Referring to fig. 5, the normalized spectrum of white light satisfies the condition:
the normalized spectrogram comprises a first red light wave band, and the half-wave width of the first red light wave band is 15 nm-30 nm. Specifically, the half-wave width of the first red light band may be selected from 15nm, 18nm, 24nm, 27nm, 30nm, and the like, wherein 30nm is preferred, and the half-wave range is 640nm to 670 nm.
The wave peak of the first red light wave band is a first wave peak, the relative optical power corresponding to the first wave peak is 0.9-1, and the wavelength corresponding to the first wave peak is 645 nm-665 nm. Specifically, the relative optical power (i.e., relative light intensity) corresponding to the first peak is 0.9, 0.92, 0.95, 0.99, 1, etc., wherein 1 is preferred. The wavelength corresponding to the first peak can be selected from 645nm, 651nm, 654nm, 659nm, 665nm, etc., wherein 660nm is preferred.
Through the scheme that the red light chip 20 and the blue light chip 30 excite the green medium 40, the half-wave width of the excited first red light wave band is between 15nm and 30nm, so that the energy is concentrated, the red light saturation is high, the wavelength of the first wave peak of the first red light wave band is between 650nm and 670nm, the penetrating power of red light is high, the color and luster of fresh meat are restored well, meanwhile, the relative optical power corresponding to the first wave peak of the first red light wave band is between 0.9 and 1, and the fresh red display effect is good. In addition, the first red light wave band of above-mentioned parameter can reduce the generation of yellow light to a certain extent, avoids the yellow light to influence the demand of giving birth to bright meat to red saturation to further improve the bright illumination colour of giving birth to and restore the degree, avoid appearing the tawny that influences the purchase desire, can demonstrate the red that comparatively matches with giving birth to bright meat.
In one embodiment, referring to FIG. 5, the normalized spectrogram further comprises a green band. The half-wave width of the green light wave band is 35 nm-60 nm. Specifically, the half-wave width of the green light band can be selected from 35nm, 41nm, 48nm, 53nm, 57nm, 60nm and the like, wherein 60nm is preferred, and the half-wave range is 510nm to 570 nm. By setting the half-wave width of the green light wave band between 35nm and 60nm, the green light wave band can not influence the color development effect of the white fresh meat, and can not influence the color development effect of the red fresh meat, so that the process cost is high, the color is easy to be disordered and the white color is easy to be distorted if the half-wave width of the green light wave band is below 35nm, and the color reduction of the white part of the fresh meat is not facilitated; if the half-wave width of the green light wave band is more than 60nm, the proportion of white light occupied by the green light wave band is too large, red light is easily affected, red color is easily distorted, and the color development of red parts of fresh meat is not facilitated.
The peak of the green light wave band is a second peak, the relative optical power corresponding to the second peak is 0.2-0.4, and the wavelength corresponding to the second peak is 530-550 nm.

In one embodiment, referring to fig. 5, the normalized spectrogram further includes a yellow band corresponding to a wavelength range of 585nm to 630nm, and the relative optical power of the yellow band is less than 0.15. Specifically, the left side of the yellow light band is connected with the green light band, and the right side is connected with the red light band. The yellow light band is concave, i.e. the relative optical power of the left and right sides of the yellow light band is higher than that of the middle part. The relative light power of the yellow light trough is lower than 0.15, so that the generation of yellow light is further reduced, the yellow light is prevented from influencing the requirement of fresh meat on red saturation, the brown color is caused, and the red color which is matched with the fresh meat can be presented.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes a blue light band, and the half-wave width of the blue light band is 15nm to 30 nm.

By meeting the requirement that the half-wave width of the blue light wave band is between 15nm and 30nm, the blue light wave band can produce white which meets the requirements of fresh and fresh products, and can not influence the color development of the fresh and fresh red. It can be understood that when the half-wave width of the blue light band is below 15nm, the process is difficult and the requirement for the wafer substrate is high. When the half-wave width of the blue light wave band is more than 30nm, the overall brightness of the wafer is greatly reduced, white light is easily disordered to show a tragic white color, and the vivid effect of the white part is not facilitated.
The wave peak of the blue light wave band is a third wave peak, the relative optical power corresponding to the third wave peak is 0.3-0.5, and the wavelength corresponding to the third wave peak is 445-455 nm. Specifically, the relative optical power of the third peak may be selected to be 0.3, 0.34, 0.39, 0.44, 0.5, and so on. The wavelength corresponding to the third peak can be selected from 445nm, 447nm, 449nm, 451nm, 452nm, 454nm, 455nm, etc., wherein 450nm is preferred. Relative luminous power through setting up the third crest is between 0.3 and 0.5, when not influencing white colour development, can also carry out better red colour development, is favorable to avoiding giving birth to bright illumination distortion. The wavelength corresponding to the second peak is between 445nm and 455nm, so that white meeting the fresh requirement of a white part can be well produced.

Specifically, the left side of the blue light band is connected with the blue light band, and the right side of the blue light band is connected with the green light band. The cyan wavelength band is concave, i.e. the relative optical power corresponding to the left and right sides of the cyan wavelength band is higher than the relative optical power corresponding to the middle part. Relative optical power through setting up the blue or green light trough is less than 0.1, has reduced the formation of blue or green light, avoids the blue or green light to influence the bright red presentation of giving birth to and avoid the blue or green light to influence the bright white presentation of giving birth to, is favorable to improving the bright effect that shows of giving birth to bright meat.
In one embodiment, referring to fig. 5, the normalized spectrogram further includes a violet band, the wavelength range corresponding to the violet band is 350nm to 420nm, and the relative optical power of the violet band is lower than 0.1.
