DETAILED DESCRIPTION
[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
[0030] See also Figure 1 and Figure 2 The embodiment of the present application provides a lamp 100, which can be used to illuminate the application environment in which it is located, or as a lighting decoration to create a scene light atmosphere. Among them, the lamp 100 can be a neon light strip, a panel light, a wall washer, etc. Taking the lamp 100 of the embodiment of the present application as an example of a neon light strip, the lamp 100 in this embodiment can include a housing 10, a light source module 40, a lampshade 20 and an optical lens 30. The housing 10 serves as the installation structure foundation of the lamp 100, and is provided with a mounting groove 11, which can be used to accommodate components such as the light source module 40 and the optical lens 30. The lampshade 20 is connected to the housing 10 and can cover the notch of the mounting groove 11 to close the mounting groove 11, which can prevent dust or water vapor from entering the mounting groove 11. The lampshade 20 can also hinder the air from circulating inside and outside the mounting groove 11, and can delay the oxidation process of the light source module 40 and the optical lens 30. When the lampshade 20 and the housing 10 are in a connected and matched state, the lampshade 20 and the housing 10 together define an overall appearance structure of the lamp 100 .
[0031] See also Figure 2In this embodiment, the light source module 40 is arranged in the mounting groove 11, and the inner wall of the mounting groove 11 can receive the illumination light beam emitted by the light source module 40. A first reflection wall 121 is arranged on the inner wall of the mounting groove 11 in this embodiment, and the first reflection wall 121 has a reflection effect on the illumination light beam. Different forms of the first reflection wall 121 have different reflection effects. In this embodiment, the first reflection wall 121 is roughly in a planar form, but the surface of the first reflection wall 121 is a diffuse reflection surface, which has a certain degree of roughness. Therefore, in this embodiment, the first reflection wall 121 has a diffuse reflection effect on the illumination light beam, and has a good divergence effect on the illumination light beam.
[0032] See also Figure 2 and Figure 3 In this embodiment, the optical lens 30 has a light-incoming surface 32, a reflecting surface 34, and a light-emitting surface 33 which are sequentially arranged around each other. The reflecting surface 34 and the light-emitting surface 33 are respectively located on opposite sides of the optical lens 30. The light-incoming surface 32 is connected between the reflecting surface 34 and the light-emitting surface 33. The light-incoming surface 32, the reflecting surface 34, and the light-emitting surface 33 are arranged around each other and define the general outline of the optical lens 30. In this embodiment, the light-incoming surface 32 is arranged opposite to the light source module 40, the reflecting surface 34 is arranged opposite to the first reflecting wall 121, the light-emitting surface 33 is approximately located at the notch position of the mounting groove 11, the light-emitting surface 33 is exposed from the housing 10 through the notch of the mounting groove 11, and the light-emitting surface 33 is arranged opposite to the lampshade 20. It should be understood that in order to facilitate the distinction of the multiple side surfaces of the optical lens 30, the present embodiment defines three of the surfaces as the light-incoming surface 32, the light-outgoing surface 33 and the reflecting surface 34, and the optical effects of the three on the illumination beam are not limited, and the specific optical effects of the three on the illumination beam are related to factors such as the incident angles of the illumination beam on the three surfaces respectively.
[0033] See also Figure 4The optical lens 30 in this embodiment is located on the optical path of the illumination light beam emitted by the light source module 40. The illumination light beam has a first light beam L1. The first light beam L1 first transmits through the light surface 32 to be transmitted into the interior of the optical lens 30. After the first light beam L1 enters the optical lens 30, it is transmitted inside the optical lens 30 and then transmitted out of the optical lens 30 via the reflective surface 34. The light path direction of the first light beam L1 before entering the transmission optical lens 30 and the light path direction after being transmitted out of the optical lens 30 are changed, and the first light beam L1 is transmitted to the first reflective wall 121. The first light beam L1 is transmitted to the reflective surface 34 again under the diffuse reflection of the first reflective wall 121, then transmits through the reflective surface 34 to enter the interior of the optical lens 30, and finally transmits through the light surface 33 to be transmitted to the lampshade 20 and emitted. In this embodiment, the first reflective wall 121 and the reflective surface 34 are arranged at intervals to further increase the optical path of the first light beam L1 and improve the uniformity of the first light beam L1. In some other embodiments, the first reflective wall 121 and the reflective surface 34 can be abutted to facilitate installation and improve the installation stability of the optical lens 30.
