Description of the Invention: [Technical Field of the Invention] The present invention is an indoor lighting fixture, particularly a light-emitting diode flat panel lamp. [Prior Art] The light guide plate can convert point and line light sources into surface light sources. Due to its ultra-thin, light, uniform light, high efficiency, energy saving and stable financial use, it has been increasingly used in the field of display screens, devices and lighting fixtures. The light guide plate lamp component usually adopts a light-emitting body as a light source, and the light guided by the light guide plate is transmitted into the light guide plate, and finally transmitted through the high-conductivity light guide point to pass the light from the light-emitting surface of the light guide plate; Due to the characteristics of the light guide plate and the clock structure of the lamp components, the lamp components are generally thin, and the resulting light is relatively uniform and has less dark areas, and generally meets the daily requirements of most products. However, for the field of high-end lighting, especially for displays requiring high precision, ultra-thin, energy-efficient use, high light uniformity, no dark areas, the current LED tri-panel lamps still have quite a few disadvantages, mainly It embodies the strict requirements for 14-lying, nuclear-converted light-emitting diodes. The choice of Rilin but f(4) is more resistant to deformation. Consider the color of the light guide itself, most of it, no; To ensure high precision, raw materials will be very bad σσ^, and the process requirements are also very strict, showing that the choice of 201239266 will bring a surge in costs. The field of questioning is very concerned about the color temperature and energy utilization of light guide lamps. It can be said that any slight energy loss is unfavorable. However, the control of color temperature in the structure of light guide plate lamps in real IV usually needs to pass through two This color of the extreme month a comes through. In this way, when selecting the light-emitting diode raw material, the color temperature is extremely demanding, the cost and the process are not only high, but also due to the diffraction performance, the color saturation of α = ~ into ασ Not ideal; in addition, in terms of energy efficiency, the light emitted by the t-polar body enters the light guide plate from the air, and there is such a reflection loss. If this loss is reduced, the energy utilization rate will be more effectively improved. · 'The setting of the color temperature of the 4 lamps is directly realized by the light-emitting diode and the fluorescent powder (encapsulation, which is mixed by the fluorescent powder excited by the light-emitting diode light). In the working process of the light-emitting diode, Especially after long-term use, the rise of the fluorescent brilliance will produce color temperature shift and brightness attenuation, resulting in unstable color temperature, which is extremely unfavorable for the final light effect. 2 Light one body is a point light source, in the light guide lamp The components are usually evenly arranged: on the side of the light panel, there is still a dark band between each other, and if the distance between the small light-emitting diodes is eliminated to eliminate the light, the same length needs to use a light body, so It is bound to increase the cost, and it will burden the battery for all kinds of portable devices. If the color of the U33 is easily absorbed on the front side of the light guide plate, this part will be darkly affected, and the age will cause the loss of light energy, ' This is not worth the loss for the products with high light requirements. The light guide plate is effective for utilizing the energy of the LED, and the overall thickness needs to be 201239266 than the lateral emission of the LED body. The effect of using the light-emitting diode to prevent the lateral light energy loss of the light-emitting diode, and thus the Z-continuation of the thickness (4), so how to make the light guide plate a side of the first diode The effective use of light energy, 疋-a technical focus. τ, the light energy 4 in the light guide plate is gradually decreasing, so it will cause a non-uniform light, close to the light source part is brighter, away from the light source part is darker 'How to solve these problems is also a key technology. SUMMARY OF THE INVENTION The object of the present invention is to provide a light-emitting diode flat panel lamp to solve the high cost, energy loss, color temperature instability, color of the product. The problem that the saturation is insufficient, the thickness cannot be further reduced, and the light is not uniform. The technical solution adopted by the present invention to solve the technical problem thereof is: A light-emitting diode flat panel lamp, comprising: a frame; at least one light source of any color Fixing by the frame; a light guide plate fixed by the frame; fluorescent powder attached to a position corresponding to the light source at the side of the light guide plate, the fluorescent powder can Receiving light from the light source and transitioning to an excited state, so that the light guide plate receives the mixed light only from the light source and the glory powder; and a light reflecting plate disposed on the back side of the light guide plate, and reflects the light 201239266 line toward the light guide plate. As an improvement scheme, the light source is a blue light emitting diode (Biue-LED) or a violet light emitting diode (UV-LED), the fluorescent powder is a yellow fluorescent powder, and the lighting component can generate white light. 