Patent attributes
An infrared-sensitive lighting device includes a host, a light-emitting module and an infrared sensing module. The light-emitting module is disposed on the host. The infrared sensing module includes a casing, a circuit board, a sensor and a lens cover. The casing is installed on the host and has an opening. The circuit board is disposed within the casing. The sensor is installed on the circuit board and aligned with the opening. The lens cover is rotatably mounted on the opening. The lens cover has a lens pattern. When the lens cover is in a first state, the sensor performs a sensing operation at a first direction angle through the lens pattern. When the lens cover is in a second state, the sensor performs the sensing operation at a second direction angle through the lens pattern.
