Description

Technical Field

[0001] This application relates to the field of lighting source technology, and in particular to a lighting source. Background Technology

[0002] With the rapid development of lighting technology, lighting sources have undergone multiple iterations and updates, from the first generation of lighting sources that only pursued brightness and illuminance to the second generation that pursued high luminous efficiency and energy saving, then to the third generation that pursued light quality, and then to the fourth generation that pursued low blue light and spectral modulation that mimicked sunlight. These multiple iterations and updates are based on people's pursuit of different functions of lighting sources.

It is understood that the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0027] This application provides a lighting source that can reduce blue light hazards, regulate circadian rhythms, improve night vision illumination, provide photopic illumination, and provide health restoration functions. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of an embodiment of the lighting source of this application. Figure 5 This is a schematic diagram of the light power distribution of the lighting source in this application. (See diagram for example.) Figure 4 As shown, the lighting source 10 in this embodiment includes a plurality of light-emitting elements 11.

[0028] Among them, multiple light emitters 11 are used to generate an output spectrum with five output peaks, and the overall output spectrum of the illumination source 10 is as follows: Figure 5 As shown, it includes a first output peak with a peak wavelength between 390nm and 445nm, a second output peak with a peak wavelength between 445nm and 490nm, a third output peak with a peak wavelength between 490nm and 540nm, a fourth output peak with a peak wavelength between 540nm and 620nm, and a fifth output peak with a peak wavelength between 620nm and 690nm.

[0029] Specifically, in this embodiment, in the output spectrum of the illumination source 10, the light power ratio of the first output peak is between 0.5% and 3%, the light power ratio of the second output peak is between 1% and 15%, the light power ratio of the third output peak is between 5% and 25%, the light power ratio of the fourth output peak is between 20% and 50%, and the light power ratio of the fifth output peak is between 20% and 50%.

[0030] Furthermore, in other embodiments, the optical power ratio of the first output peak may be set to be between 1% and 2.5%, the optical power ratio of the second output peak to be between 5% and 14%, the optical power ratio of the third output peak to be between 8% and 21%, the optical power ratio of the fourth output peak to be between 22% and 40%, and the optical power ratio of the fifth output peak to be between 23% and 48%.

[0031] Furthermore, in other embodiments, the optical power ratio of the first output peak may be set to be between 1.2% and 2.0%, the optical power ratio of the second output peak to be between 10% and 13%, the optical power ratio of the third output peak to be between 10% and 20%, the optical power ratio of the fourth output peak to be between 25% and 37%, and the optical power ratio of the fifth output peak to be between 28% and 45%.

[0032] Optionally, output peaks with different light power ratios can be superimposed to output light of different colors. Therefore, this application adjusts the light power ratios corresponding to the first, second, third, fourth, and fifth output peaks to adjust the color of the light output by the lighting source 10, thereby achieving the corresponding chromaticity requirements. It has the advantage of high applicability and can be widely used in various lighting environments.

[0033] Meanwhile, as can be seen from the above different embodiments, the light power ratio of the fourth output peak of the lighting source 10 of this application is between 20-50%, and it is used to improve the illuminance of light. It can be seen that the lighting source 10 of this application is mainly used to meet the lighting needs when the ambient illuminance is relatively high, such as reading and writing desk lamp lighting when the main indoor lighting fixture is turned on during the day or at night.

[0034] Furthermore, the lighting source 10 of this application can be configured with the peak wavelength of the first output peak being between 390nm and 445nm, the peak wavelength of the second output peak being between 470nm and 490nm, the peak wavelength of the third output peak being between 495nm and 515nm, the peak wavelength of the fourth output peak being between 540nm and 560nm, and the peak wavelength of the fifth output peak being between 620nm and 640nm. The five output peaks with the above-mentioned different peak wavelengths illustrate the multiple advantages of the lighting source 10 of this application.

[0035] Specifically, in this embodiment, the x-value of the CIE coordinate (chromaticity coordinate) of the output light from the illumination source 10 is between 0.38 and 0.44, and the y-value is between 0.38 and 0.44; or, the x-value of the CIE coordinate is between 0.30 and 0.38, and the y-value is between 0.30 and 0.38; or, the x-value of the CIE coordinate is between 0.44 and 0.52, and the y-value is between 0.44 and 0.52.

[0036] Combination Figure 4 and Figure 5 For further information Figure 2 , Figure 2 These are the human eye's visual function curve and rhythm response curve. Optionally, in this embodiment, when the illumination distance is between 0.3m and 0.5m, and under the rated power of the illumination source 10, the illuminance of the output light of the illumination source 10 is not less than 700 Lux.

