Description of the Invention: [Technical Field] The present invention relates to a filter coating for a light-emitting element, and the filter material can filter a light source generated by the light-emitting element, so that the filter light source has a relatively uniform spectrum distribution And color rendering. [Prior Art] Light-Emitting Diode (LED) is widely used because of its long life, small size, low power consumption, fast response, no radiation and monochromatic luminescence. It is used in various products such as indicator lights, advertising billboards, traffic lights, car lights, display panels, communication devices, and consumer electronics. Among them, the illuminating element that can produce a white light source can be used to replace the traditional incandescent lamp and become a new generation of illuminating light source, which is more popular in the world. According to the current white light-emitting components, there are three main methods: ❹ Three light-emitting diodes that can generate three different wavelength bands (such as red, green, and blue) are placed in the same package, and by various colors. a mixture of light (red, green, and blue) to produce a white light source; two (yellow and blue) light-emitting diodes that can produce two different wavelength bands are placed in the same package, and are colored by color ( a combination of yellow light and blue light to produce a white light source; and a short-wavelength light-emitting diode capable of generating blue light, violet light or ultraviolet light in a package, and blue light, violet light or light generated by the light-emitting diode Ultraviolet light illuminates the phosphor, dye or light converting layer to produce a white light source. However, the white light source generated by the above three kinds of light-emitting elements tends to have a non-uniform intensity distribution of light of various colors in 201030110, and it is easy to cause problems such as poor color rendering and glare of the white light source. For example, if the intensity of the red light in the white light source is high, the white light source will be reddish or yellowish. In contrast, if the intensity of the blue light in the white light source is high, the white light source will be bluish. And it will make the white light source too glaring. SUMMARY OF THE INVENTION The main object of the present invention is to provide a filter coating material for a light-emitting element, which mainly comprises quinoline, poglione, fluorene and a fluorescent agent, and is used for filtering a light source generated by the light-emitting element. The filtered light source has a relatively uniform spectral distribution and color rendering. A secondary object of the present invention is to provide a filter coating for a light-emitting element, which can adjust the proportion of quinoline, polenone, hydrazine and a fluorescent agent in the filter coating according to the distribution of the light source generated by the light-emitting element. The filtered source is similar to the radiation spectrum of daylight. Another object of the present invention is to provide a filter material for a light-emitting element, which is mainly provided with a fluorescent agent in the filter paint, thereby converting part of the short-wavelength color light in the white light source into other wavelengths. Color light, while reducing the brightness loss caused by the filter coating when filtering the light source. Another object of the present invention is to provide a filter coating for a light-emitting element, wherein the filter coating is disposed on a transparent substrate and used to form a filter layer on the transparent substrate, and the thickness of the filter layer can be Controlled between 5 μm and 15/zm, so that the filter layer has good transparency and filtration efficiency. 201030110 A further object of the present invention is to provide a light-emitting component material, wherein the filter coating comprises acrylic Resin and thinner, and "coating the light-transmissive substrate coated with a filter coating to form a light-passing layer."

And the light source and the light source, the two-purpose layout. As shown in the figure, 'mainly set the filter coating on a light-transmitting layer', thereby forming a sound of the light on the transparent substrate 15. At least one light-emitting element 13 is disposed on the 151, for example, the light-emitting element 丨3 includes at least one light-emitting diode (LED), and the light-transmitting substrate 15 provided with the filter layer π is disposed on the pedestal 11 and/or The light-emitting element 13 is configured to pass through the light source L1 generated by the light-emitting element 13 and form a filter light source L2, wherein the light source L1 and the filter light source L2 are white light sources as seen by the naked eye. It is formed by a filter coating, wherein the filter coating mainly comprises Quinophthalone, Perynone, Anthraquinone and a fluorescent agent, for example, when the light-emitting element 13 is a 201030110 light-emitting diode. The content of the chlorinated material may be 4.6 to 2.1% by weight of the filter coating; the content of strontium may be Filtering paint 2. 3 to 1.3 weight • percentage percent; and fluorescent The content of the filter coating may be 0.82 to 0.48 weight percent of the filter coating. In actual use, the filter coating further comprises an acrylic resin and a diluent, wherein the content of the acrylic resin is 40 to 50 weight of the filter coating. Percentage, and the diluent may be an organic solvent such as butyl acetate, and the content of the dilute release agent (organic solvent) is 34 to 46 weight percent of the filter coating, and the use of acrylic resin and diluent will The filter layer 17 is coated and formed, and the filter layer 17 is formed on the transparent substrate 15. In an embodiment of the invention, the diluent (organic solvent) includes alcohol and can be transparently The material of the light substrate 15 adjusts the proportion of the alcohol in the diluent. Generally, the alcohol accounts for about 40 to 50% by weight of the diluent, in other words, the alcohol content is about 17 to 23 by weight of the filter coating. The ratio