The utility model discloses an LED (light-emitting diode) filament head lamp, which comprises a lamp cap (1), an LED power supply (2), a glass bulb (5), a glass core column (3), a plurality of LED filaments and a permanent magnet (7), wherein the lamp shape (1) is connected with the mains supply; the LED power supply (2) is arranged in the lamp cap (1); the glass core column (3) is fixedly arranged in the glass bulb (5); positive lead and negative lead (41 and 42) are embedded into the glass core column (3); the plurality of LED filaments are connected with the positive lead and negative lead (41 and 42), and are fixed on the glass core column (3) to shine; the LED filaments are divided into an anode group and a cathode group; and a power connecting terminal of the LED filaments of the anode group and the power connecting terminal of the LED filaments of the cathode group are connected in series by the permanent magnet (7) in a magnetic drawing manner. Due to active pickup connection employing the permanent magnet, the filament connection stability is ensured; meanwhile, when the LED filament head lamp works and thermally expands, the elongation part of the LED filament head lamp can freely slip and stretch, so that various filaments are pulled into a cone form to be hidden into a cone body by the permanent magnet. The top end of a conical luminous body also has luminous efficacy, so that a shadow and a weak light region are prevented from being generated in the lighting direction, so as to obtain a uniform three-dimensional lighting effect.
