  • Publication number: 20210033917
    Abstract: An optical member is provided that achieves a desired light distribution characteristic with a simple configuration. The optical member extends along a first plane and has a thickness in a first direction perpendicular to the first plane. The optical member includes n-number of inclined surfaces. The n-number of inclined surfaces include first to n-th inclined surfaces. The first to n-th inclined surfaces are positioned in respective regions other than regions overlapping each other in the first direction. The first to n-th inclined surfaces are each inclined at an angle Am with respect to the first plane and allow entering light to pass therethrough. The angle Am is smaller than 90 degrees.

  • Patent number: 10133121
    Abstract: There is provided a light-emitting device that exhibits superior luminance contribution rate of a light source while reducing in-plane luminance unevenness despite a simple configuration. The light-emitting device includes: a substrate on which one or more light sources are provided; and a reflective plate placed on the substrate. The reflective plate includes: an opening into which the light source is inserted; a sloped section that is sloped relative to the substrate while surrounding the opening, and has a first thickness; and a top surface section that is coupled to a top end of the sloped section, and has a second thickness. The first thickness is greater than the second thickness.