[0034] In this embodiment, the optical lens 30 is a transparent silicone lens, which can reduce the light loss of the illumination light beam during the transmission process, and the transparent silicone lens has a certain elastic deformation ability, a relatively tough structure, not easy to damage, and is easy to assemble, store or transport. In other embodiments, the optical lens 30 can be a transparent glass lens, a transparent acrylic lens, etc.
[0035] In summary, in this embodiment, before the illumination light beam is transmitted to the lampshade 20, it is deflected twice by the optical lens 30 and reflected once by the first reflective wall 121, so that the optical path of the illumination light beam is greatly extended, and the illumination light beam is fully diverged, so that there are fewer light beams with greater light intensity in the illumination light beam, so that the illumination light beam transmitted to the lampshade 20 is more uniform, and thus the lamp 100 has a softer lighting effect. Under the setting of this embodiment, the optical lens 30 and the first reflective wall 121 have a good divergence effect on the illumination light beam, and the illumination light beam is relatively uniform when it is transmitted to the lampshade 20, so a relatively light and thin lampshade 20 can be selected, and the light and thin lampshade 20 also has a certain degree of divergence effect on the light beam, which can meet the user's requirements for uniform or soft light output of the lamp 100, so that the lamp 100 is relatively light and thin as a whole, and the structure of the lamp 100 is simple, smooth and tends to be flat.
[0036] See also Figure 2In this embodiment, the inner wall of the mounting groove 11 is further provided with a second reflecting wall 122, and the second reflecting wall 122 is connected to the side of the first reflecting wall 121 away from the light-incoming surface 32. In this embodiment, the side of the light-emitting surface 33 away from the light-incoming surface 32 extends toward the direction close to the reflecting surface 34, so that the second reflecting wall 122 is arranged opposite to a part of the light-emitting surface 33. Under the arrangement of this embodiment, the propagation path of the illumination light beam in the mounting groove 11 is more abundant. As an example, the illumination light beam transmits the optical lens 30 and is guided out through the light-emitting surface 33 and is guided to the second reflecting wall 122. As another example, after the illumination light beam enters the interior of the optical lens 30, it is guided to one of the surfaces of the optical lens 30, and after passing through the full reflection effect of the surface at least once, it is guided out through the light-emitting surface 33 and is guided to the second reflecting wall 122.
[0037] See also Figure 5 and Figure 6 In this embodiment, the second reflective wall 122 has a diffuse reflection effect on the illumination light beam, and the illumination light beam has more conduction directions under the reflection effect of the second reflective wall 122. As an example, part of the illumination light beam is conducted to the lampshade 20 after being reflected by the second reflective wall 122 and is emitted from the mounting groove 11, i.e., the lamp 100 through the lampshade 20. As another example, part of the illumination light beam is conducted to the optical lens 30 again after being reflected by the second reflective wall 122 and propagates in the optical lens 30, and then is conducted out of the optical lens 30 through the light emitting surface 33 and is emitted through the lampshade 20.
[0038] As can be seen from the above, in this embodiment, at least a portion of the surface of the light emitting surface 33 is arranged opposite to the second reflecting wall 122. The illumination light beam enters the interior of the optical lens 30 through the light inlet surface 32, and the illumination light beam can be emitted from the optical lens 30 through the reflecting surface 34 and transmitted to the first reflecting wall 121, and can also be emitted from the optical lens 30 through the light emitting surface 33 and transmitted to the second reflecting wall 122.
[0039] See also Figure 5 and Figure 6In this embodiment, the light emitting surface 33 may include a first light emitting portion 331 and a second light emitting portion 332, the first light emitting portion 331 is connected between the light inlet surface 32 and the second light emitting portion 332, and the second light emitting portion 332 is connected between the first light emitting portion 331 and the reflecting surface 34, that is, the light inlet surface 32, the first light emitting portion 331, the second light emitting portion 332 and the reflecting surface 34 are sequentially arranged around. In this embodiment, the first light emitting portion 331 and the second light emitting portion 332 may have a variety of forms, such as a plane or a curved surface, and thus the light emitting surface 33 also has a variety of forms. In this embodiment, the first light emitting portion 331 and the second light emitting portion 332 may both be optical curved surfaces, and the first light emitting portion 331 and the second light emitting portion 332 are smoothly connected, so that the light emitting surface 33 is a continuous optical curved surface and a convex curved surface protruding toward the lampshade 20, so that the illumination light beam is transmitted from the first light emitting portion 331 to the second light emitting portion 332.
