- Q:How to identify what the real eye lamp?
- Fourth, a good LED desk lamp and pervious to light membrane and filter membrane, usually is pervious to light membrane in order to make the LED light is more soft, and filter membrane is effective for us to filter out the harmful light ingredients, so as to achieve the health requirements. x0dLED source volume is more small, so the shape of the LED products more beautiful. LED color more rich, as long as a little combination, can change several tens of different colors.
- Q:Home to buy led desk lamp is broken? Can someone fix it?
- There are also a lot of emergency, at present is that several kinds of the most common, actually what led desk lamp is broken, this also need careful maintenance and care for at ordinary times, avoid to touch water, avoid excessive lamp switch frequently, it will affect the use of lamps and lanterns, anyhow how bad how to solve, most people do in led desk lamp is broken, is discarded, to buy one, this way is not no, since the advocating environmental protection, can repair to reoccupy is also a very good treatment.
- Q:Study desk lamp high-power led is more appropriate
- LED lamp general 6/7 w is very bright, is too light is bad for your eyes
- Q:The LED current problem? LED lamp current problem?
- Influence of LED desk lamp constant current job type electric lighting built-in dedicated drive circuit work safety circuit voltage meet (5 v) work pipe external power transmission flow LED light transmission flow always 190 ma or outside the lamp burned if can match current some power supply (5 v) against things can work more
- Q:LED rechargeable lamp, battery voltage is how many v?
- The working voltage of LED (light-emitting diode) on different materials are different. Ordinary do remind instructions with phosphorus gallium arsenide material in between 1.55 V - 1.85 V; Gallium nitride material in 1.85 V - 2.15 V, the LED is red, green, yellow, orange glow (double color LED a variety of colors to choose from. General working current is very small, about 5-10 ma (0.005 0.010 A) A -- -- -- -- --, the brightness is not very high, can not be used for lighting. Using is a kind of super high brightness LED flashlight, its working voltage is higher, generally 3.35 V - 3.65 V, working current is relatively large, at 30 ma -- -- -- -- -- 50 ma, high brightness. Above is reproduced, the following is what I write. You can also in the baidu search is known here.
- Q:How many good study led desk lamp
- LED lamp general 6/7 w is very bright, too light is bad for your eyes, Color temperature 4000-4000 about the most appropriate.
- Q:High-power LED the lamp that shield an eye more appropriate
- 1 year than energy-saving lamps use 80 KWH, take 40 yuan, really want to save money a lot. And national electricity resource gap is big, also do not encourage you to use white definite lamps. 6 w LED is very bright, but a little bit far distance of illuminance are not idle, half reading needs illuminance in 300-500 lx, far from textbooks some big power, small power from the textbook, with your eyes feel comfortable as well.
- Q: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.
- Q:What are led lamp accessories
- USB cable, drive power panel. + 3, rechargeable, rechargeable battery, voltage regulator circuit board (rechargeable).
- Q:LED rechargeable desk lamp the internal rechargeable battery, charging voltage is how old?
- Now that can tear down, can directly measure the voltage across the battery is generally a little more than 3 V, with USB 5 V charging slightly larger, it is best to 4 V or 4.2 V of mobile phone chargers.
