Description of the Invention: [Technical Field of the Invention] The present invention relates generally to the field of lighting devices, and relates to a lighting device for providing an illumination pattern. [Prior Art] A lighting device (or lamp) that provides a patterned projection is now used in decorative lighting for ambient purposes. Such illuminations may, for example, comprise a light-emitting diode and a cover' that is configured to project an illumination map onto a surface 丨 such as a wall or a light cover. Coffee is a high-brightness point-like source and can be advantageously utilized to form a projection of a particular illumination (4) fairly compact light. However, illumination from such lamps is not suitable for normal (or functional!) months. Uniform illumination, for example for reading. To provide both ambient and general illumination, two types of lamps can be used, providing ambient illumination and one providing general illumination. However, the disadvantage is that this solution is more expensive and takes up space. Moreover, it may be desirable to move or switch the illumination pattern (or image) projected onto the surface. For example, us 2〇〇3/〇〇35〇92 discloses a light pattern projection system in which a transmissive LCD matrix display is provided as a patterned member. A dynamic pattern can be provided by controlling the pixels in the LCD display to be light transmissive or opaque. A disadvantage of this technique is that it is quite complicated and expensive. SUMMARY OF THE INVENTION The present invention has been made in view of the above considerations. The present invention is directed to 159509.doc 201224329. An improved alternative to the above-mentioned techniques and prior art. A switchable round case. More specifically, the present invention is directed to providing a lighting device having a function. A feature that is achieved by facilitating a lighting device. This and other objects of the present invention are characterized by an independent technical solution by the illumination device. The preferred embodiment is characterized by the subsidiary technical solution.

The illumination device includes a first light generating unit configured to provide a first illumination pattern, and a second light generation unit configured to provide a second illumination pattern. The second illumination pattern is complementary to the first illumination pattern: at least partially superimposed on the first illumination pattern. Further, (4) the light intensity of at least one of the light generating unit and the second light generating unit may be adjusted with respect to the light intensity of the other light generating unit. According to a second aspect of the present invention, a method of operating a lighting device is provided. In this method, a first illumination pattern and a second illumination pattern complementary to the first illumination pattern and at least partially superimposed on the first illumination pattern are further adjusted to adjust the first illumination pattern and the second illumination Light intensity of at least one of the patterns. The present invention is based on the concept of providing at least two illumination patterns that are complementary to one another, which means that one of the illumination patterns is a negative image of the other. In addition, the illumination patterns are at least partially superimposed, i.e., overlapped, on a surface onto which they can be projected. When the respective light intensities of the two light generating units are at different levels, the superposition of the first illumination pattern and the second illumination pattern will result in a single patterned projection at the surface, thereby providing a suitable example 159509.doc 201224329 A pattern pattern such as ambient lighting. When the light intensities of the two light generating units are at the same level (or nearly the same), the superposition of the first illumination pattern and the second illumination pattern results in a more uniform illumination, ie, no on the surface ( Or at least almost, and/or there is a pattern because the first illumination pattern is complete and fills the second illumination pattern, and vice versa. In this latter case, the illumination device provides suitable illumination, for example, or A functional mode of job lighting. The present invention is advantageous in that it provides a lighting device having a switchable patterning function. In particular, the illumination device can provide at least two application modes by adjusting the light intensity of at least one of the light generating units; that is, the pattern mode and the functional mode (as defined above). The light intensity can be adjusted, for example, by switching the light-generating units to on or off, thereby switching between functional lighting (turning on two units) and ambient lighting (turning off the units: one) . In accordance with an embodiment of the present invention, a 豸 illumination & step-by-step includes a lance unit configured to control light intensity of at least one of the first light generating unit and the second light generating unit . The current embodiment is advantageous in that it allows at least one of the first generations to be controlled in a desired manner. For example, the = unit can allow the patterned projection to respond to the far-end signal, ‘allowing other desired modes to be controlled during the time loop. According to an embodiment of the present invention, at least one of the first light generating unit and the generating unit may be Yahoo T. Zhou Xian, which is advantageous in that the projection map 1 can be variably more or less " Contrast of the projections, and... The total illumination of the patterning from the U device can have a different light intensity of 159509.doc 201224329. In addition, if the two light generating units are dimmable, the illumination in the functional mode can also be dimmed, and the