Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ultraviolet light therapy, and particularly relates to a method for realizing UVB lamp bead screening and vitamin D3 synthesis promotion. BACKGROUND

[0002] Vitamin D3 is a nutrient essential for the life of higher animals, and vitamin D3 is crucial for bone health, but the phenomenon of vitamin D3 deficiency is widespread. In a study covering 2173 Chinese residents, researchers found that 94.6% of people had varying degrees of vitamin D3 deficiency. Although vitamin D3 can be supplemented through sun exposure and food in daily life, there is generally insufficient sunlight exposure due to lifestyle, work, and other reasons. Coupled with short winter daylight hours and weak ultraviolet light, winter and spring lack of outdoor activities, and diseases caused by vitamin D3 deficiency among urban residents are increasing year by year. The existing phototherapy technology mainly selects to use a wavelength of 280-320 nm (UVB), and UVB ultraviolet light has erythema effect on the human body, and can promote the effective synthesis of vitamin D3 and mineral metabolism in the body through ultraviolet irradiation.

[0003] Although UVB phototherapy technology has shown important application value in promoting vitamin D3 synthesis, the existing method still has significant technical shortcomings: the screening of lamp beads lacks hierarchical precise control of parameters such as peak wavelength, half-wave width, and light radiation flux, and the detection equipment has not established a standardized benchmarking mechanism, resulting in the mixing of unqualified lamp beads affecting the effectiveness of the spectrum; the layout of the lamp bead matrix relies mainly on experience design, without quantitative optimization in combination with the size of the area light source, the driving current, and the light chamber structure, which easily causes uneven energy distribution in the irradiation area; the spectrum processing does not effectively eliminate the low-intensity noise band, and the synthesis efficiency calculation does not establish a precise model coupled with the actual spectral characteristics, resulting in a deviation between the theoretical efficiency and the actual effect. With the intensification of the problem of vitamin D3 deficiency in the process of urbanization and the rapid growth of the market demand for artificial phototherapy equipment, the shortcomings of the existing technology in terms of spectral energy utilization, equipment compatibility, and synthesis efficiency stability are increasingly prominent, and a systematic solution covering lamp bead screening, layout design, spectrum optimization, and efficiency calculation is urgently needed to break through the traditional technical bottlenecks and improve the practicality and reliability of phototherapy equipment. SUMMARY

[0004] In view of the above technical problems existing in the existing UVB phototherapy technology, the application provides a method for realizing UVB lamp bead screening and vitamin D3 synthesis promotion.

[0005] To solve the above technical problems, the technical scheme adopted by the application is as follows:

[0006] A method for realizing UVB lamp bead screening and vitamin D3 synthesis promotion, comprising:

[0007] Parameter selection of UVB lamp bead: the parameters of UVB lamp bead are divided into key parameters, main parameters and general parameters;

[0008] Inspection standard of UVB lamp bead: including inspection equipment, inspection equipment standard, inspection operation process and inspection error analysis;

[0009] Setting of UVB lamp bead matrix: adjusting the number of lamp beads according to the size of the area light source, and adjusting the matrix arrangement according to the driving current and the light chamber;

[0010] De-noising of UVB spectrum: using background light removal method to determine the effective wavelength range of the spectrum;

[0011] Calculation of vitamin D3 synthesis efficiency: based on the effective wavelength range of UVB spectrum and the efficiency model of vitamin D3 synthesis efficiency.

[0012] The key parameters include peak wavelength, half wave width and 1 / 10 wave width, wherein the peak wavelength is 297nm±3nm, the half wave width is 9-12nm, and the 1 / 10 wave width is ≤25nm, and if any parameter is unqualified, the lamp bead is unqualified.

[0013] The main parameters include light radiation flux and grading, and under the rated 10mA driving current, the light radiation flux range is 1.6mW-4.0mW, and the grading is (N+0.1)mW, wherein N is a non-negative integer multiple of 0.05, and the allowable error is ≤±10%, and if any parameter is unqualified, the lamp bead is unqualified.

[0014] The general parameters include rated driving current (10mA±5%), maximum driving current (100mA±5%), driving voltage range (4.0V-6.0V), light emitting angle (≥110°), epitaxial chip (1020 or 2020) and packaging (3030 or 3535), which need to be analyzed in combination with the driving circuit or be easy to realize by the supplier.

[0015] The inspection equipment is an ultraviolet light detection integrating sphere, and the core device includes a standard device and a spectrometer, which requires that the wavelength detection range includes 200nm-400nm, the spectral resolution is ≤0.1nm, and the minimum order of magnitude of the radiation flux is ≤0.1mW.

[0016] The inspection equipment standard is to compare the spectral parameters of the integrating sphere and the sorting machine of the supplier and the user, to ensure that the lamp bead supply parameters are consistent with the demand parameters.

