[0026] The embodiment of the utility model is a kind of LED light curing lamp based on double waveband cooperation, including the lamp pearl module one 5 of a plurality of LED light source one 1, the lamp pearl module two 6 of a plurality of LED light source two 2, and the lens one 3 corresponding with LED light source one 1, the lens two 4 corresponding with LED light source two 2, the waveband of the LED light source one 1 is greater than or less than the waveband of LED light source two 2.

[0027] REFERENCE Figure 1 And Figure 2 The utility model mainly uses LED as light source, and simultaneously uses mixed cooperation based on two waveband LED light source one 1 and LED light source two 2, and configures corresponding light distribution lens one 3 or lens two 4, to solve the low photoelectric conversion efficiency, environmental protection, preheating lamp needed when using mercury lamp, and based on the lamp pearl module one 5 and the lamp pearl module two 6 of double waveband cooperation, different levels of printing ink are simultaneously cured, and the curing effect of printing ink is improved. Lens one 3 and lens two 4 respectively collect the light emitted by corresponding LED light source one 1, LED light source two 2 to a certain focal point, to improve the light intensity of the lamp.

[0028] It should be noted that the number of the first lamp bead module 5 and the second lamp bead module 6 is 3:1. The number of the first lamp bead module 5 and the second lamp bead module 6 can be set according to the actual curing needs of the printing ink, so that the number between them satisfies 3:1. Each first lamp bead module 5 or second lamp bead module 6 is provided with LED light source one 1, lens one 3 or LED light source two 2, lens two 4, and different wavelength LED light sources one 1 and LED light source two 2 are configured to improve the curing effect of the LED curing lamp.

[0029] Moreover, the second lamp bead module 6 is located between two first lamp bead modules 5. Since the number of the first lamp bead module 5 is three times the number of the second lamp bead module 6, that is, during the assembly design process, the second lamp bead module 6 needs to be located between the first lamp bead module 5, ensuring that there are two different wavebands between LED light source one 1 and LED light source two 2, so that the waveband of LED light source two 2 and the waveband of LED light source one 1 on both sides produce waveband alternation, based on which the printing ink is simultaneously cured at different levels by the two different wavebands.

[0030] Among them, the waveband in the LED light source one 1 is UVA waveband, and the waveband in the LED light source two 2 is UVB waveband. UVA waveband mainly cures the bottom layer of the printing ink, and UVB waveband mainly cures the surface layer of the printing ink. At the same time, through the cooperation of the corresponding lens one 3 or lens two 4, the light emitted by the LED light source one 1 and the LED light source two 2 is collected at a certain point, realizing the simultaneous curing of the surface layer and the bottom layer of the printing ink, improving the curing effect and shortening the curing time.

The substrate 7 is arranged, and the LED light source one 1 and the LED light source two 2 can be fixedly or detachably installed in the substrate 7. The specific installation mode is the prior art, which is not enumerated one by one here.

[0034] In addition, the focal length of the lens one 3 and the lens two 4 is limited, the LED light source one 1 is provided with the lens one 3 with a focal length of 60 or 100 at the end away from the substrate 7. The LED light source two 2 is provided with the lens two 4 with a focal length of 100 at the end away from the substrate 7. The selection of the lens one 3 can be set according to the actual situation, which is not described here. And the lens one 3 and the lens two 4 are the existing lens devices, and the specific size is not enumerated one by one here.

[0035] In some preferred embodiments, the convex end of the lens one 3 and the convex end of the lens two 4 are both away from the substrate 7. The convex end of the lens one 3 and the convex end of the lens two 4 are respectively away from the substrate 7, which can improve the light emitted by the LED light source one 1 and the LED light source two 2 to be collected into the focal point through the lens one 3 and the lens two 4, and significantly improve the light intensity of the lamp, which is described with reference to Figure 3 .

[0036] The working principle of the utility model is: based on the LED light source one 1 and the LED light source two 2 of double wave band respectively constitute lamp bead module one 5, lamp bead module two 6, make the light emitted by the light source respectively into corresponding lens one 3 and lens two 4 collect in the focal point, improve the light intensity at the focal point, solidify the bottom layer and the surface layer of the printing ink at the same time, improve the solidification effect, shorten the solidification time, do not need preheating, environmental protection.
