Description of the Invention: [Technical Field] The present invention relates to a positive light illumination device, and more particularly to a positive illumination for an advertising print or a liquid crystal display (4) for display in a small area of daily life. Device. [Prior Art] Hanging the moonlight illumination mode is based on the acrylic advertising light box, and most of the fluorescent tubes are placed in the light box. At the same time, the semi-transparent material such as the atomized acrylic sheet is used as the side plate of the light box to achieve the transparency. Out-even surface light source effect, as a backlight for transparent advertising patterns or text, such backlight boxes are light, gentle and compatible with the environment. However, the disadvantage is that the light passes through the atomized acrylic sheet and the advertising drawings. The proportion of advertising backlights is low, and the light-emitting efficiency of the lamp is only about 10%. It is a high-energy, mercury-containing advertising product. The appearance of the box-type lighting is lacking. 'The location and size are not easy to install and install. It is not convenient to maintain the internal wiring. The internal light source and reflector cover occupy a large volume, which is not easy to meet the light and thin targets. The indoor advertising setting will shield the original light distribution. . During the strong wind season, there are occasions when the outdoor board is falling and wounding. In the indoor advanced kanban, it requires beautiful appearance, avoids stray light, energy saving and non-toxicity, and achieves the effect of advertising attracting attention. The light guide type advertising lighting method is gradually taken seriously. The advertising applications of the existing light guide plates are as follows: - After the patterns and characters drawn on the computer are cut by colored transparent stickers, such as 3M's "Card Point West Germany" stickers, they are attached to the light guide plate to form a backlight or a positive light advertising lighting. The effect is a combination of traditional lamp 201140524 phase advertisement production technology and light guide plate. The advantage is that it is beautiful, does not occupy space and can have the characteristics of light-emitting diode (LED). The disadvantage is that there is only simple pattern advertisement. The effect is that the illumination of a large area is not uniform, and is generally applied to the indoor directivity indicator. Second, the entire light guide plate is engraved with a numerical control machine (eomputei·numerical contro) for v-grooves of text or image lines. The V-groove has a prominent effect on the scattering of positive light, but the proportion of stray light directly to the eye is high, and there is a limit to the expression of delicate patterns or colors, which is generally used for simple indication functions. 3. The use of transparent glue to tight the advertising drawings It is attached to the light guide plate to achieve the positive kanban effect of the whole printed advertisement, but for the advertising printing paper with a width of more than A4, the peripheral light appears. In the middle of the dark uneven distribution of light, so in Buco, a bubble will produce a sudden bright spot, its wide ~,, month effect is significantly attenuated 'again, the light guide plate is easy to leave residual glue, on the subsequent advertising drawings It is extremely inconvenient to replace; Fourthly, South Korea's Samsung Electronics (Wur (6) has introduced a large-size LED backlight LCD TV τν such as ultra-thin 3L f 50 leaves), and its ultra-thin backlight module is designed to inject the light guide plate from the end face side by LED light source. The light-scattering plate is provided with a plurality of scattering points on the side of the light guide plate, and is distributed in a strip shape, and at the same time, the surface light source of the other side-side scattering material is recognized by the material of the transmissive (four) panel. In the large nJT group is a silky, high-priced product, it is not easy to apply 2 publicized kanban market; want her to (4) face light, and the production process should be equivalent to the optical and the surface characteristics of the board, such as _, scattered _ Discussion, looking for the design of the light-guided bullying point, the distribution of the V-groove and other parameters, · 201140524 for the need to go back and forth between the design and production of the correction process, so that the production of large-size LCD backlight module often costs several Month's efforts. In general, the effective light utilization of the backlight type illumination device is low, about 10 20 /. Moreover, the uniformity of the large-sized surface light source is difficult to control, the manufacturing cost is high, and the size and shape cannot satisfy the use requirements of characteristics such as diversity and vibrancy of the advertising illumination. SUMMARY OF THE INVENTION An object of the present invention is to provide a positive light illumination device with high light utilization efficiency, low energy consumption, small footprint, and wide application range. The present invention provides a positive light illumination device, comprising: a light guide plate, a kanban plate and a plurality of transparent bumps, the light guide plate is disposed on the kanban plate, a plurality of transparent bumps are disposed on the light guide plate and the kanban H, and the number of the light guide plates is The transparent bumps and the kanban are combined with each other in an air gap manner. At least the end surface of the light guide plate is provided with at least an illuminating source, and the hair ray generates a light and is totally reflected