[0040] See also Figure 7 In another implementation of the present embodiment, the first light emitting portion 331 and the second light emitting portion 332 are both optical planes, and the two optical planes can be connected or spaced. The two optical planes form an angle. In this implementation of the present embodiment, the angle between the first light emitting portion 331 and the second light emitting portion 332 of the optical plane type is in the range of: greater than or equal to 135° and less than 180°, for example, the angle can be 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, etc. In some embodiments, the light emitting surface 33 can also be a complete optical plane, which can be understood as the angle between the first light emitting portion 331 and the second light emitting portion 332 can be 180°. In this embodiment, after the illumination light beam is transmitted to the complete optical plane light emitting surface 33, it is immediately transmitted to the second reflective wall 122. In some other embodiments, the light emitting surface 33 may include more than two light emitting parts, and the multiple light emitting surfaces 33 may be a combination of an optical plane and an optical curved surface, and the multiple light emitting parts are sequentially connected between the light incident surface 32 and the reflecting surface 34 .
[0041] See also Figure 2 and Figure 3 In this embodiment, the side of the optical lens 30 facing the light source module 40 includes the aforementioned light inlet surface 32 and the installation reference surface 35, and the installation reference surface 35 is used to connect between the light inlet surface 32 and the light outlet surface 33, or to connect between the light inlet surface 32 and the reflection surface 34. In this embodiment, the light source module 40 includes a lamp bead 41 with a divergence angle of about 180°. When the optical lens 30 and the light source module 40 are in the installed state, there is a beam of light with a beam angle close to 0 in the light beam emitted by the lamp bead 41, which is approximately perpendicular to the installation reference surface 35.
[0042] See also Figure 3 and Figure 4 In this embodiment, a light inlet cavity 31 is recessed on one side of the optical lens 30 facing the light source module 40, and the illumination light beam emitted by the light source module 40 can be transmitted into the light inlet cavity 31. The inner surface of the light inlet cavity 31 is bent and defines a light inlet surface 32. After the illumination light beam is transmitted to the light inlet surface 32, it is transmitted through the light inlet surface 32 to be transmitted into the interior of the optical lens 30. Under the setting of this embodiment, the incident angle of the illumination light beam on the bent light inlet surface 32 can be reduced, so that more light beams can be transmitted into the interior of the optical lens 30, and part of the illumination light beam is prevented from being directly transmitted to the lampshade 20 under the reflection effect of the planar light inlet surface 32, so as to avoid the formation of a brighter and protruding light spot on the lampshade 20.
[0043] See also Figure 3 and Figure 4 In this embodiment, the light-incoming surface 32 includes a first light-receiving surface 321 and a second light-receiving surface 322 connected to each other, and the first light-receiving surface 321 and the second light-receiving surface 322 are partial outer surfaces of the optical lens 30. Part of the illumination light beam can be transmitted to the first light-receiving surface 321 and transmitted into the optical lens 30 via the first light-receiving surface 321, and part of the illumination light beam can be transmitted to the second light-receiving surface 322 and transmitted into the optical lens 30 via the second light-receiving surface 322. In this embodiment, the first light-receiving surface 321 and the second light-receiving surface 322 are both planes and are arranged at an angle, so that the first light-receiving surface 321 and the second light-receiving surface 322 each have a portion opposite to each other to define the light-incoming cavity 31. In this embodiment, the angle between the first light-receiving surface 321 and the second light-receiving surface 322 is in the range of: greater than or equal to 90° and less than 180°, for example, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, etc. In other embodiments, the first light-receiving surface 321 and the second light-receiving surface 322 may be concave surfaces extending toward the interior of the optical lens 30; or, one of the first light-receiving surface 321 and the second light-receiving surface 322 is an optical plane and the other is a concave surface; or, the light-incoming surface 32 is a complete optical curved surface convex toward the interior of the optical lens 30.
[0044] In this embodiment, the sizes of the first light-receiving surface 321 and the second light-receiving surface 322 are substantially the same. In other embodiments, the angle between the first light-receiving surface 321 and the second light-receiving surface 322 can be adjusted in combination with the positional relationship between the installation reference surface 35 and the lamp beads 41 of the light source module 40, so that in such embodiments, the first light-receiving surface 321 and the second light-receiving surface 322 can have the effect of reducing the incident angle of the illumination light beam to ensure that more light beams are transmitted into the optical lens 30 and the installation wall.
[0045] Next, multiple light paths of the illumination light beam before being transmitted to the lampshade 20 in this embodiment will be described.
[0046] See also Figure 5 and Figure 6 In this embodiment, the illumination light beam includes a second light beam L2. In this embodiment, the second reflection wall 122 is disposed opposite to a portion of the light emitting surface 33. The second light beam L2 passes through at least the light inlet surface 32, the light emitting surface 33, the second reflection wall 122 and the lampshade 20 in sequence from the lamp bead 41 to the lampshade 20.
