[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0030] The point light source of the utility model can enhance the beam intensity and beam range of the point light source, so that the brightness of the point light source can be suitable for scenes with high brightness requirements, and reduce the light pollution of the point light source to the surrounding environment.

[0031] In a specific embodiment of the present invention, Figures 1 to 8 As shown, the point light source includes a housing 1, a light source board 2, and a lens 3. A mounting cavity 11 is formed inside the housing 1, and an opening surface 12 is formed on the top of the housing 1. The light source board 2 is detachably connected to the inner wall surface of the mounting cavity 11. A plurality of light-emitting elements 21 are arranged at intervals on the light source board 2, and the light-emitting surfaces of the light-emitting elements 21 face the opening surface 12. The lens 3 is detachably connected to the opening surface 12, and a plurality of light-collecting portions 31 are formed on the side of the lens 3 facing the light-emitting elements 21, wherein the light-collecting portions 31 are formed with groove surfaces 312 and / or convex surfaces 311.

[0032] According to the point light source provided in this embodiment, multiple grooved surfaces 312 or multiple raised surfaces 311 are used to form a plurality of independently spaced small lens units on the side of the lens 3 facing the light-emitting element 21. When light emitted by the light-emitting element 21 is directed toward the focusing portion 31 of the lens 3, the multiple small lens units cooperate to gradually focus the light from the light-emitting element 21 onto one or more focal points, converging the light emitted by the light-emitting element 21 into a beam within a certain range. This enhances the beam intensity and range of the point light source and optimizes the focusing effect of the lens 3 on the light-emitting element 21. This makes the brightness of the point light source suitable for scenes with high brightness requirements, reduces the beam emitted by the point light source to nearby areas, and effectively reduces light pollution caused by the point light source to the surrounding environment.

[0033] Specifically, the light emitting element 21 is an LED lamp. By utilizing the characteristics of LED such as small size, light weight and rich colors, the point light source can be used as decorative lighting, and can also be arranged into various shapes such as a matrix to display various text and images, thereby expanding the application field of the point light source.

[0034] Since the LED light has a large luminous angle, its viewing angle is about 160°, so the light emitted is scattered and the brightness is low. If the LED light is required to reach a high brightness of, for example, 4000nm, at least 20 LED lights are required to emit 90% of the light to meet the requirement. In this embodiment, Figure 5 and Figure 6 As shown, by forming the lens 3 of the focusing portion 31 to focus the LED lamp, the light-emitting angle of the LED lamp can be aggregated to form a smaller beam angle such as 60°, effectively enhancing the beam intensity and beam range of the point light source. At this time, only 10 LED lamps emitting 30% of the light can meet the high brightness requirement of 4000nm, for example, effectively reducing the energy consumption of the point light source.

[0035] In this embodiment, in order to further enhance the focusing effect of the lens 3 on the light emitting element 21 , the specific structure of the lens 3 may be selected from the following exemplary structures.

[0036] The first structural form, such as Figure 3 and Figure 5 As shown, the side of the lens 3 facing away from the shell 1 forms a smooth arc surface 32, that is, the lens 3 adopts an aspheric convex lens 3, and utilizes the refraction effect of the convex lens 3 on the light of the light-emitting component 21 to focus the light of the light-emitting component 21 on the convex focus of the convex lens 3, thereby ensuring the focusing effect of the lens 3 on the light of the light-emitting component 21.

[0037] The second structural form, such as Figure 4 and Figure 6As shown in the figure, the side of the lens 3 away from the shell 1 is formed with a plurality of annular projections 33 arranged in steps, that is, the lens 3 is a Fresnel lens 3. The light rays of the light emitting element 21 are focused on the light focusing point of the Fresnel lens 3 by the refractive effect of the plurality of annular projections 33 in the Fresnel lens 3, thereby ensuring the focusing effect of the lens 3 on the light rays of the light emitting element 21.

[0038] In this embodiment, the lens 3 is detachably assembled to the opening surface 12 of the shell 1, so that the lens 3 can be conveniently replaced to apply the point light source to different demand environments. Figure 3 and Figure 4 As shown in the figure, the edge of the lens 3 is formed with an extension flange 34 which is lapped on the opening surface 12, and a fastener is arranged between the extension flange 34 and the opening surface 12.

[0039] Specifically, the fastener can be a bolt or a stud, and threaded holes are formed on the extension flange 34 and the opening surface 12, and the lens 3 is threadedly connected to the shell 1 by the bolt or the stud. In addition, the fastener can also be a buckle and a clamping hole, wherein the buckle is formed on the extension flange 34, and the clamping hole is formed on the opening surface 12, and the lens 3 is buckled and connected to the shell 1 by the buckle being buckled into the clamping hole of the shell 1. Of course, the fastener can also be other detachable connecting members, which can be selected and arranged according to the specific circumstances.

