Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art.

[0034] Traditional heat sink, for the overall structure, such as Figure 1 Among them, only the convection channel in the Z direction is unblocked, and it is blocked by its own radiator in the X and Y directions, and the utilization rate of the entire internal heat dissipation space is low, resulting in a heavy radiator and poor heat dissipation effect.

[0035] The application of the combined discontinuous multi-layer three-dimensional heat dissipation structure of the present invention on vertically installed lamps, as shown in Figure 2, has excellent convection channels in the three directions of X, Y, and Z, as shown in Figure 3, Make full use of the heat dissipation space, which consists of heat dissipation surface I, heat dissipation surface II, heat dissipation surface III, hea...

Abstract

The invention relates to the technical field of LED (Light Emitting Diode) lamps and particularly relates to a combined discontinuous multilayer three-dimensional heat-radiating structure of an LED lamp device. The combined discontinuous multilayer three-dimensional heat-radiating structure is characterized in that the LED heat-radiating structure is connected with an LED substrate and is the combined discontinuous multilayer three-dimensional heat-radiating structure which consists of a plurality of independent heat-radiating fin module groups, and a cavity exists between every two adjacent independent heat-radiating fin module groups. Compared with the prior art, the combined discontinuous multilayer three-dimensional heat-radiating structure of the LED lamp device has the advantages that the weight is light, the effective heat-radiating area is large, various shapes can be formed through combining, the heat of LED heat sources is directly radiated nearby by using a plurality of independent heat-radiating modules and divided and conquered, and the LED heat sources are independent of one another.

Description

[technical field] [0001] The invention relates to the technical field of LED lamps, in particular to a combined discontinuous multi-layer three-dimensional heat dissipation structure of LED lamps. [Background technique] [0002] As we all know, LED lamps are becoming more and more popular. Whether it is large-scale outdoor display or home lighting, LED lamps are inseparable. However, large LED lamps often have too short life due to excessive heat. So far, LED lamps The heat dissipation of the computer is mainly devoted to four aspects: using high-quality power supply, using a heat sink with good performance, expanding the heat dissipation area, and paying attention to the transmission of heat dissipation. [0003] For conventional LED lamps, for the convenience of processing technology, the radiator is an integral structure, using aluminum extrusion and aluminum casting and other processes. In order to meet the heat dissipation requirements, it is often used to increase the ...
