5.FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Q: Why does the length of the LED band fade with length?: When the supply current increases, the internal resistance remains unchanged, resulting in a decrease in the output voltage. The LED and resistance of the light belt are fixed. So the current will be small

Q: Home decoration, want to buy lights, with what kind of lamp well?: Living room: the living room is treat working places, but also the family spends most of the time, to create a warm atmosphere of warmth, so the solemn, bright chandelier or ceiling lamps.

Q: LED lights with a meter, about how much W?: Each manufacturer because the chip is not the same, will cause the LED lamp working voltage and current is not the same. Therefore, the same band of rice LED lights on the market, their power will vary.

Q: How about the power of the LED lamp?: LED has different chips that cause different currents. For example, there are 0.011A, 0.015A, 0.028A, and so on. It should be said that different batches of LED chips will have different values of current, so each batch should be measured by an instrument

Q: How to install the car LED lamp belt?: Each LED lamp belt must be equipped with a special plug (plug with transformer); when connected, it is necessary to remove the bright plastic cover, then connect the test lamp and then cover it. Cannot cut directly with the lid join, such short circuit is easy!

Q: LED lights with 0-10V dimming when flashing what reason?: When the input voltage is lowered, the loop current is also reduced to below the SCR holding current, and then the thyristor is turned off.

Q: LED can the light belt be put in the water?: Good waterproof treatment, can be placed in the water, and put in the water lamp belt, usually use sleeve filling glue, can achieve the effect of IP68.

Q: LED how is the band embedded in the steps?: LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good.

Q: LED lights bring what is high pressure, what is low voltage?: Low voltage LED light belt is 220 volt cross flow, 12 volt DC power supply (with a small converter box), can also be battery or battery power supply, generally with a length of 6---10 meters long, suitable for civilian use. The high voltage LED light belt is 220 volt AC direct power supply, usually 50---100 meters long, suitable for commercial use.

Q: According to the LED lights, how to judge the quality of the products?: Look at solder joints. Regular LED lamp manufacturers with LED band produced by SMT patch process, with solder paste and reflow process produced. Therefore, the solder joint on the LED light band is smoother and the solder flux is not much, and the solder joint is in an arc shape extending from the FPC pad to the LED electrode. However, the solder joints of the LED lights in the Shanzhai version are not uniform, and most of them appear as a dot to weld the feet. At the same time, there are different degrees of tin tip, which is a typical phenomenon of manual welding.
