A lighthouse lantern comprising a power supply and a phosphor-containing emitter is disclosed. The lighthouse lantern includes a power supply; a laser diode configured for receiving power from the power supply and irradiating laser in one direction; a phosphor-containing emitter positioned on a traveling line of the laser, wherein the emitter is configured for receiving the laser and emitting light; and a pair of reflective structures disposed symmetrically with respect to the phosphor-containing emitter, wherein each reflective structure has a reflective surface inclined in a direction away from the phosphor-containing emitter, wherein the reflective surfaces of the reflective structures are symmetrical with each other with respect to the phosphor-containing emitter. In accordance with the present disclosure, the lighthouse lantern may generate high output with low input power and thus has improved power efficiency, may suppress frequent failures near sea or seawater, and may reduce production costs.
