This is light that is bounced off another object usually a wall or a ceiling or it can be part of a fitting or bulb. It comes from a directional light source usually but has the light diffused by the reflection. Rather than a spotlight shining directly on an object, the light is bounced off a wall or ceiling to subtly and/or softly illuminate rather than receive the full intensity of directional light.
Light redirected from an opaque object or surface. The amount of light reflected depends on the angle at which the light strikes the object, the smoothness of the surface, and the color of the surface.
