Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to a lighting strip and a lighting system for improving physical and mental health by influencing non-visual pathways. Background Art

[0002] The design and development of existing indoor lighting are all based on the perspective of obtaining visual information from rods and cones in the human eye, that is, by stimulating the visual pathway of the human eye, people can see light. However, the 2017 Nobel Prize in Medicine announced that the "circadian rhythm factor" is controlled by the "non-visual pathway (ipRGCs)". This discovery reveals that the human eye mainly manages endocrine and health through the third type of photoreceptor cells of non-information vision. In layman's terms, "there is no healthy light, only a healthy light environment."

[0003] There are two types of light we come into contact with in daily life: natural light and indoor light.

[0004] 1. Natural light environment:

[0005] The natural daytime is usually a high-brightness, low-stimulation, and uniform illumination environment. The New York Times article "The Sun / s the Best Optometrist" describes: The light intensity of outdoor sunlight is dozens or even hundreds of times higher than that of indoor light. High-intensity light shrinks the pupil, deepens the depth of field, improves image clarity, and inhibits the occurrence of myopia. In addition, the clear sky in nature can generally provide tens of thousands of lux of vertical illumination, and the horizontal illumination is 1 / 3 to 1 / 5 of the vertical illumination. In such a light environment, the endocrine system of a person can function healthily. When engaging in outdoor activities and being exposed to the sun, the dynamic light environment and scenery also allow the eyes to rest and relax.

[0006] Some studies also believe that the reason why sunlight can protect healthy vision is that light can stimulate the release of the neurotransmitter dopamine in the retina. Animal model studies have shown that the retinal dopamine level of myopia is lower than that of normal vision. Therefore, dopamine neurons and their receptors in the retina participate in the signal transmission and regulation of the visual system, and play an important regulatory role in visual development, signal transduction, and refractive development.

[0007] In summary, the natural light environment can provide a high-brightness, low-irritation and uniform light-emitting surface, and provide a high degree of scattering through the atmosphere, so that the illumination is uniform in the entire field of view. Even at the smallest pupil, it can still meet the healthy operation of the visual and non-visual pathways, and play an important role in regulating the physiological and mental health of the human body.

[0008] 2. Indoor Light

[0009] The number of visual photoreceptor cells is tens to hundreds of times that of non-visual pathway photoreceptor cells. Non-visual pathway photoreceptor cells are not of only one type. For example, melatonin, biological clock, pupil size, physiological rhythm, etc. are all managed by different non-visual photoreceptor cells. The convex lens plus pinhole imaging structure of the human eye can project the full-view light environment into the eye. Existing lighting technology is designed based on the angles of obtaining visual information from rods and cones in the human eye. It focuses on visual information and does not focus on the photoreceptor cells that govern physiological rules described in healthy optics. Therefore, the design is made only in consideration of the particle nature of light, and is not designed based on the actual characteristics of quantum optics that project the full-view light environment onto the retina through pinhole imaging of the human eye pupil.

[0010] In traditional lighting methods, the brightness of the light environment can generally satisfy the collection of visual information through pupil dilation, but the enlarged pupil itself means that the light environment is not good, which will activate the corresponding endocrine mechanism. Long-term exposure to such a light environment has unhealthy effects on physiology and psychology. When the pupil becomes smaller, the amount of near light will also decrease, so a higher illumination is required, but the traditional lighting method is uneven and can stimulate when it is high, making the visual pathway and non-visual pathway unable to operate normally.

[0011] For example: (1) The pupil of an average person will become smallest at 3000LX, so many high-speed tunnel entrances usually require the entrance lighting to reach 2000-3000LX or above to prevent the light outside the tunnel from being very strong. When entering the tunnel suddenly, the pupil of the human eye will dilate slowly, and insufficient light intake will cause blindness and danger; (2) In daily movies and TV shows, when interrogating prisoners, a headlight is usually used to illuminate the interrogator. The principle is to cause the visual pathway and non-visual pathway to conflict, leading to endocrine disorders and causing physiological and psychological discomfort. On the contrary, if the scene is moved to the outdoor clear sky, because the surrounding light is uniform and bright, the headlight of the same brightness will lose its stimulating function. On the contrary, because the overall light environment is uniform, bright and low-stimulating, the endocrine system will adjust people in the direction of health and comfort, producing a counterproductive effect.

