Electronic apparatus

Abstract

An electronic device includes a housing, a circuit board, a light source, and a heat sink. The circuit board is disposed within the housing. The heat sink is disposed on the circuit board and includes a shielding portion and an opening penetrating the shielding portion. The light source and the heat sink are disposed on the same side of the circuit board. The light source is located either inside or outside the opening. When the light source is located inside the opening, the shielding portion shields the light source in a first direction parallel to the circuit board. When the light source is located outside the opening, the shielding portion shields the light source in a second direction perpendicular to the circuit board.

Claims

1. An electronic device, comprising: A shell; A circuit board is housed within the housing; A heat sink is disposed on the circuit board and includes a shielding portion and an opening portion passing through the shielding portion; and a light source is disposed on the same side of the circuit board as the heat sink, the light source being located inside or outside the opening portion; when the light source is located inside the opening portion, the shielding portion shields the light source in a first direction parallel to the circuit board, and when the light source is located outside the opening portion, the shielding portion shields the light source in a second direction perpendicular to the circuit board.

2. The electronic device as claimed in claim 1, wherein the housing includes a first housing portion, a second housing portion relative to the first housing portion, and a third housing portion located between the first housing portion and the second housing portion, the circuit board is disposed between the first housing portion and the second housing portion, and has a first surface facing the first housing portion and a second surface facing the second housing portion, and the light source is disposed on the first surface or the second surface.

3. The electronic device as claimed in claim 2, wherein the light source and the heat sink are disposed on the first surface, and the light source is located within the opening, and the shielding portion shields the light source in the first direction.

4. The electronic device as claimed in claim 3, wherein the third housing portion is a light-transmitting area at least between the first surface and the first housing portion, and a light-emitting side of the light source faces away from the light-transmitting area.

5. The electronic device as claimed in claim 4, wherein in the second direction perpendicular to the first direction, a height of the light-transmitting area is greater than a height of the shielding portion.

6. The electronic device as claimed in claim 5, wherein the shielding portion surrounds the light source and the shielding portion separates the light source from the light-transmitting area in the first direction.

7. The electronic device as claimed in claim 2, wherein the light source is disposed on the second surface, and the heat sink is disposed between the second surface and the second housing portion, the light source is located outside the opening portion, and the shielding portion shields the light source in the second direction.

8. The electronic device as claimed in claim 7, wherein the light source is located within an orthographic projection range of the shielding portion on the second surface.

9. The electronic device of claim 7, wherein the second housing has a light-transmitting area located at the opening, and the third housing is a non-light-transmitting area at least between the second surface and the second housing, and the light-emitting side of the light source faces the non-light-transmitting area.

10. The electronic device of claim 9, wherein in the second direction, a height of the non-transparent area is greater than a height between the shielding portion and the second surface.

11. The electronic device of claim 9, wherein in the first direction, a distance between the emitting side of the light source and the non-transparent area is greater than a distance between the emitting side of the light source and an edge of the opening.

12. The electronic device of claim 9, wherein, in the first direction, one edge of the opening is a distance from the light-emitting side of the light source.

13. The electronic device as claimed in claim 1, wherein the heat sink comprises heat sink fins or a heat sink plate.
