Whenever the Christmas and New Year these grand festive come, the various buildings and trees and flowers are beautiful s with gorgeous dress against the backdrop of the LED strip lights, apparently, LED strip lights have been used as excellent decorative lamps into our lives, but, for most of us, it is not clear how to install LED strip lights, here I will guide you how to install the LED strip lights.

Scope

LED strip, LED light bar has been widely used in furniture, automotive, advertising, lighting, ships and other industries.

Installation Method

` the bandwidth of four wire LED strip lights is about 22mm, the thickness is about 8mm, the weight is about 0.25kg / m (4 meter by Kg)

athere are a total of four wire conductors for the LED strip lights, three rows of lights (note not the four rows of lights), there is 1 meter and 24 lights in each row, 24 * 3 = 72. Because the power of each lamp beads is 0.05W, the power of the 72 beads LED strip light is: 72 * 0.05 = 3.6W.

bthere is the “scissors” mark per meter , only to have to cut on the tag, the scissors cut or the wrong side will lead to that one meter does not shine! Some miss a few because of hitting the mark, it is best to look the mark position carefully before you cut, according to the middle of no where connections to be cut, which can be carefully seen.

c Each strip light must be fitted with a special plug (a plug with a transformer); connection sure to remove the clear plastic cover, and don’t cover until the light is connected and tested. Must not be directly connected with the cover, the short circuit is easy to occur!

When the strip lights is installed, it is generally put on the light trough, and put straightly is OK, you can also use string or thin wire to fix. For the exterior or vertical loading, a clip and a tail plug need to be purchased . The genuine clip is fully transparent, preferably mark with the waterproof glass glue after the installation in the tail plug and the plug, so better waterproof.

LED lighting requirements for low-voltage driver chip

1.The input voltage range of the nominal DC of the driver chip should satisfy 8 ~ 40V, which is to cover a wider application needs. Pressure capacity is preferably greater than 45V. When the input is AC 12V or 24V, the output voltage of the simple bridge rectifier will fluctuate with the grid voltage, especially when the voltage is high, the output DC voltage will be high. If there is not wide input voltage range for the driver IC, which tends to be

breakdown when the grid voltage rises, thereby burning the LED light source.

2.the nominal output current of the driver chips required is greater than 1.2 ~ 1.5A. For the LED light source used for lighting, the nominal operating current of 1W LED light source is 350mA, 3W LED light source nominal operating current is 700mA. Power LED light source needs more current, the LED lighting driver IC selected must have enough current output, the driving IC must also be operated at the optimum working area that is 70 to 90% of the full load output when the product is designed. There is poor heat dissipation when the driver IC is used in the small spaces at the full-load output current, which easily lead to fatigue and early failure.

3.the output current of the driver chip must be kept constant, so to stabilize the LED light, no flash. When the Same batch driver chip is used under the same conditions, the output current should be as consistent as possible, which is discrete to be small, so that ensure the effectiveness and orderliness on the high-volume automated production line. For the drive chip whose output current has certain discrete, required the sub-file selection before the factory or production line, adjust the size of the resistor set by the current on the PCB, so that LED constant current driver of LED lamps board produced is consistent with the emission luminance of the similar light source in order to maintain the consistency of the final product.

4. the package of the driver chip should facilitate rapid cooling of the die of the driver chip, such as the die is directly bind on the copper, and there is a direct extension of the pin outside of the package, in order to that the copper foil directly soldered on the PCB rapidly transfer the heat. If the chip that is similar to the 4X4mm through 300 ~ 1,000 mA current for long time, the power consumption and heat is inevitably generated, therefore, the physical and thermal structure of the chip itself is also very important.

5. driver chip anti-EMI, noise and high pressure capability is also related to that whether the entire LED lighting products can pass CE, UL certification, so the advanced topology structure and high-pressure production process should be used when the driver chip is designed.

6.driver chip’s own power requirements is less than 0.5W, the switching frequency is greater than 120Hz, in order to avoid visible flicker produced by the frequency interference.

In short, LED driver chip urge the green lighting to the development of innovative design. LED lighting without driver chip, requiring multi-functional LED light source driver IC. If the power supply that is less than 36V AC is used for the LED lamps, the non-isolated power supply can be considered; if the choice is 220V and 100V AC power, you should consider the isolating power supply. For the AC 100 ~ 220V drive chip directly used, because the application excessively depends on the volume demanding, there is higher demand, the greater difficulty on the technically, the countries are currently making efforts to develop. The Massive demand for LED lighting market gives the chances of success to all the IC design company again, if rapid transformation and pushing the product as early as possible, then there is a lot chances to win.

As people’s living standards improve,more and more families choose energy saving LED lamps, LED crystal lamps, LED flood light, LED energy-saving lamps and other LED lighting fixtures, but with the increased use of time we will inevitably encounter that the LED light is damaged, so today I share with you how to repair the damaged LED lamps, this experience is suitable for all LED lamps.

Tools / materials

Multimeter

Methods / steps

1.First, we must ensure that there is no problem with the circuit of the LED lamp in our own families, the main problem is that the switch has gone wrong , the switch is the focus of our detection.

2.Check the the power converter on the back of LED lights (that white box that is in the figure is the power converter), for this,the converter would be directly removed, and powered with a multimeter to measure the voltage or current, if the power converter is damaged,which can be directly purchased for the replacement, it is generally very cheap.

3.If there is no problem with the LED power converter,then we can cut the multimeter to the voltage output gear, and then place in the corresponding positive and negative point of the LED lamp to look up it will be lit or not. Replace it If it is can’t be lightened up.

4.Generally speaking, after the above three steps,60% of the LED lights problem can be solved, so our LED lights should be able to re-radiate the glory.

Precautions

Because LED lights are high-tech products and require a 220V power,we must pay attention to protection against electric shock during maintenance, and if you have doubts on the maintenance ,please check the reference material the qualify manufacturer and supplies offer.
