Abstract
The present invention provides a two-level detection lighting fixture, comprising: a lighting module, comprising a primary lamp and a secondary lamp; a detection module, comprising an environment detector for detecting an ambient light level and generating a first signal, and a human motion detector for detecting human motion within a predetermined area surrounding the lighting module and generating a second signal; and a control module for controlling the secondary lamp of the lighting module to turn on or off, receiving the first signal and the second signal generated by the detection module, and driving the primary lamp of the lighting module to turn on by using the first signal or the second signal. Conventional motion sensing lights have a common drawback that a light is only turned on when a person passes through the surrounding area of the light. The present invention overcomes this drawback and thereby provides lighting with improved security.