ratio between the light intensity of the first light generating unit and the second light generating unit 7L can be The adjustment is such that the first illumination pattern or the second illumination pattern can predominate on the patterned projection. The current embodiment is advantageous in that the illumination device provides a plurality of application modes. In accordance with an embodiment of the present invention, the first light generating unit can include a first light source associated with a first pattern projection optic (or first patterned member) to provide the first illumination pattern. Additionally, the second light generation C) unit can include a second light source 'which is associated with a second pattern projection optic (or second patterned member) to provide the second illumination pattern. In contrast to prior art based on, for example, an LCD matrix display, this implementation of the invention is advantageous in that it is relatively less complex. According to an embodiment of the invention, the illumination device may further comprise at least one mask 'equipped with a portion that allows light to be transmitted to provide the first pattern projection optics and the second pattern projection optics. When the mask is illuminated by a Q light source, an illumination pattern can be provided corresponding to the pattern formed by the configuration of the portions that permit light transmission. The mask may further include a portion that blocks light transmission and/or a portion that differs, for example, in color or light transmittance. The mask may have any size or geometry suitable for the purpose of the illumination device, and particularly for integration into the illumination device. The current embodiment is advantageous in facilitating the manufacture of the lighting device' and thus at a lower cost. Advantageously, the first source and the second source are symmetrical with respect to the mask. Therefore, the first illumination pattern provided by the first light source and the second illumination pattern provided by the second light source may be identical. If the light sources emit light at the same intensity as 159509.doc 201224329, the first illumination pattern and the first can be fully compensated (i.e., offset) from each other. According to an embodiment of the invention, the mask may separate a first area from a second area. The first light source may be disposed in a region, and the second light source may be disposed in the second region. Furthermore, at least one of the first side of the mask facing the first light source and the second side of the mask facing the second light source may be at least partially reflective (ie, the first One of the material materials on one or the second side may be at least partially reflective). In the current embodiment, for the light source facing the (at least partially) reflective side of the mask, an illumination pattern is by the reflective side of the mask (or a reflective portion on the side) The light is formed by reflection, and the other illumination pattern is formed by light transmission through the light transmitting portions of the mask. For the light source facing the non-reflective side of the mask, only an illumination pattern can be formed by the light transmission through the light transmissive portion of the mask by emitting light from the non-reflective side of the CMOS mask. The illumination pattern formed by the transmission of the light of light is complementary to the illumination pattern formed by the reflective side of the mask, the light source emitting t reflecting the light on the reflective side of the mask. The current embodiment is advantageous in that it provides a compact illumination device that provides a complementary illumination pattern. The respective intensities of the first source and the second source can then be controlled (adjusted) to provide multiple types of illumination (with or without a pattern, or with an enhanced or diminished contrast in the resulting pattern). The current embodiment is also advantageous in that the illumination patterns can be matched simultaneously in the near field and the far field, i.e., the illumination patterns can be matched at different distances from the illumination device because of the first and second illumination pattern sources. Since the same cover 159509.doc 201224329 cover. Thus, the illumination device according to the current embodiment can be adapted for use with a light cover and for use in a room where the walls are located at different distances from the illumination device. According to an embodiment of the invention, both the first side and the second side of the mask are at least partially reflective. One advantage of the current embodiment is that less light is absorbed by the mask when the illumination device is in a functional mode, i.e., when the light-generating units have the same (or nearly the same) light intensity. In other words, a larger portion of the light emitted by the light sources is output from the illumination device Ο. Thus, all or at least most of the light emitted from the sources is used to provide functional illumination and the efficiency of the illumination device is correspondingly improved. Furthermore, the use of a mask having two reflective sides is advantageous in that when the two light sources emit light at the same power level, both the first illumination pattern and the second illumination pattern can be switched off (ie, each other) Compensation), thereby resulting in a uniform illumination projection area. In addition, the light sources may be symmetrically placed with respect to the mask, which is advantageous in that when the illumination device is in the functional mode, one of the first illumination pattern and the second illumination pattern may be provided (or Offset ( thereby resulting in a uniformity in the projected area, which is derived from the superposition of the first illumination pattern and the second illumination pattern). Broken, if the light sources are disposed at symmetrical positions relative to the mask, the reflection provided by the reflection of light emitted from the first light source (eg, a light source disposed on the left hand side of the mask) The image (or illumination pattern) coincides with a transmission image (or illumination pattern) provided by the transmission of light from the second source (or a source disposed on the right hand side of the mask), and vice versa. 