[0028] The utility model provides the following technical solution: a laser flash lamp 100, comprising a shell 10, the shell 10 comprising a first shell 101 and a second shell 102, the second shell 102 being rotatably connected to the first shell 101; a circuit board 20, a driving power supply 40, a laser module 60, a fluorescent sheet 70 and a lens 80 are arranged inside the shell 10, the laser module 60, the fluorescent sheet 70 and the lens 80 are located inside the second shell 102, the fluorescent sheet 70 corresponds to between the laser module 60 and the lens 80, and the scattering surface of the lens 80 is exposed to the outside of one end of the second shell 102 away from the first shell 101; the circuit board 20 is electrically connected to the driving power supply 40, the laser module 60 comprises a red laser source 601, a green laser source 602 and a blue laser source 603, and the driving power supply 40 is electrically connected to the red laser source 601, the green laser source 602 and the blue laser source 603 respectively.

When it is necessary to adjust different flash colors, the circuit board 20 can control the driving power supply 40 to power on one of the red laser source 601, the green laser source 602, and the blue laser source 603 in the laser module 60, or two of them, or three of them. Then, the red laser source 601, the green laser source 602, and the blue laser source 603 in the laser module 60 can be controlled to generate monochromatic light, two-color fusion light, or three-color fusion light, thereby adjusting the laser module 60 to produce different flash colors. When the flash brightness needs to be adjusted, the circuit board 20 controls the driving power supply 40 to simultaneously increase or simultaneously reduce the current provided by the red laser source 601, the green laser source 602, and the blue laser source 603 in the laser module 60 to the same value, thereby increasing or reducing the overall luminous power of the red laser source 601, the green laser source 602, and the blue laser source 603 in the laser module 60 as a whole, so that the brightness of the light generated by the fusion of the red laser source 601, the green laser source 602, and the blue laser source 603 in the laser module 60 can be controlled and adjusted.
