In some embodiments, the lamp 100 can be a panel lamp, a wall washer lamp, etc. In this embodiment, the lamp 100 is a light strip, and the light strip can be distinguished according to its light color and the function of the light strip. As an example, the light of the light strip has multiple colors, and the light strip is used to decorate the application environment or to attract people, then the light strip is a neon light strip. As another example, the light color of the light strip is white light or warm light, etc., then the light strip is a lighting light strip.

[0023] In this embodiment, the lamp 100 has a length direction A, a width direction B and a thickness direction C. The size of the lamp 100 in the length direction A is greater than the size in the width direction B, and the size of the lamp 100 in the width direction B is greater than the size in the thickness direction C, so that the lamp 100 is in a strip or strip shape. In this embodiment, the lamp 100 includes a housing 10, a light source module 20 and a lampshade 30. The housing 10 is extended along the length direction A. The size of the housing 10 in the length direction A is substantially the same as the size of the lamp 100 in the length direction A. The size of the housing 10 in the width direction B is substantially the same as the size of the lamp 100 in the width direction B. The housing 10 is provided with a mounting groove 111 on one side of the housing 10 in the thickness direction C, and the mounting groove 111 extends along the length direction A. The light source module 20 is used to emit an illumination beam. The light source module 20 is installed in the mounting groove 111 of the housing 10. The light source module 20 is roughly arranged opposite to the notch of the mounting groove 111. The light-emitting side of the light source module 20 is oriented in the same direction as the notch of the mounting groove 111, so that the illumination beam can be transmitted to the outside of the housing 10 through the notch of the mounting groove 111. In this embodiment, the light source module 20 includes a circuit board (not shown in the figure) and a plurality of lamp beads 22. The circuit board is arranged in the mounting groove 111.

In other embodiments, the light source module 20 can include a plurality of light bulbs connected in series in sequence along the length direction A.

[0024] In this embodiment, the lampshade 30 is connected to the housing 10 and covers the notch of the mounting groove 111. The illumination light beam can pass through the lampshade 30 to be transmitted to the outside of the housing 10. The lampshade 30 has a diverging effect on the illumination light beam, so that the light of the illumination light beam passing through the lampshade 30 is more uniform, thereby improving the illumination effect. In this embodiment, the lampshade 30 is matched with the form of the housing 10 and the mounting groove 111 and is set to a strip or belt structure. The size of the lampshade 30 in the length direction A is roughly the same as the size of the housing 10 in the length direction A. When the lampshade 30 is connected to the housing 10 and covers the mounting groove 111, the size of the combination of the lampshade 30 and the housing 10 in the thickness direction C roughly defines the size of the lamp 100 in the thickness direction C.

[0025] See also Figure 2 and Figure 3 In this embodiment, the lamp 100 further includes an optical lens 40, which is installed in the mounting groove 111. The optical lens 40 is located between the light source module 20 and the notch of the mounting groove 111. The optical lens 40 is located on the optical path of the illumination light beam. The illumination light beam is transmitted to the lampshade 30 after the divergence of the optical lens 40, so as to improve the divergence of the illumination light beam, so that the light emitted by the lamp 100 is more uniform. In this embodiment, the optical lens 40 is matched with the shape of the mounting groove 111, and the optical lens 40 is also set as a strip structure. The size of the optical lens 40 in the length direction A is greater than the size of the optical lens 40 in the width direction B, and greater than the size of the optical lens 40 in the width direction B. In the actual structure, the optical lens 40 is generally arranged in the mounting groove 111 along the length direction A.

[0026] In this embodiment, the optical lens 40 has a light-incoming side 42 and a light-emitting side 43, and the light-incoming side 42 and the light-emitting side 43 are respectively located on both sides of the optical lens 40 in the thickness direction C.

