Abstract: An end cap for a solid-state lighting device is described that provides an electrical connection(s) between an external power source and at least one solid-state emitter disposed in a hollow member of the lighting device. An outer wall extends a first distance and an inner wall extends a second distance from an inward-facing side of the end cap base. A gap between the inner wall and the outer wall accommodates the insertion of the hollow member. A contactor electrically coupled to a conductive member on an opposite side of the end cap extends into the gap. The contactor exerts a force on a flexible conductor and provides a power supply path to or power return path from the at least one solid-state emitter. Preferably, the lighting device includes an array of solid-state emitters disposed on a flexible substrate.

Abstract: In general, one embodiment of the present disclosure includes a horticulture lighting device having a plurality of LED light channels that may be selectively energized to produce a predefined light pattern. Each of the LED light channels may emit one or more wavelengths and may be pulsed at a rate that may be imperceivable to a human eye, e.g., at 120 Hz to 720 Hz. Plants may respond biochemically to light patterns that include a period of delay between pulses of light, e.g., from 500 microseconds to 5 milliseconds. The biochemical response has been shown to significantly increase plant growth, e.g., up to 100%, relative to plants grown with lighting systems that use continuous, non-pulsing light sources. Thus, aspects and embodiments disclosed herein include a horticulture device capable of emitting light patterns which introduce a predefined delay period between energizing/pulsing of LED light channels to aid photosynthesis.

Abstract: A system and method for resolving the angle of the transmitter and the angle of the receiver when determining vehicle position using light based communication (LBC) signals. Each vehicle includes an LBC system having light emitting diodes (LEDs) and receiver photodiodes capable of sending and receiving pulsed light binary messages. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes.

The angle of the receiver may be determined using a single digital message received at a first receiver and a second receiver on a receiving vehicle. The angle of the transmitter may be determined using a first digital message and a second digital message received at a same receiver on the receiving vehicle.
