[0041] To further understand the purpose, structure, features, and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.

[0042] In the description and claims of the present specification, certain terms are used to refer to specific elements. Those of ordinary skill in the art should understand that manufacturers may use different terms to refer to the same element. The present specification and claims do not use the difference in names as a way to distinguish elements, but use the difference in functions of elements as the criterion for distinction. The term "including" mentioned throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to".

[0043] Please refer to Figure 1 and Figure 2 , Figure 1 which shows an exploded structural schematic diagram of the screen hanging lamp in an embodiment of the present utility model, Figure 2The rear view schematic diagram of the screen hanging lamp according to an embodiment of the present utility model is shown. The screen hanging lamp includes a lamp body 100, and the lamp body 100 is used to be installed on a display. In this embodiment, the first housing 10 of the lamp body 100 includes a support portion 11 and an adjustment portion 12. The adjustment portion 12 is, for example, in a plate shape and has opposite connection ends 12s and free ends 12r in its extending direction. The connection end 12s is pivotally connected to the support portion 11. Please refer to Figure 3 , which shows the side view schematic diagram of the screen hanging lamp clamped on the display in an embodiment of the present utility model. By the support portion 11 being non-adjustably abutted against the upper surface of the display 200, and the user can adjust the rotation of the free end 12r according to the shape of the display 200 (such as the thickness of the housing of the display 200, etc.). At this time, an angle adapted to the shape of the display 200 is formed between the support portion 11 and the adjustment portion 12, so that the free end 12r can abut against the housing behind the display 200. Further, the clamping force can be provided to the display 200 by virtue of the weight of the adjustment portion 12 itself, so that the display 200 is clamped between the support portion 11 and the adjustment portion 12. In a preferred embodiment, an elastic element (not shown in the figure) is provided at the connection between the connection end 12s of the adjustment portion 12 and the support portion 11. When the adjustment portion 12 and the support portion 11 are relatively rotated, the elastic element deforms and stores elastic potential energy. When the adjustment portion 12 and the support portion 11 are released, the elastic element releases the elastic potential energy and resets. The elastic element is, for example, a torsion spring, but the actual application is not limited thereto.

[0044] In this embodiment, as Figure 3 shown, the support portion 11 is further provided with a limiting block 111. The limiting block 111 and the connection end 12s are respectively located at opposite ends of the support portion 11. The limiting block 111 is used to abut against the edge of the housing in front of the display 200. For example, the limiting block 111 can be a convex block 111 extending from top to bottom. In some other embodiments, the first housing 10 can also be in other styles that can be installed on the display, but the actual application is not limited thereto.

[0045] It should be noted that the front of the display 200 is the direction in which the display 200 faces the user, and this front is usually the display screen of the display 200; the rear of the display 200 is the direction corresponding to the back shell of the display 200, which is usually close to the wall. The directions such as up, down, left, and right correspond to the habitual directions of objects relative to the user in the actual application scenario of the display 200 by the user. The vocabulary indicating the orientation mentioned in this article is the same as the above situation, so it will not be elaborated here.

[0046] Further, the screen hanging lamp further includes a first light-emitting member 13 and a second light-emitting member 14. The first light-emitting member 13 is mounted on the first housing 10. For example, the first light-emitting member 13 can be clamped to the support portion 11. In some embodiments, the first light-emitting member 13 is a strip-shaped lamp tube, and the support portion 11 has an annular connecting member sleeved on the outer peripheral portion of the first light-emitting member 13, so that the first light-emitting member 13 can rotate in the annular connecting member; in other embodiments, the first light-emitting member 13 can also be fixedly connected to the support portion 11; however, the actual application is not limited thereto. The second light-emitting member 14 is detachably connected to the first housing 10. Specifically, the lamp body 100 in this embodiment further includes a first connector 11c. The support portion 11 has a first opening for arranging and exposing the first connector 11c. The second light-emitting member 14 has a second housing 14h and a second connector 14c. The second connector 14c protrudes from the second housing 14h. By detachably connecting the second connector 14c to the first connector 11c, the second light-emitting member 14 is mounted on the support portion 11.

