FAQ

Long amount of led desk lamp can plug the power cord with straight?

See what kind of, is that a light, if it is r-c step-down circuit + lead-acid battery, internal voltage regulation and protection circuit, can't turn on the light, turn on the light charging will give lights to burn out, you look for the packing instructions are printed on the color card, flashlight, LED lamp will be printed with similar to turn off the lights and then charging, charging instructions, please do not use when we use the LED rechargeable flashlight, rechargeable lamps, all because of electricity used up, forgot to turn off the lights, on 220 v power directly, burn the majority.

LED small desk lamp, found that the charging indicator light is not bright, or bad?

Since it is new, then to find businesses, can ask how to use correctly.

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

With photosensitive components after sampling the operational amplifier amplification, then send the feedback signal input terminal of the PWM controller, light to adjust the sensitivity of the feedback signal strength by adjusting the op-amp magnification (resistance), no need for A/D converter and SCM, that is too complex, workload big cost is high. A photosensitive diode, an op-amp, a PWM controller (e.g., UC3843), plus a few resistance capacitance inductance, there are ten yuan or so.

How to identify what the real eye lamp?

And people accidentally touch can also cause accidental burns, it is for people with a safe hidden trouble problems. While the LED lamp will not produce this kind of situation, Angle lights lamps are doing reliability test of time, five desk lamp work for two weeks in a row, the lamp body, the highest temperature is no more than 40 degrees, most Gao Wudu than the environment temperature, from this point of view, the LED desk lamp more security than the general desk lamp. x0d third, LED desk lamp spectrum is the most close to the sun, and every day we at least half of the time exposed to sunlight, the human eye to adapt to the sun is the most, so add a light source can be infinite close to the sun, so our eyes under the influence of light will be more less, the human eye would feel more comfortable. So as to achieve the purpose of the eye!

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.

The maintenance of the charging table lamp

If need to replace the light source (light pipe), be sure to refer to LED lamp assembly for the specified parameters of the charging, and don't change the structure. LED rechargeable lamps surrounding not moisture, dust and impurities, such as have found that clean up in time. Try not to over and over again when applying the LED lamps and lanterns of switches, it can greatly shorten the service life of LED lamp. LED lamp battery charging protection is good, if need to replace please select qualified products. Charging in LED desk lamp of power recharged when finished quickly, do not run out of electricity, and then filling, please stay in xiao yu battery recharging. If long time don't have to, but after a period of time the charging time, on the ground of deposit must be put in wet places.

Energy-saving light bulbs or LED bulb can't use on the dimmer lamp holder?

High quality solutions You can. Dimmer lamp dimming principle, is to use the thyristor (SCR) adjust the conduction Angle, change the alternating current (ac) electricity time to power a light bulb, change in order to achieve the average of the power supply voltage and current, adjust the effect of light intensity. Energy-saving lamps, LED lights, there are the power transformation, all need power supply of alternating current into direct current (dc) first, and then into a high frequency ac (CFL) or dc constant current (leds) to drive a light emitting part.

What if the led lamp doesn't shine

LED lamp light is usually a lamp is broken, no inspectors according to the following steps to do. 1, before open the LED, measure the power supply voltage, and current through the LED. 2, then open it, each check all key parts: drive or power supply, LED lamp bead, change all the broken lights. 3, find out the failure reasons of LED lamp bead, if flow, immediately minish the drive current. Check whether the drive is defective, also want to find out the reason, can the trim, can't repair the replacement
