DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a light guide and a lighting device including a light guide. The light guide is suitable for color mixing in order to obtain a homogeneous or heterogeneous color mixture. In particular, the invention relates to illumination, such as stage lighting or store lighting. [Prior Art] It is known that a light guide is integrated into a light guide comprising a light-emitting diode (LED) as a light source, a light collector, a collimator and a reflector. The concentrator is disposed around the LED dome at the light entrance of the light guide to achieve a high collection of light emitted by the LED. The collimator and the reflector are disposed at an exit of the light guide. Perfect alignment of the various components of the luminaire is necessary. SUMMARY OF THE INVENTION One object of embodiments of the present invention is to provide a light guide and an illumination device including the same, wherein the method for manufacturing the light guide and the illumination device is facilitated and simplified. Another object of embodiments of the present invention is to provide an illumination device having an improved light output/light input ratio. To this end, an embodiment of the present invention provides a hollow light guide comprising a conduit and an outlet portion, the light guide having a wall, the inner surface of the wall comprising a light reflective material, wherein the outlet portion is from a first end to a The second end is outwardly wedge-shaped, and wherein one end of the conduit is the first end of the outlet portion. The invention also proposes a device comprising a hollow light guide and at least one light source disposed at the other end of the conduit. 127353.doc -6 - 200839150 According to this embodiment, the conduit and the outlet portion of the light guide are fabricated in a unitary form. Therefore, it is not necessary to align a conduit separate from an outlet portion to ensure an acceptable light guide. Furthermore, the light guide is hollow. This has at least two advantages when it comes to making a lighting device. First, the light guide can be easily configured around a light source, particularly when the light source is not flat. The first 'does not have to fit and align a light collector between a light source and the light guide. In one embodiment of the invention, the wall of the hollow light guide is comprised of an assembly of at least two longitudinal wall elements that exhibit at least an equi-angular symmetry therebetween. One advantage of this embodiment is that the same seed elements can be easily stacked together. This allows for the storage and transport of compact sub-components, such as when manufacturing sub-elements and their assemblies to produce hollow light guides that are not in the same location, and in the case where the light-reflecting material is deposited on the wall, there are a plurality of The wall element simplifies the deposition process. In another embodiment, the hollow light guide conduit includes a first tube that forms an angle with a second tube at a curved section. To achieve proper color mixing when the light guide is used with a source of light having a different spectrum, a relatively long catheter may be required. The length of the catheter depends on the cross section of the catheter or depends on the light source. (4) It is too long to be troublesome in installing the lighting device (for example, on the wall, under a ceiling, in a lattice ceiling, or in a suspended day palladium plate). One of the advantages of providing a curved hollow light guide is its improved and tightness of the illumination device of the curved hollow light guide. In another embodiment, the catheter comprises a light diffusing element. This improved color mixing when the light guide is used with a source of light having a different spectrum. When the cover is homogeneously mixed, the light diffusing element has in particular n hollow light guides. 127353.doc -7- 200839150 In an embodiment comprising a curved section, the curved section may comprise a light diffusing element. Depending on the cross section, a homogeneous or heterogeneous color mixture can be achieved. Square, hexagonal or rectangular cross sections are preferred when it comes to homogenous color mixing. It is preferred to include a heterogeneous color mixing 4' circular or pentagonal cross section.
在本發明之一實施例中，一照明裝置較佳包含至少兩個 光源，每一光源容許發射一特定光譜，使得至少兩個不同 光譜可用。因此，在光導之入口處發射不同光譜。此等光 譜在光導中組合在一起且在光導之出口處獲得_經組合之 光譜。此經組合之光譜可認為由在光導之入口處發射之個 別光譜之疊加所產生。換言之，色彩混合可在本發明之該 實施例中達成。 本發明之實施例亦提議一種製造一中空光導之方法，豆 包含： ^ 提供具有一凸壁的至少兩個等角子元件，每一子元件包 含一導管扇形及一出口扇形，其中該出口扇形自一第一末 端至一第二末端向外成楔形，且其中該導管扇形之一末端 為該出口扇形之該第一末端， 用一光反射材料塗佈每一凸壁之内表面的至少一部分， 將該等子元件裝配在一起以形成一包含一導管及一2口 部分並具有一壁的中空光導， 該導管可具備一光漫射元件。 在該方法之一實施例中，提供待裝配在一起之兩個子元 件且該等子元件在自身之間相對於—對稱平面為對稱的。 127353.doc 200839150 因此，對應於導管及出π部分扇形之料子元件具有一為 兀弧度之角度。此組態在各種目標之間（即，在以下目標之 中）達成-滿意平衡：易於製造該等子元件、易於處理及 裝配該等子元件、緊密儲存該等子元件。 參考下文所述之實施例，本發明之此等及其他態樣將顯 而易見並得以闌明。 【實施方式】 以下定義採用於本說明書中。In one embodiment of the invention, an illumination device preferably includes at least two light sources, each of which is capable of emitting a particular spectrum such that at least two different spectra are available. Therefore, different spectra are emitted at the entrance of the light guide. These spectra are combined in a light guide and a combined spectrum is obtained at the exit of the light guide. This combined spectrum can be thought of as being produced by the superposition of individual spectra emitted at the entrance of the light guide. In other words, color mixing can be achieved in this embodiment of the invention. Embodiments of the present invention also provide a method of fabricating a hollow light guide, the bean comprising: ^ providing at least two equiangular sub-elements having a convex wall, each sub-element comprising a duct fan and an exit fan shape, wherein the exit fan shape a first end to a second end outwardly wedge-shaped, and wherein one end of the duct fan is the first end of the outlet fan shape, and at least a portion of the inner surface of each convex wall is coated with a light reflective material, The sub-elements are assembled together to form a hollow light guide comprising a conduit and a 2-port portion and having a wall, the conduit being provided with a light diffusing element. In one embodiment of the method, two sub-elements to be assembled together are provided and the sub-elements are symmetrical about themselves with respect to a plane of symmetry. 127353.doc 200839150 Therefore, the material element corresponding to the catheter and the π-part fan has an angle of curvature of 。. This configuration is achieved between various targets (i.e., among the following objectives) - a satisfactory balance: ease of manufacture of the sub-elements, ease of handling and assembly of the sub-elements, and close storage of the sub-elements. These and other aspects of the invention will be apparent from and elucidated with reference to the appended claims. [Embodiment] The following definitions are used in the present specification.

