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

WIPO Patent Application WO/2013/089354

A1

The present invention relates to a reflector having a reflection pattern for compensating lighting characteristics of an LED package and an LED lamp including the same, and more specifically, to a reflector and an LED lamp formed by including the same, and the reflector is a body having an inner wall with a narrow bottom and a wide top such that the reflector is used by being matched and coupled with a chip-type LED package, wherein the reflector has, on the inner wall, a trigonometric function-type cross-wave pattern unit which is patterned to allow sine waves having curves, such as hills and valleys, to be arranged by crossing in a horizontal direction and a vertical direction at predetermined intervals over the whole area, and thus imperfect lighting characteristics of the LED package itself can be compensated by mounting a discontinuous chip whereby lighting efficiency of an LED is improved and a product can be produced at low costs, and particularly, yellow patterns or dark portions or hot spots and the like, which could not be removed from conventional LED lamps, can be removed.
