- Q: Are LED lights compared to dc lights?
- The desk lamp of ordinary incandescent light bulbs with energy-saving lamps, bulbs and tubes in the current is an alternating current. Incandescent lamp current is ac mains, 50 hz, on and off the 100 times per second. Filament is high temperature heating, heat capacity to a certain extent, to cool and hot, stroboscopic was not obvious, but low light efficiency, energy saving. Energy-saving lamps, is the mains ac rectifier dc, again for the high frequency inverter (several thousand Hz) communication, energy saving, stroboscopic is not obvious, not like a normal fluorescent lamp. LED desk lamp, the energy conservation, but see, on the market at present basically is a built-in battery, use mains charging can't use the lamp, can light up from the mains before, often charging more than 6 hours, often should charge, so if used in a short time is can, such as to use for light continuously over a long period of time, is not convenient. LED flashlight, with short time, it is very good. Leds are English light emitting diode (LED), its basic structure is an electroluminescent semiconductor chip, silver white glue or adhesive curing to the bracket, and then use silver or gold wire connection chip and circuit board, and then sealed with epoxy resin around, protect the internal core, final installation of the shell, so the LED of the seismic performance is good. Using field involving mobile phone, desk lamp, household appliances and other daily household appliances and machinery production. DC (Direct Current, DC), also known as the "constant Current power", a constant Current is a kind of Direct Current (DC), is the Direct Current (DC) are the same size and direction, it is discovered by Thomas Edison. In 1747, the United States put forward the law of conservation of charge, according to the experiment of franklin and defines the term of positive and negative charges.
- Q: Led rechargeable lamp, charging is completed, charging indicator light color?
- There are two kinds of lamp battery: Lithium battery charge with mobile phone charge, same instructions filled with red light turns green said, such as no charging indicator can only refer to the instructions. Lead-acid batteries used in dozens of pieces of low-grade called students or children desk lamp, rechargeable light most of the products will not change color, usually from a few hours to ten hours. Lead-acid battery charging requirement after filled with a floating time state, with the changed the user capacity and circuit design is difficult to grasp, because charging time short, filling is too long to form a rechargeable battery life shortened, theonly low-grade products without charging protection circuit, only carefully study the product description. Rough judgment: try every half hour after 2 hours filling light observation (do not charge while light), and if no longer increases should be full of light is the brightest and desk lamp brightness, floating charge time same again can
- Q: Are sold on the market in recent years that most students rechargeable lamps with the sort of, call what name I also do not go up, anyway, not expensive, I would like to ask you about the charging lamp charging commonly how long?
- Charging time depends on the built-in rechargeable battery capacity and provide the size of the charging current charging circuit. General capacity/charging current multiplied by 1.2 is about the same time.
- Q: What are led lamp accessories
- USB cable, drive power panel. + 3, rechargeable, rechargeable battery, voltage regulator circuit board (rechargeable).
- Q: Someone said to 7 w is enough light It does not hurt the eyes But I go to TB, some sellers told me 3 w is enough (equivalent to an incandescent bulb 40 w) don't know that right?? ...... Would like to ask how many watts of LED desk lamp what you buy is good for your eyes? What color temperature in right? Thank you ~
- 3 w, 7 w will be stabbed eyes, desk lamp advice or use energy-saving light downier, in general, color temperature of 2700-3100 is suitable, is the warm light and natural light, white light 6400 of real life, we still use more but look for a long time, eyes will sting.
- Q: Long amount of led desk lamp can plug the power cord with straight?
- In the process of charging, charging, had better not use, or reduce battery life
- Q: The principle of LED the desk lamp that shield an eye
- The desk lamp that shield an eye is the use of no flicker, no stroboscopic, eye fatigue, not all metal texture, elegant, classic. Using high brightness and low light failure LED strips, low voltage DC12V switch type constant current drive, no stroboscopic, no radiation. Unique polarized light membrane technology, can make the LED light uniform directional output, not glare dazzling, the prevention of myopia. LED lighting now has entered the new era, a large number of LED lighting products into the family, such as LED lights, LED lights and LED desk lamp and so on family, but still have to remind the LED lighting use less as far as possible, there are blue, especially the LED the lamp that shield an eye in the trial period, LED for auxiliary lighting. Only. There are a lot of energy levels of electrons in an atom, when electrons from high level to low level transition, electron energy is reduced, and reduce the energy into a photon emission. A lot of these photons is the laser
- Q: Led lamp is broken. Who knows what reason be? How to repair?
- There may be two reasons, one is the power source capacitance is broken, the second is one of the lights is out of question. The first reason accounted for 70%, if that's the capacitance is broken, LED lights have to change new.
- Q: How many watts of led the desk lamp that shield an eye with good students
- LED lamp general 6/7 w is very bright, is too light is bad for your eyes.Have a personal 11 18 w
- Q: Folding LED touch lamp generally will be problematic
- This topic is not answer, because the LED control method are many, and the way of touch also many, control way is very much also, only from the basic principles. Caused by electric current is the main reason for the failure of light, at the same time, the LED lamps and lanterns has typical characteristics of diode (very small voltage variation, huge current change) so, LED lights control method based on current control is the best, since it is control cannot use constant current source, but to use can control constant current source. In controllable constant current source, a switch type and linear type, because the switch type is inductance as the main device, and a sharp tuning switch frequency will cause many problems, it is easy to damage the leds, controllable linear constant current source is low efficiency, but the problem is less easy to implement.
