Q:Baby what kind of table lamp? The LED lamp can be eye really?: Can protect your eyes, the light is primarily a stroboscopic damage to eyes, buy a desk lamp should pay attention to several problems: < ol > < li > stroboscopic, using a mobile phone or camera shot from close range luminous part, really no stroboscopic is made less than one line in the flashing < / li > < li > brightness and glare: never do desk lamp brightness is too high, about 6 to 9 w can meet the requirements of brightness, see glowing part directly, without strong dazzling, dazzling degree as small as possible < / li?

Q:I'm doing a LED desk lamp, can be through the outside light intensity automatically adjust the brightness of LED, using PWM technology, how to do excuse me: A photosensitive diode, followed by current - voltage conversion and amplifying circuit, and then sent to the AD converter, into a digital signal, for single chip microcomputer. Single-chip microcomputer according to the amplitude to send a PWM control signal to the pulse width control chip.

Q:I had had a 20 leds rechargeable lamp, then search the battery is broken, I version removed yourself to make the lamp, can directly use electrical appliances, please start: Certainly not, didn't understand such a simple truth. What are you look at the battery cell, average is 1.5 v dry cell, lithium battery is 3.7 v, and then see how sections parallel to calculate the voltage, if it is 5 v, just get a phone charger turn appliances, and then give you the lamp power supply.

Q:Three months ago I was full of electricity, this three months I was useless, now basic is full of electricity, use need not use a few hours to recharge first? Or direct charge?: 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.

Q:A led desk lamp always zi zi ring is how to return a responsibility?: Inside thrum have poor contact, look at the best, don't have accidents

Q:How many good study led desk lamp: LED lamp general 6/7 w is very bright, too light is bad for your eyes, Color temperature 4000-4000 about the most appropriate.

Q:LED the desk lamp that shield an eye eye really?: Since the traditional inductive common fluorescent lamp, there will be a light blinking. Alternating current frequency is 50 hz, so common fluorescent lamp is 50 times per second periodic start-stop, due to the human eye persistence of vision effect and the effect of the fluorescent tube wall afterglow phosphor, normally would not be aware of the light blinking. But in the long-term work under this kind of light source, especially in fine operation, it is easy to produce visual fatigue and with a series of symptoms, namely, commonly known as the "eyes", so before the desk lamp of recommend the use of incandescent lamp it is for this reason. Can be fluorescent characteristics of high relative to the incandescent lamp brightness, save electricity, but can't. With the emergence of electronic ballasts, fluorescent lamp start-stop frequency from 50 hz to several - KHz, greatly reduce the flicker effect, alleviate the occurrence of visual fatigue and even can be used in a high-speed movement of the venues (table tennis, badminton) lighting, visible flicker of already fell to very low, manufacturers take this selling point and with the attractive word "eye", a little fool. Since it is not what is the role that shield an eye really, but reduce the damage to the eyes to the technology of controllable minimum. Lighting white LED, as the breakthrough after blue light LED manufacturing technology in recent years. Due to the LED light emitting diode) is a dc power supply, as long as and qualified drive power match, there is no so-called flashing, says it is "eye" a bit redundant, stir-fried concept. Every brand has a high school low-grade products, cannot treat as the same. In accordance with individual psychological orientation is good. Personal humble opinion, only supplies the reference.

Q:The advantages and disadvantages of LED the desk lamp that shield an eye: Suggest choose dc lamp At the moment there is a kind of complex light dc the lamp that shield an eye is good, with international patent. You can keep an eye on the lamp that shield an eye the lamp that shield an eye on market and other dc: one of the most essential difference between the high frequency the lamp that shield an eye (most of the domestic brand) : China's ac 50 hz, namely change 50 times per second. So direct use of alternating current (ac) electric light, are flashing, flashing frequency is commonly 100 times per second, is the grid frequency doubling, namely change 100 times per second. Other (international brand) : the lamp that shield an eye is high frequency variations of the lamp that shield an eye, not flash. Flash badly to the human eye can't see or added a filter, take temporary solution not effect a permanent cure. LED lights: not the lamp that shield an eye. LED energy-saving lamp tube is clean and healthy, but not the real meaning of the lamp that shield an eye. The first: the lamp that shield an eye is trichromatic lamp, light color is very good; And the LED is a monochromatic light source, can have influence on the color of the eye nerve, fatigue. Although its working voltage of direct current (dc), there is no flicker problem, but because of the LED chromatography is too narrow, can't use in the place with high demand with the eye, can only be applied to general auxiliary lighting (used in exterior lighting, light boxes, etc.). Second: the lamp that shield an eye is a special fluorescent tube; LED is a semiconductor light emitting diode. Dc the lamp that shield an eye: the alternating current into direct current (dc), first with dc lamps (high technical content), no flash, no stroboscopic, real and when using the light close to natural light, very bright, but not dazzling, very soft. And other kinds of electromagnetic radiation, more the lamp that shield an eye without any radiation. Of course the price will not low.

Q:LED lamp stroboscopic serious, can you tell me the reason?: Use digital camera LED lights have similar moire interference, should be a digital camera sensor scanning frequency and multiple leds blinking frequency with a certain relationship, lead to no photosensitive sensor some particular locations and appear black stripes. According to the phenomenon that the LED lamp is resistance capacity drive is premature. In general, if the LED lights use resistance capacity device driver, then stroboscopic frequency twice of the ac power frequency, i.e., using flash frequency 50 hz alternating current while the frequency is 100 hz, with 60 hz ac for 120 hz - under the frequency, the human eye or is there a way to identify: the five fingers outstretched rapidly oscillating in the lamplight, if can see "a lot of fingers in the middle of the swing range (shadow), you can judge the LED use the low frequency pulse power supply driver. If the LED is used inverter type constant current power source, then stroboscopic frequency up to 40 ~ 200 KHZ, wiggle the fingers in this light, the human eye of persistence of vision has been unable to form such as "image of guanyin", so it can be the difference between the judgment

Q:Are led lamps good for eyes: Your problem, want to answer, the real LED lamp (from the luminous efficacy and color rendering index, dazzle light, intensity of illumination and light Angle to identify) is good for your eyes.
