Q:The principle of LED the desk lamp that shield an eye
LED the lamp that shield an eye use LED several features: 1, the LED is constant current drive, no stroboscopic. 2, excluding infrared, ultraviolet visible light with leds. 3, LED does not produce harmful electromagnetic waves, no radiation. In fact all the leds have these features. As to whether hype, I don't do evaluation, because I also heard that LED the lamp that shield an eye for the first time, don't understand.
Q:Led rechargeable lamps how to charge
There are two kinds of lamp battery: 1. The lithium battery with mobile phone charge, same charging indicator filled with red light turns green said, such as no charging indicator can only refer to the instruction. 2. 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
Q:LED rechargeable lamp, battery voltage is how many v?
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. 1, rechargeable lamps with light emitting diode and a flashlight with should be the same. The above work should be refers to the voltage on single diode voltage. Don't know how much is the battery pressure is how even get to see that a few diode. But according to my experience, I've hurt countless this flashlight and desk lamp) 4 v battery voltage is not the batteries are lead sulfate is 6 v battery. 2, see the internal structure of light emitting diode, the bulk of the pole is negative, the light of the part is connected to the cathode, or look at like a bowl of concave portion of the attached to the cathode. 3, heard "filament" if you want to ask is "filament light source" refers to a hot filament of the bulb, tube produced by light sources; If you want to ask is "filament voltage" is refers to the added on both ends of the filament voltage. Case there is a small light bulb and a dry cell formed a closed circuit is: at the ends of the battery voltage = bulb voltage + the consumption of battery internal resistance. Usually learn high school electricity can use this relationship. 4, x ray tube, extreme conditions, the theory of complex sentence couldn't say for sure.
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:The effect of rechargeable lamps and benefits
Rechargeable table lamp's biggest advantage is that can do blackout lighting. Secondly can treat as mobile lighting, car, camping, instead of a torch, and so on.
Q:LED rechargeable lamp, what to do with the battery can't charge.
The LED rechargeable lamps When first use, adequate electricity, first when not in use, store must supplement electricity once in three months. When using battery lighting lighting obvious dim light need charge in time, otherwise it will affect the battery life. And new LED rechargeable lamps have been used while charging into consideration. New product YG - 3939 jager, YG - 3940, and so on lamp has been achieved using while charging.
Q:The LED lamp how to realize the function of adjustable brightness and color temperature?
Simple dimming can be concatenated in the LED lamp bead loop resistance, change the current, can adjust the brightness, better with adjustable brightness of PWM pulse width adjustment, circuit is more complex. Color temperature seems to be no commonly, by LED lamp bead characteristics (fixed) materials and manufacturing has decided, unable to adjust.
Q:LED small desk lamp, found that the charging indicator light is not bright, or bad?
Since it is new, then to find businesses, can ask how to use correctly.
Q:Students do homework with LED lamp to choose LED strips or LED lamp bead?
Led strips and one of the led lamp bead. Common led two or four pins, there is no needle foot, close to the circuit board copper foil welding, are the same. You should choose lamp bead the key is to consider the color temperature, color rendering index, lights, light failure, and the power of good or bad, and so on.This do not have what distinction, be honest and see you turn on the light effect, such as soft soft, color is good, fever, instability, and so on. Don't be so fastidious that, as with two.
Q:The LED lamp can use while charging?
Can, but it is not recommended to do so. Mobile phone can also charge while playing, but also have exploded. While filling in terms of electrical damage!
