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 how yo konw 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 bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!: The most direct and simplest answer is the power problem.

Q: How to choose the bulb power?: If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.

Q: What are the characteristics of LED bulb?: The service life is long, and the average life can reach 100 thousand hours.

Q: Will the power of the LED bulb grow longer and longer? Why?: The LED bulb does not become more powerful for extended periods of time.

Q: LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

Q: Choose which light bulb LED bulb is the healthiest: Choose LED lights, first, no strobe, strobe damage to the eyes, second color index to be high, true and clear. For the quality, choose to heat better, high power factor, so that the relative power of the lamp, power saving, durable

Q: Is there any flicker in the LED bulb?: First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!

Q: Want to find common features, unified purchase accessories repair!: The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