In actual application scenarios, the light source module 20 is installed on the inner wall of the mounting groove 111, and the notch of the mounting groove 111 and the light source module 20 are roughly located on both sides of the housing 10 in the thickness direction C. When the optical lens 40 is installed in the mounting groove 111, the light inlet groove 421 is opposite to the light source module 20, that is, the multiple lamp beads 22 of the light source module 20 are opposite to the light inlet groove 421 of the optical lens 40, and the notch of the light inlet groove 421 faces the light source module 20, so that at least part of the illumination light beam is transmitted to the light inlet groove 421 and enters the inside of the optical lens 40, and after at least one reflection from the optical lens 40, it is transmitted out of the optical lens 40 and enters the light outlet groove 431. The light outlet groove 431 is exposed through the notch of the mounting groove 111, that is, the light outlet groove 431 is connected with the notch of the mounting groove 111, and the illumination light beam in the light outlet groove 431 is transmitted to the lampshade 30 through the notch of the mounting groove 111. Under the configuration of this embodiment, the illumination light beam is transmitted out of the lamp 100 after being diverged by the optical lens 40 and the lampshade 30 , so that the illumination light beam is more uniform after being transmitted out of the housing 10 .

[0027] In the present embodiment, the optical lens 40 is provided with at least two inner holes 44, both of which are arranged between the light inlet groove 421 and the light outlet groove 431, the axis of each inner hole 44 extends substantially along the length direction A, and each inner hole 44 has a reflective wall 441. After the illumination light beam enters the interior of the optical lens 40, at least part of the illumination light beam can be transmitted to the reflective wall 441 and reflected by the reflective wall 441, so as to extend the optical path of the illumination light beam and improve the divergence of the illumination light beam. In the present embodiment, the outer peripheral side surface of the inner hole 44 substantially defines the reflective wall 441. In the present embodiment, the inner hole 44 is arranged along the length direction A at both ends of the optical lens 40 in the length direction A, so that the divergence effect of each part of the optical lens 40 on the illumination light beam is similar, so that the brightness and uniformity of the light emitted by each part of the lamp 100 in the length direction A are similar. In this embodiment, the inner hole 44 is in the form of a continuous through hole. In other embodiments, each inner hole 44 can be replaced by a plurality of air holes or bubbles arranged in sequence along the length direction A to achieve the effect of increasing the divergence of the illumination beam. In this embodiment, the optical lens 40 is an integral lens element. In other embodiments, the optical lens 40 can be a plurality of lens elements of substantially the same shape and structure, and the plurality of lens elements are arranged in sequence along the length direction A in the mounting groove 111.

[0028] In summary, the optical lens 40 in the present embodiment is in a strip-shaped structure, and the optical lens 40 has a length direction A, a width direction B, and a thickness direction C. The optical lens 40 is provided with a light inlet side 42 and a light outlet side 43 on both sides in the thickness direction C, respectively. A light inlet groove 421 is provided on the light inlet side 42, and the light inlet groove 421 extends along the length direction A. A light outlet groove 431 is provided on the light outlet side 43, and the light outlet groove 431 extends along the length direction A. In actual application scenarios, the illumination light beam enters the light inlet groove 421 and enters the interior of the optical lens 40. After being reflected at least once in the optical lens 40, the illumination light beam is transmitted to the light outlet side 43 and at least partially transmitted to the light outlet groove 431, and then transmitted in a direction away from the optical lens 40. In this embodiment, the optical lens 40 is further provided with two inner holes 44, which are located between the light inlet slot 421 and the light outlet slot 431, each inner hole 44 extends along the length direction A, and each inner hole 44 has a reflective wall 441, which has a reflective effect on the illumination light beam. In the process of the illumination light beam being transmitted from the light inlet slot 421 to the light outlet slot 431, at least part of the light beam is transmitted to the reflective wall 441 and reflected by the reflective wall 441, so as to extend the optical path of the illumination light beam, so as to make the divergence degree of the illumination light beam higher.

