- 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
- 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: 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: Will the power of the LED bulb grow longer and longer? Why?
- The LED bulb does not become more powerful for extended periods of time.As LED chip light emitting device of the PN junction has a negative temperature characteristic: with the increase of temperature, the conducting voltage drop caused current rise, therefore, when the LED bulb is lighted with the temperature rise of power consumption will be increased. But good circuit and parameter design can reduce the influence of this temperature.
- Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?
- The diameter is 60mm, but the total length of each company is not the same
- Q: Led what's the flash of the bulb?
- I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power problems
- Q: What brand of LED bulb is good in quality?
- View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.
- Q: What's the difference between a glass cap for a bulb and a PC hood?
- Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.
- 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: How did the trademark on the LED bulb go up?
- And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
