Description
(54) ОСВЕТИТЕЛЬНОЕ УСТРОЙСТВО(54) LIGHTING DEVICE
II
Изобретение относитс к устройствам дл питани газоразр дных источников света и может быть использовано в промышленности , производ щей и эксплуатирующей осветительные у-стройства, а также дл общего и местного освещени производственных , общественных и бытовых объектов, где требуетс минимальна пульсаци светового потока.The invention relates to devices for powering gas-discharge light sources and can be used in the industry producing and operating lighting fixtures, as well as for general and local lighting of industrial, public and domestic objects where minimal pulsation of the light flux is required.
Известны осветительные устройства, в которых питание двух последовательно соединенных газоразр дных ламп или одной газоразр дной лампы, имеющей два последовательно расположенных разр дных промежутка , осуществл етс от трехпроводной трехфазной сети через три разных по величине индуктивных балластных элементов I.Lighting devices are known in which two series-connected gas discharge lamps or one gas discharge lamp having two consecutive discharge gaps are powered from a three-wire three-phase network through three differently sized inductive ballast elements I.
Названные устройства непригодны дл питани ламп от двух фаз и нулевого пров да трехфазной сети.These devices are unsuitable for powering the lamps from two phases and the ground wire of a three-phase network.
Известно также осветительное устройство с газоразр дными лампами, в котором питание двух ламп осуществл етс от двух фаз и нулевого провода четырехпроводной трехфазной сети через два индуктивных балластных элемента, последовательно с каждым из которых между одной из разных фаз сети и нулевым проводом включена одна из ламп 2.It is also known a lighting device with gas-discharge lamps, in which two lamps are powered from two phases and a neutral wire of a four-wire three-phase network through two inductive ballast elements, in series with each of which one of the lamps is connected between one of the different phases of the network and the neutral wire. .
Однако это устройство не позвол ет получить достаточно низкий уровень пульсации светового потока ламп.However, this device does not allow to obtain a sufficiently low level of pulsation of the luminous flux of the lamps.
Цель изобретени - уменьшение пу-тьсации светового потока ламп.The purpose of the invention is to reduce the pu-light of the luminous flux of the lamps.
