Q: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.
Q:Led lamp generally not transformer, why also said some led desk lamp radiation levels
Some led lights use switch power supply So the excess radiation
Q:LED lamp is broken, put it down, things do
Using the multimeter, diode first gear test lamp bead is damaged. Then find a chip, CL BP OB or PI, NXP driver chip both at home and abroad, and design a constant current drive power supply. Of course also need to look at your desk lamp lights, string and how. General desk lamp is the output of 0.3-0.35 - A, your driver can be designed so that the output current.
Q:Desk lamp good still tube of good to buy LED strips?
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.
Q:Pupils to do homework with good desk lamp is yellow light or white light is good
Do your homework with white light lamp, room lamp with yellow light, this is the most close to natural light, best to protect the child's eyes
Q:LED lamp stroboscopic serious, can you tell me the reason?
Is zero, because ac 100 times per second of voltage is zero, if simply step-down rectifier circuit, or filter capacitance is too small, through the LED current is 100 times per second interrupt, LED is a semiconductor light emitting, reach nanosecond, response time and tungsten by electric heating filament reach the state of incandescent light emitting, filament cooling speed is about tens of milliseconds, you can turn on the LED desk lamp to see the inside of the circuit.
Q:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
This seems not, but can be modified, specific how to operate, can go to the shenzhen LED lighting look at technical articles on net
Q:LED desk lamp and ordinary lamp which good?
Pro. If an ordinary lamp what LED bulb lamp? At present all the desk lamp of light source (with the lamp body separation) are all common desk lamp, and its applicability is can be replaced any type of light source, including LED, and class integrated light source (lamp and light source not change) in theory the obvious advantages of LED, but in mainland China LED desk lamp is filled with a lot of bad product shoddy, that you might as well buy ordinary, should be relatively common desk lamp is cheap, and the light source is easy to change.
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:I charge the battery of LED desk lamp is broken, can put the cell phone battery received above?
If what also don't know, it's best not to casually pick up. If the battery voltage is different, it's easy to have a problem. Especially if charging voltage is higher than 4.2 V, cell phone lithium ion battery will explode, caught fire.
