Description of the Invention: [Technical Field] [0001] The present invention relates to a light guiding device and a light guiding method for a light emitting system of an LED module; in particular, a composite design of a light guiding device The means by which the radiation of light produces a more desirable output configuration between the light guiding means. [Prior Art] [0002] Application of an optical lens or structure, such as a total reflection (TIR) optical structure, refraction-reflection-total reflection (RXI), short-focus type:: optical structure, allowing a light source (such as an LED light-emitting chip) to emit The collimator of the light emitted parallel to each other is already known as a squeak. In general, such optical lenses or light-extracting devices can be used in applications such as 8M indications, projections or similar flashlights; basically, they include a reflector or reflector with a conical or bowl-shaped profile for receiving light. The light is emitted and the light guide is reflected out. As those familiar with the art know, some short-focus refracting acoustics, (five) syllabic uniformity _ is poor, and reflective optical structures are larger angles (for example, 20~45 广 breadth) The light cannot be directed into the phase X parallel parallel mode output. Basically, the pattern in which the rays are parallel to each other is defined as the divergence angle of the light, based on a reference axis, within ±8°. [0003] Please refer to Figures 1, 1 to 1, in order to improve the optical efficiency problem, the prior art has also revealed an improved structure; for example, U.S. Patent No. 6,547,423, 62, "1^0 (:01^11^ The 1'101^0?1'108 WITH IMPROVED PERFORMANCE AND REDUCED SIZEj patent case provides a typical embodiment. It is in the form of a bowl 099128530 Form No. A0101 Page 3 / Total 38 Page 0992050105-0 201209347 The solid optical lens or element a is provided with an alcove b; the recess b is combined with a light source c. This embodiment is designed by the geometrical contour of the structure of the recess b to obtain control of the refraction of light into the optical element a. The angle, which is reflected by the inner surface a 1 of the optical element a, reflects the parallel output of the light. [0004] [0005] In the "LED COLLIMATOR HAVING SPLINE SURFACES AND RELATED METHODS" patent publication No. 2009/01 28921 A1, it is also disclosed A solid optical lens or element d using a bowl-shaped profile is provided with an alcove e, which combines the technical means of a light source c; for example, the situation shown in Figures 2 and 2-1. Features of the embodiment in The optical element d is composed of different segments d 1 , d 2 , d 3 , etc.; with a Bezier curve and a tangent intersection obtained for each segment d 1 , d 2 , d 3 , Adjusting the curvature of each segment dI, d2, d3, so that each segment d1, d2, d3 reflects light, each light can form a parallel type output. It can be understood that the above reference considerations It is the subject of "optical path"; that is, how to make the path of light travel in parallel. They do not consider the problem of "light intensity" or "illuminance uniformity." Please refer to Figures 3 and 4 for details. The distribution of the light reflection intensity of the lam- bertian surface. Assuming that the LED light source is the blue reflecting surface, the reflected light k 1 is at 0 ° (or the χ axis in the figure), and its light intensity is about 100%; reflected light k 2 at a position of 30°, its light intensity is only 87%; reflected light k 3 at 60 °, its light intensity is only about 50%. At the same time, we also define 099128530 form number A0101 Page 4 of 38 Page 0992050105-0 201209347 The light k 1 For strong light; light k 3 is weak light. [0006] Ο [0007] ❹ However, as those familiar with the art know, the above references (including US 6, 547, 423 B2, US 2009/0128921 A1) There is a problem of uneven illumination. Please refer to the first and second graphs and the first and second graphs 1-2 according to the light intensity distribution and the light distribution curve. It can be understood that the illuminance distribution emitted by the light source c sequentially causes the strong ray k 1 to be disposed in the target region T. The intermediate region T1; the weak ray k 3 is disposed on the sub-region τ 2 of the target region τ of the intermediate region T1 of the adjacent strong ray k1; the ray k 2 is disposed at the target of the adjacent weak ray k 3 sub-region T 2 The area T of the area T is on the periphery. This illuminance distribution in the target zone τ is not ideal; please refer to the 1st - 1st, 2nd - 1st diagram, because 'weak light k 3 is arranged in the dawn, between the line and the k 2, causing the vice The light intensity or illuminance of the region T 2 is weaker than the peripheral region τ 3 , so that the illuminance unevenness of the aura or the dark band and the efficiency of the luminescent wafer cannot be improved in the entire target region, which is not desirable. Representatively, 