Problems solved by technology

[0004] However, due to the high heat generation of LEDs, in order to dissipate the heat in time, the volume of the radiator is generally made larger to obtain a larger heat dissipation area, which makes the transportation of the LED lamps inconvenient. and, since these light-emitting diodes are located on the same side of the heat sink, the light emitted by them can only radiate outward from this side of the heat sink, and the luminous angle is limited, so it cannot illuminate the surroundings of the lamp at the same time, and the lighting effect is not good.

Embodiment Construction

[0013] Such as figure 1 and 2 As shown, the LED lamp of the present invention includes a heat sink 10 and a plurality of LED modules 20 attached to the outer wall 120 of the heat sink 10 .

[0014] Please also refer to image 3 , the above-mentioned heat sink 10 is made of a metal material with good thermal conductivity, which includes a heat conduction cylinder. The heat conduction cylinder in the embodiment of the present invention is a hollow regular hexagonal prism 12 . The prism 12 has six equal-sized rectangular outer walls 120 and a cylindrical inner wall (not shown). The inner wall encloses a cylindrical opening 122 located in the middle of the radiator 10 and extending left and right. Two ring-shaped connecting parts 14 protrude horizontally outward from the left and right sides of the radiator 10, wherein each connecting part 14 is coaxial with the opening 122 of the prism 12, and its inner diameter is equal to the diameter of the inner wall of the prism 12, Its ...

Abstract

The invention discloses an LED light fitting, comprising a radiator and a plurality of LED modules. The radiator comprises a heat-conducting tube and a plurality of fins bonded on the heat-conducting tube; the heat-conducting tube has a through hole; the modules are bonded around the outer wall of the heat-guiding tube; each fin has a first fin part extending outward from the outer wall of the heat-conducting tube and a second fin part extending inward from the inner wall of the heat-conducting tube, and the second fin parts are interconnected. Compared with the prior art, the LED light fitting has the advantages of high radiating efficiency and sound lighting effect.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp with a cooling device. Background technique [0002] As an efficient light source, light-emitting diodes have been increasingly used in various fields. However, a large amount of heat is generated when the light-emitting diodes are working. If the heat is not dissipated in time, the light-emitting diodes may be overheated, resulting in a decrease in luminous efficiency. [0003] A traditional LED lamp includes a plate-shaped radiator and several LEDs mounted on one side of the radiator. These light emitting diodes are evenly arranged on several straight lines. When the light-emitting diode is turned on, the heat generated by it is dissipated into the surrounding air through the radiator. [0004] However, due to the high heat generation of LEDs, in order to dissipate the heat in time, the volume of the radiator is generally made larger to obtain a larg...