in the light guide plate. The light is guided to the kanban through a plurality of transparent bumps, wherein the position of the plurality of transparent bumps is *reflected light in a discharge port in the light guide plate. The light source may be a light emitting diode, a laser diode or a cold cathode tube. The light emitting diode may be a white light emitting diode or a light emitting diode group composed of red, green and blue light emitting diodes, wherein the light emitting diode group respectively emits red light and green light. Light, blue light output a certain proportion of brightness or take a fast rotation time-sharing method to turn out, cast inside the light guide plate, this color light enters the eye in 201140524 through the visual effect to form a white light illumination source. The plurality of transparent bumps may be formed by dot printing, spraying, embossing, transfer, ultraviolet curing glue or mold forming. The distribution of the plurality of transparent bumps, the dot pitch, and the height are determined depending on the effect to be exhibited by the art, and there is no particular limitation. Generally, the distance between the dots of the transparent bumps may be between 0.1 mm and 10 mm, and the height of the transparent bumps may be between 5 〇 μηη and 1 mm. The kanban may be a dot print, a digital electronic print, an electronic paper kanban or an LCD kanban. The invention adopts a plurality of transparent bumps to connect the light guide plate and the kanban in a gapless manner, such as pressing on the light path to avoid reflection caused by the air gap and refracting the stray light, so that the visibility and contrast of the picture are better. Since the plurality of transparent bumps can be formed on the surface of the kanban or the light guide plate by screen printing, spraying, digital printing, etc., the position can accurately correspond to the inner valley of the kanban, such as text lines. Among them, a plurality of transparent bumps are printed on the printed matter, and the positional accuracy is most easily achieved, and the connection between the subsequent kanban and the light guide plate is not affected. Therefore, the description of the following embodiments is convenient, but is not limited thereto. Because a plurality of transparent bumps belong to the microscopic illumination, the viewer sees the picture composed of most small colored dots, and its size, height and dot distance directly affect the comfort of the picture. According to the viewer's position, 1 metre away, the point of the viewing kanban should be ', the spoon is within 10mm, and the point of the viewing plaque 1 metre away should be within about mm. With the current transparent glazing ink output technology, the dot spacing can be at least 201140524 100dpi (dotper inch 'per mile per dot) 〇.25mm, so in the following embodiments, the ink glazing technology can cover close distance, such as 25cm. The viewing point of the indoor billboard. In the future, the demand for electronic high-precision, higher-resolution kanban illuminating illumination will be generated by the process of manufacturing the electronic kanban itself, so that the point source generated by the bump is precisely aligned with the opening position of each element in the kanban. Moreover, as close as possible to the layer of the primitive, increasing the optical aperture value, that is, the ratio of the aperture area/distance, can effectively increase the utilization rate of the illumination source. At the time of use, at least one directional light source is forwardly injected into at least one end surface of the light guide plate, and the remaining end faces of the light guide plate are covered with a reflective material to form an environment of ideal reflection light guiding. Taking an acrylic light guiding material having a refractive index n=1.55 as an example (as shown in the “Fig. 2” of the subsequent embodiment), the projection angle is within ±5 光线 because the light satisfies the total reflection condition 'in the acrylic The material is continuously reflected without loss of interface and eventually fills the inside of the light guide. The air-free gap characteristic of the plurality of transparent bumps and the surface of the light guide plate produced by dot printing can no longer limit the total reflection condition, and will be partially leaked through a plurality of transparent bumps according to the position thereof, that is, Kanban (such as advertising drawings) produces local precision positive lighting. Because the shape of each transparent bump is similar to the boundary condition, the brightness of each penetration is high. The distance between the light source and the orientation is small, and only the total number of transparent bumps set in one area is A slow ratio, so the optical simulation vector is calculated to be about the total amount of scalar relationship in the area, greatly simplifying the problem of the spacing and distribution design of the conventional light guide plate' is a major feature of the invention. Advertising designers do not need to have optical knowledge, intuitively adjust the number of outlets, that is, the ratio of black and white in the dot to 201140524, you can arrange the light distribution of the layout, so that the design, size and shape of Zhengguang advertising kanban lighting are more flexible. Can be personalized, singular. Each of the transparent bumps is bright and bright, and is placed on the screen according to the advertisement designer's request according to Lang (4), so that the position of the illumination can be completely completed. Through a plurality of positive bumps and a light guide surface, the light reaches the surface of the advertisement sheet or is close to the liquid crystal layer of the reflective LCD panel because there is no air.

