FAQ:
1.Q:What's your payment terms?
A: T/T or L/C
2.Q:When could you send me the samples
A:2-3days
3.Q:How long is the bulk time?
A: About 8-25days
4.Q:Do you also sell other kinds led lights?
A:Yes, we also supply led bulbs, spotlights, led light, led tube light ,ceiling light etc.
- Q: LED rechargeable lamp, can you tell me how long does it take to charge for the first time?
- 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, 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.
- Q: 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.
- Q: LED rechargeable lamp charging is better
- Use light not too bright in charge, charge when there is electricity affect battery life. Nor the electricity used all forms a discharge, also affect the service life of the battery, for the average user is not very good, can only be felt light and dark in charge.
- Q: A LED light source is, but is not a plug-in, the power supply is a similar phone charger that this kind of desk lamp belongs to direct current (dc) or an alternating current, will it be a stroboscopic?
- Normal LED desk lamp not stroboscopic, this is decided by are rechargeable LED desk lamp power supply. 1, the common battery power, the power supply itself is no stroboscopic characteristics, driven by its leds stroboscopic may not happen. 2, use UBS power, UBS power is through the conversion of switch power supply dc voltage source, the voltage fluctuation is small, could not have caused the LED strobe. 3, using a dedicated dc power supply, its form has two kinds of current source and voltage source, are generally not switching power supply, stability is very good also, normally not stroboscopic. If it is found that the LED light stroboscopic explained the power supply circuit and fault, such as open circuit, LED lamp trouble light filtering capacitance.
- Q: The advantages and disadvantages of LED the desk lamp that shield an eye
- 4) light source does not contain toxic heavy metals such as tungsten, mercury. The tungsten filament in the semiconductor light source without them no fluorescent lamp, energy-saving lamp of mercury inside. (5) safety. 12 v low voltage dc power supply; No easy broken glass parts, ensure the safety of users. 36 v is the minimum voltage, can feel the body is less than 36 v power supply is safe to human body. Don't even need to 3 c certification. Dc power supply, to eliminate the high frequency alternating current (ac) of electromagnetic radiation pollution.
- Q: Baby what kind of table lamp? The LED lamp can be eye really?
- Eye lamp to brightness is appropriate, not too bright also not enough brightness, stroboscope, basic can't see the kind of eye. LED is to save electricity, and then a slant blue, the other nothing.
- Q: The principle of LED the desk lamp that shield an eye
- The LED similar principle. But the difference is that the LED is not by the electrons within the atoms jump to glow, but by the voltage on the LED on both ends of the PN junction, the PN junction itself form a level (in fact, is a series of energy levels), and then the electrons jump on this level and photon to glow. New LED display units are low power consumption, high brightness, long life, the advantages of small size, this article from the beginning of the LED display a brief history of the development of, surface-mount LED, automobile application is discussed and the development trend of LED lighting, LED to the Chinese engineers engaged in the development of display device has a certain reference value. Global the first commercial light emitting diode (LED) is made with germanium materials in 1965, its unit price is $45. In 1968, the LED research and development has made breakthrough progress, using nitrogen doping process to make GaAsP device efficiency reached 1 lumens/watt, and can emit red light, orange light and yellow light. To 1971, the industry and introduced with the same efficiency GaP green bare chip LED. Beginning in 1972 with a small amount of LED display for clock and calculator. The world's first using LED watch was initially sold in expensive jewelry store, it will cost up to $2100. Almost at the same time, HP and Texas instruments have also launched calculator with seven red LED display. In the 1970 s, due to the LED devices in the home and office equipment in a large number of applications, LED prices plummeting. In fact, the LED is the era's main text display and digital technology. However, in many commercial equipment, LED display also gradually by the fierce competition from other display technologies, such as LCD, plasma and vacuum fluorescent display.
- Q: Led energy-saving lamps are easy to break
- If there under normal circumstances, the rated voltage of electric work flow, calculated according to 5% of 10000 hours of light failure, can be used more than 60000 hours, it refers to the undead lamp (not bad not only). If it is used in the lamp above, theory can be used on more than 100000 hours, up to 20 years, but if it is used as a light source (such as LED bulbs lighting equipment), the life is small, poor, 60000 hours are very long. Is about seven years, at that time although it can shine, but the light is very weak (relatively), we say it's broken, just light has weakened, but also can bright). This is to make the LED material, generally good LED by copper plating silver bracket, good light emitting chip, with high purity gold welding, good sealing rubber seal, if it is a white LED phosphors also requires good quality, any link problems will affect the quality of leds. Of course, affect the price of it. I hope it can help you O (studying studying) O ~
- Q: LED lamp rushed into electricity, no battery is bad, but is not into electricity, charging indicator light (not bad) didn't also bright, is how to return a responsibility?
- The current charging lamp pass much, just buy a new can also, the longer the storage function will reduce in the end just charge it into electricity, problems in the internal rechargeable battery, it is no longer able to store energy so I won't charge electricity. Tell you I have a you so the desk lamp of the same, not thoroughly with the eight months, I finally changed only USES a small battery now. I can because I love electronics repair maintenance.
- Q: Are led lamps good for eyes
- Second, from the Angle of the optical to see: Traditional light source, and at the same time issued a red wavelengths of light, you can understand as invisible infrared, the over 780 - nm wavelength radiation can cause damage to the eyes, myopia are mostly indoors for a long time, too much rely on under the traditional lighting light caused by the work and study. And LED light source, mainly is the blue chip inspire yellow phosphor, the wavelength of light in between 380-780 nm, no ultraviolet and infrared light, good LED light source (note is good, you usually see in stores outside does not conform to the mostly, the current domestic exports have all the good) color rendering index greater than 85 (color rendering index, the higher the more close to natural light), have relatively full spectrum, and also is to have the green light at the same time, close to natural light, when you know a lot of treatment of myopia are to see green things, because it is depends on the green light to repair damage to the eyes, at least not add to myopia.