In a plane, 'central symmetry (symmetric with respect to _ point) is equivalent to a rotation angle. Fan opening is understood to be any angle greater than 〇 radians and below 2π solitude. & is a basic element comprising a hollow straight cylinder made of a rigid or flexible material. A "catheter" is a tube that has been given a specific shape and/or has been assembled to a connection and/or other tube. 1 and 3 depict a hollow light guide in accordance with a first embodiment of the present invention. Zhonggongguang V 101 includes a conduit 102 and an outlet portion 1〇3. The catheter 1〇2 has a first end and a second end 122 that coincides with a first end 131 of the outlet portion 103. The outlet portion 1〇3 is a light shielding and reflector member. The outlet portion 1〇3 is wedge-shaped outwardly from the first end 131 to a first end 132. It may have various spherical shapes such as a spherical shape, a parabolic shape, and a tapered shape. 127353.doc 200839150 In this embodiment, the hollow light guide 101 is comprised of two identical wall elements 1〇la and 101b along their longitudinal edges 115 and 116, along the assembly line 101〇. The sub-elements 101 & and 1 〇 11) respectively include duct sectors 102 & and 1 〇 21}, and respectively include outlet sectors l 〇 3a and 103b. The sub-elements 1〇1& and 1〇lb represent the longitudinal half of the hollow light guide 101. Each subcomponent is manufactured in a unitary form. The longitudinal section of the hollow light guide of Fig. 1 along the assembly line 1〇lc is illustrated in Fig. 3. The wall 113 of the light guide 101 comprises a wall 123 of the conduit 1〇2 and a wall 133 of the outlet portion 1〇3. The inner surface 114 of the wall 113 contains a light reflective material. The light reflecting material may be composed of a coating applied to the inner surface 114 of the niche 3. Wall H3 can also be made of a light reflective material or comprise a light reflective material. Preferably, the light-reflecting material is a surface coating or a silver coating having a dielectric reinforcing effect or a dielectric coating. The sub-element 101a and the sub-element 101b can be assembled with various assembly members. For example, & ' can apply a layer of glue along the longitudinal edges of each of the sub-components 〇丨 & and 丨〇ib. It is also possible to provide a sleeve or a loop (not illustrated) around the catheter 1〇2 (eg, near the first end 121 of the catheter ι〇2). The inner surface of the sleeve or ring engages the outer surface 117 of the conduit 1〇2. In another embodiment, a rubber band (not illustrated) or a plurality of rubber bands can be used as the assembly member surrounding the catheter 1〇2. For example, a rubber band can be used near the first end 121 of the catheter 102 and another rubber ring can be used near the second end 122 of the catheter 1〇2. In another embodiment of the assembly member, the edge 115 of the sub-element 1〇1a has a slider that can be received in a recess provided in the edge 116 of the sub-element 101b. At the same time, the edge 115 of the sub-element 1〇1b has a sliding tongue' which can be received in a recess 127353.doc 200839150 slot provided in the edge 116 of the sub-element 1〇1a. Thus, the positioning of the sub-elements 1& and lb relative to one another can be achieved. As appropriate, the assembly members can be combined without limitation. Figure 5 shows a lighting device incorporating a hollow light guide in accordance with the first embodiment (Figures 1 and 3) of the present invention. The hollow light guide 101 is disposed around the light source 104 fixed to a support 105. Light source 104 can include an incandescent lamp or a light emitting diode (LED). The support 105 contains an electrical connection for the power source of the light source 1〇4. In this embodiment, a photometric element 106 is fitted into the catheter 1〇2. To facilitate the configuration of the light guide 101 around the light source 104, the first end i 2 of the catheter 102 can be provided with an outwardly extending ear (not illustrated), for example, with an inwardly extending ear or Cooperate with the ring provided on the support 1〇5 of the light source 104. The illumination device can include a plurality of light sources. Each source allows for the emission of a particular spectrum such that at least two different spectra are available. In this case, the illumination device can be used for color mixing. Each light source has a specific spectrum. The resulting spectrum can be controlled by carefully selecting a set of spectra and depending on which source is illuminated. In a preferred embodiment, the illumination device comprises four lEDs, each of which has one of the following spectra: white, red, green, and blue, vJ1, green, and blue are basic colors, which are widely used. (for example, used in TV screens) to produce a complete color palette of visible colors (for the human eye). It is also possible to select other spectra than those mentioned above, or to combine only one, two or three of these types of LEDs. Using white, red, green, and blue LEDs, you can see which LED is turned on and which LED is cut to get a large set of colors. Circuitry for turning any of the given LEDs on or off is well known, and it is also well known to provide any combination of LEDs required for color in the visible spectrum. 