159509.doc 201224329 In accordance with an embodiment of the present invention, the illumination device can be multiplexed with a plurality of masks symmetrically arranged with each other, and a plurality of light sources between the masks: knives. For example, the illuminating device can be advanced to: a third mask and the like, such that the three masks are arranged in a two-figure diagram: the advantage is that it increases the possibility of constructing (four) the number of shots. Sexuality 'and thereby provide a greater change in lighting mode or should; The specific word can be defined - the third area,: a third light source can be placed. For example, if the light source is switched to on and switched to off, one can present a certain pattern and if the two sources switch to the second source to switch off, then another pattern can be presented. When all three sources have the same light intensity, no (or almost no) patterns are visible and provide a more even distribution of light. According to the embodiment of the present invention, the mask allows the portion of the money to be punctured into a periodic pattern. Further, the first light source and the second light source may be placed on the same side of the sea mask from one of about half of the period in the periodic pattern. The term "periodic pattern" can be interpreted as a linearly varying structure of alternating complementary patterns (e.g., alternating transmission and non-transmissive strips of a strange width). With this configuration, the lunar patterns provided by the two light sources can be complementary. An advantage of the current embodiment is that the light sources can be placed close to each other' which is preferably suitable for use in, for example, omnidirectional bulbs. Moreover, the illumination patterns can be matched well at different distances from the illumination device, especially for the far field. In the current embodiment, the complementary illumination pattern such as -Hay can be better matched (ie, 'overlapped" than the distance (distance) between the light sources, ie, especially greater than the light source 159509.doc - 10· 201224329 The distance between them is about ten times. According to an embodiment of the present invention, the illumination device may include a first mask 'equipped with a portion that allows light transmission to provide the first pattern projection optics (or first-patterning member)' and a second a mask that is equipped with a portion that allows light to be transmitted to provide the second pattern projection optics (or a second patterning structure), that is, the mask can be separated from the second mask, ie The first mask and the second mask may be two separate entities. In the illumination device, & means that the first mask is placed separately from the second mask. According to one embodiment of the present invention For example, the control unit can be configured to individually control any of the first light generating unit and the second light generating unit to enable the order to be switched on and off in an orderly manner. Accordingly, a visual effect can be provided. For example, a moving pattern. According to an embodiment of the invention, the light sources may be light emitting diodes (LEDs) and/or side emitting light emitting diodes. Because lEd is a (small) point light source, according to current implementation One of the lighting devices can be manufactured in close proximity and can be Improving the matching of the two illumination patterns. In addition, the efficiency of the illumination device can be improved because the LED is a highly efficient light source. The use of side emission lED is advantageous in that less light is aligned towards the projection optics other than the pattern. The outer direction 'by this further increases efficiency because all or at least a majority of the light from the LED is emitted from the illumination device. According to an embodiment of the invention, a light source can have a shield for obstructing light from the source The light is emitted in directions other than toward its associated pattern projection optics. The current embodiment is advantageous in preventing the emission of light from a source of light 159509.doc -11 201224329 in addition to projecting optics toward its associated pattern. The light in the other direction is (or directed to) the patterned projection thus being 'obstructed by a light source in other directions than the other toward its associated patterned member to avoid potentially degrading the projected pattern According to the present invention, at least one of the light sources may have a scattering exit diffusion n' to reduce the brightness of the light source. 'and smearing projection errors and alignment errors due to limited mask thickness. For two light source illumination devices comprising one of the masks with a periodic pattern and placed on the same side of the mask' or for inclusion of each other - illuminating means for the placement of a plurality of masks at the angle of the material and the light source placed between the masks, the use of a diffuser outlet diffuser is particularly advantageous. The use of a diffuser outlet diffuser is also advantageous in that it is more comfortable for the human eye to view the light source because The brightness of the light source is reduced. According to an embodiment of the invention, the mask may have a portion that has a dichroic filter.

