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: What is the power consumption of the LED lamp belt?: If you use LED lights with more, then in accordance with this parameter directly multiplied by the number of meters, you can get the use of LED lights with the daily, monthly, annual power consumption. In fact, in the family, the daily utilization rate is not 8 hours, even if calculated according to 8 hours, the power consumption is almost negligible. Therefore, we can rest assured that the use of, do not install when installed, but did not dare to use the back, it is a waste of resources!

Q: LED lights with lights, some light, and some light, or in the middle of a section will not light: Whether to buy is cheap chips, is lit when the naked eye can see the chip in the core... (good chip luminous flux is relatively high, there is a chip dazzling, bright look not clear) of each section on the chip is a multiple of 3 or 3? If so, that's the shoddy chip. It's broken.

Q: LED lamp with frequency converter burn, what's the matter?: In the inverter power supply, the inverter input special filter, or inverter input dedicated reactor to try.

Q: What's the light belt? What's the use of the LED light?: The light belt is the abbreviation of the LED light belt. Most people are not accustomed to the noun when they say it is too long, so the LED in front is omitted. It is called the light belt directly. In this way, the band with the name also includes a lot of big, second line, big three lines, round, second line and so on, the direct use of wire to connect LED, instead of FPC or PCB old band, of course, also includes flexible light band and hard light belt.

Q: How to distinguish the LED lamp belt is the high voltage lamp belt or the low voltage lamp belt?: Here only introduces the patch belt! The biggest difference is: the high voltage lamp belt is in a meter parallel to the core line (you can 100 a pass!) The low voltage is directly to the line power supply (due to the thin line), if the line is long, it is bound to cause the back part and the first half of the brightness is completely different!

Q: How can the LED flat band be fixed on the outer wall corner?: How to install the LED corner lamp, there has been a guest asked us, in fact, this is a very simple thing, but because we are professional will think so, and our customers, but not necessarily think so, there are still many do not understand, because of fears that the equipment is not up, so in with us really beautiful Taobao lighting factory outlets, customer service communication, many guests said, temporarily buy a sample back, see fit.

Q: LED does the light carry electricity?: 20W energy-saving lamps are not more than 20W, if LED does not light, electricity, and that is because the purchase of cheap. 3528, a lot of brightness levels, 3-4lm, 4-5lm, 5-6,6-7, now has 7-8lm, a 3528 power of about 0.06w, according to 7-8lm is also 116-133lm/w, if 3-4 or lower it is only 50-60lm/w, the price is not the same, certainly not a kind of efficiency. Lights with the market already do mess, basically are used in garbage beads.

Q: LED can the band be cut casually?: If it is a low voltage lamp with the lamp, is generally three cut, similarly, must also be in place to cut cut mark. It is recommended to choose photon lighting, LED low-voltage light belt, personalized custom, arbitrary!

Q: Is the LED belt with a constant voltage transformer or a constant current transformer?: LED lights with all kinds of varieties, with high and medium pressure, low voltage, AC and DC, lamp with internal general only by the current limiting resistor to protect the LED chip, is not reliable, of course, preferably with constant current drive lights, but seldom have this right drive, generally uses the switching power supply has regulated performance they are very sensitive to the change of the LED drive, the power supply voltage, the voltage variation of the weak will bring great changes in current, exceed the rated current of LED is very easy to damage. So the requirements of power supply better performance (in order to avoid the current instability), a better solution is to lower the power supply output voltage, the LED voltage derating, even if the impact is not accidental, overcurrent, caused damage to the LED, such as the low voltage of 12V can be adjusted to use low 11.5V. This will extend the service life.

Q: 5730led hard lamp, with one meter long and 72 beads, what is the power?: In fact, hard light with more use of low voltage, 12V or 24V, the use of resistance to limit the current, then add the actual resistance loss, more than 40W, but with such a high light power is not enough, because the heat problem, up to 20W, safety should be controlled in 10-15W.
