Description

Technical Field

[0001] The present invention relates to the technical field of LED lighting, and particularly to an illumination light source, device and system that can promote human blood sugar metabolism. Background Art

[0002] Hyperglycemia refers to the concentration of glucose (i.e., blood sugar) in the blood exceeding the normal range. Being in a hyperglycemic state for a long time can cause damage to multiple organs such as the cardiovascular system, nervous system, kidneys, and eyes, and increase the risk of various diseases. Currently, the methods for controlling blood sugar mainly include two categories: non-drug means and drug treatment. Non-drug means such as dietary adjustments and weight loss through exercise are effective, but they are often challenging to implement. For many people, strictly following a diet plan or continuously exercising is not easy, and even if weight loss is achieved in the short term, it is easy to regain weight if a healthy lifestyle is not maintained afterwards. Drug treatment methods include oral hypoglycemic drugs and insulin injections, etc. Although these methods can help control blood sugar levels, they may also be accompanied by side effects or medication restrictions, such as gastrointestinal discomfort, diarrhea, and nausea.

[0003] Chinese patent application with publication number CN119258408A discloses a wearable light hypoglycemic device, system and eye mask. The wearable light hypoglycemic device includes: a wearing unit for the user to wear; an illumination unit for projecting red light onto the human eye; a driving unit for supplying power to the illumination unit; and a control unit for adjusting the light emitting mode of the illumination unit according to a preset regulation scheme. The preset regulation scheme is to perform several illuminations within a preset time, and there is a preset time interval between adjacent illuminations. The present invention can emit red light waves of a specific wavelength band to the human eye according to the preset regulation scheme, directly activate the photosensitive retinal ganglion cells ipRGCs, transmit signals through a series of nuclei in the optic nerve to the hypothalamus and medulla oblongata, and finally act on the peripheral brown adipose tissue BAT through the sympathetic nerve, affecting the blood sugar metabolism ability, thereby achieving the blood sugar control effect. However, when using this light hypoglycemic device for blood sugar control, the user cannot perform other activities that require visual participation. Summary of the Invention

[0026] Example 1 This example provides an illumination light source that can promote human blood glucose metabolism. The illumination light source is composed of a number of white light LEDs and a number of red light LEDs. The illumination color temperature of the illumination light source is lower than the preset color temperature.

[0027] Preferably, 1000K ≤ the illumination color temperature of the illumination light source ≤ 4500K. Refer to Figure 1 , the peak wavelength of the optical power distribution of the illumination light source is located in the range of 630 - 700nm.

[0028] Preferably, the light color ratio of the illumination light source: the proportion of blue light < 5.7%, the proportion of red light > 20%. In the light color ratio of the illumination light source, when increasing the proportion of blue light and decreasing the proportion of red light, the color temperature of the illumination light source increases. In the light color ratio of the illumination light source, when decreasing the proportion of blue light and increasing the proportion of red light, the color temperature of the illumination light source decreases.

[0029] Preferably, the optical power distribution of the illumination light source satisfies: 400 - 475nm, the relative optical power value < 0.80mW / nm; 640 - 650nm, the relative optical power value > 0.80mW / nm; 650 - 660nm, the relative optical power value > 0.75mW / nm; 660 - 670nm, the relative optical power value > 0.70mW / nm; 670 - 680nm, the relative optical power value > 0.65mW / nm; 680 - 690nm, the relative optical power value > 0.60mW / nm; 690 - 700nm, the relative optical power value > 0.55mW / nm; 700 - 780nm, the relative optical power value > 0.10mW / nm.

[0030] The optical power of the illumination light source at 400 - 475nm increases with the increase of the illumination color temperature of the illumination light source.

[0031] For the illumination light source with a color temperature below 3500K, its relative optical power value at 400 - 475nm is always less than 0.80mW / nm. For the illumination light source with a color temperature in the range of 3500K - 4500K, through polycrystalline packaging, the relative optical power value of the blue light at 400 - 475nm in the white light LED can be reduced to be less than 0.80mW / nm.

[0032] The optical power of the illumination light source in the range of 640 - 780 nm increases as the color temperature of the illumination light source decreases. In this embodiment, through the combination of a white LED and a red LED, the optical power distribution of the illumination light source in the range of 640 - 780 nm meets the aforementioned requirements. Preferably, the emission wavelength of the red LED in this embodiment is at least one of 640 - 780 nm. Preferably, the red LED can be a single-wavelength red LED or a wide-spectrum red LED excited by blue light. Preferably, when the illumination color temperature of the white LED is 3500 - 4500 K, the white LED is a white LED with a dual-crystal or multi-crystal package.

[0033] Preferably, there are three combination schemes in this embodiment for combining a white LED and a red LED to make the optical power distribution of the illumination light source in the range of 640 - 780 nm meet the aforementioned requirements.

[0034] The first combination scheme is: the combination of a white LED and at least one red LED with single-wavelength emission. For example, the combination of a white LED and a red LED with an emission wavelength of 690 nm; the combination of a white LED and a red LED with an emission wavelength of 700 nm; the combination of a white LED and red LEDs with emission wavelengths of 660 nm and 710 nm; the combination of a white LED and red LEDs with emission wavelengths of 650 nm, 700 nm, and 730 nm, etc.

For example, the combination of a white LED and a red LED with an emission band of 600 - 710 nm; the combination of a white LED and a red LED with an emission band of 630 - 710 nm, etc.

[0036] The third combination scheme is: the combination of a white LED and at least one red LED with single-wavelength emission and at least one wide-spectrum red LED excited by blue light. For example, the combination of a white LED and a red LED with an emission wavelength of 700 nm and a red LED with an emission band of 630 - 710 nm, etc.

[0037] Preferably, when at least two red LEDs with different emission wavelengths are used among the several red LEDs configured in the illumination light source, the wavelength difference between any two red LEDs is ≥ 30 nm.

[0038] Existing research has shown that red light can promote blood glucose metabolism through the visual system. Red light therapy is non-invasive and has no side effects, making it suitable for long-term use, especially for people who cannot adhere to a strict diet or exercise. The lighting source provided in this embodiment is composed of a white light LED and a red light LED, and the color temperature of the illumination light of the lighting source is limited. While ensuring the promotion effect of red light on human blood glucose metabolism, it ensures that the illumination light of the light source is soft and does not hurt the eyes.

[0039] Using the lighting source provided in this embodiment for lighting can promote human blood glucose metabolism while lighting, so that the blood sugar control operation can be seamlessly integrated into daily life. Users do not need to invest extra time or energy, reducing the difficulty of blood sugar control. And improving blood glucose metabolism through lighting helps reduce the dependence on drugs and reduce the risk of drug side effects.