of 0%, thereby facilitating the formation of the filter and light layer 17 on the light-transmissive substrate 15. For example, when the material of the transparent substrate 15 is acrylic, the diluent (organic solvent) may include butyl acetate and an alcohol (ethanol or propanol), wherein the content of butyl acetate is 17 to 23 of the filter coating. The content of the alcohol (ethanol or propanol) is 17 to 23% by weight of the filter coating, whereby the surface of the transparent substrate 15 can be prevented from being corroded by the diluent and the smoothness of the surface of the transparent substrate 15 can be prevented. And transmittance. In an embodiment of the invention, an appropriate proportion of quinoline, poglione, hydrazine and a fluorescent agent may be mixed, and then placed in a drying oven having a vacuuming function 6 201030110, thereby purifying and Remove internal moisture. Finally, the purified quinoline, poglione, hydrazine and phosphor are mixed with acrylic resin and ground by a three-roller or high-speed mill. When used, the uniformly mixed quinoline, poglione, hydrazine, fluorescent agent and acrylic resin may be further mixed with a diluent, and disposed on the transparent substrate 15 by painting or spraying. The micro-temperature drying is then carried out, for example, at about 50-65 degrees Celsius. In the above description of the present invention, the weight percentages of the lincoln, the chlorin, the glory, the acryl, and the diluent mainly refer to the proportion of the above materials compared to the filter before drying and hardening. . When the filter coating is applied to the light-transmitting substrate 15 and dried, a filter layer 17 will be formed on the light-transmitting substrate 15. At this time, part of the material in the filter coating will be volatilized, such as a diluent (organic Solvents), quinoline, chlorphenone, hydrazine, phosphor, acrylic resin and diluent will account for the weight percentage of the filter coating. ❿ When filtering the light source L1 with the filter layer 17, except that the ratio of quinoline, poglione, hydrazine and phosphor in the filter coating affects the brightness and wavelength distribution of the filter source L2, the filter is filtered. The thickness 层 of the layer 17 also affects the light source L2 and the wavelength distribution. In a preferred embodiment of the invention, the thickness η of the filter layer 17 is between 5//m and 15 μm, so that the filter is filtered. Layer 17 also has good light transmittance and filtration effect. Of course, in practical applications, the quinoline 'bolinone in the filter coating can be adjusted according to the spectral distribution of the light source L1 generated by the light-emitting element 13 and the characteristics of quinoline, Polly_, antimony and the fluorescent agent itself. Proportion of green onion and fluorescing agent 201030110. In general, a light source with a wavelength of 520 nmi and 62 〇nm has a souther transmission rate to quinoline; a light source with a wavelength of 550 nm to 650 nm has a higher transmittance for poridinone; the wavelength is between 6 〇〇 nm and 7 〇. The light source of 〇nm has a relatively high transmittance for 蒽醌; while the short-wavelength color light (such as blue or green light) can be used to excite the luminescent agent' and produce long-wavelength colored light (such as red, yellow or orange). Light), thereby causing a phenomenon in which the light source L1 generated by the partial light-emitting elements 13 is red-shifted. The filter coatings include nano-grade high temperature and UV resistant quinoline, Polly mesh and onion, and make the calender coatings have wavelengths between 52〇11111 and 62〇nm, 550nm to 650nm and 600nra to 7〇〇nm. The light source has a high transmittance. In addition, the fluorescent agent in the filter coating can convert part of the short-wavelength color light in the light source u into a long-wavelength color light, and make the glare source u become a soft filter, the light source L2'. Therefore, the use of the filter paint will The illuminating device 13 can be used more widely in the use of illumination. The sky-members, such as the conventional technology, consist of two light-emitting diodes that can produce different color lights, such as LEDs that can generate red, green, and blue light in the same package. The light source_spectrum distribution generated by the red, green, and blue-mixing causes the hairpiece 13 to emit 2Q of the two light-emitting elements 13 is as shown by the curve a of the second figure. It can be seen from the curve a of FIG. 2 that among the light sources generated by the light-emitting element 13, the light source having a wavelength of 40 〇 nm to 48 〇 nm has a high intensity, and the color light intensity (1) having a length of 450 nm is about 4 a u. It is easy to cause the light source U to be too glaring. The New York fluorescein content can be in the range of 8 201030110 0. 65 weight percent, whereby the color light having a wavelength between 400 nm and 480 nm will excite the fluorescent agent when penetrating the filter layer 17 and Produces a light source with a wavelength greater than 480 nm'. For example, the phosphor may be a nanometer phosphor (Luminophor), and the phosphor includes rare earth and/or ions. The fluorescent agent is mainly used to convert the light energy with higher energy in the light source L1 into a lower energy color light, and the use of the fluorescent agent can not only reduce the proportion of the higher energy color light in the light source L1, so that the filtering light source L2 It is less likely to be too glaring, and it can also reduce the loss of light intensity caused by the light source L1 when penetrating the filter coating. The content of 蒽駆 蒽駆 3.5 3.5 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 weight percent, whereby the transmittance of the color light having a wavelength of 520 nm to 700 nm in the light source L1 can be effectively controlled. The light source L1 generated by the light-emitting element 13 will be filtered into the filter light source L2 after penetrating the filter layer 17, wherein the spectral distribution of the filter light source L2 is as shown in the curve b of FIG. 2, and the wavelength in