'the reference system shows the application of light source and light guides in application; we also reflect the design of these light guides in some applications, some problems exist if the design is re-designed Considering the organization of the light guide so that its structure* is the same as that of the learner, it will change its use type, which is different from the old one; in fact, it will increase its dependence. But how do you overcome or improve the shortcomings we discussed above? For example, the structure design of '(4) is in accordance with a simple condition, and has the function of redirecting the light guide, etc., and further increases the distribution of the illuminance, and improves the conventional structure to produce a degree of unevenness We found its construction 099128530 Form number Α0101 Page 5 of 38201209347 The following design issues must be considered: [0008] [0009] h should be different from the above reference materials (including US 6,547,423 B2, _〇 9/_921 A1) Considering the "light path, the structural organization and design direction; and the system" for the "illumination uniform sentence," the question is considered 〇 2. In order to obtain the "illumination, the role of the light guide device The internal structure should be rearranged and designed. If considering this angle, the light guide device is ideally designed. In the distribution of optical illumination, the strong light should be guided and outputted, and then placed in the target area T. The intermediate region T1; after the weak ray k 3 is guided and output, is disposed in the peripheral region T3 ′ where the target region τ is less important, so that the optical efficiency of the whole is as much as possible However, these problems are not taught or specifically disclosed in the above reference materials. [Invention] The main object of the present invention is to provide a light guiding device and a light guiding method for a light emitting system, which are provided for manufacturing. And the structure is simple, and improving the optical illuminance of the conventional structure, affecting the illuminating effect, etc.; comprising a first light guide combined with a light source and a second light guide. The first and second light guides respectively comprise a reflecting surface, wherein at least a portion of the reflective inner curved surface has a focal point (point), such that the first and second light guides form a confocal point (point) or a substantially confocal shape within a range. A light guide receives at least a portion of the light of the light source such that they pass through the focal (dot) region or the confocal (dot) region, and then illuminate the reflection to the second light guide. 099128530 Form No. A0101 Page 6 of 38 0992050105-0 201209347 The output on the inner curved surface, in order to change the configuration of the illumination of the light source, to improve the illumination effect in the old method, etc. [0010] The light guiding device of the light emitting system according to the present invention, the first The reflecting surface of the optical device forms an elliptical (profile) profile with a reference axis, and has a first focal point (point) region and a second focal point (dot) region, and the light source is disposed at the first And a light aperture (or aperture) formed at least in the first focal (dot) region. The reflective surface of the second light guide forms a bowl-like contour with the reference axis or Parabolic (section) profile, with a focal (dot) region and an entrance aperture (or aperture) formed in the focal (dot) region; said second light guide focus (point) The zone forms a confocal (point) with the ¥-spot (dot) zone of the first illuminator or a substantially confocal type in a range. [0011] According to the light guiding device of the light emitting system of the present invention, the first light guiding device forms a light transmissive solid body; and the reflecting surface of the first light guiding device is coupled to the first light guiding device表面f .丨.Γ . - : ' Ί #

The first and second graphs show that the light 3 3, 3 2, 3 3 passes through the optical action of the first light guide 1 〇 and the secondary optics of the optical elements 3 and d, forcing the light 3 1 3, 3 3, depending on the intensity of the illuminance, respectively, are arranged in the middle area T1 of the target area T, the sub-area 099128530, the form number A0101, page 15 / 38 pages 0992050105-0 201209347 - #peripheral area T3; this helps to make the illuminance Obtaining the distribution of both "^4US 6,547,423 B2^US 2009/0128921 to form the light intensity or illuminance of the region T 2 is weaker than the surrounding region τ 3 'to make the entire target region 光 produce halo or dark band illuminance unevenness and luminescence The case where the wafer efficiency is low. [0037] Referring to FIG. 1 4 '', an embodiment (a schematic perspective view of a structure of a light guiding device) derived from one of the light guiding devices of