摘要： A color temperature switching scheme for an LED lighting device is disclosed. The color temperature switching scheme comprises a plurality of different color temperature performances correspondingly generated by a plurality of different paired combinations of a first electric power allocated to a first LED load emitting a light with a first color temperature and a second electric power allocated to a second LED load emitting a light with a second color temperature such that a mingled color temperature between the first color temperature and the second color temperature can be generated thru a light diffuser. For tuning the mingled color temperature of the LED lighting device a reverse yet complementary power adjustment process for distributing a total electric power T between the first LED circuit and the second LED circuit is required such that a total light intensity remains unchanged while the mingled color temperature is being adjusted.

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： A sensing lamp includes a lamp body connected with a sensing module. The sensing module is configured with a sensing unit and a cover partially covering the sensing unit. The sensing unit has a passive infrared ray sensor and at least one parameter adjusting element. The sensing unit is rotatable around a central axis passing thru the sensing module and the lamp body. When the sensing unit is rotated to a first angle position, the at least one parameter adjusting element is blocked and the passive infrared ray sensor is able to perform a forward sensing function. When the sensing unit is rotated to a second angle position, the at least one parameter adjusting element is exposed to being conveniently adjusted. The passive infrared ray sensor is configured with a partial cylindrical condensing lens for performing a horizontal detection angle ranging from 100 degrees to 270 degrees.

摘要： A lifestyle LED lighting solution is configured with a timer to convert from performing a first illumination mode to performing a second illumination mode at a preset time point controlled by the timer, wherein the first illumination mode and the second illumination mode are designed to perform different lighting characteristics including a light intensity and a light color temperature. The first illumination mode is a general illumination mode while the second illumination mode is an energy saving mode. The timer can be an anytime setting timer, a fixed time point timer, a fixed time period timer or a clock timer. The anytime setting timer is also usable for replacing a photo sensor to automatically turn on and turn off an LED light. The clock timer can be used for controlling on/off performance of the LED light according to a clock time schedule.
