Abstract

The utility model discloses an LED (light emitting diode) conduction module, which comprises a shell, a plurality of LED chips and a PCB (printed circuit board) fixed with an electronic component, wherein the shell is provided with two electric wires. The LED conduction module is characterized by also comprising two conduction screws used for fixedly connecting the PCB and the shell; the LED chips and the PCB fixed with the electronic component are conducted with the anodes and the cathodes of the two electric wires by the two conduction screws to form a conduction loop; the two conduction screws pass through screw hole positions on the PCB and the shell to connect the PCB with the shell; after the conduction screws are rotated to the proper position, the LED chips are enabled to conduct with the electric wires; and the LED chips can light after being connected with an external power supply. The LED conduction module disclosed by the utility model has the advantages of simple structure and convenience in installation, the traditional lead welding conduction mode is omitted due to the screw conduction mode, and the problems of cold joint, desoldering and welding spot oxidation due to module welding are reduced, thereby being favorable for prolonging the service life of the module.

Description

A kind of LED conduction module

Technical field

The utility model relates to the LED technical field, particularly a kind of LED conduction module.

Background technology

The LED module is a kind of light-illuminating that is used for advertising lamp box, label and luminescent characters thereof, and module great majority in the market are to connect lead through welding manner, therefore manufacture craft and attractive in appearance unsatisfactory, thereby influence module outward appearance and productivity effect.

The utility model content

In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of LED conduction module, and connected mode is unique; Removed the step of former welding lead from; Screw rotates the conducting immediately that puts in place, and overall appearance is convenient to assembling, can effectively improve the productivity effect of module.

To achieve these goals, the technical scheme of the utility model is following:

A kind of LED conduction module; The PCB wiring board that comprises housing, plurality of LEDs chip and intrinsic electronic devices and components that two wires are installed; Be characterized in; Also comprise being used for fixing two conduction screws that connect said PCB wiring board and housing, be communicated with the both positive and negative polarity of two wires, constitute a conducting loop through the PCB wiring board of said two conduction screws with said led chip, intrinsic electronic devices and components.

Further, said PCB wiring board is corresponding with the housing junction to be provided with two screw hole positions, and above-mentioned two conduction screw correspondences are passed two screw hole positions and connected the two.Make led chip and electric wire conducting after the rotation of conduction screw puts in place, connecting extraneous power supply just can be luminous, uses simple, convenient.

Said housing is rectangular-shaped, and two wires are injection-moulded in enclosure interior and are connected as a single entity, and is convenient to install.

The beneficial effect of the utility model is; Novel module electrically conducting manner simple in structure, easy for installation, as to adopt the screw spiral to put in place has saved welding step and has connected conduction; Reduce rosin joint, sealing-off and solder joint problem of oxidation that module causes because of welding, further prolonged the service life of module.

It is conducting that the screw rotation puts in place, and overall appearance is convenient to assembling, effectively improves the productivity effect of module.

Be widely used, can be used for the commercial advertisement lamp box, the luminous lighting of label and font thereof.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure, 1, led chip, 2, the PCB wiring board, 3, electric wire, 4, housing, 5, electronic devices and components, 6, the conduction screw, 7, the conduction screw.

The specific embodiment:

For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with specific embodiment.

Embodiment:

Referring to Fig. 1; A kind of LED conduction module; Comprise rectangular shape housing 4, be injection-moulded in two wires 3, PCB wiring board 2 in the housing 4, be attached to a plurality of electronic devices and components 5 and three LEDs chips 1 on the PCB wiring board 2, is connected and the conduction screw 6 of turning circuit effect and the screw 7 that conducts electricity with plaing simultaneously.

As shown in the figure, led chip 1 is selected paster low-power LED chip for use, as the light source of conduction module, and advantages of small volume, easy for installation, it is little to take up room.

Wherein, two

screw hole positions

61 and 71 are set on the PCB wiring board 2, housing 4 also is provided with two screw hole positions in corresponding junction, and conduction screw 6 is fixedly connected on PCB wiring board 2 on the housing 4 with the conduction screw 7 corresponding

screw hole positions

61 and 71 of passing.

Simultaneously; When conduction screw 6 puts in place with 7 rotations of conduction screw; The PCB wiring board 2 of led chip 1, intrinsic electronic devices and components 5 is communicated with the both positive and negative polarity of two wires 3, thereby constitutes a conducting loop, on behalf of anodal electric wire 3, conduction screw 7, conduction screw 6 is communicated with the electric wire 3 of representing negative pole; Perhaps exchange all can realize purpose.

Output through two wires 3 connects extraneous power supply then, makes the conducting of whole loop, and LED conduction module just can be luminous, uses simple.

The utility model structure biggest advantage is the novel module electrically conducting manner that adopts above-described conduction screw spiral to put in place; Save welding step and connected conduction; Reduce rosin joint, sealing-off and solder joint problem of oxidation that module causes because of welding, make that this LED conduction module is more durable, the life-span is long.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