[0012] Therefore, what can affect the visual information of the human eye is the ambient light in the entire field of view, rather than the brightness of a certain lamp or a certain area.

[0013] However, although high-brightness, low-irritation and uniform lighting can be easily obtained in nature, it is difficult to achieve in indoor environments. The illumination in nature is tens of thousands to hundreds of thousands of lux, but the indoor illumination is only tens to hundreds of lux, which cannot trigger a healthy and reasonable endocrine mechanism. The human eye forms an image through the pinhole of the pupil. Affected by the wave-particle duality of quantum optics, traditional spotlights, table lamps, ceiling lamps, etc. cannot simulate the light with uniform illumination that is scattered by the atmosphere in nature. Therefore, the brightness of fundus imaging will be uneven, causing a disorder in the non-visual pathway that manages endocrine health. In addition, long-term close-range viewing work can easily cause visual fatigue, leading to hyperopic defocusing of the retinal periphery. In the long run, the axial length of the eye will be extended to form myopia.

[0014] In summary, current lighting technology cannot create a high-brightness, low-irritation, and uniformly illuminated light environment similar to that in nature, and thus cannot meet the health needs of non-visual pathways. Utility Model Content

[0015] In order to solve the above deficiencies in the prior art, the utility model aims to provide a lighting strip and a lighting system that improve physical and mental health by affecting non-visual pathways, so as to create a high-brightness, low-irritation and uniform illumination light environment, adapt to the characteristics of non-visual photoreceptor cells in the human eye that are responsible for endocrine secretion, and meet the health needs of non-visual pathways.

[0016] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0017] A lighting strip that improves physical and mental health by affecting non-visual pathways, including a plurality of lighting units connected to each other, each lighting unit including an LED lamp, and a shell with conductive, thermal and heat dissipation functions, the shell including an inner shell with a thermal conductivity function, and an outer shell with a heat dissipation function; the heat dissipation part of the LED lamp is connected to the inner shell, and the luminous flux of the lighting strip is at least 10,000 lumens.

[0020] As a further limitation of the present invention: the LED lamp is a thermoelectric integrated LED, comprising two electrode contacts;

[0021] The top and bottom of the inner and outer shells are both open;

[0022] The inner shell includes two electrode sheets separated from each other, and two electrode contacts of the thermoelectric integrated LED are respectively connected to the two electrode sheets;

[0023] A slot for inserting two electrode sheets of the inner shell is provided between the inner wall and the outer wall of the outer shell, and the size of the slot matches the size of the inner shell; the outer wall of the inner shell is fixed to the outer shell by an adhesive;

[0024] The outer shell is also provided with an LED power connection hole for connecting the two electrode sheets of the inner shell to a power source.

[0025] As a further limitation of the present invention: the surface area of ​​the outer shell is at least three times the surface area of ​​the inner shell.

[0026] As a further limitation of the utility model: the two electrode sheets on the inner shell are respectively connected with connecting sheets, and the connecting sheets are made of pure copper; the two electrode contacts of the thermoelectric integrated LED are respectively fixed on the two connecting sheets, and are connected to the inner shell through the connecting sheets.

[0027] As a further limitation of the present invention: the LED lamp is a thermoelectric separation LED, comprising a heat conducting block and an electrode contact;

[0028] The cross section of the inner shell is circular, and its top surface is a closed surface; a through hole whose size matches the outer diameter of the inner shell is provided in the middle of the outer shell, and the inner shell is sleeved in the through hole of the outer shell;

[0029] The outer wall of the inner shell is fixedly connected to the outer shell by an adhesive, and the heat-conducting block of the thermoelectric separation type LED is fixed on the closed surface of the inner shell;

[0030] The outer shell is also provided with a power-through hole matched with the electrode contact of the thermoelectric separation type LED.

