PROBLEM TO BE SOLVED: To provide a control method for an LED sensor lighting device.SOLUTION: The present invention provides an LED sensor lighting device, which senses and probes an exterior object and has a first lighting mode. The LED sensor lighting device is set to the first lighting mode to sense presence or absence of an exterior object. When the LED sensor lighting device senses the exterior object, the emission luminance becomes 100% with a full-light state; when the LED sensor lighting device does not sense the exterior object, the emission luminance becomes equal to or less than 30% with a faint-light state. This enables the LED sensor lighting device to provide an energy-saving mode with faint light even in an unmanned state and thereby to avoid full darkness or the formation of a dead angle of lighting within a predetermined lighting area. Therefore, a user or pedestrian in an adjacent area can clearly sense a state ahead of him/her, which effectively improves the safety of the user or passer-by. |
