REFLECTOR HAVING REFLECTION PATTERN FOR COMPENSATING FOR LIGHTING CHARACTERISTIC OF LED PACKAGE AND LED LAMP INCLUDING THE SAME

摘要

A reflector having a reflection pattern for compensating for a lighting characteristic of an LED package includes a body configured to be matched and coupled with the LED package having a discontinuous chip arrangement structure to improve the lighting characteristic of the LED package for divergent light. The body includes an inner wall having a diameter which is increased upwardly to form a narrow bottom and a wide top and including an opening formed at a lower end thereof so as to arrange the LED package therein. The inner wall of the body is formed with a trigonometric cross-wave pattern part which is patterned such that sine wave-type waves curved to form peaks and valleys are arranged to cross in a horizontal direction and a vertical direction at predetermined intervals over the whole area. The reflection pattern can compensates for an incomplete lighting characteristic of an LED package itself.

1. A reflector having a reflection pattern for compensating for a lighting characteristic of an LED package, the reflector comprising:
a body configured to be matched and coupled with the LED package having a discontinuous chip arrangement structure to improve the lighting characteristic of the LED package for divergent light, wherein the body includes an inner wall having a diameter which is increased upwardly to form a narrow bottom and a wide top and including an opening formed at a lower end thereof so as to arrange the LED package therein, and wherein the inner wall of the body is formed with a trigonometric cross-wave pattern part which is patterned such that sine wave-type waves curved to form peaks and valleys are arranged to cross in a horizontal direction and a vertical direction at predetermined intervals over the whole area.