[0031] As a further definition of the utility model: the inner shell includes a cylindrical section and a conical section, the top surface of the cylindrical section is a closed surface; the cylindrical section of the inner shell passes through the through hole, and the outer wall of the cylindrical section is fixedly connected to the outer shell by an adhesive.

[0032] The utility model also provides a lighting system for improving physical and mental health by influencing non-visual pathways: comprising a lighting strip for improving physical and mental health by influencing non-visual pathways as described in any one of claims 1-8, the lighting strip being suspended on the roof through a support, and after being suspended, the light source emitted by the LED lamp is vertically directed toward the roof, forming a light spot at the center of the roof.

[0033] As a further limitation of the present utility model: there are two lighting strips, which are respectively suspended on the roof through supporting members, and two light spots formed by the two lighting strips on the roof do not overlap each other.

[0034] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0035] (1) The utility model includes a lighting strip formed by connecting a plurality of lighting units, each lighting unit includes an LED lamp for providing a light source, and a housing for dissipating the heat generated by the LED lamp; the housing includes an inner housing with electrical and thermal conductivity functions, and an outer housing with a heat dissipation function. There are two types of structures of the inner and outer housings:

[0036] 1. Both the inner and outer shells are cubic structures. The inner shell is inserted into the slot of the outer shell, and then the inner shell and the outer shell are fixed with adhesive. The LED lamp is fixed on the connecting piece of the inner shell. When the LED is working, it will generate heat, and the heat will be transferred to the bottom of the outer shell coated with anodized layer through the pure copper inner shell. The air at the bottom of the outer shell will be heated. According to the principle that hot air will automatically rise, the radiator will form a "chimney effect", generate high-speed hot air flow, and increase the heat dissipation performance;

[0037] 2. The inner shell is a hollow structure, including a cylindrical section and a conical section, and the top surface of the cylindrical section is a closed surface; a through hole with a size that matches the outer diameter of the cylindrical section of the inner shell is set in the middle of the outer shell, and the cylindrical section is fixed to the outer shell through an adhesive after passing through the through hole; the LED is a thermoelectric separation LED, and its heat conduction block is fixed on the closed surface. The heat generated by the LED after working will be transferred to the inner shell through the heat conduction block, and the air inside the inner shell will be accelerated to expand and then ejected from the bottom, and then a negative pressure will be formed inside, which will absorb the external cold air into the interior, and then eject the hot air. As long as there is a heat source, work will be repeated, and the greater the heat, the faster the work will be done, which will accelerate the heat dissipation and play an active heat dissipation effect.

[0038] The above-mentioned lighting strip realizes a light source with sufficient illumination through LED lamps, but a light source with strong illumination has a large amount of heat dissipation, so the heat dissipation effect is ensured by the inner shell and the outer shell, thereby increasing the service life of the lighting strip.

[0039] (2) The utility model also includes a lighting system, including a lighting strip formed by connecting a plurality of lighting units. The lighting strip is suspended on the roof through a support. The structure of the support and the lighting strip allows the light source emitted by the LED lamp to shine vertically toward the roof, forming a light spot at the center of the roof. The light spot can use the white or light-colored roof to scatter light to all corners of the room. According to on-site testing, when each light strip releases 10,000 lumens, the average ground illumination will reach 1500LX. Compared with traditional lighting with an illumination of several hundred lux and uneven illumination, high brightness is initially achieved. The light source is reflected by the roof, simulating the scattering of light by the natural atmosphere, achieving a low-irritation and uniform effect, which basically meets the relaxation and easy visual observation requirements of the human eye;

