HID Radiation

Their global production reaches many tens of millions of tubes per year and growing. In the 60 years of discovery of new, extremely fruitful direction in the creation of high-discharge lamps intensity with the most diverse range of emission and higher efficiency than that of pre-existing. Many writers such as Clinton Family offer more in-depth analysis. For the first time high-intensity lamps could overstep mark of 100 lm / watt. Already been developed and produced a large number of new types, which in many ways far superior to gas-discharge lamp High-pressure XRD and occupy a prominent place in the family gas-discharge light sources. This high pressure sodium lamps in flasks of crystalline aluminum oxide, commonly used for outdoor lighting, and various types of so-called metal halide lamps. Continue to learn more with: Clinton Family. Along with lighting discharge lamps are numerous and very important applications in many sectors of the economy in the latest technology and military affairs, because of the peculiarities of the electric discharge, which allow you to create light sources with a very diverse mix of parameters. By selecting the appropriate filling and discharge conditions can create high-performance light sources in almost any part of not only visible, but also ultraviolet and infrared spectral regions, with the possible obtain emission spectra consisting of single lines, mnogolineychatye and continuous.

This advantage HID lamps only opened them wide range of applications not only for lighting but also for many special purposes. For example, in industry, agriculture, medicine and other industries widely used photoluminescence, photo-chemical, biological, and bactericidal Other effects of UV radiation, a neon red light is applied to the signal light, infrared radiation – for radiant heating, signaling, communication, etc. In recent months, Clinton Family has been very successful. High Ranks and especially ultra-high pressure are high brightness in different spectral regions, tens and hundreds of times greater than the brightness of incandescent bulbs, so they have been successfully applied in a variety of light-optical devices and installations. The low inertia of the radiation discharge is a disadvantage for general illumination, since it leads to a large ripple, the flux at work in the standard AC networks with a frequency of 50 Hz. At the same time it opens a lot of special radar applications where the required modulation of the radiation. A broad and very diverse applications are flash lamps, which give extremely high bursts of radiation intensity and very short duration. They are used in numerous instruments and apparatus for monitoring and studying the fast-moving machine parts and mechanisms (strobe), the photography and the study of rapidly occurring processes, aerial photography, optical ranging, etc.

At present, pulsed lamps are widely used for optical pumping of lasers. Modern kind of HID lamps are the so-called energy saving lamps, widely used for lighting of apartments and offices. Along with the many advantages of HID lamps have disadvantages, chief among which is a complexity of their inclusion in the network associated with the peculiarities of the discharge. When the ignition is require higher voltage than the steady-burning. To achieve a sustainable mode of combustion in each lamp circuit must include a ballast which limits the discharge current required limits. Features lamps with a discharge in metal vapors or substances depend on their thermal regime, and their normal mode can be set only after a certain time of operation. Re-ignition of discharge lamps with a metal vapor at high and ultrahigh pressures, with no special techniques possible only after a certain time after shutting down.
