Q:LED rechargeable lamp charging is better
Buy into the type of good, safe, nice hear thunder.Had better not use while charging
Q:Led lithium battery lamp, rated input current 0.5 a
0.5 A, you said is refers to the input current, voltage requirements of the charger? USB port is 5 v? If 5 v, you don't have ability to pipe the output of the charger is 0.5 A or 1 A, 2 A, 10. A, as long as the voltage is consistent, you can rest assured, when the charger voltage is 5 v, 0.5 A, 1 A, 2 A, 10 A... Refers to the charger output ability, such as 5 v2a charger, its output ability is strong, can recharge four 0.5 A LED lights at the same time, also can at the same time for the two 5 v 1 A cell phone charge.
Q:I charge the battery of LED desk lamp is broken, can put the cell phone battery received above?
If what also don't know, it's best not to casually pick up. If the battery voltage is different, it's easy to have a problem. Especially if charging voltage is higher than 4.2 V, cell phone lithium ion battery will explode, caught fire.
Q:Use LED lamp plant useful? Useful for which plants, which plants useless?
Use LED lamp plant effect is not obvious. Need a dedicated plant growth lamp. Look from the spectrum (like a rainbow of colors), the closer to the sun, the effect is best. Because the leaves of plants, and the main absorption and LanZiGuang is red light, which is why leaves many green plants. On both ends of the fluorescent lamp with a filament, inside the tubes filled with tiny amounts of argon and the thin mercury vapor, tube coated with fluorescent powder, on the wall between the two filament gas when conducting an ultraviolet, the fluorescent powder making soft visible light.
Q:I am doing an LED desk lamp,
With photosensitive components after sampling the operational amplifier amplification, then send the feedback signal input terminal of the PWM controller, light to adjust the sensitivity of the feedback signal strength by adjusting the op-amp magnification (resistance), no need for A/D converter and SCM, that is too complex, workload big cost is high. A photosensitive diode, an op-amp, a PWM controller (e.g., UC3843), plus a few resistance capacitance inductance, there are ten yuan or so.
Q:Do leds have ultraviolet radiation
No radiation, do not use LED lights, now we'll use the TCP bullying, the effect is good.
Q:I had had a 20 leds rechargeable lamp, then the battery is broken
Home appliance is 220 v ac? That obviously doesn't work, even if 20 LED series also not line, you can get a suitable small transformer, low output voltage is used.
Q:How to repair the led rechargeable small desk lamp
All is bright or not bright? If it is not all bright, check the input part is whether links of control circuit of rechargeable batteries and short circuit or open circuit;
Q:Philips lamp with good light bulb or led
LED bulbs than traditional incandescent lamp energy saving more than 80%, but the LED light source the light biological safety has not been very clear answer, see how do you choose
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!
