[0030] In other embodiments, the base plate 100 may be made of a light-transmitting material, such as glass, polycarbonate, etc.

[0031] In the above-mentioned point light source base 10, the shell 400 is connected to the bottom plate 100 and the connecting seat 200 respectively by snap-fitting. The point light source base 10 has a simple structure, which reduces its own weight, and the connection method is simple, which makes the disassembly and assembly of the point light source particularly convenient and improves the disassembly and assembly efficiency.

[0032] Continue to see Figure 2 In one embodiment, there are two connection bases 200, and the two connection bases 200 are fixed to opposite ends of the bottom plate 100. A buckle 110 is provided on the bottom plate 100, and the connection base 200 and the buckle 110 are arranged at intervals. There are four buckles 110, two of which are arranged at intervals on one side of the bottom plate 100, and two of which are also arranged at intervals on the other side. The buckles 110 on both sides are arranged symmetrically. The connection base 200 and the plurality of buckles 110 form a first installation position, and the mounting plate 300 is received in the first installation position and connected to the connection base 200. A slot 410 cooperating with the buckle 110 is provided on the side wall of the housing 400, and the buckle 110 is engaged with the slot 410 to realize the connection between the housing 400 and the bottom plate 100.

[0033] It should be noted that the number of the buckles 110 and the slots 410 is not limited to four. In some embodiments, the number of the buckles 110 and the slots 410 that cooperate with them can also be 2 or more. As long as the buckles 110 and the slots 410 cooperate with each other, the shell 400 and the base plate 100 can be stably buckled together.

[0034] The card slot 410 is formed by the outer surface of the housing 400 being recessed toward the center of the housing 400, and the number of the card slots 410 corresponds to the number of the buckles 110. The card slot 410 extends to the lower end of the housing 400 in the vertical direction, and the upper end portion of the bottom wall of the card slot 410 continues to be recessed toward the center of the housing 400 to form a card hole 411. The buckle 110 is vertically arranged on the bottom plate 100, and the upper end of the buckle 110 protrudes a certain length in the radial direction to form a hook-shaped structure. During the connection process between the housing 400 and the bottom plate 100, the buckle 110 is accommodated in the card slot 410, and the hook-shaped structure of the buckle 110 is engaged with the card hole 411.

[0035] See also Figure 3 In one embodiment, the connection seat 200 includes a bearing portion 210 and a connecting portion 220. The bearing portion 210 is fixed to the bottom plate 100, and the connecting portion 220 is fixed to the side wall of the bearing portion 210. A relief groove 230 is provided on the side of the bearing portion 210 that is farther from the connecting portion 220, and a step portion 240 is provided on the inner wall of the relief groove 230. The relief groove 230 and the step portion 240 constitute a first mounting position, and one end of the mounting plate 300 can be placed on the step portion 240 to be supported, and screws can be used to further fix the mounting plate 300 to the step portion 240.

[0036] In one embodiment, the connection base 200 is provided with a first positioning block 250. Figure 2 The housing 400 includes a second positioning block 420, and the housing 400 is connected to the connection seat 200 by engaging with the second positioning block 420 through the first positioning block 250. Two first positioning blocks 250 are provided, and the two first positioning blocks 250 are respectively arranged at the two ends of the connection seat 200 and are symmetrically arranged. The upper end of the first positioning block 250 is radially extended with a first protrusion 251, so that one end of the first positioning block 250 is in a hook shape, and the left side of the first protrusion 251 is set as an inclined surface. The two ends of the second positioning block 420 are extended with second protrusions 421, and the side of the second protrusion 421 opposite to the first protrusion 251 is set as an inclined surface. When the housing 400 is connected to the connection seat 200, the housing 400 moves downward, and the inclined surface of the second positioning block 420 will move downward along the inclined surface of the first positioning block 250, so that the upper end surface of the second protrusion 421 is engaged with the lower end surface of the first protrusion 251, thereby realizing the connection between the housing 400 and the connection seat 200. It should be noted that the first protrusion 251 has a certain elasticity. When the housing 400 and the connecting base 200 are disassembled, the first protrusions 251 on both sides are simultaneously bent in a direction away from the second positioning block 420 to release the second protrusion 421 .

