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: Led how much is the price of the lamp?: LED lamp belt price is according to its quality to evaluate, poor quality a few dollars a meter, good quality of more than ten dollars a meter, recommend the use of photon lighting technology, LED lamp belt, there is always a LED light belt for you.

Q: What is the wattage of the LED lamp with one meter?: Four line lamp belt, there are four wires, three rows of lights, each row of 1 meters, 24 lights, 24*3=72. For each lamp power is 0.05W, power 72 pearl light belt: 72*0.05=3.6W.

Q: One meter band of LED lights. Let me cut it in the middle. Then I found a thread and put it together. Why didn't it turn on?.: Then the outside two main lines also need welding.Be sure to wrap it with insulating tape. Don't short-circuit it with the outside. The outside is 220V high voltage.

Q: LED how much watts does the lamp belt have?: This depends on the specific amount, I in monochrome lamp 5050 bar for example one meter 30 lamp is 7.2W meters 60 light is 14.4W

Q: What's the difference between a LED light strip and a light strip?: With lights, others will be included in the LED soft light in this category, but also includes some flat three lines, flat four line, used for plug-in lamp lamp series, after welding, injection molding process, body is bigger than LED soft light, used for outdoor lighting, the waterproof performance is good, but can not reach the brightness the brightness of LED soft light on the lamp.

Q: How do you calculate the current of the LED light belt?: Non lighting each group current is about 10~20mA., each 3 lamps are a group. Lighting type about 50mA a group (different manufacturers, the current is also different), then you see how many lights, divided by 3 to get the number of groups, the number of groups of single current can get the total current

Q: How do you control the two LED lights with a remote control?: A controller using light and white light RGB can not only remote controller is used to control the RGB is also the color of colorful light, white light is remote control of current and voltage to control the light, and the light is 4 RGB with the line, white is the 2 with the two, not mixed together with a controller!!

Q: Which of the 12 volt LED light band and 220 volt LED lamp is brighter? What's the difference in electricity costs? Want to use it in the mall counter, 12 volts: 12V is commonly known as low voltage line, and 220V is high voltage line.A few years ago, high voltage line technology is not mature, low voltage line can be broken, a chip at worst, in series near the other 2 (3 string). And then the high voltage line is bad, one will be bad on the whole meter.Later, the high voltage line technology mature, and now also three chips in series, pay attention to the procurement, ask the relevant personnel, do not buy the oldest high-voltage wire products on it. When I was 12, the hotel project was still using 12V, and now I've switched to 220V altogetherBrightness of the big difference, cheap 5-6 meters per meter (I have seen the cheapest, 2 meters a meter, no warranty), relatively bright manufacturers, ex factory price is 13. 5050 patch specifications, if you use high brightness chip wafer. (it's hard to find on the market.)

Q: Where is the difference between the LED lamp belt and the ordinary lamp?: The light emitting principle of LED soft light band is different from that of incandescent lamp and gas discharge lamp,The energy conversion efficiency of LED soft light band is very high, and the energy consumption of incandescent lamp can reach 10% in theory,LED soft light band, compared to fluorescent lamp can also achieve 50% energy saving effect. Energy saving effect is remarkable, which is of great significance to China, which is very energy intensive. The utility model does not contain toxic and harmful substances (such as mercury), avoids the two pollution of the fluorescent tube rupture and overflows mercury, and simultaneously does not interfere with radiation.Besides the optical properties of light, compared with incandescent and fluorescent lamps, 1 LED light less, using a plurality of LED.LED itself so require radiation range with a light emitting area is small, light, with advantages of light in a hemisphere distribution of rotational symmetry, plus lenses and mirrors, can constitute a a good source.

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.
