Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Figure 1 A schematic diagram of the structure of a strip light fixture according to an embodiment of this application is shown. Figure 2 An exploded structural diagram of a strip light fixture according to an embodiment of this application is shown.

[0023] See Figure 1 and Figure 2 The first aspect of this application provides a strip lamp, including: a strip lens 10; two connecting long sides 20, which are respectively formed integrally with the strip lens 10 along the length direction of the strip lens 10, forming a mounting cavity 30 with the strip lens 10; and a lamp panel 40, including a circuit board 42 and a plurality of light sources 41, wherein the circuit board 42 is connected to the connecting long sides 20 to enclose the mounting cavity 30, and the light sources 41 are distributed on the first surface of the circuit board 42 and located within the mounting cavity 30, with the light sources 41 facing the strip lens 10.

[0024] The strip lights provided in this application can be used as directional lighting for small spaces such as cabinets, display cases, glass cabinets, and wall cabinets, highlighting the details of the exhibits through lighting arrangements adapted to the exhibits.

[0025] Based on the lighting requirements corresponding to the display case and the target exhibits, the lens type of the strip lens 10 can be adapted and selected. The lens type of the strip lens 10 can include, but is not limited to, Fresnel lenses, condenser lenses, anti-glare lenses, total internal reflection lenses, polarizing lenses, etc. In one implementation scenario, the lighting requirement is to adopt a small-angle polarization design, and the corresponding lens type can be a total internal reflection polarizing lens.

[0026] The two connecting long sides 20 are integrally formed with the strip lens 10, and are respectively disposed on both sides of the strip lens 10 along its length direction, and are symmetrically arranged relative to the length direction of the strip lens 10. Furthermore, one end of the connecting long side 20 is connected to the strip lens 10, and the other end extends away from the light-emitting surface 11 of the strip lens 10, forming a U-shaped mounting cavity 30 with the strip lens 10. The total reflection surface 12 and the light-incident surface 13 of the strip lens 10 are both located within the mounting cavity 30.

[0027] The lamp panel 40 includes a circuit board 42 and multiple light sources 41. The shape of the circuit board 42 is adapted to the shape of the mounting cavity 30, allowing the circuit board 42 to be embedded within the mounting cavity 30 and connected to the connecting long side 20 to enclose the mounting cavity 30. It should be noted that the circuit board 42 is provided with a power-taking component 421 to obtain power; the power-taking component 421 can be any type of power-taking terminal, power-taking spring, power-taking wire, etc. The light sources 41 are equidistantly distributed along the length of the circuit board 42 on the first surface of the circuit board 42 and located within the mounting cavity 30, with the light sources 41 facing the light-incident surface 13 of the strip lens 10.

[0028] The strip lamp provided in this application embodiment has a simple structure, improves assembly effect, reduces product cost, and reduces the matching error between the lamp panel 40, the strip lens 10 and the lamp holder by integrally forming the two connecting long sides 20 and the lamp panel 40. This makes the relative position accuracy between the light source 41 of the lamp panel 40 and the strip lens 10 more accurate, which helps to achieve a higher precision small-angle polarization design.

[0029] In one possible implementation, a support post 21 is formed on one surface of the connecting long side 20 located in the mounting cavity 30, and the support post 21 abuts against the first surface of the circuit board 42.

[0030] There are multiple support pillars 21, which are equidistantly arranged on one surface of the connecting long side 20 located in the mounting cavity 30, so that the first surface of the circuit board 42 can abut against it. Moreover, the support pillars 21 on both connecting long sides 20 are symmetrically arranged to ensure that the circuit board 42 is installed stably.

[0031] In one possible implementation, a cold-stamped protrusion 22 is formed at a position corresponding to the second surface of the circuit board 42 connecting the long side 20. The cold-stamped protrusion 22 abuts against the second surface of the circuit board 42, and the position of the cold-stamped protrusion 22 corresponds to that of the support post 21.

[0032] In actual production, after the circuit board 42 is abutted against the support post 21, in order to prevent the circuit board 42 from deviating from the support post 21 and falling out of the mounting cavity 30, cold stamping can be performed on the surface of the connecting long side 20. This causes the cold stamping part of the connecting long side 20 to deform and form a cold stamping protrusion 22 that protrudes towards the circuit board 42. The cold stamping protrusion 22 and the support post 21 are located at the same cross-sectional position, thereby ensuring that the circuit board 42 can be clamped and preventing the circuit board 42 from being displaced relative to the support post 21.

