[0032] Example 1

[0033] like Figure 1-7 As shown, the LED lens heat dissipation module proposed by the present invention includes a housing 2, a flow guide component 3, a heat dissipation fan 5 and a heat dissipation plate;

[0034] The housing 2 is disposed on the back of the LED light source 1. One end surface of the housing 2 is provided with a second air inlet 10 for communicating the interior space of the housing 2 with the exterior space of the housing 2 via the back of the LED light source 1 in a heat dissipation state. The LED light source 1 has the same structure as the LED light source in the heat dissipation mechanism of an LED lens module disclosed in the Chinese patent document with authorization publication number CN208418588U in the background art. The LED light source 1 in this embodiment is shown in the figure for illustration only.

[0035] The heat sink is provided on the back of the built-in driver 11 and mounted on the inner side of the other end of the housing 2. A plurality of third air inlet holes 12 are provided on one end surface of the heat sink and near the edge for connecting the internal space of the housing 2 with the space at the other end of the heat sink in the heat dissipation state. The built-in driver 11 has the same shape as the built-in driver in the heat dissipation mechanism of an LED lens module disclosed in the Chinese patent document with the authorization announcement number CN208418588U in the background art. In this embodiment, the built-in driver 11 is fixed directly to the heat sink by screws or fixed to the heat sink by screws and clamping plates during installation. Secondly, the built-in driver 11 in this embodiment is only schematically shown in the figure.

[0036] The heat dissipation fan 5 is installed at the other end of the heat dissipation plate and is used to start when in use to suck the heat absorbed and dissipated by the heat dissipation plate to the outside, thereby cooling the heat dissipation plate and then cooling the built-in driver 11;

[0037] The guide component 3 is installed on the inner side of the heat sink and wrapped around the outer side of the third air inlet 12, with one end facing the heat dissipation fan 5, so that when the heat dissipation fan 5 sucks the heat sink, the guide component 3 cooperates with the heat sink, the third air inlet 12 and the second air inlet 10 to form an external air flow channel.

[0038] In an optional embodiment, the other end of the shell 2 is open, one end of the heat sink is inserted into the opening of the shell 2, and one end of the heat sink is sealed to the opening of the shell 2, so that the heat sink closes the opening of the shell 2 when in use.

[0039] In an optional embodiment, a plurality of mounting seats 9 are provided on one end face of the shell 2, and the LED light source 1 is mounted on the mounting seat 9 by screws. The mounting seat 9 separates the LED light source 1 from the shell 2, so that there is a gap between the LED light source 1 and the shell 2, and the gap is greater than or equal to 1 mm, and the outside air moves to the inner side of the shell 2 through the LED light source 1.

[0040] The heat dissipation fan 5 is a device that is used to dissipate heat from the heat sink 11 to the outside of the housing 2. The device is used to dissipate heat from the heat sink 11 to the outside of the housing 2. The device is used to dissipate heat from the heat sink 11 to the outside of the housing 2.

[0041] Example 2

[0042] like Figure 5-7 As shown, the LED lens heat dissipation module proposed by the present invention, compared with the first embodiment, in this embodiment, the heat dissipation plate includes a second heat sink 6 and a mounting plate 8;

[0043] The mounting plate 8 is provided on the back of the built-in driver 11 and mounted on the inner side of the other end of the housing 2;

[0044] There are multiple second heat sinks 6 , which are arranged at equal distances on the back of the mounting plate 8 and located at the upper and lower edges of the third air inlet 12 .

[0045] In this embodiment, the built-in driver 11 is installed through the mounting plate 8, so that the heat transfer area between the built-in driver 11 and the mounting plate 8 is maximized, and the heat of the mounting plate 8 is transferred and dissipated through the second heat sink 6. At the same time, the number of second heat sinks 6 is multiple, so that the heat dissipation area of ​​the mounting plate 8 is increased, thereby improving the heat dissipation efficiency.

[0046] Example 3

[0047] like Figure 1-4 As shown, the present invention proposes an LED lens heat dissipation module. Compared with the first embodiment, in this embodiment, a first air inlet hole 7 is provided on the side of the shell 2 and located on the side of the built-in driver 11 and the positive side of the third air inlet hole 12.

