In the market, while we see led lamp line, no matter from the appearance, or utility, looks the same, but the price is high, medium and low, so the hidden secret? It's all about the circuit board, and then we'll uncover the secrets of the circuit board in the led line lamp.

When making led line lamps, the essential raw materials are our circuit board, light source, electronic components, shell, glue, waterproof wiring and other materials. If you think PCB board and aluminum substrate are only two kinds of materials, that is wrong.

It is only the circuit board that can find so many problems. Do you still use the "it" of "flat, beautiful and positive" to do the lighting project? Don't exist fluky psychology, engineering, not small, tear open outfit is very expensive, maybe in six months there is no problem, but does not guarantee the quality assurance you need 2-3 years of this period of time can be used normally, how much of a risk without spending much money.

In view of the material to analyze the PCB board, PCB also has many kinds of quality level, on the market the most cheap line lamp selection is the secondary material of PCB board, the board after heated easy delamination, copper foil is too thin, poor adhesiveness copper foil layer and PCB layer is easy to separate, not to mention how line stability, plate are also count on line is stable? No kidding! Everyone's busy! Most inexpensive line lights do not have a reasonable line layout and test to measure its reliability and stability. And the production of the normal led line lamp manufacturers will be able to do this to sell in the market.

1, look at the label on the lamps and lanterns, general normal line lamp manufacturer can label before delivery of lamps and lanterns indicated the specific parameters of the product, we can through the tag to see the line lamp voltage is used by many volts.

2. How to do without labels? On lamps and lanterns is no label mark voltage is how much, if the lamps and lanterns is transparent glue, can clearly see the inside of the lamp body components, through its lamp bead amount, in the judgement of components such as resistors, capacitors, and then from low to high voltage test the lamps and lanterns of lighting conditions, can choose some testing tools during the test. If you can't see the internal components of the lamp, you need to disassemble the lamp for testing.

3, led lamp line generally chooses lamp bead, single voltage at around 1.8 3 v, general electric current can control in the 18th ma - 20 ma, for different number of mild color chip, each a different voltage led lamps and lanterns, eventually needed by the designed to engineer or technician to check.
