Abstract
A light source module which includes a flexible circuit substrate, a light-emitting component and a light guide film is provided. The light-emitting component and the light guide film are disposed on the flexible circuit substrate and both of them are on the same side of the flexible circuit substrate. A light-emitting surface faces the light guide film. The width of the light-emitting surface is between the farthest edge from the flexible circuit substrate and the nearest edge to the flexible circuit substrate. In addition, the width of the light-emitting surface is not larger than four times of the thickness of the light guide film.
Claims14
A light source module comprising:
- a flexible circuit substrate;
- a light-emitting component, located on the flexible circuit substrate;
- and
- a light guide film, located on the flexible circuit substrate, wherein the light guide film and the light-emitting component are located on the same side of the flexible circuit substrate, and a first light-emitting surface of the light-emitting component faces the light guide film;
- an opaque film, covering a top surface of the light-emitting component;
- wherein a width is between two edges of the first light-emitting surface, wherein one of the two edges is farthest from the flexible circuit substrate and the other one of the two edges is nearest to the flexible circuit substrate;
- wherein the light guide film has a thickness, and the width of the first light-emitting surface is not larger than four times of the thickness;
- and
- wherein a region of the opaque film directly touches the light guide film, and a length between one side of the region farthest from the first light-emitting surface and the other side of the region nearest to the first light-emitting surface ranges from 2 mm to 3 mm.
A light source module comprising:
- a flexible circuit substrate;
- a light-emitting component, located on the flexible circuit substrate;
- and
- a light guide film, located on the flexible circuit substrate, wherein the light guide film and the light-emitting component are located on the same side of the flexible circuit substrate, and a first light-emitting surface of the light-emitting component faces the light guide film;
- an opaque film, located on a side of the light guide film opposite to the flexible circuit substrate;
- wherein a width is between two edges of the first light-emitting surface, wherein one of the two edges is farthest from the flexible circuit substrate and the other one of the two edges is nearest to the flexible circuit substrate;
- wherein the light guide film has a thickness, and the width of the first light-emitting surface is not larger than four times of the thickness;
- and
- wherein the opaque film extends to directly touch a top surface of the light-emitting component.
