[0002] With the advancement of technology and the improvement of living standards, various lighting tools have emerged in the consumer market. As the main lighting tool, lamps usually use LED light sources. However, as people's quality of life improves, the pursuit of LED light sources is no longer simply about high luminous efficiency to meet basic lighting needs. Instead, the focus is more on the impact on human health, visual experience, and work efficiency.

[0003] From the perspective of human health, some light tubes on the market are beneficial to users' health, such as the Chinese utility model patent "A Multifunctional Light Health Light Tube" (CN212657594U). From the perspective of visual experience, there are many uniquely designed lighting tools. Due to the large number of existing technologies in this area, no examples will be given here. However, from the perspective of work efficiency, most existing lighting tools are designed to increase the intensity of light during work, making the light clearer and brighter, thereby improving work efficiency. However, working under excessively intense light for a long time can affect eye health. Summary of the Invention

The light emitted by the light source is light in the 360-800nm ​​band, and the light in the 360-800nm ​​band is divided into N bands, each of which has a different percentage of spectral radiation energy.

[0006] Furthermore, the color temperature range of the light emitted by the light source is 4000K-5300K.

[0007] Furthermore, in the light emitted by the light source, the spectrum of the N bands includes 360-400nm, 400-420nm, 420-453nm, 453-490nm, 490-540nm, 540-580nm, 580-636nm, 636-700nm and 700-800nm.

[0008] Furthermore, in the light emitted by the light source, the percentage of spectral radiant energy in the 360-400nm band is 0.01%-1.00%, in the 400-420nm band it is 0.04%-0.06%, in the 420-453nm band it is 4.21%-6.32%, in the 453-490nm band it is 12.24%-18.36%, and in the 490-540nm band... The percentage of spectral radiant energy is 15.91%-23.87% in the 540-580nm band, 10.00%-15.00% in the 580-636nm band, 16.13%-24.19% in the 636-700nm band, 16.25%-24.38% in the 700-800nm ​​band, and 5.21%-7.81% in the 700-800nm ​​band.

[0011] The beneficial effects of the light source for improving work efficiency described in this invention are as follows: Through the experiment in specific embodiment 4, the correlation between the spectrum of the light emitted by the light source of this invention and the melanopsin curve was verified, thus proving that the light source of this invention can reduce the drowsiness of users when studying and working, thereby playing a role in improving work efficiency. Since the design concept is to improve the correlation coefficient with the melanopsin curve by combining various spectral bands, unlike existing light sources that improve work efficiency by increasing the intensity of illumination during work to make the light clearer and brighter, the light source of this invention can improve work efficiency in strict accordance with national standards, and therefore will not harm the user's eye health.

Detailed Implementation

[0013] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0014] Example 1 This embodiment provides a light source for assisting in improving work efficiency. The light source emits light that enhances work efficiency, with a wavelength range of 360-800nm. This 360-800nm ​​wavelength range is further divided into N bands, each with a different percentage of spectral radiant energy. The color temperature range of the emitted light is 4000K-5300K, and the illuminance of the emitted light conforms to national standards.

[0015] The N spectral bands include 360-400nm, 400-420nm, 420-453nm, 453-490nm, 490-540nm, 540-580nm, 580-636nm, 636-700nm, and 700-800nm.

[0016] In the light emitted by the light source, the percentage of spectral radiant energy in the 360-400nm band is 0.01%-1.00%, in the 400-420nm band it is 0.04%-0.06%, in the 420-453nm band it is 4.21%-6.32%, in the 453-490nm band it is 12.24%-18.36%, and in the 490-540nm band it is [missing information]. The percentages are 15.91%-23.87%, the percentage of spectral radiation energy in the 540-580nm band is 10.00%-15.00%, the percentage of spectral radiation energy in the 580-636nm band is 16.13%-24.19%, the percentage of spectral radiation energy in the 636-700nm band is 16.25%-24.38%, and the percentage of spectral radiation energy in the 700-800nm ​​band is 5.21%-7.81%, as shown in Table 1.

