Detailed Description
Embodiments of the present invention will be described in detail below with reference to fig. 2 to 8.
Examples
The utility model provides a straight following formula LED backlight unit structure, includes structure backplate 4, straight following formula LED lamp strip 2 and heating panel 1, sets up the opening of dodging straight following formula LED lamp strip on the structure backplate 4, and 1 one side of heating panel is fixed with straight following formula LED lamp strip 2, through being fixed in the heating panel on the structure backplate, makes straight following formula LED lamp strip set up in the opening part of structure backplate, accomplishes the installation of straight following formula LED lamp strip.
As shown in fig. 2-8, specifically, the structural back plate is provided with a plurality of connecting bolts 5, the plurality of connecting bolts are uniformly arranged on the upper and lower sides of the opening, in this embodiment, one structural back plate is provided with two openings, and the upper and lower sides of each opening are provided with five connecting bolts for connecting two heat dissipation plates; the upper and lower mounting hole that is provided with corresponding with a plurality of connecting bolt on the heating panel, through pressing close to the structure backplate with the heating panel that will be fixed with straight following formula LED lamp strip to make the connecting bolt of structure backplate pass the heating panel mounting hole that corresponds, rethread hexagon bolt 7 and 5 threaded fixation of connecting bolt, thereby be fixed in the heating panel on the structure backplate, accomplish the installation of heating panel and straight following formula LED lamp strip simultaneously.