[0029] Under the setting of this embodiment, the optical lens 40 has a divergent effect on light. Specifically, after the illumination light beam enters the interior of the optical lens 40 through the light inlet groove 421, it can be transmitted to the mirror surface of the optical lens 40 at least once and reflected, so as to increase the optical path of the illumination light beam. The inner hole 44 on the optical lens 40 has a reflective wall 441, and at least part of the illumination light beam can be transmitted to the reflective wall 441 and reflected by the reflective wall 441, so as to further extend the optical path of the illumination light beam. After being folded multiple times inside the optical lens 40, the illumination light beam is transmitted to the light outlet groove 431 and away from the optical lens 40, so that the illumination light beam passing through the optical lens 40 is more uniform. When the optical lens 40 is applied to the lamp 100, the optical lens 40 can diverge the illumination light beam to a large extent to achieve the effect of uniform light of the lamp 100. In this embodiment, a lampshade 30 with a smaller size in the thickness direction C can be selected to reduce the size of the lamp 100 in the thickness direction C, so as to reduce the volume of the lamp 100. In actual application scenarios, the size of the lamp 100 in the thickness direction C can be reduced to a range of 7.5 mm to 10 mm (including 7.5 mm and 10 mm), for example, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, etc.

[0030] In the present embodiment, the inner hole 44 is in the form of a through hole whose axis extends along the length direction A, and the inner hole 44 has a positive cross section, which is a cross section perpendicular to the length direction A. In the present embodiment, the contour of the positive cross section may include one of a straight line and an arc line, and the arc line refers to a line with a fixed center of a circle. In other embodiments, the contour of the positive cross section may also include a line that does not have a fixed circle. As an example, the positive cross section includes a plurality of straight lines that are connected at the ends, so that the inner hole 44 is in the form of a cylindrical through hole. For example, the contour of the positive cross section in the present embodiment is a triangle, and the inner hole 44 is in the form of a triangular prism-shaped through hole. As another example, the contour of the positive cross section is a perfect circle, so that the inner hole 44 is in the form of a cylindrical through hole.

[0031] See also Figure 3 and Figure 4In this embodiment, the optical lens 40 includes two lens portions 41 connected to each other, and the two lens portions 41 are arranged in parallel along the width direction B.

In other embodiments, each lens portion 41 can be provided with two or more lens portions 41 to further extend the optical path of the illumination light beam. In this embodiment, the two lens portions 41 are connected and define a light inlet groove 421 and a light outlet groove 431. Specifically, each lens portion 41 has a first side portion 412 and a second side portion 413 in the width direction B, and the size of the first side portion 412 in the thickness direction C is greater than the size of the second side portion 413 in the thickness direction C. The optical lens 40 has a reference plane (not shown in the figure), which is parallel to the straight line in the length direction A and perpendicular to the straight line in the width direction B. The two lens portions 41 are mirror-symmetrical about the reference plane. The second side portions 413 of the two lens portions 41 are connected so that the optical lens 40 is thin in the middle and thick on both sides in the width direction B. The light inlet groove 421 and the light outlet groove 431 are roughly located at the thinner part of the optical lens 40 and are respectively located on both sides of the optical lens 40 in the thickness direction C.

[0032] See also Figure 2 , Figure 3 and Figure 5 In this embodiment, each lens portion 41 is provided with a light inlet surface 414 and a light outlet surface 415, and the light inlet surface 414 and the light outlet surface 415 are respectively located on opposite sides of the second side portion 413 in the thickness direction C, the light inlet surface 414 faces the light source module 20, and the light outlet surface 415 faces the mounting groove 111. In this embodiment, the distance between the light inlet surface 414 and the light outlet surface 415 in the thickness direction C gradually decreases along the direction from the first side portion 412 to the second side portion 413, so that the size of the first side portion 412 in the thickness direction C is greater than the size of the second side portion 413 in the thickness direction C. In this embodiment, the second side portions 413 of the two lens portions 41 are connected, and the light inlet surfaces 414 of the two lens portions 41 intersect and define a light inlet groove 421, which is located on the light inlet side 42 of the optical lens 40, and the opening of the light inlet groove 421 faces the light source module 20. The light emitting surfaces 415 of the two lens portions 41 intersect and define a light emitting groove 431, which is located at the light emitting side 43 of the optical lens 40, and the opening of the light emitting groove 431 faces the opening of the mounting groove 111. In this embodiment, the light inlet surface 414 and the light emitting surface 415 can be an integral plane or curved surface, or a spliced ​​surface, and the spliced ​​surface includes at least one of a plane and a curved surface.

