Optionally, the third lens module 3 may be a lens module with a rectangular light spot, a triangular light spot or other special-shaped light spots, which is not limited herein, and the embodiment of the present application may be adaptively modified based on actual requirements.

In the above-mentioned exemplary embodiment, the three lens modules of the optical lens module may independently realize different light patterns, including but not limited to large circular light spots, small circular light spots and non-circular light spots, and may also realize different light spot superposition by combining light mixing forms to generate light spot effects of other shapes and sizes, thereby realizing multiple light patterns with adjustable light spots, and flexibly adopting fewer lens types to realize abundant light pattern adjustment.

The mounting substrate of the embodiment of the present application may be implemented based on a specific structure, or may be formed by integrally machining and fixing during a machining process, but in order to reduce production cost, the optical lens module of the embodiment of the present application further includes a mounting substrate 4 for mounting a lens, specifically, a basal surface of the first lens 11 is fixedly connected with the mounting substrate 4, and connection surfaces (i.e. top surfaces) are surrounded by the second light emitting surfaces 22 and the third light emitting surfaces 34 of the second lens 21 and the third lens 31, and are fixedly connected with the mounting substrate 4 through the connection surfaces.

In the above-described exemplary embodiment, the optical lens module is configured such that the first lens 11 is disposed higher than the second lens 21 and the third lens 31, and the light emitting direction of the first lens 11 and the light emitting direction of the second lens 21 and the third lens 31 are both upward from the mounting substrate 4, so that if the first lens module 1 is present, the first lens module 1 must be distributed in an upward position, that is, the first light emitting surface 14 of the first lens 11 is higher than the second light emitting surface 22 and the third light emitting surface 34 of the second lens 21 and the third lens 31, and if only the second lens module 2 and the third lens module 3 are disposed at the same height, specifically, the distance between the two light emitting surfaces is the same with respect to the mounting substrate 4. Since the first lens 11 is emitted through the optical working surface, the position setting can avoid the influence of the light path transmitted through the mounting substrate 4, and reduce the optical energy loss of the first lens 11.

The following describes a plurality of combinations of the optical lens module according to the present application with reference to fig. 15 to 26:

Referring to fig. 15 to 17, the optical lens module includes a first lens module 1 and a second lens module 2 that are integrally disposed, the first lens module 1 includes a plurality of first lenses 11, and the plurality of first lenses 11 are circularly distributed on the outer periphery of the second lens module 2.

Considering that the same type of light spots can be realized by the same type of lenses, the optical lens module adopting the centralized combination mode is applied, and the same type of lenses are centralized and close to each other, so that the realization of light spot superposition and mixed light and color mixing is facilitated, and in order to realize a better light spot display effect, the first lens module 1 is preferentially arranged in the central area of the optical lens module.

It should be noted that, although the connection structure of the optical lens module shown in the above embodiment is preferably configured to be circular or rectangular, it may also be configured to be elliptical, annular, etc., and may be adjusted according to practical application requirements, which is not described herein.

In the above-described exemplary embodiments, the optical lens module avoids mutual interference of optical paths between lenses by limiting the distance between the lenses, and has compact structure, small size, low cost, and less limitation on light sources.

In order to reduce the production difficulty and the production cost, the mounting substrate 4, the first lens 11, the second lens 21 and the third lens 31 are made of the same material, for example, but not by way of limitation, the mounting substrate 4 and the lenses are integrally formed by injection molding, and the thickness of the mounting substrate 4 is greater than 1.5 mm so as to prevent the light rays of the mounting substrate 4 which are too thin from being refracted and diffracted therein, and simultaneously ensure the thickness and the structural strength, and the material is a plastic material, such as polymethyl methacrylate (PMMA), polycarbonate (PC) or silica gel.

When the beads are the same, the connection surface area of the second lens 21 is larger than the base surface area of the first lens 11.

