Abstract: A projection lamp includes a bulb, a main reflective cover and a secondary reflective cover. The bulb includes a wick and a lamp tube which wraps the wick. The wick is configured to emit divergent light beams while the bulb is lit up. The main reflective cover is connected to the lamp tube and includes a main reflective surface facing the wick. The main reflective surface is configured to convert the divergent light beams into projection beams. The secondary reflective cover is melt bonded to the lamp tube and includes a secondary reflective surface facing both of the wick and the main reflective surface. The secondary reflective surface is configured to reflect a portion of the divergent light beams, cannot be directly emitted onto the main reflective surface, onto the main reflective surface while the bulb is lit up.
