Abstract: The lighting device mainly contains an upper casing, an intermediate casing, a circuit board, and a lower casing. The intermediate casing has a cylindrical body with threads around a top end and a bottom end for joining with the upper and the lower casings, respectively. A spherical concave is provided in the center on the top side of the intermediate casing, surrounded by a number of LEDs. Inside the hollow lower casing, the circuit board is housed with appropriate wiring to the LEDs and a sensor assembly. The lower casing further has electrical contract means on a bottom side for introducing electricity. The spherical sensor assembly is rotatably placed in the spherical concave on the top side of the intermediate casing.

Abstract: The present invention is a lighting device having detection function, of which the structure features combination of illuminating elements and an infrared detector and a detector shade cover is used as an upper cover for the whole structure of the lighting device to thereby enhance the detection angular range of the infrared detector, simplify the manufacturing process, and providing a uniform and soft lighting source or a bright lighting source. The infrared detector has a function of detecting thermal radiation so that by detecting the thermal radiation from a human body, a signal for supplying power to the illuminating element is provided. When the infrared detector no long detects the thermal radiation from the human body, the control board stops the electric power supplied to the illuminating elements. As such, effective saving of energy can be realized.

Abstract: A bulb adapted with an infrared sensor includes a LED and a power switch, the switch being turned on to light the LED in the bulb when the sensor detects the heat emitted from a human body and turned off to kill the light when failing to detect the heat for practical use and energy saving purposes.

Abstract: A warning triangle mainly contains a stationary side piece, two movable side pieces, a stationary support piece, a movable support piece, a battery chamber, circuit boards, and light emitting diodes (LEDs) to achieve superior visibility. Grooves are provided on the two sides and along the outer edges of the side pieces, and a circuit board with distributed LEDs is positioned inside each of the grooves and driven by the battery chamber.