The refractive body 362 is disposed around the light refracting surface 361 and is connected to the inner wall reflecting surface of the third lens 31, the refractive body 362 extends from the third light emitting surface 34 to the incident light module 37, the diameter of the refractive body 362 tapers from the third light emitting surface 34 to the incident light module 37, and the bottom surface area of the refractive body 362 is smaller than the top surface area of the refractive body 362. Referring to fig. 8, the refractive body 362 is respectively connected to the third light emitting surface 34 and the inner wall reflecting surface of the third lens 31, and the inner wall reflecting surface of the third lens 31 covers the outer wall of the refractive body 362 to form a parabolic curved surface body tapering in a direction perpendicular to the third light emitting surface 34, and the parabolic curved surface body is used for making the light at the edge of the third light emitting surface 34 totally reflected back to the inner wall reflecting surface, so as to optimize part of the edge light on the light refracting surface 361.

An emitting body 35 is disposed between the third light emitting surface 34 and the refractive optical module 36, the emitting body 35 extends to one end far away from the third light emitting surface 34, the bottom of the emitting body 35 is connected with the top of the refractive body 362, the light refractive surface 361 is disposed at the bottom of the emitting body 35 and corresponds to the position of the light incident hole 371 on the refractive body 362, the third light emitting surface 34 is covered on the top surface of the emitting body 35, and the emitting body 35 is used for supporting the third light emitting surface 34 and the light refractive surface 361. Alternatively, the refractive body 362 is made of a transparent glass material. Is made of transparent glass material.

As shown in fig. 27, the projection of the incident light ray O-C from the light source onto the base surface of the third lens 31 is O-F, wherein the line segment C-F rotates around the O point once to obtain the incident surface 372, the incident surface 372 is disposed around the top third light refracting surface 361, and the incident surface 372 is covered on the inner wall of the light entrance hole 371, and thus the incident surface 372 surrounds the light source in the light entrance hole 371, and the incident surface 372 is connected with the light refracting surface 361 and the base surface. Light emitted from the light source in the light entrance hole 371 has divergent light with a certain beam angle, one part enters the third lens 31 through the incident surface 372, and the other part enters the third lens 31 through the light refracting surface 361 of the refracting light module 36.

In some embodiments, the vertical distance from the second lateral end point 3611 to the third light emitting surface 34 is a first pitch, the vertical distance from the second longitudinal end point 3612 to the third light emitting surface 34 is a second pitch, and the first pitch is smaller than the second pitch, i.e. the second lateral end point 3611 and the second longitudinal end point 3612 have a height difference with respect to the third light emitting surface 34. In the embodiment of the application, the included angle between the connecting line of the two first longitudinal ends 33 and the connecting line of the two second longitudinal ends 3612 is not greater than 45 degrees, and the included angle between the connecting line of the two first transverse ends 32 and the connecting line of the two second transverse ends 3611 is not greater than 45 degrees.

As shown in fig. 28, L is a lens side, T is an air side, an incident light enters the lens side L from the air side T, 0-1 is an incident light, m-1-n is a light incident surface, the incident light 0-1 is perpendicular to the light incident surface m-1-n, and accordingly, an outgoing light 1-2 is outgoing in a direction perpendicular to the light incident surface m-1-n.

As shown in fig. 29, L is a lens side, T is an air side, an incident light enters L from T, 0-1 is an incident light, m-1-n is a light incident surface 372, the incident light 0-1 is incident along a certain angle oblique to the light incident surface 372m-1-n, 1-3 is an extension line of the incident light 0-1, p-1-q is a normal line of the light incident surface 372m-1-n at a light incident point, the light incident angle is +.01q, assuming that the light refractive index of the material is Rf (Rf value is greater than 1), and the exit angle of the incident light at the lens side L is:

∠p12＝asin((sin∠01q)/Rf)；

Because 0 < (sin < 01 q)/Rf < sin < 01q;

So +.p12=asin ((sin +.01q)/Rf) < asin (sin +.01q) = +.01q;

and because the angle 01q and the angle 31p are opposite-vertex angle relations, the angle 01 q= the angle 31p.

So < p12 < 31p, the emergent ray 1-2 is on the right side of the extension line 1-3 of the incident ray 0-1.

