Abstract: The present invention relates to illuminating techniques, and provides an LED lamp includes a lamp body, an LED lath inside the lamp body, plug modules disposed at both ends of the lamp body, and driving powers electrically connected the LED lath with the plug modules. The lamp body includes a heat dissipating cover and a light-transmissive cover which are connected with each other. The LED lath includes a lath and a plurality of LEDs disposed along the length direction of lath. The end LEDs disposed at the both ends of the lath have light-emitting surfaces which are inclined and irradiated to the driving power. For the LED lamp provided in the present invention, each end LED disposed at the end of the lath has an inclined light-emitting surface. Accordingly, the light emitting from the end LEDs at the both ends could irradiate to the driving powers at the both ends, and thus avoiding the shadow of LED lamp, and improving the emitting effect.
