Background technology

The LED module is exactly together regularly arranged by necessarily LED, and encapsulation is got up again, adds the product that some water-proofing treatment are formed.Be mainly used in the effect at night of showing advertisement font (acryl, plastic uptake) and sign; It is with literal or be designated media, is installed in building top or metope, can show sign effect on daytime; Can utilize LED as illuminating source again; Show other a kind of effect at night, be equipped with LED illumination application control system again, literal or sign are carried out dynamic video control.

In the LED application industry, the LED module is widely used in places such as advertising lamp box, sign signboard, propaganda Warning Mark because of characteristics such as its super brightness, low-power consumption, long service life, simple installations.Along with the maturation gradually of LED module technology, its range of application also can be more extensive.

But the present LED module overwhelming majority on the market is to adopt multiple conducting wires to be welded on to play power supply I/O effect on the circuit board, and this kind method production efficiency is low, and causes bad phenomenon such as both positive and negative polarity connects instead in the process of a plurality of module cascades, rosin joint easily; The most waterproof effects of LED module are bad on the market, are not suitable for using under the environment big at fog, that rainwater is many.

The LED module is being carried out the method that water-proofing treatment method commonly used has the employing casting glue to seal at present; This method is injected shell with epoxy resin; Wait for behind the epoxide-resin glue water cure that with the PCB circuit package to reach the purpose of waterproof, the defective of this method mainly is that the volume of product is big, operation is loaded down with trivial details, needs the configuration epoxide-resin glue in plastics; And to vacuumize the removal bubble after glue is gone into, wait for that the needed time of process of solidifying is longer; Another one method for waterproofing commonly used is that though ease of assembly, cost is higher with power line and shell integrated injection forming, and after in injection moulding process, bad product occurring, is inconvenient to dismantle quadric injection mould.

The utility model content

The utility model promptly is the above-mentioned shortcoming to prior art, provides a kind of employing power line (four-core winding displacement) and shell integral type beer molded design with single installing hole, uses the module of the method making can solve following problem:

1. the production efficiency that the mode of existing module power line welding causes is low, and polarity connects anti-problem easily;

2. existing module classification of waterproof is low, can't be big at fog, long-term work under the environment that rainwater is many.

Specifically, the described a kind of water proof type LED module of the utility model comprises shell, four-core winding displacement, PCB circuit board, is welded on the several LEDs on the PCB circuit board; It is characterized in that: in the described LED module; The shell top is uncovered, and the bottom surface is provided with terrace with edge, the four-core winding displacement pass shell side and terrace with edge the bottom and with the shell once injection moulding; Top corresponding to each bar line of four-core winding displacement on the terrace with edge has screw; The PCB circuit board is placed on the terrace with edge, and the screw that bolt passes on PCB circuit board and the terrace with edge is fixing in the enclosure with the PCB circuit board, and the core of bolt and four-core winding displacement is in contact with one another.

Further, the enclosure of described LED module is filled with casting glue and seals, to obtain better water proof and dust proof effect.

For the ease of described LED module is installed, be respectively equipped with installing hole in the both sides of shell.

In the said LED module, the material of shell comprises plastic cement.

The described LED module of the utility model, four-core winding displacement and plastic shell adopt the moulding of integrated through injection molding formula.

Injection moulding is a kind of method of industrial products production moulding, realizes through injection machine and mould.Plastic injection-moulded is a kind of method of plastic products, utilizes pressure to annotate in the plastic products mould in the plastics of fusion, and cooling forming obtains wanting various working of plastics, and the most often the plastics of use are polystyrene at present.
