The light guide bar includes a bar body and a plurality of prisms. The bar body has a first receiving end, a light-exiting surface, and a structure surface. The light-exiting surface is opposite to the structure surface and faces the sensing area while the first receiving end is connected between an end of the light-exiting surface and an end of the structure surface. The prisms are formed on the structure surface. Each prism includes a first surface and a second surface respectively having a first angle and a second angle with respect to the structure surface, wherein the second surface is closer to the first receiving end than the first surface, and the second angle is larger than or equal to the first angle.

Abstract: A light source device includes a lens and a light source disposed under the lens. The lens has a light-emitting top surface and a bottom surface opposite to the light-emitting top surface. The bottom surface concaves towards the light-emitting top surface to form a hole and has a gouge surrounding the hole with an inclination towards the edge of the hole. The hole is formed from the surrounding of a first inner wall surface and a second inner wall surface. The light source is disposed below the bottom surface and corresponds to the hole.

Abstract: The disclosure discloses an electronic apparatus and a power management method are disclosed. The electronic apparatus includes a power board, a remote-controller receiving board and a mainboard. The power board is configured for converting public electricity into a standby voltage and a main power voltage. The remote-controller receiving board, coupled with the power board, is configured to be operated with the standby voltage. When the remote-controller receiving board receives a control signal from a remote controller, the remote-controller receiving board sends a power-switching signal to the power board. The power board starts or stops supplying the main power voltage according to the power-switching signal. The mainboard, coupled with the power board, is configured to be operated with the main power voltage.