[0040] If you want to achieve the smallest pupil observation in sunny weather outdoors without causing irritation, you need to extend the light strip to more than 2 meters. The luminous flux of a single light strip needs to be 20000LX. The area of ​​the light spots of the two light strips should exceed 12m without overlapping. 2 In this way, the human eye can have 3000LX illumination, and the surrounding objects also have sufficient illumination to reflect light to the human eye, achieving high brightness and low stimulation in the whole field of vision; in addition, the size of the light strip is 12mm×10mm×1000mm. This structure can ensure that the light reflected downward through the roof is not blocked, and can also ensure the heat dissipation effect.

[0041] In summary, the utility model can create a high-brightness, low-irritation and uniform illumination light environment, adapt to the characteristics of non-visual photoreceptor cells in charge of endocrine in the human eye, and meet the health needs of non-visual pathways; the utility model is suitable for the lighting industry and is used for indoor lighting.

DETAILED DESCRIPTION

[0051] The preferred embodiment of the utility model is described below in conjunction with the accompanying drawings. It should be understood that the lighting strip and lighting system described herein for improving physical and mental health by affecting non-visual pathways are preferred embodiments, which are only used to illustrate and explain the utility model and do not constitute a limitation of the utility model.

[0052] The directional terms or positional relationships such as "up", "down", "left" and "right" described in the embodiments are based on the directional relationships in the drawings in the specification of the utility model and are only for the convenience of describing the utility model and simplifying the description. They do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the content protected by the utility model.

[0053] Example 1 Light strips that improve physical and mental health by affecting non-visual pathways

[0054] The "upper" and "lower" in this embodiment are based on the drawings in the utility model specification. Figure 1 The orientation relationship in Figure 1-2 As shown, this embodiment includes a plurality of lighting units connected to each other. Figure 1 The figure shows a single lighting unit, each of which includes an LED lamp and a shell with electrical, thermal and heat dissipation functions. The shell includes an inner shell with thermal conductivity and an outer shell with heat dissipation function. The heat dissipation part of the LED lamp is fixed to the inner shell, and the luminous flux of the lighting strip is at least 10,000 lumens. To create a high-brightness, low-irritation and uniform illumination light environment, adapt to the characteristics of non-visual photoreceptor cells in charge of endocrine in the human eye, and meet the health needs of non-visual pathways. In this embodiment, the LED lamp is a thermoelectric integrated LED1, and the luminous flux of the lighting strip is 10,000 lumens.

[0055] The following is an example of a single lighting unit:

[0056] like Figure 1As shown, in this embodiment, the shell includes an inner shell 2 with conductive and thermal conductive functions, and also includes an outer shell 3 with a heat dissipation function. Both the inner and outer shells are hollow cubic structures, wherein the top and bottom of the inner shell 2 are open, the thickness of the inner shell 2 is 0.2 mm, and the inner shell 2 includes two electrode sheets that are not connected to each other; a slot 13 is provided between the inner wall and the outer wall of the outer shell 3 for facilitating the insertion of the two electrode sheets of the inner shell 2, the slot 13 passes through the upper surface of the outer shell 3, and the size of the slot 13 is adapted to the size of the inner shell 2. Adaptation here means that the thickness of the slot 13 is slightly larger than the thickness of the inner shell 2, so that the inner shell 2 can be inserted into the slot 13, and the two electrode sheets of the inner shell are inserted from top to bottom into the slot 13 of the outer shell 3 during manufacturing; the surface area of ​​the outer shell 3 is 3 times the surface area of ​​the inner shell 2, and the heat generated by the thermoelectric integrated LED 1 can be evenly transferred to the outer shell 3 with a heat dissipation function; the outer wall of the inner shell 2 is coated with an adhesive 4 to achieve fixation with the outer shell 3.

