Abstract: A light reflective cover includes a concave main reflective surface and a ridge having a connecting surface, a ridge-top reflective surface, a light source end, and a light emitting end. The light source end and the light emitting end are opposite to each other. The connecting surface is opposite to the ridge-top reflective surface and connected to the main reflective surface. The ridge-top reflective surface extends between the light source end and the light emitting end. The ridge-top reflective surface includes a step for dividing the ridge-top reflective surface into a first part near the light source end and a second part near the light emitting end. The second part recesses with respect to the first part toward the connecting surface. The endpoint of the second part at the light emitting end does not protrude beyond an extension line along a first arc formed by the first part.

Abstract: A light reflective cover in the present invention includes a main reflective surface and a ridge. The main reflective surface is a concave surface. The ridge protrudes from the main reflective surface. The ridge has a light source end and a light emitting end that are opposite to each other, and a ridge-top reflective surface extending between the light source end and the light emitting end. The ridge-top reflective surface includes a first part near the light source end and a second part near the light emitting end. The ridge-top reflective surface has a step between the first part and the second part. An illumination apparatus includes the light reflective cover and a light source. The light source is disposed at one side of the light reflective cover having the main reflective surface and the ridge.