[0017] In the UVB lamp bead matrix, the distance between the lamp beads is the distance between the center points of the adjacent rows and columns (K+0.5cm), wherein K is a non-negative integer multiple of 0.1, and the shortest distance between the edge lamp bead and the edge of the lamp plate is (P+0.3)cm, wherein P is a non-negative integer multiple of 0.1.

[0018] In the UVB spectral denoising, 0.1 μW / cm² is used as the light irradiance limit value, and wavelengths below this value are considered noise; the starting point of spectral denoising is the minimum wavelength at which the light irradiance is continuously greater than or equal to the limit value, and the ending point is the maximum wavelength.

[0019] The theoretical effective wavelength range in the calculation of vitamin D3 synthesis efficiency is 263nm to 312nm. The final effective wavelength range is the intersection of the denoised spectrum and the theoretical effective wavelength range. The calculation formula is as follows:

[0020]

[0021] in, Indicates the final effective wavelength range. For the minimum wavelength, This is the maximum wavelength.

[0022] The formula for calculating the vitamin D3 synthesis efficiency is as follows:

[0023] in This represents the percentage of vitamin D3 synthesized within the final effective wavelength range for vitamin D3 synthesis efficiency. It is the ultraviolet radiation intensity at wavelength λ. It is a wavelength of λ Vitamin D3 synthesis efficiency weighted. This refers to the wavelength bandwidth.

[0024] Compared with the prior art, the beneficial effects of this invention are:

[0025] 1. This invention constructs a multi-level screening system by scientifically dividing UVB lamp bead parameters into key parameters, main parameters, and general parameters. The strict limitations on peak wavelength (297nm±3nm), half-width (9~12nm), and 1 / 10 wavelength (≤25nm) among the key parameters ensure that the lamp bead emission spectrum is concentrated in the core effective wavelength band for vitamin D synthesis, eliminating unqualified products with large spectral deviations at the source. The main parameters, including the graded control of light radiant flux (1.6mW~4.0mW, graded accuracy 0.1mW) and the standardization of general parameters such as driving current and voltage, not only guarantee the stability of the lamp bead's luminous performance but also adapt to mainstream driving circuit designs, improving equipment compatibility.

[0026] 2. This invention employs an integrating sphere for ultraviolet light detection as the core testing equipment. Its wavelength detection range (200nm~400nm), spectral resolution (≤0.1nm), and radiant flux detection accuracy (≤0.1mW) meet the requirements for fine UVB spectral detection. Through a supplier-user equipment benchmarking mechanism, systematic errors from different testing platforms are eliminated, ensuring that the LED chip supply parameters perfectly match actual application requirements and avoiding fluctuations in vitamin D3 synthesis efficiency due to parameter drift. The testing operation process and error analysis further enhance screening reliability, providing quality assurance for large-scale production.

[0027] 3. This invention dynamically adjusts the number of LED beads based on the size of the surface light source and optimizes the matrix arrangement according to the driving current and light chamber structure. Through quantitative design of the LED bead spacing (K+0.5cm) and edge distance (P+0.3cm), it achieves a uniform distribution of ultraviolet radiation intensity within the irradiation area. This layout effectively avoids the light decay problem at the edge of traditional light panels, ensuring that the UVB energy received by each point on the surface of the irradiated object is balanced, providing a stable light environment for vitamin D3 synthesis, and is especially suitable for the engineering application of large-area phototherapy equipment.

[0028] 4. This invention uses 0.1 μW / cm² as the limit value for light irradiance and determines the effective spectral range through continuous threshold detection, eliminating low-intensity noise bands. This ensures that the final effective wavelength range is precisely focused on the intersection of the theoretical synthesis range (263nm~312nm) and the actual spectrum. This noise reduction method effectively filters out ineffective ultraviolet radiation, concentrating energy on the key wavelengths for vitamin D3 synthesis. This reduces energy consumption while avoiding potential harm to the human body from unnecessary wavelengths.

[0029] 5. This invention utilizes an integral calculation model based on the weighted value of ultraviolet irradiation intensity and vitamin D3 synthesis efficiency to quantify the contribution of different wavelengths to the synthesis efficiency through mathematical modeling. This model not only provides a quantifiable efficiency evaluation standard for LED selection but also guides the spectral optimization design of phototherapy equipment—dynamically optimizing the energy distribution within the effective wavelength range by adjusting LED matrix parameters or driving current to maximize vitamin D3 synthesis efficiency. Practical testing has verified that phototherapy equipment using this method achieves a synthesis efficiency increase of over 30% and an energy utilization rate increase of 25% compared to traditional methods, significantly enhancing the practicality and cost-effectiveness of UVB phototherapy technology.

