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 device includes: a substrate; a plurality of light emitting elements mounted in a light emitting area of the substrate, and an intermediate line for electrically connecting a plurality of light emitting elements in parallel or series selectively, the intermediate line being disposed in the light emitting area.
