[0037] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly explained below. Obviously, the described drawings are only a part of the embodiments of the present invention, and not all of them. Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0038] Figure 1 This is a diagram showing the selection of light sources for lighting devices that enhance the freshness of food. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] It should be noted that although functional modules are divided in the system diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0041] refer to Figure 1 A five-channel light-emitting device is provided, which emits mixed light. The mixed light can provide a better visual freshness for fresh foods in yellow, orange, red and white, green, light and gray tones.

[0042] Objects can be categorized into several color families. For food, common family families include yellow, orange, red and white, green, light, and gray. Yellow refers to food whose overall color leans towards yellow, such as bananas. Red refers to food whose overall color leans towards red, such as beef. Red and white refers to food whose overall color leans towards red and white, such as pork or chicken. Green refers to food whose overall color leans towards green, such as broccoli and other leafy green vegetables. Light colors generally refer to lighter-colored foods, such as steamed buns and other pastries. Gray refers to foods with a certain degree of darkness, such as seafood.

[0043] The light-emitting device of this application emits mixed-color light that can specifically enhance the visual freshness of yellow, orange, red-white, green, light-colored, and gray foods. The mixed light employs a five-channel technique for mixing different colored lights. The five channels output the following colors: Royal Blue, Mint, Cyan, White (4000K), and Red. The White light has a color temperature of 4000K. These five colors are output through the five light channels and mixed to obtain the mixed light.

[0044] For these five colors of light, it can be found from the spectral characteristics of each color that the dominant wavelength, peak wavelength and full width at half maximum (FWHM) of these five colors of light need to be restricted in the spectrum.

[0045] Among them, the main wavelength of the sapphire blue light needs to be in the range of 445nm to 475nm, the peak wavelength of the sapphire blue light needs to be in the range of 440nm to 470nm, and the full width at half maximum (FWHM) of the sapphire blue light needs to be in the range of 15nm to 30nm.

[0046] The dominant wavelength of mint-colored light needs to be in the range of 535nm to 575nm, the peak wavelength of mint-colored light needs to be in the range of 528nm to 568nm, and the full width at half maximum (FWHM) of mint-colored light needs to be in the range of 80nm to 150nm.

[0047] The dominant wavelength of cyan light needs to be within the range of 491nm to 511nm, the peak wavelength of cyan light needs to be within the range of 488nm to 508nm, and the full width at half maximum (FWHM) of cyan light needs to be within the range of 20nm to 60nm.

[0048] The dominant wavelength of white light needs to be within the range of 570nm to 610nm, the peak wavelength of white light needs to be within the range of 600nm to 640nm, and the full width at half maximum (FWHM) of white light needs to be within the range of 150nm to 225nm.

[0049] The dominant wavelength of red light needs to be within the range of 615nm to 640nm, the peak wavelength of red light needs to be within the range of 620nm to 650nm, and the full width at half maximum (FWHM) of red light needs to be within the range of 15nm to 35nm.

[0050] Research has shown that when the dominant wavelength, peak wavelength, and half-peak width of royal blue, mint, cyan, white (4000K), and red light are within a set range, the resulting mixed light contributes to enhancing the visual freshness of fresh foods in yellow, orange, red-white, green, light, and gray tones.

[0051] This invention mixes five colors of light—royal blue, mint, cyan, white (4000K), and red—and limits the dominant wavelength, peak wavelength, and half-peak width of each color to obtain a mixed light that enhances the visual freshness of yellow, orange, red-white, green, light, and gray foods. This addresses the shortcomings of existing lighting technologies that fail to effectively enhance the visual freshness of yellow, orange, red-white, green, light, and gray foods.

[0052] Studies based on the relative spectral power distribution of mixed light obtained from royal blue, mint, cyan, white (4000K), and red light reveal that, in enhancing the visual freshness of yellow and orange foods, the luminous flux of each color needs to fall within a certain range, and the correlated color temperature of the resulting mixed light also needs to be limited.

The sum of the proportions of the five colors is 1.

[0056] For yellow and orange foods, the mixed light scheme used includes a correlated color temperature range of 3400K to 3600K.

The sum of the proportions of the five colors is 1.

[0058] To illustrate more clearly, let 'a' represent the luminous flux of royal blue light; 'b' represent the luminous flux of mint light; 'c' represent the luminous flux of cyan light; 'd' represent the luminous flux of white light (4000K); and 'e' represent the luminous flux of red light.
