Description

Technical Field

[0001] The utility model relates to the technical field of LED light sources, in particular to an LED matrix light source. Background Art

[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire.

[0003] For example, a Chinese utility model patent (CN203325904U) discloses a matrix-type LED light source module, which states: "A transparent substrate is used to replace the aluminum substrate in the existing LED light source module to increase the astigmatism range of the LED chip light. The astigmatism range can reach 180°, and only fluorescent strips are coated on the LED chip, which greatly reduces the manufacturing cost; different matrix columns are designed to have different color temperatures, and in conjunction with the drive circuit, one matrix column can be lit up individually or multiple matrix columns can be lit up at the same time, that is, one module can achieve multiple color temperatures."

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] Embodiment 1:

[0032] Please refer to Figure 1-4, an LED matrix light source, comprising an LED lamp body 1, wherein a triangular card slot 2 is symmetrically provided inside the upper end of the LED lamp body 1, a mounting seat 3 is fixed at the center of the upper end of the LED lamp body 1, a rectangular slot 11 and a slide slot 12 are respectively provided inside the lower end of the LED lamp body 1, the mounting seat 3 is slidably connected with the slide slot 12, a bidirectional screw 14 and a second guide column 15 are respectively provided inside the rectangular slot 11, the bidirectional screw 14 is rotatably connected with the LED lamp body 1, and the second guide column 15 is fixed with the LED lamp body 1, when a plurality of LED lamp bodies 1 are assembled with each other and fit each other, after the mounting seat 3 slides into the slide slot 12, in order to facilitate the rotation of the bidirectional screw 14, a rack 4 is fixed inside the mounting seat 3, a flat gear 16 is fixed at the center of the outer side of the bidirectional screw 14, and the flat gear 16 is meshed with the rack 4;

[0033] The outer side of the bidirectional screw 14 is symmetrically threadedly connected with a derivation card seat 17, and the two derivation card seats 17 are both slidably connected with the second guide column 15, so that when the bidirectional screw 14 rotates, it can drive the two derivation card seats 17 to move closer to or away from each other through the guidance of the second guide column 15. When the two derivation card seats 17 move away from each other and enter the inner side of the triangular card slot 2 respectively, in order to facilitate the limited fixation of the two derivation card seats 17, an extension plate 5 is fixed to the outer side of the lower end of the LED lamp body 1, and two pull rods 6 are slidably connected to the lower end of the extension plate 5. A first spring 7 is fixed between the outer side of one end of each pull rod 6 and the extension plate 5, and the other end of the pull rod 6 passes through the LED lamp body 1 and the derivation card seat 17 respectively and is slidably connected to the LED lamp body 1 and the derivation card seat 17;

[0034] In order to facilitate pulling the two pull rods 6 with one hand at the same time and further simplify the installation operation, a connecting plate 8 is fixed between the two pull rods 6, and the connecting plate 8 is located at the end of the extension plate 5 away from the LED lamp body 1. When the two pull rods 6 penetrate the LED lamp body 1 and slide into the two derivation sockets 17 respectively, the position of the derivation sockets 17 is limited and fixed. Then, when the derivation sockets 17 are limited and fixed on the inner side of the triangular slot 2, the assembly between the two LED lamp bodies 1 is realized. At this time, in order to further limit the pulling of the connecting plate 8, thereby making the installation between the two LED lamp bodies 1 more stable, a support shaft 9 is also fixed at the end of the extension plate 5 away from the LED lamp body 1, and a drooping limit block 10 is rotatably connected to the outer side of the support shaft 9. The drooping limit block 10 is located at the end of the connecting plate 8 away from the extension plate 5, and the lower end of the drooping limit block 10 is in contact with the connecting plate 8.

[0035] Embodiment 2:

[0036] The LED matrix light source provided in Example 1 is further optimized, specifically, as follows: Figure 3As shown, when the carrying seat 3 slides into the inner side of the slide groove 12, in order to guide the sliding of the carrying seat 3 and prevent it from being easily offset, two first guide pillars 13 are arranged inside the slide groove 12, and the two first guide pillars 13 are fixed to the LED lamp body 1, and the carrying seat 3 is slidably connected to the first guide pillars 13;

[0037] When the bidirectional screw 14 rotates to drive the two derivation cassettes 17 to move under the guidance of the second guide column 15, in order to limit the movement stroke of the derivation cassettes 17 and prevent the two derivation cassettes 17 from being too close to each other, a retaining ring 18 is fixed on the outer side of the second guide column 15 and on both sides of the flat gear 16;

[0038] The second guide column 15 is also symmetrically sleeved with a second spring 19, one end of each of the two second springs 19 is fixed to the LED lamp body 1, and the other ends of the two second springs 19 are respectively fixed to the two derivation holders 17, so that the two derivation holders 17 are always in close contact with the two retaining rings 18 under the pressure of the two second springs 19, and thus a greater force is required to rotate the bidirectional screw 14 to drive the derivation holder 17 to move, so that the bidirectional screw 14 is not easy to rotate in non-human conditions;

[0039] The use process of the LED matrix light source provided by the utility model is as follows: when it is necessary to assemble multiple LED lamp bodies 1 to form a matrix light source, the multiple LED lamp bodies 1 need to be fitted together first. Before fitting together, the drooping limit block 10 is first rotated so that its lower end is no longer fitted with the connecting plate 8, thereby releasing the limit on the connecting plate 8, and then grabbing and pulling up the connecting plate 8 to drive the two pull rods 6 to move in the direction away from the LED lamp body 1, thereby facilitating the sliding of the mounting seat 3 into the inner side of the slide groove 12, and cooperating with the first guide column 13 to facilitate the sliding of the mounting seat 3, so that during the sliding process of the mounting seat 3, the meshing of the rack 4 and the flat gear 16 drives the bidirectional screw 14 to rotate, thereby driving the two derivation clamping seats 17 to gradually move away from each other through the guidance of the second guide column 15, and gradually squeeze the second spring 19 during the movement, and at the same time, in conjunction with the structural design of the triangular clamping slot 2, the two derivation clamping seats 17 gradually penetrate into the inner side of the triangular clamping slot 2;

[0040] When the mounting seat 3 completely slides into the inner side of the slide groove 12, the two derivation seats 17 also completely enter the inner side of the triangular slot 2, and then the connecting plate 8 is loosened to drive the two pull rods 6 to reset through the elastic characteristics of the first spring 7, so that the two pull rods 6 both penetrate the LED lamp body 1 and slide into the two derivation seats 17 respectively, and the derivation seats 17 are limited and fixed, so that the derivation seats 17 cannot slide out of the triangular slot 2, and then the two LED lamp bodies 1 are attached to each other and assembled. At this time, the weight of the drooping limit block 10 is used to make its lower end fit with the connecting plate 8 again, and then the position of the pull rod 6 and the connecting plate 8 is limited, and the stability of the two LED lamp bodies 1 after assembly is further improved.
