Abstract: A LED illuminating device includes a plurality of LED tubes, electrically connected in series and/or in parallel, and one LED tube driver, separately disposed outside the LED tubes and spaced apart from the LED tubes. The LED tube driver is electrically connected to the plurality of LED tubes through an external extension line. The LED tube driver and each LED tubes can be replaced individually so as to reduce the replacement cost. In addition, the LED tube driver is spaced apart from the LED tube, that the LED tube driver can avoid being damaged because of the heat. The lifetime of the LED tube driver is prolonged and the replacement frequency of the LED tube driver is reduced. Therefore, the LED illuminating device of the present invention has low maintenance cost.

Abstract: Disclosed is a router device for transmitting and receiving a networking signal via a network connection. The network connection includes a wireless connection or a wired network connection. The router device comprising: a wireless networking means for transmitting and/or receiving the networking signal within the wireless network connection, a wired networking means for transmitting and receiving the networking signal by a wire within the wired network connection, a memory for storing picture data, and a touch screen for inputting a network configuration of the wireless network connection and/or the wired network connection, for displaying the result of network configuration, and for displaying the picture data.

Abstract: The present invention discloses a premium power amplifier applied in an antenna module, and the premium power amplifier includes a first transmission unit, having two symmetrical and identical first arc-shaped circuits, two secondary power amplifiers connected in parallel with each other, and a second transmission unit having two symmetrical and identical second arc-shaped circuits, in which those components above are installed between a power amplifier and an output terminal of the antenna. So that the output power of the antenna can be improved greatly, and the effective transmission distance can be extended.
