The present disclosure relates to a lighting technology device, comprising a controller, a memory functionally connected to the controller, and an NFC antenna integrated in a casing or arranged on a board carrying the controller and the memory, wherein the antenna comprises two planar antenna wing elements arranged at an angle between 80° and 100°, preferably 85° to 95° with respect to each other, and wherein the controller is configured to process NFC data received from the antenna and store in said memory said data for programming the lighting technology device.

A lighting apparatus includes a main module and an extended module. The main module includes a power circuit, a light source, a first network interface and a controller. The power circuit is controlled by the controller to generate a driving current supplied to the light source by converting an external power source. The extended module includes a function circuit and a second network interface. The function circuit communicates with the controller via the second network interface and the first network interface to add an extended function for the controller to enhance controlling of the light source. When the extended module is detachable from the main module, the main module is operated independently without the extended function.

A vehicle lighting control method includes that a roadside communications device sends a first message to a vehicle. The first message prompts the vehicle to illuminate a first target, and the first target is near a travel path that the vehicle is to pass through. Before passing the first target, the vehicle adjusts the vehicle into a first lighting mode in advance based on the first message to illuminate the first target.

A load control system may comprise an electrical load control device and/or a computing device. The electrical load control device may control, for example, motorized window treatments (e.g., shades), lighting controls, and/or sensors (e.g., occupancy, radio window, daylight, etc.). For example, a load control device comprising a motorized window treatment may control the position of a covering material in the window treatment. The computing device may comprise a processor and/or a graphical user interface (GUI). The computing device may be a server and/or a user device, such as a wireless user device (e.g., a cellular phone, tablet, or laptop computer). The computing device may be configured to provide graphical representations that may be displayed on a GUI based on load control information.

A grow light includes a plurality of cool white LEDs, a plurality of warm white LEDs, and a driver electrically coupled to the cool white LEDs and the warm white LEDs. An intensity level and spectral composition of the radiant energy emitted by the grow light may be tuned or configured by varying a ratio of the quantity of cool white LEDs to the quantity of warm white LEDs, by varying a spatial arrangement among the cool white LEDs and the warm white LEDs, or by varying a level of current provided to some or all of the cool white LEDs and the warm white LEDs.

A mounting frame may be configured as a self-adjusting mounting frame that biases itself against a surface of structure. The mounting frame may be a component, for example, of a remote control device or a faceplate assembly. The mounting frame may be configured to bias a rear surface of the mounting frame against the surface of a structure. The mounting frame may include biasing members. Each biasing member may include an attachment portion and a pair of resilient spring arms that suspend the attachment portion relative to a perimeter wall of the mounting frame such that the attachment portion is spaced further from the rear surface of the mounting frame than locations where the spring arms extend from the mounting frame. The rear surface of the mounting frame may be defined by the perimeter wall.

Remote control devices may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be mounted over a mechanical switch that is installed in a wallbox. The remote control device may include a base, a battery, a battery holder, and a control unit. The base may be configured to attach the remote control device to the mechanical switch. The control unit may be configured to be removably attached to the base. The battery holder may be configured to retain the battery therein. The battery holder may be configured to be installed within the void defined by the housing. The battery holder may be operable between a first position in a lower portion of the void and a second position in an upper portion of the void.
