Q:Seeking the production process of LED bulb... Thanks
First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
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 what's the flash of the bulb?
The internal drive of a cheap LED bulb is generally a resistance drop, and voltage fluctuations can occur in a flash. So all 100 of you are a flash.
Q:Ordinary lamp LED bulb can?
It should be clear, your point is before the lamp lights inside what, from the rectifier? LED bulb is mostly with drive, if there is no self rectifier lamp light, the best is the bulb is directly connected to the E27/E14/B22 lamp, LED lamp or light source has a good energy saving effect, mercury free lead-free, no stroboscopic, energy than traditional fluorescent lamp 80%
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!
Can reach 90% of the light, can not see the inside of the lamp
Q:How does the LED bulb look good or bad?
A light source, two power supply, three workmanship.Online shopping, I strongly suggest that you buy some reliable.
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:LED how does the bulb return electricity?
A 0 ohm resistor with a large point on the negative electrode
Q:What's the reason why LED bulb gets a lot of heat?
LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different
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.