'The light source is a blue light emitting diode or a violet light emitting diode, the fluorescent powder is red, green and blue three-color fluorescent powder, and the lamp component can generate white light. The back surface of the light guiding plate is provided by etching, micro groove cutting, electroforming, The dot formed by the sand blasting or silk screen printing process. As a further improvement of the above scheme, the size or density of the dot is proportional to the distance of the dot from the light source. The light guide plate can be divided into multiple blocks to process optical problems, and the distance is The block near the light source has a smaller size or density, and the block located farther from the light source has a larger size or density. The size of the dots is increased according to the light _ turn, called; Xiao Tong is uneven in light and dark caused by conduction in the light guide plate. As another improvement of the above scheme, the distance between the net and the dot is inversely proportional to the distance from the light source, and the uniform light can also be achieved. As a further improvement, the size or density of the dots is proportional to the vector size of the dots from the light source, and the uniform light can be achieved. The structure can be arranged in a strip shape like a cylindrical shape, or in a circular, rectangular or triangular array, which can be set according to the need to achieve the light effect of 201239266. Further, the front side of the light guide plate is provided with a dot to increase the utilization of light energy. Further, the side position of the light guide plate to which the phosphor powder is attached is provided with a dot, which also increases the utilization of light energy. The most advanced improvement of the above-described scheme is that the guide field is provided with an optical film that receives the mixed light from the light guide plate and scatters it. The optical film can use the more common film 〇pticai diffuser sheet to achieve uniform light output; it can also use optical compound material (Diffuser+BEF) to achieve optimal brightness enhancement and homogenization. . Second, compared with the prior art, the present invention has the following advantages: Since the light source of the light source enters the portion of the light guide plate, the side light of the light source can be used to excite the phosphor powder, thereby effectively using the lateral direction. Light, and it is not necessary to consider whether the lateral light enters the light guide plate, so that the light guide plate can be made as thin as possible, even like the diameter of the light-emitting diode, and the invention can obviously reduce the thickness of the light guide plate and save the material cost. And the structure is made lighter; the invention can effectively utilize the lateral light and the forward light of the light source to excite the fluorescent powder, increase the energy of the light guide plate, and prevent the illumination angle of the lateral light from being excessively large and the light mutually canceling each other. Light loss; Since the final color temperature is determined by the light source and the phosphor light excited by the phosphor powder on the side of the light guide plate, the focus of the color temperature adjustment is shifted to the choice of the color and phosphor powder of the light-emitting diode 7 201239266. Generally, you only need to change the color of the phosphor powder, without having to set the light source or select the bin, which greatly simplifies the manufacturing. Art, and can eliminate the need to store light powder in the light source, reduce the packaging cost, even the choice of light guide (4), can also greatly relax the requirements, making the raw materials and process cost less; the light source does not have to be packaged together with the phosphor powder, so During the work process, the effect of heat on the phosphor powder will be minimized, and color temperature shift and brightness decay will not occur. If the phosphor powder is directly packaged in the light source, it is easy to realize four colors or more. Mixed light, good light diffraction, and better color saturation; directly apply fluorescent powder to the light of the light guide plate, the angle of light from the light source entering the light guide plate will be enlarged due to the refraction of the fluorescent powder. Reflex or secondary refraction, and with the excitation light of the phosphor powder, the mixed light finally entering the light guide plate is more uniform, and no dark band appears on the side of the light guide plate, and no need to be reused; In order to cover the side of the light guide plate, the energy loss is reduced, and the luminous effect is excellent; the color combination of the light source, the phosphor powder and the light guide plate, such as the blue light source, is used for color matching. Fluorescent powder and reddish light guide plate will easily achieve higher color rendering; using dots and their different shapes, combinations and arrangements will easily solve the problem of uneven illumination of the light guide plate; Compared with the prior art, the technical solution of the invention has the advantages of the cost and the technical difficulty of 201239266, and has a very large superior or lower material in terms of the effect of using the inter-span. Its technical performance will greatly exceed the existing similar production σ >r訾# It can be expected that its application prospect will be very huge. [Common application method] Shikou 1 |q*| As shown in the present invention, the light-emitting diode light guide plate lamp component is mainly composed of a structure, a light source 2, a light guide plate 3, and a fluorescent light. Powder 4 group 1 as a whole positioning structure, the light source 2 can adopt a light-emitting diode, l an ice plate or a side fixed in the frame 1 , and the green guide 3 is fixed by the frame 1 , and the guide The light board 3 can be a flat plate or a wedge type plate, and can be adjusted according to actual use, for example, for decoration and lighting fixtures, a flat panel structure can be used, and a backlight module of a notebook computer or a mobile phone can be