As shown in fig. 30, L is a lens side, T is an air side, an incident light enters the lens side L from the air side T, 0-1 is an incident light, m-1-n is a light incident surface 372, the incident light 0-1 is incident along a certain angle oblique to the light incident surface m-1-n, 1-3 is an extension line of the incident light 0-1, p-1-q is a normal line of the light incident surface m-1-n at a light incident point, the light incident angle is +.01q, assuming that the light refractive index of the material is Rf (Rf value is greater than 1), and the exit angle of the incident light at the lens side L is:

∠p12＝asin((sin∠01q)/Rf)；

Because 0 < (sin < 01 q)/Rf < sin < 01q;

So +.p12=asin ((sin +.01q)/Rf) < asin (sin +.01q) = +.01q;

and because the angle 01q and the angle 31p are opposite-vertex angle relations, the angle 01 q= the angle 31p.

So < p12 < 31p, the emergent ray 1-2 is at the left side of the extension line 1-3 of the incident ray 0-1.

Thus, the verification description above in connection with FIGS. 28-30 can be obtained: when an incident ray is incident along a plane inclined to ray incidence plane 372 (i.e., angle of incidence +.01q is not equal to 90 °), an exiting ray is disposed between the extension line of the incident ray and the lower side of ray incidence plane 372, i.e., the exiting ray is inclined to the side of ray incidence plane 372 adjacent to the lower side.

Based on the above conclusion, referring to fig. 27 again, the point O is the setting position of the light source, that is, the incident light is emitted from the point O, when one of the incident light reaches the point C on the light refracting surface 361, the point C is used as the tangent line D-E-C of the light refracting surface 361, and the plane where the tangent line D-E-C is located is regarded as the light incident surface 372, the outgoing light C-J on the lens side is inclined toward the side C-D with a lower adjacent position.

Therefore, the two second lateral endpoints 3611 and the two second longitudinal endpoints 3612 on the light refracting surface 361 of the lens of the present application are provided with a height difference, and the light refracting surface 361 is curved in a direction away from the third light emitting surface 34, so that the incident light on the light source enters the light refracting surface 361 and then is inclined, so that the emitted light is not uniformly emitted in the circumferential direction, and further, the light spot generated on the projection plane is not circular.

In addition, as shown in fig. 31 to 33, in the three cases, 4 'is a light exit point, 5' is a light reflection point, and it is assumed that the lengths of the incident light 4 '-5' are equal in the three cases.

Referring to fig. 8 in combination, an XYZ coordinate system is established on the base surface of the third lens 31, where the Z axis represents displacement in the vertical direction relative to the base surface of the third lens 31, and an outer contour line is obtained by intersecting the inner wall reflecting surface of the third lens 31 with a plane at a certain height z=z0 (Z0 is a certain normal number) in the Z axis direction, and the outer contour line is used to describe a circumferential track line of the inner wall reflecting surface of the third lens 31 at a certain height.

In the first case, as shown in fig. 31, e ' -5 ' -f ' is a tangent line of the outer contour line of the circular spot lens in the prior art, the light incident point 5 ' is on the tangent line e ' -5 ' -f ' of the outer contour line of the circular spot lens, the tangent line e ' -5 ' -f ' of the outer contour line of the circular spot lens is located on the light reflecting surface, the U axis is set to intersect with the V axis and the tangent line e ' -5 ' -f ' of the outer contour line of the circular spot lens, 4 ' -5 ' is the incident light, and the reflected light is 5 ' -6 '. For a circular spot lens, the reflected light is in the same plane as the incident light, the normal 5 ' -g between the incident light 4 ' -5 ' and the reflected light 5 ' -6 ' also coincides with the position of the incident light 4 ' -5 ' and the reflected light 5 ' -6 ', and the normal 5 ' -g is perpendicular to e ' -5 ' -f ', so 4 ' -5 ' is also perpendicular to e ' -5 ' -f ', the triangle Δ4 ' 5 ' f ' is a right triangle.

