20150280426 | RELAY PROTECTOR DEVICE AND OPERATION METHOD FOR THE SAME - A relay protector device is provided, mitigating the impact of the inrush current to a circuit and comprising a relay circuit; a driver circuit, connecting in parallel with the relay circuit; and a controller, connecting through a signal to the relay circuit and the driver circuit and being driven by a driving signal to trigger in sequence the relay circuit and the driver circuit to operate. | 10-01-2015 |
20150216015 | SELF-ADAPTIVE BRIGHTNESS SENSOR LIGHT, BRIGHTNESS SENSOR MODULE, AND BRIGHTNESS-ADJUSTING METHOD OF THE SAME - A self-adaptive brightness sensor light performs a brightness level adjusting procedure upon activating a lamp body thereof. The brightness level adjusting procedure has steps of acquiring an ambient brightness level, determining if the ambient brightness level is greater than a daytime bright level, and if positive, generating a new daytime brightness level to make it greater than the ambient brightness level, and deactivating the lamp body according to the new daytime brightness level. The daytime brightness level can be automatically adjusted after the lamp body is activated, so as to avoid repeated on-and-off condition of the sensor lights that occur due to immediate deactivation of the sensor light after the sensor light is turned on. | 07-30-2015 |
20140203712 | OCCUPANCY SENSOR FOR CONTROLLING AN LED LIGHT - An occupancy sensor for an LED module has an occupancy sensing module, a main control module and a current control module. The occupancy sensing module has capability of sensing occupancy status of a specific area. The main control module has capability of processing the signal from the occupancy sensing module and controlling. The current control module connects to the main control module and includes a current regulator, a power switch, a current sensor and a current controller. The current control module adjusts the duty cycle of the power switch based on the detected current through the LED module, thereby stabilizing the current output for the LED module. | 07-24-2014 |
20140061480 | OCCUPANCY SENSOR DEVICE DESIGN FOR FIXTURE INTEGRATION AND A LIGHT WITH THE SAME - An occupancy sensor device has a sensor and a fastener. The sensor has a body and a connector. The body has a detector and a lens. The lens covers the detector. The connector is formed on the body. The fastener is connected securely to the connector of the sensor. When the occupancy sensor device is installed on a light, the connector is mounted through a sensor hole of a light cover first, and the fastener is connected securely to the connector. Then the installation is completed and the sensor device is mounted securely on the light cover. Because the sensor has the connector directly formed on the body and the connector can be connected securely to the fastener, the sensor device is easily mounted on various kinds of lights regardless of the structure of the base. | 03-06-2014 |
20130284932 | FLAT LENS WITH MULTIPLE FOCAL LENGTHS AND A PASSIVE INFRARED SENSOR DEVICE WITH THE SAME - A flat lens with multiple focal lengths has a lens segment. The lens segment is flat and has multiple convex lenses. The convex lenses are mounted on one of the surfaces of the lens segment, and have multiple focal lengths. With the different focal lengths of the convex lenses, multiple distances of detection of a sensor behind the lens segment can be extended to different lengths, and further increase the range of detection. Besides, with different distances of detection, the accuracy of detection would be enhanced effectively, and the erroneous estimate on a volume of the object would reduce effectively. Furthermore, because a shape of the lens segment is flat, the lens as described is more innovative and aesthetically appealing, and is relatively easier to match the building's design or decoration. | 10-31-2013 |
