WIPO Patent Application WO/2020/083260
Kind Code:
A1
Abstract:
Disclosed is an illumination lamp, comprising: a support column, comprising a top end, a bottom end, and a side wall between the top end and the bottom end; a first light source module, provided on the outer side of the side wall of the support column and comprising a substrate and a plurality of columns of first light sources provided on the substrate and arranged along a circumferential direction of the support column, each column of first light source extending in a direction from a top end to a bottom end of the support column; and a mask, covered on the outer side of the first light source module. The plurality of columns of first light sources is configured to emit light toward the mask side, and the maximum light exit surface of each column of first light source on the mask intersects at least the projection of a normal of the adjacent column of first light source on the mask. In this case, the illumination lamp can form uniform side light emission according to needs, thereby increasing the light-emitting pattern of the illumination lamp and thus better meeting usage requirements.
