Description

Technical Field

[0001] The utility model relates to the technical field of radiators of lighting devices, and in particular to an LED lighting device with increased heat dissipation efficiency. Background Art

[0002] The existing LED lighting device radiator is provided with a heat pipe radiator. When the lamp bead starts to light, the heat conducting plate transfers the heat of the base to the heat pipe radiator in a concentrated manner. The heat pipe radiator achieves the heat dissipation effect through natural convection cooling of the air. It does not require a fan, has no noise, is maintenance-free, safe and reliable, and greatly improves the heat dissipation efficiency of the LED lamp. A fixing rod is provided. When the bottom cover is moved toward one side of the lamp housing, the fixing rod is subjected to a pressure from the inner wall of the lamp housing. The fixing rod is bounced into the inside of the fixing rod groove through the elastic structure formed by the first spring and the bottom cover. When the fixing rod and the fixing groove are on the same horizontal plane, the fixing rod pops out into the fixing groove to fix the bottom cover.

[0003] However, in order to utilize natural air convection, the existing radiator easily accumulates a lot of dust in the LED lamp. Users seldom clean the top-mounted LED lamp. As the usage time increases, dust accumulation reduces the heat dissipation effect. After searching, it was found that the technical solution provided by the utility model with application number CN201921523439.7 also has the above-mentioned problems. Utility Model Content