[0033] In this embodiment, each lens portion 41 is provided with a reflective surface 422, and the reflective surface 422 is connected to the light-incoming surface 414. The reflective surface 422 and the light-incoming surface 414 of each lens portion 41 are arranged and connected in the direction from the first side portion 412 to the second side portion 413. When the two lens portions 41 are connected, the two reflective surfaces 422 are respectively connected to the two opposite sides of the light-incoming groove 421 in the width direction B. The two reflective surfaces 422 are located on the light-incoming side 42 of the optical lens 40. The two reflective surfaces 422 and the light-incoming groove 421 roughly constitute the light-incoming side 42 of the optical lens 40. In this embodiment, the two reflective surfaces 422 are planes, and the reflective surfaces 422 are perpendicular to the straight line in the thickness direction C. The light-incoming groove 421 is opposite to the light source module 20, and the light-incoming groove 421 is concave relative to the reflective surface 422 in the direction away from the light source module 20, so that the light-incoming groove 421 is in the form of a groove body 11. In other embodiments, the reflective surface 422 may be a curved surface or a spliced ​​surface.

[0034] In the present embodiment, the light source module 20 includes a circuit board and a plurality of lamp beads 22 arranged on the circuit board. The lamp beads 22 are "point light sources". The light emitted by each two adjacent lamp beads 22 intersect with each other to intersect the plurality of "point light sources" to form a "line light source", that is, an illumination beam. The illumination beam is a "line light source" extending along the length direction A and transmitted along the width direction B. The illumination beam has left and right sides on the length direction A, which are arranged at an angle and define the divergence angle of the illumination beam. In the present embodiment, the light on the left and right sides of the illumination beam in the length direction A are roughly symmetrical about the reference plane to be mirror-set. In the present embodiment, a portion of the light beam near the edge of the divergence angle in the illumination beam is defined as a first light beam. Due to the mirror-symmetric feature of the illumination beam, the illumination beam includes two first light beams, which are respectively located on both sides of the reference plane and are mirror-symmetric about the reference plane. The two first light beams correspond to the two lens portions 41 one by one, respectively, and each first light beam is transmitted to a corresponding lens portion 41.

[0035] See also Figure 5 and Figure 6 Specifically, the path of the first light beam transmitted from the light source module 20 to the outside of the lamp 100 is roughly as follows: the light source module 20 emits the first light beam, the first light beam enters the light inlet groove 421 and is transmitted to a corresponding lens portion 41, is transmitted through the light inlet surface 414 to enter the interior of the lens portion 41, is transmitted to the reflective wall 441 of the inner hole 44 and is reflected by the reflective wall 441, is reflected to the reflective surface 422 and is reflected by the reflective surface 422, is reflected to the light emitting surface 415 and is transmitted through the light emitting surface 415, enters the light emitting groove 431, is transmitted out of the light emitting groove 431, is transmitted to the lampshade 30 through the notch of the mounting groove 111, and is transmitted through the lampshade 30 to be transmitted to the outside of the lamp 100. Under the setting of this embodiment, the optical path of the first light beam is greatly extended so that the first light beam is fully divergent.

[0036] In this embodiment, each lens portion 41 is provided with an abutting surface 432, and the abutting surface 432 is connected to the light emitting surface 415. The abutting surface 432 and the light emitting surface 415 of each lens portion 41 are arranged and connected along the direction from the first side portion 412 to the second side portion 413. When the two lens portions 41 are connected, the two abutting surfaces 432 are arranged in parallel and spaced apart along the width direction B, and the two abutting surfaces 432 are respectively connected to the opposite sides of the light emitting groove 431 in the width direction B. The two abutting surfaces 432 are located on the light emitting side 43 of the optical lens 40, and the two abutting surfaces 432 and the light emitting groove 431 roughly constitute the light emitting side 43 of the optical lens 40. In this embodiment, the two abutting surfaces 432 are planes, the abutting surfaces 432 are perpendicular to the straight line in the thickness direction C, the light exit groove 431 is opposite to the opening of the mounting groove 111, and the light exit groove 431 is recessed relative to the abutting surface 432 in the direction toward the light input side 42 and the light source module 20, so that the light exit groove 431 is in the shape of the groove body 11. In other embodiments, the abutting surface 432 can be a curved surface or a splicing surface.