the curve b is smaller than that shown in the figure. The color of the 450 nm is significantly reduced compared to the curve a, so the filter source L2 will be softer than the source L1. In addition, the spectrum of the curve b is uniformly distributed between the wavelengths of 450 nm and 700 nm, and the intensity of the colored light between the wavelengths of 450 nm and 700 nm is also greater than the curve a, so the brightness of the filtering light source L2 is not significantly higher than that of the light source L1. Falling, in other words, the light source L1 does not cause much loss of brightness during the process of penetrating the filter layer 17. In addition, from the distribution of the curve b in FIG. 2, it is also known that the distribution of the light of each color of the light source L2 of the filter 9 201030110 is equivalent, for example, the intensity of the light source L2 with a wavelength of 450 nm to 700 nm (I) Between 2. 5a. u. ' to 4. 5a. u., in other words, the filter source L2 will have better color rendering than the source L1. Referring to Figures 3 and 4, respectively, a schematic diagram of the construction of the filter coating applied to the light-emitting element of the present invention and a spectrum distribution diagram of the light source and the filtered light source are shown. As shown in the figure, at least one light-emitting element 23 is disposed mainly on the susceptor 11, for example, the light-emitting element 23 includes at least one light-emitting diode (LED), and the light-transmitting substrate 15 provided with the filter layer 27 can be disposed. It is disposed on the susceptor 11 and/or the illuminating element 23, thereby filtering the light source L3 generated by the illuminating element 23 and forming a filtering light source L4, wherein the light source L3 and the filtering source L4 are all white as seen by the naked eye. light source. In an embodiment of the invention, the light-emitting element 23 can be composed of two light-emitting diodes which can generate different colored lights as described in the prior art, and the light-emitting element 23 emits the light source L3 by mixing of different colored lights. The curve c of the fourth @图 is the spectral distribution of the light source L3 generated by the light-emitting element 23, and the curve d is the spectral distribution of the filtered light source L4 generated by the filtering of the filter layer 27. 5a. The light source (I) having a wavelength of 450 nm is about 4. 5a. u., and cause the light source L3 to be too glaring. The content of the fluorescent agent in the filter coating may be 0.73 weight percent of the filter coating, and the content of the quinoline in the filter coating may be 2.35 weight percent of the filter coating; the content of the polenone may be the filtration of the 201030110 light coating. 2重量百分比。 The content of the filter coating may be 2. 27 weight percent. It can be seen from the spectrum distribution of the curves a and c in the second and fourth graphs that the light source L3 generated by the light-emitting element 25 is at a wavelength relative to the light source u generated by the light-emitting element 13. The color light between 4 〇〇 nm and 480 nm has a higher distribution, so the proportion of the fluorescent agent in the filter layer 27 will be higher than the proportion of the fluorescent agent in the filter layer 17, for example, the fluorescene in the filter layer 27. The content of the photo-agent was 73 wt% of the filter coating, and the amount of the phosphor in the filter layer 17 was 0.65 wt% of the filter coating. In other words, when the distribution of the short-wavelength color light in the light source generated by the light-emitting element is high, it is necessary to draw the proportion of the glare agent in the luminescent paint. In addition, the brightness of the color light having a wavelength between 500 nm and 600 nm in the curve c is also higher than the curve a, so that the proportion of quinoline in the filter layer 27 can be made lower than the ratio of quinoline in the filter layer 17, for example, the filter layer 27 5重量百分比。 The content of the quenching material is 3. 5 weight percent of the filter coating. Moreover, the luminance of the color light having a wavelength between 650 nm and 700 nm in the curve c is lower than the curve a, so that the ratio of 蒽S Kun in the luminescent layer 27 is lower than the ratio of 蒽祗 in the filter layer 17, for example, filtering. The content of the smear of the filter layer is 1.77 weight percent of the filter coating. In the above embodiments of the present invention, the proportions of quinoline, poglione, hydrazine, and fluorescer in the filter coating are adjusted according to the spectral distribution of the light source L1/L3 generated by the illuminating element 13/23. The filter light source 11 201030110 L2/L4 has better color rendering properties, and can effectively improve the problem that the light source L1/L3 is too glare. In addition, the proportion of quinoline, poglione, hydrazine and phosphor in the filter coating can be adjusted according to the requirements of use, and the spectral distribution of the filter source -L2/L4 can meet the needs of users. Of course, in the present invention, the curve a/c of the light source L1/L3 generated by the light-emitting elements 13/23 is mainly taken as an illustrative embodiment. However, the type of the light-emitting element and the curve of the light source are not limited to the above two in actual use. For example, the ratio of quinoline, poglione, hydrazine and phosphor in the filter layer can be changed, so that the filter layer can also be applied to a luminescent element that emits a luminescent powder with a short-wavelength source to produce a white light source. . The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the variations, modifications, and modifications of the shapes, structures, features, and spirits described in the claims of the present invention. All should be included in the scope of the patent application of the present invention. φ [Simplified description of the drawings] Fig. 1 is a schematic view showing the construction of the filter coating of the present invention applied to a light-emitting element.