Recently, the e-books that are well watched on the market, the firefly _ uses a removable electronic paper material, the viewing distance is about 20cm~40cm, and the effect of the image and the LCD panel is the same as the black-self-contrast to express the lines and acid Commercial appeals seek to be the mainstream of power saving. Because the electronic paper is not actively illuminated, the imaging particles themselves are opaque. It is also impossible to use backlight illumination. The ambient light is used to display the content, which is not suitable for dim occasions. Therefore, this hair _ whistling - positive lighting device. In addition, the positive illumination is fine on the reflective panel, and Chanel's light remains clear. This can increase the real (four) combination of the e-book. According to the _ illuminating source, the good wavelength of the sun is better. The LED is a narrow-band monochromatic light source, so the color rendering of the coffee light is an important indicator of the sewing product. Wei Cai's 妓 grade segment LED is combined with its _ color _ material inspection, called, the yellow _ light mixed with white light effect 'but the red and green components are obviously low, playing _ standard muscle. The new-generation LED _ has already made the _ color _, that is, the ratio of red, green and blue coffee to a white light source, its color rendering can reach 90%, 201140524 but still limited by the built-in color of the LCD The color of the film is saturated. More advanced, such as the 3m company CM200 LED projector's color correction method, and abandoned the idea of color filters, with the high color purity of the red, green and blue LED light source to directly illuminate the 'box-frame content into red The sequence of the three groups of green and blue is quickly presented to the audience. The three sets of frames displayed quickly reduce the effect of white light illumination under the effect of persistence of vision. The color saturation expression of this method can surpass the National Television System Committee (national). The specification of television system committee 'NTSC), the color rendering can reach Π0%', the images appearing can be a bit confusing, and there is a good chance to become a mainstream product. The above-mentioned color LED lighting can obviously cooperate with the positive light illumination device of the present invention, and can be applied to full color display of electronic paper and LCD panel, which can greatly enhance the future growth of the product. To make full use of the light and thin features of electronic paper products, the positive light guide plate needs to be relatively light and thin. 'How to make the light source more efficiently enter the end face of the light guide plate, and the laser can be used as the side light. On the one hand, the laser can be easily focused. The end face is injected into the thinner (four) light plate and maintains the flexibility of the e-book product, while the misaligned parallel light allows the flexible light guide to withstand a larger 'f curvature without leaking light at the corner. If the kanban is replaced by a conventional kanban, the invention can also be used as an indoor general lighting fixture such as a table lamp or a wall lamp. This also falls within the scope of protection of the present invention.

[Embodiment] The present invention will be further described below in conjunction with the drawings and the embodiments. Embodiment 1 Please refer to FIG. 1 , FIG. 2 and FIG. 3 . The embodiment includes a linear light source 1 and a light guide plate 2 . The light guide plate 2 has no transparent air on the surface of the plurality of transparent bumps 5 . The connection of the gap is a billboard, for example, an advertisement drawing 6; the total reflection light in the light guide plate 2 is guided to the front surface of the advertisement drawing 6 via a plurality of transparent bumps 5, and the position of the plurality of transparent bumps 5 is the light in the light guide plate 2. The discharge outlet, the distribution coating 7 of the plurality of transparent bumps 5 conforms to the advertising content pattern, and produces a locally emphasized lighting effect. The distribution, the dot pitch, and the height of the plurality of transparent bumps 5 are determined according to the effect to be exhibited by the art, and there is no particular limitation. The light guide plate 2 has an end surface 31 provided with a linear light source 1, and the remaining end surfaces 32 are covered with a reflective sticker 4; the linear light source 1 is formed by an LED light source (but not limited thereto) 201140524. The linear light source 1 generates a light ray and couples the light into the light guide plate 2 (as shown in FIG. 1). The reflective sticker 4 reflects the light back into the light guide plate 2 to improve light utilization; the light passes through numerous times. After reflection, the light that meets the condition of total reflection angle (as shown in "Fig. 2") is filled in the light guide plate 2 and cannot be separated, forming the necessary condition for the uniform illumination of the present invention; the plurality of transparent bumps 5 have no air gap. Combined with the surface of the light guide plate 2, the condition of total reflection optics changes, and the damage light will penetrate the transparent bump 5 without air gap and the object of the outer surface of the light guide plate 2 (as shown in Fig. 2) , such as advertising drawings 6. A technique of screen printing can be used to provide a plurality of small transparent bumps 5 on the surface of the advertisement sheet 6 or the light guide plate 2. If the shape and size of each of the transparent bumps 5, that is, their optical boundary conditions are similar, the light of the single transparent bump 5 is extremely similar in the same region. The overall illumination quantity design of the advertisement drawing 6 will be converted into a functional relationship of the large area, and the illumination design (such as "the first uniformity, the gradient gray scale change or the color tone" can be obtained without the simulation of the county. 