[0017] Table 1:

[0018] Example 2 This embodiment further defines Embodiment 1, providing an energy distribution of light emitted by a light source that satisfies the limitations of Embodiment 1, as shown in Table 2: Table 2:

[0019] Example 3 This invention further defines the embodiments. The light source described in Embodiment 1 can be used for spectral synthesis in the following manner: Figure 1 The continuous spectrum curve of the light emitted by the light source described in Example 1 is given. Based on this curve, spectral synthesis can be performed in the following manner: Option 1: Light can be emitted by using one or more light-emitting chips of specific wavelengths to excite phosphors, emitting light that conforms to the scheme defined in Example 1, thereby forming the light source described in Example 1 of this invention.

[0020] Option 2: Light that conforms to the scheme defined in Example 1 can be emitted by arranging and combining one or more light-emitting chips of specific wavelengths, thereby forming the light source described in Example 1 of the present invention.

[0021] Option 3: The light source described in Example 1 of this invention can be formed by using one or more light-emitting chips of specific wavelengths to excite a light source encapsulated in a quantum dot powder mixture, or by using a thin film made of quantum dots to emit light that conforms to the scheme defined in Example 1.

[0022] Option 4: The light source described in Embodiment 1 of the present invention can be formed by using one or more light-emitting chips of specific wavelengths to excite the organic light-emitting material itself or the thin film made therefrom to emit light that conforms to the above-mentioned continuous spectrum and radiance.

[0023] Among them, the amount of organic light-emitting materials depends on the accuracy of the simulated spectral curve, and the combination of different types of light-emitting chips, phosphors, and quantum dots.

[0024] Example 4 This embodiment further defines Embodiment 1 and further illustrates how the relationship between the spectrum and the melanopsin curve shows that the light source in Embodiment 1 can reduce drowsiness for users when studying and working, thereby helping to improve work efficiency.

[0025] The specific experimental method is as follows: The nm band with the highest content in the experimental spectrum is considered as 1. The entire spectral parameter is normalized. The percentage of each nm band in the total spectral content is calculated. This percentage is multiplied by the value of each nm band in the melanopsin curve. The resulting data is the correlation coefficient between the experimental spectrum and each nm band of the melanopsin curve. All correlation coefficients are summed to obtain the total correlation parameter. Based on the correlation parameter, the influence of all spectra, including the experimental spectrum, on the melanopsin curve can be evaluated, i.e., its influence on melatonin secretion levels. A higher correlation parameter value indicates a stronger ability to inhibit melatonin, while a lower correlation parameter value indicates a weaker ability to inhibit melatonin.

[0026] The spectrum in Example 1 is used as experimental spectrum 1, and the spectrum of a commercially available read / write lamp is used as experimental spectrum 2. Through the above experiments, the total correlation parameter of experimental spectrum 1 is 0.331 and the total correlation parameter of experimental spectrum 2 is 0.294.

[0027] Experimental comparison shows that the total correlation parameter of experimental spectrum 1 provided by this invention is 11.12% higher than that of experimental spectrum 2. Therefore, it can be proven that it has a stronger ability to inhibit melatonin and can help improve work and study efficiency.

The device includes a light-emitting module, which is composed of several light sources as described in Embodiment 1. The arrangement and combination of the light sources in the light-emitting module can be customized according to specific design and actual needs. The combination method is not limited here; only a schematic diagram of the combination method is provided, such as... Figure 2 (a) and (b) in the text give two different combinations.

[0029] Example 6 This embodiment provides a lamp to help improve work efficiency. The lamp includes conventional lamp structures such as a housing and a substrate. A light source device to help improve work efficiency is installed in the lamp as its light source. People who need to improve their work or study efficiency can use this lamp to help improve their work or study efficiency.