[0047] In the process of the second light beam L2 being transmitted from the light incident surface 32 to the light emitting surface 33, the second light beam L2 has at least two propagation paths. Figure 3 As an example, the second light beam L2 is transmitted to the inside of the optical lens 30 via the light-incoming surface 32, and then transmitted to the second light-emitting portion 332 of the light-emitting surface 33, and then transmitted through the second light-emitting portion 332 and transmitted to the second reflective wall 122. Figure 4 As another example, the second light beam L2 is transmitted to the inside of the optical lens 30 via the light incident surface 32, and then transmitted to the reflective surface 34, and is reflected by the reflective surface 34 and transmitted through the second light emitting portion 332 of the light emitting surface 33, and is then transmitted to the second reflective wall 122.
[0048] See also Figure 3 and Figure 4 In the process of the second light beam L2 being transmitted from the second reflective wall 122 to the lampshade 20, the second reflective wall 122 has a diffuse reflection effect on the second light beam L2, and the second light beam L2 is divided into at least two parts. As an example, part of the second light beam L2 is directly transmitted to the lampshade 20 and emitted under the reflection effect of the second reflective wall 122. As another example, part of the second light beam L2 is transmitted again to the second light emitting portion 332 of the light emitting surface 33 through the reflection effect of the second reflective wall 122, and then enters the optical lens 30 again through the second light emitting portion 332, and after the transmission inside the optical lens 30 is completed, it is transmitted through the first light emitting portion 331 or the second light emitting portion 332 and transmitted to the lampshade 20 to be emitted.
[0049] See also Figure 8 and Fig. 9 In this embodiment, there is a third light beam L3 in the illumination light beam. In this embodiment, the first reflection wall 121 is arranged opposite to the reflection surface 34. The third light beam L3 firstly transmits through the light-intake surface 32 to be transmitted into the optical lens 30, then transmits to the first light-emitting surface 33, then transmits to the second light-emitting surface 33 after total reflection from the first light-emitting surface 33, then transmits to the reflection surface 34 after total reflection from the second light-emitting surface 33, then transmits through the reflection surface 34 to be transmitted to the first reflection wall 121, then transmits to the reflection surface 34 again under the diffuse reflection of the first reflection wall 121, then transmits through the reflection surface 34 to enter the optical lens 30, finally transmits through the light-emitting surface 33 to be transmitted to the lampshade 20 and emitted. Due to the diffuse reflection of the first reflection wall 121, please refer to Figure 8 , a portion of the third light beam L3 is transmitted through the reflective surface 34 and then directly transmitted to the first light emitting portion 331 and then transmitted through the first light emitting portion 331 to be transmitted to the lampshade 20; see Fig. 9 After transmitting through the reflective surface 34 , part of the third light beam L3 is first transmitted to the second light emitting portion 332 , and then transmitted to the first light emitting portion 331 through total reflection of the second light emitting portion 332 , and then transmitted through the first light emitting portion 331 to be transmitted to the lampshade 20 .
[0050] In summary, based on the diffuse reflection effect of the first reflection wall 121 and the second reflection wall 122 and the refracting effect of the optical lens 30 in this embodiment, the optical path of the illumination light beam (including the first light beam L1, the second light beam L2 and the third light beam L3) emitted by the light source module 40 is greatly extended, which can effectively improve the divergence of the illumination light beam to achieve a soft light emission effect.
[0051] See also Fig.10 In this embodiment, the product form of the lamp 100 is a strip or strip structure, so the housing 10, the lampshade 20 and the optical lens 30 are also strip or strip structures. The housing 10 has a length direction A, a thickness direction T and a width direction W. The size of the housing 10 in the length direction A is greater than the size in the thickness direction T and greater than the size in the width direction W, that is, the length direction A of the housing 10 can be understood as the extension direction of the strip housing 10. The housing 10 has side walls 13 that are relatively spaced and connected, and the two side walls 13 define a mounting groove 11. The width direction W of the housing 10 is roughly the same as the arrangement direction of the two side walls 13, and the thickness direction T of the housing 10 is the direction of the notch of the mounting groove 11. In this embodiment, the length dimension, thickness dimension and width dimension of the lamp 100 correspond to the length direction A, thickness direction T and width direction W of the housing 10 one by one; the length dimension, thickness dimension and width dimension of the lampshade 20 correspond to the length direction A, thickness direction T and width direction W of the housing 10 one by one. As can be seen from the foregoing, the optical lens 30 and the inner wall of the mounting groove 11 effectively extend the optical path of the illumination beam, so a relatively thin lampshade 20 can be selected, that is, a lampshade 20 with a smaller thickness can be selected, so that the overall size of the lamp 100 in the thickness direction T is smaller. In this embodiment, the size range of the lamp 100 in the thickness direction T is: greater than or equal to 7.5 mm and less than or equal to 10 mm, for example, it can be 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.
