One side of the LED illumination module (1) is connected to a side of the reflector (5). An illuminating surface of an LED faces the reflector (5). An illumination center of the LED is allowed to be arranged vertically upwards, or be provided with an angle to the direction going vertically upwards. The cross section of the reflector (5) in the vertical direction is divided into a dual-section (5a and 5b) or a tri-section (5a, 5b, and 5c) combination by a straight line, a convex surface arc, and a concave surface arc. The reflective LED lighting looses trace amounts of light, thus expanding the irradiation range in space for the light.
