Abstract: Disclosed are a power consumption reduction circuit for Graphics Processing Units (GPUs) in a server and a server. The power consumption reduction circuit includes a frequency reduction control chip. The frequency reduction control chip, after receiving an overpower alarm signal generated by a Power Supply Unit (PSU), generates a frequency reduction control signal to a Power Break (PWRBRK) pin of each GPU so as to start a frequency reduction operation of each GPU. It can be seen that, in the present application, an underlying hardware circuit is directly used for implementation with relatively quick responses and without intervention of an operating system, whereby the whole frequency reduction operation of the GPU may be completed within 5 ms, and the PSU is prevented from triggering overpower protection within relatively short time. Therefore, loss of service data of a user caused by an exceptional power failure of the server is avoided.

Abstract: A lighting apparatus includes a light source, a silicon controlled rectifier, a rectifier and a current source circuit. The light source has multiple LED modules with different light parameters. The silicon controlled rectifier filters a filtering ratio of an input AC power to a filtered AC power. The filtering ratio is associated with a control angle by supplying a control voltage to the silicon controlled rectifier. The maintainer circuit maintains a working current to the silicon controlled rectifier even when the control angle is large causing the volume of the filtered AC power less than a threshold. The current source circuit receives the DC power. The current source circuit has a wall switch input for connecting to a wall switch. An on-off input pattern of the wall switch is detected by the current source circuit for generating multiple corresponding driving currents.
