The light module 100 provided by the utility model has three kinds of light-emitting effects, and utilizes two kinds of white light beads 321 with different color temperatures to realize color mixing temperature light emission, thereby achieving good lighting effect; the mixed light of the RGB lamp beads 323 and the white light lamp beads 321 and the mixed light of the purple light lamp beads 322 and the white light lamp beads 321 are utilized to realize atmosphere rendering and bacteriostasis effects. The color temperature mixing scheme may be to mix two color temperatures, such as a low color temperature 3000K (not limited to 3000K) and a high color temperature 5000K (not limited to 5000K) white light bead 321, and add a fixed red light chip. For another example, the RGB lamp beads 323+ the white light lamp beads 321 mix light, such as the color temperature 3000K (but not limited to 3000K) of the white light lamp beads 321, and the RGB lamp beads 323, where R is red light lamp beads with a wavelength of 610nm to 630nm (but not limited to this red light band), G is green light lamp beads with a wavelength of 510nm to 530nm (but not limited to this green light band), B is blue light lamp beads with a wavelength of 450nm to 480nm (but not limited to this blue light band), and the effect of multiple colors is achieved by adjusting the brightness of the three colors, and this scheme is mainly used for rendering an environmental atmosphere. For another example, the purple light bead 322+ the white light bead 321 mix light, the white light color temperature is 3000K (but not limited to 3000K), and the purple light bead wavelength is 400nm-430nm, and is mainly used for bacteriostasis and lighting effects. The purple light bead 322 has the light-emitting wavelength of 400nm-430nm, is mainly used for bacteriostasis effect, provides a clean and sterile cooking environment, has the spectrum within the visible light range, and has no harm to human bodies under the condition of short irradiation time.

The utility model discloses light module 100's principle does: when the bacteria are irradiated by purple light or short-wave blue light for a long time, because a large amount of endogenous porphyrin is generated in the metabolism of the bacteria, the endogenous porphyrin can be activated into unstable porphyrin after being irradiated by shorter-wave (such as 405nm) and combined with triplet oxygen to form unstable singlet oxygen, and the singlet oxygen is combined with compounds on cell membranes to damage the cell membranes so as to cause the death of the bacteria. Compared with the sterilization of the existing mercury lamp, the sterilization of the 405nm violet light wave band can avoid the problem of water pollution caused by highly toxic pollutants in the mercury lamp.

The above is only the optional embodiment of the present invention, and not therefore the limit to the patent scope of the present invention, all the concepts of the present invention utilize the equivalent structure transformation of the content of the specification and the attached drawings, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