[0047] Based on the above, when the screen hanging lamp is mounted on the display 200, the first light-emitting member 13 emits light toward the first area s1 in front of the display 200, and the second light-emitting member 14 emits light toward the second area s2 behind the display 200. In some embodiments, the second area s2 at least includes an area relatively above the display 200 (such as Figure 3 the part above the dotted line in the figure). In other embodiments, the second light-emitting member 14 can also emit light toward the rear and above of the display 200 (the corresponding area on the upper surface of the display 200) (not shown in the figure), however, the actual application is not limited thereto. In this way, the second light-emitting member 14 can make up for the light in the dark area behind the display 200, and avoid a large difference between the sum of the brightness of the display 200 and the brightness of the first light-emitting member 13 and the ambient brightness behind the display 200, resulting in visual fatigue of the user. Taking the embodiment in which the first housing 10 includes the support portion 11 and the adjustment portion 12 as an example, it can be understood that when the screen hanging lamp is clamped to the display 200, the support portion 11 directly abuts against the edge of the housing in front of the display 200, so that the position of the support portion 11 relative to the display 200 is fixed; and after the second light-emitting member 14 is mounted on the support portion 11, the position of the second light-emitting member 14 relative to the support portion 11 is fixed, so that the position of the second light-emitting member 14 is relatively fixed relative to the display 200, that is to say, the illumination direction of the second light-emitting member 14 relative to the display 200 can also be fixed. In this way, the light pattern of the light projected by the second light-emitting member 14 toward the rear of the display 200 has a higher directivity to more effectively make up for the ambient light brightness.

[0048] Preferably, the second housing 14h of the second light-emitting member 14 has a positioning groove 142 for cooperating with the support portion 11 to guide the second connector 14c to be aligned with the first connector 11c. In this embodiment, as Figure 1 or Figure 2 shown, the second housing 14h has a first portion extending in the horizontal direction, and a second portion and a third portion extending in the vertical direction. Ramps are formed at the connection between the first portion and the second portion, and at the connection between the first portion and the third portion, that is, the positioning groove 142, for guiding the second connector 14c located on the lower surface of the first portion to be aligned with the first connector 11c located on the upper surface of the support portion 11. However, the shape of the second housing 14h and the specific form of the positioning groove 142 are not limited thereto. In some embodiments, the second housing 14h further has a relief groove 141. In this embodiment, the relief groove 141 is provided outside the positioning groove 142. However, the actual application is not limited thereto. After the second connector 14c is aligned with the first connector 11c, the relief groove 141 is used to make room for the support portion 11 and the adjustment portion 12. In this way, while not affecting the user's adjustment of the adjustment portion 12, the appearance of the second light-emitting member 14 is made consistent with the appearances of the support portion 11 and the adjustment portion 12 as a whole, making the screen hanging lamp more beautiful. In this embodiment, as Figure 1 and Figure 2 shown, a groove is formed in the middle of the second housing 14h to form a "U" shape. The second connector 14c is disposed at the groove corresponding to the middle of the second housing 14h, which means that the groove in the middle is the relief groove 141. In other words, the second portion and the third portion of the second housing 14h described above are respectively connected to opposite ends of the first portion, forming a "U" shape and forming the relief groove 141. Specifically, as Figure 1 shown, the user can hold the second light-emitting member 14 and install the second light-emitting member 14 on the support portion 11 with the relief groove 141 facing downwards. At this time, the second connector 14c is located on the lower surface of the first portion and is connected to the first connector 11c located on the upper surface of the support portion 11. The second portion and the third portion then extend towards the adjustment portion 12. In some embodiments, as Figure 2 shown, the length dimension of the first portion in the left-right direction is greater than the maximum length dimension of the adjustment portion 12 in the left-right direction, which means that the second portion and the third portion can extend downward for a longer length dimension, so that the connecting end portion 12s and the free end portion 12r of the adjustment portion 12 can be accommodated in the relief groove 141 together, and the free end portion 12r can move in the relief groove 141; In other embodiments, as Figure 4As shown, in the left - right direction, the length dimension of the free end portion 12r of the adjusting portion 12 is greater than the length dimension of the connecting end portion 12s, and the length dimension of this first part in the left - right direction is less than the maximum length dimension of the adjusting portion 12 in the left - right direction. In other words, in the left - right direction, the length dimension of this first part is greater than the length dimension of the free end portion 12r and less than the length dimension of the connecting end portion 12s. Only the connecting end portion 12s is received in the relief groove 141 for rotation, and the free end portion 12r is located outside the relief groove 141. In some other embodiments, the adjusting portion 12 can also be arranged away from the installation position of the second housing 14h. That is to say, the rotation of the adjusting portion 12 will not interfere with the second housing 14h. At this time, the second housing 14h can also be designed in a shape without the relief groove 141. However, the actual application is not limited to this.

