Abstract:
A rotatable light-emitting diode (LED) arrangement for emitting infrared to be detected by a detector, the rotatable LED arrangement comprising:an LED member having a LED main body capable of emitting infrared light;a retaining housing defining a chamber for retaining the LED main body of the LED member therein; anda positioning base forming a front face, a rear face and an opening extending between the front face and the rear face for positioning and allowing the retaining housing to rotate therein;wherein the retaining housing is rotatably retained to the positioning base and extends forward beyond the front face of the positioning base, thereby enabling the LED member to emit infrared lights forming a conical infrared covering zone which can follow tracks of the detector by properly rotating the LED member.
