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:Is there any flicker in the LED bulb?: Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there. Questions raised by the questioner can show that you are observant.

Q:LED bulb w can replace 40W incandescent lamp: D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.

Q:What's the reason for the LED bulb strobe?: Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q:What's the cause of the noise during the aging of LED bulb bulbs?: The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.

Q:What brand of LED bulb is good in quality?: What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.

Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?: Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.

Q:Led what's the flash of the bulb?: I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power problems

Q:Choose which light bulb LED bulb is the healthiest: For home use, you can select LED bulb below 8W, with a color temperature below 3500K

Q:What are the types of LED bulb?: The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.

Q:How to identify Ic constant current LED bulb?: The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
