Electronic apparatus

Abstract

An electronic device includes a housing, a circuit board, a heat sink, a light source, and a reflective layer. The housing includes a light-transmitting portion. The circuit board is disposed within the housing. The heat sink, the light source, and the reflective layer are disposed on the circuit board. The heat sink is located between the circuit board and the light-transmitting portion, and includes a shielding portion and an opening penetrating the shielding portion. The light source and the reflective layer are located between the circuit board and the heat sink, with the light-emitting side of the light source facing the reflective layer. The light source is shielded by the shielding portion in a direction perpendicular to the circuit board. In a direction perpendicular to the circuit board, the reflective layer is positioned opposite the opening, and the opening is positioned opposite the light-transmitting portion.
