Household led lights all of a sudden not bright? What's the matter?
- If it is suddenly not very bright, usually because of its heart - LED drive power quality problems, the result of current is not enough. You can open it and have a look at the LED string, and power, to find a professional power supply company with power supply, diy connected the input and output line. If the trouble is returned to the manufacturer maintenance, this problem should be something for manufacturers. If it is used with the not so bright, like how did not suddenly don't bright, quality problem is LED lamp bead, light failure is too big. If a lamp is on there are a lot of small lights bead is unlikely this case maintenance, cost and the cost is too big, can only be changed directly. If it is only a high-power lamp bead and COB encapsulation of LED, don't bother you also can buy back to transfer the lamp bead.s
LED rechargeable desk lamp the internal rechargeable battery, charging voltage is how old?
- Charging voltage high, will affect battery life; But some desk lamp is 6 v or 9 v battery. So it is best to open it, take the battery voltage shall prevail.s
Small leds, charging when hear the sound of the PI PI is what circumstance?
- There is a virtual place leakage or unstable power supply contact, don't take place contact line virtual to real, it is easy to burn out.s
Mid-december, folded - 924 led charging desk lamp, the eyes?
- To see from the Angle of optical: traditional light source, including the red wavelengths of light, you can understand as invisible infrared, the over 780 - nm wavelength radiation can cause damage to the eyes, myopia are mostly indoors for a long time, too much rely on under the traditional lighting light caused by the work and study. And LED light source, mainly is the blue chip inspire yellow phosphor, the wavelength of light in between 380-780 nm, no ultraviolet and infrared light, good LED light source (note is good, usually see in stores outside does not conform to the mostly, the current domestic exports have all the good) color rendering index greater than 85 (color rendering index, the higher the more close to natural light), have relatively full spectrum, and also is to have the green light at the same time, close to natural light, a lot of time to treat myopia are to see green things, because it is depends on the green light to repair damage to the eyes, at least not add to myopia.s
The service life of LED lamps and lanterns is true?
- In theory LED (single light emitting diode) life can reach 100000 hours. But after assemble into lamps and lanterns, also related to the life of the other electronic components. That is the life of the LED lamps and lanterns of less than 100000 hours might fail, is not necessarily the LED itself, it is possible that the power of the chip, electrolytic capacitor and other components out first. And now many LED manufacturers, the quality is good and bad are intermingled.s
The LED rechargeable lamps can charge while lighting? The reason?
- Don't use as much as possible. Not LED burned, but may cause electrical shock. The lamp with capacitive reactance of capacitor step-down charging, lead battery energy storage. Once leakage, will be the 220 v mains by conduction electrolyte to turn on the light in the hand, have life risk. Burn out leds are still in the second.s
Energy-saving light bulbs or LED bulb can't use on the dimmer lamp holder?
- When turned on the dimmer file, after the dimmer switch power supply, with little distinction between alternating current (ac) and direct, so you can normal lighting energy-saving lamp or LED lamp.
