  • Patent number: 11287106
    Abstract: A backlight module includes a base plate, a plurality of light-emitting elements and a plurality of lenses. The light-emitting elements are disposed on the base plate. The lenses are disposed on the base plate and respectively correspond to the light-emitting elements. Each of the lenses has a side surface and a plurality of diffusing portions. The diffusing portions are located on the side surface. At least one of the diffusing portions of each of the lenses is located between adjacent two of the corresponding lenses.

  • Patent number: 8633641
    Abstract: A side illumination lens for a LED is disclosed. One of the embodiments includes a bottom cavity, an incident surface, four total internal reflective surfaces, and a side refractive surface. Light beam emitted by the LED enters the lens through the incident surface. A first portion of the light beam is reflected by the total internal reflection surfaces to the refractive surface and emits out of the lens. The second portion of light beam enters the lens and exits from the refractive surface. A second one of the embodiments is to roughen the side refractive surface for diffusing the exit light beams so that a broader area can be illuminated softly.
