Q:Led rechargeable lamp, charging is completed, charging indicator light color?
It depends on your desk lamp charging circuit design. If the overcharge protection circuit, the circuit design charging is completed will change color. If charging circuit is pure, not overcharge protection, will not change color. Of course, there are overcharge protection circuit is better than not overcharge protection circuit
Q:Of tubes is said to be good, and some say good leds, which is really good
I'm not professional, I think the lamp that shield an eye is a concept. It doesn't matter. Conditional or get a LED, more fashionable. A long service life, the power supply is not bad, can be used for the rest of your life. Strong, not easy broken. Finally is integrated packaging, light emitting area is relatively larger, and no more light of shadow.
Q:The LED lamp can change the light bulb
LED desk lamp is small current is energy-saving lamp, lamp power current too big, want to use have to change very troublesome, some parts to replace. The LED desk lamp is to protect the eyes and the light bulb is 50 hz frequency of eye fatigue.
Q:LED lamp into the strip on the old flash, somehow, to teach
Used for strip after a long time, the contact piece there is deviation between, the plug of the lamp and the computer plug, its size and shape is little different, because of poor contact, slight of spark and arc, resulting in the "hiss" noise. Computer power supply is switching power supply, its adaptation wide voltage range and unstable power supply also can make the normal operation of the computer, and LED bulbs have unstable voltage, because the internal circuit has energy storage component, coupled with its low power consumption, and induced voltage, flashing would happen. Recommend replacing strip.
Q:The LED fluorescent lamp color temperature probably how many is the best
This is hard to generalize. Because of individual differences, habits and customs is different, also different for lighting light color temperature preferences. In general, white people prefer warm color light (2700 ~ 4000 k), the reason is that this kind of lighting light of skin appear ruddy health; Most of the yellow race like daylight color white light (5500 k) or slightly cold blue pigments, the reason is that the light appears bright.
Q:LED rechargeable lamp, battery voltage is how many v?
The working voltage of LED (light-emitting diode) on different materials are different. Ordinary do remind instructions with phosphorus gallium arsenide material in between 1.55 V - 1.85 V; Gallium nitride material in 1.85 V - 2.15 V, the LED is red, green, yellow, orange glow (double color LED a variety of colors to choose from. General working current is very small, about 5-10 ma (0.005 0.010 A) A -- -- -- -- --, the brightness is not very high, can not be used for lighting. Using is a kind of super high brightness LED flashlight, its working voltage is higher, generally 3.35 V - 3.65 V, working current is relatively large, at 30 ma -- -- -- -- -- 50 ma, high brightness. Above is reproduced, the following is what I write. You can also in the baidu search is known here.
Q:Elementary school students with what kind of table lamp is the best? The LED lamp?
From the perspective of the characteristics of the LED light source which has: no stroboscopic (traditional lamps and lanterns is constantly flickering just frequency are thought not to come out, this is a big damage for eyes) with the effect of eye protection, no pollution, long life, environmental protection, etc.; So it is recommended to use the LED desk lamp, but pay more attention when the choice, now LED market is chaotic quality time not neat, so when the choice is to pay more attention to the strength of LED desk lamp seller to ensure his quality and after-sale, 2 it is to see the buyer on his evaluation, 3 it is to see a few with power LED lamp price, the price is too low, not to buy. The hope can help you
Q:The LED lamp is bad for your eyesight?
I don't know how you this table lamp LED performance, but the average white LED light slants cold, as compared to that of the object under the LE in natural light color nature is soft, so as a desk lamp may not good for your eyesight. But replace other USES energy-saving lamp is very good at home
Q:What kind of light the lamp that shield an eye?
First than many energy-saving lamps and bulbs save electricity, save electricity means less calorific value, in the summer you know; Followed is the security problem, LED without glass, fall is not bad, light bulbs and energy-saving lamps have the defect, and the inside of the energy-saving lamp phosphors is toxic, human body had a wound on trouble; Other benefits are followed, the most important thing is the above two. As to move light lamp, the beginning is incandescent lamp dimming, energy-saving lamp dimming later (late structure of energy-saving lamp is not suitable for dimming, introduced some styles, are more expensive and stability, even big brands), to its current LED dimming, due to the LED is like incandescent lamp, low voltage will be dark, as bright
Q:How to charge the LED lamp
Make sure you are li-ion battery or lead acid, lithium electric light and dark are used to also go, lead-acid was at any time, then keep full electricity to save battery.