[0037] Luminous flux refers to the radiant power that the human eye can perceive; it is equal to the radiant energy of the lighting source 10 in a certain wavelength band per unit time (specifically...). Figure 5 The product of the curve shown and the relative visibility of that band, i.e., the sum of the radiant energy of a certain band per unit time and... Figure 2 The product of the curves shown. Specifically, the photopic luminous flux is the photopic luminous flux function, i.e., the photopic luminous flux function is taken as the photopic luminous flux function. Figure 2 The curve S13 shown corresponds to the illuminance calculated from the photopic luminous flux.

[0038] Optionally, in this embodiment, when the lighting distance is between 2.5m and 3.5m and the rated power of the lighting source is within the range, the dark visual illuminance of the output light of the lighting source is not less than 500 Lux.

[0039] Wherein, the scotopic luminous flux is the scotopic luminous flux function, which is the scotopic luminous flux function. Figure 2 The curve S11 shown corresponds to the illuminance calculated from the illuminance of the dark vision luminous flux.

[0040] Specifically, the lighting source 10 in this application can be a chandelier or a table lamp placed on a desktop, and further combined with Figure 2 The lighting source 10 in different usage environments is described.

[0041] Optionally, when the user is in a relatively limited space, such as a bedroom, the user can use a desk lamp placed on a desk, i.e., the lighting source 10. In this case, the straight-line distance from the lighting source 10 to the user's eyes can be set to between 0.3m and 0.5m.

[0042] Since the light source 10 is relatively close to the user, the user may use the light source 10 to read books or magazines, thus requiring a certain level of illumination to clearly see text or pictures at close range. Specifically, by Figure 2As can be seen from curve S13, the main peak of the photopic vision function is located between 550nm and 560nm, and the peak wavelength of the fourth output peak of the illumination source 10 of this application is between 540nm and 560nm, and its light power ratio is between 20% and 50%. Therefore, this application improves photopic illuminance through the fourth output peak.

[0043] Optionally, when the user is in a large space, such as an auditorium or a large conference room, the user can use the lighting source 10 of the chandelier, and the distance between the lighting source 10 and the user in the direction of gravity is set to 2.5m-3.5m.

[0044] Because the light source 10 is relatively far from the user, a certain level of low-light illumination is required when the user needs to clearly read the text and images in the book or other text-based tools in their hand. Specifically, by Figure 2 As can be seen from curve S11, the main peak of the photopic vision function is located between 490nm and 510nm, and the peak wavelength of the third output peak of the illumination source 10 of this application is between 495nm and 515nm, and its light power ratio is between 5% and 25%. Therefore, this application improves dark vision illuminance through the third output peak.

[0045] Furthermore, in this embodiment, the EML efficiency of the output light from the illumination source 10 is not less than 0.25. Here, EML efficiency is the EML power ratio per unit of optical power, specifically the radiant energy of a certain wavelength band within the full wavelength range of the illumination source 10 (specifically...). Figure 5 The curve shown) and the EML weighting function for this band (i.e. Figure 2 The sum of the products of the curves S12 shown is divided by the sum of the optical power across the entire wavelength band.

[0046] The lighting source 10 in this application is designed for lighting needs in environments with relatively high illuminance, where the user is awake. Furthermore, research on human circadian rhythms indicates that 490nm blue light can affect melatonin secretion. Figure 2 As can be seen from curve S12, when the wavelength is between 485nm and 495nm, it can meet the design requirements of a high EML light source. Furthermore, the peak wavelength of the second output peak of the lighting source 10 of this application is between 470nm and 490nm, and its light power ratio is between 1% and 15%. Therefore, this application can achieve regulation of biological rhythms through the second output peak.

[0047] Combination Figure 4 and Figure 5 For further information Figure 1 , Figure 1 This is a schematic diagram of the normalized weighted coefficient for blue light hazard. In this embodiment, the blue light hazard efficiency of the output light of the illumination source 10 is no greater than 0.1. Specifically, the radiant energy of a certain wavelength band within the full wavelength range of the illumination source 10 (specifically...) Figure 5 The curve shown) and the weighting function of blue light hazard in this band (i.e. Figure 1 The sum of the products of the curves shown is divided by the sum of the optical power across the entire wavelength band.

[0048] Among them, such as Figure 1 As shown, the blue light hazard weighting function can be divided into safe zone, warning zone, and risk zone according to the wavelength range. The safe zone indicates that the light in the wavelength range has no blue light hazard and will not cause blue light damage to the human eye, and can be used for a long time. The warning zone indicates that the light in the wavelength range has some blue light hazard and the usage time needs to be controlled. The risk zone indicates that the light in the wavelength range has blue light hazard and will cause serious blue light damage to the human eye, and the use of light in the wavelength range needs to be prohibited.

[0049] Specifically, the blue light hazard weighting function can be derived by irradiating animals (such as mice) with light of different wavelengths but the same power, observing the degree of harm caused to the animals to obtain their blue light hazard curves, and further calculating the corresponding curve for the human eye based on the response relationship between the human and animal eyes. This curve is then used to determine the blue light hazard risk. Figure 1 The normalized weighted coefficients for blue light hazards are shown.

