<p>PROBLEM TO BE SOLVED: To recognize the execution of off control even if the operation of a load is not confirmed by arranging a sound device for informing the conduction of off control with a sound when a control part controls on and off of a load according to the detection or no detection with a heat sensitive sensor in relation to the temperature change. SOLUTION: When a heat sensitive sensor 1 detects temperature change caused by the move of a person, a control part 2 turns on a load 3 of a luminaire, and when the temperature change is not detected, the control part 2 turns off the load 3. When a user is apart from a detecting area of the thermosensitive sensor 1, since the thermosensitive sensor 1 detects the temperature change for a while, a load 3 is not off controlled soon, the user moved cannot confirm the light out of the load 3. When off control is conducted, a sound device 4 is driven, off control to the load 3 is informed by a buzzer or sound such as voice, and the user can confirm the off control even in the position far from the load 3.</p> |
