Abstract
The utility model relates to the optical lens structure of backlight module lamp bar, comprise optical lens body, optical lens body comprises circular arc end face, annular side and planar base surface, described planar base surface is provided with three pin positions being equilateral triangle and being distributed in the middle part of planar base surface, and the outer peripheral maximum distance of any two pin positions is 12mm.Compared with pin position being arranged in prior art the mode of edge, reduce the area that required pcb board installed by optical lens, thus reduction production cost, simultaneously the outer peripheral maximum distance of any two pin positions is the LED chip that the some glue of 12mm when can guarantee that optical lens is installed does not affect on pcb board, guarantees the quality of the backlight module lamp bar of production.
Description
Technical field
The utility model relates to backlight module lamp bar technical field, is specifically related to the optical lens structure of backlight module lamp bar.
Background technology
At present, in the field of backlight module lamp bar, the production cost of backlight module lamp bar remains high, and the market price of lamp bar keeps dropping due to market saturation, thus causes the producer of a lot of backlight module lamp bar to be difficult to effectively commercial, has difficulty in taking a step.In order to break through this quagmire, the producer of many production backlight module lamp bars starts with from reduction production cost one after another.The large cost producing backlight module lamp bar is then applied on the PCB raw material of lamp bar, the producer of backlight module lamp bar is in order to reduce the PCB cost of raw material of lamp bar, and the mode of employing comprises following two kinds: 1, adopt one side to cover copper to PCB and replace original double-sided copper-clad; 2, CM-1PCB sheet material matter is adopted to replace FR4 material.But above-mentioned employing one side covers the mode of copper, poor thermal conductivity, and crossed Reflow Soldering in volume production process after, pcb board, due to two sides stress difference, easily occurs to tilt distortion, directly affects the quality of product; Adopt CM-1 material as pcb board, make the poor thermal conductivity of pcb board, thermal stress poor, easily occur that the fire-retardant value of UL can not meet the demands, and the coefficient of expansion is large, easily cause pcb board at high temperature easy aging distortion, and then affect the effect of LED chip laminating, thus directly affect the quality of product.
Obviously, lose more than gain in the mode reducing production cost as cost to sacrifice product quality, can not tackle the problem at its root.
Utility model content
The purpose of this utility model overcomes shortcomings and deficiencies of the prior art, there is provided a kind of optical lens structure of backlight module lamp bar, its pin position is arranged on bottom surface, and the distribution in equilateral triangle, reduce the area that required pcb board installed by optical lens, thus reduce production cost.
The purpose of this utility model is achieved through the following technical solutions:
The optical lens structure of backlight module lamp bar, comprise optical lens body, optical lens body comprises circular arc end face, annular side and planar base surface, described planar base surface is provided with three pin positions being equilateral triangle and being distributed in the middle part of planar base surface, and the outer peripheral maximum distance of any two pin positions is 12mm.
Particularly, the center of three pin positions of described planar base surface and the center superposition of planar base surface.
The utility model comprises following advantage and beneficial effect compared to existing technology:
The utility model is by arranging three pin positions being equilateral triangle and being distributed in the middle part of planar base surface at planar base surface, and the outer peripheral maximum distance of any two pin positions is 12mm, compared with pin position being arranged in prior art the mode of edge, reduce the area that required pcb board installed by optical lens, thus reduction production cost, simultaneously the outer peripheral maximum distance of any two pin positions is the LED chip that the some glue of 12mm when can guarantee that optical lens is installed does not affect on pcb board, guarantees the quality of the backlight module lamp bar of production.
Accompanying drawing explanation
Fig. 1 is the optical lens structure schematic diagram of backlight module lamp bar in embodiment;
Fig. 2 is the side view of the optical lens of backlight module lamp bar in embodiment.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1 and Figure 2, the optical lens structure of backlight module lamp bar, comprise optical lens body 1, optical lens body comprises circular arc end face 11, annular side 12 and planar base surface 13, described planar base surface is provided with three pin positions (131 being equilateral triangle and being distributed in the middle part of planar base surface,, and the outer peripheral maximum distance of any two pin positions is 12mm 132,133).As the preferred embodiment of the present embodiment, the center of three pin positions of described planar base surface and the center superposition of planar base surface.For this optical lens structure, the width of the pcb board of its correspondence can be reduced into and be not less than 12mm, compared with the diameter of optical lens annular side must being not less than with the width installing pcb board needed for optical lens in prior art, needed for the optical lens that installation the utility model provides, the width of pcb board reduces greatly, and the cost therefore adopting this light show lens arrangement to produce needed for backlight module lamp bar also reduces greatly.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (2)