[0030] This technology system provides a complete approach to improving the efficiency of vitamin D3 screening. In a controlled indoor environment, it can precisely simulate the key spectral components in sunlight that promote vitamin D3 synthesis, overcoming the limitations of natural sunlight due to seasonal and geographical constraints. It is particularly suitable for scenarios with insufficient sunlight in winter and long-term indoor office work, providing an efficient and safe technical solution for preventing and improving vitamin D3 deficiency-related diseases (such as osteoporosis and weakened immunity), with significant social value and economic benefits.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. These descriptions are only for further illustrating the features and advantages of the present invention, and not for limiting the claims of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0040] This invention provides a method for screening UVB lamp beads and improving vitamin D3 synthesis, which consists of selecting UVB lamp bead parameters, setting UVB lamp bead inspection standards, setting UVB lamp bead matrix, denoising UVB spectrum, and calculating vitamin D3 synthesis efficiency.

[0041] The UVB lamp bead parameters of this invention include key parameters, main parameters, and general parameters. Key parameters serve as crucial indicators of whether a UVB lamp bead is qualified; failure to meet any of these parameters will be used as the basis for determining whether the UVB lamp bead is unqualified. Key parameters include peak wavelength, half-width at half-maximum (WWHM), and 1 / 10 wavelength. The peak wavelength is 297nm ± 3nm, the WWHM is 9–12nm, and the 1 / 10 wavelength is no greater than 25nm. The main parameters, as key indicators of the safety and reliability of the electrical and optical performance conversion of UVB lamp beads, need to be analyzed in conjunction with the specific drive circuit to determine the numerical range, error range, and allowable failure rate of the main parameters. Taking into account the numerical range, error range, and allowable failure rate of each main parameter, the failure of any one main parameter as a whole will be used as the basis for judging the UVB lamp bead as unqualified. The main parameters include: luminous flux and luminous flux grading; under the rated 10mA drive current, the luminous flux range is 1.6mW to 4.0mW, the luminous flux grading is (N+0.1)mW, N is a non-negative integer multiple of 0.05, and the allowable error is no higher than ±10%. General parameters, which are not critical for the safe and stable operation of UVB lamp beads, need to be analyzed in conjunction with the specific drive circuit to determine their numerical range, error range, and allowable non-conformity rate. These parameters are often easily achievable by suppliers and are not considered R&D challenges. However, considering the overall non-conformity of each general parameter, the overall non-conformity needs to be analyzed and evaluated based on actual use before being used as the basis for determining the quality of the UVB lamp beads. General parameters include rated drive current, maximum drive current, drive voltage range, drive voltage levels, emission angle, epitaxial chip size, and package size. For example, the rated drive current is 10mA±5%, the maximum drive current is 100mA±5%, the drive voltage range is 4.0V~6.0V, the drive voltage levels are (M+0.1)V, where M is a non-negative integer multiple of 0.05, the allowable error is no higher than ±5%, the emission angle is no less than 110°, the epitaxial chip uses 1020 or 2020, and the package uses 3030 or 3535.

[0042] The inspection standards for UVB lamp beads of this invention include UVB lamp bead inspection equipment, UVB lamp bead inspection equipment benchmarking, UVB lamp bead inspection operation procedures, and UVB lamp bead inspection error analysis. The UVB lamp bead inspection equipment is an integrating sphere for ultraviolet light detection, with core components being a standard and a spectrometer. It requires the inspection wavelength range to include the 200nm–400nm UVB band, a spectral wavelength resolution of no more than 0.1nm, and a minimum spectral radiant flux of no more than 0.1mW. The UVB lamp bead inspection equipment benchmarking refers to calibrating the integrating sphere or sorting machine used by the UVB lamp bead supplier with the integrating sphere used by the UVB lamp bead user for spectral parameters to ensure consistency between the supplied and required parameters. The inspection process for UVB lamp beads is agreed upon by both the UVB lamp bead user and the UVB lamp bead supplier, and an integrating sphere operating procedure is developed. This procedure ensures that both parties adhere to a unified operating process when inspecting UVB lamp beads, preventing errors caused by inconsistencies in the inspection process. The inspection error analysis for UVB lamp beads includes objective errors (i.e., equipment errors and benchmarking errors) and subjective errors (i.e., inspection method errors, environmental errors, human errors, etc.). Equipment errors are objective errors, which can be eliminated, but can be relatively reduced through equipment benchmarking. Inspection method errors are subjective errors, which can be eliminated through consistency in inspection methods. Environmental errors are subjective errors, which can be largely reduced through benchmarking of environmental requirements. Human errors are subjective errors, which can be reduced through operator training and assessment. By analyzing the inspection errors of UVB lamp beads, the magnitude of each error and the proportion of influencing factors are determined, facilitating effective error control and elimination. Combined with the actual product tolerance coefficient, practical and efficient standards suitable for UVB lamp bead inspection are identified.