[0052] It should be noted that, in addition to the strip or band structure, the optical lens 30 can also be configured as a point light source lens, and the optical path of a single or multiple light sources can be extended by using a single point light source lens.
[0053] See also Fig.10In this embodiment, the light source module 40 includes a plurality of lamp beads 41 as mentioned above and a circuit board (not shown in the figure), the circuit board is arranged in the mounting groove 11, the circuit board is generally in a strip-shaped structure and extends along the length direction of the housing 10, so as to be evenly installed in the mounting groove 11, and a plurality of first lamp beads 41 are arranged on the circuit board in sequence and at intervals along the length direction A of the housing 10, so as to be able to face the strip-shaped optical lens 30 and the lampshade 20. In this embodiment, the optical lens 30 and the inner wall of the mounting groove 11 effectively improve the divergence of the illumination beam, and there is also a large amount of illumination beam propagation in the space between two adjacent lamp beads 41, so that the distance between two adjacent lamp beads 41 can be extended, thereby reducing the arrangement of the lamp beads 41, saving costs and reducing energy consumption of the lamp 100 during normal use.
[0054] See also Fig.11 In this embodiment, the lampshade 20 includes a first light-transmitting portion 21 and a second light-transmitting portion 22 connected to each other, the first light-transmitting portion 21 is located on the side of the second light-transmitting portion 22 facing the mounting groove 11, the first light-transmitting portion 21 is opposite to the notch of the mounting groove 11 and receives the illumination light beam, and the illumination light beam is sequentially transmitted to the first light-transmitting portion 21 and the second light-transmitting portion 22. It should be understood that the second light-transmitting portion 22, the first light-transmitting portion 21 and the housing 10 are sequentially arranged along the thickness direction of the housing 10.
[0055] In this embodiment, the first light-transmitting portion 21 and the second light-transmitting portion 22 are at least partially spaced apart to define a light-mixing space 23, the axis direction of the light-mixing space 23 extending along the length direction, and the arrangement of the light-mixing space 23 enables the lamp 100 to achieve uniform light mixing. The inner wall of the light-mixing space 23 includes a side surface of the first light-transmitting portion 21 facing the second light-transmitting portion 22, and a side surface of the second light-transmitting portion 22 facing the first light-transmitting portion 21. In this embodiment, the cross-sectional profile of the light-mixing space 23 is roughly elliptical, and the arc-shaped inner wall of the light-mixing space 23 has a divergent effect on the illumination beam. In the process of the illumination beam sequentially transmitting the first light-transmitting portion 21 and the second light-transmitting portion 22, the illumination beam can be diverged again to further improve the divergence degree of the illumination beam.
[0056] See also Fig.11 In this embodiment, the first light-transmitting portion 21 is substantially in the form of a concave lens structure, so that the first light-transmitting portion 21 has a diverging effect on the illumination light beam. The second light-transmitting portion 22 may also be substantially in the form of a concave lens structure, so that the second light-transmitting portion 22 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 22 that is away from the first light-transmitting portion 21 (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.
[0057] The lamp 100 provided in this embodiment includes an optical lens 30 and a housing 10 having a first reflective wall 121. Before the illumination light beam is transmitted to the lampshade 20, it is deflected twice by the optical lens 30 and reflected once by the first reflective wall 121. The optical path of the illumination light beam is greatly extended and the illumination light beam is fully diverged, so that there are fewer light beams with higher light intensity in the illumination light beam, and the illumination light beam transmitted to the lampshade 20 is more uniform, so that the lamp 100 has a softer lighting effect. Under the setting of this embodiment, the optical lens 30 and the first reflective wall 121 have a good divergence effect on the illumination light beam. When the illumination light beam is transmitted to the lampshade 20, it is already relatively uniform. Therefore, a relatively light and thin lampshade 20 can be selected. The light and thin lampshade 20 also has a certain degree of divergence effect on the light beam, which can meet the user's requirements for uniform or soft light output of the lamp 100, and can also make the lamp 100 relatively light and thin, so that the structure of the lamp 100 is simple, smooth and tends to be flat. The simulated light output effect diagram of the lamp 100 of this embodiment is as follows: Fig.12 , wherein, after the lamp 100 is thinned as a whole, the light spot presents uniform mixed light as a whole.