[0050] like Figure 1 As shown, the safe zone ranges from less than 405nm to greater than 490nm, and the warning zone ranges from greater than 405nm and less than 415nm to greater than 470nm and less than 490nm. Specifically, the peak wavelength of the first output peak in this application is between 390nm and 445nm, located within the safe zone, and its optical power percentage is between 0.5% and 3%. The peak wavelength of the second output peak is between 470nm and 490nm, located within the warning zone, and its optical power percentage is between 1% and 15%. The emitting element in this application does not generate or emit blue light in the band between the first and second output peaks, and the optical power percentage of the first and second output peaks near the blue light band is small. Furthermore, the first and second output peaks meet the requirements of the normalized weighted coefficient for blue light hazard. Therefore, this application can reduce blue light hazard through the first and second output peaks.

[0051] Combination Figure 4 and Figure 5 For further information Figure 3 , Figure 3 This is a diagram illustrating how the human body absorbs light of different wavelengths, such as... Figure 3 As shown, the relative absorption rates of hemoglobin, oxyhemoglobin, and melanin decrease significantly in the 600nm-1300nm range. The relative absorption rate can be understood as the ratio of the light entering the body minus the emitted and reflected light to the light initially entering the body; that is, the relative absorption rate is the absorbed light power divided by the incident light power.

[0052] Depend on Figure 3 It is known that the 600nm-1300nm wavelength band is the tissue optical window, meaning that most of the light in this band can enter the human eye and play a role in the health repair function of the human eye. Among them, the peak wavelength of the fifth output peak of this application is between 620nm-640nm, and its optical power accounts for 20-50%. Therefore, this application achieves the health repair function through the fifth output peak.

[0053] Specifically, the plurality of light emitters 11 in this embodiment may include, for example: Figure 4 The light emitters 11A, 11B, 11C, 11D, and 11E shown herein have the following characteristics: light emitter 11A outputs a first output peak, light emitter 11B outputs a second output peak, light emitter 11C outputs a third output peak, light emitter 11D outputs a fourth output peak, and light emitter 11E outputs a fifth output peak. This embodiment is merely an example; in other embodiments, different light emitters 11 may output other output peaks.

[0054] The first, second, third, fourth, and fifth output peaks are emitted by an electroluminescent device or a photoluminescent device, respectively. Optionally, the electroluminescent device described in this embodiment can be a light-emitting chip, and the photoluminescent device can be a phosphor or a wavelength conversion structure, etc.

[0055] Optionally, in one embodiment, the first output peak, second output peak, third output peak, fourth output peak, and fifth output peak can all be output by an electroluminescent device, that is, the lighting source 10 includes five light-emitting chips, which are respectively used to output the first output peak, second output peak, third output peak, fourth output peak, and fifth output peak. The five light-emitting chips in this embodiment can greatly improve the illumination brightness of the lighting source 10, that is, it has high luminous efficacy.

[0056] Optionally, in one embodiment, the first output peak is output by an electroluminescent device, and the second, third, fourth, and fifth output peaks are respectively output by a photoluminescent device with the first output peak as the excitation source.

[0057] That is, the first output peak is specifically emitted by the electroluminescent device, i.e., by the light-emitting chip. The second, third, fourth, and fifth output peaks are all emitted by the photoluminescent device, specifically by stimulated emission of phosphors. Specifically, the first output peak serves as the excitation source; different phosphors, upon receiving the first output peak, are stimulated to emit the second, third, fourth, and fifth output peaks, respectively. This embodiment uses stimulated emission of phosphors, which simplifies the process, improves the yield of the lighting source 10, reduces production costs, and also results in higher luminous efficacy for the lighting source 10.

[0058] Optionally, in one embodiment, the first and second output peaks are specifically output by an electroluminescent device, i.e., by a light-emitting chip, while the third, fourth, and fifth output peaks are all emitted by a photoluminescent device, specifically by phosphors being excited and emitted. Specifically, different phosphors receive the first output peak and are excited to emit the third, fourth, and fifth output peaks.

[0059] Optionally, in one embodiment, at least two of the first, second, third, fourth, and fifth output peaks are output by the same light-emitting chip.

[0060] That is, the light-emitting chip can emit corresponding output peaks through dual electroluminescence, or the light-emitting chip can be a light-emitting chip with an electroluminescent layer and a photoluminescent layer. Specifically, the electroluminescent layer outputs one of the first output peak, the second output peak, the third output peak, the fourth output peak, and the fifth output peak, and excites the photoluminescent layer to emit the other of the first output peak, the second output peak, the third output peak, the fourth output peak, and the fifth output peak in a photoluminescent manner.

[0061] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
