<p>The revolving lamps allow uniform intensity of irradiation. Only 4-6 emitters are needed to irradiate a surface for which 6, 9 or more emitters were required up till now, thus providing saving in current consumption. Also, the lower number of lamps and emitters and the small dimensions of the apparatus have an advantageous effect on the production costs. In an example, the lamps are rigidly connected to a threaded tube extending through a ball joint which is retained by two bearings bushes and bolted to the housing (D). The angle rod assembly (F) is movably attached to a cylindrical body (E) which is screwed onto the threaded tube. The gear motor (G) has an eccentric roller pin which engages in the push rod of the angle rod assembly.</p> |
