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:Will the power of the LED bulb grow longer and longer? Why?
In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.
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: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:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
The cost is too high, the latter is better than the former, with long service life, there is a need bulb welcome to Taobao fry and sales of professional manufacturers of high power LED lighting lamp.
Q:What does the LED bulb patch mean?
In order to obtain high power LED light source, high brightness, the manufacturers to power direction in LED chip and package design. At present, the LED package can withstand W power has emerged. For example, Norlux series of high-power LED packaging structure for the hexagonal aluminum plate as base (the conductive) multi chip combination. The base diameter of 31.75mm, light emitting area is located in the central part, a diameter of about mm (0.375 * 25.4), can accommodate 40 LED tube core, at the same time as the aluminum heat sink. This package uses conventional tube core combination of high density packaging, high luminous efficiency, low thermal resistance, high in light output power flow under high electric. Is a kind of promising LED solid state light source.
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:What are the driving IC used in LED bulb?
MT7930, LM3445MM do bulb bulb, the effect is also ok.
Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
Speaking of attention should be to see if the light is even, PC material there are no scratches, spots and the like. It is difficult to test the proportion of raw materials used in PC materials, which is related to the aging time of PC materials.In addition, we should pay attention to anti-static.
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.
