Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
A kind of light conducting member that the embodiment of the invention provides can be used for the electronic equipment with distant control function, on electrical equipment such as televisor, TV set-top box, projector or Other Instruments equipment, to increase the remote-controlled angle of electronic equipment; Also can be used on the electronic equipment of tape light, with the light refraction of pilot lamp to panel.
Like Fig. 2~shown in Figure 6; Above-mentioned light conducting member 100 can adopt PMMA (Poly methylMethacrylate; Polymethylmethacrylate; Also be acrylic or organic glass), ABS (AcrylonitrileButadiene Styrene, acrylonitrile-butadiene-styrene copolymer) or SAN printing opacities such as (styrene-acrylonitrile copolymers) and refractive index process (refractive index refers to the light phase velocity in a vacuum and the ratio of the phase velocity of light in medium) greater than 1 material.In the present embodiment, above-mentioned light conducting member is applied on the STB of televisor, to illustrate the beneficial effect of the embodiment of the invention.Offer indent on the end face of one end of said light conducting member 100 and have the sensitive surface 101 of the conical surface, offer the exiting surface 102 of indent on the end face of the other end of said light conducting member 100.Light conducting member 100 is used for receiving incident lights from sensitive surface 101, and after said incident light reflected or reflect, said incident light is penetrated from said exiting surface 102.Said sensitive surface 101 is used to receive incident light and incident light is reflected on sensitive surface 101 and/or reflects, and exiting surface 102 is used for the incident lights in the light conducting member 100 are reflected outside the light conducting member 100.In the present embodiment, light conducting member 100 is cylindric, and perhaps, light conducting member 100 also can wait suitable shape in the form of sheets, all belongs to protection scope of the present invention.Sensitive surface 101 is arranged at the upper end of light conducting member 100; The lower end that exiting surface 102 is arranged at light conducting member 100 (it is to be noted; This paper indication " upper end " and " lower end " be relative concept each other, in actual use, might not " upper end " up; " lower end " down), sidewall 105 is the periphery wall of light conducting member 100.
Further; Like Fig. 3 and shown in Figure 4, light conducting member 100 is provided with an end of exiting surface 101, and arranged outside has conical surface section 103; Away from said sensitive surface 101 directions, the cross-sectional area of conical surface section 103 dwindles gradually on the light conducting member 100 along light conducting member 100 axis.
Sensitive surface 101 can be the conical surface shape that concaves or inclined plane shape etc., and in the present embodiment, sensitive surface 101 is taper.Preferably, the cone angle that the conical surface forms in the sensitive surface 101 is the twice of the cirtical angle of total reflection of said light conducting member 100, the angle that two conical surfaces of the sensitive surface 101 that the cone angle of the conical surface refers in the sensitive surface 101 form.When light gets into optically thinner medium by optically denser medium, leave the normal refraction, when incident angle θ was increased to certain situation, refracted ray prolonged the surface and carries out, and promptly the refraction angle is 90 °, and this incident angle θ is called the cirtical angle of total reflection.If incident angle greater than the cirtical angle of total reflection, does not then have refraction, all light all returns optically denser medium, and this phenomenon is called total reflection.If light conducting member 100 adopts transparent PMMA material, its refractive index is about 1.49, and the cirtical angle of total reflection is 42 degree, and the cone angle of the conical surface can be set to the twice of the cirtical angle of total reflection, and promptly 84 spend, and the angle between sensitive surface 101 and the front panel is 48 degree.The sensitive surface 101 that has a conical surface is mainly used in that little (for example: the angle between the front panel normal of infrared light that telepilot sends and STB is less than a half of the cone angle of the conical surface in the sensitive surface 101 with incident angle (incident angle of this section refers to the angle between the front panel normal of infrared light that telepilot sends and STB); Be that 48 degree are example still with cone angle; Half of the cone angle of the conical surface is 42 degree in the sensitive surface 101) infrared light be incident upon exiting surface 102; Incident angle mainly contains following several kinds of paths less than the infrared light of 42 degree, and first kind of path is that (for example the infrared light among Fig. 3 a) through sensitive surface 101 refraction back arrival exiting surfaces 102 for infrared light; Second kind of path is that infrared light arrives exiting surface 102 (for example infrared light c among Fig. 3 and the infrared light k among Fig. 5) through side 105 reflections after face 101 refractions; To be infrared light after sensitive surface 101 refractions through conical surface section 103 reflex to sensitive surface 102 (for example infrared light b among Fig. 3 and infrared light j, the l among Fig. 5) in the third path; The 4th kind of path is that infrared light reflects back directive sidewalls 105 through sensitive surface 101, reflexes to conical surface section 103 then, and reflexes to exiting surface 102 (the for example infrared light i among Fig. 5) at conical surface section 103 places.The infrared light of incident is direct directive exiting surface 102 or the sidewall 105 of directive light conducting member 100 or conical surface section 103, and its position with the refractive index of the diameter of the slanted angle of sensitive surface 101, light conducting member 100, length, light conducting member 100 and incidence point is relevant.In general, if use the PMMA material, its cirtical angle of total reflection is about 42 degree, and general incident angle is less than the infrared light of 42 degree, and what play a major role is sensitive surface 101, and when incident angle was spent greater than 42, what play a major role was sidewall 105 and sensitive surface 101 inboards.Still penetrate light with Fig. 3 to Fig. 5 mid-infrared light incident direction is roughly consistent, can on sensitive surface 101, reflect and directive exiting surface 102 after sidewall 105 or the reflection of conical surface section 103 places at sensitive surface 101 diverse locations.