127353.doc -11 - 200839150. 2 and 4 show a hollow light guide in accordance with a second embodiment of the present invention. Fig. 6 shows an illumination device which does not include the hollow light guide of the second embodiment of the present invention. The main difference between the first embodiment and the second embodiment of the hollow light guide is that in the second embodiment, the conduit 202 includes a first tube 224, and the first tube 224 and a second tube 225 are in a curved section. An angle is formed at 226. The inner surface 214 of the wall 213 can include a light diffusing element 207 at the curved section 226. Most of the light entering the hollow light guide 2〇1 will interact with the inner surface 214 of the wall 213 at the segment 226. Therefore, most of the light entering the hollow light guide j will interact with the light diffusing elements 2〇7. This improved color mixing occurs when the light guide is used with a light source having a different spectrum while using a light having a limited surface. It is also possible to fit a photometric element in the conduit 2〇2: in the first tube 224, in the second tube 225 or in both tubes. It is advantageous to provide a curved conduit 202 because it allows the catheter to be longer and less troublesome than the straight conduit 1〇2. Since the color mixing quality depends on the length of the catheter, it may be necessary to use a curved catheter when the available space for installing the lighting device is too small for a straight conduit. Other features of the hollow light guide and illumination device according to the second embodiment of the present invention are similar to the corresponding features of the first embodiment. Color mixing occurs in the catheter 2. Among other parameters, the homogeneous or heterogeneous color mixture depends on the length of the catheter and the cross-section of the catheter. When the spectrum observed by the naked eye looks uniform at the second end 132 of the exit portion 103, the color mixing is considered to be homogeneous. When the timing of the spectrum observed on the exit plane is observed at the second end 127353.d〇c -12- 200839150 132 of the exit portion 1〇3, the color mixing is considered to be different. It can be realized by projecting on a self-color screen that it is found that mirror-tiling uniformly fills the shape of a region (the shape of the cross-section of the catheter) to provide good homogeneity. For example, a square, hexagonal or rectangular cross section generally provides a homogeneous color blend, while a circular or pentagonal cross section typically provides a heterogeneous color blend. In addition, longer catheters provide a more homogeneous color mixture than shorter catheters. In the embodiment of Figure 1, the conduit has a regular hexagonal cross-section, as illustrated in Figure 7a. However, the scope of the invention is not limited to the embodiment. Other cross sections are also conceivable 'such as those shown in Figures 7e through 7m. Moreover, Figures 7a through 7d illustrate various possibilities with respect to the number of equiangular subelements that are assembled to form a hollow lightguide in accordance with the present invention. In Figures 7a to 7m, the sub-elements are separated by an indented Hne and are identified by reference numerals 2a, 2b, 2c and 2d. The hollow light guide is shown in Figures 7a to 7d, the conduit of which has a regular hexagonal cross section. In Figure 7a and Figure, the hollow light guide is the assembly of two symmetrical sub-elements. In these examples, the wall elements represent - π sectors. In Figures 7c and 7d, the hollow light guide is an assembly of three symmetrical sub-elements. In these examples, the wall elements represent a 2π/3 sector. In Figure 7a and Figure, the assembly line passes through the top of the hexagonal conduit. In Figures 7b and 7d+, the assembly line passes through the sides of the hexagonal conduit. Figures 7e and 7f show a hollow light guide having a square cross section and a light guide of 127353.doc -13 - 200839150 as an assembly of two symmetrical sub-elements. Figures 7g through 7i show an assembly of hollow light ''the conduit having a rectangular cross section and the hollow light guide being two symmetrical sub-elements. In these examples, the wall (four) represents a _π sector. In Figures 7f and 7i, the assembly line passes through the top of a square or rectangular conduit. In Figures 7e, 7g and 7hlj?, the assembly line passes through the sides of a square or rectangular conduit.
