An exemplary LED lamp includes a housing having an opening, a printed circuit board, at least one LED, a light reflective element, at least one light-shielding sheet and a lamp cover. The printed circuit board is positioned on a bottom of the housing. The LED is electrically connected with the printed circuit board. The light reflective element defines at least one through hole, the LED passing through the corresponding through hole. The at least one light-shielding sheet corresponds to the at least one LED respectively. Each light-shielding sheet comprises a bottom reflective plate and a pair of opposite sidewalls extending from two opposite ends of the bottom reflective plate. A plurality of light holes is defined at ends of the bottom reflective plate adjacent to the two opposite sidewalls. The lamp cover is fixed on the opening of the housing. The LED lamp assembly has a uniform luminance.