Like Fig. 2~shown in Figure 6, the cross-sectional area that sensitive surface 101 receives infrared lights is big, the horizontal interfacial area that infrared light contacts with sensitive surface 101 greatly and have the function of optically focused, even the increase of remote control angle, the distance of remote control can not shorten yet.Offer the exiting surface 102 of indent on the end face of the other end of said light conducting member 100, infrared light is arrived more easily receive a sensitizing range of 200, under the equal situation of telepilot emissive power, be beneficial to distance that prolongs remote control and the sensitivity that improves remote control.
When the infrared light directive sensitive surface 101 of telepilot emission, sensitive surface 101 can be with the infrared light refraction to conical surface section 103 or refraction to exiting surface 102.And conical surface section 103 is set in light conducting member 100 sidewalls; Its objective is direction, so that infrared light converges (incident angle of this section refers to the angle between infrared light and the plane of incidence normal) to the place, sensitizing range of infrared receiving terminal 200 central authorities for the IR that changes directive exiting surface 102 edges.Like Fig. 3, shown in Figure 4, the angle between sensitive surface 101 and the front panel normal can make after sensitive surface 101 refractions to the most of exiting surface 102 that is totally reflected to of the infrared light of conical surface section 103 greater than the angle between conical surface section 103 and the front panel normal.Through conical surface section 103 is set, infrared light is converged to the place, sensitizing range of infrared receiving terminal 200 central authorities, be beneficial to and improve remote-controlled sensitivity and scope.Be convenient to user's use, and the infrared light loss is few, helps improving the distance of remote control.Further, also can be coated with the opaque reflectance coating of one deck, reflect from light conducting member 100 sidewalls to avoid infrared light through side at light conducting member 100.
Preferably, as shown in Figures 2 and 3, said exiting surface 102 is the dome shape or the suitable shapes such as parabolic shape or arc surfaced or dome shape of indent.
Please continue 3~Fig. 5 with reference to figure, the dotted line among Fig. 3~Fig. 5 is the path of incident, refraction and the reflection of infrared light.The situation of dividing two kinds of situation explanation infrared light directive light conducting members below: first kind of situation is directly directive sensitive surface 101 of the infrared light that sends of telepilot; Because sensitive surface 101 is the concavity of being with the conical surface; Incident angle (incident angle in this section refers to the angle between the front panel of infrared light that telepilot sends and STB) is less (for example; Less than 42 the degree) infrared light a will directly refract to exiting surface 102 places; As i among Fig. 3 mid-infrared light a, b, c and Fig. 5, j, k, l, the path shown in; These infrared lights all can refract to exiting surface 102 through sensitive surface 101 and sidewall 105 or conical surface section 103, and refract to infrared receiving terminal 200 places that are positioned at exiting surface 102 belows by the exiting surface that is concavity 102.