The second light generating unit ii〇b further includes a second light source 1〇11) configured to illuminate a second pattern projection optics 1〇2b such that the second illumination pattern is provided in this document In the embodiment described with reference to Figures J a and 1 b, the β-first pattern projection optics 102a and the second pattern projection optics are two separate entities. Hereinafter, (4) - pattern projection optical fast means the first mask 102a, and the second pattern projection optical means the 159509.doc -13 - 201224329 second mask l〇2b. The first mask i〇2a and the second mask 1〇2b are respectively equipped with a portion that transmits light that allows light (and in particular, light emitted from its associated light sources 1〇1, 1〇11, respectively) to be transmitted. 104&, 1〇413. The first mask 1〇2& and the second mask 1〇2b may be further equipped with portions 105a, 105b' that block light transmission, respectively, or at least portions of the portions 1〇4a, 1〇4b that allow light to be transmitted. The light transmittance is different. The first illumination pattern and the second illumination pattern respectively provided by the first pattern projection optics and the second pattern projection optics are complementary such that they are each a negative image of each other. Furthermore, the light sources 丨〇丨a, 丨〇丄b and the masks 102a, 102b are configured such that the first illumination pattern and the first illumination pattern are at least partially superimposed. When illuminated by the first light source 1〇1&, portions 104a, 1〇5& of the first mask 102a form a specific pattern corresponding to the first illumination pattern. Similarly, when illuminated by the second light source 1 〇 lb, portions l 〇 4b, l 〇 5b of the second mask 〇 2b form a specific pattern corresponding to the second illumination pattern. Therefore, under illumination, the portions i 〇 4b, l 〇 5b of the second mask 10b are provided with the illumination pattern formed by the portions 104a, 105a of the first mask 1 〇 2a A complementary special lighting pattern. In particular, the portions of the second mask 10 that allow light to be transmitted may be configured to correspond to the portions of the first mask 1〇2& blocking light transmission, and the The portions of the two masks b02b that block light transmission may be configured to correspond to the portions of the first mask 102& allowing light transmission. Preferably, the first illumination pattern and the second illumination pattern are projected such that they are at least nearly all superimposed (i.e., overlap each other). The light intensity of at least 159509.doc -14-201224329 of the first light generating unit 110a and the second light generating unit u〇b can be adjusted with respect to the light intensity of the other light generating unit. In this particular embodiment, the light intensity of at least one of the light sources 101a, 101b can be adjustable. In order to provide a pattern mode for the illumination device, the two light sources 101a, 101b can operate at different light intensity levels, thereby providing a pattern by superimposing the first illumination pattern and the second illumination pattern. Projection 120a' is depicted in Figure ia. To provide a functional mode to the illumination device 1, the two light sources 1〇1, 1〇1b can operate at the same light intensity level. As a result, a more uniform light distribution will be provided by the stacking of the first illumination pattern and the second illumination pattern, as represented by the homogeneous illumination region 120b in Figure lb. Another embodiment of the present invention will be described hereinafter with reference to FIG. 2. 2 shows a lighting device 2 including a mask 200, a first light source 201a and a second light source 2〇1b. The mask 2 分离 separates a first region 21〇a of the first light source 2〇1a from a second region 210b where the second light source 2〇1b is disposed. Although the current embodiment is not limited to this configuration, the first light source 201 a and the second light source 2 〇 1 b may advantageously be symmetrically disposed on different sides of the mask 200, that is, from the mask 2〇 〇 at the same distance and facing the opposite side of the mask. In particular, a deviation from the symmetry of the light sources (2〇la, 2〇lb) may preferably be less than the size of the light sources. When in the functional mode, the illumination device can provide a total (at least a majority) offset of the patterned projection in this case. The mask 2 can have a portion 204 that allows light to be transmitted, and a portion 2〇5 that blocks light transmission. According to the current embodiment, at least a first side 22A of the mask 200 can be (at least partially) reflective. It should be understood that if the light sources are not provided in a symmetrical manner with respect to the mask, 159509.doc -15-201224329, then the first known pattern and the second illumination pattern may not fully complement each other, and, This configuration is still advantageous in that the