Abstract: A lighting apparatus includes a substrate, a light-emitting element, and a sealing member. The light-emitting element emits light in a first wavelength range. The sealing member contains a material that converts the light in the first wavelength range to light in a second wavelength range different from the first wavelength range. The sealing member has a curved convex contour in at least one cross section that passes through the center of the light-emitting element and is perpendicular to a principal surface of the substrate. A curved line indicating a change in output angle that occurs upon a change in observation angle is approximated by a quadratic or trigonometric function that passes through the origin.

Abstract: A light-emitting apparatus includes a first relay line and a second relay line. The first and second relay lines are disposed between a first region and a second region of a substrate. Further, the first and second relay lines extend at least partially parallel to each other in a second direction that crosses a first direction in which the first region and the second region are aligned. The first relay line electrically connects a first light-emitting element group disposed in the first region and a third light-emitting element group disposed in the second region. The second relay line electrically connects a second light-emitting element group disposed in the first region and a fourth light-emitting element group disposed in the second region.

Abstract: A light-emitting device includes a light emission controller which causes first and second light-emitting element groups to emit light, by supplying undulating voltage to the first and second light-emitting element groups. The light emission controller supplies the undulating voltage to the first light-emitting element group, during a first period in which a magnitude of the undulating voltage is greater than a first predetermined value and at most a second predetermined value. The second predetermined value is less than a maximum value of the undulating voltage. The light emission controller supplies the undulating voltage to the first and second light-emitting element groups during a second period in which the magnitude of the undulating voltage is greater than the second predetermined value. The first light-emitting element group surrounds the second light-emitting element group.
