Abstract
The present invention relates to an optical mouse capable of improving a spotlight effect, which comprises a light source, a lens, a first reflecting surface, a second reflecting surface, a circular arc surface and an optical sensor. A beam of incident light projected by the light source passes through the lens for focusing, then passes through the first reflecting surface and the second reflecting surface for reflecting, and finally, passes through the circular arc surface for aggregating rays. The rays are projected to an applying surface, and the rays reflected by the applying surface are received by the optical sensor for controlling the operation mechanism of the optical mouse.
Description
Technical field
The invention provides a kind of optical mouse that promotes spotlight effect, refer to that especially a kind of arc surface that utilizes is to promote the optical mouse of spotlight effect.
Background technology
See also Fig. 1, Fig. 1 is the in-built synoptic diagram of known optical mouse 10.Optical mouse 10 comprises a light source 11, convex lens 13, reflecting surface 12,15, a penetration surface 14 and an optical sensor 17.Light source 11 is used for producing light, and convex lens 13 are in order to light focusing, and reflecting surface 12,15 and penetration surface 14 are in order to leaded light, on ray guidance to an application surface 19 that light source 11 is produced.And the light that optical sensor 17 reception application surfaces 19 are reflected is with the running of control optical mouse 10.
As the light path among Fig. 1, light source 11 is in order to produce light, and light forms a light beam via the effect of convex lens 13 earlier, and directive reflecting surface 15.Then, the light beam of directive reflecting surface 15 successively passes through the reflex of reflecting surface 15 and 12, and this light beam is projected on the application surface 19 again via the refraction action of penetration surface 14 at last.
Because each reflecting surface and penetration surface are all the plane, so light beam is when carrying out reflex, and the spotlight effect of this light beam in prism is not remarkable.In other words, the light beam of scioptics 13, under the constant condition of the gross energy of light beam, if the width of light beam is narrower, its light intensity is relatively large; Otherwise if the wider width of light beam, its light intensity is less relatively.Therefore the light path from Fig. 1 can learn that when light beam proceeded to penetration surface 14 from reflecting surface 12, the width of light beam had broadened, and meaned light intensity and had died down.Therefore, light beam in prism through can light intensity being weakened after twice the reflex.And the light that light beam reflects via penetration surface 14 does not at last strengthen the effect of light intensity yet.If the beam area A1 that is projected on the application surface 19 is big more, the width of light beam that just reflects is bigger, its light intensity relatively a little less than.If meet the environment that light reflects bad or easy scattering, when for example on glass isolator or too bright 's desktop, working, because the background light of environment is stronger, and the beam area A1 that is projected to application surface 19 is big and a little less than making light intensity that optical mouse 10 received, the optical mouse 10 this moment situations of erroneous judgement application surface 19 concavo-convex inequalities easily.
Hence one can see that, and the light intensity of optical mouse 10 light that receives can influence its sensitivity, and the light intensity size is relevant with width of light beam or beam area, and width of light beam is more little or beam area is more little, and then light intensity is big more.Therefore need a kind of method that promotes spotlight effect, to promote the sensitivity of optical mouse 10.

Embodiment
See also Fig. 2, Fig. 2 is the synoptic diagram of optical mouse 20 of the present invention.Optical mouse 20 comprises a light source 11, lens 13, a reflecting surface 15, an arc surface 22, a penetration surface 14 and an optical sensor 17.Light source 11 is used for throw light, and convex lens 13 are in order to light focusing, and reflecting surface 15, arc surface 22 and penetration surface 14 be in order to leaded light, with ray guidance that light source 11 is produced to application surface 19.And the light that optical sensor 17 reception application surfaces 19 are reflected is with the running of control optical mouse 20.
As the light path among Fig. 2, light source 11 projects light, and this light forms a light beam via the effect of convex lens 13 earlier, and directive reflecting surface 15.Then, the light beam of directive reflecting surface 15 marches to arc surface 22 downwards through the reflex of reflecting surface 15, and the light beam in this moment prism is identical with known beam path (Fig. 1), and the intensity of light beam is also identical with width.Yet, after the reflex via arc surface 22, the integrated narrower light beam of beam convergence of originally advancing, as among Fig. 2 through shown in arc surface 22 beam reflected, meaning light intensity increases.Last this gathered light is projected on the application surface 19 again via the refraction action of penetration surface 14.
Light path in Fig. 1, the arc surface 22 of Fig. 2 can be gathered into narrower light beam with the light beam that originally advances in the prism, utilizes the mode of assembling light beam strengthening light intensity, to remedy in prism the problem that causes light intensity to weaken through twice reflex.In addition, because the light beam in the prism has been gathered into narrower light beam, this light beam reflects via penetration surface 14 again, and its beam area A2 is less compared to the beam area A1 among Fig. 1, and just the light intensity of optical mouse 20 light that receives is stronger among Fig. 2.