used. Wedge plate structure; in the human light part of the side or side of the guide 3, the camping light 4 is attached to ensure the light emitted by the light source 2 toward the light guide plate 3, firstly irradiated to the phosphor powder 4 'so in the phosphor powder 4 After receiving the light from the light source 2, the light is excited to the excited state, and the excitation light is emitted, and mixed with the light of the light source 2 to form a mixed light, and the light guide plate 3 and the light source 2 are separated by the fluorescent powder 4'. The light guide plate 3 finally receives only the mixed light; in the present invention, Reflecting plate disposed on the rear side 6 of the light guide plate 3, the frame 1 can be secured or attached to the back side of the light guide plate 3, it can be used for the reflective element inside the lamp light, to improve efficiency. In the optical design of the light-emitting device of the present invention, the following options can be adopted: (D is disposed on the front surface of the light guide plate 3, and the mixed light received by the light guide plate 3 is diffused through the optical film 5) The optical film 5 can be used. Diffuser optics 201239266 film material, can make the light uniformity; (2) can also use Diff this and β Ε {? optical composite optical film, _ brightening and light uniformity of the best effect; (3) of course not required Any optical raft material can save cost, and the light uniformity can also be achieved by the structure of the invention. The real towel of the invention can reduce the distance of the money 2 from the _ light powder 4 as much as possible to reduce the loss of light energy, The best light effect, and the light source 2 is used to excite the phosphor powder 4 disposed on the side of the light guide plate 3, the lateral light of the light source 2 can be effectively utilized to illuminate the phosphor powder 4, regardless of whether the lateral light enters the guide. Light can only be used to achieve the effective use of lateral light and line energy to increase the energy of the light guide plate. Therefore, the light guide plate 3 can be made as thin as possible, even with the diameter of the light-emitting diode.本发_技术It is beneficial to solve the problem of the thickness of the light guide plate, and is suitable for the application in the field of size and lightness. In addition, as shown in Fig. 2, for the incident angle: the lateral light of the total reflection angle of the light plate 3 After being reflected back to the phosphor powder 4, secondary reflection or more reflection can be performed in the phosphor powder 4, which can be used to excite the camping powder core and can be incident on the light guide plate 3, thereby reducing the light loss. And preventing the dark band generated by the distance between the adjacent two light-emitting diodes, so that the light is more uniform and the energy loss is reduced. The light source 2 of the present invention can be used on the light-emitting diodes of various colors. Because the belly does not have to be packaged with phosphor powder, the heat generated when the light source 2 is operated, ~ is emitted to the fluorescent light 4, so the fluorescent powder 4 does not cause color temperature deviation and temperature decay due to heat generation. The color temperature control of the illuminating light~ from the original 201239266 is controlled by the color temperature of the light-emitting diode in the light source 2, and changed to the light source 2 and the camping powder i, and the same regulation, which is equivalent to the technical focus of setting the color temperature. , from the light source 2 '/ 冋 fine process , transferred to the simple process of the light source 2 with the camping powder 4, it can be seen that 'using the technology of the present invention, to achieve the required color temperature, basically only need to control the technical parameters of the light powder 4, from the technical cost point of view 'It is still very advantageous from the perspective of process difficulty. And - in the technical solution of this & Ming, the choice of raw materials for the light guide plate 3, ^ step by step reduces the standard 'because in the defect-deficient technology, the final light The color temperature and energy 'are large' will depend in part on the quality of the guide field itself. Generally, the yellow light quality of the light guide plate cannot be selected, otherwise the final light effect will be affected. The cost will be high; and this day (4) technology The color temperature of the light guide plate 3 can be taken into consideration in the light mixing effect, so that a relatively inexpensive light guide plate can be used, which can be advantageous in cost saving. The good performance of um can be manifested by several embodiments. For example, in an implementation of the present invention, the light source 2 is a blue light emitting diode or a violet (UV) light emitting diode. ^ Rewarding the private 4! The color can synthesize white light, and the other is the color rendering performance. It can also be a red color of the gentleman I曰r ', and σ 5 less I. Therefore, the light guide plate 3 can be reddish, so that the base color reaches the color rendering index. High color rendering performance above 90.