In the right triangle Δ4 ' 5 ' f ', 4 ' f ' =4 ' 5 '/cos (+.5 ' 4 ' f '), therefore, in the case shown in fig. 9, the section lengths of the light reflecting surface e ' -5 ' -f ' and the U-axis are:

La＝4＇5＇/cos(∠5＇4＇f＇)。

In the second case, as shown in FIG. 32, e '-5' -f 'is a tangent to the outer contour of the third lens 31 of the present application, the tangent e' -5 '-f' to the outer contour of the third lens 31 is located on the light reflecting surface, the U axis is set to intersect with the V axis and the tangent e '-5' -f 'to the outer contour of the third lens 31, 4' -5 'is the incident light, the reflected light is 5' -6 ', and the normal 5' -g is below the incident light 4 '-5'.

In Δ4 '5' f ', 4' -f/sin (+4 '5' f ') =4' -5 '/sin (+4' f '5');

4＇-f＇＝4＇-5＇×(sin(∠4＇5＇f＇)/sin(∠4＇f＇5＇))；

and +.4 ' 5 ' f = +.4 ' 5 ' g +.5 ' f = +.4 ' 5 ' g +90 °;

Whereas in Δ4 '5' f ', 4' 5 '=180° -, 4' 5 'f';

Also +.5 '4' f '=α, +.4' 5 'f' = +.4 '5' g+.g 5 'f' = +.4 '5' g+90°;

therefore, angle 4 ' f ' 5 ' =90° - α— 4 ' 5 ' g;

4＇-f＇＝4＇-5＇×sin(90°+∠4＇5＇g)/sin(90°-α-∠4＇5＇g)。

In the case shown in FIG. 32, the section lengths of the light reflecting surfaces e ' -5 ' -f ' and the U axis are: lb=4 '5' x sin (90++4 '5' g)/sin (90 ° - α - < 4 '5' g).

Also because the 4 '5' is equal in the three cases, there are:

Lb/La＝(sin(90°+∠4＇5＇g)/sin(90°-α-∠4＇5＇g))×cos(∠5＇4＇f＇)；

in Δ4 ' 5 ' f ', 4 ' 5 ' f= 4 ' 5 ' g++g5 ' f ' is less than 180 °;

And +.g5 'f' =90°, so +.4 '5' g < 90 °;

And, 90 DEG < 90 DEG + < 4 ', 5' g < 180 DEG;

so that the number of the parts to be processed, sin (90++4 '5' g) =cos (+4 '5' g);

And cos (+.5 ' 4 ' f ') =cos (α);

Still sin (90 ° - α - < 4 ', 5' g)

＝sin(90°-α)×cos(∠4＇5＇g)-cos(90°-α)×sin(∠4＇5＇g)

＝cos(α)×cos(∠4＇5＇g)-sin(α)×sin(∠4＇5＇g)；

So Lb/la=cos (+.4 '5' g) ×cos (α)/(cos (α) ×cos (+.4 '5' g) -sin (α) ×sin (+.4 '5' g)) > 1;

therefore, lb > La.

In the third case, as shown in fig. 33, e '-5' -f 'is a tangent to the outer contour of the third lens 31, the tangent e' -5 '-f' to the outer contour of the third lens 31 is located on the light reflecting surface, the U axis is set to intersect with the V axis and the tangent e '-5' -f 'to the outer contour of the third lens 31, 4' -5 'is an incident light, the reflected light is 5' -6 ', and the normal 5' -g is above the incident light 4 '-5'.

In Δ4 '5' f ', 4' -f/sin (+4 '5' f ') =4' -5 '/sin (+4' f '5');

4＇-f＇＝4＇-5＇×(sin(∠4＇5＇f＇)/sin(∠4＇f＇5＇))；

∠4＇5＇f＇＝∠g5＇f＇-∠4＇5＇g＝90°-∠4＇5＇g。

Whereas in Δ4 '5' f ', 4' 5 '=180° -, 4' 5 'f';

also +.5 '4' f '=α, +.4' 5 'f' =90° - < 4 '5' g;

Therefore, the angle 4 ' f ' 5 ' =90° - α++4 ' 5 ' g;

thus, 4 '-f' =4 '-5' -xsin (90 ° - < 4 '-5' -g)/sin (90 ° - α+< 4 '-5' -g).