illumination device provides a number of light pattern effects. For this purpose, the relative intensity of the first light source and the first light source can be varied (controlled). For a total compensation of the illumination patterns, the light sources are advantageously arranged in a symmetrical manner with respect to the visor. The uniform illumination is obtained by superimposing the first illumination pattern and the second illumination pattern. Further, it should be understood that the first light source and the second light source are emitted at the same level. Light and a complement to the first illumination pattern and the second illumination pattern, the sides of the mask are advantageously equipped with a highly reflective material. Furthermore, the mask 200 may, for example, have a portion of a dichroic filter. Transmitting a knives of a color spectrum of light emitted from the first source (2〇1a) and reflecting a complementary portion of a color spectrum of light emitted from the second source (2〇1b). When a light source 201a illuminates the first side 22〇& of the mask 2, the light beam 202 from the first light source 201a will be reflected by the reflective and blocking light transmitting portion 205, thereby providing a a first illumination pattern. In addition, when the second light When 20 lb illuminates the second side 220b of the mask 200, the light beam from the second source 20 lb will pass through the mask 2 to allow the light to pass through the portions 204, thereby providing a second illumination a pattern, which is correspondingly complementary to the first illumination pattern, and superimposed on the first illumination pattern. The light beam 203 emitted by the portion 2〇4 from the first light source 201a through the allowable light transmission is then provided a third illumination pattern. Advantageously, the second side 220b of the mask 200 can also be reflective, 159509.doc • 16-201224329 whereby the second source 201b can be derived from the mask 2 The light beam reflected by the reflective and blocking light transmissive portion 205 provides a fourth illumination pattern. Accordingly, the fourth illumination pattern is complementary to the third illumination pattern and superimposed on the third illumination pattern The light intensity of at least one of the first light source 201a and the second light source 20lb is adjustable, thereby providing a switchable patterning function. Therefore, the lighting device 2 can provide a pattern according to the current embodiment. Mode and a functional mode. 'The light sources 20 la, 20 lb may be dimmable. Still with the embodiment described with reference to Figure 2, another embodiment of the present invention will now be described with reference to Figures 3, 4 and 5. Figure 3 A lighting device is provided that includes a first mask 31, a second mask 320, and a third mask 330, which are configured such that the three masks are placed at an angle of about 120 from each other. As a result, a first region 3〇6 defined by the first mask 3 10 and the second mask 320 is formed. Similarly, a first one defined by the first mask 310 and the third mask 330 is formed. The second region 307 forms a third region 308 defined by the second mask 320 and the third mask 33A. As used herein, the term "about 120." means that the three masks are not necessarily exactly 120 apart from each other. Placed at an angle, but at a distance of about 120 from each other. ±20. Placed at an angle. Additionally, at least one of the three masks 310, 320, 330 can be reflective. Depending on the need, the sides of all three masks can be reflective. The illumination device further includes a first light source 3〇1a disposed in the first region 306, a second light source 3〇1b disposed in the second region 307, and disposed in the second region 308. A third light source 301c. Preferably, the three light sources 159509.doc • 17-201224329 3〇la, 30 lb, 301c may be symmetrically arranged between the three masks 310, 320, 330, ie, each distance A mask is the same distance and may be the same distance from the two masks. In the case of the embodiments, the masks may be equivalent to those described with reference to Figures ja, i and 2, and are provided with portions that allow light to be transmitted and portions that block or reflect light. In still another embodiment of the invention, the illumination device can further include four masks 410, 420, 430, 440, as depicted in FIG. The four masks are configured such that they are about 90 apart from each other. Place it at an angle to provide four areas. In the current embodiment, the term "about 90." means about 90 ° ± 10 °. Additionally, at least one side of at least one of the four masks 41, 420, 430, 440 can be reflective. Advantageously, all sides of the masks are reflective. Depending on the need, either side of any of the four masks can be reflective. The illumination device may further comprise four light sources 4A, 401b, 401c, 401d' each configured in each of the four regions in a manner similar to that described with reference to Figure 3.

