[0002] In today's lighting field, LED lamp has been widely applied by virtue of its energy saving, long service life, high luminous efficiency and many other advantages. However, heat will be generated during the working process of LED lamp, and the heat dissipation problem has always been a key factor restricting its performance and service life.

[0003] Some existing LED lamp heat dissipation designs have obvious deficiencies. Some LED lamps only rely on simple heat sinks for natural heat dissipation, which has low heat dissipation efficiency and is difficult to meet the heat dissipation needs of high-power LED lamps. When LED lamp works for a long time, the generated heat cannot be dissipated in time, which will cause the temperature of LED chip to rise, and then cause a series of problems. On the one hand, high temperature will reduce the luminous efficiency of LED lamp, cause light decay, reduce the brightness of illumination and cause color deviation, which will affect the quality of illumination. On the other hand, high temperature will accelerate the aging of LED chip and other electronic components, shorten the service life of LED lamp, increase the use cost and replacement frequency.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] REFERENCE Figures 1-5The embodiment provides a LED lamp with good heat dissipation effect, which comprises a lamp body shell 1, an outer threaded connection port 2 is arranged at the lower end of the lamp body shell 1, an LED light source plate 6 is arranged at the position close to the outer threaded connection port 2 in the lamp body shell 1, a heat dissipation plate 9 is arranged above the LED light source plate 6 in the lamp body shell 1, a plurality of lamp beads 7 are fixedly connected to the lower end surface of the LED light source plate 6 at equal angles, a plurality of heat conduction pipes 14 are fixedly connected to the lower end of the heat dissipation plate 9, each heat conduction pipe 14 corresponds to one lamp bead 7, heat dissipation fins 11 are fixedly connected to the upper end surface of the heat dissipation plate 9, a support 12 is fixedly connected to the central position of the upper end surface of the heat dissipation plate 9, a heat dissipation fan 13 is installed at the upper end of the support 12, the heat dissipation fan 13 is electrically connected with an external power supply, four through holes 8 are formed in the upper end of the LED light source plate 6 at equal angles, through holes 10 are formed in the upper end of the heat dissipation plate 9 and correspond to the positions of the through holes 8, four internally threaded mounting columns 15 are fixedly connected to the inner wall of the lamp body shell 1 at equal angles, the four internally threaded mounting columns 15 correspond to the positions of the through holes 8 and the through holes 10, a plurality of air inlets 5 are formed in the outer wall of the lamp body shell 1 at equal angles, dust screens 17 are attached to the inner side of the air inlets 5 in the inner wall of the lamp body shell 1, a plurality of air outlets 4 are formed in the upper end surface of the lamp body shell 1 at equal angles and penetrate the inside of the lamp body shell 1, dust screens 16 are attached to the inner side of the air outlets 4 in the inner wall of the lamp body shell 1, and a transparent lamp shade 3 is threadedly connected to the lower end of the lamp body shell 1 through the outer threaded connection port 2.

[0025] Working principle: when in the installation process, through four bolts respectively through four through holes one 8 and the corresponding through hole two 10, the LED light source plate 6 and the heat sink plate 9 are strung together, and then the bolt is screwed into the corresponding internal threaded mounting column 15, the LED light source plate 6 and the heat sink plate 9 are firmly fixed in the lamp body shell 1, which ensures that the heat pipe 14 can be closely attached to the LED light source plate 6. After the LED lamp is connected to the external power supply, the lamp beads 7 on the LED light source plate 6 begin to emit light, and the lamp beads 7 as the main heat source will generate a large amount of heat. Since the position of the heat pipe 14 corresponds to the lamp beads 7 and is closely attached to the LED light source plate, the heat generated by the lamp beads 7 will be quickly conducted to the heat sink plate 9 through the heat pipe 14. The heat sink plate 9 has good heat conduction performance and can evenly disperse the heat to the entire heat sink plate 9, and then transfer to the heat dissipation fins 11 fixed on the end surface of the heat sink plate 9. The heat dissipation fins 11 increase the heat dissipation area and speed up the heat dissipation speed to the surrounding air. At the same time, the heat dissipation fan 13 connected with the external power supply starts to start. When the heat dissipation fan 13 operates, a negative pressure is formed in the lamp body shell 1, and the external cold air enters the lamp body shell 1 through the air inlet 5 on the outer wall of the lamp body shell 1. Since the air inlet 5 and the heat dissipation fins 11 are at the same horizontal position, the cold air will directly blow on the heat dissipation fins 11 after entering, and take away the heat on the heat dissipation fins 11. Under the action of the heat dissipation fan 13, the air outlet 4 on the upper end surface of the lamp body shell 1 is discharged to the outside of the lamp body, forming a continuous air circulation, which continuously takes away the heat generated by the LED lamp, thereby effectively reducing the working temperature of the LED lamp and ensuring the normal and stable operation of the LED lamp. The dust screen two 17 inside the air inlet 5 and the dust screen one 16 inside the air outlet 4 play a filtering role, preventing external dust from entering the inside of the lamp body shell 1, protecting the LED light source plate 6, the heat sink plate 9, the heat dissipation fins 11 and other components from being affected by dust, and maintaining the high efficiency of the heat dissipation system and the overall stability of the LED lamp.
