Description

Technical Field

[0001] The utility model relates to the technical field of lamp board heat dissipation structures, in particular to a structure for improving the heat dissipation efficiency of a direct-type backlight LED lamp board. Background Art

[0002] Existing conventional direct-type backlight LED lamp panels are all installed in a structural frame with a metal base plate. The LED lamp panel is in direct contact with the metal base plate structure. The heat generated during operation is transferred to the metal base plate structure, and then dissipated outward through the metal base plate structure, thereby achieving the effect of cooling the LED lamp panel. However, in order to increase the strength of some metal base plate structures, an external convex mold design is made, resulting in a corresponding concave area inside, causing the LED lamp panel to be unable to completely contact the metal base plate, and some areas are suspended in the air, resulting in very low heat dissipation efficiency. In addition, some flat metal base plate structures cannot be completely flat due to the strength of the metal itself, which has a certain impact on the heat dissipation efficiency of the LED lamp panel. If the heat dissipation effect is not ideal, the service life of the LED lamp beads will be reduced.

[0003] Therefore, to address this problem, there is a need for an improved structure that improves the heat dissipation efficiency of a direct-type backlight LED lamp panel. Utility Model Content
