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.
