- Q: High-power LED the lamp that shield an eye more appropriate
- and to achieve the same intensity of illumination, white the most power-hungry, definite lamp is about three to five times the size of energy-saving lamps, LED the five to eight times. LED as its light Angle is not close to 360 degrees, under the same power, in the direction of the LED light, LED has the highest intensity of illumination, for example, if you use a 9-11 w lamp, LED lights do you completely can also use a 11-15 w energy-saving lamp as a desk lamp. Energy-saving lamps - LED 4 w power consumption calculation, turn on the light for five hours a day, continuous use of more than 50 days 1 KWH, a year only 7 degrees, 0.5 yuan per degree, only 3.5 yuan a year, but harm to your eyesight smaller, compared with 60-80 w white lamp code,
- Q: General led desk lamp how much a led lamp is usually how many watts
- Also suggested that the lamp choose warm white color temperature (3000 k), or natural white color temperature (4000 k), light color not only warm but not dazzling, long time reading or writing homework eyes not easy fatigue!
- Q: LED lamp stroboscopic serious, can you tell me the reason?
- Is zero, because ac 100 times per second of voltage is zero, if simply step-down rectifier circuit, or filter capacitance is too small, through the LED current is 100 times per second interrupt, LED is a semiconductor light emitting, reach nanosecond, response time and tungsten by electric heating filament reach the state of incandescent light emitting, filament cooling speed is about tens of milliseconds, you can turn on the LED desk lamp to see the inside of the circuit.
- 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: Long card LED charging small desk lamp
- Question 1, exactly how long is the charge? Ha ha, write on the package for 8 hours to eight hours filling bai, without packing on the accurate online said. In my experience to tell you, 6-10 hours can, usually about filling. Actually charge much less charge will only affect the service life of lead sulfate in lamp battery, lead acid battery is made of memory effect, its charge number is directly related to its service life, so full of as well. But don't forget to pull out 24 hours, so there will be no safety accidents. 2, charge how many hours to charge, charge is not enough time to influence? Already answered above, will only affect the life. Influence is very big. Suggest you fill 8 hours as well.
- Q: The problem with LED charging lamps?
- 1, if the discharge to the LED desk lamp out recharging, the battery is already in a state of over discharge, discharge will seriously affect the battery life; 2, usually, when the discharge to about 80% of the nominal voltage battery, should be used to recharge the battery. Such as: the nominal 3.7 V lithium electricity, discharge to about 3 V, must charge nominal 6 V lead-acid battery, discharge to about 4.8 V must charge; 3, LED desk lamp is very save electricity, if the battery capacity is larger, continuous discharge ability is stronger, in the process of the whole light, LED lamp brightness change also be aware of not easily, just by visual inspection, indeed not easy to decide when discharge end; The easiest way to use multimeter test battery voltage to judge whether the charge. Hope the above reply to help you.
- Q: Card lamp, LED desk lamp can take a plane
- Ride from the airport international and regional flights originating in China, those items must be filled in capacity of less than 100 ml of container, and in a capacity of no more than a liter, repeatable sealing transparent plastic bag. Every time per passenger allowed to carry only a transparent plastic bag, beyond the part should be shipped.
- Q: The service life of LED lamps and lanterns is true?
- Theory is a 30000 h - 50000 - h (semiconductor diode). 1. The chip encapsulation (not the same environment, affect the life. And the light bulb how to low the situation is not possible, this is a standard) 2. The power drive power supply (electronic products, general is 2 years,) 3. The lamps and lanterns, the whole life is a long time, generally 2 to 3 years.
- Q: Led lamp is broken. Who knows what reason be? How to repair?
- Are generally light bead is broken, you can see the lights have obvious black is bad Have a light means that you drive or current enters in the work. You see no light of lamp bead is generally bad
- Q: So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
- Line loss, it is good to connect.Of course, can also according to component model and buy a change.
