FAQ

 

1-May I have your samples for existing items?
According to our sample policy, samples are free of charge for our common existing ones within a certain amount but customers need to bear the express charge. If customers have an international express collect account no. for FedEx, UPS, DHL and so on, this will be more convenient for us.For long-term business, we could bear the express charge.If customers are satisfied with the finished samples and will settle the first order, we will start to refund the sampling charge. For actual refundable procedure, this will be finalized according to actual sampling charge, the first order amount and actual communications.

2-Could you do sampling according to my actual sample, special demand, design or own idea?

Our R & D dept. has experienced engineers in structure and electrocircuit. And we have good cooperative factories in molds for plastic and metal. Based on these, we are able to achieve your demanded samples.

 

3-How do you control the quality?
We have strict quality control system including incoming material inspection, production line management, final full inspection and random inspection on loading. Based on these, we are able to deliver final high quality products for you.

 

4-What's the period of validity for complaint?
Normally, we accept the complaint within one month after receipt of the goods. For some special circumstances, please kindly contact with our sales for your actual order.

Q:What is the rated current for the white patch LED?
Generally small power LED rated current is basically 20mA
Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
Table 1, contact electrostatic protection LED product should be covered with protective electric tape, and its reliable grounding; 2, personnel shall wear groundstrap in contact with LED (best for cable, protective gloves, anti-static ring) allows better wear anti-static clothing, anti-static shoes and static electricity cap; 3, the application in the process of exposure to LED equipment must be reliable grounding, such as iron, shearing machine, bending machine and welding equipment. Conditional still can install plasma fan to eliminate electrostatic; 4, in use or when designing electronic circuit, must consider the harm that excessive current has to LED
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
Q:Why is the patch LED blue light dim?
When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.
Q:SMD LED specification
The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.
Q:How does the LED patch lamp differentiate between positive and negative poles?
You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
Q:Notes on patch LED
Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
Q:Patch LED light broken one, short circuit can use it?
Patch LED lamp LED wick is usually series, and a bad, can temporarily short-circuit, temporary use, because after short-circuit, this LED wick voltage will be assessed to other LED wick, accelerate other LED wick aging.The damaged LED wick needs to be secured as soon as possible.
Q:Welding method and notice of SMT LED
I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.
