The advantages of the high brightness of the spiral for creating directional light are fully realized in mirror halogen lamps, which are a linear or capsular halogen lamp placed in a flask with a reflector. Lamps in pressed PAR bulbs are the most widely used, although there are also traditional options (bulb type R).

Initially, PAR38, PAR56 and PAR64 bulbs, traditional for incandescent lamps, were used for mirror halogen lamps, but the success of this combination led to the additional development of PAR30, PAR20 and even PAR16 bulbs (Fig. 5.5).

Halogen lamps of these series successfully replace incandescent lamps in R95, R63 and R50 bulbs with corresponding threaded bases, and the minimum radiation angle is no longer 30, but only 10 °. There are other, somewhat less common modifications of pressed halogen lamp bulbs.

It is important to pay attention to the fact that the PAR30 flask has two modifications that differ in the overall length of the body (90,5 and 119 mm). Depending on the type of luminaire, they may not be interchangeable, and when choosing lamps to replace, it is necessary to take into account the dimensions of specific types. The 90,5 mm length is currently the de facto standard for the PAR30 flask.

The trend of the general miniaturization of halogen lamps in relation to mirror lamps manifested itself in the creation of miniature models with a diameter of 51 mm with a pin-swivel base GU10 and GZ10 (Fig. 5.6).

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. ... >>

OWC Mercury Elite Pro Dual 10TB External Drives 19.05.2014

Other World Computing (OWC) announced the availability of the high-performance 10TB Mercury Elite Pro Dual external storage.

The drive is equipped with two bays for installing 3,5-inch hard drives with a capacity of 5 TB each. Hard drives can be configured in a RAID 0 array to achieve the highest data transfer speed or in a RAID 1 array to increase reliability through mirroring.

The Mercury Elite Pro Dual has two Thunderbolt ports and one USB 3.0 interface. The declared data transfer rate in read mode reaches 442 MB / s, in write mode - 424 MB / s.

Drives are designed for intensive information exchange in applications such as video processing, graphics, backup of large amounts of data, etc.

Mercury Elite Pro Dual dimensions are 225x132x70 mm. The package includes high quality Thunderbolt and USB connection cables.

The cost of a 10TB drive is $950. You can also purchase 2TB, 4TB, 6TB, and 8TB versions for $430 to $760. The Mercury Elite Pro Dual without hard drives installed will cost $300.
