    摘要: A LED drive circuit according to the present invention comprises a controller and a programmable signal. The controller generates a switching signal coupled to switch a magnetic device for generating an output current to drive a plurality of LEDs. The programmable signal is coupled to regulate a current-control signal of the controller. The switching signal is modulated in response to the current-control signal for regulating the output current, and the level of the output current is correlated to the current-control signal.

    摘要: The present invention provides a control circuit for dimming LED lighting. The control circuit comprises a voltage divider, a controller and an adaptive bleeder. The voltage divider receives an input voltage from an input terminal to generate a dimming signal. The controller generates a switching signal in response to the dimming signal. The controller further generates a control signal in response to the input voltage. The adaptive bleeder receives the control signal and draws a bleeder current from the input terminal in response to the control signal.

    摘要: A packaging structure of an optical motion sensor includes a packaging substrate, an optical detection module, and a packaging mask. The optical detection module is provided on the packaging substrate and is electrically connected with the packaging substrate. The packaging mask is disposed on the packaging substrate to package the optical detection module. Further, the packaging mask is provided therein with a transparent body and a hole formed on the packaging mask. Via the above structure, light, passes through the transparent body inside the hole, and thus shines the optical detection module. In this way, the optical detection module is isolated from dirt in the air, thereby reducing possible damage or interference and reducing the volume of the packaging structure.
