AN ILLUMINATION DIRECTION A REGULATION IS POSSIBLE LED LENS STRUCTURE SIEVE

摘要

An LED lens structure for controlling an illumination direction including a protrusion hole, a jaw, and reflection ring is provided to emit a light to one-way by collecting a light in a necessary location. An LED lens structure for controlling an illumination direction comprises the followings: a base plate(6) bonding(8) a plurality of LED chips(7) arranged in an upper side; a base ring(5) forming a screw part(13) in an outer circumference, and forming a slope capable of locating a lens(3); a lock nut(4) forming the screw part into an inner circumference; a protrusion hole formed in a upper side center of a cylindrical shape; a jaw formed in an edge of the protrusion hole; and a reflection ring(2) forming the screw part.
