The invention relates to an LED Chinese knot landscape lamp which comprises LED light-emitting bars, a Chinese knot lamp, a Chinese knot fringe and a support. Each LED light-emitting bar is composed of a lamp slice groove, an LED paster and sealing resin. The lamp slice grooves are arranged to be bar-shaped grooves, and LED paster lamp beads and circuit boards are arranged in the groove and are poured and sealed through the resin. The Chinese knot lamp is composed of two semi-light-transmittance red Chinese knot lamp shells and an LED light-emitting bar connecting plate. When a power source is switched on, the front faces and the back faces of the whole Chinese knot lamp shells are lightened; according to the Chinese knot fringe, each pipe is internally connected with the several LED light-emitting bars in series, and the whole Chinese knot fringe is lightened when the power source is switched on; and the support is composed of a Chinese knot lamp connecting frame, a Chinese knob fringe bracket and a supporting rod. According to the LED Chinese knot landscape lamp, each LED light-emitting bar is independently subjected to rubber filling sealing, the sealing effect is good, water entering is not likely to happen, lamp bead feet are not likely to be oxidized, the service life is long, replacement is facilitated when problems happen, and potential safety hazards are not likely to happen.
