Description

Technical Field

[0001] The invention belongs to the technical field of health care, and in particular relates to a composite artificial lighting system for supplementing vitamin D and calcium. Background Art

[0002] Vitamin D and calcium are key nutrients for maintaining human bone health and multiple physiological functions. Vitamin D helps promote intestinal absorption of calcium, which is the main component of bones and teeth. In modern lifestyles, due to factors such as indoor work, seasonal changes, air pollution and sun protection habits, people often find it difficult to get enough ultraviolet (UV) exposure through natural sunlight, which affects the synthesis of vitamin D in the body. In addition, insufficient calcium intake and absorption are also common problems, especially among the elderly, children and patients with specific diseases.

[0003] To address this problem, existing technologies offer a variety of solutions, including oral vitamin D and calcium supplements, ultraviolet therapy devices, and artificial lighting systems. However, these methods have some limitations:

[0004] Oral supplements: Although convenient, their absorption effect is limited and the effects may vary due to individual differences. Long-term excessive intake may also bring health risks.

[0005] Ultraviolet therapy equipment: UVB radiation can effectively promote the conversion of 7-dehydrocholesterol into vitamin D3 in the skin, which then generates the active form 1,25-dihydroxyvitamin D through metabolic pathways in the body. This process is a key mechanism for promoting bone health and calcium absorption. In addition, the UVB band is specific to the production of vitamin D. Experiments with artificial UVB light sources can significantly improve human vitamin D levels, further verifying the effectiveness of this band. Existing equipment can provide ultraviolet rays of specific wavelengths to promote the synthesis of vitamin D, but these devices are usually used in medical scenarios, are complex to operate, and need to be used under the supervision of professionals.

[0006] The auxiliary effect of infrared rays on calcium absorption: Infrared radiation can penetrate deep into the skin, enhance blood circulation and cell metabolism, and thus indirectly support the absorption and utilization of calcium.

[0007] Artificial lighting systems: Some lighting systems on the market can simulate natural light and provide a comfortable indoor light environment, but they are limited in their effectiveness in promoting vitamin D synthesis and calcium absorption.

[0008] Although a number of achievements related to promoting vitamin D synthesis have been made public, they usually focus on a single solution, such as UVB radiation or red light irradiation alone, without considering the combined supplementation of vitamin D and calcium. In addition, continuous high-intensity UVB light and infrared irradiation may cause damage to the skin. Intermittent lighting design (such as pulsed light) can not only increase the effective light intensity, but also reduce potential safety hazards to the skin. This design can make up for the problem of weak UVB light penetration, while avoiding erythema and skin damage that may be caused by long-term high-intensity irradiation.

[0009] Therefore, it is necessary to develop a composite artificial lighting system that can combine the advantages of different light sources and act on the skin in a safe and effective manner to promote the synthesis of vitamin D and the absorption of calcium, so as to achieve a more comprehensive nutritional supplement effect. The present invention aims to provide such a system, which can simulate the natural light environment and provide light of a specific wavelength in the form of pulses to promote the supplementation of vitamin D and calcium safely and efficiently. Summary of the invention

[0010] The present invention aims to provide a safe and efficient composite artificial lighting system for supplementing vitamin D and calcium, so as to overcome the risk of vitamin D and calcium deficiency faced by people, especially those who work in indoor environments for a long time, due to lack of sunlight.

[0011] The composite artificial lighting system for vitamin D and calcium supplementation provided by the present invention combines LED white light, ultraviolet (UVB) and / or infrared (IR) light to safely and efficiently promote the synthesis of vitamin D and the absorption of calcium. Specifically, the system is composed of LED white light beads, LED ultraviolet lamp beads and / or LED infrared lamp beads, as well as lamps, lampshades, power supplies, and control circuits; wherein:

[0012] The LED white light lamp beads are used to provide visible light required for daily lighting to ensure that the indoor environment is well-lit and comfortable. Preferably, in a home environment, the illumination can reach 300-500 lux (lx), and in an office environment, the illumination can reach 500-1000 lux (lx).

[0013] The LED ultraviolet lamp beads are used to emit ultraviolet rays of a specific wavelength to promote the synthesis of vitamin D in the skin. Preferably, the peak wavelength of the ultraviolet lamp beads is the UVB spectrum (303-310nm).

[0014] The LED infrared lamp beads are used to emit infrared rays to promote blood circulation and cell metabolism, and indirectly support the absorption and utilization of calcium. Preferably, the peak wavelength of the LED infrared lamp beads is 750-850nm (near infrared band).

[0015] The LED ultraviolet lamp beads and / or infrared lamp beads are located at the center of the lighting fixture, and the lampshade is a purple light-transmitting glass, which is used to prevent the single LED from being seen from the outside of the lamp while ensuring the effective transmission of UVB radiation.

[0016] The LED white light beads are located on the periphery of the LED ultraviolet lamp beads and / or infrared lamp beads.

[0017] The power supply provides electrical energy for the system; the control circuit is used to control the working state of the LED white light lamp beads, LED ultraviolet lamp beads and / or LED infrared lamp beads, such as controlling the opening mode, luminous intensity, etc.

[0018] Further:

[0019] In the composite lighting system, the LED ultraviolet lamp beads and / or infrared lamp beads are irradiated and output in the form of pulsed light to increase the instantaneous peak light intensity to compensate for the problem of weak ultraviolet light penetration ability, while avoiding damage to the skin, eyes, etc. caused by long-term strong ultraviolet and / or strong infrared irradiation.

[0020] In the composite lighting system, the LED white light beads and the LED ultraviolet lamp beads and / or LED infrared lamp beads are switched on and off by two different circuits, so that the lighting time can be adjusted manually to meet the needs of different users.

