Shielding for tube lamps intended for ultraviolet emission; method for reducing the harmful effect of direct irradiation

摘要

Beneath the lamp 1, partial bottom shielding 3 intersects direct emission into the surroundings, and symmetrical side screens 7 have lobes 7a which reflect downwards in inclined directions, and lobes 7b suitable for reflection upwards as an addition to direct upward emission; the downwards irradiation thus becomes non-harmful, yet effective. <IMAGE>
