Description

Осветительное устройство  Lighting device
'Область техники '' Technical field
Изобретение относится к светотехнике и может быть использовано при изготовлении светотехнического оборудования для общего наружного, внутреннего и специального освещения.  The invention relates to lighting engineering and can be used in the manufacture of lighting equipment for general outdoor, indoor and special lighting.
'Уровень техники 'Prior art
Светодиоды, являются эффективным источником света, обладают низким потреблением электроэнергии и большим сроком службы. Светодиоды имеют высокую яркость при малых угловых размерах. Использование светодиодов в качестве источников света без специальных мер защиты от световых бликов приводит к значительным зрительным нагрузкам, вызывающим ощущение дискомфорта и подсознательное желания выйти из области действия таких осветительных устройств.  LEDs are an effective light source, have low power consumption and long life. LEDs have high brightness with small angular dimensions. The use of LEDs as light sources without special measures of protection against light glare leads to significant visual stresses, causing discomfort and a subconscious desire to move out of the scope of such lighting devices.
Во многих странах введен специальный показатель ослепленности, нормирующий допустимую степень воздействия на зрение человека ярких источников света. Наиболее часто эта проблема решается путем рассеяния светового потока от источника излучения с помощью различных средств, чаще всего сочетающих в себе как защитно-декоративные функции, так и функции рассевания света. Другим путем решения указанной проблемы является распределение первичного излучения по обширной поверхности, яркость которой не будет вызывать дискомфорта и будет достаточной для создания нормируемого уровня освещенности. In many countries, a special indicator of blindness has been introduced, which normalizes the permissible degree of exposure to human vision of bright light sources. Most often this problem is solved by scattering the light flux from the radiation source using various means, most often combining both protective and decorative functions, and light scattering functions. Another way to solve this problem is to distribute the primary radiation over a vast surface, the brightness of which will not be cause discomfort and will be sufficient to create a standardized level of illumination.
С другой стороны, процесс преобразования светодиодами электрической энергии в световое излучение сопровождается выделением тепла . При этом стабильность яркости светодиодов заметно зависит от температуры кристалла светодиода . При повышении температуры квантовая эффективность кристалла уменьшается. Проблема создания термодинамического равновесия, становится тем важнее, чем более мощный световой поток необходимо получить для создания нормируемой освещенности. Особенно актуальной эта проблема становится при использовании светодиодов в оборудовании, предназначенном для создания общего освещения.  On the other hand, the process of conversion of electric energy by light emitting diodes into light radiation is accompanied by heat generation. In this case, the stability of the brightness of the LEDs significantly depends on the temperature of the LED crystal. With increasing temperature, the quantum efficiency of the crystal decreases. The problem of creating thermodynamic equilibrium becomes all the more important the more powerful luminous flux you need to get to create a normalized illumination. This problem becomes especially relevant when using LEDs in equipment designed to create general lighting.
