Abstract: Provided is an alternating current direct lighting device capable of a dimming control, the lighting device including: a circuit board having a light emitting diode array; a first connector disposed on the circuit board; a second connector disposed on the circuit board so as to be spaced apart from the first connector; and a driving unit for controlling light emission of the light emitting diode array on the basis of a driving signal input through the first connector and a dimming signal input through the second connector.

Abstract: A lighting device includes: a circuit board; a first light emitting diode array and a second light emitting diode array; and a driving circuit. The first light emitting diode array and the second light emitting diode array are mounted on the circuit board so as to generate light, the first light emitting diode array is disposed on the circuit board, and the second light emitting diode array is disposed on the circuit board apart from the first light emitting diode array. The driving circuit is mounted on the circuit board so as to generate an electrical signal for driving the first light emitting diode array and the second light emitting diode array, and the driving circuit is disposed between the first light emitting diode array and the second light emitting diode array.

Abstract: Disclosed is a drone station which allows the center of resonance of a drone to be always accurately aligned regardless of the initial landing position of the drone. The disclosed drone station includes a landing guidance instrument and a wireless charging instrument which is formed on the landing guidance instrument and wirelessly transmits the power to a drone positioned thereon, the landing guidance instrument having an inclined surface which moves the landed drone onto the top of the wireless charging instrument.

Abstract: The present disclosure provides a lighting control device having a power supply module and a control module formed integrally. The lighting control device is installed by replacing a power supply device mounted at a conventional lighting apparatus to connect the conventional lighting apparatus to a smart lighting system. The lighting control device controls the output (i.e., current) of the power supply module according to the number of LED modules or the number of the normally operating LED modules, thereby preventing a current exceeding a driving current from being applied to the LED module.
