- Q:Small leds, charging when hear the sound of the PI PI is what circumstance?
- There is a virtual place leakage or unstable power supply contact, don't take place contact line virtual to real, it is easy to burn out.
- Q:I want to ask to buy what kind of bulb to eyes good, leds? How many watts
- I suggest you study, do not use ordinary LED lights. Because ordinary LED lights are blue and yellow light, blue light adverse to the people, and its color rendering index and low. Hello you say this kind of situation as to how many watts of specific room to install light to protect eyesight. There is no clear regulation on medicine. Guidance: But to light and shade is appropriate, not too bright nor too dark for the best. If the children often learn can buy the lamp that shield an eye The average 30 watts around the small room can use energy-saving lamps, desk lamp can be used at the same time 12 watts around the lamp that shield an eye is better. Use energy-efficient light bulbs as a lamp bulb, 7 watts is appropriate, eyes feel comfortable, but you can buy a small guard no radiation the lamp that shield an eye, the lamp no ordinary electromagnetic radiation hazard, the lamp that shield an eye dry eye not to now, the light is not dazzling light design. In general, the bright LED lights, the brightness of the 1 watt equivalent to 20 watts incandescent lamp, therefore, used as a table lamp at close range, 3 watt LED lamp brightness should be sufficient. About the color temperature, personally think that as long as you feel comfortable, but the color temperature is too high may feel dazzling, easily tired... Might as well choose between 3500 ~ 6000 ° K. 3 w, 7 w will be stabbed eyes, desk lamp advice or use energy-saving light downier, in general, color temperature of 2700-3100 is suitable, is the warm light and natural light, white light 6400 of real life, we still use more but look for a long time, eyes will sting. There is no best, only the ideal of the lamp that shield an eye is the best color rendering of incandescent lamp, color rendering index of 99 above, by contrast, it is best for your eyes, but the color temperature is too low, only 2850 k, easy to disperse. Again, it can charge. Choose Bai Zhi lamp wattage nearly 25 appropriate up to standard? ! white
- Q:The LED rechargeable lamps can charge while lighting? The reason?
- Desk lamp is not poor, not because of burn out, because the light and a battery, so the voltage may be no more than the battery voltage
- Q:Folding LED touch lamp generally will be problematic
- This topic is not answer, because the LED control method are many, and the way of touch also many, control way is very much also, only from the basic principles. Caused by electric current is the main reason for the failure of light, at the same time, the LED lamps and lanterns has typical characteristics of diode (very small voltage variation, huge current change) so, LED lights control method based on current control is the best, since it is control cannot use constant current source, but to use can control constant current source. In controllable constant current source, a switch type and linear type, because the switch type is inductance as the main device, and a sharp tuning switch frequency will cause many problems, it is easy to damage the leds, controllable linear constant current source is low efficiency, but the problem is less easy to implement.
- Q:LED lamp, adjustable light, new to buy less than a week; Strip, it took more than 4 years. This morning on the strip, light will flash. To strip of the others will be fine. But the same old jack plug in the computer, but everything is normal, but the strip will issue "hissing" sound. Supposedly the lamp power is smaller than a computer, this is how to return a responsibility? I think baidu has said strip contact.
- You have the phenomenon of poor contact strip inside It is ok to exclude poor contact
- Q:How many good study led desk lamp
- Last year I bought her son a 7-day's, now take down the feeling is very good
- Q:Card lamp, LED desk lamp can take a plane
- Look at the battery storage is not too large should be ok
- Q:Led lamp, good point light source or surface light source
- Desk lamp to see is to choose lamp holder types use the bedroom or in the study, the study USES led is very good choice, monochromatic light color cold light source, can help clear your mind to learn reading; But the bedroom use or suggest using incandescent lamp, mild color, adjust the mood to sleep. Get to the point, it is recommended to use surface light source, light area is larger, help reading and prevention of myopia.
- Q:Why my desk lamp light will keep the cell phone camera shows and white flashing light and shade stripes
- Is PWM pulse width modulation technology, that is, by adjusting the light of a period of time to adjust the brightness, if the PWM frequency is high enough, can people see not to come out. Twinkle is harmful to the eyes, I only know that frequency should be no problem, because the fluorescent lamp is high frequency electronic ballasts.
- Q:Do LED lamps really protect your eyes?
- Just a slogan, not for a long time on the light.If choose when must pay attention to the surface light source
