Structure of light-source module

A light-source module for an optical scanner, the light-source module comprising:

• a lampholder comprising a hollow structure with a concave groove for accommodating a lamp to provide light, wherein the concave groove has a shape corresponding to the lamp, wherein a reflection assembly is arranged to reflect the light emitted from the lamp, wherein the lampholder further includes an opening positioned such that both the light of the lamp and the reflected light from the reflection assembly pass through the opening and are projected onto a scanning range, and wherein the reflection assembly has a first reflection part and a second reflection part, the first reflection part positioned at least partially above an upper portion of the lamp to reflect the partially dissipated light into the scanning range, the second reflection part located between the surface of the hollow structure and the lamp to reflect light emitted from the lamp through the opening and onto the scanning range, the second reflection part at least partially wound around the lamp in an arc structure.

An optical scanning apparatus comprising:

• a light holder having a curved surface capable of accommodating a light, an opening, a first reflection portion capable of reflecting light emitted from the light onto a first scanning range of a document, and a second reflection portion arranged in a light path of the light that is capable of reflecting dissipated light into the first scanning range and blocking the dissipated light from reaching a different, second scanning range of the document, wherein the second reflection portion is directly connected to the light.

An optical scanning apparatus comprising:

• means for reflecting light emitted from a lamp into a first scanning range of a document with a first reflection portion;
• means for reflecting dissipated light that is reflected from the first reflected portion into the first scanning range, wherein the means for reflecting dissipated light is configured to prevent dissipated light from striking a second scanning range of the document with a second reflection portion that is arranged in a light path of the dissipated light, and wherein the means for reflecting dissipated light is located in a light path of the lamp and is directly connected to the lamp.

A light-source module for optical scanning comprising:

• a lampholder for accommodating a lamp, wherein a first reflection piece is arranged at an inside surface of the lampholder to reflect light emitted from the lamp, wherein the lampholder further includes an opening positioned such that both the light of the lamp and the reflected light from the first reflection piece pass through the opening and are projected onto a scanning range, and wherein a second reflection piece is arranged at a portion of is directly coupled to the lamp to reflect partially dissipated light into the scanning range.
