Abstract
The utility model provides a kind of CSP lamp bars of light leakage, including substrate, CSP light sources, light-blocking structure, and the CSP light sources, light-blocking structure are respectively provided on the substrate, and the light-blocking structure is arranged in the both sides of the CSP light sources.The CSP lamp bars of light leakage provided by the utility model, can prevent light leakage, improve the brightness of lamp bar.
Description
Technical field
The utility model is related to a kind of CSP lamp bars of light leakage, belong to LED technology field.
Background technology
Light emitting diode (LED) light source has the advantages that high efficiency, long-life, without harmful substances such as Hg, with LED
The fast development of technology, the performances such as brightness, the service life of LED are obtained for great promotion, therefore, nowadays light emitting diode
(LED) light source has begun to be widely used in the backlight technology field of LCD screen.It is in LCD screen according to LED backlight
Position be divided into two kinds of structures of straight-down negative and side entering type.So-called side entering type structure, specifically：LED grain is configured in liquid crystal display
The light emitted from screen edge when LED backlight module being allowed to shine, is penetrated light guide plate by the edge of curtain, then light guide plate of arranging in pairs or groups
The region for being transported to center Screen is gone.
With the fast development of LED backlight technology, demand day of the consumer to LED television superthin structure etc. is cumulative
Add.Currently, in LED backlight technical field, CSP backlighting schemes are mainly used, currently, there are mainly two types of modes：
(1) side entrance back directly is done using the luminous CSP in five faces, but there are leakage problems, cause visual effect bad, brightness
It is relatively low；
(2) reflective plastic block is added in said structure, cost is too high, and installation is inconvenient.
Utility model content
Based on the above deficiency, the technical problem to be solved by the present invention is to provide a kind of CSP lamp bars of light leakage, can
Light leakage is prevented, the brightness of lamp bar is improved.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of CSP lamp bars of light leakage, including substrate, CSP light sources, light-blocking structure, the CSP light sources, light-blocking structure are equal
On the substrate, the light-blocking structure is arranged in the both sides of the CSP light sources for setting.
The CSP light sources are at least one, and formation CSP light source groups on the substrate are arranged in straight line spacing.
The light-blocking structure includes the strip box dam glue for being separately positioned on the CSP light sources group both sides.
The box dam glue is arranged in parallel with the CSP light sources group.
The box dam glue is white.
Further include block, the block setting on the substrate, is highly higher than the CSP light sources.
The dog height is higher than the CSP light sources 0.1mm-0.3mm.
The CSP light sources are the luminous CSP light sources in five faces.
The material of the substrate is copper, aluminium, FR4 or CEM3.
The CSP light sources are affixed on using SMT techniques on the substrate.
Using above technical scheme, the utility model achieves following technique effect：
(1) in the both sides of CSP light sources, setting light-blocking structure stops that light is leaked out from both sides, and can improve brightness.
(2) light-blocking structure is box dam glue, not only can be by light blocking, but also can will be emitted to the light reflection of both sides to just
Face, and material and process costs are low；
(3) box dam glue is white, and reflectivity reaches 85% or more, effectively the light reflection of CSP light sources both sides can be gone out.
(4) block makes its failure for preventing light guide plate expanded by heating to be expressed to CSP light sources.
Description of the drawings
Fig. 1 is the front view of the CSP lamp bars of the utility model light leakage；
Fig. 2 is the vertical view of the CSP lamp bars of the utility model light leakage.
Specific implementation mode
As shown in Figure 1, the utility model provides a kind of CSP lamp bars of light leakage, including substrate 1, CSP light sources 21, gear
Photo structure, the CSP light sources 21, light-blocking structure are arranged on the substrate 1, and the light-blocking structure is arranged in the CSP light
The both sides in source 21.
Wherein, the material of substrate 1 is copper, aluminium, FR4 or CEM3.CSP light sources 21 are affixed on using SMT techniques on substrate 1, are risen
To electrical connection and cooling effect.CSP light sources 21 are five face illuminating source of cuboid, to exempt to encapsulate flip LED light source.CSP
Light source 21 is at least one, and straight line spacing is arranged and forms CSP light sources group 2 on substrate 1.Light-blocking structure is that setting exists
The strip box dam glue 3 of 2 both sides of CSP light sources group can stop that light leaks out.3 parallel CSP light sources group 2 of box dam glue is arranged.Box dam glue
3 be white, and reflectivity reaches 85% or more, can be effectively by the light reflection of 21 both sides of CSP light sources to front.
Further include block 4, the block 4 is arranged on the substrate 1, and height is slightly above CSP light sources 210.1mm-
0.3mm is affixed on lamp bar left, center, right different location, for preventing CSP light sources 21 from being squeezed by light guide plate, gets protection CSP light sources 21
Effect.Block 4 is the rectangular member made of copper sheet, FR4 or other materials.
Finally it should be noted that：The preferred embodiment that these are only the utility model, is not limited to this practicality
It is novel, although the utility model is described in detail with reference to embodiment, for those skilled in the art, according to
So can be with technical scheme described in the above embodiments is modified, or which part technical characteristic is equally replaced
It changes, but within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all include
It is within the protection scope of the utility model.