[0057] The inner shell 2 is made of pure copper and has electrical and thermal conductivity. A connecting piece 6 is provided on the inner shell 2, and the connecting piece 6 includes a first connecting end 61 and a second connecting end 62. The first connecting end 61 and the second connecting end 62 are respectively connected to two electrode pieces, and the first connecting end 61 and the second connecting end 62 are not in contact with each other. The thermoelectric integrated LED 1 is welded on the connecting piece 6, and the two electrode contacts of the thermoelectric integrated LED 1 are respectively connected to the first connecting end 61 and the second connecting end 62. In this embodiment, the thermoelectric integrated LED 1 uses 2835 LED. Since the thermoelectric integrated LED 1 is a prior art, it will not be elaborated in detail here. The connecting piece 6 is made of pure copper and has excellent electrical conductivity and heat transfer properties.

[0058] The outer shell 3 is made of aluminum, and its surface is an anodized layer 7, and the film thickness of the anodized layer 7 is above 50μm; the outer shell 3 is also provided with an LED power connection hole 5, which is a groove opened on the surface of the outer shell 3. It should be noted that the groove only penetrates the outer wall of the outer shell 3, that is, it is only opened to the slot 13, so that the power line is in contact with the inner shell 2, and the inner shell 2 corresponding to the LED power connection hole 5 is not coated with adhesive 4. The external power source contacts the inner shell 2 through the groove to supply power to the thermoelectric integrated LED 1. The power supply method of the thermoelectric integrated LED 1 is a prior art and will not be elaborated in detail here.

[0059] It should be noted that, if you want to increase the heat dissipation efficiency, you can set the thickness of the inner shell 2 to be greater than 0.2 mm, or increase the size of the outer shell 3. In this embodiment, the inner shell 2 and the outer shell 3 are not limited to cubic structures, but can also be cylindrical or other structures.

[0060] The adhesive 4 in this embodiment is a self-heating adhesive, and its preparation method is as follows:

[0061] Weigh 10 parts of water and add it to a polytetrafluoroethylene container, heat it, add 3 parts of polyvinyl alcohol, and stir continuously. At the same time, raise the reaction temperature to 90-95°C until the polyvinyl alcohol is completely dissolved, cool it to 65-70°C, gradually add 1 part of phosphoric acid, additives, adjust the pH value to 2.0-2.5 with hydrochloric acid, heat it to 85-90°C, react for a certain time, and when the viscosity of the glue does not increase significantly, add 1 part of formaldehyde dropwise, react at a constant temperature for a certain time, cool it to 60°C, add sodium hydroxide to adjust the pH value to 6.2-8.0, add urea, add plasticizer after reacting for a certain time, cool it to below 40°C, add 3 parts of polysiloxane and 6 parts of hexagonal boron nitride, stir it fully, and discharge it after stirring evenly.

[0062] When in use, the self-heat-conducting adhesive is evenly applied to the pure copper inner shell 2, with a minimum thickness of 0.015 mm and a maximum thickness of 0.1 mm. This size can not only play a bonding role, but also achieve good heat conduction and insulation effects. Then the pure copper inner shell 2 is placed in the outer shell 3 and baked at 150 degrees for more than 3 hours. The adhesive 4 in this embodiment can also be selected from other types of adhesives with strong bonding force, strong heat resistance and insulation effect, such as epoxy AB glue.

[0063] When using this embodiment, if Figure 2 As shown, the lighting strip includes several lighting units. In this embodiment, the shells of several lighting units are integrally cast into a long strip structure, and two adjacent lighting units can also be connected by bonding with an adhesive 4. When the thermoelectric integrated LED 1 is powered on, it will generate heat, and the heat will be transferred to the bottom of the outer shell 3 with an anodized layer 7 through the inner shell 2 of pure copper. The air around the bottom will be heated. According to the principle that hot air will automatically go upward, the shell will form a "chimney effect", generate high-speed hot air flow, and increase the heat dissipation performance, which is similar to a self-aspirated radiator. In addition, the heat dissipation performance can be guaranteed by increasing the thickness of pure copper and increasing the size of the outer shell 3 to achieve thermoelectric integration. This structure realizes a light source with sufficient illumination through the LED lights on the lighting strip, but the light source with strong illumination has a large amount of heat dissipation, so the heat dissipation effect is guaranteed through the inner shell and the outer shell, thereby increasing the service life of the lighting strip.

[0064] Example 2 Light strips that improve physical and mental health by affecting non-visual pathways

[0065] The “upper”, “lower”, “left” and “right” in this embodiment are based on the drawings of the utility model specification. Figure 3 In this embodiment, the LED lamp is a thermoelectric separation type LED 17, including a heat conducting block 18 and an electrode contact 19.

[0066] like Figure 3 to Figure 5As shown, in this embodiment, the shell includes an inner shell 2 with electrical and thermal conductivity functions, and also includes an outer shell 3 with heat dissipation function. The difference between this embodiment and embodiment 1 is that the inner shell 2 is a hollow structure, wherein the upper half is a cylindrical section 8, the lower half is a conical section 9, the top surface of the cylindrical section 8 is a closed surface 81, the material of the inner shell 2 is pure copper, which has excellent electrical conductivity and heat transfer performance, and the thickness of the inner shell 2 is 0.2mm;

[0067] The outer shell 3 is made of aluminum, has a heat dissipation function, and is a cubic structure as a whole. A through hole 10 is provided in the middle of the outer shell 3, and the size is adapted to the outer diameter of the cylindrical section 8 of the inner shell 2. Adaptation here means that the inner diameter of the through hole 10 is equal to the outer diameter of the cylindrical section 8; the outer wall of the cylindrical section 8 is coated with adhesive 4, and after the cylindrical section 8 passes through the through hole 10, it is fixed to the outer shell 3 by adhesive 4, and the adhesive 4 here is the same as the adhesive 4 in Example 1; the heat conducting block 18 of the thermoelectric separation LED 17 is welded and fixed to the closed surface 81 of the inner shell 2. In this embodiment, the thermoelectric separation LED 17 uses 5730LED. Since the thermoelectric separation LED 17 is a prior art, it will not be elaborated here;

[0068] The outer shell 3 is also provided with a first power-through hole 11 and a second power-through hole 12 that match the two electrode contacts 19 of the thermoelectric separation LED 17. The power line passes through the first power-through hole 11 and the second power-through hole 12 and contacts the two electrode contacts 19 for power supply. The surface of the outer shell 3 is an anodized layer 7, and the film thickness of the anodized layer 7 is above 50 μm. It should be noted that if you want to increase the heat dissipation efficiency, you can set the thickness of the inner shell 2 to be greater than 0.2 mm, or increase the size of the outer shell 3.

[0069] The other structures are exactly the same as those in Example 1 and will not be described in detail in this example.

[0070] When using this embodiment, if Figure 5 As shown, the outer shells of several lighting units are integrally cast into a long strip structure. When the thermoelectric separation LED 17 is powered on and generates heat, the air inside the inner shell 2 will accelerate the expansion and then spray out from the bottom. After that, a negative pressure is formed inside the inner shell 2, which will absorb the external cold air into the internal heat dissipation, and then spray out, similar to a pulsed self-breathing radiator. As long as there is a heat source, work will be repeated, and the greater the heat, the faster the work is done, which accelerates the heat dissipation and realizes thermoelectric integration. This structure realizes a light source with sufficient illumination through the LED lights on the lighting strip, but the light source with strong illumination has a large amount of heat dissipation, so the heat dissipation effect is guaranteed by the inner shell and the outer shell, thereby increasing the service life of the lighting strip.

