  • Patent number: 9523493
    Abstract: 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.