[0037] In this embodiment, the shell 10 includes a slot body 11 and two extension portions 12. The slot body 11 is a strip-shaped structure and extends along the length direction A. The slot body 11 defines a mounting slot 111. The two extension portions 12 are strip-shaped ribs. The two extension portions 12 are respectively connected to the two sides of the slot opening of the mounting slot 111 (the two sides of the mounting slot 111 in the width direction B). Each extension portion 12 extends relative to the slot body 11 toward the center of the mounting slot 111, that is, the two extension portions 12 cover part of the slot opening of the mounting slot 111. In the present embodiment, when the optical lens 40 is installed in the mounting groove 111, the two extensions 12 correspond to the two abutting surfaces 432 one by one, and each extension 12 covers the corresponding abutting surface 432, that is, each abutting surface 432 is connected to a corresponding extension 12. In the present embodiment, the abutting surface 432 and the extension 12 abut each other, so that the light transmitted through the abutting surface 432 is absorbed (or diffusely reflected) by the extension 12, so as to avoid that part of the light is transmitted out of the mounting groove 111 without a large degree of divergence, and to avoid that there is strong light in the light transmitted out of the lamp 100. In the present embodiment, the abutting surface 432 and the extension 12 can be connected by an adhesive to keep the position state of the two stable. In the present embodiment, the distance between the two extensions 12 in the width direction B is smaller than the distance between the optical lens 40 in the width direction B, so as to avoid that the optical lens 40 falls off the mounting groove 111. In this embodiment, the size of the mounting groove 111 in the thickness direction C can be set to be smaller, so as to limit the optical lens 40 from rotating in the mounting groove 111 and falling out of the mounting groove 111 .

[0038] See also Figure 5 , Figure 6 and Figure 7In this embodiment, the partial light beam in the illumination light beam close to the reference plane is defined as the second light beam. Due to the mirror symmetry of the illumination light beam, the illumination light beam includes two second light beams, which are respectively located on both sides of the reference plane and are mirror symmetric with respect to the reference plane. The two second light beams correspond to the two lens portions 41 one by one, respectively, and each second light beam is transmitted to a corresponding lens portion 41. The illumination light beam in this embodiment has an optical axis, which may refer to the optical axis of any lamp bead 22.

Under the setting of this embodiment, the optical path of the second light beam is greatly extended so that the second light beam is fully divergent.

[0040] In this embodiment, each lens portion 41 is further provided with a folding surface 411, which is located at the first side portion 412 of the lens portion 41, and the folding surface 411 is connected between the reflecting surface 422 and the abutting surface 432.

In this embodiment, the bending surface 411 is located on the optical path of the first light beam. Specifically, the path of the first light beam transmitted from the light source module 20 to the outside of the lamp 100 is roughly as follows: the light source module 20 emits the first light beam, the first light beam enters the light inlet groove 421 and is transmitted to a corresponding lens portion 41, transmits the light inlet surface 414 to enter the interior of the lens portion 41, is transmitted to the reflective wall 441 of the inner hole 44 and is reflected by the reflective wall 441, is reflected to the reflective surface 422 and is reflected by the reflective surface 422, is reflected to the bending surface 411 and is reflected, is reflected to the light emitting surface 415 and transmits the light emitting surface 415, enters the light emitting groove 431, is transmitted out of the light emitting groove 431, is transmitted to the lampshade 30 through the notch of the mounting groove 111, and is transmitted through the lampshade 30 to be transmitted to the outside of the lamp 100.

[0041] In this embodiment, the turning surface 411 is located on the optical path of the second light beam. Specifically, the path of the second light beam transmitted from the light source module 20 to the outside of the lamp 100 is roughly as follows: the light source module 20 emits a first light beam, the first light beam enters the light inlet groove 421 and is transmitted to a corresponding lens portion 41, is transmitted through the light inlet surface 414 to enter the interior of the lens portion 41, is transmitted to the light emitting surface 415 and is totally reflected, is reflected to the abutting surface 432 and is totally reflected, is reflected to the turning surface 411 and is reflected, is reflected to the reflecting surface 422 and is reflected, is reflected to the light emitting surface 415 and is transmitted through the light emitting surface 415, enters the light emitting groove 431, is transmitted out of the light emitting groove 431, is transmitted to the lampshade 30 through the notch of the mounting groove 111, and is transmitted through the lampshade 30 to be transmitted out of the lamp 100. Under the setting of this embodiment, the turning surface 411 further extends the optical path of the first light beam and the second light beam, so that the first light beam and the second light beam are fully divergent.

