Abstract: The LED module includes: a light diffusing substrate having light transmissive properties; an LED chip bonded to a first surface of the light diffusing substrate with a transparent first bond in between; a color converter facing the first surface to cover the LED chip; and a mounting substrate. The color converter is made of transparent material containing phosphor which, when excited by light emitted from the LED chip, emits light having a different color from the LED chip. The mounting substrate includes a diffuse reflection layer diffusely reflecting light emitted from the LED chip and light emitted from the phosphor. The diffuse reflection layer is placed facing a second surface of the light diffusing substrate.

Abstract: A lighting apparatus includes: a projection lens; a light source behind the projection lens; a reflector that reflects light from the light source toward the projection lens; and a shield that blocks a portion of the light reflected by the reflector to form a cutoff line in a distribution pattern of the light. A textured section demarcated by unit regions is formed on a surface of the projection lens, and when a region in a center of the projection lens is defined as a central region, and regions left and right of the central region are defined as left and right regions, respectively, in a front view, a proportion of the unit regions in the central region is greater than a proportion of the unit regions in each of the left region and the right region.
