Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: You should say that the bulb of the bulb, usually PC material.

Q: LED thread specifications for bulb bulbs?: Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!

Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?: The chip may damp, no air humidity warehouse management process; or the chip in the assembly process by foreign influence, the lampshade is removed, and then measured once in the color of the aluminum plate radiator

Q: Can the bulb's true life reach 30000~50000 by LED?: The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.

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: What are the requirements of the LED series inspection specification for bulb bulbs?: Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.

Q: What are the characteristics of LED bulb?: Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good

Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!: Because LED's normal luminous current is 20MA, and LED has a weak current, it can emit light. According to this source. Maybe your line is just on the zero line. This will lead to a small leakage current flows through the LED lamp.Try offline.

Q: Is it possible to manually weld LED bulb bulbs?: You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off

Q: Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!: You are not the light source, in addition to a treasure bully ordinary consumers can't tell the difference between good and poor light source, all blow themselves jingyuan. I think you can see for yourself, not necessarily expensive or cheap but wafer, it certainly can not be said. Big power of a simple 1W bar, poor beads 1-3 cents, the wafer will be 1.3-2 dollars. There are several tiles, and how much does it cost?.