For example, only lower power consumption is required. "In addition to the above-mentioned implementation, it is possible to extend more implementations. For example, without considering the packaging cost of the light source 2 itself, a light-emitting diode of a phosphor powder material may be used, in combination with the glory powder 4, To achieve four-color mixed light or more n colors m, color development (four) will be very prominent. As a preferred embodiment of the present invention, a dot 31 is provided on the back surface of the light guide plate 3. The dot 31 can be prepared by etching, microgroove cutting, electroforming, sand blasting or silk screen printing to produce a dot 31 of the currently best screen printing process. The light transmitted by the light guide plate, the energy will be lost as the transmission distance increases, which is unavoidable, which is extremely unfavorable for the uniformity of the light guide plate 3, and the light guide plate due to various parameters of the mesh point 31 of the light guide plate 3. The energy of the transmitted light will have a certain relationship. In response to this problem, the present invention has several improvements: as shown in Figures 3 and 4, in an ideal state, ~, ', the size of the point or The density will be linearly proportional to the ray energy, and as shown in Figure 5, the distance between the dots is inversely proportional to the ray energy. According to the principle, the present invention can achieve the uniform arrangement of light by the following scheme: The first scheme: the size of the access point 31 of the light guide plate 3 is proportional to the distance of the light source 2 of the grid point, as shown in FIG. 'For the convenience of manufacturing, you can set up the block 30, the size of the dot 31 on each block 30, the density or the distance is not the same. 12 201239266 The same 'multiple blocks 30 can be stitched together to form the light guide plate 3, @为在When a light guide plate is made, especially for a large-sized light guide plate, if the dot production on a certain block 3〇 fails, it is only necessary to re-create the block 30, which is advantageous for cost saving; The smaller the size or density of the dots 31, or the larger the distance, the closer to the light source 2, the smaller the size or density of the dots 31, or the block 3 with the largest distance, which is located at the entire light guide plate 31. At the edge, closest to the light source 2, the side is the area to which the phosphor powder 4 is attached; the larger the size or density of the dot μ, or the smaller the distance, the farther away from the light source 2; The design can basically be the light from the light guide plate 3, so that 3 looks uniform brightness throughout the light guide plate. Of course, as shown in FIG. 7, the whole light guide plate 3 can be used, which is suitable for a light guide plate with a small area, and the dots of different sizes, densities or distances are arranged on the light guide plate 3 substantially in a decreasing or incremental manner. For a uniform light effect. The first scheme: designing the distribution of the dots according to the vector such that the size or the twist of the dots & is proportional to the vector size of the dots 31 from the light source 2, or the dot distance is inversely proportional to the vector size of the dots 31 from the light source 2. The implementation manner of the solution can be as shown in FIG. 8. For example, the light source 2 can be located at a corner side of the light guide plate 3, and then the light source 2 is centered on the light guide plate 3 at a different distance from the light source. In some areas, according to the distance of the area from the light source 2, the dot 31 may be arranged according to the above rule; further, considering that the forward light energy of the light source 2 is greater than the lateral light, the same distance from the light source 3 from the light source 2 At the same time, the brightness at the forward ray will be greater than the brightness of the lateral ray, as 13 201239266. As shown in Fig. 9, according to the angle area of the light guide plate 3 and the light source 2, the center line portion where the forward ray is concentrated Divided into one region, symmetrically partitioned into two weeks, wherein the mesh point 31 of the middle line portion has the smallest size or density, or the largest distance, and sequentially increases or decreases toward the two sides. According to the above solution, the invention can conveniently solve the problem of uneven light of the light guide plate, and the effect is very satisfactory. For the light guide plate luminaire component applied in the field of horse end, the energy utilization rate of the light source 2 is the key to assessing the quality of the technology. Therefore, based on the above solution, the present invention also provides several preferred embodiments, which are advantageous for Try to increase energy efficiency. For example, the shape design of the dots 31 may be arranged in a zigzag (V-CUT) as shown in FIG. 1 or in a cylindrical shape as shown in the π-th diagram, or It is arranged in a trapezoidal strip shape as shown in Fig. 12, and a circular-like microlens array as shown in Fig. 13 or a rectangular-like microlens array as shown in Fig. 14 may be used, or It is a triangle-like or diamond-shaped microlens array as shown in Fig. 15. All of the above solutions are beneficial to the effective use of energy. Of course, the shape of the dot 31 is not limited to the above several types. In a preferred embodiment of the present invention, a dot 31 may be provided on the back surface of the light guide plate 3. 'The structure is as shown in FIG. 16' and the dot 31 on the back side thereof can reflect and refract light, thereby achieving a secondary or Multiple refraction, the light is emitted from the front side of the light guide plate 3, and the optical film 5' is beneficial to the uniform diffusion of light, and the energy utilization rate can be increased by 7 to 8% under the same conditions. In addition, as shown in FIG. 17, in a preferred embodiment, the side position of the light guide plate 3 to which the phosphor powder 4 is attached may be provided with a dot 31 which can be reflected back when entering the light guide plate 3. The light generates secondary refraction or multiple refraction, and avoids the light that is incident on the light guide plate 3, and the light that is opposite in direction along the original path is partially reflected back to cancel the light loss, so under the same conditions, Can increase energy utilization.