So, as in the case of FIG. 11, the section length of the light reflecting surface e ' -5 ' -f ' and the U axis is:

Lc＝4＇5＇×sin(90°-∠4＇5＇g)/sin(90°-α+∠4＇5＇g)。

also because the 4 '5' is equal in the three cases, there are:

Lc/La＝(sin(90°-∠4＇5＇g)/sin(90°-α+∠4＇5＇g))×cos(∠5＇4＇f＇)；

In Δ4 ' 5 ' f ', the angle g5 ' f=90° = 4 ' 5 ' g + & lt 4 ' 5 ' f ';

so 0 DEG < 4 ', 5' g < 90 DEG;

Therefore sin (90 ° - +.4 '5' g) =cos (+.4 '5' g).

And cos (+.5 ' 4 ' f ') =cos (α);

And sin (90-alpha + < 4 ', 5' g)

＝sin(90°-α)×cos(∠4＇5＇g)+cos(90°-α)×sin(∠4＇5＇g)

＝cos(α)×cos(∠4＇5＇g)+sin(α)×sin(∠4＇5＇g)；

Lc/la=cos (+.4 '5' g) ×cos (α)/(cos (α) ×cos (+.4 '5' g) +sin (α) ×sin (+.4 '5' g)) < 1.

Therefore, lc < La.

In view of the above-mentioned, it is desirable,

The section of the tangent line e ' -5 ' -f ' of the outer contour line of the third lens 31 in the U-axis is longer as described in fig. 32 with reference to the circular spot lens of the related art described in fig. 31. And the tangential line e ' -5 ' -f ' represents the trend of the contour line of the inner wall reflection surface of the third lens 31 in the circumferential direction.

Similarly, lc < La means that the dimension of the inner wall reflection surface 204 of the third lens 31 in the U direction as illustrated in fig. 33 is smaller than that of the circular spot lens of the related art as illustrated in fig. 31.

The reflected light on the inner wall reflection surface 204 of the third lens 31 as described in fig. 32 tends to go toward the V-axis direction more than the circular spot lens of the related art as described in fig. 31.

The reflected light on the inner wall reflection surface 204 of the third lens 31 as illustrated in fig. 33 tends to go toward the U-axis direction more than the circular spot lens of the related art as illustrated in fig. 31.

The light reflection mode of the circular spot lens in the prior art described in fig. 31 is adopted, outgoing light is uniformly distributed in the circumferential direction, and certainly, the outgoing light is also uniformly distributed in the two directions of the U axis and the V axis, and the sizes of the corresponding two directions of the U axis and the V axis are equivalent.

With the light reflection mode of the third lens 31 illustrated in fig. 32, the outgoing light is distributed more in the V-axis direction than in the U-axis direction, and the corresponding U-axis direction dimension is larger than the V-axis direction dimension.

With the light reflection mode of the third lens 31 illustrated in fig. 33, the outgoing light is distributed more than the V-axis direction in the U-axis direction, and the corresponding U-axis direction dimension is smaller than the V-axis direction dimension.

Based on the above analysis, the inner wall reflection surface of the third lens 31 is connected to the exit body 35, and at the connection, the dimensions in the X-axis and Y-axis directions are correspondingly matched so that the refracted light generated on the inner wall reflection surface of the third lens 31 can be emitted through the third light exit surface 34, the incident light is irradiated to different positions of the inner wall reflection surface of the third lens 31 in the Z-axis direction, and total reflection is generated, and the reflected light is emitted through the third light exit surface 34.

By way of illustration of various embodiments of the optical lens module of the present application, it can be seen that the optical lens module embodiments of the present application have at least one or more of the following advantages:

Specifically, since the light emitting direction of the lens module faces the same side of the mounting substrate 4, when there is overlap between the lenses disposed on the upper and lower sides of the mounting substrate 4, the overlapping portion realizes a dual light mixing effect along the light emitting direction, a novel light emitting effect and a light spot are formed, and the size of the overlapping portion can also be used for adjusting the final light mixing effect.
