This invention concerns a lamp (1) which provides even lighting in a room according to a predetermined level of illumination. To achieve a degree of uniformity, it is necessary to bring reflection and direct illumination into a particular relationship. It is important to construct the reflector (4) so that no concentrated beam of a particular lighting component is obtained. The interplay of the dull finish surfaces within the lamp (1) results in a uniformity of g = 0.66 of the nominal luminous intensity En. |
