Description

Technical Field

[0001] The utility model relates to a heat dissipation device, in particular to a light guide column heat dissipation device, belonging to the technical field of lighting. Background Art

[0002] LED light guide is an optical component used for LED light source, and its main function is to effectively guide, transmit and disperse the light emitted by LED. Light guide is usually made of highly light-transmitting materials, such as optical glass, acrylic resin (PMMA) or polycarbonate (PC). The design and application of LED light guide is very extensive. In the application scenario that requires uniform lighting of a large area, the light guide can convert the point light source emitted by the LED into a surface light source to achieve uniform lighting.

[0003] The light guide column of a common LED light source often does not have an auxiliary heat dissipation device. When a high-power LED light source is working, the temperature of the light guide column is too high, and common low-cost PC and PMMA optical materials cannot be used. Only high-cost optical glass and other high-temperature resistant optical materials can be used, which increases the production cost. Moreover, when the temperature of the light guide column is too high, the stability of the product will be poor. Therefore, a heat dissipation device for the light guide column is proposed. Utility Model Content

[0004] In view of this, the utility model provides a light guide column heat dissipation device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0005] The technical solution of the embodiment of the utility model is implemented as follows: a light guide column heat dissipation device includes a heat dissipation assembly, the heat dissipation assembly includes a heat dissipation cover, an internal air flow hole, four mounting grooves, an external bevel, a top air flow hole, a top bevel, four mounting frames and four heat dissipation fans;

[0006] The internal air flow holes are evenly opened at the lower part of the inner wall of the heat dissipation cover, the outer bevel is opened at the lower part of the outer wall of the heat dissipation cover, four installation grooves are symmetrically opened at the outer wall of the outer bevel, the top bevel is opened at the upper surface of the heat dissipation cover, the heat dissipation fan is installed on the inner wall of the installation frame, and the top air flow hole is opened on the inner wall of the top bevel.

[0007] Further preferably, the outer side walls of the four installation frames are symmetrically fixedly connected to the inner side walls of the four installation grooves, and the four heat dissipation fans are all tiltedly placed inside the heat dissipation cover.

[0008] Further preferably, the heat dissipation assembly further includes four supporting feet and a limiting mounting sleeve;

[0009] The top ends of the four support legs are symmetrically fixedly connected to the lower surface of the heat dissipation cover, and the position limiting mounting sleeve is fixedly connected to the upper portion of the inner side wall of the heat dissipation cover.

[0010] Further preferably, the internal air flow hole is located below the limiting mounting sleeve.

[0011] Further preferably, a main body component is installed inside the position-limiting installation sleeve, and the main body component includes a mounting base, an LED light source and a light guide column;

[0012] The light guide column is fixedly connected to the inner side wall of the position-limiting mounting sleeve, and the LED light source is installed at the center of the upper surface of the mounting base.

[0013] Further preferably, the LED light source is located inside the heat dissipation cover, and the light guide column is located above the LED light source.

[0014] Further preferably, the position of the internal air flow hole corresponds to the position of the LED light source.

[0015] Further preferably, the bottom end of the supporting foot is fixedly connected to the upper surface of the mounting base.

[0016] Since the embodiment of the utility model adopts the above technical scheme, it has the following advantages: the utility model starts the heat dissipation fan, and the external air flow flows into the heat dissipation cover through the installation groove, and then flows out from the internal air flow holes and the top air flow holes respectively. The air flow blown out of the internal air flow holes contacts the LED light source, and then flows out from the gap between the heat dissipation cover and the installation base, so as to dissipate the heat of the LED light source. The air flow blown out from the top air flow holes flows upward and contacts the light guide column, so as to dissipate the heat of the light guide column, and the temperature of the light guide column will not be too high, thereby ensuring the stability of the product. Moreover, by dissipating the heat of the LED light source, the heat absorbed by the light guide column can be reduced, so that lower-cost PC and PMMA optical materials can be used, thereby reducing production costs.