[0048] In this embodiment, the internal space of the shell 2 is connected with the external space through the first air inlet hole 7 on the side of the shell 2, so that when the LED light source 1 is sealed and installed, the outside air flows through the built-in driver 11 to the third air inlet hole 12 through the first air inlet hole 7, and the flow direction is perpendicular or parallel to the side of the third air inlet hole 12, so that the outside air completely covers the built-in driver 11 when flowing to the third air inlet hole 12, thereby dissipating heat for the entire built-in driver 11.

[0049] Example 4

[0050] like Figure 5-6 As shown, the LED lens heat dissipation module proposed by the present invention, compared with the first embodiment, in this embodiment, the guide component 3 includes a blocking plate 31 and a guide plate 32;

[0051] There are two blocking plates 31, both of which are arranged on the back of the mounting plate 8 and connected to the second heat sink 6. The two blocking plates 31 are respectively located on the left and right sides of the third air inlet 12, and are used to connect the two guide plates 32 and the second heat sink 6 to form a channel with open ends when in use.

[0052] There is at least one guide plate 32, which is installed on the side of the blocking plate 31 and connected to the second heat sink 6. It is used to block the channel formed by the guide plate 32 and the second heat sink 6 when in use, so that the air moving from the third air inlet 12 to the cooling fan 5 is guided, and the external air is discharged outward from the second heat sink 6 as a whole, thereby improving the heat dissipation efficiency of the second heat sink 6.

[0053] It should be noted that the length direction of the second heat sink 6 is arranged along the direction from the third air inlet hole 12 to the first air inlet hole 7 , and the guide plate 32 is vertically connected to the second heat sink 6 .

[0054] In an optional embodiment, first heat sinks 4 are provided on the sides of the two blocking plates 31 , and the heat on the blocking plates 31 is dissipated over a large area through the first heat sinks 4 , thereby improving the overall heat dissipation effect.

[0055] In this embodiment, two guide plates 32 are used to connect the second heat sink 6 to form a channel with open ends, and the third air inlet 12 is located inside the channel. When the heat dissipation fan 5 is working, the heat dissipation fan 5 sucks the inside of the channel, so that the outside air flows to the inside of the channel through the third air inlet 12. At the same time, the air is guided by the guide plate 32, so that the outside air passes through the entire second heat sink 6 and is discharged to the outside, thereby improving the heat dissipation efficiency of the second heat sink 6 and the overall heat dissipation effect.

[0056] In summary, in the present invention, the built-in driver 11 is installed through the mounting plate 8, so that the heat transfer area between the built-in driver 11 and the mounting plate 8 is maximized, and the heat of the mounting plate 8 is transferred and dissipated through the second heat sink 6. At the same time, the number of the second heat sink 6 is multiple, so that the heat dissipation area of ​​the mounting plate 8 is increased. At the same time, the heat dissipation fan 5 sucks the second heat sink 6 and the mounting plate 8, so that the second heat sink 6 and the dissipated heat are quickly dissipated through the heat dissipation fan 5, and is connected to the second heat sink 6 through two guide plates 32 to form a channel with open ends, so that when the heat dissipation fan 5 sucks, suction is generated between the channel and the inner side of the shell 2, and at the same time, a gap is provided between the LED light source 1 and the shell 2 after installation through the mounting seat 9, so that the heat dissipation fan 5 draws external air through the LED light source 1 and through The second air inlet 10 opened on the end face of the shell 2 and the first air inlet 7 opened on the side face of the shell 2 flow toward the inside of the shell 2, and the outside air directly cools down the LED light source 1 and the built-in driver 11. At the same time, the outside air continues to move toward the inside of the channel through the third air inlet 12. During the movement, the guide plate 32 guides its movement direction, so that the outside air drives the heat of the second heat sink 6 to be discharged outward after passing through the entire second heat sink 6, thereby improving the heat dissipation efficiency of the second heat sink 6 and the overall heat dissipation effect. At the same time, the outside air is directed through the first air inlet 7 through the built-in driver 11 to flow to the third air inlet 12, and the built-in driver 11 is cooled as a whole, thereby preventing the external space of the second air inlet 10 from being connected to the internal space of the shell 2 when the LED light source 1 is sealed and installed.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