Device. Figure 5 shows an example of a patterned projection provided by the illumination device (i.e., having four masks and four light sources) as described with reference to Figure 4. The examples are presented in a table in four rows 5 05 to 5 08 and four columns 501 to 504. Patterned projections in four directions perpendicular to each other are shown in lines 505, 159509.doc -18·201224329 506, 5 07, 508. A first column 501 shows a patterned projection when a light source is turned on and the other three light sources are turned off; a second column 502 shows a patterned projection when the two light sources have substantially the same light intensity and the other two light sources are turned off; A third column 503 shows a patterned projection when three light sources have substantially the same light intensity and _ light sources are off; and a fourth column 504 shows a patterned projection when all of the light sources have substantially the same light intensity. Figure 5 illustrates the possibility of providing a plurality of patterned projections with a lighting device in accordance with one embodiment of the present invention. Although the embodiments described with reference to Figures 3 and 4 respectively comprise three or four sets of light sources and masks, it is contemplated that the illumination device can include six, eight or any other suitable number of masks and a corresponding number of light sources. Another embodiment of the present invention will be described hereinafter with reference to FIG. 6. Figure 6 shows an illumination device comprising a first light source 601a and a second light source 601b placed on the same side of a mask 6''. The mask 6 is equipped with a portion 6〇4 that allows light to be transmitted. The configuration of these portions 604 forms a periodic pattern. The mask 600 can be further equipped with a portion 605 for blocking light transmission. The two light sources 601a, 6〇1b are placed at a distance from one another for about one-half of the period in the periodic pattern. As used herein, the term "about half" means that the light sources 601a, 601b are not necessarily placed at exactly one half of the period of the periodic pattern. It should be understood that some shifts may not affect the function of the lighting device. The light sources 6〇la, 6〇 may also be placed at substantially the same distance from the s-hai mask 600, as desired. It will be appreciated that for a full cancellation of the complementary illumination patterns, the sources are 159509.doc 19-201224329 advantageously disposed at exactly half the pitch of each other from each other. The shift is preferably smaller than the source size (which is preferably point shaped). An example of different periodic patterns that may be utilized in a lighting device according to one of the current embodiments is illustrated in FIG. For example, the periodic pattern may include a configuration of the transmission and non-transmissive strips of the parent with good visibility, a configuration of 8's, a parental transmission and a non-transmissive grid (or a checkerboard). 2. In addition, the periodic pattern can be designed more freely, such as a configuration 803 of an elliptical shape on the strip, a configuration of a cross-shaped strip on the strip, a configuration of a hexagonal shape, a configuration of 8六5 or a wave-shaped configuration. 8〇6 or any other configuration that provides a periodic pattern. A current embodiment of the invention can be used in the omnidirectional light bulb 700 shown in FIG. The mask can then be placed within the bulb. It will be appreciated that any of the illumination devices described herein (particularly with reference to FIGS. 1a, 1b, 2 to 4, and 9) can include a housing in which the mask is encapsulated/ A mask, and the light sources, thereby forming a light bulb. In the following, other embodiments of the invention will be described, which may be combined with any of the previously described embodiments. The figures, which may be referred to hereinafter, are merely illustrative of non-limiting examples of how such embodiments may be implemented. As shown in Figures la and lb, the lighting device can include a control unit 1 〇 3 configured to control at least the first light generating unit 丨丨〇a and the second light generating unit 〇 〇b The light intensity of one. The control unit 101 can be configured, for example, to receive a remote signal to adjust the light intensity and/or control the light generating units 110a, 110b. In particular, the control unit 1〇3 159509.doc -20· 201224329 can be configured to sequentially switch the light generating units to on and off to provide a visual effect such as a