Description of drawings
Fig. 1 is the schematic cross-section of LED lamp bar of the present utility model;
Fig. 2 is the perspective view of LED lamp bar of the present utility model.
Among the figure: 1, bar shaped protective trough; 2, PCB lamp plate; 3, drive IC integrated package; 4, light-passing board; 5, LED lamp pearl; 6, chute; 7, projection; 8, heat-conducting glue; 9, bar shaped framework.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 2, a kind of LED lamp bar of present embodiment comprises bar shaped framework 9, PCB lamp plate 2, drive IC integrated package 3 and light-passing board 4; On the described bar shaped framework 9 bar shaped protective trough 1 is set, opening one side of this bar shaped protective trough 1 arranges described light-passing board 4 and forms a containing cavity, described PCB lamp plate 2 is installed in the containing cavity, this PCB lamp plate 2 is simultaneously installed LED lamp pearl 5 towards light-passing board, and PCB lamp plate 2 light-passing board 4 one sides is dorsad installed described drive IC integrated package 3.LED lamp bar of the present utility model is provided with bar shaped protective trough 1, and PCB lamp plate 2 is installed in this bar shaped protective trough 1, uses light-passing board 4 that PCB lamp plate 2 is blocked simultaneously, can effectively provide protection to PCB lamp plate 2, prevents that external force is to the infringement of display circuit.
In the present embodiment, the material of described bar shaped protective trough 1 is aluminium section bar, draws the aluminium section bar good heat conductivity, strengthens the heat radiation that shows lamp plate, effectively reduces the temperature of luminescent device, the service life of prolongation device, light; Draw aluminium section bar frivolous, effectively reduce the width of bar shaped protective trough 1, improve the penetrating rate of display screen; Drawing aluminium section bar is a kind of metal material, can improve the anti-electromagnetic-radiation ability of circuit.Certainly, in another embodiment, also can use other metal material, Heat Conduction Material or frivolous material etc.,
In the present embodiment, be respectively equipped with the chute 6 for the described light-passing board 4 of pegging graft on the dual-side of the opening part of described bar shaped protective trough 1, light-passing board 4 can be installed fast, improve throughput rate.
