- Q:Small leds, charging when hear the sound of the PI PI is what circumstance?
- Is generally small damage to the battery, electric charge not sparking discharge into the battery internal crack formation. If power cuts back light can light, such as the residual power after use, there is no next time. Change the battery available in theory, but the lamp was selling point is cheap, no place to repair; Oneself know words, not expensive for a few dollars online battery, can add the postage is not cheap.
- Q:LED the desk lamp that shield an eye eye really?
- Use eye, as long as the light is a kind of damage, the difference is only the size and the third, of course, is impossible, with the eye is not light lamp of choosing a cross-eyed least damage is completely necessary, by contrast, leds regardless of the effect, efficiency, and a huge step forward in principle, is the most close to natural light in all the light source of human invention. It is believed that you have to know. Just led lights there are pros and cons, now led market good rust is not neat, the size of the brand, the price have jet lag for a few times, but as long as it is more adept or understand led people have a better method, is a choice of using high power led lamp bead light is guaranteed!!
- Q:Why do some led desk lamp is white light, have a plenty of take a bit of blue?
- With a little bit of blue is light; LED lighting is generally warm white, is white, cold white three color; Warm white, the color of light yellow, let the human look at warmer, solid said warm white. Warm white LED lamp light like a tungsten filament bulbs before that kind of color, can be used for household lighting. Is white, the color of the light color to white light gradually, but the color temperature of light color eye look more natural, reason is called white, also called natural white. Is the color of white light like a rod daily to the light, is also used for household lighting.
- Q:Non rechargeable LED lamps have a stroboscopic?
- A stroboscopic, stroboscopic degree depends on the quality of power supply. In theory, the desk lamp belongs to the direct current (dc), but after ac DianZhuan into dc, so after rectifying filtering, is not entirely direct current (dc), a part of ac harmonic superposition. Only in the battery as a power source is the real dc no stroboscopic LED light source, suggest using rechargeable LED lights.
- Q:I buy LED lamp light moving light and shade is how to return a responsibility
- LED lamp light (light shaking) generally there are two reasons: one is the direct use of alternating current drive, the lowest cost of this kind of desk lamp, it is only a current limiting resistor circuit and a set of leds, produce power frequency flicker is inevitable; Second, using the low cost of electronic transformer, circuit performance is not perfect, the LED drive power constant current effect is poor, in high frequency belch phenomenon, users will feel the light shake in light and shade
- Q:Are LED lights compared to dc lights?
- We use alternating current (ac) is a stroboscopic, is 50 times a second, but should not be visual. If you buy the dc LED lamp, there is a power saving advantages of high brightness, it can be said to be no stroboscopic, by using dc. You can buy it now, is this your smart move.
- Q:Led desk lamp and common desk lamp which is good
- The launch of the white light LED light source can form mainly consisted of 450 ~ 455 nm wavelength of the blue light stimulate phosphor powder, including lower wavelength firing ability are more strong. Usually LED lights factory within a 500 - nm wavelength control, generally is 450 ~ 455 nm or 455 ~ 460 nm, belong to the strongest radiation damage extents
- Q:Pupils to do homework with good desk lamp is yellow light or white light is good
- It is recommended to use warm color fluorescent lamp LED cold light source, the spectra of blue-green color is bigger, have very strong stimulation to the eyes, time for a long time easy to cause eye fatigue; The traditional light bulb, heat source, the spectral distribution uniform, smooth color slants yellow, soft light, but the brightness is not enough, time is long can also cause visual fatigue; Fluorescent lamp (stick), according to a different phosphor powder materials can be divided into cold light warm light, cold light lamp color white or bluish, high light, but light stimulation, according to a visual fatigue; Warm yellow light line, but the brightness of the fluorescent lamp is stable, the light is downy, using the most suitable for reading
- Q:LED bulbs, use in the home, have harm to the eyes?
- The characteristics of the LED lamps and lanterns is energy saving, high efficiency, environmental protection, long service life. And LED lights than regular incandescent light bulb more environmentally friendly. Leds have high power, low power, high power LED lamp is mainly used for outdoor lighting, indoor lighting is compared commonly small power, not too dazzling. But now the LED price is a little high, not too suggest you buy.
- 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
