20120188752 | LIGHTING APPARATUS WITH HYBRID POWER SUPPLY DEVICE, AND METHOD UTILIZING THE SAME - A light apparatus with a hybrid power supply device and method utilizing the same are disclosed. The light apparatus includes an LED module, a solar module, an auxiliary power module, a voltage level detection circuit, a first switch unit, and a second switch unit. When a voltage of a solar electric power generated by the solar module is greater than a predetermined value, the voltage level detection circuit provides an electrical connection between the solar module and the LED module for enabling a transmission of the solar electric power to the LED module. When the voltage of the solar electric power is smaller than the predetermined value, the voltage level detection circuit provides an electrical connection between the auxiliary power module and the LED module for enabling a transmission of an auxiliary electric power generated by the auxiliary power module to the LED module. | 07-26-2012 |
20140375220 | TWO-LEVEL LED SECURITY LIGHT WITH MOTION SENSOR - 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. | 12-25-2014 |

20150054413 | SECURITY LIGHT WITH LIFESTYLE SOLUTIONS - A lifestyle lighting solution using microcontroller technology for controlling nighttime illumination is disclosed wherein the night time illumination is divided into two stages with the first stage being a full power illumination for a preset time period and the second stage being an energy saving/security illumination. The time period of the first stage full power illumination is managed by a virtual timer which is programmable and dynamically variable according to the home owners' living habits and needs. The second stage energy saving illumination with four options is produced by different combinations of dimming techniques and motion sensor. The lifestyle illumination also using microcontroller technology to replace the function of photo cell enables the users to manage their time table of home lighting performance for both indoor and outdoor application. The present invention provides home owners possibility to choose among different working modes integrated in a single lighting device. | 02-26-2015 |
