Light source for white color LED lighting and white color LED lighting device

A white LED lighting device comprising:

• a lamp body including a mounting base, a lamp casing, a colorless transparent globe fixed to an opening in a bottom of said lamp casing, a light source for emitting white LED lighting and housed in said lamp casing, and a light source controller housed in said lamp casing, said lamp casing and said globe each having a rectangular rear portion at said mounting base, sidewalls of said rear portion being parallel to a longitudinal axis of said lamp body, and each of said lamp casing and said globe having an elongated trapezoidal front portion adjacent to said rear portion, said globe having an illumination portion, said illumination portion having a smooth inside surface and a longitudinally-banded concavo-convex outside surface with alternating adjoining ridges and valleys, said illumination portion of said globe having a curved shape symmetrical with respect to a longitudinal center line;
• a lamp support for supporting said lamp body such that an illuminating surface of said lamp body is directed downward and so that a longitudinal axis of said lamp body extends forwards with a slight upward tilt;
• and
• a power source device housed in a lower part of said lamp support for supplying electric power to said light source for emitting white LED lighting;
• wherein said light source for emitting white LED lighting includes:
• a reflective plate having a plurality of holding holes arranged in a multi-row, multi-column array with a prescribed pitch;
• a plurality of white LED elements held within said holding holes of said reflective plate, said plurality of LED elements held such that a front surface of said reflective plate is located 2 mm to 4 mm behind an electrode portion of each of said LED elements, each of said LED elements having a positive terminal and a negative terminal;
• a base plate attached to said positive terminal and said negative terminal of each of said LED elements, said base plate being arranged parallel to and directly behind said reflective plate;
• and
• a series-parallel electrical network connected to said positive terminal and said negative terminal of each of said LED elements;
• wherein sections of said reflective plate and said base plate located in said rear portion of said lamp casing and said globe have a half-angled gutter shape corresponding to said curved illumination portion of said globe;
• and
• wherein sections of said reflective plate and said base plate located in said front portion of said lamp casing and said globe have an elongated trapezoidal flat shape corresponding to said curved illumination portion of said globe.

A light source for emitting white LED lighting, comprising:

• a reflective plate having a plurality of holding holes arranged in a matrix-type array with a prescribed pitch;
• a plurality of white LED elements held within said holding holes of said reflective plate, said plurality of LED elements held such that a front surface of said reflective plate is located 2 mm to 4 mm behind an electrode portion of each of said LED elements, each of said LED elements having a positive terminal and a negative terminal;
• a base plate attached to said positive terminal and said negative terminal of each of said LED elements, said base plate being arranged parallel to and directly behind said reflective plate;
• and
• a series-parallel electrical network connected to said positive terminal and said negative terminal of each of said LED elements.
