Document Type and Number:
WIPO Patent Application WO/2016/149900
Kind Code:
A1
Abstract:
A conical frustum shaped optical lens (110) is made of transparent material, the conical frustum shaped optical lens (110) having a long diameter at a first end and a short diameter at a second end and the conical frustum shaped optical lens (110) defined by multiple rotational surfaces (210, 220, 230, 240) and a flat fifth surface (250). The conical frustum shaped optical lens (110) is configured to create folded light paths within the conical frustum shaped optical lens (110) such that a majority of light from a light source is reflected twice within the conical frustum shaped optical lens (110) before being output. An MR16 form factor LED spotlight including the conical frustum shaped optical lens (110) can achieve a reduced light beam angle and a higher central luminous intensity.
