Stamp collector's inspection lamp - has UV and normal bulbs in trough-shaped shade carrying selector switch

摘要

The lamps is particularly for use by stamp-collectors. It has an opaque shade and reflector containing the ultra-violet ray bulb (3) and a normal one (4), together with a selector switch allowing either to be used. The shade is mounted on a low-height support (2), the two being so secured together that they can be separated, assembled and the angle adjusted as desired. The shade can be in the form of a trough facing downwards and fitting over the two bulbs which are supplied via a selector switch having an "off" position. The shade is fixed to the support merely by squeezing one of its edges.
