Раскрытие изобретения. Disclosure of the invention.
Задачей изобретения является обеспечение максимальной безопасности и энергетической экономичности осветительного устройства. The objective of the invention is to ensure maximum safety and energy efficiency of the lighting device.
Техническими результатами являются: Technical results are:
- полное отсутствие в итоговом спектре следов исходного лазерного излучения, - the complete absence in the final spectrum of traces of the original laser radiation,
- КПД, приближенный к максимально теоретически возможному.
Для пояснения технического результата используем понятие абсолютно чёрного тела— это физическая идеализация, применяемая в термодинамике - тело, поглощающее всё падающее на него электромагнитное излучение во всех диапазонах и ничего не отражающее. Несмотря на название, абсолютно чёрное тело само может испускать электромагнитное излучение любой частоты и визуально иметь цвет. Спектр излучения абсолютно чёрного тела определяется только его температурой. - Efficiency close to the maximum theoretically possible. To clarify the technical result, we use the concept of a completely black body — this is a physical idealization used in thermodynamics — a body that absorbs all electromagnetic radiation incident on it in all ranges and does not reflect anything. Despite the name, a completely black body can itself emit electromagnetic radiation of any frequency and visually have color. The emission spectrum of an absolutely black body is determined only by its temperature.
Абсолютно чёрных тел в природе не существует, поэтому в физике используется модель. Она представляет собой замкнутую полость с небольшим отверстием. Свет, попадающий внутрь сквозь это отверстие, после многократных отражений будет полностью поглощён, и отверстие снаружи будет выглядеть совершенно чёрным. Поскольку излучение, испущенное внутренними стенками полости, прежде, чем выйдет (отверстие очень мало), в подавляющей доле случаев претерпит огромное количество новых поглощений и излучений, то можно с уверенностью сказать, что излучение внутри полости находится в термодинамическом равновесии со стенками и, соответственно, вся попавшая в отверстие энергия будет преобразована в световое излучение. Absolutely black bodies do not exist in nature, therefore a model is used in physics. It is a closed cavity with a small hole. The light entering inside through this hole will be completely absorbed after multiple reflections, and the hole outside will look completely black. Since the radiation emitted by the internal walls of the cavity before exiting (the hole is very small), in the overwhelming majority of cases will undergo a huge number of new absorption and radiation, it can be safely said that the radiation inside the cavity is in thermodynamic equilibrium with the walls and, accordingly, all energy that enters the hole will be converted into light radiation.
Все технические результаты достигаются за счет того, что источник света на Фиг.1 содержит источник энергии (1), корпус (6), рассеиватель в виде модели абсолютно черного тела в виде прозрачной замкнутой полости с небольшим отверстием (4), на внешнюю и/или на внутреннюю сторону рассеивателя (4) нанесено вещество (3), способное преобразовывать поглощаемую им энергию (2) (излучаемую источником энергии), в световое излучение (5), и от прототипа отличается тем, что в рассеиватель (4) выполнен в виде модели абсолютно черного тела в виде прозрачной замкнутой полости с небольшим отверстием. All technical results are achieved due to the fact that the light source in Fig. 1 contains an energy source (1), a housing (6), a diffuser in the form of a model of a completely black body in the form of a transparent closed cavity with a small hole (4), to the external and / or a substance (3) is deposited on the inside of the diffuser (4), capable of converting the energy absorbed by it (2) (emitted by the energy source) into light radiation (5), and differs from the prototype in that the diffuser (4) is made in the form absolutely black body models in the form of a transparent closed olosti with a small hole.
Лазер - это устройство в котором происходит усиление света посредством вынужденного излучения. Основным элементов лазера является квантовый генератор - устройство, преобразующее энергию накачки (световую, электрическую, тепловую, химическую и др.) в энергию когерентного, монохроматического, поляризованного и узконаправленного потока излучения.
В частном случае, источник света может быть выполнен так, что в качестве вещества (3), способного преобразовывать поглощаемую им энергию (2) в световое излучение (5) используют люминофор. A laser is a device in which light is amplified by stimulated emission. The main elements of the laser is a quantum generator - a device that converts pump energy (light, electric, thermal, chemical, etc.) into the energy of a coherent, monochromatic, polarized, and narrowly directed radiation flux. In a particular case, the light source can be made so that a phosphor is used as a substance (3) capable of converting the energy absorbed by it (2) into light radiation (5).
