Description

A kind of extendible omnipotent LED template and consisting of three-dimensional LED advertising lamp

Technical field

The utility model relates to the LED lighting field, relates in particular to a kind of extendible LED module.

Background technology

Because the LED power savings is remarkable, generally be used on signboard or advertising lamp.Commonly the matrix display of extendible omnipotent LED template composition shields, but this display screen word or pattern.But this display screen is because the demand motive circuit is complicated, and manufacturing cost is higher, easily is out of order, and the rear maintenance of breaking down is very inconvenient.Easily several ten thousand yuan of prices to units up to a million, allowing much has the user who needs to hang back.

Summary of the invention

The utility model shields for existing expensive matrix display, and proposes a kind of cheap LED module that can conveniently expand connection.

For achieving the above object, the scheme that the utility model is taked is: a kind of extendible omnipotent LED template, comprise PCB, it is characterized in that: extendible omnipotent LED template also comprises the LED receptacle array that is welded on the PCB front, and at least 4 its jacks are welded on outwardly the socket at the PCB back side; Described PCB is square structure; Socket is located at the marginal position on PCB four limits, and the corresponding pin of each socket is electrically connected by PCB; The LED socket of colleague or same column is electrically connected each other by PCB or current-limiting resistance, interlacing or be electrically connected each other by PCB every the LED socket of row, the LED socket of adjacent lines or adjacent columns is electrically connected by PCB with the pin of the opposed polarity of socket respectively by polarity.

With some with the LED device of pin by the polarity crossover on can the adjacent lines or adjacent columns socket of LED module, and be arranged in required pattern or word gets final product.If when an extendible omnipotent LED template can not hold word or pattern content, extendible omnipotent LED template connects socket on it by pin contact pin or corner contact pin, can expand to four direction.Can expand to the plane by the pin contact pin, by the corner contact pin, can expand to vertical plane.Need to prove, when extendible omnipotent LED template was expanded, on it, socket not only played the effect of being connected and fixed, and also plays simultaneously intermodule electrical connection effect, can carry electric current.Therefore, this extendible omnipotent LED template can be spliced into various figures or word by expanding, and does not need to connect in addition power lead, and is very easy to use quick, can make easily signboard or the advertising lamp of various styles.

As further illustrating of such scheme, described socket is the single socket with 4 round jacks, and two of the centres of single socket pin is electrically connected by PCB, and two other pin also is electrically connected by PCB.Middle two pins and two other pin are received respectively the both positive and negative polarity of power supply, no matter just connecing or reversal connection between the extendible omnipotent LED template of polylith, the error-polarity connection of power supply in the time of all can avoiding socket to connect can not occur causing on the contrary short circuit phenomenon because of polarity connection.

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

Application as such scheme, a kind of three-dimensional LED advertising lamp, it is characterized in that: it becomes cube structure by at least 6 above-mentioned extendible omnipotent LED template splicings, be provided with the pin contact pin or the corner contact pin that connect its socket between extendible omnipotent LED template adjacent one another are, be inserted with some the LED devices that form pattern or word on extendible omnipotent LED template.

The quantity of the quantity of extendible omnipotent LED template depends primarily on the electric current that in the load-bearing limit of plug and PCB, the printing copper sheet can pass through.The quantity of extendible omnipotent LED template is larger, and it is long-pending also just larger that it splices the LED lamp body, and its brightness is also larger.Preferably, the quantity of described extendible omnipotent LED template is 6 or 24.

In addition, above-mentioned extendible omnipotent LED template also can be assembled into word or other pattern.

From the above mentioned as can be known, the utility model has the advantages that: simple in structure, easily make; Expansion is good, connection is quick, assembling is flexible, easy to maintenance, facilitate field fabrication, the user only needs that versicolor LED is patched extendible omnipotent LED template can make LED signboard or advertising lamp, thereby has reduced the cost of manufacture of LED signboard or advertising lamp.Splice flexibly performance because extendible omnipotent LED template has, therefore, can be used for the fields such as initiative advertisement signboard.
