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 what is a good person 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 with a better future 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.

Q: Where can LED bulb be used?: Led bulb is now commonly used in civil products, is the most is a spherical bulb

Q: Seeking the production process of LED bulb... Thanks: 10 points, Baidu wants to be a LED engineer. LZ is a real budget man

Q: LED how does the bulb return electricity?: maybe because Make the question clearWhat is the return current?

Q: LED bulb w can replace 40W incandescent lamp: I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.

Q: Are there any differences between negative ion bulb and LED bulb?: The negative ion belongs to bullshit type, the concept of things!

Q: Will the power of the LED bulb grow longer and longer? Why?: In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.

Q: Detailed description of LED bulb lamp: Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes

Q: Is there any flicker in the LED bulb?: That should be a combination of small power and multiple LED lights! The main reason is the strobe power problem, to tell the truth, I do not set the LED power supply, improvement in the well to be unable to give you much help, our production of LED products, the procurement of materials and parts suppliers will request strobe or in the power supply design problem, if you want to buy LED products, especially is the bulb, I suggest you buy a large power assembly (i.e., the shell is Aluminum Alloy)!

Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: Depending on your application and cost, there's no way to say which is absolutely good;If the occasion is appropriate and the cost is not urgent, buy a drive.