Люминофор (от лат. lumen— свет и др.-греч. φορός— несущий)— вещество, способное преобразовывать поглощаемую им энергию в световое излучение (люминесцировать) . Luminophore (from Latin lumen — light and other Greek phoρός — bearing) is a substance capable of converting the energy absorbed by it into light radiation (luminesce).
По химической природе люминофоры разделяются на неорганические, большинство из которых относится к кристаллофосфорам, и органические. Свечение неорганических люминофоров (кристаллофосфоров) обусловлено в большинстве случаев присутствием посторонних катионов, содержащихся в малых количествах (от 2 % до 0,0001 %). By their chemical nature, phosphors are divided into inorganic, most of which belong to crystallophosphors, and organic. The luminescence of inorganic phosphors (crystallophosphors) is due in most cases to the presence of extraneous cations contained in small amounts (from 2% to 0.0001%).
Такие примеси (активаторы) обычно являются ионами металлов; например, свечение сульфида цинка активируется ионом меди. Неорганические люминофоры применяют в люминесцентных лампах, электронно-лучевых трубках, для изготовления рентгеновских экранов, служат индикаторами радиации и др. Органические люминофоры (люмогены) применяют для изготовления ярких флуоресцентных красок, люминесцирующих материалов, используют в чувствительном люминесцентном анализе в химии, биологии, медицине и криминалистике. Such impurities (activators) are usually metal ions; for example, the glow of zinc sulfide is activated by a copper ion. Inorganic phosphors are used in fluorescent lamps, cathode ray tubes, for the manufacture of X-ray screens, serve as indicators of radiation, etc. Organic phosphors (luminogens) are used for the manufacture of bright fluorescent inks, luminescent materials, and are used in sensitive luminescent analysis in chemistry, biology, medicine forensics.
Сведения, подтверждающие возможность осуществления изобретения.Information confirming the possibility of carrying out the invention.
В источнике света два основных элемента: люминофор и лазер. Излучаемая лазером (1) энергия (2) (видимая и/или невидимая глазом) попадает в рассеиватель (4), внутри и/или снаружи покрытый люминофором (3) и тот светится (5). The light source has two main elements: a phosphor and a laser. The energy (2) emitted by the laser (1) (visible and / or invisible to the eye) enters the diffuser (4), inside and / or outside it is covered with a phosphor (3) and it glows (5).
Работает устройство следующим образом: излучение от лазера падает внутрь рассеивателя с веществом, способное преобразовывать поглощаемую им энергию в световое излучение, в частности, люминофор, который начинает светиться. The device operates as follows: the radiation from the laser falls into the diffuser with a substance that can convert the energy absorbed by it into light radiation, in particular, a phosphor that starts to glow.
В источнике света видимый свет излучается в основном люминофором, который в свою очередь светится под воздействием излучения лазера. In a light source, visible light is emitted mainly by a phosphor, which in turn glows under the influence of laser radiation.
Световая отдача такого источника света гораздо выше, чем у ламп накаливания аналогичной мощности и люминесцентных газоразрядных ламп за
счет использования лазера. Срок службы такого источника света может в 10 раз и более превышать срок службы газоразрядных ламп и ламп накаливания. Нагревание лазера существенно меньше, чем у газоразрядной лампы. Для работы источника света не нужна ртуть. В итоговом спектре нет следов исходного лазерного излучения, КПД приближен к максимально теоретически возможному за счет свойств абсолютно черного тела. The luminous efficiency of such a light source is much higher than that of incandescent lamps of similar power and fluorescent discharge lamps for expense of using a laser. The service life of such a light source can be 10 times or more longer than the service life of discharge lamps and incandescent lamps. Laser heating is significantly less than that of a discharge lamp. The light source does not need mercury. In the final spectrum there are no traces of the initial laser radiation, the efficiency is close to the maximum theoretically possible due to the properties of a completely black body.
Таким образом, задача изобретения и технические результаты достигаются. Thus, the objective of the invention and technical results are achieved.