[0042] See also Figure 6 , Figure 7 and Figure 8In this embodiment, the illumination light beam further includes two third light beams, the two third light beams are respectively located on both sides of the reference plane, and in the first light beam, the second light beam, and the third light beam located on the same side of the reference plane, the second light beam is located between the first light beam and the third light beam. Under the setting of this embodiment, the angle between the optical axis of the third light beam and the optical axis of the illumination light beam is smaller than the angle between the optical axis of the first light beam and the optical axis of the illumination light beam, and the angle between the optical axis of the third light beam and the optical axis of the illumination light beam is larger than the angle between the optical axis of the second light beam and the optical axis of the illumination light beam, and here the optical axis of the third light beam roughly coincides with a ray of light at the center of the third light beam.

[0043] See also Figure 3 , Figure 5 and Figure 8 In this embodiment, the inner wall of the mounting groove 111 includes two diffuse reflection walls 1111, and the two diffuse reflection walls 1111 are arranged side by side and spaced apart relative to each other along the width direction B. When the optical lens 40 is arranged in the mounting groove 111, the optical lens 40 is located between the two diffuse reflection walls 1111. The optical lens 40 has two folding surfaces 411 spaced apart along the width direction B, and the two folding surfaces 411 correspond to the two diffuse reflection walls 1111 one by one and are arranged relative to each other. Part of the light transmitted through the folding surfaces 411 can be transmitted to the diffuse reflection walls 1111 and diffusely reflected, so as to extend the optical path of the part of the light.

[0044] Specifically, the path of the third light beam transmitted from the light source module 20 to the outside of the lamp 100 is roughly as follows: the light source module 20 emits the third light beam, the third light beam enters the light inlet groove 421 and is transmitted to a corresponding lens portion 41, transmits the light inlet surface 414 to enter the interior of the lens portion 41, is transmitted to the reflective wall 441 of the inner hole 44 and is reflected, is reflected to the light emitting surface 415 and is totally reflected, is reflected to the turning surface 411 and transmits the turning surface 411. When the inner wall of the housing 10 is set as a reflective inner wall, the third light beam transmitted through the turning surface 411 is diffusely reflected when it is transmitted to the inner wall of the housing 10. In this embodiment, after the third light beam is diffusely reflected by the inner wall of the housing 10, part of the third light beam enters the interior of the optical lens 40 again for the next round of folding until it is lost or transmitted to the light emitting groove 431. Under the setting of this embodiment, the optical path of the third light beam is greatly extended so that the third light beam is fully divergent.

[0045] See also Fig. 9 and Fig.10In this embodiment, the reflective wall 441 is located on the optical paths of the first light beam and the third light beam, and the first light beam and the second light beam are respectively transmitted to different positions of the reflective portion of the inner hole 44. Specifically, the reflective wall 441 in this embodiment includes a first reflective portion 4411 and a second reflective portion 4412, and the first reflective portion 4411 and the second reflective portion 4412 are arranged around the circumference of the inner hole 44. In actual application scenarios, the first light beam passes through the light-incoming surface 414, the first reflective portion 4411, the reflective surface 422, the folding surface 411, and the light-emitting surface 415 of the lens portion 41 in sequence; the third light beam passes through the light-incoming surface 414, the second reflective portion 4412, the light-emitting surface 415, and the folding surface 411 of the lens portion 41 in sequence.

[0046] See also Figure 2 In this embodiment, the lampshade 30 includes a first light-transmitting portion 31 and a second light-transmitting portion 32 connected to each other, the first light-transmitting portion 31 is located on the side of the second light-transmitting portion 32 facing the mounting groove 111, the first light-transmitting portion 31 is opposite to the notch of the mounting groove 111 and receives the illumination light beam, and the illumination light beam is sequentially transmitted to the first light-transmitting portion 31 and the second light-transmitting portion 32. It should be understood that the second light-transmitting portion 32, the first light-transmitting portion 31 and the housing 10 are sequentially arranged along the thickness direction C of the housing 10.

