摘要： The present disclosure provides methods for generating tunable white light with controllable circadian energy performance. The methods use a plurality of LED strings to generate light with color points that fall within blue, yellow/green, red, and cyan color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output. Different light emitting modes can be selected that utilize different combinations of the plurality of LED strings in order to tune the generated white light.

摘要： According to at least one aspect, a lighting system is provided. The lighting system comprises a strip lighting device including a circuit board, a light emitting diode (LED) mounted to the circuit board, a lens disposed over the LED and configured to receive the light emitted from the LED and change at least one characteristic of the light received from the LED, and an elastomer encapsulating at least part of the circuit board. The lighting system further comprises a fixture configured to receive the strip lighting device and mount to a structure and a lighting accessory configured to removably couple to the fixture over the strip lighting device and change at least one characteristic of the light from the strip lighting device.

摘要： Composite interface circuit including bidirectional single-conductor bus, first switching circuit, and second switching circuit. Bidirectional single-conductor bus is coupled by first pull-up resistor (R1) with first direct current (“DC”) input current source having first voltage (V1). First switching circuit includes first transistor (T1) being coupled with first pull-up resistor (R1) and with bidirectional single-conductor bus. Second switching circuit includes second transistor (T2) being coupled by second pull-up resistor (R2) with second DC input current source having second voltage (V2). Second switching circuit further includes voltage divider coupling second transistor (T2) with bidirectional single-conductor bus. First and second switching circuits are respectfully configured for being coupled with first transmitter conductor (Tx1) and first receiver conductor (Rx1) of full duplex universal asynchronous data communication interface.

摘要： A method of improving high-current density efficiency of an LED, said method comprising: (a) preparing a series of LEDs having decreasing defect densities, wherein each LED of said series has a peak IQE of at least 50%, and wherein each LED of said series has the same epitaxial structure; (b) determining an increase in IQEs at high-current density between at least two LEDs of said series; (c) preparing at least an additional LED of said series by reducing defect density relative to the previously obtained lowest defect density; and (d) reiterating steps (b) and (c) until said increase is at least 3% between two LEDs of said series having a decrease X in defect densities.
