- Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
- PDT flame retardant plastic, good heat dissipation, flame retardant effect, you see is not very good?
- Q: Ordinary lamp LED bulb can?
- As long as the inside of the interface is the same, for example, the E27 interface (ordinary spiral, that can be installed energy-saving lamps) installed there is no problem, LED bulb is now a lot of 110V-220V high voltage power supply, so the stability is very strong, the key is to save electricity, saving seventy percent than the energy-saving lamp, no effect, ease of use.
- Q: How to choose the bulb power?
- The basic types of bulb power are divided into two types: isolated and non isolated
- Q: What are the characteristics of LED bulb?
- LED bulb advantages: energy saving: the same brightness, power consumption for ordinary energy-saving lamps 1/4. Environmental protection: no harmful substances such as mercury, no pollution to the environment. (experts point out that mercury contained in a fluorescent energy-saving lamp can contaminate 180 tons of water sources). Economy: as a result of electricity saving, electricity costs can be reduced, and the cost of the lamps can be recovered for one and a half years. A family can save tens of thousands of yuan a month. Low carbon: saving electricity is equivalent to reducing carbon emissions. Long life: LED lamp life of 50 thousand hours, six hours a day, that is, 20 years of life. The price depends on how many watts you need, and the price varies with the wattage. Now the family uses "lightning man" led, very good, the price, quality, those are good, you can go and see. Hope to help you.
- Q: How to identify Ic constant current LED bulb?
- The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
- 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: 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 brand of LED bulb is good in quality?
- The price of these lamps is very low, but the quality is not guaranteed at all. The purpose of this article is to teach consumers to distinguish the quality of LED bulbs on the market so as not to be cheated. So, which brand LED bulb is good, choose a good brand, first of all should first understand how the quality of its products
- Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
- LED bulb lamp, are driven by a power of the ordinary small beads, driving is very simple only rectification, filtering, limiting the number of components is another large power SMD beads, this drive is more troublesome, SMT SMD components, and double plate, both have the element.
- Q: What does "A19" mean in LED A19 bulb?
- I'm studying too! There's a problem for everyone to discuss
