Abstract: A light emitting diode (LED) lamp includes a plurality of LED chips and a heat dissipation member configured to dissipate heat generated from the LED chips. The heat dissipation member includes a tubular unit having a constant cross-section perpendicular to an axial direction, and a plurality of fins, each of which extends outwardly from the tubular unit and extends in the axial direction, having a constant thickness in the axial direction.

Abstract: The illumination device disclosed in the present specification has a light source, a touchless sensor for detecting proximity and movement of an object without contact, and a control unit for controlling the driving of the light source on the basis of an output of the touchless sensor.

Abstract: An illumination device that includes a plurality of LED chips and a heat-dissipating unit including a fan configured to ventilate air. The plurality of LED chips are cooled as heat generated in the plurality of LED chips is transferred to the air ventilated by the fan.

Abstract: An LED lighting device includes a plurality of LED chips and a pair of side mounting faces. The distance between the side mounting faces becomes smaller from the base side toward the extremity side in the x direction. The side mounting faces face mutually opposite sides in the y direction. Also, the distance between the side mounting faces becomes shorter from the back side toward the front side in the z direction that is perpendicular to both the x direction and the y direction. The plurality of LED chips include LED chips mounted on the pair of side mounting faces. The LED lighting device illuminates an illumination target with a uniform illuminance distribution.
