Description

[Technical Field]

[0001] This utility model mainly relates to a heat dissipation structure for a linear light. [Background Technology]

[0002] The main functions of LED linear lights are advertising decoration, urban lighting, building lighting, entrance lighting, indoor ceiling recessed lighting, jewelry display cases, wine cabinets, stair lighting, and other indoor and outdoor decorative lighting.

[0003] Many LED linear lights on the market generate a lot of heat during prolonged use, and this heat usually accumulates inside the LED light body, often causing abnormal overheating. Excessive temperature is also detrimental to the normal operation of the LED light. Therefore, we propose a heat dissipation structure for linear lights. [Utility Model Content]

[0004] To solve at least one of the above problems, this utility model proposes a new structural solution. The heat dissipation structure of this linear light adopts the following technical solution:

[0005] A heat dissipation structure for a linear light includes a lamp housing, a fan, and an LED light strip. The lamp housing includes a light-emitting part, a fan part, and a heat dissipation cavity. The fan is mounted on the fan part, and the LED light strip is inserted into the light-emitting part.

[0006] The heat dissipation cavity is located inside the lamp housing. An air duct is provided between the heat dissipation cavity and the fan section. The first end of the air duct is connected to the fan section, and the last end of the air duct is connected to the heat dissipation cavity. The size of the air duct gradually decreases from its first end to its last end.

[0007] Preferably, the light-emitting part is provided with a slot, the LED light strip is inserted into the slot, and the LED light strip is attached to the end face of the slot.

[0008] Preferably, the fan section has several insertion cavities, and the fan is disposed in the insertion cavities.

[0009] Preferably, the beginning of the air duct is round and the end of the air duct is flat.

[0010] Preferably, the end of the air duct branches to form a double air outlet, and the double air outlet is in a figure-eight shape.

[0011] Preferably, end caps are installed at both ends of the lamp housing, the end caps are hinged with feet, and the end caps are provided with slots that communicate with the heat dissipation cavity.

[0012] The beneficial effects of this utility model compared with the prior art are:

[0013] This structure primarily utilizes air cooling for heat dissipation. Heat generated by the LED strip connected to the lamp housing is transferred to the housing, mainly concentrated in the heat dissipation cavity. Airflow generated by the fan enters from the beginning of the air duct. As the duct gradually decreases in size from one end to the other, the airflow within the duct forms a high-speed, narrow airflow, reducing the overall temperature of the air. This cooled, high-speed airflow then enters the heat dissipation cavity, quickly expelling the hot air and achieving a cooling effect, thus extending the lifespan of the LED strip. It boasts advantages such as simple structure, compact design, and rational configuration; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The preferred embodiment provided by this utility model is as follows: Figures 1-3As shown, a heat dissipation structure for a linear light includes a lamp housing 1, a fan 2, and an LED light strip 3. The fan is a fan commonly used in personal computers. The lamp housing 1 includes a light-emitting part 4, a fan part 5, and a heat dissipation cavity 6. The fan 2 is installed in the fan part 5, and the LED light strip 3 is inserted into the light-emitting part 4. End caps 11 are installed at both ends of the lamp housing 1. The end caps 11 are hinged with feet 12 to facilitate rotation and adjustment of the light emission angle. The end caps 11 are provided with slots 13 that communicate with the heat dissipation cavity 6 to allow hot air in the heat dissipation cavity 6 to be discharged.

[0021] The light-emitting part 4 is provided with a slot 41, and the LED light strip 3 is disposed in the slot 41 and attached to the end face of the slot 41 to transfer the heat generated by the LED light strip 3 to the lamp housing 1. The light-emitting part 4 is provided with several lamp cups 44, and the position of the light source of the LED light strip corresponds to the position of the lamp cup. The light source adjusts its light emission range through the lamp cup, thereby reducing glare.

[0022] The fan section 5 is provided with several cavities 51. The fan 2 is placed in the cavity 51 and locked in the cavity 51 by screws. The heat dissipation cavity 6 is located in the lamp housing 1. A duct 7 is provided between the heat dissipation cavity 6 and the fan section 5. The first end of the duct 7 is connected to the fan section 5, and the last end of the duct 7 is connected to the heat dissipation cavity 6. The size of the duct 7 gradually decreases from its first end to its last end.

[0023] The heat dissipation cavity 6 is located between the slot 41 and the air duct 7. The air duct 7 is located in the lamp housing 1 and between the heat dissipation cavity 6 and the fan part 5. The fan part 5 is connected to the heat dissipation cavity 6 through the air duct 7. The first end of the air duct 7 is round and the end of the air duct 7 is flat. Furthermore, the end of the air duct 7 branches to form a double air outlet 71, and the double air outlet 71 is in the shape of an "eight", which increases the air outlet heat dissipation position and improves the heat dissipation efficiency of the air outlet 7.

[0024] Heat dissipation principle: This structure mainly uses air cooling for heat dissipation. The heat generated by the LED strip connected to the lamp housing is transferred to the lamp housing and is mainly concentrated in the heat dissipation cavity. The airflow generated by the fan 2 enters from the beginning of the air duct 7. As the size of the air duct 7 gradually decreases from the beginning to the end, the airflow in the air duct 7 will form a high-speed narrow airflow (turbulence), which reduces the overall temperature of the airflow (the Bernoulli effect causes a slight decrease in temperature when the air pressure drops). The cooled high-speed airflow enters the heat dissipation cavity 6 and quickly exhausts the hot air in the heat dissipation cavity 6, thereby achieving a cooling effect and improving the lifespan of the LED strip.
