Embodiment Construction

[0044] The present invention will be further elaborated below in conjunction with accompanying drawings, and its shape and structure can be realized by those skilled in the art.

[0045] The traditional MR16 LED lamp is composed of an external radiator or an internal radiator (in this example, a cooling cup 17 is selected), a lens 18, an LED display board 19, a lamp interface and a power supply box 20. Figure 4 Connect and install as shown, the heat dissipation part is as follows Figure 5 As shown, fan-shaped heat sinks surround the heat dissipation cup 17 at equal intervals, and the heat dissipation area formed is: (heat dissipation surface 21 + heat dissipation surface 22 + heat dissipation surface 23 + heat dissipation surface 24 + heat dissipation surface 25) * 18 = 6500 square millimeters, traditional heat dissipation Inside the device such as Image 6 The cavity shown is solid or the power supply is placed, which cannot be used, resulting in uneven heat dissipation of...

Abstract

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.

Description

[technical field] [0001] The invention relates to the technical field of manufacturing LED lamps, in particular to a combined three-dimensional heat dissipation structure for LED lamps that fully utilizes the heat dissipation space. [Background technique] [0002] With the increasing popularity of LED lamps, both large-scale outdoor displays and home lighting are inseparable from LED lamps, and LED lamps often affect reliability due to heat dissipation problems, and the brightness cannot meet the requirements of traditional lamps, so they cannot directly replace traditional lamps. Lamps, such as 50W MR16 halogen lamps, can output warm white temperature 2700K 610LM luminous flux, while the same MR16LED lamps can only reach half the brightness of traditional halogen lamps; 150W traditional PAR38 halogen lamps can output warm white temperature 2700K 2000LM luminous flux, LED PAR38 Lamps often do not exceed 1000LM luminous flux output. [0003] Conventional LED lamps, due to pr...