3 Figure "No" ° The size and density of a plurality of tiny transparent bumps 5 determine the illuminance required to design a wide-grain fruit, which is a feature of the present invention. The invention utilizes the precise pattern of 12 〇dpi bumps on the drawings by screen printing, that is, the position of the light spot is less than the size of the finished product of the industry, and the invention is cost, manufactured, maintained, The content is clearly superior to the arranging type of coffee product. In addition, 'advertising printing inks also provide a richer color of light through a plurality of transparent bumps 5 completely directed to the advertising drawings 6: front: 201140524 A large number of light points and rich color conveyed to the eyes of the eye, which The light that is not transmitted through the bump 5 will be continuously reflected in the light guide plate 2, so that the picture of the present invention is completely stray-free when viewed. The screen printing design of the same density produces different lighting effects such as hook and fire heart. - Low-cost advertising drawings G, after the active illumination of the light source and the non-active lighting (4), can express - dynamic appeal, '! If the company phone or slogan can be printed on a white background with a plurality of transparent bumps 5, the money does not know its existence under the external illumination; but when the night is dark, the light source is _ after the light, the bright bump 5 into a luminous bright spot, the white back hall, the lack of light due to the lack of light to the dark side, this - dual dynamic effect is the invention's other large features ' In addition, there are easy to mass production, construction, replacement of advertising printed objects, etc. . Embodiment 2 Please refer to "Fig. 4" 'This embodiment includes - light guide plate 2 and - kanban, for example, a reflective LCD panel 1 〇, transparent bump coating u is a fine print on the light guide plate 2 The male appearance of the transparent bumps, the gradual effect of the + central money gradually loosening around, can compensate the laterally injected linear light source, forming a uniform LED positive light plate 20' and then the forward airless gap combined with the reflective type The LCD panel 10 forms an LED illuminating lCD kanban 3 〇. Each of the end faces of the light guide plate 2 is provided with a linear light source 1; the linear light source 1 is formed by, but not limited to, an LED light source. The present invention utilizes a plurality of LED light sources (but is not limited thereto) to arrange the linear light source 1 , and injects the light emitted therefrom into the end surface of the light guide plate 2 (as shown in FIG. 4 13 201140524) 'light rays in the light guide plate 2 Light that is constantly reflected and conforms to the total reflection condition is filled in the light guide plate 2 and cannot penetrate to the outside. The distribution of the plurality of side-type transparent bumps can be planned via the characteristics of the optical simulation light source, that is, the linear light source, and the light distribution can be (4) uniform (10) finely distributed. For example, the distribution density of multiple micro-transparent bumps in the (four)-point coating] is reduced from the central region to the edge region or adjust the number of dots, that is, the duty ratio of black and white in the dot, which can be easily set from 1. /. The output of the dot to % is compensated to compensate for the phenomenon that the light of the linear light source ι is caused by the number of transparent bumps. The coffee light source _ village photography material LCD panel 1 〇, so that the light is all infused with the reflective LCD panel 1G and the domain leaks, so the light utilization efficiency is improved 'and the stray light is reduced; and because the plurality of transparent bumps are positive To the liquid crystal layer in the reflective LCD without air gap, the light is passed through the liquid crystal layer for the first time, and the second time, the driver wears the eye. The positive light-removing reflective LCD panel 1G will enter and exit all optical components twice, such as liquid crystal layer, color filter surface, polarization layer, etc., in the path of optical entrance and exit, double masking effect The image produced by the LCD of _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Please refer to "5th Edition" "The invention can be used to enhance the transmittance of the entire panel". The unit of the unit is only partially transparent. It is called the element (4) element) opening 51 'the rest The parts are passive signal line %, black frame, thin film transistor (thiiKfilm tmnSistGI· 'TFT)|_element η, where the unit area of the primitive opening 51 than the unit figure 5G is called the open sigma ratio, at high resolution (10) The opening ratio of 201140524 is only about 60%~70%. 'The micro lens manufacturing technology, such as UV curing glue, is combined with the baking process to make a plurality of micro transparent bumps on the surface of the LCD panel. The micro transparent bumps are disposed at the pixel opening 51 to be in an opposite relationship with each of the pixel centers of the LCD panel, and the percentage of light entering the primitive opening 51 via the plurality of transparent bumps in the light guide plate will be It can be greatly increased, which can improve the covering problem associated with the circuit and the compartment when the LCD picture element is produced, and can improve the luminous flux efficiency of the LCD. The microlens process has been widely used in the fabrication of complementary metal oxide semiconductor (CMOS) and charge coupled device (CCD) sensors to increase the sensitivity of the low light. However, in the illumination of positive-light LCD or electronic paper, in addition to increasing the brightness, the stray light can be reduced to increase the contrast, and the burden of vision during reading can be reduced, which is extremely valuable for development. Right on the polarized material to make the transparent bump and the interface with no air gap, the light that has not passed through the polarized material will be reflected back into the light guide plate and continue to be recycled. LCD panels are more simplistic and efficient than existing backlights in the use of positive illumination. While the embodiments of the present invention are disclosed as described above, it is not intended to limit the scope of the present invention, and the scope of the invention is not limited by the spirit and scope of the present invention. Structure, characteristics, and spirit can be changed ♦ 'Therefore, the GG's Guardian is determined by the scope of the patent application attached to this manual. 15 201140524 [Simplified description of the drawings] Fig. 1 is a schematic view showing the coupling of the light of the linear light source of Embodiment 1 of the present invention into the light guide plate.
