Downlight with illumination angle adjustable polydirectionally

摘要

A downlight includes: an outer cover; a heatsink; and a light engine located between the outer cover and the heatsink, wherein the light engine is at least partially spherical; the heatsink has a hemispherical inner surface that matches with the spherical portion of the light engine; the outer cover and the heatsink are assembled together by an elastic extension member, thereby making the hemispherical inner surface of the heatsink in contact with the spherical portion of the light engine; the downlight includes a pin provided near the elastic extension member, with one end of the pin fixed to the heatsink and the other end extending through the outer cover. Pressing the end of the pin that extends through the outer cover, the elastic extension member is further extended to separate the heatsink and the light engine so that the illumination angle of the light engine can be adjusted.

1. A downlight, comprising:
an outer cover; a heatsink; and a light engine located between said outer cover and said heatsink, wherein said light engine is at least partially spherical and comprises:
a housing having a spherical contour and an opening and a LED light source provided inside said housing; said heatsink disposed outside said housing and having a hemispherical inner surface that matches with a spherical portion of said housing; said outer cover and said heatsink are assembled together by at least one elastic extension member, thereby making the hemispherical inner surface of said heatsink in contact with the spherical portion of said housing; said downlight further comprising at least one pin provided in the vicinity of said elastic extension member, with one end of said pin fixed to said heatsink and the other end thereof extending through said outer cover, and by pressing the end of the pin that extends through said outer cover, said elastic extension member is further extended to separate said heatsink and said light engine so that the illumination angle of said light engine can be adjusted.
