Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a heat dissipation cover of an LED lamp. Background Art

[0002] LED is a solid-state semiconductor element that directly converts electrical energy into visible light. Compared with traditional lamps, LED lamps have the advantages of high brightness, low energy consumption, long life, energy saving and environmental protection. However, when using high-power LED lamps, they will generate high temperatures. In addition to affecting the luminous efficiency of the LED bulb, this high temperature will also damage the LED bulb and reduce its service life. Therefore, solving the heat dissipation problem during the operation of LED lamps has become one of the most important issues in the industry.

[0003] After searching, the Chinese patent announcement number CN210891565U discloses "a heat dissipation cover of an LED lamp, comprising: an annular bottom cover and at least one annular upper cover; and the annular upper cover is arranged on the annular bottom cover and forms a top connecting part and an edge connecting part, and a gap is formed between the inner wall of the annular upper cover and the outer wall of the annular bottom cover."

[0004] The above patent achieves heat dissipation for the LED lamp by opening an "open hole" on the "annular upper cover" so that the external cold air is introduced into the inside of the "annular upper cover" so that the external cold air and the hot air inside the "annular upper cover" can exchange heat. However, since the specific heat capacity of air is small, the thermal conductivity of air is poor, and the heat dissipation effect of the LED lamp is not good. In addition, the specific heat capacity of liquid is large and the heat dissipation effect is better, but the above patent does not use liquid cooling to dissipate heat. Utility Model Content
