The lighting device mainly contains an upper casing (1), a middle casing (2), a circuit board (3), a lower casing (4), and a sensor assembly (20). The middle casing (2) has threads to join the upper and lower casings. Light emitting diodes (LEDs) (21) are configured on a top side of the middle casing (2), and the sensor assembly (20) is configured among the LEDs (21). The lower casing (4) is joined to a power socket and, inside the lower casing, the circuit board is configured and connected to the LEDs (21) and the sensor assembly (20). The sensor assembly (20) contains a cylindrical casing with a spherical top end threaded through a ring, jointly constituting a substantially spherical shape. The sensor assembly (20) is then rotatably configured in a spherical concave on the top side of the middle casing, so that it could be easily turned to point to a desired coverage area by adjusting its rotational angle. |
