- Q: What's the reason why LED bulb gets a lot of heat?
- If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long
- Q: Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
- Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)
- Q: Can the bulb's true life reach 30000~50000 by LED?
- The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
- Q: What's the cause of the noise during the aging of LED bulb bulbs?
- Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.
- Q: What are the requirements of the LED series inspection specification for bulb bulbs?
- Dielectric strength: electrical endurance test (resistance test) followed by insulation resistance test. During testing, the following AC voltage is applied at the specified position 1min. Type HV (220~250V); 4000V (RMS), BV (100~120V); 2U (rated voltage) +1000v.
- Q: How to identify Ic constant current LED bulb?
- Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
- Q: What advantages does LED bulb replace energy saving lamp?
- The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond
- Q: Is it possible to manually weld LED bulb bulbs?
- Well, the lights go straight up, aging, usually 24 hours of aging, testing, you have to open 10 seconds, 10 seconds off, so non-stop switching for 2 to 4 hours
- 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: Is there any flicker in the LED bulb?
- Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there. Questions raised by the questioner can show that you are observant.
