LED lamp cooling structure

Abstract

The invention discloses an LED lamp cooling structure. An LED lamp includes a substrate uniformly provided with multiple LED beads on the upper end surface; the cooling structure can be mounted on the LED lamp, and is tightly bonded and fixed on the lower end surface of the substrate; the cooling structure includes a radiator with a hollow internal, and a cooling silica gel layer tightly butted against the outer side wall of the radiator and having a heat conducting effect; multiple cooling ribs are arranged on the outer side wall of the cooling silica gel layer; the cooling ribs and the cooling silica gel layer are set as an integral forming structure, and are manufactured by a heat conducting composite material; multiple cooling fins are uniformly distributed on the inner side wall of the radiator; and the cooling fins and the radiator are set as an integral forming structure, and are manufactured by heat conducting metal. In the cooling structure, the cooling silica gel layer with good cooling performance is encircled around the outer side wall of the radiator with good heat conducting effect for dissipating heat conducted during working of the LED beads into external air by the quickest speed to achieve the ideal cooling effect; and the LED lamp cooling structure is simple in structure, reasonable in design, ideal in cooling effect and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a heat dissipation structure of LED lamps. Background technique [0002] LED has been widely used in various lamps because of its advantages of energy saving, environmental protection, small size, and fast response. However, the light efficiency of LED lamps is only about 15% to 30%, and most of the remaining energy is converted into heat energy. The luminous rate and luminous quality will decrease with the increase of temperature. If the heat generated by the LED lamp bead is not dissipated in time, the accumulated heat will cause the temperature of the LED lamp bead to be too high, thus affecting the luminous efficiency and performance of the LED lamp. Shortened service life. Therefore, the heat dissipation problem of LED lamps directly affects the service life of LED lamp beads. For the heat dissipation problem of LED lamps, there are various heat dissipation structures on...
