Q: Are LED lights compared to dc lights?: Basically agree with net friend in front of the answer. The desk lamp of ordinary incandescent light bulbs with energy-saving lamps, bulbs and tubes in the current is an alternating current. Incandescent lamp current is ac mains, 50 hz, on and off the 100 times per second. Filament is high temperature heating, heat capacity to a certain extent, to cool and hot, stroboscopic was not obvious, but low light efficiency, energy saving. Energy-saving lamps, is the mains ac rectifier dc, again for the high frequency inverter (several thousand Hz) communication, energy saving, stroboscopic is not obvious, not like a normal fluorescent lamp. LED desk lamp, the energy conservation, but see, on the market at present basically is a built-in battery, use mains charging can't use the lamp, can light up from the mains before, often charging more than 6 hours, often should charge, so if used in a short time is can, such as to use for light continuously over a long period of time, is not convenient. LED flashlight, with short time, it is very good. If there is no battery, do not need to charge, it is more convenient. Above for your reference.

Q: The LED lamp electrostatic test pass the corrective actions: I think the performance of the part and voltage adapter module components

Q: Charging forgot to turn off the switch, directly inserted, and then not bright,, but the charge will bright lights.. Bulb burned out or what? Can you take?: Due to the charging voltage is higher, it is burnt out, LED lights in after the LED can also be used, but more troublesome.

Q: With few desk lamp LED tile good children: Country "GB_50034-2004 building lighting design standard", the residential building lighting standard writing reading class and school building lighting standard - the surface of desk intensity of illumination should be 300 lx, light source color temperature reading class, the middle color (color is white or call sun) 3300-5300 k; Color rendering index of 80 or more; These values are based on human visual physiological and psychological data by a large number of experimental statistical summary science, can choose valuation this table lamp for reference, if the table lamp luminous surface 30-40 cm from desktop and 300 lx illumination, carry light source flux for lm (lumens) 700-700, according to the mid-range market products around 8 w and 10 w (each w90lm), remember that is not consumed power light source power, a lot of people misconstrued, 10 w consumption (input) subtract 2 w is the source power. Color warm color rendering index can't be ignored, especially the price of children eye development period of color vision culture important, many products can not meet the color rendering index (Re) of 80, more than white bluish violet color temperature with the so-called blue light pollution, increase eye fatigue. Luminous flux and color temperature, color rendering index above normal manufacturer must be marked on the nameplate or storyteller packaging. , telescopic type desk lamp if actual use away from the desktop, want to consider to increase the flux and the adjustable light, also do not have strong will accelerate the eye fatigue, finally buy anti glare (such as with opaque chimney design) products, namely children under normal posture eyes should not be directly see light or shiny surface.

Q: 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.

Q: Are sold on the market in recent years that most students rechargeable lamps with the sort of, call what name I also do not go up, anyway, not expensive, I would like to ask you about the charging lamp charging commonly how long?: Charging commonly 4 hours is full of, but don't always keep filling. Because the battery will be overloaded, it is easy to be bad. Go down for a long time, the battery power will not durable. Moreover, this will not guarantee the safety of the battery, to believe, for its own security or security charge.

Q: Of tubes is said to be good, and some say good leds, which is really good: I'm not professional, I think the lamp that shield an eye is a concept. It doesn't matter. Conditional or get a LED, more fashionable. A long service life, the power supply is not bad, can be used for the rest of your life. Strong, not easy broken. Finally is integrated packaging, light emitting area is relatively larger, and no more light of shadow.

Q: Heard that LED save electricity, to follow the fashion, a grind, spent more than three hundred bought 6 LED bulbs, but less than 3 months finished bad, all manufacturers attitude can also, all changed, but also bad, depressed.: You choose the wrong factory, general theory of LED life span is 50000 hours, the actual use also in 35000 hours. Three months is bad, is basically not well-known chip in China. Now we are doing the LED business, foreign customers require minimum is Taiwan wafer chips, and some domestic retailers order chips are the most time, because Chinese people cheat, also bad complaints after seduced. Don't mind the price to buy the philips, their quality must be guaranteed. The good and evil people mixed up domestic factory, see you luck

Q: 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.

Q: LED the desk lamp that shield an eye eye really?: Since the traditional inductive common fluorescent lamp, there will be a light blinking. Alternating current frequency is 50 hz, so common fluorescent lamp is 50 times per second periodic start-stop, due to the human eye persistence of vision effect and the effect of the fluorescent tube wall afterglow phosphor, normally would not be aware of the light blinking. But in the long-term work under this kind of light source, especially in fine operation, it is easy to produce visual fatigue and with a series of symptoms, namely, commonly known as the "eyes", so before the desk lamp of recommend the use of incandescent lamp it is for this reason. Can be fluorescent characteristics of high relative to the incandescent lamp brightness, save electricity, but can't. With the emergence of electronic ballasts, fluorescent lamp start-stop frequency from 50 hz to several - KHz, greatly reduce the flicker effect, alleviate the occurrence of visual fatigue and even can be used in a high-speed movement of the venues (table tennis, badminton) lighting, visible flicker of already fell to very low, manufacturers take this selling point and with the attractive word "eye", a little fool. Since it is not what is the role that shield an eye really, but reduce the damage to the eyes to the technology of controllable minimum. Lighting white LED, as the breakthrough after blue light LED manufacturing technology in recent years. Due to the LED light emitting diode) is a dc power supply, as long as and qualified drive power match, there is no so-called flashing, says it is "eye" a bit redundant, stir-fried concept. Every brand has a high school low-grade products, cannot treat as the same. In accordance with individual psychological orientation is good. Personal humble opinion, only supplies the reference.

The company mainly produces sales of products: LED eye protection desk lamp, LED fluorescent tube, LED ceiling lamps, LED Jane lights, LED light strip, LED bulb lamp products. Is the production of LED products are exported to Europe, the Middle East, Japan and South Korea market. Using the latest international environmental protection and energy saving technology, environmental health effects have to meet European standards.
