The specific embodiment
Technical problem, technical scheme and the advantage that will solve for the embodiment that makes the utility model are clearer, will combine accompanying drawing and specific embodiment to be described in detail below.
The embodiment of the utility model provides a kind of module backlight and display unit to the poor problem of heavy industry property of module backlight in the prior art, perfect heat-dissipating, and assembly and disassembly is simple, and heavy industry property is good.
Fig. 2 is the structural representation of backboard of the module backlight of the utility model, and as shown in Figure 2, the backboard 6 of present embodiment comprises the U type structure 7 in order to the fixed light bar, and further, backboard 6 also comprises the L type structure 8 in order to lightguide plate fixing.
Fig. 3 is the structural representation of the module backlight of the utility model, and is as shown in Figure 3, and the module backlight of present embodiment comprises backboard 6, be arranged on the LGP 5 on the backboard 6 and be arranged on the lamp bar of LGP 5 sides.Be illustrated in figure 4 as the schematic perspective view of the module backlight of the utility model, can find out, U type structure 7 and 8 positions that are present in lamp bar two ends of L type structure of backboard 6 by Fig. 4.Wherein, the lamp bar is connected with backboard 6 engagings through U type structure 7.Can save a fixedly adhesive tape of usefulness like this,, make that the assembly and disassembly of module backlight is more simple with respect to traditional handicraft; And when module backlight is disassembled, can not destroy the structure of module backlight, the situation of scrapping after adhesive tape is pulled down in the prior art can not occur, make that the heavy industry property of module backlight is better.
Further, backboard 6 can be metal backing, specifically can be aluminium material.In the present embodiment, as shown in Figure 3, a side of lamp bar directly contacts with backboard 6.There is not the obstruct of adhesive tape like this between lamp bar and the backboard 6; The heat that can fast and effeciently light source be produced conducts to backboard 6 surfaces; And through whole back plate 6 heat is distributed, can effectively reduce the temperature of light source and entire aphototropism mould, improve the radiating efficiency of module backlight; Avoid causing defectives such as light source life reduction, the service life of having improved light source and entire aphototropism mould because of light source place temperature is too high.
Further, like Fig. 3 and shown in Figure 4, the lamp bar comprises with backboard 6 vertically disposed pcb boards 3 and is arranged on the LED4 on the pcb board 3.Wherein, a side of pcb board 3 directly contacts with backboard 6, can the heat that LED produces be conducted to backboard 6 surfaces, and through whole back plate 6 heat is distributed.
Particularly, the width of U type structure 7 is not less than the width of pcb board 3.During greater than the width of pcb board 3, can be filled with Heat Conduction Material in the space between pcb board 3 and the U type structure 7, at the width of U type structure 7 to guarantee that the heat that LED produces is conducted to backboard 6 surfaces through this Heat Conduction Material.
Further, like Fig. 3 and shown in Figure 4, also include L type structure 8 on the backboard 6 in order to lightguide plate fixing 5; L type structure 8 is connected with U type structure 7; Like Fig. 3 and shown in Figure 4, L type structure 8 and U type structure 7 shared limits, LGP 5 is connected with backboard 6 engagings through L type structure 8.Can locate LGP 5, ease of assembly through backboard 6 structures own like this.
The module backlight of the utility model at first was stuck in the lamp bar in the U type structure 7 of backboard 6 in when assembling, utilized the structure fixed light bar of backboard 6 itself, afterwards LGP 5 was fastened in the L type structure 8 of backboard 6, accomplished assembling.The structures that the utility model makes full use of backboard 6 itself fix lamp bar and LGP 5, make the simplifying the structure of module backlight to help assembling production.
