Abstract: Disclosed is an outdoor device management system, and a recognition device having a blank record is installed in the outdoor device and includes a first transmission module for electrically connecting a second transmission module of an electronic device such as a mobile phone or a tablet PC. When the outdoor device is installed, an identification code of the electronic device is set and provided to the outdoor device, while coordinates of the outdoor device are captured to form installation data containing the identification code, and the installation data are transmitted to the terminal device, so that the terminal device labels the outdoor device at a corresponding location of a map to complete the installation operation, and the electronic device transmits the identification code or installation data to the recognition device through the second transmission module and the first transmission module for storage and record.

Abstract: Disclosed is a Z-shaped lamp panel applied in a lamp and configured as a comb-shaped body. The Z-shaped lamp panel includes an installing portion disposed at a position corresponding to a comb-handle position and a plurality of carrying portions corresponding to comb-tooth positions respectively. The installing portion is coupled to a side of the carrying portions, and the carrying portions are arranged with an interval apart from each other and provided for installing a plurality of light emitting diodes. Therefore, the cost of the lamp panel can be reduced while the lamp can maintain the light emitting diodes in a matrix form to ensure a maximum illumination range.

Abstract: An outdoor device management system, in installations of at least one outdoor device such as a road lamp, a street trash can, an electrical box, a monitor, an electric meter or a sprinkler, uses a wireless sensor with a global positioning system (GPS) chip to sense an identification element of the outdoor device, capture a unique identifier address (UID) and generate sensed data containing coordinate data and then transmits the sensed data to a terminal device, labeling the outdoor device on a corresponding position in a map, and transmitting an operation instruction to trigger and control operations of the corresponding outdoor device. The outdoor device includes a detection element for detecting and reporting current operating status for the terminal device, using the map to plan an optimal path to expedite going to maintain the outdoor device when abnormality occurs so as to improve the convenience and accuracy of management.

Abstract: A light emitting diode (LED) down lamp with a replaceable color temperature filter uses a plurality of blue LEDs as a light source and includes a color temperature filter and a fixing ring. The color temperature filter is installed across the top of the down lamp to apart cover the LEDs with a distance, and then fixed by the fixing ring. Therefore, the color temperature filter can be replaced flexibly with other one in different color temperature one by removing or assembling the fixing ring to change the light projected from the LEDs into different color tone for fitting studio, stage or indoor space applications. Such lamp achieves the effects of enhancing the illumination function of a single down lamp, reducing the inventory cost and improving the practicality.
