- Q: LED dual-mode folding desk lamp on external what meaning be
- Dual mode, it is to point to can use ac and dc two modes of desk lamp power supply. Both external and internal, and ultimately to the LED lamp bead above, must be dc power supply.
- 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: 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
- Q: What are led lamp accessories
- USB cable, drive power panel. + 3, rechargeable, rechargeable battery, voltage regulator circuit board (rechargeable).
- Q: LED the desk lamp that shield an eye to choose good warm light or white light is good?
- Should choose the warm light, soft and not dazzling.Which is better than the sun warm light
- Q: LED desk lamp, the USB interface, security, will the light bulb suddenly blow up
- The LED is solid, there is no gap.Oh oh oh, that would the temperature too high chimney burned, electrical fires
- Q: Study desk lamp high-power led is more appropriate
- Preferred the desk lamp of dc, because traditional 220 v ac 50 hz residual current fluctuations, causing light stroboscopic phenomenon. Stroboscopic is easy to cause eye fatigue, vision loss, deepen myopia. And preferred light yellow light, the light is warm, warm and comfortable, stable, not dazzling. Another is to see whether there is ultraviolet (uv) radiation.
- Q: Long card LED charging small desk lamp
- Use desk lamp of 5 hours a day, a month how to use electricity. This kind of LED desk lamp is very energy. If you are only used for lighting, can answer 0 degrees, almost no electricity, electricity meters are invisible. If you want to study how much degree, the za to calculate. 12 lamp holder is 12 leds, each press 3 v, 25 ma calculation, power P = 12 * 3 * 25 = 900 mw = 0.9 W, before considering other loss, even if the power is 1 W. 1000 watts of electrical appliances use 1 hour to 1 KWH 1 KWH, the desk lamp of 1 watt 1 months use 150 hours is 0.15 KWH. So for the average person can answer 0 degrees. Do you have any questions? Can you give me a message!
- Q: LED lamp rushed into electricity, no battery is bad, but is not into electricity, charging indicator light (not bad) didn't also bright, is how to return a responsibility?
- Light is not bright, can be sure is there is something wrong with the wire or internal charging circuit has a problem. Judge fault: 1, if the line is broken, looking for businesses of the same wire, in a first try (don't have to buy wire to test), indicator is not; 2, the light is bad, but little chance (if this is the case, the battery doesn't charge into the electricity, the battery has high pressure resistance state sulfide, battery need to be repaired). 3, internal charging line fault: most likely internal CBB capacitor to boil road, need to change. For this kind of lamp, the most easily broken electronic components in the charging circuit is the CBB capacitance. Can go to the repair shop repair. Only more than 1, 3 kinds of possibility is high, the highest 3, was ruled out small battery (internal small battery) problem, because the light is not bright, batteries to electric light advocate the lamp, that the battery is resistance, capacitance resistance step-down charging circuit to charge of no-load voltage can reach more than 300 v, is impossible, and no current flows through the indicator as long as is good will on, even if the battery fully charge it into electricity, indicator light will be bright. I have a problem is battery repair instrument design engineers, can ask me, I design the battery repair instrument can repair indicator but any vulcanization of battery and charge it into electricity. There is a way to judge whether there is a current through the, is at the moment of plugged into the plug has a tiny 1 of "pa", or "chip", close to the ear, can hear, careful observation can even see tiny spark, then the CBB capacitance not bad, but the light is bad, and the battery has the possibility of sulfide. Downstairs and a brother named longsheng fushun said about the battery internal resistance and resistance capacity no-load voltage of charging circuit, considered a battery sulfide failure (charge it into electricity, indicator), but not necessarily.
- Q: With 10 v charger with 6 v rechargeable batteries used at the same time, that is used when mains mains, there is no mains automatic conversion electric battery. Three light bead is in series or parallel good? Add how much resistance? Step-down to to the charger? If I want the dimmer, should how to do, had better have circuit diagram
- If you are sure with 6 v battery power supply, then I suggest you use four leds, two series and then parallel, such high efficiency
