- 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:Of tubes is said to be good, and some say good leds, which is really good
- Tell you a data, under 30 cm of height, the desk lamp of illumination can reach 1180 lux this data is the most the desk lamp that shield an eye, fluorescent lamp or LED. Also have no who is the eyes of the lamp to read a book, so the LED light dazzling is not a problem
- Q:Led energy-saving lamps are easy to break
- Don't usually, LED lights so far is one of the longest service life, and environmental protection and energy saving, good friends said out of the blue, to see
- Q:LED bulbs can put in the desk lamp of adjustable brightness?
- Can, see you what is the desk lamp of adjusting the brightness control
- Q:Why is the largest lamp radiation?
- Traditional desk lamp because have ballast, and people generally, it's close by all said have radiation is larger. LED it has a blue light, the key is not to direct eye to light, had better choose the desk lamp of a chimney. Such as this.
- Q:General led desk lamp how much a led lamp is usually how many watts
- Generally a combination of desk lamp and lighting conditions can choose 3 w - 5 wled ball bubble lamp, high again feel too dazzling,
- Q:Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect
- Ordinary pressure drop with the silicon diode rectifier is about 0.7 V, the series circuit is higher after the voltage sharing the 0.7 V, so your LED can work properly. Can be a little bit, the pressure drop on the diode wasted energy is 0.7/3.3 = 21, see, there are twenty-one percent of the energy contribute nothing.
- Q:The led rechargeable lamps useless can also be used for a long time
- Is equivalent to ordinary emergency light put a period of time. You can use it's not a problem, if unplug Light is put out that the battery is out of date in a minute. Can replace the battery, or when there is no charging function normal use.
- Q:I want to ask to buy what kind of bulb to eyes good, leds? How many watts
- I suggest you study, do not use ordinary LED lights. Because ordinary LED lights are blue and yellow light, blue light adverse to the people, and its color rendering index and low. Hello you say this kind of situation as to how many watts of specific room to install light to protect eyesight. There is no clear regulation on medicine. Guidance: But to light and shade is appropriate, not too bright nor too dark for the best. If the children often learn can buy the lamp that shield an eye The average 30 watts around the small room can use energy-saving lamps, desk lamp can be used at the same time 12 watts around the lamp that shield an eye is better. Use energy-efficient light bulbs as a lamp bulb, 7 watts is appropriate, eyes feel comfortable, but you can buy a small guard no radiation the lamp that shield an eye, the lamp no ordinary electromagnetic radiation hazard, the lamp that shield an eye dry eye not to now, the light is not dazzling light design. In general, the bright LED lights, the brightness of the 1 watt equivalent to 20 watts incandescent lamp, therefore, used as a table lamp at close range, 3 watt LED lamp brightness should be sufficient. About the color temperature, personally think that as long as you feel comfortable, but the color temperature is too high may feel dazzling, easily tired... Might as well choose between 3500 ~ 6000 ° K. 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. There is no best, only the ideal of the lamp that shield an eye is the best color rendering of incandescent lamp, color rendering index of 99 above, by contrast, it is best for your eyes, but the color temperature is too low, only 2850 k, easy to disperse. Again, it can charge. Choose Bai Zhi lamp wattage nearly 25 appropriate up to standard? ! white

The other is the appearance, price and other external factors
