The lamp includes an electronic oscillator supplied by a current source and connected to a first coil (2) which induces a current in a second coil (3). The second coil is connected to a bulb (5) which generates a light beam (10). The second coil can easily rotate thus enabling orientation of the light beam at various angles. It can also slide along a longitudinal direction enabling adjustment of the light intensity. |
