Abstract
The invention provides an optical-mechanical system which comprises a circuit board, a series of light-emitting components and a light-diffusion component. The light-emitting components are fixed on the circuit board. The light-diffusion component comprises a plane and an arc surface fixedly connected below the plane. The plane is used for diffusing spot light sources emitted from the light-emitting components into uniform line light sources. The arc surface is used for converging the diffused line light sources. By the optical-mechanical system, increase of the cost of users as a result of increase of the light-emitting components can be avoided.
Description
Technical field
The present invention relates to a kind of optical-mechanical system, relate in particular to a kind of optical-mechanical system of scanner.
Background technology
Under the prior art, the optical-mechanical system of scanner is put in the diffusion sheet in light-emitting component the place ahead and is constituted by a circuit board, a series of light-emitting component of fixedly putting on circuit board and usually.This light-emitting component sends spot light under the ordering about of circuit, this diffusion sheet is used for the spot light that light-emitting component sends is diffused into the line source of a series of diffusions, and utilizes this line source to scan.Yet, in the process of diffusion sheet, can directly cause the intensity of light source to reduce with the spot light diffusion, thus influence scanning effect.In order to overcome above-mentioned defective, usually through increasing the intensity that light-emitting component promotes whole light source, but can have the too much light-emitting component of increase that ends limit, and too much light-emitting component will make user's cost up because the size of circuit board is limited.
Summary of the invention
Main purpose of the present invention is to provide a kind of optical-mechanical system, and it after diffusing into line source through the spot light that light-emitting component is sent is converging line source, improves light-source brightness, thereby solves the above problems.
The present invention provides a kind of optical-mechanical system; Comprise a circuit board and a series of light-emitting component that is fixed on the circuit board; This optical-mechanical system comprises that also one is fixed in the astigmatic element in light-emitting component the place ahead; This astigmatism element comprises that a plane body and is fixedly connected on the arcwall face body of plane body below, and the spot light that this plane body is used for that light-emitting component is sent diffuses into uniform line source, and this arcwall face body is used to converge the line source that is spread.
The present invention also provides a kind of optical-mechanical system; Comprise that a circuit board, a series of light-emitting components and that are fixed on the circuit board are fixed in the astigmatism plate in light-emitting component the place ahead; This optical-mechanical system comprises that also one is fixed in the convex lens in astigmatism plate the place ahead; The spot light that this astigmatism plate is used for that light-emitting component is sent diffuses into uniform line source, and these convex lens are used to converge the line source that is spread.
Optical-mechanical system of the present invention, after it diffused into line source through the spot light that light-emitting component is sent, the line source after will spreading converged, and improved light-source brightness, thereby avoided increasing a plurality of light-emitting components, increased user cost.

The following specific embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
The specific embodiment
Please refer to shown in Figure 1ly, this optical-mechanical system 10 comprises that a circuit board 11, a series of light-emitting components 12 and that are fixed on the circuit board 11 are fixed in the astigmatic element 13 in light-emitting component 12 the place aheads.In this embodiment, this light-emitting component 11 is LED lamp or radium-shine lamp etc.
Please refer to shown in Figure 2ly, this astigmatism element 13 comprises that a plane body 131 and is fixedly connected on the arcwall face body 132 of plane body 131 belows.This plane body 131 is used for diffusing into uniform line source with coming from the spot light 21 that light-emitting component 12 sends.This arcwall face body 132 is used for the line source of plane body 131 diffusions is converged, thereby promotes the brightness of the line source after the diffusion.In this embodiment, this arcwall face body 132 is convex lens.In other embodiments, this arcwall face body 132 also can be the lens that other have the light source aggregation feature.
Please refer again to shown in Figure 2ly, wherein three spot lights 21 sending of three light-emitting components 12 are incident to plane body 131.131 pairs of these three spot lights 21 of this plane body spread.Line source after 131 diffusions of 132 pairs of plane bodies of this arcwall face body converges, and as wherein there being three line sources 1,2,3 vertical through being converged at the F point behind the arcwall face body 132, at this, this F point is the focus of convex lens.And other line source such as line source 4,5 converged at convergent point C etc. through arcwall face bodies 132 backs, thus the line source after plane body 131 diffusions converged through arcwall face body 132, and the line source after converging is used to scan etc.In said process; When spot light 21 was diffused into the line source of dispersing, whole light-source brightness will reduce owing to the diffusion of line source, and is darker if scan the effect that will cause scan with the line source of this diffusion this moment; Therefore be necessary to promote the brightness of integrated light source; So then the line source after will spreading converges through arcwall face body 132 and promotes light-source brightness, the line source after final use is converged scans, and will make that so the effect of scanning is brighter.
Please refer to shown in Figure 3ly, be the sketch map of optical-mechanical system 20 in other a kind of embodiment.This optical-mechanical system 20 comprises that astigmatism plate 14 and that a circuit board 11, a series of light-emitting component 12, that is fixed on the circuit board 11 are fixed in light-emitting component 12 the place aheads is fixedly set in the convex lens 15 in astigmatism plate 14 the place aheads.This astigmatism plate 14 is used for the spot light 21 that light-emitting component 12 is sent is diffused into uniform line source.These convex lens 15 are used to converge the line source that is spread.
