[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 1-4 , an imitation sodium light source LED lamp, comprising a lamp tube 1, the lamp tube 1 can be a hollow cylinder, the outer surface of the lamp tube 1 is provided with a plurality of annularly distributed card strips 11, the card strip 11 can be T-shaped, and the plurality of card strips 11 are arranged along the axial direction of the lamp tube 1, and a card slot 12 is provided between two adjacent card strips 11, and a full-spectrum light strip 2 is arranged in the card slot 12, and the bottom of the card slot 12 can be a plane, which is convenient for the installation and fixation of the full-spectrum light strip 2, and the full-spectrum light strip 2 is arranged along the axial direction of the lamp tube 1, a lamp holder 3 is provided at one end of the lamp tube 1 for connecting to an external power supply, and a limiting collar 4 is provided at the other end, and the limiting collar 4 can be a circular plate for fixing the end of the full-spectrum light strip 2 to prevent the full-spectrum light strip 2 from sliding in the card slot 12 or falling off from the card slot 12; the plurality of full-spectrum light strips 2 are electrically connected to the lamp holder 3, and the plurality of full-spectrum light strips 2 can be lighted through the rotation connection of the lamp holder 3, thereby realizing the imitation sodium lamp lighting effect of the light source.

[0023] In some embodiments, the full-spectrum light strip 2 can be a long strip of LED light board, including a substrate 21. The substrate 21 can be an aluminum plate, which not only provides a solid support, but also helps to conduct and dissipate heat, thereby improving the heat dissipation effect; the substrate 21 is inserted into the card slot 12, and a detachable connection between the substrate 21 and the card slot 12 can be achieved, which is convenient for the later replacement of the full-spectrum light strip 2. A plurality of lamp beads 22 are arranged on the substrate 21, and the plurality of lamp beads 22 are evenly distributed along the length direction of the substrate 21 to ensure the uniform distribution and coverage of light.

[0024] In some embodiments, the lamp bead 22 can be a four-primary color powder-free LED lamp bead, which can provide a full spectrum of light, has higher color rendering, and is closer to natural light. It can also control the ratio of the four colors R, G, B, and Y by changing the output current ratio of each channel according to the needs of different time periods, thereby achieving variable color temperature to meet the lighting needs of different occasions.

[0025] In some embodiments, at least four mounting seats 5 are provided in the lamp tube 1, and the mounting seats 5 include a fixing tube 51, and a connecting plate 52 is provided between the fixing tube 51 and the inner wall of the lamp tube 1. The fixing tube 51 and the connecting plate 52 are both arranged along the axial direction of the lamp tube 1, and the inner walls at both ends of the fixing tube 51 are provided with threads. The four mounting seats 5 are provided with a limit collar 4 at one end away from the lamp holder 3, and a heat dissipation fan 6 is also provided in the lamp tube 1. The heat dissipation fan 6 is fixed to the end of the four mounting seats 5 close to the lamp holder 3, and can be screwed with the threads at both ends of the fixing tube 51 by bolts to achieve the fixing of the limit collar 4 and the heat dissipation fan 6; at the same time, through the connection between the limit collar 4 and the heat dissipation fan 6, the connection strength between the inner walls of the lamp tube 1 can be enhanced, thereby improving the stability of the structure of the imitation sodium light source LED lamp. The heat dissipation fan 6 is electrically connected to the lamp holder 3, and when the light source is working, the heat dissipation fan 6 will start, thereby enhancing the heat dissipation effect of the light source and extending its service life.

[0026] In some embodiments, the lamp holder 3 is provided with threads on the outside, which can be connected to a threaded seat, so as to facilitate maintenance and replacement.

[0027] The specific working principle is as follows:

[0028] When the external power source supplies power to the sodium-like LED lamp through the lamp holder 3, the lamp beads 22 on the full-spectrum light strip 2 will emit light, and multiple ring-shaped full-spectrum light strips 2 will emit light at the same time, forming multiple long reflective strips on the surface of the lamp tube 1, thereby achieving the sodium-like lighting effect of the light source; at the same time, the cooling fan 6 will also start to discharge the heat inside the lamp tube 1 to maintain the stable operation of the light source. Due to the use of four-primary color powder-free LED lamp beads, the color rendering of the light source has been significantly improved, so it can replace high-pressure sodium lamps for various lighting occasions.

[0029] In addition, by adjusting the current ratio of each output, the ratio of the four colors R, G, B, and Y can be controlled to achieve variable color temperature. In this way, users can flexibly adjust the color temperature of the light source according to the lighting needs of different time periods or different occasions to achieve better lighting effects.
