Abstract
The utility model discloses a kind of straight-down negative LED light bar, LED including pcb board and on pcb board, pcb board includes aluminium base and the thermal insulation layer and copper foil layer that are arranged at from bottom to top on the aluminium base, the pin of LED is welded on the copper foil layer of pcb board, there is the Bu Deng areas and Fei Bu lamps area being alternately arranged successively on pcb board, the side in the Fei Bu lamps area of the pcb board is provided with recess, the side in Bu Deng areas correspondingly forms convex portion, the convex portion in the Bu Deng areas of the recess in Fei Bu lamps area another the straight-down negative LED light bar adjacent with the straight-down negative LED light bar is mutually chimeric with the angle more than 90 degree.The utility model reduces the material of production pcb board, and then reduces the cost of straight-down negative LED light bar.
Description
Technical field
It the utility model is related to straight-down negative LED light bar.
Background technology
As the at full speed of LED backlight market increases several years ago, increasing producer adds this field.Copper etc. simultaneously
The price of heavy metal and other raw materials does not stop to go up, the continuous lifting of labor wage, therefore increasingly swashs in this competition
Strong, in the case of profit more and more thinner, it is imperative to reduce cost.And pcb board is poor in the production of straight-down negative LED light bar now
70% cost is seldom occupied, so the problem of cost of manufacture for how reducing pcb board is to be solved.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of straight-down negative LED light bar, reduces cost.
The technical solution of the utility model is：A kind of straight-down negative LED light bar, including pcb board and the LED on pcb board
Lamp, pcb board include aluminium base and the thermal insulation layer and copper foil layer that are arranged at from bottom to top on the aluminium base, and LED is drawn
Pin is welded on the copper foil layer of pcb board, has the Bu Deng areas and Fei Bu lamps area being alternately arranged successively, the pcb board on pcb board
The side in Fei Bu lamps area be provided with recess, the side in Bu Deng areas correspondingly forms convex portion, recess and the straight-down negative in Fei Bu lamps area
The convex portion in the Bu Deng areas of another adjacent straight-down negative LED light bar of LED light bar is mutually chimeric with the angle more than 90 degree.
The width of the pcb board in the Fei Bu lamps area provided with recess is 5mm.
Ink layer is coated with the copper foil layer of each pcb board.
The utility model proposes straight-down negative LED light bar reduce the material of production pcb board, and then reduce it is single it is straight under
The cost of formula LED light bar；And the mutually chimeric angle of two pcb boards is more than 90 degree, mutually it is fitted together to, carries relative to using right angle
The high utilization rate of pcb board, it is economical and practical；Facilitate the production of pcb board simultaneously, beneficial in pcb board upward wiring.
Brief description of the drawings
Fig. 1 is the structure chart of single straight-down negative LED light bar in the utility model embodiment.
Fig. 2 is the sectional structure chart of pcb board in the utility model embodiment.
Fig. 3 is the schematic diagram that two straight-down negative LED light bars are entrenched togather in the utility model embodiment.
Embodiment
Such as Fig. 1 and Fig. 2, the straight-down negative LED light bar that is provided in the utility model embodiment, including pcb board 10 and located at this
LED 20 on pcb board 10, pcb board 10 include aluminium base 11 and the thermal insulation layer being arranged at from bottom to top on aluminium base 11
12 and copper foil layer 13, the pin of LED be welded on the copper foil layer of pcb board.In order to prevent the copper foil layer of pcb board from aoxidizing, pcb board
Copper foil layer 13 on be coated with ink layer 14.
There is the Bu Deng areas 15 and Fei Bu lamps area 16 being alternately arranged successively such as Fig. 1 and Fig. 3, on pcb board 10, pcb board it is non-
The side in Bu Deng areas 16 is provided with recess, and the side in Bu Deng areas 15 correspondingly forms convex portion, the Fei Bu lamps area of the straight-down negative LED light bar
The convex portion in the Bu Deng areas 15 of 16 recess another the straight-down negative LED light bar adjacent with the straight-down negative LED light bar is mutually chimeric, phase
Mutually chimeric angle a is more than 90 degree, and recess and convex portion are trapezoidal, trapezoidal recess and the shorter base and two of trapezoidal convex portion
The mutually chimeric angle a of two pcb boards of formation between individual side, preferably 120 degree.So reduce the material of production pcb board,
And then reduce the cost of single straight-down negative LED light bar.And the mutually chimeric angle of two pcb boards is more than 90 degree, relative to
It is mutually chimeric using right angle, the utilization rate on pcb board is improved, it is economical and practical；Facilitate the production of pcb board simultaneously, beneficial in PCB
Upward wiring.
Because the line width of electrode line and negative line needs 1mm, while electrode line in the design of the pcb board of straight-down negative LED light bar
Line-spacing between negative line also needs 1mm, and the distance that electrode line and negative line arrive pcb board sideline respectively also will be 1mm.In order to
Ensure the cabling on pcb board, while less material to greatest extent, the width of the pcb board in the Fei Bu lamps area provided with recess is set
It is set to 5mm.
Only to illustrate design of the present utility model, one of ordinary skill in the art's specific embodiment above exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
Claims (3)
