摘要： A method for optimizing an LED lighting system cost includes steps of determining LED costs, power source costs, and total costs associated with a plurality of LED quantities, and identifying a lowest total cost as an optimal cost. A LED lighting system includes an LED operated by a constant-current driver at less than its maximum current capacity. A programmable controller including a feedback routine is used to compensate for intensity drift as an LED ages. Other embodiments of LED lighting systems include multiple LEDs producing light having various spectrums to optimize the lighting system efficiency and the effectiveness. A charge controller including an MPPT routine is advantageously employed with a LED lighting system powered by a limited-capacity power source.

摘要： A compound energy storage system made up of two energy storage devices of different characteristics. The first device is a deep cycle lithium ion battery (or similar characteristics) and the second device is deep cycle lead-acid battery (or similar). Both devices are connected in parallel with control circuitry that manages the charging/discharging of each device in such a way that maximizes lifetime of the combined energy storage system when powering a load. First device acts as primary power source and is cycled daily under normal conditions. Second device provides additional power for periods of extended power draw and low temperatures, when the first device is unable to deliver sufficient energy or unable to take a charge. Excess power from external energy source or reserved in one of the devices shall be used to power components that will control device temperature and optimize overall performance of the storage system.
