Described direct-light type LED backlight module support column, wherein, described reinforcement is symmetricly set on the respective side of described prism structure.
Described direct-light type LED backlight module support column, wherein, described reinforcement is the triangle rib, the bottom angle of described triangle rib is 69.4 ± 5 °.
Described direct-light type LED backlight module support column, wherein, the height of described reinforcement and the ratio of described prism structure are 0.15-0.35:1.
Described direct-light type LED backlight module support column, wherein, the diameter of described fillet structure is 2 ± 1 mm.
Described direct-light type LED backlight module support column, wherein, described support column is transparent PC support column or transparent PMMA support column.
Described direct-light type LED backlight module support column, wherein, described reinforcement is 2, is symmetricly set on respectively on the respective side of described prism structure.
A kind of direct-light type LED backlight module comprises backboard and the blooming piece of direct-light type LED backlight module, wherein, is provided with aforesaid direct-light type LED backlight module support column between the backboard of described direct-light type LED backlight module and blooming piece.
Beneficial effect: a kind of direct-light type LED backlight module provided by the utility model and support column thereof, by adopting transparent PC, the PMMA material has solved all kinds of shadow problems that present direct-light type LED backlight module support column faces, and further reduced the formation of shadow by the design of fillet structure, the unlikely damage of blooming piece in the LED-backlit module that fillet structure has also guaranteed to support simultaneously, and, strengthened the intensity of support column by the design of reinforcement, guaranteed that support column has enough mechanical strengths when eliminating shadow.Improved the product yield, reduced production costs indirectly.
Description of drawings
Fig. 1 is the structural representation of direct-light type LED backlight module support column of the present utility model.
The specific embodiment
The utility model provides a kind of direct-light type LED backlight module and support column thereof, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below the utility model further described.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
A kind of direct-light type LED backlight module support column as shown in Figure 1, described support column is arranged between the backboard and blooming piece of direct-light type LED backlight module, its bottom is fixed on the backboard, the claw 200 and the baffle plate 300 that comprise passive prism structure 100 and be arranged on the support column bottom, described claw 200 is sticked in the locating hole of described backboard and the barrier effect of described baffle plate 300 is realized the fixing of support column, and described support column is transparent PC support column or transparent PMMA support column.Solved the problem of the residual shadow of opaque material support column in the prior art with regard to good like this, but the support strength of transparent material support column is generally not high, can causes the whole service life of LED to shorten.Therefore, in described prism structure 100 sides bottom reinforcement 110 is set, described reinforcement 110 is symmetricly set on the respective side of described prism structure 100.But reinforcement 100 is brought into play the maximum intensity booster actions like this, for guaranteeing that support column 100 has the strongest support strength, described reinforcement 110 is designed to be the triangle rib, and the bottom angle a of triangle rib is 69.4 ± 5 °, preferable, the angle of angle a is 69.4 °.The ratio of the height of described reinforcement 110 and described prism structure 100 is 0.15-0.35:1, and preferable is 0.22.Under above-mentioned design standard, reinforcement 110 can provide maximum support intensity, when guaranteeing that support column 100 possesses enough mechanical strengths, also can not influence the overall performance of LED-backlit module, not therefore residual shadow.Preferably, described reinforcement is 2, is symmetricly set on respectively on the respective side of described prism structure.
