Abstract: A computer-implemented method is disclosed herein. The method includes the step of receiving, with a processing device of a commerce server, one or more shopping list signals from an electronic computing device to establish a shopping list of a plurality of items offered for sale in a retail store. The method also includes the step of receiving, with the processing device, one or more consumer signals from a first augmented reality device and a second augmented reality device. Each augmented reality device can be worn by a consumer as the consumer shops in the retail store. The method also includes the step of transmitting, with the processing device, a first procuring signal containing data associated with the shopping list to the first augmented reality device and a second procuring signal containing data associated with the shopping list to the second augmented reality device, such that the consumers can cooperatively shop for items on the shopping list.

Abstract: An LED circuit includes a series of LED devices, a power supply circuit and a signal control circuit. Each of the LED devices includes an LED unit and an integrated circuit unit having a specific serial number and receiving an electrical parameter. The signal control circuit is coupled to the power supply circuit and the series of LED devices, and has a loaded status. The signal control circuit changes the loaded status in response to a control signal so as to cause the electrical parameter to have a variation, the variation of the electrical parameter generates a signal code having an information, all the integrated circuit units receive the signal code, and a specific LED unit will be driven by a corresponding integrated circuit unit when the signal code corresponds to the specific serial number of the corresponding integrated circuit unit.

Abstract: An LED array includes three or more strings of bare LEDs mounted in close proximity to each other on a substrate. The strings of LEDs emit light of one or more wavelengths of blue, indigo and/or violet light, with peak wavelengths that are less than 490 nm. Luminescent materials deposited on each of the LED chips in the array emit light of different wavelength ranges that are of longer wavelengths than and in response to light emissions from the LED chips. A control circuit applies currents to the strings of LEDs, causing the LEDs in the strings to emit light, which causes the luminescent materials to emit light. A user interface enables users to control the currents applied by the control circuit to the strings of LEDs to achieve a Correlated Color Temperature (CCT) value and hue that are desired by users, with CIE chromaticity coordinates that lie on, or near to the black body radiation curve.

Abstract: An LED bulb comprises a structural shell formed by folding a flat PCB into a three-dimensional polyhedron shape and a fitting for removably coupling the bulb to a light socket. The PCB comprises a plurality of LEDs, at least one LED mounted electronically on a plurality of faces of the polyhedron, and a driver circuit for driving each LED. The perimeter of the PCB is shaped to join adjacent faces. Each LED produces minimal excess heat, which is partially conducted by a metallic heat sink bridge to the PCB and dissipated to the air through the PCB and through a plurality of spaces in the shell.
