Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a tubular spotlight radiator structure. Background Art

[0002] LED downlights are products developed based on traditional downlights using new LED lighting sources. Compared with traditional downlights, they have the following advantages: energy saving, low carbon, long life, good color rendering, and fast response. The design of LED downlights is more beautiful and lightweight, and some downlights are floor lamps that can be carried.

[0003] At present, the heat dissipation of LED cylindrical spotlights is generally achieved by opening a heat dissipation port at the end of the shell, and cooperating with a heat dissipation tube to conduct the heat to the outside. However, when there are multiple lamp beads in the cylindrical spotlight, the multiple lamp beads work for a long time at the same time, and the heat generated is relatively large. The heat generated in the shell is greater than the heat dissipated, which will cause the heat to accumulate inside the shell. This will seriously affect the service life of the lamp beads for a long time and even cause damage to the lamp beads. For this reason, we propose a cylindrical spotlight radiator structure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] See also Figure 1-4 The utility model provides a technical solution: a cylindrical spotlight heat sink structure, including a shell 1, a mounting plate 2 and lamp beads 7, one end of the shell 1 is fixedly mounted with the mounting plate 2, and the surface of the mounting plate 2 is equidistantly mounted with lamp beads 7.

[0019] Strip vents 3 are equidistantly provided on the outside of the shell 1, and the strip vents 3 are located on the outside of the shell 1. An electric control board for controlling the lamp beads 7 is provided on the side of the mounting plate 2 away from the lamp beads 7. When the lamp beads 7 are working, one end of the strip vents 3 is located between the annular heat sink 8 and the mounting plate 2, so that part of the heat can be discharged to the outside through the strip vents 3, and the annular heat sink 8 can perform heat conduction to achieve rapid heat extraction. An annular heat sink 5 is provided on the end of the shell 1 away from the mounting plate 2, and heat sink fins 6 are equidistantly connected to the outside of the annular heat sink 5, and the ends of the heat sink fins 6 pass through the shell 1.

[0020] It should be noted that when the lamp bead 7 is working, part of the heat generated is discharged through the bottom end of the strip vent 3, and the other part is conducted to the top of the shell 1 through the heat-conducting column 9 and the annular heat sink 8, and then conducted to the outside through the annular heat sink 5 and the heat sink fins 6. At the same time, the heat dissipation fan 11 works to quickly discharge the heat through the strip vent 3 and the heat dissipation port 13.

[0021] An annular heat sink 8 is fixedly connected to one end of the mounting plate 2 in the housing 1 , and a heat conducting column 9 is equidistantly fixedly connected to one side of the mounting plate 2 , and the end of the heat conducting column 9 contacts the mounting plate 2 .

[0022] It should be noted that an electric control board for controlling the lamp beads 7 is arranged on the side of the mounting plate 2 away from the lamp beads 7. The electric control board generates heat when it works. The annular heat sink 8 is connected to the electric control board on the mounting plate 2 through the heat conducting column 9, so that the heat is directly conducted out to achieve the purpose of heat dissipation.

[0023] A mounting rod 10 is fixedly connected between the annular heat dissipation plate 8 and the annular heat dissipation tube 5 in the housing 1 , and a heat dissipation fan 11 is installed in the middle of the mounting rod 10 .

[0024] It should be noted that by controlling the operation of the cooling fan 11, cold air can quickly enter between the mounting plate 2 and the annular heat dissipation plate 8 through the bottom end of the strip heat dissipation port 3, quickly dissipating the internal heat, and the heat reaches the annular heat dissipation tube 5 and multiple heat dissipation fins 6, so that the heat is quickly conducted to the outside, thereby achieving the purpose of efficient heat dissipation.

[0025] One end of the housing 1 located at the annular heat dissipation tube 5 is connected to a cover 4 , and heat dissipation openings 13 are equidistantly formed on the surface of the cover 4 .

[0026] It should be noted that the housing 1 can be sealed by the cover 4 , and the heat dissipation openings 13 on the cover 4 are helpful for discharging heat.

[0027] The cover 4 is located on one side of the housing 1 and is fixedly connected with a strip dust filter plate 12 at equal intervals, and the strip dust filter plate 12 is connected in cooperation with the inside of the strip vent 3 .

[0028] It should be noted that the strip dust filter plate 12 is integrally connected to the cover 4. When the cover 4 is connected to the outer shell 1, the strip dust filter plate 12 thereon is connected to the inside of the strip vent 3 to achieve the effect of ventilation and dust filtering, thereby preventing dust from entering the inner part of the outer shell 1 and affecting heat dissipation.

[0029] A dustproof net 14 is disposed inside the heat dissipation opening 13 .

[0030] It should be noted that a dustproof net 14 is arranged in each heat dissipation port 13 on the cover 4 to prevent external dust from entering the housing 1 through the heat dissipation port 13, thereby avoiding dust accumulation inside the housing 1 and being difficult to clean.
