The invention relates to a swing type lighting device. The swing type lighting device comprises a power supply assembly, a lighting assembly, a positioning assembly for rotatably connecting the power supply assembly with the lighting assembly, and a flexible conductor wire for electrically connecting the lighting assembly with the power supply assembly; the swing type lighting device further comprises a connecting rod assembly for adjusting the lighting assembly to rotate around the positioning assembly; the connecting rod assembly comprises a motor, a worm, a worm wheel, a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, wherein the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod form a four-bar mechanism. According to the invention, the four-bar mechanism is driven by the motor to move; the first connecting rod moves to drive lighting components to relatively rotate around the positioning assembly, so that the lighting assembly can rotate within a range of 0 degree to 60 degrees to achieve an extensive irradiation area; and simultaneously, the manual operation is avoided; and the swing type lighting device can be used for intermittent lighting at a special region for monitoring the region, is convenient to use and capable of continuously rotating.
