<p>The invention relates to the carrying out of a luminous lamp for lighting, used in the public electric energy distribution network using an arc starting/feeding system. According to the invention, the luminous lamp rapidly induces (10-2...10-1s) the low pressure in gas the mercury vapour luminous tubes, without using the filament pre-heating circuit of the electrodes, by means of an electronic device, serially connected in the luminous tube supply circuit, comprising some diodes (D1, D2, D3 and D4), connected in rectifier bridge mounting, and parallelly to these diodes (D1, D2 or D3, D4) there are connected two condensers (C1 and C2) which form two branches adjacent to one of the alternating current entering kinks. At the same time, it controlls the electronic current, without energy losses, by using a stable-luminous tube (TSF) - supplementarily built by a grid electrode, mounted inside the active cavity (CA), and connected in the lamp circuit, by means of an adjustable resistive divider, so that it performs the radiant luminous flux adjusting function.</p> |
