With reference to Fig. 3, its expression is according to the sectional view of the light source module of embodiments of the invention two.In Fig. 3, light source module 200 comprises adjacent cathode tube 102, transmission protective layer 204 and reflected coat layer 206, and transmission protective layer 204 has a groove 208.Transmission protective layer 204 is that the mode with ejection formation is formed at outside the cold-cathode tube 102, in order to coat the two ends and the part pipe shaft of cold-cathode tube 102, makes cold-cathode tube 102 exposed its part-structures in groove 208 and outside the upper surface 204a of transmission protective layer 104.
Certainly, the design of transmission protective layer 204 of the present invention is to protect the structure of cold-cathode tube 102, avoids cold-cathode tube 102 to be collided or external force effect such as extruding produces down and damages.
Reflected coat layer 206 is disposed on the part pipe shaft of cold-cathode tube 102 in the mode of electroplating, in order to reflect the light that cold-cathode tube 102 is produced.It should be noted that reflected coat layer 206 and groove 208 are two of pipe shaft that just lay respectively at cold utmost point pipe 102.In addition, reflected coat layer 206 is can guide light that cold-cathode tube 102 produced to be transmitted through the external world via the upside of light source module 200, to improve luminescence efficiency.
Embodiment three
With reference to Fig. 4, its expression is according to the sectional view of the light source module of embodiments of the invention three.In Fig. 4, light source module 300 comprises cold-cathode tube 102, transmission protective layer 304 and reflected coat layer 306.Transmission protective layer 304 is that the mode with ejection formation is formed at outside the cold-cathode tube 102, in order to coat whole pipe shafts of cold-cathode tube 102.Wherein, present embodiment and embodiment one and embodiment two differences are that not exposed its part-structure of the cold-cathode tube 102 of present embodiment is outside the upper surface 104a of transmission protective layer 304, and promptly cold-cathode tube 102 is embedded in the transmission protective layer 304 fully.
Certainly, the design of transmission protective layer 304 of the present invention is to protect the structure of cold-cathode tube 102, avoids cold-cathode tube 102 to be collided or external force effect such as extruding produces down and damages.
Reflected coat layer 106 is disposed on the part pipe shaft of cold-cathode tube 102 in the mode of electroplating, in order to reflect the light that cold-cathode tube 102 is produced.In addition, reflected coat layer 106 is can guide light that cold-cathode tube 102 produced to be transmitted through the external world via the upside of light source module 100, to improve luminescence efficiency.
Embodiment four
With reference to Fig. 5, its expression is according to the sectional view of the light source module of embodiments of the invention four.In Fig. 5, light source module 400 comprises cold-cathode tube 102, transmission protective layer 404 and reflected coat layer 406.Transmission protective layer 404 is that the mode with ejection formation is formed at outside the cold-cathode tube 102, in order to coat whole pipe shafts of cold-cathode tube 102.
The design of transmission protective layer 404 of the present invention is to protect the structure of cold-cathode tube 102, avoids cold-cathode tube 102 to be collided or external force effect such as extruding produces down and damages.
Reflected coat layer 406 is to be disposed on the part pipe shaft of cold-cathode tube 102 in the mode of electroplating, in order to reflect the light that cold-cathode tube 402 is produced.In addition, reflected coat layer 406 is can guide light that cold-cathode tube 102 produced to be transmitted through the external world via the upside of light source module 100.
It should be noted that; present embodiment and embodiment three differences are; present embodiment is especially in the upper surface 404a of transmission protective layer 404 projection one light harvesting district 408, and light harvesting district 408 and reflected coat layer 406 just lay respectively at the both sides of the pipe shaft of cold-cathode tube 102.And light harvesting district 408 is in order to assemble the light that cold-cathode tube 102 is produced, to improve luminescence efficiency.
With reference to Fig. 6, its expression is the process flow diagram of the manufacture method of light source module of the present invention.In Fig. 6, at first, in step 502, provide a light source with elongated pipe shaft, for example be cold-cathode tube.Then, enter in the step 504, form a transmission protective layer outside light source, and transmission protective layer coats the part pipe shaft of light source at least.For example, the present invention forms transmission protective layer outside light source in the mode of ejection formation.Then, enter in the step 506, form a reflected coat layer in transmission protective layer, and reflected coat layer is positioned at a side of the pipe shaft of light source.For example, the present invention forms reflected coat layer outside the part pipe shaft of light source in the mode of electroplating, and this method so far finishes.So the present invention can obtain above-mentioned light source module 100,200,300 and 400 with the manufacture method of Fig. 6.
Yet those skilled in the art can understand that technology of the present invention is not limited to this; for example; under the design premises of the reflected coat layer light that reflection source provided effectively; the present invention is that the part pipe shaft that reflected coat layer can be disposed at light source reaches outward outside the lower surface of transmission protective layer, to improve the luminescence efficiency of light source.Wherein, transmission protective layer is the clear plastic and the clear glass of high-transmission rate, and reflected coat layer is a metal.In addition, the two ends of light source module also have circuit and connect transmission protective layer and be exposed to extraneous design, use for light source and extraneous circuit electric connection, and reach luminous effect.
In addition, in light source module of the present invention, the cross sectional shape of transmission protective layer can be designed change according to the cross sectional shape of different light source, with the effect of the structure that reaches the protection light source, and increases the vibration strength and the crushing resistance of the structure of light source.
It should be noted that light source module of the present invention is on the configurable ray machine in scanner (chassis), in order to provide light to scan the action of a file to be scanned, the process that how to scan file to be scanned as for ray machine is not being given unnecessary details at this.Wherein,, light source module is disposed on the lamp socket on the ray machine but being mode with snapping, even, under the situation of omitting lamp socket,, light source module directly is disposed on the ray machine but being mode with snapping.
The advantage of disclosed light source module of the above embodiment of the present invention and manufacture method thereof comprises:
1. the design of its transmission protective layer can be protected the structure of light source, and increases the vibration strength and the crushing resistance of light source, produces the phenomenon of damaging when avoiding light source to be subjected to external force.
2. the light that the design of its reflected coat layer can reflection source produces, and directing light is transmitted through the external world via a side of light source module, makes the light that light source produced to be emitted to the external world towards same direction, to improve luminescence efficiency and light source accuracy.
3. but light source module of the present invention is directly to be disposed on the ray machine in the snapping mode, but the assembleability of simplification device and reduce user's built-up time.
In sum; though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; any present technique field those skilled in the art; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention should be as the criterion with the scope that claims were defined of application.
