Description of the Invention: [Technical Field] The present invention relates to a color-developing color-developing planar light-emitting source that is mainly used for the surface of a light source capable of exciting a luminescent phosphor photoluminescence. Forming a light-transmissive area and a coating area, coating a fluorescent powder block which can be excited by different luminescent colors on the coating area, and penetrating the fluorescent powder coating area by using a light source capable of exciting the fluorescent powder photoluminescence The different wavelengths of light produced afterwards, while the mixed light source source produces white light with high color rendering function. • [Prior Art] Press, for lighting and light, the first consideration is the key issues of illuminance, color rendering, color temperature, etc. In terms of white light, the color temperature is blue and reddish to white light. The effect is generally based on the human eye's perception of "white light". It should be derived from the feeling of sunlight. As long as the light contains light of different frequencies similar to that of sunlight, it will produce a "white light" feeling, while its color rendering is It is the percentage of the real feeling of the object under the light source and the feeling of the feeling under the sunlight. However, the light source with high color rendering is more realistic for the color φ, and the object presented by the eye is closer to the natural original taste, and the continuation [color temperature] is used to describe The color mixing effect of a particular light source, that is, the color temperature represents the scale, unit of the light source color. K (Kelvin). Different light colors have different color temperatures, the lower the color temperature (2800°K), the light color is reddish, giving a warm feeling; the color temperature is slightly higher (5〇〇〇°Κ), giving a comfortable feeling. The color temperature is high (65001), and the light color is blue, giving a refreshing feeling; therefore, the change in the color temperature of the light source will affect the indoor atmosphere. The so-called white light is a mixture of multiple colors of light. At least two kinds of light must be mixed in the form of white light visible by human eyes, such as two-wavelength light (blue light + yellow 5 200804728, and long light (supervised light + green light +) Red light), and the known white light first / original I method has the following types: Light-emitting diodes, respectively, control the current through the diode, and emit red, green, blue light, three colors mixed to produce white light. 2.==The county's diodes are difficult to pass through the current of the second shop, while the yellow-green light or the blue-green and red light's two colors mix to produce white light. Gallium-emitting two-pole slit light' with the yellow light of the brain stone right type The light powder 'mixes two colors to produce white light. 4.=Forms a film on the crystal substrate. 'The film emits blue light after being energized, and the same part is emitted on the substrate to emit yellow light, and the white and yellow light complement each other to produce white light. Each external light white light · polar body (2, excited) w red, green, blue species: fire first powder (8) [for light. [as shown in the eighth figure ί] issued light, through the full color to produce white 6 · Produce white light by using the UV tube to excite the fluorescent powder of the tube (4). 7. Inorganic material Or electroluminescent elements made of organic materials produce white light. 8. ΐί=ΓΓΓ 式 电子 电子 发射 发射 发射 激发 激发 激发 激发 激发 激发 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 The powder produces white light. However, all of the above methods have a defect, that is, the second method must be controlled by current in addition to the circuit _, the cost is higher, and the second type of white light with two colors is not easy to mix the normal color temperature. In the third to fifth modes, it is only impossible to adjust the color temperature, nor can it produce white light with high color rendering. 4 6 ways can be used, and the seventh method is difficult to break through the life of the material. The method is complicated and difficult to implement, and the color rendering can only be 6 200804728 and the conventional cathode ray tube is reduced, the color rendering performance of the ninth method is difficult to improve, and the lifetime is worse than that of the solid-state semiconductor element. In view of this, the inventor In view of the fact that the above-mentioned white light illumination originates from the actual system = and the lack of implementation, it is corrected and improved, and at the same time, in the spirit and philosophy of seeking for good, and with the help of professional knowledge and experience' After many ingenuity and experimentation, the present invention has been developed to provide a device capable of coloring a high color rendering planar light source to improve the prior art while improving the color rendering of the light source.
