Abstract

Осветительное устройство с улучшенными оптическими характеристиками и повышенным КПД содержит источник энергии, источник света, отражатель и держатель. Отражатель имеет первый открытый конец, второй конец и параболический профиль между первым открытым концом и вторым концом. Фокус параболического профиля находится за пределами профиля с внешней стороны параболы. Отражатель также может быть подвижным относительно источника света. Осветительное устройство может включать в себя электрическую цепь, которая подает импульсный или термокомпенсированный импульсный ток к источнику света. Осветительное устройство также может включать в себя теплоотводящий корпус.
