Abstract (en)

[origin: EP2899459A1] The present invention relates to the technical field of LED lamp manufacturing, more particularly to an LED lamp combined three-dimensional radiating structure with full use of radiating space. The LED lamp combined three-dimensional radiating structure is formed by combining an external radiating body with an internal radiating body, the bottom of the internal radiating body is connected with an LED display panel, the top of the external radiating body is connected with a lamp interface and power supply box, a combined and discontinuous multilayer three-dimensional radiating structure consisting of a plurality of radiating fins is disposed on the top of the internal radiating body, and a hollow cavity is formed between the adjacent radiating fins. In the present invention, the combined three-dimensional radiating structure is employed at the center with the most concentrated heat, thus increasing the total radiating area, maximizing the effective radiating area and effectively solving the defects like low utilization rate of radiating space and non-permeable internal space structure; in addition, compared with traditional LED lamps, both the radiating effect and the output brightness are doubled.
