Abstract:
A growth system for growing vegetation is provided, and includes a plurality of modular growing units defining a vegetative zone; a plurality of lighting units including a lighting node for selectively emitting first and/or second wavelengths of light in the vegetative zone; an unpressurized reservoir for housing a fluid containing one or more nutrients; a nutrient feeding system for fluidly connecting each of the modular units to the reservoir in parallel; and a pump in fluid communication between the reservoir and the modular units. When a modular unit is connected to the respective quick connect valve, the nutrient feeding system directs the fluid to the modular unit, and when the modular unit is disconnected from the valve, the valve is configured for preventing the fluid from flowing from the reservoir through the valve, and the other modular units connected to the nutrient feeding system remain fluidly connected to the reservoir.
Abstract:
A two-level LED security light with a motion sensor. At night, the LED is turned on for a low level illumination. When the motion sensor detects any intrusion, the LED is switched from the low level illumination to a high level illumination for a short duration time. After the short duration time, the LED security light returns to the low level illumination for saving energy. The LED security light includes a power supply unit, a light sensing control unit, a motion sensing unit, a loading and power control unit, and a lighting-emitting unit. The lighting-emitting unit includes one or a plurality of LEDs which may be turned-on or turned-off according to the sensing results from the light sensing control unit. When the motion sensing unit detects an intrusion, the illumination of the LED security light can be immediately turned on to the high level to scare away the intruder.
Abstract:
An adjustable LED lighting system may allow for a variable lumen output, an estimation of remaining life expectancy, and/or control of lighting intensity, color temperature, and/or wavelength distribution. An LED lighting system may be capable of mimicking externally monitored, remote controlled, pre-defined, user-selected, or other lighting conditions. An LED lighting system may alloy for a variable lumen output by monitoring a temperature associated with one or more LEDs and increasing or decreasing current flow to maintain the monitored temperature below a maximum temperature. The remaining life may be estimated based on historical runtime and temperature data.

Abstract:
A lighting system 100 and a method of controlling a lighting system are provided. The lighting system comprises a lighting arrangement 106 with a first light emitter 108, a second light emitter 114 and a driving circuitry 104 and comprises a controller 102 providing a control signal 103 to the driving circuitry. The first and second light emitters emit different colors or light L1, L2. The controller is configured to generate the control signal such that a required minimum amount of light is received at a relative position P with respect to the lighting arrangement and that the amount of power used by the lighting arrangement is minimized when the lighting arrangement emits light in accordance with the generated control signal. In the generation of the control signal efficiency ratios R1, R2 for the different light emitters are taken in to account.
