Abstract

The utility model discloses a LED array module capable of being connected quickly and an LED lamp formed by the same. The LED array module includes a PCB, a plurality of LED chips welded on the front surface of the PCB, and at least four sockets of which the jacks are outwards welded on the back surface of the PCB. The LED array module is characterized in that the PCB is a square-shaped structure; the sockets are arranged at the peripheries of the four edges of the PCB; and corresponding pins of each socket are electrically connected with each other through the PCB. One LED array module can be connected with the sockets on another LED array module through straight-foot pins or right-angle pins, such that the LED array modules can be expanded in four directions. The LED array modules can be expanded in a plane direction through the straight-foot pins, and can be expanded in a vertical plane through the right-angle pins; when the LED array modules are expanded, the sockets on the LED array modules not only enable connection and fixation, but also enable electrical connection between modules; and therefore, the LED array modules can be spliced with each other to form various patterns and characters through expansion without additional connection of a power source wire required, so the LED array module is convenient and fast in usage, and is applicable to on-site manufacture of LED lamps.

Description

A kind of led array module that can fast connect reaches by its LED lamp of forming

Technical field

The utility model relates to the LED lighting field, the LED lamp that relates in particular to a kind of led module and be formed by connecting by this led module.

Background technology

In existing LED lighting field, the light fixture that is constituted by LED particularly, led chip is wherein generally arranged module according to certain rules and is fixedly made illuminating lamp on the lamp holder, and perhaps led chip is arranged in the literal module or pattern module is made advertising lamp.Because these light fixtures all are finished products, the back user of dispatching from the factory changes led chip or changes its spread geometry very inconvenient.For example, the user makes the LED advertising lamp, must make producer's customization of LED light fixture to specialty, has so just raised its manufacturing cost inevitably.Hence one can see that, and led module of the prior art exists assembling to lack flexibility, and expansibility is poor, is unfavorable for the LED lamp of the various styles of user's field fabrication.

Summary of the invention

The problems referred to above that the utility model exists at existing led module, and propose that a kind of expansion is good, the LED lamp that can be assembled into various styles flexibly, and the led module that can fast connect.

For achieving the above object, the scheme that the utility model is taked is: a kind of led array module that can fast connect, comprise PCB, the some led chips that are welded on the PCB front, it is characterized in that: further comprising the socket that at least 4 its jacks are welded on the PCB back side outwardly; Described PCB is square structure, and described socket is located at the marginal position on PCB four limits, and the corresponding pin of each socket electrically connects by PCB.

The led array module connects socket on it by pin contact pin or right angle contact pin, and the led array module can be expanded to four direction.Just can expand to the plane by the pin contact pin, by the right angle contact pin, then can expand to vertical plane.What deserves to be explained is that when the led array module was expanded, socket not only played the effect of being connected and fixed on it, also plays intermodule simultaneously and is electrically connected effect, can carry electric current.Therefore, this led array module can be spliced into various figures or literal by expanding, and does not need to connect in addition power line, and is very easy to use quick, is applicable to the LED lamp of the various styles of field fabrication.

Further, the error-polarity connection of power supply when connecting for fear of socket, described socket are the single socket with 4 round jacks, and two pins in the centre of single socket electrically connect by PCB, and two other pin also electrically connects by PCB.Therefore, no matter polylith led array intermodule is just connecing or reversal connection, power supply can not occur causing short circuit phenomenon on the contrary because polarity connects.

Preferably, described socket is set in the centre position at edge, PCB four limit in twos symmetrically.

Be convenient heat radiation, described PCB is provided with the through hole that several diameters are 3mm ~ 5mm.This through hole can also the double as installing hole.

According to different situations, the arrangement of led chip on PCB can have various, as: as described in led chip be 4, the array structure with 2 * 2 is distributed on the PCB.Described led chip is 9, and the array structure with 3 * 3 is distributed on the PCB.Described led chip is 16, and the array structure with 4 * 4 is distributed on the PCB.

As the application special case of above-mentioned led array module, a kind of LED lamp is characterized in that: it is connected into cube structure by at least 6 foregoing led array module spliced, and led array intermodule adjacent one another are is provided with pin contact pin or the right angle contact pin that connects its socket.

The quantity of the quantity of led array module depends primarily on the electric current that the printing copper sheet can pass through among the load-bearing limit of plug and the PCB.The quantity of led array module is more big, and it is long-pending also just more big that it splices the LED lamp body, and its brightness is also more big.Preferably, the quantity of described led array module is 24 or 54.

In addition, above-mentioned led array module also can be assembled into literal or other pattern.

From the above mentioned as can be known, the utility model has the advantages that: simple in structure, make easily; Expansion is good, connection is quick, assembling is flexible, makes things convenient for field fabrication, and the user need not also can connect the LED lamp of piecing together various styles voluntarily quickly through professional manufacturing factory, thereby has reduced the cost of manufacture of LED lamp.Because the led array module has and splices performance flexibly, therefore, can be used for fields such as intention illumination or advertising signboard.
