Normally, we accept the complaint within one month after receipt of the goods. For some special circumstances, please kindly contact with our sales for your actual order.
- Q: LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
- Energy-saving lamps, color rendering index above 80, it has a variety of color temperature. Read a book, I suggest to use 4000 k; High color temperature advantageous to concentrate, but Dazzling; Low colour temperature of concentrate. When reading a book, lamp writes a 1.5 meters, 300-350 lux. So-called energy-saving lamps, is high frequency, otherwise, it is not energy-saving lamps.
- Q: The LED rechargeable lamps can charge while lighting? The reason?
- Desk lamp is not poor, not because of burn out, because the light and a battery, so the voltage may be no more than the battery voltage
- Q: I want to ask to buy what kind of bulb to eyes good, leds? How many watts
- I suggest you study, do not use ordinary LED lights. Because ordinary LED lights are blue and yellow light, blue light adverse to the people, and its color rendering index and low. Hello you say this kind of situation as to how many watts of specific room to install light to protect eyesight. There is no clear regulation on medicine. Guidance: But to light and shade is appropriate, not too bright nor too dark for the best. If the children often learn can buy the lamp that shield an eye The average 30 watts around the small room can use energy-saving lamps, desk lamp can be used at the same time 12 watts around the lamp that shield an eye is better. Use energy-efficient light bulbs as a lamp bulb, 7 watts is appropriate, eyes feel comfortable, but you can buy a small guard no radiation the lamp that shield an eye, the lamp no ordinary electromagnetic radiation hazard, the lamp that shield an eye dry eye not to now, the light is not dazzling light design. In general, the bright LED lights, the brightness of the 1 watt equivalent to 20 watts incandescent lamp, therefore, used as a table lamp at close range, 3 watt LED lamp brightness should be sufficient. About the color temperature, personally think that as long as you feel comfortable, but the color temperature is too high may feel dazzling, easily tired... Might as well choose between 3500 ~ 6000 ° K. 3 w, 7 w will be stabbed eyes, desk lamp advice or use energy-saving light downier, in general, color temperature of 2700-3100 is suitable, is the warm light and natural light, white light 6400 of real life, we still use more but look for a long time, eyes will sting. There is no best, only the ideal of the lamp that shield an eye is the best color rendering of incandescent lamp, color rendering index of 99 above, by contrast, it is best for your eyes, but the color temperature is too low, only 2850 k, easy to disperse. Again, it can charge. Choose Bai Zhi lamp wattage nearly 25 appropriate up to standard? ! white
- Q: LED lamp in the 4 v lead-acid battery charging problem!
- Dedicated charger generally 3 ~ 5 hours, about 200 ma small battery charging current, automatically stops charging. White led lamp voltage 3 v or so, so light is not on the discharge is lower than 3 v
- Q: LED the desk lamp that shield an eye to choose good warm light or white light is good?
- There is no white or warm white light, white light (more than 5000 k) bright point, feel good, as the object dyeing, less suitable for things looked fine, warm Bai Guangguang color yellow (below 3500 k), similar to the incandescent light, give a person with sweet feeling, suitable for one set his mind at to do something, but there are certain dyeing effect, also need not too extreme, actually can buy demitint between 4000-4500 k, with only a little yellow not had to take care of?
- Q: Long amount of led desk lamp can plug the power cord with straight?
- Cannot be used into the power supply, or light bulb will burn out internal charging power supply parts. Use notice: 1, power supply and charging socket installation should comply with the safety standards. 2, charging products do not use, so as not to burn out LED bulbs or internal charging power supply components. 3, desk lamp head not straight as eyes, lest affect vision, children should be used under the guidance of adults, do not let desk lamp in the rain or be affected with damp be affected with damp. 4, please stay away from flammable items per charge, charge time longest time can't more than 24 hours, suggest to charge in the daytime.
- Q: Led lamp is broken. Who knows what reason be? How to repair?
- There may be two reasons, one is the power source capacitance is broken, the second is one of the lights is out of question. The first reason accounted for 70%, if that's the capacitance is broken, LED lights have to change new.
- Q: When did you buy? If it is just bought, suggest you use first photoelectric charge again
- LED, LED because of the different luminous principle, eliminate the stroboscopic and has high photosynthetic efficiency and pursue higher photosynthetic efficiency potential Advantage is small volume, no stroboscopic, including UV, high light efficiency, using high quality chip (OSRAM, day, and the name of the CREE) products can reach more than 80 or 80 color and has a long life The disadvantage is that the current national standard uncertainty, the products on the market anomalies chaos, most manufacturers use inferior chip led to less than 50 color... And LED chip due to poor use drive electric power are different, such as chip array and flashing brightness difference problem In a word, If conservative and don't care under the condition of light, it is best to use halogen light source to read; Care about energy saving problem use energy-efficient light bulbs, but must pay attention to choose big, because of the small manufacturer use halogen powder phosphor color rendering index less than 70, the same is not suitable for reading; If the pursuit of high-end, strict energy-saving, wish longevity noodles and the modelling of traditional light source, can choose LED products, but the best choice in the lighting industry's top brands and formal channel, so as to the quality of the products
- Q: The lamp that shield an eye is not flashing, but changed to high frequency. Now LED lights are popular, but the use of communication to the dc LED lamp is not flashing, after all, he's a direct current is also a half wave, not straight?
- Definitely not blink doesn't exist, such as whichever refers to a kind of luminous principle, can only say that different levels.
- Q: 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
- What is your 6 v battery batteries? Small battery (battery)? 10 v charger to see what the battery charger, if the battery can work with, if nimh electricity or lithium electricity will reduce the voltage. How much is the pressure light bulb? It is best to parallel, serial word broke a are not lit up. Add how much resistance depends on what you use the lamp, or led. The dimming added potentiator current limiting. How to do is very simple, still with the figure? Charger and battery, lamps (and) series of potentiometer. If it is nickel metal hydride batteries can't do, for a long time will seriously affect the battery life in charging status. The more complex.