[0047] In this embodiment, the first light-transmitting portion 31 and the second light-transmitting portion 32 are at least partially spaced apart to define a light-mixing space 33, and the axial direction of the light-mixing space 33 extends along the length direction A. The arrangement of the light-mixing space 33 enables the lamp 100 to achieve uniform light mixing. The inner wall of the light-mixing space 33 includes a side surface of the first light-transmitting portion 31 facing the second light-transmitting portion 32, and a side surface of the second light-transmitting portion 32 facing the first light-transmitting portion 31. In this embodiment, the cross-sectional profile of the light-mixing space 33 is roughly elliptical, and the arc-shaped inner wall of the light-mixing space 33 has a divergent effect on the illumination beam. In the process of the illumination beam sequentially transmitting the first light-transmitting portion 31 and the second light-transmitting portion 32, the illumination beam can be diverged again to further improve the divergence degree of the illumination beam.

[0048] In this embodiment, the first light-transmitting portion 31 is substantially in the form of a concave lens structure, so that the first light-transmitting portion 31 has a diverging effect on the illumination light beam. The second light-transmitting portion 32 may also be substantially in the form of a concave lens structure, so that the second light-transmitting portion 32 also has a diverging effect on the illumination light beam, so as to increase the divergence of the illumination light beam, so as to form a soft lighting effect. In this embodiment, the side of the second light-transmitting portion 32 that is away from the first light-transmitting portion 31 (i.e., part of the outer surface of the lamp 100) is a convex surface, so as to improve the aesthetics of the lamp 100.

[0049] The present embodiment provides an optical lens 40, which is in a strip-shaped structure and has a length direction A, a width direction B, and a thickness direction C. The optical lens 40 is provided with a light-incoming side 42 and a light-outgoing side 43 on both sides in the thickness direction C, respectively. A light-incoming groove 421 is provided on the light-incoming side 42, and the light-incoming groove 421 extends along the length direction A. A light-outgoing groove 431 is provided on the light-outgoing side 43, and the light-outgoing groove 431 extends along the length direction A. In an actual application scenario, an illumination light beam enters the light-incoming groove 421 and enters the interior of the optical lens 40. After at least one reflection in the optical lens 40, the illumination light beam is transmitted to the light-outgoing side 43 and at least partially transmitted to the light-outgoing groove 431, and then transmitted in a direction away from the optical lens 40. In this embodiment, the optical lens 40 is further provided with two inner holes 44, which are located between the light inlet slot 421 and the light outlet slot 431, each inner hole 44 extends along the length direction A, and each inner hole 44 has a reflective wall 441, which has a reflective effect on the illumination light beam. In the process of the illumination light beam being transmitted from the light inlet slot 421 to the light outlet slot 431, at least part of the light beam is transmitted to the reflective wall 441 and reflected by the reflective wall 441, so as to extend the optical path of the illumination light beam, so as to make the divergence degree of the illumination light beam higher.

[0050] Under the setting of this embodiment, the optical lens 40 has a divergent effect on light. Specifically, after the illumination light beam enters the interior of the optical lens 40 through the light inlet groove 421, it can be transmitted to the mirror surface of the optical lens 40 at least once and reflected, so as to increase the optical path of the illumination light beam. The inner hole 44 on the optical lens 40 has a reflective wall 441, and at least part of the illumination light beam can be transmitted to the reflective wall 441 and reflected by the reflective wall 441, so as to further extend the optical path of the illumination light beam. After being folded multiple times inside the optical lens 40, the illumination light beam is transmitted to the light outlet groove 431 and away from the optical lens 40, so that the illumination light beam passing through the optical lens 40 is more uniform. When the optical lens 40 is applied to the lamp 100, the optical lens 40 can diverge the illumination light beam to a large extent to achieve the effect of uniform light of the lamp 100. In this embodiment, a lampshade 30 with a smaller size in the thickness direction C can be selected to reduce the size of the lamp 100 in the thickness direction C, so as to reduce the volume of the lamp 100.
