The disclosed reflective LED lighting device (10), which can shine with a high lighting intensity and at a wide angle, is characterized by: two reflective LED packages (1A, 1B) being prepared-which are each provided with: a support body (6) that opens upwards and that has a parabolic reflective surface (2) inside, of which the direction of outgoing light faces upwards; and two LED chips (11, 12) that are supported by leads at the upper center of the reflective surface of the support body in a manner so as to be adjacent along one axis, which is the x-axis direction, and in a manner so as to emit light towards said reflective surface-wherein the two LED chips are positioned closer to said reflective surface than the focal point (F) of the parabolic surface of the reflective surface (2), and the vertical line extending from the center (C) of the parabolic surface of the reflective surface to a line in the x-axis direction, which links the centers of the light-emitting sections of the two LED chips, are given a positional relationship of being offset by a predetermined angle (?) with respect to the y-axis direction, which is the direction normal to the light-emitting surfaces of the two LED chips; and the two reflective LED packages being aligned in the y-axis direction in a positional relationship of being offset in opposite directions with respect to each other by the predetermined angle (?). |
