Detailed Description of the Embodiments

[0020] The present utility model discloses a sensor module with a broadband lens. The following combines with a preferred embodiment (Embodiment 1) and refers to the Figures 1 to 5 drawings to further describe the specific embodiments of the present utility model.

[0021] Referring to the Figures 1 to 5 , Figures 1 to 5 the sensor modules with broadband lenses from different perspectives are respectively shown.

[0022] Example 1 (LED module 310 fixedly connected to base 100).

[0023] Preferably, a sensor module with a broadband lens includes a base 100, a lens module 200, and an LED module 300. The LED module 300 is located between the base 100 and the lens module 200, where:

[0024] The lens module 200 includes a plurality of adjacent and mutually contacting lens modules 210 (the number of lens modules 210 is the same as the number of LED modules 310). The lens module 210 is provided with a contraction part 211 and a main body part 212. One end of the main body part 212 is integrally formed with the contraction part 211, and an aspherical lens 213 is embedded in the other end of the main body part 212, so that the incident light entering the contraction part 211 of the lens module 210 is emitted through the aspherical lens 213 to form the emitted light (emitted from the aspherical lens 213 of the lens module 210).

[0025] The LED module 300 includes a plurality of discrete (non - adjacent and non - mutually contacting) LED modules 310. The LED modules 310 are fixedly connected to the base 100, and the lens module 210 is directly opposite to (corresponding to) the LED module 310, so that the light of the LED module 310 can be as completely incident (enter) into the contraction part 211 of the lens module 210 corresponding to the LED module 310 to form the incident light entering the contraction part 211 of the lens module 210.

[0026] It should be noted that the aspherical lenses 213 embedded in different main body parts 212 can be slightly different (or partially the same), so that the emitted light emitted through different aspherical lenses 213 can cover the spectra of different frequency bands as much as possible, thereby achieving the overall effect of the broadband lens.

[0027] Among them, both the contraction part 211 and the main body part 212 are made of light - shielding materials (that is, opaque materials) to prevent the light emitted from one LED module 210 from entering the adjacent lens module 210, and also to prevent the emitted light emitted through the aspherical lens 213 from entering the adjacent lens module 210, causing light mixing.

[0028] Among them, the lens module 200 further includes a plurality of support columns 220. One end of the support column 220 is fixedly connected to the base 100, and the other end of the support column 220 is fixedly connected to the outer wall of the contraction part 211 (of a certain lens module 210), so that there is a spacing between the LED module 300 and the lens module 200, facilitating the light of the LED module 310 to enter the lens module 210.

[0029] Among them, the LED module 310 includes an LED substrate 311, a wire 312, and an LED lamp bead 313. The LED substrate 311 is fixedly connected to the base 100. The wire 312 is embedded in the LED substrate 311. The LED lamp bead 313 is fixedly connected to the LED substrate 311. One end of the wire 312 is electrically connected to the LED lamp bead 313, and the other end of the wire 312 is electrically connected to a power source (not shown in the figure).

[0030] Among them, the base 100 is provided with a plurality of positioning holes 101 to facilitate the external connection of the base 100 to other devices.

[0031] Among them, the whole body of the main body portion 212 is a regular hexagon so that adjacent lens modules 210 are as adjacent and in contact with each other as possible, increasing the contact area.

[0032] Embodiment 2 (the LED module 310 is detachably connected to the base 100).

[0033] Preferably, a sensor module of a broadband lens includes a base 100, a lens module 200, and an LED module 300. The LED module 300 is located between the base 100 and the lens module 200, where:

[0034] The lens module 200 includes a plurality of adjacent and mutually contacting lens modules 210 (the number of lens modules 210 is the same as the number of LED modules 310). The lens module 210 is provided with a contraction portion 211 and a main body portion 212. One end of the main body portion 212 is integrally formed with the contraction portion 211. The other end of the main body portion 212 is embedded with an aspherical lens 213, so that the incident light entering the lens module 210 (the contraction portion 211) is emitted through the aspherical lens 213 to form an outgoing light (emitted by the aspherical lens 213 of the lens module 210).

[0035] The LED module 300 includes a plurality of discrete (not adjacent and not in contact with each other) LED modules 310. The LED module 310 is detachably connected to the base 100. The lens module 210 is directly opposite to (corresponding to) the LED module 310, so that the light of the LED module 310 can be completely incident (enter) into the lens module 210 (the contraction portion 211) corresponding to the LED module 310 as much as possible, forming the incident light entering the lens module 210 (the contraction portion 211).

[0036] It should be noted that the aspherical lenses 213 embedded in different main body portions 212 can be slightly different (or partially the same), so that the outgoing light emitted through different aspherical lenses 213 can cover different frequency bands of the spectrum as much as possible, thereby realizing the overall effect of the broadband lens.

[0037] Among them, both the contraction part 211 and the main body part 212 are made of light-shielding materials (i.e., opaque materials) to prevent the light emitted by one LED module 210 from entering the adjacent lens module 210, and also to prevent the outgoing light emitted through the aspherical lens 213 from entering the adjacent lens module 210, resulting in light mixing.

[0038] Among them, the lens module 200 further includes a plurality of support columns 220. One end of the support column 220 is fixedly connected to the base 100, and the other end of the support column 220 is fixedly connected to the outer side wall of the contraction part 211 (of a certain lens module 210), so that there is a spacing between the LED module 300 and the lens module 200, facilitating the light of the LED module 310 to enter the lens module 210.

[0039] Among them, the LED module 310 includes an LED substrate 311, a wire 312, and an LED lamp bead 313. The LED substrate 311 is detachably connected to the base 100. The wire 312 is embedded in the LED substrate 311. The LED lamp bead 313 is fixedly connected to the LED substrate 311. One end of the wire 312 is electrically connected to the LED lamp bead 313, and the other end of the wire 312 is electrically connected to a power source (not shown in the figure).

[0040] Among them, the base 100 is provided with a plurality of positioning holes 101 to facilitate the base 100 to be externally connected to other devices.

[0041] Among them, the whole body of the main body part 212 is in a regular hexagon shape, so that adjacent lens modules 210 can be as adjacent and in contact with each other as possible, increasing the contact area.

[0042] It is worth mentioning that the specific selection and other technical features of the LED lamp bead 313 involved in the patent application of the present utility model should be regarded as the prior art. The specific structures, working principles, and possible control methods and spatial arrangement methods of these technical features can be selected conventionally in the art, and should not be regarded as the inventive points of the patent of the present utility model. The patent of the present utility model will not be further specifically elaborated.

[0043] For those skilled in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