[0049] In some preferred embodiments, one of the first connector 11c and the second connector 14c is a plug (such as a plug in the form of Type-C, a gold finger, etc.), and the other is a socket corresponding to the plug, so that the first connector 11c is electrically connected to the second connector 14c; in this embodiment, the first connector 11c and the second connector 14c are pogo pin connectors. Among them, the pogo pin connector generally includes basic components such as an insertion slot, a needle head, a spring, and a needle tube. For example, the needle head, the spring, and the needle tube are located on the side of the second connector 14c. The needle head and the spring are arranged inside the needle tube. The head of the needle head extends out from the opening of the needle tube. The tail of the needle head (opposite to the position of the head of the needle head) abuts against the spring. The insertion slot is located on the side of the first connector 11c. After the head of the needle head contacts the insertion slot, the needle head is pushed to move inside the needle tube, and the spring is compressed synchronously. By the resilience of the spring, the needle head tightly abuts against the insertion slot, so that the first connector 11c is coupled to the second connector 14c. Among them, both the needle head and the insertion slot are made of metal materials, such as gold-plated or nickel-plated materials. That is to say, in this embodiment, the first connector 11c and the second connector 14c are electrical connectors, and electrical signals are transmitted through the tight abutment between the needle head and the insertion slot. For example, the screen hanging lamp includes a main control circuit board and an external power supply (not shown in the figure). The main control circuit board and the external power supply can be arranged in the first housing 10. A control unit (Microcontroller Unit, MCU) can be provided on the main control circuit board, and the main control circuit board is coupled to the external power supply. The first light-emitting element 13 and the first connector 11c can be respectively coupled to the control unit. Through the electrical connection between the second connector 14c and the first connector 11c, the second light-emitting element 14 is connected to the circuit; and, the first light-emitting element 13 and the second light-emitting element 14 can also be respectively controlled by the control unit. For example, control signals can be sent through the control unit to adjust the color temperature, brightness, etc. of the first light-emitting element 13 or the second light-emitting element 14. In some embodiments, the screen hanging lamp further includes an input unit coupled to the control unit, such as a remote control based on infrared or Bluetooth transmission signals, or adjustment buttons, levers, etc. provided on the first housing 10 or the second housing 14h. The user can adjust the light brightness of the second light-emitting element 14 by operating the input unit; in other embodiments, the screen hanging lamp can further include an ambient light detection unit (not shown in the figure, such as can be arranged on the main control circuit board) coupled to the control unit. By the ambient light detection unit, the ambient light brightness around the display 200 is obtained. The control unit automatically adjusts the light brightness of the second light-emitting element 14 based on the light brightness of the first light-emitting element 13 and / or the brightness of the ambient light; however, the actual use is not limited to this.

