[0028] See also Figure 1 and Figure 2 A strip light source includes an aluminum frame 1, a light-transmitting plate 2, an aluminum base plate 3, a plurality of SMD lamp beads 4 and two aluminum plate covers 5.

[0029] A lamp groove 1a is provided on the first side of the aluminum frame 1, and a first groove 1b is provided on the second side opposite to the first side. Specifically, the aluminum frame 1 may include a base 1-1, two first ribs 1-2 and two second ribs 1-3, the two first ribs 1-2 are integrally provided on the first side of the base 1-1, and the two second ribs 1-3 are integrally provided on the second side of the base 1-1. Accordingly, the lamp groove 1a is formed between the two first ribs 1-2, and the first groove 1b is formed between the two second ribs 1-3.

[0030] The inner wall of the lamp trough 1a includes two symmetrical first inner walls 1a1 and a second inner wall 1a2 between the two first inner walls 1a1. The first inner wall 1a1 is the inner side wall of the first rib 1-2, and the second inner wall 1a2 is the first side surface of the base 1-1. The edges of the two first inner walls 1a1 away from the second inner wall 1a2 are provided with a first slot 1a3, and the edges close to the second inner wall 1a2 are provided with a second slot 1a4.

[0031] The middle position of the first groove 1b is provided with a first installation groove 1b1 for the nut to enter. That is, after the nut enters the first installation groove 1b1, it can move along the direction of the first installation groove 1b1, and also fits the two opposite inner walls of the first installation groove 1b1 to limit the rotation of the nut itself. In this way, when the bolt penetrates the first installation groove 1b1 and is threadedly connected to the nut, the strip light source can be easily installed at the corresponding position. There are multiple first heat dissipation fins 1b2 on both sides of the first groove 1b.

[0032] See also Figure 3 and Figure 5 In some embodiments, the third and fourth sides of the aluminum frame 1 are both provided with second grooves 1c, and the middle position of the second groove 1c is provided with a second installation groove 1c1 for the nut to enter.

[0033] In this way, the strip light source can be installed at the corresponding position through the two second installation grooves 1c1. That is, the second side, the third side and the fourth side of the aluminum frame 1 can all be used for installation, and through multi-faceted installation, the strip light source can better adapt to different installation environments.

[0034] Furthermore, the cross section of the first groove 1b is trapezoidal, and the two waists correspond to the two second ribs 1-3, and the distance between the two second ribs 1-3 gradually increases as it moves away from the second inner wall 1a2. The two sides of the lamp groove 1a have outward extensions 1a5. The second groove 1c is formed by the extension 1a5 and the second ribs 1-3.

[0035] In some embodiments, the two first inner walls 1a1 are both parabolic surfaces. The distance between the two first inner walls 1a1 gradually increases as they are away from the second inner wall 1a2. Specifically, the two first inner walls 1a1 can be calculated by optical ASAP software.

[0036] In this way, on the one hand, light can be efficiently focused through the two first inner walls 1a1; on the other hand, combined with the above-mentioned setting of "the other opposite third side and fourth side of the aluminum frame 1 are both provided with a second groove 1c", the above-mentioned second groove 1c can be more conveniently formed between the first rib 1-2 and the second rib 1-3.

[0037] See also Figure 1 and Figure 3 The light-transmitting plate 2 is installed in the two first slots 1a3 of the aluminum frame 1. Specifically, the light-transmitting plate 2 can be directly inserted into the two first slots 1a3 by one end; or it can be made of a suitable material that can be bent and deformed, with one side edge installed in one first slot 1a3 first, and then the other side edge is installed in the other first slot 1a3 by bending and deforming.

[0038] The aluminum substrate 3 is installed in the two second slots 1a4 of the aluminum frame 1 , and after the aluminum substrate 3 is installed in the aluminum frame 1 , the aluminum substrate 3 is attached to the second inner wall 1a2 .

[0039] A plurality of SMD lamp beads 4 are mounted on the aluminum substrate 3. The heat generated by the SMD lamp beads 4 is easily transferred to the aluminum substrate 3, and through the bonding between the aluminum substrate 3 and the second inner wall 1a2, the heat is transferred to the aluminum frame 1, and the heat is dissipated by the plurality of first heat dissipation fins 1b2.

[0040] See also Figure 3 and Figure 5 In some implementations, combined with the above-mentioned setting of "a second groove 1c is provided on the third side and the fourth side opposite to each other of the aluminum frame 1", a plurality of second heat dissipation fins 1c2 are provided on both sides of the second groove 1c.

[0041] In this way, a portion of the second heat dissipation fins 1c2 is connected to the second rib 1-3 to assist the plurality of first heat dissipation fins 1b2; another portion of the second heat dissipation fins 1c2 is connected to the first rib 1-2 to dissipate the heat in the lamp trough 1a.

[0042] See also Figure 3 and Figure 4 The two aluminum plate covers 5 are detachably fixed to the two end positions of the aluminum frame 1 to block the two end surfaces of the light-transmitting plate 2 and the aluminum base plate 3.

[0043] See also Figure 1 and Figure 3 In some embodiments, a thread groove 1b3 is further provided in the first groove 1b of the aluminum frame 1. Specifically, two symmetrical F-shaped plates are integrally provided on the second side surface of the base 1-1, and a spacing is left between the two F-shaped plates. The two F-shaped plates and the base 1-1 each form two notches. The first mounting groove 1b1 is formed by two notches away from the base 1-1, and the thread groove 1b3 is provided in the base 1-1 and is located in the two notches close to the base 1-1.

[0044] In this way, the two aluminum plate covers 5 can be easily installed or removed by bolts.