[0037] In one embodiment, when the buckle 110 cooperates with the slot 410, the first positioning block 250 and the second positioning block 420 are engaged, so that the housing 400 is simultaneously engaged with the bottom plate 100 and the connecting seat 200, which can improve the installation accuracy between the housing 400, the bottom plate 100 and the connecting seat 200, and at the same time enhance the stability of the overall connection. By connecting with the buckle 110, a large number of screws used in screw connection can be omitted, thereby simplifying the structure of the entire point light source base 10, reducing the weight of the point light source base 10, and saving the working time consumed by installing the screws, thereby improving the disassembly and assembly efficiency of the point light source base 10 and reducing the labor intensity of disassembly and assembly.

[0038] See also Figure 4 and Figure 5 In one embodiment, a limited space 500 is formed between the bearing portion 210 and the mounting plate 300. The housing 400 further includes a third positioning block 430, which is accommodated in the limited space 500 to limit the housing 400 and prevent the housing 400 from moving.

[0039] Specifically, the mounting plate 300 includes an abutting portion 310 and a main body 320. The abutting portion 310 is formed by extending radially along the main body 320, and the abutting portion 310 is received in the avoidance groove 230, and the step portion 240 is arranged on the inner wall of the avoidance groove 230. The abutting portion 310 is received in the avoidance groove 230, and the bottom surface of the abutting portion 310 is placed on the step portion 240, and the side surface of the abutting portion 310 abuts against the inner wall of the avoidance groove 230. The bearing portion 210 and the main body 320 are arranged at intervals, and the bearing portion 210, the abutting portion 310 and the main body 320 together enclose a limiting space 500. A cavity 440 is formed inside the housing 400. When the housing 400 is loaded on the bottom plate 100, the cavity 440 will accommodate the mounting plate 300 and the light emitter 11 on the mounting plate 300 to avoid interference. The third positioning block 430 is fixed on the inner wall of the cavity 440. The third positioning block 430 is arranged opposite to the limiting space 500. When the shell 400 is installed on the base plate 100, the third positioning block 430 is inserted into the limiting space 500. The side wall of the third positioning block 430 will abut against the side wall of the limiting space 500 to cooperate with the positioning to improve the installation accuracy of the shell 400, avoid relative movement between the shell 400 and the base plate 100, and ensure the stability of the connection.

[0040] See also Figure 2 In one embodiment, the connection base 200 is recessed to form a first recessed groove 260, and the housing 400 is recessed to form a second recessed groove 450 corresponding to the first recessed groove 260. Figure 1 When the housing 400 is connected to the connection base 200, the first sinking groove 260 and the second sinking groove 450 together form a wire hole 600 for the transmission line to pass through.

[0041] Since the light-emitting body 11 is connected with transmission lines such as signal lines and power lines, the signal lines are used to transmit signals, and the power lines are used to transmit current. Both the signal lines and the power lines are connected to the light-emitting body 11 located on the mounting plate 300, and the signal lines and the power lines are passed through the wire holes 600 and exposed outside the entire point light source base 10, so as to be connected with the signal lines and power lines located on other point light source bases 10, so as to realize the exchange of current and signals between the light-emitting bodies 11 in different point light source bases 10. In this embodiment, the number of the first sink grooves 260 is five, and the number of the first and second sink grooves 450 is also five, so that five wire holes 600 are formed between the housing 400 and the connecting base 200. For example, the five wire holes 600 are arranged in a straight line, and the three wire holes 600 located in the middle can be used to pass the signal lines, and the two wire holes 600 located at the edge can be used to pass the power lines.

[0042] The present invention also provides a point light source, which includes a light emitting body 11 and the above-mentioned point light source base 10, and the light emitting body 11 is connected to the mounting plate 300. Since the housing 400, the connecting seat 200 and the bottom plate 100 of the point light source base 10 are connected by the buckle 110, the disassembly efficiency of the entire point light source can be improved and the weight can be reduced.

[0043] The present invention also provides a display screen, which includes the above-mentioned point light sources, wherein the number of the point light sources is multiple, and the multiple point light sources are installed on a functional module of the display screen. The lighting effect or image display of the entire display screen is achieved by controlling the lighting or extinguishing of the point light sources.

[0044] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