[0043] The UVB lamp bead matrix 1 of the present invention is configured as follows: Figure 1 As shown, the UVB lamp matrix 1 includes UVB lamps 1-1, UVB lamp panels 1-2, UVB lamp spacing 1-3, and distances 1-4 between UVB lamps and the edges of the UVB lamp matrix. UVB lamps 1-1 are soldered onto UVB lamp panels 1-2, serving as point light sources in a regularly distributed matrix, generating a UVB spectrum capable of efficiently synthesizing vitamin D3. The UVB lamp spacing 1-3 is the distance between the center points of adjacent lamps in rows and columns, which is (K+0.5) cm, where K is a non-negative integer multiple of 0.1. The distances 1-4 between UVB lamps and the edges of the UVB lamp matrix are the shortest horizontal and vertical distances between the outermost UVB lamp and the adjacent UVB lamp panel 1-2, which is (P+0.3) cm, where P is a non-negative integer multiple of 0.1. The number of UVB lamps, the UVB lamp spacing 1-3, and the distances 1-4 between UVB lamps and the edges of the UVB lamp matrix form the regularity of the lamp matrix.

[0044] The UVB spectrum denoising of the present invention, such as Figure 2 As shown, UVB spectrum 2 includes the irradiance intensity limit value 2-1 for spectral denoising, the starting point 2-2 for spectral denoising, and the ending point 2-3 for spectral denoising. The irradiance intensity limit value 2-1 for spectral denoising is the intensity limit value of spectral noise. Based on the current market's smallest irradiance intensity testing instrument, the accuracy is 0.1 μW / cm². 2 The light irradiance intensity limit for spectral noise reduction, 2-1, is set to 0.1 μW / cm. 2 Wavelengths below this value are treated as noise and optimized away. The starting point 2-2 of spectral denoising is the minimum wavelength corresponding to the continuous light irradiance intensity of UVB spectrum 2 not lower than the light irradiance intensity limit value 2-1 of spectral denoising. The ending point 2-3 of spectral denoising is the maximum wavelength corresponding to the continuous light irradiance intensity of UVB spectrum 2 not lower than the light irradiance intensity limit value 2-1 of spectral denoising. The starting point 2-2, the ending point 2-3 of spectral denoising, and the intermediate wavelengths constitute the effective wavelength range of the UVB spectrum.

[0045] The calculation of vitamin D3 synthesis efficiency in this invention, such as... Figure 3 As shown, the pure UVB spectrum 3 (i.e., the UVB spectrum after noise reduction) includes the starting point 3-1 and the ending point 3-2 of the effective wavelength range. Figure 4 As shown, the effective range of the pure UVB spectrum is selected according to Table 1 of the paper "CIE 174:2006: ACTION SPECTRUM FOR THE PRODUCTION OF PREVITAMIN D3 IN HUMAN SKIN", where the vitamin D3 synthesis efficiency is no less than 0.1 as the limit. Therefore, the starting point 3-1 of the effective wavelength range is 263 nm, and the ending point 3-2 is 312 nm. The range of pure UVB spectrum 3 is 263 nm to 312 nm. The calculation of vitamin D3 synthesis efficiency requires finding the intersection of the effective wavelength range of the denoised UVB spectrum 2 and the pure UVB spectrum 3 to obtain the final effective wavelength range of vitamin D3 synthesis efficiency. The final effective wavelength range of vitamin D3 synthesis efficiency includes the minimum wavelength. Maximum wavelength And the intermediate wavelength, the calculation formula is:

[0046]

[0047] in, Indicates the final effective wavelength range. For the minimum wavelength, This is the maximum wavelength.

[0048] The formula for calculating the efficiency of vitamin D3 synthesis is:

[0049] in This represents the percentage of vitamin D3 synthesized within the final effective wavelength range for vitamin D3 synthesis efficiency. It is the ultraviolet radiation intensity at wavelength λ. It is a wavelength of λ Vitamin D3 synthesis efficiency weighted. This refers to the wavelength bandwidth.

[0050] This invention relates to a method for screening UVB lamp beads and enhancing vitamin D3 synthesis. It aims to provide an innovative method that can meet the requirements of efficient vitamin D3 enhancement, and to provide guidance for the verification of experiments on efficient vitamin D3 synthesis using UVB spectroscopy, as well as for medical device R&D and manufacturers to study products that utilize UVB spectroscopy for efficient vitamin D3 synthesis.

[0051] The above description only illustrates the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes should be included within the protection scope of the present invention.
