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 placed on the PCB circuit board that connects in the plastic casing and fixes; Then with in the epoxy resin injected plastic shell; Wait for behind the epoxide-resin glue water cure the PCB circuit package in plastic casing, 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; And after going into, glue to vacuumize the removal bubble; Wait for that the needed time of process of solidifying is longer; Encapsulation usefulness epoxide-resin glue exist problem that can variable color of long duration, encapsulation is accomplished the back as if detecting defect ware, is difficult to remedy.

The utility model content

The utility model promptly is to the above-mentioned weak point that in LED module water-proofing treatment process, exists at present, and a kind of design of adopting power line and shell integrated injection forming and single installing hole is provided, and the module that uses the method to make can solve:

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

(2) existing module has a plurality of installing holes, installs inconvenient;

(3) 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 integral type water proof type of the utility model LED module comprises shell, power line, PCB circuit board and is welded on the LED on the PCB circuit board, it is characterized in that:

1, in the described LED module, the shell top is uncovered, is provided with several terrace with edges in the shell bottom surface;

2, power line pass two sides of shell and terrace with edge the bottom and with the shell integrated injection molding, power line comprises cathode power supply line and anode power cord, has the fixing hole that is positioned on anodal and the anode power cord on the terrace with edge;

3, the PCB circuit board places on the terrace with edge of shell, and have with terrace with edge on the corresponding screw in fixing hole position, bolt passes screw, fixing hole and locks respectively in the core of into cathode power supply line and anode power cord.

Further, also be provided with erecting bed on the bottom surface of the shell of said LED module, on erecting bed, have installing hole.

In order to obtain better waterproof effect, in described shell, be perfused with fluid sealant.

The material of said shell comprises plastic cement.

The described LED module of the utility model, power line and plastic shell adopt the moulding of integrated through injection molding formula.

Injection moulding is a kind of method of industrial products production moulding, and product uses rubber injection mold and plastic injection-moulded usually, and injection mo(u)lding realizes through injection machine and mould.The rubber injection mold moulding is a kind of production method that sizing material is directly vulcanized from the machine barrel injection model, and molding cycle is short, production efficiency is high, product quality is excellent; 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.

The described integral type water proof type of the utility model LED module has following advantage:

1. power line and shell integrated injection forming; Bolt is locked respectively on shell in the core of positive pole/anode power cord through the screw of pcb board; Fixing pcb board; Play the effect of PCB circuit board and power line conducting simultaneously, removed trimming, peeling, welding three process from, simplified production procedure effectively;

2. described LED module adopts compact structure to combine the casting glue sealing, and water proof and dust proof is effective;

3. adopt single installing hole, reduced volume, easy for installation, be more suitable for being applied in above the advertisement sign in little space.
