Abstract
Disclosed herein are a light source module and an electronic device using the same. The light source module is disposed in a housing component of the electronic device and includes a light source and a light guide element having a light-entering surface, a light-departing curved surface and a light-reflecting curved surface. The light-entering surface receives the light from the light source. The normal line directions of the light-departing curved surface are approximately perpendicular to the normal line direction of the light-entering surface. The light is reflected by the light-reflecting curved surface and then leaves the light guide element in the normal line directions of the light-departing curved surface.
Claims14
A light source module comprising:
- a light source for emitting a light;
- and
- a light guide element disposed adjacent to the light source and comprising:
- a light-entering surface on one side of the light guide element for receiving the light, wherein the light-entering surface has a light-uniformizing structure;
- a light-departing curved surface on another side of the light guide element, wherein the normal line directions of the light-departing curved surface are approximately perpendicular to the normal line direction of the light-entering surface;
- and
- a light-reflecting curved surface for reflecting the light through the light guide element so that the light leaves the light guide element in the normal line directions of the light-departing curved surface.
An electronic device comprising:
- a housing component having a light pervious portion;
- and
- a light source module disposed in the housing component comprising:
- a light source for emitting a light;
- and
- a light guide element disposed adjacent to the light source and comprising:
- a light-entering surface on one side of the light guide element for receiving the light, wherein the light-entering surface has a light-uniformizing structure;
- a light departing-curved surface on another side of the light guide element, wherein the normal line directions of the light-departing curved surface are approximately perpendicular to the normal line direction of the light-entering surface, and the location of the light-departing curved surface corresponds to the light pervious portion;
- and
- a light-reflecting curved surface for reflecting the light entering the light guide element so that the light leaves the light guide element in the normal line directions of the light-departing curved surface and penetrates through the light pervious portion.