Second kind of situation; Like infrared light d, e, f, g, the h among Fig. 4; When the user is arranged in more inclined to one side angle (that is: the angle between the front panel normal of the infrared light that sends of telepilot and STB is greater than a half of the cone angle of sensitive surface 101 conical surfaces), the angle between the front panel of infrared light d, e, f, g, h and the STB of telepilot emission is less, and the infrared light d that telepilot sends, e, f, g, h be the sensitive surface 101 of directive indent directly; It can only reflect from the side of light conducting member 100 to sensitive surface 101 inboards; For example infrared light d, e, f, g, the h of incident, light d, e, f, g, the h of refraction will arrive the conical surface of sensitive surface 101, the phenomenon of infrared light generation total reflection from light conducting member 100 sides; The infrared light d of total reflection, e, f, g, the h exiting surface 102 that can go directly downwards; Perhaps reflex to sidewall 105 places of light conducting member 100, reflex to exiting surface 102 again, and refract to infrared receiving terminal 200 places that are positioned at exiting surface 102 belows by exiting surface 102.
Below from the condition of incidence of theoretical derivation infrared light:
Please refer to Figure 13, suppose that light conducting member 100 uses transparent PMMA (refractive index is 1.49) material, and the incident angle that hypothesis incides the left side of sensitive surface 101 is A, be B through sensitive surface 101 refraction angles, shown in figure 13;
1.49=sinA/sinB is then arranged,
The cirtical angle of total reflection that can obtain simultaneously the PMMA material is that b '=arcsin90/1.49 draws b '=42 degree, and the cone angle of sensitive surface 101 is got 2 times of the cirtical angle of total reflection, i.e. 84 degree;
If through the incident angle of the light behind the sensitive surface 101 on sidewall 105 is C, so want total reflections to take place then to need C>b ' promptly be C>42 degree in that sidewall 105 is inboard.Seeing has among Figure 13
90-b′=X+B,
X=90-C
So draw C=B+b ' by following formula, again because b ' is 42 degree,, then can derive so the C perseverance is spent greater than 42 as long as the B angle is correct time, the light that refracts to sidewall 105 from sensitive surface 101 all can produce the phenomenon of total reflection.
Please refer to Figure 14, suppose that from the incident angle of the light of side incident be A, is B through refraction angles, sidewall 105 back, and C is the incident angle C of inboard emission total reflection on the sensitive surface 101.Prove that at first the infrared light that shines from side can total reflection take place in sensitive surface 101 inboards.
Known D=42 degree, 0<A<42 degree has refractive index 1.49=sinA/sinB,
According to Figure 14, C=90-(180-(D+90+B)) gets C=B+D=42+B, so C>=42 degree are arranged, then is bound to take place total reflection in face 101 inboards.The maximal value of B depends on the maximum with A; Because 0<A<42 degree can obtain according to 1.49=sinA/sinB, the B maximum probably is 28 degree; So the scope of C is 42<C<70, total reflection can take place in sensitive surface 101 inboards in the provable infrared light that shines from side.
Suppose that A is the incident angle (42 degree) of maximum among Figure 14, then maximum refraction angle B can obtain and equal 30 degree, obtains the outer length OM (rib length is the length of L:OQ) that is exposed at the panel outside.
Can learn angle OKN=B+90=30+90=120 degree according to top reckoning, when injecting a little at M, ∠ OKN=∠ OMQ=120 degree, then ∠ OQM=180-D-∠ OMQ=180-42-120=18 degree.
If L is the length of OQ line among Figure 14, OM=L*sin (∠ OQM)/sin (∠ OQM+D)=L*sin18 degree/sin (18+42) degree=L*0.309/0.866=0.3568*L then; Be set to 0.3568*L (this is to be example with the PMMA material certainly so suggestion light conducting member 100 stretches out the length of set top box front panel part; Different refractivity; Its length is provided with difference, but all can draw the length of depths set top box front panel part according to above-mentioned thinking).
In sum, through such design, make the user also can pass through IR remote controller remote control STB in more inclined to one side angle; The angle that STB can receive remote control is big; Can reach more than 170 degree, even can reach 180 degree, solve a difficult problem of the prior art; The user can arbitrarily pass through the IR remote controller remote-controlled television set in the televisor visual range, use very convenient.Conical surface section 103 can be used for the infrared light of all directions in the light conducting member 100 is converged to exiting surface 102; Most of infrared light can be incident upon the sensitizing range of the front end of infrared receiving terminal 200; Avoided the outer dead band of half angular of infrared receiving terminal 200; Improve the sensitivity of remote control greatly, thereby prolonged the distance of remote control.Even when injecting light conducting member 100 perpendicular to the sidewall of light conducting member 100, infrared light can reflex to exiting surface 102 places by sensitive surface 101, thereby the angle of remote control is increased greatly and the distance of remote control is prolonged.