moving pattern. Additionally, the illumination device can include at least one additional light generating unit to provide at least one additional illumination pattern corresponding to, for example, the first illumination pattern (or the second illumination pattern) and slightly displaced therefrom. The control unit 103 can then be configured to sequentially switch the first light generating unit 110a (or the second light generating unit 11〇1?) and the additional light generating unit to on and off, whereby A moving pattern can be provided. Figure 9 shows an example of a lighting device having a control unit 9〇3. The illumination device includes a mask 900 that is reflective on one or both sides 92〇a, 92〇b and is provided with a portion 9〇4 that allows light transmission and a portion 905 that blocks light transmission. A first group of 9 〇la light sources is disposed at one side 92〇a of the mask 900. The first group 901a includes at least two light sources 9〇ia. At the other side 920b of the mask 900, a second group of 9 lb light sources is disposed. The second group 901b includes at least one light source 901b, and two or more additional light sources 9〇lbi as needed. The control unit 903 can, for example, be configured to sequentially switch one of the light sources 901a', 901b' to on at that time, thereby providing a moving pattern. The light sources 901a, 901b can be placed in any desired manner, such as symmetrically on each side of the mask, as shown in FIG. It will be appreciated that a light source indicated as 901 a' and its corresponding light source indicated as 9 〇 1 b' are advantageously arranged in a symmetrical manner with respect to the mask 9 ,, as illustrated in FIG. Embodiments including a control unit and an additional light generating unit (or additional light source) to provide a moving pattern can be described with reference to Figures 1a, 159509.doc - 21 - 201224329 lb, to Figures 4 and 6 through 7 Any combination of, for example, when two or more masks are provided, or when all of the light sources are on the same side of a mask. According to other embodiments of the present invention, the illumination device may have an additional light source, not only for the purpose of providing a moving pattern, but also for providing a solid, extra shiftable from the first illumination pattern and/or the second illumination pattern. pattern. The illumination device can then have a further additional light source as needed to provide complementary to the additional illumination pattern and at least partially superimposed on (iv) external illumination - the illumination source L can have the first light source and the first The two light sources are different in color to provide a color illumination pattern. At least one of the light generating units or the light sources may be dimmable, wherein the patterning is controlled to, for example, the possibility of brightness and contrast. For example, the light intensity of one of the light generating units 110a, n〇b may be higher, and the light intensity of the other light generating units UGa, (10) may be reduced to a slightly lower material, so that - patterned projection, but the total illumination from the Zhaoming device is still sufficient for normal illumination. The pattern pattern and the functional mode can be combined by & the light sources can be of any suitable type such as a conventional incandescent lamp or Advantageously, the light sources can be LEDs or any other type of point light source. If desired, the light source can reduce the brightness of the light source or more can have a scattering exit diffusion And smearing the projection error due to the finite mask thickness and the alignment error mask and placing the two light sources on the mask, especially when using the same side with a periodic pattern, or when making 159509.doc - 22- 201224329 It may be advantageous to use a number of masks placed at a specific angle from each other and such light sources are placed between the masks. In addition, a light source such as 5 hai may be a side-emitting LED to The light emitted by the LEDs is expected to be associated with its respective pattern projection optics. The light sources may (as an alternative or as a complement) have a shield 206, as shown in Figure 2. In addition, ' § hai et al The shield 2〇6 can be reflective such that most of the light emitted from a source is directed toward its associated pattern projection optics. The mask used in the embodiments of the invention described above can be several ° For example, the mask/the masks may have a 'sharp portion' that blocks the transmission of light, a translucent portion that only allows transmission of a certain oil
