Description

The LED LGP

Technical field

The utility model relates to the LED LGP, refers to that especially a kind of circuit board contact by electrically conductive ink and circuit board joins, and carries out the transmission between circuit board, to save the layout of electric wire, reaches the function of electric wire conduction simultaneously, to improve the LED LGP of product fine rate.

Background technology

Referring to shown in Figure 1, at present, general common LED LGP, comprise a LGP assembly 1, circuit board 2 and electric wire 22, wherein, these LGP assembly 1 both sides respectively are provided with a circuit board 2, this LGP assembly 1 is by diffusion barrier 11,13 3 layers of leaded light acrylic plate 12 and reflector plates form, each circuit board 2 is provided with a LED21, provides the light source of leaded light acrylic plate 12 by each LED21, moreover, the circuit board 2 of these LGP assembly 1 both sides, must connect by electric wire 22, can make the LED21 of each circuit board 2 obtain power supply, cross over this LGP assembly 1 because of this electric wire 22 and be connected with the circuit board 2 of its both sides, this electric wire 22 is exposed to outside the LGP assembly 1, not only can pull, and cause this electric wire 22 fractures, cause the raising of product fraction defective because of producing in carrying or the assembling process, and must fix by fixed mechanism between this electric wire 22 and the LGP assembly 1, because setting up of this fixed mechanism not only can increase the cost of product, more can increase the time of assembling.

Summary of the invention

Main purpose of the present utility model is to provide a kind of avoiding to pull the problem that ruptures because of electric wire, can save the fixed mechanism between electric wire and the LGP assembly again, to reduce product cost, improves product percent of pass, reduces the assembling LED LGP in man-hour.

The purpose of this utility model is achieved in that a kind of LED LGP, comprises a LGP assembly and a circuit board; This LGP assembly is made up of diffusion barrier, leaded light acrylic plate and reflector plate, and the two ends of this leaded light acrylic plate are respectively equipped with circuit board, and each circuit board one end is provided with a circuit board contact; It is characterized in that:

A this circuit board contact and an electrically conductive ink join, and the circuit board electricity is connected to power supply; This electrically conductive ink is printed in the inboard of diffusion barrier with the printing-type circuit, and joins with the circuit board contact of circuit board, and electric power is conducted between circuit board.Wherein:

Described electrically conductive ink is printed in the inboard of reflector plate with the printing-type circuit, and joins with the circuit board contact of circuit board, and electric power is conducted between circuit board.

Between described electrically conductive ink and circuit board contact, can adopt conduction double faced adhesive tape or anchor clamps or other bonding agent to be fixed.

Advantage of the present utility model is: owing to adopt electrically conductive ink to replace electric wire to carry out the conduction of electricity, not only can avoid the LED LGP in carrying or assembling process, the problem that ruptures owing to pullling of electric wire, can improve simultaneously the qualification rate of product, save the fixed mechanism between electric wire and the LGP assembly, to reduce the cost of product, reduce the man-hour of assembling.
