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 how to success.

Q: LED thread specifications for bulb bulbs?: Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q: Ordinary lamp LED bulb can?: Absolutely, without any effect. It can be directly across to look at the opening of several inches.

Q: What are the types of LED bulb?: According to the radiator shell to points, can be divided into plastic shell, aluminum radiator and ceramic shell, in general, the ceramic shell heat radiator is best, but the price is relatively expensive, the widespread use of aluminum shell, moderate price, good heat dissipation performance

Q: What does the LED bulb patch mean?: The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.

Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?: The diameter is 60mm, but the total length of each company is not the same

Q: Is it possible to manually weld LED bulb bulbs?: As long as the welding technology clearance is possible or OK

Q: Led what's the flash of the bulb?: There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright.

Q: What brand of LED bulb is good in quality?: Look at the bulb of the bulb. The so-called bubble shell refers to the transparent glass shell in front. In incandescent lamps, all are made of glass. But in LED bulbs, though they can be made of glass, they rarely do.. Because the LED bulb weight than incandescent lamp 5 times or more, if made of glass, fell on the ground, it broke the possibility of large. As a result, more LED bulbs are made of plastic to prevent them from breaking. And the LED bulb went out because the heat from the radiator, so the bulb Everbright is visible light, infrared heating has little, so the use of plastic to make foam shell will not damage due to heat.

Q: LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: 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 achieve normal brightness, or it may damage the USB interface. It's better to use the USB charger interface. DIY needs circuit knowledge.