[0071] Example 3: Lighting system that improves physical and mental health by affecting non-visual pathways

[0072] like Figure 6 , Figure 7 As shown, in this embodiment, the lighting strip is hung on the roof 14 through the support 16. The support 16 in this embodiment can be a carbon fiber rod, or an iron rod or other material, as long as the lighting strip can be hung firmly on the roof. And because the overall weight of the lighting strip is relatively light, only a few hundred grams, the support 16 can firmly hang the lighting strip on the roof 14. This embodiment takes the lighting strip of Example 1 as an example, and explains it with a daily family room of 2.7m high, 5m long, and 3m wide:

[0073] There are two lighting strips, the size of which is 12mm×10mm×1000mm, and the length of each light strip is 1m. The two lighting strips are hung at a distance of 60cm from the roof 14. The outer shell 3 and the connecting piece 6 form a certain angle to ensure that the light source emitted by the thermoelectric integrated LED 1 welded on the connecting piece 6 is vertically irradiated to the roof 14 and forms a light spot 15 on the roof 14. The area of ​​each light spot 15 is 4m 2 , two light spots 15 or 8m 2 , and the two light spots 15 do not overlap each other; the light spot 15 can use the white or light-colored roof 14 to scatter light to all corners of the room. This size can ensure that the light reflected downward from the roof 14 is not blocked, and the heat dissipation effect is guaranteed. It should be noted that in order to increase the heat dissipation effect, the thickness of the inner shell 2 can be set to be greater than 0.2mm, or the size of the outer shell 3 can be increased, and it is only necessary to ensure that the outer shell 3 does not block the light reflected downward from the roof 14; this ensures that the volatility of light can be brought into play, and does not hinder too much illumination, so that the light can be reflected from the roof 14 to achieve high brightness, low stimulation and uniformity.

[0074] After field testing, when each light strip releases 10000lm, the average ground illumination will reach 1500LX. It should be noted that lux is the unit of illumination, and lumen is the unit of luminous flux. 1 lux = 1 lumen / square meter, that is, 1LX = 1lm / m 2 The value calculated by this formula has a slight deviation from the actual on-site measurement, and the actual ground illuminance tested shall prevail. Compared with the traditional lighting with an illuminance of several hundred lux and uneven illuminance, this structure has initially achieved a high-brightness effect, and the light source is reflected back to the ground through the roof 14, simulating the scattering of light by the natural atmosphere, achieving a low-irritation and uniform effect, which basically meets the relaxation and easy visual observation of the human eye.

[0075] If you want to achieve the smallest pupil observation in sunny weather outdoors without causing irritation, you need to extend the light strip to more than 2 meters. The luminous flux of a single light strip needs to be 20000LX. The spot of 15 of two light strips should be more than 12m without overlapping. 2In this way, the human eye can have 3000LX illumination, and the surrounding objects also have sufficient illumination to reflect light to the human eye, achieving high brightness and low stimulation in the whole field of view.

[0076] This lighting system can create a high-brightness, low-stimulation and uniform illumination light environment. For example, 90% of indoor roofs on the market are matte white or light-colored. This lighting method can achieve a vertical illumination of 70% of the area in the house that is 3 to 5 times the horizontal illumination, which is similar to natural light. The main purpose of the human eye is to obtain information, of which visual information is handled by the visual pathway, and non-visual information is mainly managed through the light environment to manage endocrine. Both mechanisms are very sensitive to the stimulation caused by the difference between light and dark, which is equivalent to noise in information theory. It will cause the existing information to be processed incorrectly, and is also the main reason for various physiological and psychological diseases caused by long-term use of traditional indoor lighting. Let the ambient light adapt to the characteristics of the non-visual photoreceptor cells in the human eye that are responsible for endocrine, treat some eye diseases, improve physiological rhythms, emotions, cognitive functions, prevent and treat neurological diseases such as Alzheimer's disease, and meet the health needs of non-visual pathways.

[0077] This embodiment can also use the lighting strip of embodiment 2, and its hanging method is the same as this, that is, the light source is allowed to vertically illuminate the roof 14, and realize indoor lighting after reflection, which will not be described in detail here.
