Q:LED bulb with what type of LED beads?

The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.

Q:Secret LED bulb bubble price difference why so big?

Remember, cheap, no good goods, the market price of less than 15 yuan bulb said that their quality is not credible.

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:What is the AC voltage of the LED bulb?

The AC voltage of LED bulb is usually 220V, and the power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.The biggest market for LED bulb lighting is the civilian market, and the LED bulb is a new green light source to replace the traditional incandescent bulb. LED lamp has the advantages of energy saving, environmental protection, long service life, no stroboscopic, green and so on.

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: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 the bulb is flashing. What's wrong with it? How do you fix it?

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!

Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!

The milk white paint can't see light, but the transmittance is only eighty percent a few. At present, the market has not seen in line with the economic benefits of such LED ball bubble glass cover, can reach ninety percent transmittance. If any brother finds it, please let us know. We also want it very much. Oh, thank you.

Q:LED how does the bulb return electricity?

A 0 ohm resistor with a large point on the negative electrode

Q:LED bulb bulbs, do you need 3C certification now?

Simple bulb does not require 3C or CQC certification.Only with lampholders, and then judge according to the situation.
