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 band of light a metre?: At present, our company produces LED soft lamp with 30 yuan /M hard lamp, with 70 yuan /M

Q: Can the LED light band be used alone in the open air? Is it waterproof when it rains?: Are you talking about the LED belt? Light belts are generally not recommended for outdoor use because the performance is relatively less stable. You can use outdoor lights such as cord lights or guardrail tubes.

Q: Does the LED lamp come in a waterproof type?: LED waterproof lamp [2] with very soft PCB board as substrate, RGB chip Chip as the luminous body, light emitting angle of 120 degrees, each 50cm has 15 LED, 24 LED, 30 LED three specifications, arrangement of luminous body uniform in type PCB plate, color soft, light mixing evenly connected with each other the use of plug-in exquisite joints, appearance is very slim and compact, with 3M adhesive, horizontal soft light is a multi-purpose.

Q: Does the LED belt need 3C certification?: LED lights belt does not need to do 3C certification, if you want to do domestic certification, you can do CQC certification, if you have drive sales, then the purchase has 3C certified LED driver on it

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: How to solve the problem of LED lamp heating problem?: Specifically, the heat generated by the LED chip comes out of its metal heat sink, first through the solder to the aluminum substrate PCB, and then through the heat conductive glue to the aluminum radiator. Therefore, the LED hotel engineering lamp heat dissipation actually includes the heat conduction and the heat dissipation two parts. However, the size of LED lamp cooling according to power and place, also have different choices.

Q: Can different color LED lights come together?: Hello, LED lights with different colors, but the same voltage can be connected together, monochrome as long as it is connected to the positive and negative, you can light.

Q: LED how much watts does the lamp belt have?: Look, there are a few light-emitting diodes, the general light-emitting diode from 1W to 3W is the majority, home restaurant lights with a few such small lights, 7W, a lamp, the interior is two light-emitting tubes.Of course, LED lights also have high power, but most of them are energy saving, power saving, and much less power than other lamps of the same brightness.The light emitting diodes with the power than lighting small, mostly in 0.1W, you can know about the number of count diode power, but it is best to calculate the current through the voltage, P = UI, so that more accurate.

Q: LED lamp with a whole such as bad if not how to detect the lamp with a lamp quality: Very simple, 2 battery 3V, each lamp does not light the ends of test, bad, LED is also a diode, try again when the reverse voltage is equal to the open circuit test for other beads, beads are measured

Q: My living room, I do not want the ceiling can use LED lights? How can we install it?: First, punch the holes on the top, fix the panel, or screw it.