[0033] By using cold stamping, the connection between the lamp panel 40 and the lens can be achieved without the need for other fasteners such as screws or snap-fit ​​structures. This makes production convenient, provides greater strength, and ensures the service life of the lamp.

[0034] In one possible implementation, a snap-fit ​​element 23 is formed on the surface of the connecting long side 20 facing away from the mounting position. The snap-fit ​​element 23 can be snap-fit ​​protrusions equidistantly arranged along the length direction of the connecting long side 20. The shape of the snap-fit ​​protrusions is adapted to the shape of the target mounting position, thereby facilitating the installation of the strip light fixture without the need for additional components.

[0035] Figure 3 An exploded structural diagram of a lighting track system according to an embodiment of this application is shown. Figure 4 A cross-sectional structural schematic diagram of a lighting track system according to an embodiment of this application is shown. Figure 5 A schematic diagram of the overall structure of a lighting track system according to an embodiment of this application is shown.

[0036] See Figure 3 , Figure 4 and Figure 5 In one possible implementation, at least one connecting short side 50 is located along one side of the width direction of the strip lens 10 and is integrally formed with the strip lens 10.

[0037] Depending on the installation environment, the strip light fixture provided in this embodiment can be located on one side of the strip lens 10 in the width direction, and can have one connecting short side 50, two connecting short sides 50, or no connecting short sides 50. When the strip light fixture is an independent fixture, it can have two connecting short sides 50. By designing the connecting short sides 50, the applicability and application scenarios of the target light fixture can be broadened.

[0038] In one possible implementation, a snap-fit ​​51 is formed on the connecting short side 50, and a snap-fit ​​block 422 symmetrical to the snap-fit ​​is formed on the circuit board 42. The snap-fit ​​51 can be formed at a non-central position of the connecting short side 50. This arrangement can prevent mistaken installation and facilitate the installation of the light panel 40.

[0039] A second aspect of this application provides a lighting track system, comprising: a power supply track 60; and at least one strip lamp as described in the first aspect of this application, the strip lamp being embedded within the power supply track 60.

[0040] The power supply track 60 includes a track body 61, which forms a connecting cavity for embedding the strip lamp. A power supply conductor 62 is disposed at the bottom of the connecting cavity. When the strip lamp is inserted into the connecting cavity, the power supply component 421 on the lamp panel 40 of the strip lamp contacts the power supply conductor 62 to draw power, thereby realizing the illumination of the strip lamp.

[0041] In one possible implementation, when there are multiple strip lights, the strip lights include: a first strip light 100 having at least one connecting short side 50; a second strip light 200 having an opening in the width direction of the strip lens 10; and the end of the first strip light 100 without the connecting short side 50 being spliced ​​with the second strip light 200.

[0042] Specifically, if the strip lights are interconnected, and the first strip light 100 is located at one end of all other strip lights, the first strip light 100 can be equipped with a connecting short side 50 on the corresponding side to achieve closure of that end. If the strip lights are interconnected, and the second strip light 200 is located between two other strip lights, then the target strip light 200 does not need to be equipped with a connecting short side 50, achieving seamless connection between the strip lights and making the light output more uniform.

[0043] In one possible implementation, the length of at least one strip lamp is different from the length of the other strip lamps.

[0044] The strip lens 10 and the two connecting long sides 20 of the strip light fixture provided in this application embodiment can be formed by extrusion or injection molding in one step, and the structure is simple. Therefore, when installing for a specific target scene, the length of the strip lens 10 and the two connecting long sides 20 can be cut to adapt to the target scene. Therefore, when installing the strip light fixture to the power supply track 60, the last strip light fixture installed, or at least one strip light fixture installed in the middle, can be cut to adapt to the power supply track 60 of any length.

[0045] It should be understood that the cut strip light fixture can be connected to a light panel 40 of the corresponding length and equipped with a power supply component 421, or connected to an adjacent light panel 40 for power supply, so as to achieve the illumination of the cut strip light fixture.

[0046] A third aspect of this application provides a display cabinet equipped with strip lights as described in the first aspect of this application or a lighting track system as described in the second aspect of this application.