[0021] A focusing lens is arranged below the ultraviolet and / or infrared light beads in the lamp, so that the ultraviolet and / or infrared light is mainly irradiated on the part below the lamp, and the corresponding diffusion angle below the lamp can be 5-45°.

[0022] The composite artificial lighting system of the present invention not only provides an effective means of vitamin D and calcium supplementation, but also ensures convenience and safety of use through intelligent control and safety design, thereby meeting the demand for healthy lighting in modern indoor environments.

[0027] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0028] See also Figure 1-Figure 3 The composite artificial lighting system provided by the present invention includes: LED ultraviolet lamp beads and / or infrared lamp beads 1, ultraviolet light transparent glass lampshades 2, LED white light lamp beads 3, and also includes a power supply and a control circuit.

[0029] The lighting fixture is composed of ultraviolet lamp beads and / or infrared lamp beads 1 located in the center, and LED white light lamp beads 3 arranged on the periphery; Figure 1 Preferably, the white light LED is generated by a blue LED chip exciting a yellow phosphor, wherein the wavelength of the blue light emitted by the blue LED chip is between 450-470nm, and the wavelength of the yellow light emitted by the yellow phosphor is between 570-580nm.

[0030] Specifically, the lighting fixtures are installed directly above the office area, and the LED white light beads can provide the visible light required for daily lighting, ensuring that the indoor environment is well-lit and comfortable.

[0031] Specifically, the LED white light lamp beads are composed of a lamp board and a uniform light board. The LED lamp board is welded with two LED lamp beads with color temperatures of 4500K and 4000K respectively. The rated power of a single lamp bead is 0.5W and the package is 3535. The illumination of a single LED light source is adjustable between 300-1000lx.

[0032] Specifically, the LED ultraviolet lamp beads emit ultraviolet rays of a specific wavelength to promote the synthesis of vitamin D in the skin. Preferably, the wavelength of the ultraviolet LED lamp beads is 305nm.

[0033] Specifically, the LED infrared lamp beads emit infrared rays to promote blood circulation and cell metabolism, and indirectly support the absorption and utilization of calcium. Preferably, the wavelength of the infrared LED lamp beads is 850nm.

[0034] In the composite lighting system, ultraviolet and / or infrared irradiation is output in the form of pulsed light. Specifically, in the composite lighting system, the AC power supply (220V) is rectified and stabilized to provide a DC voltage to drive different types of LED lamp beads. Among them, the visible light LED lamp beads directly output stable continuous light through the LED drive circuit to meet conventional lighting needs. The ultraviolet and / or infrared LED lamp beads are controlled by the LED drive circuit and the pulse modulation circuit (PWM) to output in the form of pulsed light. The working process of the system is as follows Figure 3As shown. First, the AC power supply is rectified and stabilized to generate a stable DC voltage, which is provided to the LED driving circuit. For the output part of ultraviolet and / or infrared light, the pulse width modulation (PWM) circuit generates a pulse waveform of a specific frequency and duty cycle according to a preset control signal, adjusts the on and off state of the ultraviolet and / or infrared LED lamp beads, and forms a pulse light output. Preferably, the core purpose of this pulse light output design is to increase the instantaneous peak light intensity of each pulse and improve the penetration ability of ultraviolet light, thereby effectively compensating for the problem of weak penetration ability of ultraviolet light in certain materials or media. At the same time, compared with continuous strong light irradiation, intermittent pulse light output can avoid the possible damage to the skin caused by long-term strong ultraviolet light and / or strong infrared, and improve the safety and applicability of the system. Through such a composite design, the present invention realizes the collaborative lighting function of visible light and ultraviolet and / or infrared light, which not only meets the application requirements of multiple scenarios, but also takes into account the light output efficiency and safety of use.

[0035] The LED ultraviolet lamp beads and / or LED infrared lamp beads are output in a pulsed manner. Specifically, the instantaneous peak light intensity of the ultraviolet light can be adjusted through a PWM circuit to improve the penetration ability of the ultraviolet light and reduce potential damage to the skin; at the same time, the frequency and duty cycle can also be accurately adjusted;

[0036] The composite lighting system also includes a data storage unit for recording the user's irradiation time and the accumulated ultraviolet light dosage, and an alarm device for reminding the user to appropriately adjust the irradiation time;

[0037] In the composite lighting system, the shape of the lamp is circular, elliptical or polygonal, and the LEDs can be arranged inside the lamp in any pattern as required;

[0038] In the composite lighting system, the lamp further includes a diffuser to prevent individual LEDs from being seen from outside the lamp, and utilizes UV-transmitting glass to ensure effective transmission of UVB radiation.

[0039] Specifically, the UV LED lamp beads and / or infrared LED lamp beads are set to work in pulse mode with a pulse width of 200ms and an interval of 2 seconds to ensure sufficient instantaneous peak light intensity while reducing potential damage to the skin.

[0040] Specifically, in the composite lighting system, the LED hundred-light lamp beads and the LED ultraviolet lamp beads and / or the LED infrared lamp beads are switched on and off by at least two different circuits, so that the lighting time can be adjusted manually to meet the needs of different users.

[0041] Specifically, a hemispherical lampshade is designed, which is made of heat-resistant plastic and coated with reflective material on the inside to ensure effective distribution of light.

[0042] Specifically, Figure 3 The medium power module is a 220V / AC to 36V / DC power supply with a rated current of 3A. It supplies power to the drive module and also provides power to the PWM module.

[0043] A light sensor is integrated into the system to automatically reduce the light intensity or turn off the lamp beads when it detects that the light intensity of the UV and / or infrared LED lamp beads exceeds the safety threshold.

[0044] An emergency stop button is designed in the system so that users can immediately stop the operation of all LED lamp beads when they feel unwell.

[0045] The above is a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
