Q:The led lamp low-grade why current sound
LED lamp, can use dc power supply, high frequency switching power supply, constant current drive power supply, can also use the 50 hz inductive step-down transformer rectifier power supply.
Q:LED lamp into the strip on the old flash, somehow, to teach
Lights flash that strip poor contact, the lamp power is small, so can't hear hissing "sound, the computer power is relatively larger, current is big, hissed." sound that strip poor contact; If you have the tools to open the strip to see whether the contact deformation, the whole connection piece, make can remove plug well, your problem is solved.
Q:The problem with LED charging lamps?
You can see on taobao can I recharge my core desk lamp, the great ahhh
Q:Led rechargeable lamps how to charge
Lead-acid battery charging requirement after filled with a floating time state, with the changed the user capacity and circuit design is difficult to grasp, because charging time short, filling is too long to form a rechargeable battery life shortened, theonly low-grade products without charging protection circuit, only carefully study the product description. A rough judgment
Q:LED lamp base fever is normal
Some adopts stabilized voltage supply drive leds, regulated power supply power design is critical, no allowance, also get hot. Should be choose the calorific value of the smaller good drive and regulated power supply, is more advantageous.
Q:Use LED lamp plant useful? Useful for which plants, which plants useless?
Use LED lamp plant effect is not obvious. Need a dedicated plant growth lamp. Look from the spectrum (like a rainbow of colors), the closer to the sun, the effect is best. Because the leaves of plants, and the main absorption and LanZiGuang is red light, which is why leaves many green plants. On both ends of the fluorescent lamp with a filament, inside the tubes filled with tiny amounts of argon and the thin mercury vapor, tube coated with fluorescent powder, on the wall between the two filament gas when conducting an ultraviolet, the fluorescent powder making soft visible light.
Q:The advantages and disadvantages of LED the desk lamp that shield an eye
8) adapter generally smaller than LED lights, life is short, the transformer is more easily LED the desk lamp that shield an eye main advantages as follows: (1) environmental: no pollution, no ultraviolet, infrared and thermal radiation; (2) low energy design, 150 hours of electricity once, desk lamp in the case of provide sufficient lighting, power as small as possible. Use the light source of semiconductor technology production has a very high photoelectric conversion efficiency, allows you to provide electricity, can maximum limit into light. Dc power supply, which can effectively eliminate the extra electromagnetic loss, further reducing the overall energy consumption, so the power is less than 7.5 w (3) long life light source, 10 years don't have to change the bulb, is 100 times as ordinary light bulbs
Q:The LED lamp is bad for your eyesight?
Hello, LED light source is green light source, the use of dc drive, so no energy-saving light stroboscope, can effectively prevent eye fatigue, but high color temperature of LED lights, there will be a blue light damage problem, so suggest to choose warm white or natural white LED lamps, don't choose inferior with pressure drop resistance capacity or high-pressure direct driving leds!
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:General led desk lamp how much a led lamp is usually how many watts
Generally a combination of desk lamp and lighting conditions can choose 3 w - 5 wled ball bubble lamp, high again feel too dazzling,
