- Q: The led rechargeable lamps useless can also be used for a long time
- Can be used, but need to charge immediately, but the battery for a long time not charging, performance and life
- Q: Elementary school students with what kind of table lamp is the best? The LED lamp?
- Although I personally do LED lamps and lanterns, but I don't recommend LED desk lamp for children, and, after all, now the industry focus on blu-ray damage does not, as far as I know only a few manufacturers are doing. For child health, in energy saving at the same time can be measured and feel if I say wrong
- Q: Desk lamp with led bulbs or incandescent lamps good
- Incandescent lamp: low light efficiency, high energy consumption), ac drive No blue light damage, high color rendering index
- Q: Long amount of brand of LED desk lamp capacitor charging Fried v100uf 50
- This kind of LED desk lamp, 220 v power supply is to step down by means of capacitance current limit, once the no-load, after rectification voltage will be increased to 310 v, 220 v x under the square root of 2), seconds kill the capacitance of the withstand voltage 50 v. So this failure, you must first check whether the no-load and load of power supply circuit is normal battery, check the battery cables are broken, the charging current limiting resistor is burned, if these are no problem to check current limiting capacitance itself isn't breakdown (usually the breakdown causes 220 v over-current, empty trip meeting).
- Q: How long will leds last?
- Lifetime of the LED is very long, but the service life of LED bulbs will see the quality of power supply board, power board quality is bad life is short, LED lights have tens to hundreds of yuan, suggest to buy a real good quality, long service life.
- Q: LED the desk lamp that shield an eye the choose and buy, should consider what respect?
- Brightness, brightness is too light or too dark can cause eye fatigue, so appropriate brightness is very necessary, we suggest electrodeless lamp dimming
- Q: The lamp that shield an eye is after the light lamp or led the good
- Advantages and disadvantages each generation of light source: The first generation of light source: incandescent lamp High frequency flash, blue light, radiation, tungsten wire, pollution is small, power consumption is big. The second generation of light source: traditional fluorescent lamp High frequency flash, blue light, radiation, mercury pollution is serious, the high frequency ballast. The third generation of light source: high frequency fluorescent lamp, the lamp that shield an eye, energy-saving lamps) Low frequency, blue light, radiation, high frequency electronic ballasts, alternating current (ac) light exchange tubes produced by stroboscopic light can cause eye damage the cornea and iris, causing fatigue and decreased vision, also makes them similar neurasthenic symptom such as dizziness. The fourth generation light source: LED the desk lamp that shield an eye (brands such as: children see treasure, philips, op, good vision, good light, Ming can reach, Edward, xiao, crown) Blue light (led) unique, no stroboscopic, no radiation, has the rich lighting products, low energy, mainly used in large-scale landscape lighting. The eye effect is that use adapter output low voltage dc, basic no stroboscopic, light color temperature range can be more widely, the disadvantage is that the light of the chromatography is too narrow, and has not eliminate blue light, blue light composition is too strong, easy to cause irreversible eye disease, not suitable for high environment with its eyes. Fifth generation light source: dc the lamp that shield an eye (brands such as: after light) No light, no stroboscopic, no radiation, high price, the visibility is small, single product, the mature dc technology, using the transformation output dc dc ballast light dc lamp, lighting area is generally larger, can be applied to high environment with its eyes.
- Q: Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?
- The output ac socket After the transformer voltage between 8 v 10 v 20 v ranging from energy-saving led equivalent
- Q: LED lamp is broken, put it down, things do
- Make a 3 to 7 w drive, can directly to the utility. Of course you should guarantee the lamp bead not burn
- Q: LED lamp wattage? How much is the smallest biggest respectively?
- As long as we have consumed power have wattage! Leds are quite a number of specifications, small to 0.1 watts, large to kw. Can be used in normal indoor lighting, can also be used in outdoor lighting, is the first choice for the current lighting lamps and lanterns
