Abstract: The present invention relates to a LED directional illumination energy-saving luminaire and a manufacturing method thereof. The luminaire comprises: a plane circuit board with an X direction and a Y direction defined; and illumination units including a first illumination unit, which is arranged at the center of the circuit board, and two second illumination units arranged at the both sides of the first illumination unit symmetrically. Each illumination unit includes a plurality of LEDs mounted to said circuit board in a tilted state with said LED bodies being positioned at a predetermined height from the plane circuit board, and said plurality of LEDs are arranged at intervals In an array along said X direction and said Y direction and are symmetrically distributed with respect to the center of said array. Each LED deviates from the X direction and the Y direction at a predeterminative angle, so that the illumination units can form predeterminative project angles in the X direction and the Y direction respectively. The projection angle of the LED is less than 15 degrees and the luminous intensity thereof is higher than 20000 mod. The luminaire is capable of achieving an accurate directional illumination, has a well lighting effect and energy-saving effect, and has a well performance of heat dissipation, thus is especially suitable for the street lighting.
