Abstract
The utility model discloses a kind of LED light bar with pantoscopic lens and backlight module, and wherein LED light bar includes：Wiring board, some LEDs being welded on the wiring board and the lens being enclosed within the LED, the lens are the lens that lighting angle is 170 °, and the lens-shape is concavees lens.The utility model is equipped with the scheme of the lens of 170 ° of big lighting angle by using LED, the scope of light irradiation is bigger, dark space will not be also produced even if the distance between increase lens and lens or the distance between lamp bar and lamp bar, so as to save the quantity of lens and lamp bar, cost is reduced；In addition, LED uses high-powered LED lamp, so for the occasion higher to brightness requirement, the lamp bar and backlight module that the utility model is provided can meet demand.
Description
Technical field
The utility model is related to field of semiconductor illumination, more particularly to a kind of LED light bar and the back of the body with pantoscopic lens
Optical mode group.
Background technology
LED is referred to as forth generation lighting source or green light source, the features such as with energy-saving and environmental protection, long lifespan, small volume,
Therefore it is widely used in every field.Lens can carry out secondary light-distribution to LED light source, light fixture is met specific light intensity point
Cloth requirement, strengthens the service efficiency and luminous efficiency of light.The lighting angle angle of existing LED is generally less than 160 °, arrangement
Spacing can not be excessive in lamp bar, otherwise can produce dark space, therefore, when the timing of lamp bar length one, required LED quantity compared with
Many, cost is larger.Equally, it is certain luminous because lighting angle is narrower when being applied using the lamp bar of the LED to backlight module
The quantity of lamp bar needed for area is more, and cost is larger.
Therefore, the prior art is defective, it is necessary to improve.
Utility model content
The technical problems to be solved in the utility model is：A kind of LED light bar and backlight mould with pantoscopic lens are provided
Group so that divergence of beam, can expand the spacing between lens and lens.
To achieve the above object, a kind of LED light bar with pantoscopic lens of the utility model offer, including wiring board,
Some LEDs being welded on the wiring board and the lens being enclosed within the LED, the lens are that lighting angle is
170 ° of lens.
Further, the lens are concavees lens.
Further, the spacing distance between adjacent lens and lens is equal.
Further, the wiring board is FPC.
Further, connected mode of some LEDs in the LED light bar is to be connected in series.
Further, connected mode of some LEDs in the LED light bar is to be connected in parallel.
Further, the LED is high-powered LED lamp.
The utility model also provides a kind of backlight module, including some LED light bars, and the lamp bar includes：Wiring board,
Some LEDs being welded on the wiring board and the lens being enclosed within the LED, the lens are saturating for 170 ° of wide-angle
Mirror.
Further, connected mode of some lamp bars on the backlight module is to be connected in parallel.
Further, the interval between the adjacent LED light bar is equal.
Using such scheme, the utility model is equipped with the scheme of the lens of 170 ° of big lighting angle by using LED,
The scope of light irradiation is bigger, also will not even if the distance between increase lens and lens or the distance between lamp bar and lamp bar
Dark space is produced, so as to save the quantity of lens and lamp bar, cost is reduced；In addition, LED uses high-powered LED lamp, so
For the occasion higher to brightness requirement, the lamp bar and backlight module that the utility model is provided can meet demand.
Brief description of the drawings
Fig. 1 is the structural representation of LED light bar.
Fig. 2 is the illumination effect figure of backlight module.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of LED light bar 1 with pantoscopic lens, including wiring board 3, welding
In some LEDs 4 on the wiring board and the lens 2 being enclosed within the LED 4.The wiring board 3 is flexible circuitry
Plate, the lens 2 are the lens that lighting angle is 170 °, and the lens 2 are concavees lens, have disperse function to light.Adjacent lens 2
Spacing distance between lens 2 is equal, and connected mode of some LEDs 4 in lamp bar is to be connected in series or company in parallel
Connect.The utility model is equipped with the scheme of the lens 2 of 170 ° of big lighting angle using LED 4, and LED 4 is issued with low-angle
Light by lens 2 diverging after, become the good light source of wide-angle, uniformity and launch, accordingly even when expand lens 2 between
Distance, LED 4 and the quantity of lens 2, will not also produce dark space, both ensure that luminous in the lamp bar to reduce certain length
Uniformity, production cost can be reduced again.
In addition, LED 4 can use high-powered LED lamp, for the occasion higher to brightness requirement, the lamp bar can also
Demand is met well.
Referring to Fig. 2, the utility model also provides a kind of backlight module, including some LED light bars 1, dashed region
Light-emitting zone 5 is represented, the connected mode of some lamp bars is is connected in parallel, and the spacing between adjacent lamp bar and lamp bar is equal.
The backlight module can apply to the places such as the backlight of advertisement, and it uses the lamp bar with big lighting angle, can expand lamp bar
The distance between with lamp bar, to reduce the usage quantity of lamp bar, production cost is reduced, dark space will not be also produced.
In summary, the utility model is equipped with the scheme of the lens of 170 ° of big lighting angle, light by using LED
The scope of irradiation is bigger, will not also be produced even if the distance between the distance between increase lens and lens or lamp bar and lamp bar
Dark space, so as to save the quantity of lens and lamp bar, reduces cost；In addition, LED uses high-powered LED lamp, so for
The occasion higher to brightness requirement, the lamp bar and backlight module that the utility model is provided can meet demand.
Preferred embodiment of the present utility model is these are only, the utility model is not limited to, it is all in this practicality
Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
