Q:The service life of LED lamps and lanterns is true?
In theory LED (single light emitting diode) life can reach 100000 hours. But after assemble into lamps and lanterns, also related to the life of the other electronic components. That is the life of the LED lamps and lanterns of less than 100000 hours might fail, is not necessarily the LED itself, it is possible that the power of the chip, electrolytic capacitor and other components out first. And now many LED manufacturers, the quality is good and bad are intermingled.
Q:The LED fluorescent lamp color temperature probably how many is the best
This is hard to generalize. Because of individual differences, habits and customs is different, also different for lighting light color temperature preferences. In general, white people prefer warm color light (2700 ~ 4000 k), the reason is that this kind of lighting light of skin appear ruddy health; Most of the yellow race like daylight color white light (5500 k) or slightly cold blue pigments, the reason is that the light appears bright.
Q:How to choose the night reading reading lamp
Not use the desk lamp of learning to read, from the point of view of energy saving, LED certainly didn't have to say, but if it is for a long time to read the desk lamp of learning and choice, from the comprehensive health lighting index evaluation, if it were not made to order, if you want to buy the perfect, it had to spend many time and money! As each light source after the revolution, the older generation of light source products because of some outstanding parameters but not completely eliminated, it seems, LED desk lamp light source as won't win all the LED light source.
Q:I buy LED lamp light moving light and shade is how to return a responsibility
LED lamp light (light shaking) generally there are two reasons: one is the direct use of alternating current drive, the lowest cost of this kind of desk lamp, it is only a current limiting resistor circuit and a set of leds, produce power frequency flicker is inevitable; Second, using the low cost of electronic transformer, circuit performance is not perfect, the LED drive power constant current effect is poor, in high frequency belch phenomenon, users will feel the light shake in light and shade
Q:LED lamp, 220 power supply what do you mean?
This is clearly can be directly inserted in the home of the socket can be used.
Q:A led desk lamp always zi zi ring is how to return a responsibility?
Poor contact After a long time aging.Poor contact After a long time aging
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.
Q:LED rechargeable lamp charging is better
Buy into the type of good, safe, nice hear thunder.Had better not use while charging
Q:Why do some led desk lamp is white light, have a plenty of take a bit of blue?
With a little bit of blue is light; LED lighting is generally warm white, is white, cold white three color; Warm white, the color of light yellow, let the human look at warmer, solid said warm white. Warm white LED lamp light like a tungsten filament bulbs before that kind of color, can be used for household lighting. Is white, the color of the light color to white light gradually, but the color temperature of light color eye look more natural, reason is called white, also called natural white. Is the color of white light like a rod daily to the light, is also used for household lighting.
Q:Desk lamp good still tube of good to buy LED strips? Search light tube usually can use a few years need to change?
A low power consumption and lower power LED that LED the working voltage of is generally 2-3.6 V. The working current of 0.02-0.03 - A. That is to say: it consumes the electricity is not more than 0.1 W. 5, green environmental protection, high efficiency and energy saving, the LED is made from non-toxic material, unlike fluorescent mercury can cause pollution, at the same time, the LED can also be reused.
