Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate

The heat sink temperature and the temperature of the radiator is not the same, the heat sink through thermal grease or other heat conducting medium to heat to the radiator, the temperature will not coincide. And the temperature inside and outside the radiator is also different.

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: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's the cause of the noise during the aging of LED bulb bulbs?

This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.

Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?

Or if there's a problem with the process, just zoom in and see!

Q:Want to find common features, unified purchase accessories repair!

Common problems, a lamp is broken, the heat is not good cause, most likely it is a bad driver. As for the aluminum substrate, it should not be bad

Q:LED how does the bulb return electricity?

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

Q:What advantages does LED bulb replace energy saving lamp?

LED lamp structure is strong, green environmental protection, not easy to destroy, long life (generally 5 years is not a problem), this is energy-saving lamps can not be compared

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb

The light effects of the three are different. Incandescent light minimum generally below 20Lm/W, the energy-saving efficiency of light in the 60-70Lm/W, the LED ball screw energy-saving lamp in the global market, the quality of the naked light in 100Lm/W, with the outside door cover will drop more than 10%.

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
