Due to the fact that halogen lamps are only a modified version of conventional incandescent lamps, their properties are largely similar.

Through the use of the halogen cycle achieved two main benefits over vacuum and gas-filled lamps:

increased light output;
longer service life.

In addition, due to the higher temperature of the spiral, these lamps give light a slightly colder shade.

Light return halogen incandescent lamps are about twice as high as standard lamps of the same power and is 20-25 lm / W. Its value increases with increasing lamp power and decreasing its nominal voltage.

The brightness of the filament is slightly increased due to its increased temperature and can reach about 108 cd/m2. This makes halogen lamps ideal for use in spotlights and lens optics.

The brightness of lamps designed to directly replace frosted incandescent lamps is reduced by matting the bulb or by applying an internal diffusing coating to the bulb.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Microsoft data center at the bottom off the coast of Scotland 08.06.2018

A data center (DPC) typically generates a lot of heat and noise, and its location may be less than optimal. The solution to all three problems can be underwater data centers created by Microsoft as part of the Natic project.

After a long testing of prototypes, the developers put into operation the first trial center of its kind. The data center, the size of a standard 40-foot container, was towed out to sea off the coast of Scotland, loaded and secured to the seabed. The sealed enclosure contains 12 racks with 864 servers already handling workloads. In addition, a cooling system is mounted in the case, but it is much simpler than that which would be required in the traditional placement of the data center. When operating at full load, the center consumes almost 0,25 MW. Energy is supplied by cable from a wind farm located on land. Fiber optic connections are used for data transmission.

Over the next 12 months, project participants will carefully monitor all indicators - from energy consumption and humidity inside the case, to temperature and noise levels, as well as assess the impact on the environment. According to their plan, the underwater data center will be able to operate without maintenance for five to ten years.

Living offshore may seem counter-intuitive, but more than half of the world's population lives within 200 km of a coastline - an area with rich renewable energy potential. By locating data centers here, it is possible to provide local communities with high-speed access to online services. In addition, deployment is relatively fast. So if all goes according to plan, Project Natick could be the beginning of a transformation in how we deliver online resources to consumers.
