    摘要: An LED security light includes a power supply unit comprising a first power source, a second power source and a power switching circuitry, wherein the power switching circuitry utilizes a detector to detect an available electric power in the first power source or in the second power source, and operates with the available electric power detected as a criterion to selectively connect an LED load to at least one of the first power source and the second power source for performing an illumination mode in responding to signals generated by a light sensing unit, a motion sensor unit, or at least one external control unit. In an exemplar, the first power source is an AC power source or a solar power module, and the second power source is a battery unit or a rechargeable battery module.

    摘要: An LED lifestyle lighting solution using microcontroller technology to control LED load for managing nighttime illumination is disclosed, wherein the nighttime illumination is divided into a first stage being a high power illumination for a preset time period and a second stage being an energy saving/security illumination. The time period of the first stage high power illumination is managed by a virtual timer which is programmable and dynamically variable according to a user's living habits and needs. The second stage energy saving illumination having four options is produced by adequate combinations of LED load dimming and motion sensor operation. The LED characterized by a limited working voltage range, namely, Vth

    摘要: A sensing module detachably connectable to a light body includes a sensing unit and a connecting module. The sensing unit has at least one sensor, a control circuit and at least one parameter adjusting element. The sensor and the parameter adjusting element are electrically coupled to the control circuit, and the sensing module is electrically coupled and mechanically mounting to the light body via the connecting module. The sensing module further includes a socket allowing a light source to be connected to the sensing module. The sensing module can also include a light source. The user can manipulate the illumination characteristic through the sensing module.
