Stand lamp for interior lighting with variable radiation characteristic enables radiation characteristic to be altered with a simple arrangement

摘要

The stand lamp has a lamp foot (1) and a frame (2) defining the longitudinal axis and carrying two reflectors associated with one or more lamps. The positions of at least the first and/or the second reflector is variable so that, related to a section parallel to the lamp's longitudinal axis, full light distribution is produced in a first angular region for a first position of the reflectors. In a second position full light distribution is produced in a second, larger angular region. The light from the first reflector and direct from the lamp overlaps the light from the second reflector in both positions, the degree of overlap being greater in the second position