the present invention is depicted. The figure shows a cross-section of the first light guide 1 〇 and the second light guide 2 另一个 in another direction, a square or rectangular shape. If the first light guide and the second light guide 20 are solid body knotting machines, the interface connecting the foods can be selected from the same material or the material close to the refractive wire is composed of 1 towel imaginary line injury system is not visible. The two light guides 20 configure the position and type of the secondary concentrating element 4 , to adjust the exit angle of the outgoing light in the central area. In another derivative consideration, the first light guide 10 or the reflective surface ii (or the first light guide 20 or the reflective surface 21) may be composed of a plurality of planes or curved surfaces; for example, four or A plurality of p-shaped planes or four square planes together form a complete reflective inner (curved) surface. Further considering the above embodiment, it is assumed that the first focal zone 1 3 a of the first light guide 丄〇 is substantially confocal (or slightly confocal) within a range of the second light guide focal zone 23 3 . Or forming a distance between the first focal region 13 of the first light guide and the focal spot 23 of the second light guide. For example, if the first focal zone 1 3 a is below the focal zone 2 3 or the first focal zone 1 3 a is above the focal zone 23, the path of the rays 3 2, 3 3 should be generated. Some changes make the light out of the light form a state of convergence or divergence. 099128530 Form No. A0101 Page 16 of 38 0992050105-0 201209347 [0038] Basically, the above defocused configuration can be set according to the actual design needs. The position of the second light guide focal zone 23 relative to the first focal zone 1 3 a of the first light guide 10 may be at the first light guide light exit aperture 1 4 (or the second light guide 20 The aperture of the aperture aperture 2 4) is shifted. That is to say, according to the uniformity of illumination, the two focal zones may be confocal or substantially confocal in a range, and the preferred positional consideration is within the radius of the confocal aperture, ie, the exit aperture 1 4 or within the radius of the aperture 2 4 . [0039] ft Referring to Figures 15 and 16, another deriving embodiment is depicted; the light guiding means of the first light guide 10 and the second light guide 20 are combined to form a plurality of guides at a spaced distance. The type of arrangement of the light devices. Fig. 16 also shows that each of the light guiding devices forms an interconnected pattern. The imaginary line portion in the figure shows that each light guiding device can be connected to each other via a plane. [0040] ❹ Referring to FIGS. 7 and 18, another deriving embodiment is depicted; the light guiding device combined with the first light guide 10 and the second light guide 20 forms a plurality of spaced apart distances. The array pattern of light guiding devices arranged; in this embodiment, the array pattern is a hexagonal array structure. Figure 18 also shows that each light guiding device forms an interconnected array pattern. [0041] Representatively, the light guiding device and the light guiding method of the light emitting system include the following design considerations under the condition of providing a structural simplification: [0042] 1. Making the first light guide 10 Primary optical action and second light guide 2 099128530 Form No. A0101 Page 17 of 38 0992050105-0 201209347 The structural organization of the secondary optical action of 〇 is considered for the subject of “illumination”. Different from the above reference materials (including US 6,547,423 B2, US2009/01 28921 Α1) Consider the structural organization and design direction of ''optical path'. 2) In order to obtain the effect of "illuminance uniformity", the internal structure of the light guiding device It is re-listened and designed; the system is that the reflecting surface 11 of the first light guide i 系 is established - an elliptical curved contour profile, and has a first focal zone l3a and a second focal zone 13b, so that the light 3 1 3, 3 3, after an optical action, through the focal (point) zone or the confocal (point) zone, forcing the strong light 3 1 to be guided and output, and then arranged in the middle zone of the target zone τ After the weak light 3 3 is guided and output, In the case of setting the target area is less important Ding Ding surrounding area 3. Considering this angle, compared with the old method, this light guiding device is an ideal design, not only in the optical illuminance:::; coupled, more uniform, and the overall optical efficiency is as much as possible Improvement. Therefore, the present invention provides an effective light-emitting device light guiding device and a light guiding method; the spatial pattern is different from the conventional one, and has the functions not in the old method, and obviously shows a considerable amount. progress.
