| 简介 |
Useful model relates down electrical engineering and illumination engineering, in particular, to the illuminating devices on the basis of electrodeless gas-discharge tube with the ultra-high frequency (SHF) pumping when the rotation of its flask is present, and can be used for guaranteeing a maximally possible period of the service of the basic structural elements (flask of burner and magnetron) of illuminating equipment on the basis of powerful electrodeless SHF discharge. , the block of emergency turning off (13) and the indicator of emergency turning off (14) makes it possible to provide via a constant control of the number of revolutions of shaft (5) electric motor (4) observation besides changes in the temperature of flask (1), and so a constant control the temperature of magnetron (6). With any not normal modes of the work of electric motor (4) and/or overheating magnetron (6) the block of emergency turning off (13) achieves turning off of generator of high voltage (8) with the simultaneous start of the indicator of emergency turning off (14), which ensures increase in the reliability of operation and longevity of the proposed illuminating device due to the conditions for rare maintenance. 1 [n].[z].[p]. of formula, 2 illus. |
