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: Can the 220V LED belt be transferred to the 12V on board?: If you have a little electrical knowledge, the 220V lamp is divided into 20 sections, the 20 section light into parallel form, and remove the LED light input part of the rectifier part (circuit AC to DC), directly to the 12V DC voltage on it. In fact, LED 220V lights, is the 220V AC into 300V (the voltage is not certain, some have a buck, there is a full wave rectifier could reach 380V DC DC), added to the N series of LED lights, as long as you have this clear voltage on the line; because the working voltage of LED lamp the DC and DC voltage of single LED light value is generally between 2.7V~4V.

Q: LED can the band be cut at will?: Each of the 3 LED lamp 12VLED lamp with a module, a 220V lamp with general meters, marked.

Q: How many watts are there in one meter, 70 bead, LED lamp?: A 70 meters Pearl LED lamp belt, if using 5050 beads, its power is 14 watts; if the 3528 beads, its power is 4.2 watts; if the 2835 beads, its power is 14 watts; the lamp power is not the same.

Q: LED the band is cut off in the middle. Is it still bright ahead?: LED flexible light band, after a lot of checks and checks, there will still be not bright phenomenon. The reasons are as follows:Packaging protection 1, LED lamp is not perfect, resulting in beads impacted and damaged during transportation.2, LED flexible light strip welding weld phenomenon in the process of transportation and vibration caused by soldering off caused light is not bright.3, LED flexible lamp with less solder, solder joints easily fall off4, LED flexible light band soldering quality is not good, LED flexible light band in the bending process, solder joints prone to cracking, peeling phenomenon5, LED flexible light belt installation when the bending angle is too large, resulting in LED flexible light strip solder joints and copper foil separation and lead to light

Q: How much is the output voltage of the LED lamp belt driver?: A series parallel circuit and the main LED bulb lamp with you, if you are a series circuit with 3 LEDs, the driving voltage is 12VDC, 6 beads, the driving voltage is 24V, of course, the circuit should be added to the current limiting resistor.

Q: What are the requirements for the LED light driver?: The circuit with a voltage stabilizing device has an upper limit for the input voltage, and once the voltage rises, the power supply equipment may cause serious irreversible physical damage. So overvoltage protection is very important.The LED lamp power supply is a device that provides power to the LED lamp, also known as the LED power supply, which provides the electrical energy needed by all the components in the LED luminaire. The size of power supply, the stability of current and voltage, will directly affect the performance and service life of LED lamps.

Q: What are the specifications of the LED lamp band and which ones are more commonly used?: With the progress of the times, the improvement of living standards, people's understanding of the family has become different, but advocating "nature" is the desire and pursuit of the family. Led to people's demand for home decoration more and more high, LED lights with everyone become no stranger, led band with more and more widely used, and gradually become a trend of the trend. LED light band is both beautiful and practical, today we will come to understand the knowledge about LED lights, what is led band?

Q: Led how to install the light belt?: Each interface must be solid and free of potential defects. When outdoor installation, the interface must be sealed with glass glue or other appropriate methods to ensure that the interface is flooded.

Q: Can anyone tell me what's the difference between LED lights and indoor and outdoor installations?: Zhongshan bright lighting LED lamp production as an example, behind each LED lamp belt are affixed with self-adhesive 3M double-sided adhesive, the installation can be directly off the surface of the 3M double-sided adhesive stickers, and then the lamp strip is fixed on the installation place, hand press flat is good. As for some places need to turn or grow, what should I do? Very simple, LED light belt is a series of 3 LED as a series of parallel circuit structure, each 3 LED that can be cut alone.

Q: Can you tell me if the LED light belt can be lit for a long time?: The reason why the LED is durable is that it does not cause filament fusing. LED does not stop working directly, but it degrades as time goes by. It has been predicted that high quality LED can maintain more than 60% of the initial brightness after 50000 hours of continuous operation. Assuming that the LED has reached its rated service life, it may actually still shine, but the light is very weak. In order to extend the life of LED, it is necessary to reduce or completely dissipate the heat generated by the LED chip. Heat is the main reason for the LED to stop working, and the life of LED is related to LED chips and ELDerly drivers.
