    Abstract: The present invention discloses a tri-state I/O port. The tri-state I/O port comprises a tri-state logic block, a weak buffer and a delay block. The input terminals of the tri-state logic block are connected to data and OE (output enable) signals. When OE signal is enabled, the output terminal of the tri-state I/O block is pulled high when the data is high while the output terminal is pulled low when the data is low. The input terminal and the output terminal of the weak buffer are connected to the output terminal of the tri-state logic block. And the input terminal of the delay block is connected to the output terminal of the tri-state logic block while the output terminal of the delay block is fed back to the tri-state logic block. When the output terminal of the tri-state logic block is low to high/high to low, the weak buffer is active and maintains the output terminal of the tri-state logic block weak high/low while the delay block turns off the pull high/low function of the tri-state logic block.

    Abstract translation: 本发明公开了一种三态I / O端口。 三态I / O端口包括三态逻辑块，弱缓冲器和延迟块。 三态逻辑块的输入端连接到数据和OE（输出使能）信号。 当OE信号使能时，数据为高电平时，三态I / O模块的输出端子拉高，而数据为低电平时，输出端子拉低。 弱缓冲器的输入端子和输出端子连接到三态逻辑块的输出端子。 并且延迟块的输入端子连接到三态逻辑块的输出端，而延迟块的输出端反馈到三态逻辑块。 当三态逻辑块的输出端子由低到高/高到低时，弱缓冲器有效，并且三态逻辑块的输出端子在高电平/低电平时保持低电平，而延迟模块关闭拉高 /三态逻辑块的低功能。

    Abstract: A reflective unit (16, 26, 26a) for using with a light guiding element (14, 24, 24a) is disclosed. The light guiding element (14, 24, 24a) includes a light entrance portion (144, 244) and a light exit portion (148, 248, 248a). The light exit portion (148, 248, 248a) has a first concave portion (1482, 2482, 2482a) dented toward the light entrance portion (144, 244). The reflective unit (16, 26, 26a) includes a fixing member (162, 262, 262a) and a reflective member (164, 264). The fixing member (162, 262, 262a) is arranged around the perimeter of the upper end of the light exit portion (148, 248, 248a). The reflective member (164, 264) is arranged on the fixing member (162, 264, 262a) for covering the first concave portion (1482, 2482, 2482a) and forming a conical-shaped light propagating space (19, 29).

The light-emitting diode lamp (1) has a circuit board (11), at least one light-emitting diode (12), a thermal module (13), and a rectifying circuit (14). The light-emitting diode (12) is installed on the circuit board (11), the thermal module (13) provides a heat-dissipating function to the light-emitting diode (12), and the rectifying circuit (14) provides a rectified power to the light-emitting diode (12). When a utility power (3) is supplied to the dimmer (4) and the external power box (2), a variable resistor of the dimmer (4) is adjusted and the utility power (3) is controlled by the external power box (2), thus adjusting the brightness of the light-emitting diode (12).