[0040] Further, when the lens 3 is assembled to the opening surface 12 of the shell 1, in order to ensure the sealing performance between the lens 3 and the shell 1, as shown in the figure, Figure 3 and Figure 4 A first sealing member 35 is arranged between the extension flange 34 and the opening surface 12 to prevent the infiltration of external moisture, dust and other pollutants into the shell 1, thereby avoiding the influence on the light focusing effect of the lens 3 on the light emitting element 21 and ensuring the use safety of the point light source.

[0041] Preferably, the first sealing member 35 is a sealing ring, and the material of the sealing ring can be an elastic material such as silica gel or rubber. The sealing ring can be directly installed on the contact surface between the extension flange 34 and the opening surface 12 by being pressed by the bolt or the buckle, so as to ensure that the sealing member can be tightly attached to the contact surface between the extension flange 34 and the opening surface 12, thereby ensuring the effective sealing of the point light source. In addition, an installation groove can be formed on the opening surface 12, and the sealing ring is installed in the installation groove, and the top of the sealing ring protrudes outward from the opening surface 12, so as to ensure that the opening surface 12 and the extension flange 34 are tightly attached, and at the same time, ensure that the sealing member will not be displaced or detached, thereby ensuring the sealing reliability.

[0042] In this embodiment, in order to ensure the installation stability of the light source plate 2 in the shell 1, as shown in the figure, Figure 3 , Figure 4 and Figure 7 As shown in the figure, the mounting cavity 11 is formed with a receiving torus 13, the light source plate 2 is overlapped on the receiving torus 13, the receiving torus 13 is formed with a connecting column 14, and the light source plate 2 is connected to the connecting column 14 through a fastener, so as to fix the light source plate 2 in the mounting cavity 11 of the shell by the receiving torus 13 and the connecting column 14, and ensure the installation stability of the light source plate 2. Meanwhile, the receiving torus 13 is hollow, and when the light source plate 2 works, the hollow structure of the receiving torus 13 can provide a heat dissipation space for the light source plate 2, so that the light source plate 2 can timely remove the heat generated by the light emitting element 21, thereby ensuring the performance of the light emitting element 21.

[0043] Specifically, the fastener is a bolt or a stud, the light source plate 2 is formed with a plurality of connecting holes coaxial with the connecting column 14, so as to threadedly fix the light source plate 2 on the receiving torus 13 through the bolt or the stud, and ensure the installation stability of the light source plate 2.

[0044] Further, a second sealing element is arranged between the receiving torus 13 and the light source plate 2, and the second sealing element is preferably sealing glue, so as to further ensure the waterproof sealing performance of the point light source by filling the sealing glue between the receiving torus 13 and the light source plate 2, and ensure the normal light emission of the light emitting element 21.

[0045] In the embodiment, as shown in the figure, Figure 8 The side of the light source plate 2 away from the light emitting element 21 is provided with a control element 22, and the control element 22 is electrically connected with the light emitting element 21. Preferably, the control element 22 is a control chip, and the light emitting brightness and color change of the light emitting element 21 can be adjusted by the control element 22, so that the point light source can emit light lines of various colors when working, thereby improving the flexibility of the point light source when used and greatly enriching the visual effect.

[0046] Correspondingly, as shown in the figure, Figure 9 The utility model also provides a point light source lamp strip system, the point light source lamp strip system includes a controller and a plurality of point light sources as any one of the above embodiments, and the controller is electrically connected with each point light source through the wire 4. The point light source lamp strip system can enhance the overall light beam intensity and light beam range by the lens 3 in the plurality of point light sources, so that the point light source lamp strip system can be applied to scenes with higher brightness requirements. In addition, the point light source lamp strip system also has all the beneficial effects of the point light source, which will not be repeated here.

[0047] Among them, in order to connect the plurality of point light sources in sequence to form a point light source lamp strip network, as shown in the figure, Figure 9As shown, the side wall of the housing 1 is formed with at least two plug holes 15, which are connected to the installation cavity 11. The two ends of the wire 4 are respectively inserted into the two plug holes 15 facing each other, so that any two adjacent point light sources can be connected through the wire 4. In actual use, multiple point light sources can be connected in series through the wires 4 to form a long strip of point light source light strips. Subsequently, multiple long strips of point light source light strips are connected in series using the wires 4 again to form a point light source light strip network, effectively improving the adaptability of the point light source light strip system to various special scenes.

[0048] It should be noted that the point light source light strip system can be spliced ​​according to actual needs, wherein the length of the wire 4 can be freely selected, and light strip systems with different point spacings can be prepared accordingly to meet the user's usage needs.

[0049] It should be further noted that the side wall of the housing 1 of the point light source may be formed with two, three, or four plug holes 15 to accommodate the wiring requirements of the wires 4. Furthermore, the side wall of the housing 1 of the point light source may also directly form four plug holes 15, with each plug hole 15 having a flip cover at its opening. The flip cover of the corresponding plug hole 15 can then be opened as needed to insert the wire 4 and connect to the light-emitting element 21, effectively reducing the number of different specifications of the point light sources in a single point light source strip network.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
