22 what is the power of the led lamp charging desk lamp v
General LED rechargeable lamp power is 4 v aluminum acid storage battery.I hope you can help me
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.
How to maintenance of led desk lamp filled in no electricity
Possible battery charging circuit is broken, seeing you is what buck circuit, if it is a transformer or resistance and capacitance step-down circuit is relatively simple, maintenance is a electronic components, slightly understand electronic knowledge can repair myself. If it is switch power supply is trouble to repair, to professional maintenance technology to repair.
Led lithium battery lamp, 0.5 a rated input current search. With the output of 1 a charger or mobile power no problem?
0.5 A, you said is refers to the input current, voltage requirements of the charger? USB port is 5 v? If 5 v, you don't have ability to pipe the output of the charger is 0.5 A or 1 A, 2 A, 10. A, as long as the voltage is consistent, you can rest assured, when the charger voltage is 5 v, 0.5 A, 1 A, 2 A, 10 A... Refers to the charger output ability, such as 5 v2a charger, its output ability is strong, can recharge four 0.5 A LED lights at the same time, also can at the same time for the two 5 v 1 A cell phone charge.
With 10 v charger with 6 v rechargeable batteries used at the same time, that is used when mains mains, there is no mains automatic conversion electric battery. Three light bead is in series or parallel good? Add how much resistance? Step-down to to the charger? If I want the dimmer, should how to do, had better have circuit diagram
6 V battery should use free WeiHuXing 4 ah lead-acid batteries, the charging voltage should be 7.2 V ~ 7.5 V, and to have full automatic protection function. Can't use 10 v charger. Don't know what LED lights you choose? The working current? Positive pressure drop? These have a connection and choose the series resistance and the dimming.
The LED lamp electrostatic test pass the corrective actions
I think you the electrostatic distance from control circuit to leds this recent, one is in the line where the sliver, the second is the detection circuit chip input port less resistance and capacitance, let the minimum electrostatic effect on circuit,
How about the LED the lamp that shield an eye, ok
The lamp that shield an eye does not recommend the use of LED, LED color temperature above 5000 k more, eyes are the most comfortable the best color temperature between 3500-4300 k, using leds to do the lamp that shield an eye too tired eyes. Recommend the use of three primary colors of eye hair yellow color of the brand
Elementary school students with what kind of table lamp is the best? The LED lamp?
From the perspective of the characteristics of the LED light source which has: no stroboscopic (traditional lamps and lanterns is constantly flickering just frequency are thought not to come out, this is a big damage for eyes) with the effect of eye protection, no pollution, long life, environmental protection, etc.; So it is recommended to use the LED desk lamp, but pay more attention when the choice, now LED market is chaotic quality time not neat, so when the choice is to pay more attention to the strength of LED desk lamp seller to ensure his quality and after-sale, 2 it is to see the buyer on his evaluation, 3 it is to see a few with power LED lamp price, the price is too low, not to buy. The hope can help you
