The utility model relates to a LED positioning lighting energy saving lamp, which comprises a circuit board, and the X direction and Y direction is regulated along the plane. A lighting unit comprises a first lighting unit positioned on the middle of circuit board and a second lighting unit correspondingly positioned on two sides of the first lighting unit. Each lighting unit comprises a plurality of LEDs in inclined installation with pipe body having a certain distance with circuit plane, and a plurality of LED for each lighting unit are arranged in array along the X direction and Y direction of the circuit board and are in symmetrical distribution along the array center. Each LED is separated a certain angle in respect to the X direction and Y direction, to make each lighting unit respectively form scheduled angle of projection on X direction and Y direction. The angle of projection for LED is smaller than 15 degrees, and the brightness is bigger than 20000 Candela. The utility model can realize correct radiation, and has good lighting effect and energy saving effect with good heat emission, which is applicable for the lighting of road surface. |