[0050] Based on the above, the first housing 10 further has a first magnetic member (not shown in the figure), and the second housing 14h further has a second magnetic member (not shown in the figure). The positions of the first magnetic member and the second magnetic member are opposite to each other and are respectively adjacent to the first connector 11c and the second connector 14c, so that the second light-emitting member 14 and the support portion 11 can be fixedly connected under the action of the magnetic attraction force between the first magnetic member and the second magnetic member. This magnetic attraction force can ensure that the connection between the second light-emitting member 14 and the support portion 11 is closely fitted, thereby ensuring the reliability of the electrical connection between the spring pin connector and the insertion slot. In other words, by the mutual magnetic attraction of the first magnetic member and the second magnetic member, the coupling of the first connector 11c and the second connector 14c can be guided. In some other embodiments, the first housing 10 and the second housing 14h may respectively include corresponding buckles and slots as mechanical connectors to assist in the electrical connection between the second connector 14c and the first connector 11c. In still some other embodiments, the second light-emitting member 14 may have an independent external power supply and a main control circuit board, and the first connector 11c and the second connector 14c are only mechanical connectors that cooperate with each other, but the actual application is not limited to this.

[0051] In a preferred embodiment, as Figure 1 or Figure 4 shown, the lamp body 100 has a plurality of first connectors 11c, and the second connector 14c on the second light-emitting member 14 is alternatively connected to one of the plurality of first connectors 11c, so that the user can select multiple different positions on the lamp body 100 to install the second light-emitting member 14. In other words, the position of the second light-emitting member 14 relative to the lamp body 100 is replaceable. After the second connector 14c is connected to one of the first connectors 11c, the second light-emitting member 14 is fixed in the illumination direction relative to the display 200 based on the position of the one first connector 11c. In this way, the user can replace the position of the second light-emitting member 14 according to the actual application requirements, so that the compensation effect of the second light-emitting member 14 on the ambient light has stronger universality. Preferably, the plurality of first connectors 11c are distributed along the front-back direction of the display 200 on the support portion 11. That is to say, the above-mentioned replacement of the position of the second light-emitting member 14 specifically refers to adjusting the front-back position of the second light-emitting member 14 relative to the display 200. For example, the distance between the second light-emitting member 14 and the wall surface behind the display 200 can be adjusted accordingly, so that the illumination effect of the second light-emitting member 14 can be adjusted to the best.

[0052] In some other embodiments, the second light-emitting member 14 is non-removably mounted on the first housing 10. The same structures as those in the previous embodiments will not be described again. The difference is that, as Figure 5As shown, the second light-emitting component 14 is fixedly arranged at the rotating shaft where the support part 11 is connected to the adjusting part 12, and its position relative to the support part 11 is fixed. For example, the second housing 14h of the second light-emitting component 14 is integrally formed with the support part 11; alternatively, the second housing 14h is fixedly connected to the support part 11 by means of buckles, adhesives, etc. In addition, the second light-emitting component 14 can also be coupled to the main control circuit board in the first housing 10 through an internal cable, but the actual application is not limited to this. Among them, the second light-emitting component 14 is arranged at the rotating shaft where the support part 11 is connected to the adjusting part 12, which can also maximize the avoidance of the lamp body 100 blocking the light emitted by the second light-emitting component 14, making the light pattern of the light projected by the second light-emitting component 14 to the rear of the display 200 more complete.

[0053] In summary, the screen hanging lamp provided by the present utility model includes a lamp body, a first light-emitting component, and a second light-emitting component. The lamp body is used for mounting on a display, and the lamp body includes a first housing and a first connector. The first housing has a first opening for setting and exposing the first connector. The first light-emitting component is mounted on the first housing. The second light-emitting component has a second housing and a second connector. The second connector protrudes from the second housing, and the second connector is detachably connected to the first connector. Among them, the first light-emitting component emits light towards a first area in front of the display, and the second light-emitting component emits light towards a second area behind the display and the illumination direction of the second light-emitting component is fixed relative to the display.
