, a deuce after power shows that the lamp is modernized, its bulb diameter has been reduced from 38 mm to 32 mm while maintaining light characteristics.

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 ... >>

Copolymers will increase HDD capacity by 5 times 28.11.2012

The capacity of a computer hard drive can be increased five times thanks to processes developed by chemists and engineers at the University of Texas at Austin. To do this, the researchers use a technique that relies on the self-organization of substances known as block copolymers. The results are described in a Science article. It also focuses on real world tests in collaboration with HGST, one of the leading innovators in the disc world.

"The world has seen a steady, exponential growth in the amount of information that can be stored in the memory of an electronic device over the past few decades, but the limit has already been reached and we are running into physical limits," said S. Grant Wilson, professor of chemistry and biochemistry at the College of Engineering. and natural sciences. "The entire global industry is currently struggling to get past the one terabit per square inch limit," Wilson said. - If we simply move the points even closer together using the existing method, they will spontaneously switch from time to time, and the storage properties of hard drives will be lost. Then trouble will happen. Can you imagine that one day your bank account will just spontaneously change?"

With modern manufacturing methods, zeros and ones are written as magnetic dots on a continuous metal surface. The closer the points are to each other, the more information can be stored there. But there is a limit to saturation. The points have become so close that any further increase in their number in close proximity to each other will cause them to begin to affect the magnetic fields of their neighbors and make them unstable. However, there is one important factor: if the points are reliably isolated from each other, they can be moved much closer to each other without any destabilization.

A group of professors Wilson and Ellison succeeded in developing special self-assembled copolymers that cover hard disk platters. As a result, a bizarre pattern of the thinnest copolymer tracks is obtained on its surface, which shields the magnetic points from each other. In this case, the density of points increases fivefold. The team has made great progress on a number of fronts. With the right temperature and the right conditions, researchers have been able to synthesize block copolymers with the right parameters, which independently form insulating elements from the smallest points in the world. And amazingly, this happens in just 30 seconds, which is also a record.
