LED lighting industry found "new world" - new connection technology (Photos)

In the process of rapid development of solid-state lighting, designers often put the main focus on LED, heat, and optical drive and so on, and the connecting parts for only a very small proportion in the system cost, easily neglected or even ignored. And now, after several years of practice, designers have gradually found that these seemingly insignificant components often relates to the entire LED lighting system will eventually meet the corresponding reliability, waterproof grade, long life design requirements. Connector has become one of the key components of solid state lighting system, which directly affects the quality of the product and the overall impression of the client on the design quality. To some extent, can be described as "details determine success or failure, it is related to China solid-state lighting (Solid State Lighting, or SSL) industry can go further, to achieve greater development in the commercial road. Tyco Electronics (Tyco Electronics) with more than 60 years of experience in the design, to connect the field of innovation, pay close attention to the development of SSL industry, the effort to build a connection can fully adapt to various solutions for LED lighting applications. These innovative innovative products designed for solid-state lighting, covering almost all of the major applications of solid-state lighting.

Wire to board / hand on board welding history

A few years ago, in order to reduce the cost of manual welding, wire plate, plate to plate has been a lot of China LED lamp manufacturers helpless choice, and now to solve the problem of radiation of LED lighting, aluminum substrate with good heat conduction performance has been widely used, such as to continue to adhere to the manual welding, the connection quality risk will be greatly improved. As everyone knows, the welding process requires an optimum welding temperature, manual welding when the pad iron head on the aluminum substrate after the solder temperature due to good thermal conductivity of aluminum substrate does not rise rapidly, extremely easy to cause the solder false and welding quality problems, seriously affect the quality of products. To solve these problems, Tyco Electronics developed a series of high-speed surface mount (SMT) solid-state lighting line on board, board to board connector, the shell is made of high temperature plastic, with LED lighting module manufacturing reflow process commonly used, connectors and LED go into surface mount. SMT and the hole plug connector (Figure 1), whether ordinary or plastic resin plate, aluminum plate, can provide fast and reliable cable termination, this small size low height SMT and a two connector, very suitable for the application of LED lamp, lighting controller and other interconnection using plug-in wiring. The connector conforms to the RoHS specification, terminals with copper alloy, nickel layer as the bottom plating, tin surface, the shell is made of high temperature plastic, flame retardant grade reaches UL94-V0. Although the plug-in LED connector is most suitable for 18AWG 6~16 core twisted wire, can also be used for the 18~22AWG of the solid wire and 18~20AWG pre bonding multi strand wire.

With the LED lighting applications continued rapid development of lamp manufacturers committed to the development of the installation and maintenance of lighting system at a lower cost solution (Figure 2). To this end, Tyco Electronics launched a new non polarity plug socket integrated board to board connector and the corresponding line to board connector, to provide customers with a complete set of connectivity solutions.

The plug connector can be used to support the 18 ~ 22AWG (0.3 ~ 0.9 mm) strands of wire diameter, material using crimping type copper terminals and UL94-V0 with flame retardant grade thermoplastic shell, with plate connectors used and can provide active locking function, to ensure the safety of the connection.

The small polar plate insert socket integrated design to board connector, compared to the traditional design with polarity, can provide more installation LED flexible printed circuit board between the connector can be combined with two pieces of circuit board to complete the connection through the horizontal or vertical sliding. The design of the vertical sliding connection makes it more convenient to replace the circuit board in the middle of the LED lamp string, and only needs to lift the circuit board to be replaced and then put in the new circuit board.

The plate end connector can be used not only for plate to plate, but also for wire to plate connection. The advantage of the non-polar design is that the user only needs to store a product of the board end application, which reduces the complexity of the inventory. Because the design of the plate end is designed into the same structure, the design is simplified. The packaging of the terminal winding mode is convenient for the operation of the high-speed terminal equipment.

Outdoor lighting "safe" and "waterproof" is the key

In the end of the LED LED drive power source module between the outdoor connector is often on line or on the line board, in addition to convenient installation and disassembly, reliable safety and shall have a safety certification also has become the development trend of the industry. In the process of application, the outdoor connector also has a high demand for waterproof and moisture proof. Tyco Electronics IP67 small SlimSeal SSL connector is a can deal with all kinds of harsh lighting application environment of small sealed single row LED connector, meet the needs of small flat, convenient plug needs. Products to achieve the IP67 seal grade, suitable for residential, commercial buildings and other construction applications, such as indoor and outdoor environment, especially suitable for billboards, outdoor exhibitions, street and tunnel lighting, such as exposure
