An exemplary light tunnel includes at least three reflectors arranged one adjoining the other in sequence, thereby forming a corresponding at least three-sided enclosed conduit structure. At each of a plurality of junctions where a first adjoining reflector and a second adjoining reflector adjoin each other, an end portion of the first adjoining reflector abuts an end face of the second adjoining reflector and extends beyond an outer surface of the second adjoining reflector. The two adjoining reflectors are joined to each other by adhesive. The adhesive extends between a extending part of the end portion of the first adjoining reflectors that extends beyond the outer surface of the second adjoining reflector and a part of the outer surface of the second adjoining reflector.