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown in FIG. 4 , the embodiment of the utility model provides a light guide column heat dissipation device, including a heat dissipation assembly 101, the heat dissipation assembly 101 includes a heat dissipation cover 11, an internal air flow hole 12, four mounting grooves 13, an outer bevel 14, a top air flow hole 15, a top bevel 16, four mounting frames 17 and four heat dissipation fans 18;

[0027] The internal air flow holes 12 are evenly opened on the lower part of the inner wall of the heat dissipation cover 11, the outer bevel 14 is opened on the lower part of the outer wall of the heat dissipation cover 11, four installation grooves 13 are symmetrically opened on the outer wall of the outer bevel 14, the top bevel 16 is opened on the upper surface of the heat dissipation cover 11, the heat dissipation fan 18 is installed on the inner wall of the installation frame 17, and the top air flow hole 15 is opened on the inner wall of the top bevel 16, and the top bevel 16 is a conical bevel that is concave inward.

[0028] In one embodiment, the outer walls of the four mounting frames 17 are symmetrically fixedly connected to the inner walls of the four mounting grooves 13, and the four cooling fans 18 are all tiltedly placed inside the cooling cover 11. When the cooling fans 18 are working, the external air can flow into the interior of the cooling cover 11 through the mounting grooves 13. Since the cooling fans 18 are tilted, the cooling fans 18 can be prevented from directly blowing the internal air flow holes 12 or the top air flow holes 15. The air flow will first flow into the cooling cover 11, and then flow out from the internal air flow holes 12 and the top air flow holes 15 at the same time.

[0029] In one embodiment, the heat dissipation assembly 101 further includes four support legs 20 and a position limiting mounting sleeve 19;

[0030] The top ends of the four supporting feet 20 are symmetrically fixedly connected to the lower surface of the heat dissipation cover 11, the limiting mounting sleeve 19 is fixedly connected to the upper part of the inner wall of the heat dissipation cover 11, and the internal air flow hole 12 is located below the limiting mounting sleeve 19. The position of the heat dissipation cover 11 can be limited by the supporting feet 20, and the position of the light guide column 33 can be limited by the limiting mounting sleeve 19.

[0031] In one embodiment, a main body component 301 is installed inside the position-limiting installation sleeve 19, and the main body component 301 includes a mounting base 31, an LED light source 32, and a light guide column 33;

[0032] The light guide column 33 is fixedly connected to the inner wall of the limiting mounting sleeve 19, the LED light source 32 is installed at the center of the upper surface of the mounting base 31, the LED light source 32 is located inside the heat dissipation cover 11, and the light guide column 33 is located above the LED light source 32. The position of the internal air flow hole 12 corresponds to the position of the LED light source 32. Therefore, when the cooling fan 18 is working, the airflow in the heat dissipation cover 11 flows out from the internal air flow hole 12 and the top air flow hole 15 at the same time. The airflow flowing out from the internal air flow hole 12 can dissipate heat for the LED light source 32, and the airflow flowing out from the top air flow hole 15 can dissipate heat for the light guide column 33.

[0033] In one embodiment, the bottom end of the support foot 20 is fixedly connected to the upper surface of the mounting base 31, and the heat dissipation cover 11 can be separated from the mounting base 31 through the support foot 20. When the internal air flow hole 12 blows out air flow to dissipate heat from the LED light source 32, the air flow carries the heat and flows out from the gap between the heat dissipation cover 11 and the mounting base 31.

[0034] When the utility model is working, the LED light source 32 is powered on, and the light emitted by the LED light source 32 is irradiated on the light guide column 33. The light can be converted into a surface light source through the light guide column 33 to achieve uniform lighting, which is suitable for scenes requiring uniform lighting of a large area. As the LED light source 32 works, heat is generated inside and absorbed by the light guide column 33. The heat dissipation fan 18 is started. At this time, the external airflow flows into the heat dissipation cover 11 through the installation groove 13, and then flows out from the internal airflow hole 12 and the top airflow hole 15 respectively. The airflow blown out of the internal airflow hole 12 is in contact with the LED light source 32. The light from the top of the light guide column 33 is heated up and contacts the light guide column 33, thereby cooling the light guide column 33. ...

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
