Illuminator controlled with touchless sensor
First Claim
1. An illuminator comprising:
- a light source;
a touchless sensor for non-contact detection of approach or movement of a detection target in a range of a detection distance;
a control unit for an ON/OFF control of the light source based on an output from the touchless sensor; and
an enabling unit connected to the control unit,wherein the control unit includes a data memory for storage of threshold value that defines the detection distance, and reflected-light intensity information regarding a reflected light coming from the detection target to the touchless sensor,the control unit has a normal mode and an adjustment mode, the control unit performs the ON/OFF control in the normal mode, and the control unit adjusts in the adjustment mode the threshold value stored in the data memory, andthe enabling unit switches the normal mode and the adjustment mode.

Abstract
An LED lamp includes LED chips, a translucent cover housing the LED chips, a motion sensor unit, a condensing lens, and a power unit. The motion sensor unit includes a light receiving element for light of a predetermined wavelength. The lens condenses light of the predetermined wavelength onto the light receiving element. The power unit controls the state of operation of the LED chips based on an output from the motion sensor unit. The motion sensor unit includes a light shielding member disposed to overlap the light receiving element in an optical axis direction of the condensing lens and also to surround the light receiving element as viewed in the optical axis direction. The light shielding member is made of a material having a lower light transmissivity than that of the condensing lens for a range of wavelengths including the predetermined wavelength.
