So called capsular halogen lamps got their name because of the corresponding shape of the flask (Fig. 5.4).

It is a piece of tube soldered on both sides with one-way wire entry. Inside the flask is a compact, usually double-folded spiral compared to the linear version.

Attention! Capsule lamps are designed in conjunction with the optical systems of special spotlights and therefore, despite being still directly connected to the network, they are not interchangeable with conventional incandescent lamps.

As a rule, lamps of this type have bayonet base B15d. Recently, miniature capsule models with pin bases have been developed, similar in design to the corresponding low-voltage lamps.

The use of special grades of glass and additional filter coatings in capsular lamp bulbs eliminates the problem of ultraviolet hazard. In addition, on the basis of high-voltage halogen capsules, some manufacturers also create lamps in a double bulb with threaded bases.

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. ... >>

Light bulb with vacuum cleaner 12.07.2015

English inventor James Dyson is known for his newly invented household appliances - vacuum cleaners, air purifiers, electric towels. He is also known for loud statements about his inventions. Now his son Jake Dyson has taken up the baton and announced the creation of an LED light bulb that can last for 37 years.

The main problem with LEDs is their cooling. Even though LEDs produce significantly less heat than incandescent bulbs, heat causes the brightness to dim over time and the color to fade. Dyson Jr. came up with the idea of using heat pipes to cool LEDs, as in large computer systems and space technology. However, they are also used to cool high-power LED lights, so Dyson's invention refers to the miniaturization of heat removal from the bulb using an aluminum radiator.

Thus, according to the author, the temperature is maintained at a level of 55°C, at which the phosphor coating of the LED is maintained for 37 years under normal use (12 hours of continuous use per day).

A "Dyson bulb", or rather, the entire lamp, in which 8 LEDs are built in, costs about $600. At the same time, the guarantee covers 2 years of work, and it is not clear what will happen in, say, 15 years. Therefore, it makes sense for exotic lovers to pay attention to Cree light bulbs. They are also LED, but the problem of heat dissipation in them is solved with the help of ring ribs on the bulb right above the lamp base.

In addition, Cree's new generation of light bulbs use holes in the base and top of the bulb to allow heat to be transferred by convection. And such a light bulb costs only $8.
