Abstract
The utility model discloses kind of a down straight aphototropism mode set lamp bar, it relates to lamp bar technical field.Surface-mount LED lamp pearl (2) welds the surface being attached to pcb board (1) in array, ((4) are together in series or parallel the circuit on pcb board (1) surface, lens (3) are attached to LED lamp bead (2) top, form a cavity volume (6) with pcb board (1), the territory, face that cavity volume (6) is mapped to pcb board (1) place is pasted with COB minute surface aluminium lamination (5).It can overcome the drawback of prior art, reasonable in design is novel, the light that LED lamp bead sends is reflected on the COB minute surface aluminium lamination on pcb board surface, because the reflecting rate of aluminium lamination is up to 95%-98%, so part luminous energy being reflected with peak use rate, relative to traditional solder mask (reflecting rate 60%-90%), the final overall brightness of module the former exceed 10% ~ 15% than the latter, more save cost.
Description
Technical field
The utility model relates to a kind of down straight aphototropism mode set lamp bar, belongs to lamp bar technical field.
Background technology
Under the prerequisite not needing light guide plate, direct-light-type backlight is placed in bottom backboard by LED luminous lamp strip array, and described LED lamp bar has the elements combinations such as pcb board, Surface-mount LED lamp pearl, lens to form, and its principle of luminosity is, the light sent from LED is through the secondary optics effect of lens, part light is reflected away uniformly, some light is surperficial to pcb board by reflection from lens, pcb board surface is coated with solder mask, because the reflecting rate of solder mask used on the market is at present mostly 60% ~ 90%, so part light can not be reflexed in lens to greatest extent and be reflected away by it, after the light dispersing out in final module is evenly penetrated by surperficial diffuser plate and blooming piece, the brightness of overall module will be lost, when module brightness does not reach, improve brightness, just need the brightness increasing LED lamp bead, or increase blooming piece, now, the efficiency of these two the corresponding increase backlights of improvement meeting and cost.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of down straight aphototropism mode set lamp bar.
The utility model down straight aphototropism mode set lamp bar, it comprises pcb board 1, Surface-mount LED lamp pearl 2, lens 3, circuit 4 and COB minute surface aluminium lamination 5, in array, weldering is attached to the surface of pcb board 1 to Surface-mount LED lamp pearl 2, the circuit 4 on pcb board 1 surface is together in series or parallel, lens 3 are attached to above LED lamp bead 2, form a cavity volume 6 with pcb board 1, the territory, face that cavity volume 6 is mapped to pcb board 1 place is pasted with COB minute surface aluminium lamination 5.
Described lamp bar is that array is positioned over bottom module backboard, then coordinates other blooming piece to form backlight.
The beneficial effects of the utility model: it can overcome the drawback of prior art, reasonable in design is novel, the light that LED lamp bead sends is reflected on the COB minute surface aluminium lamination on pcb board surface, because the reflecting rate of aluminium lamination is up to 95%-98%, so part luminous energy being reflected with peak use rate, relative to traditional solder mask (reflecting rate 60%-90%), the final overall brightness of module the former exceed 10% ~ 15% than the latter, more save cost.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 of the present utility modelly faces structural representation;
Fig. 2 is plan structure schematic diagram of the present utility model;
Fig. 3 is the top view being made up of down straight aphototropism mode set the utility model lamp bar.
detailed description of the invention:
As Figure 1-3, this detailed description of the invention is by the following technical solutions: it comprises pcb board 1, Surface-mount LED lamp pearl 2, lens 3, circuit 4 and COB minute surface aluminium lamination 5, in array, weldering is attached to the surface of pcb board 1 to Surface-mount LED lamp pearl 2, the circuit 4 on pcb board 1 surface is together in series or parallel, lens 3 are attached to above LED lamp bead 2, form a cavity volume 6 with pcb board 1, the territory, face that cavity volume 6 is mapped to pcb board 1 place is pasted with COB minute surface aluminium lamination 5.
Described lamp bar is that array is positioned over bottom module backboard, then coordinates other blooming piece to form backlight.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof
