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.
LED lights, sort is more, the most common of which are blue chip and yellow phosphor, this kind of light blue light is too much, cannot be used for reading. Advanced LED lights (red, green and blue), color rendering index are also more than 80, of around 4000 k. However, it is expensive.
Q:Of tubes is said to be good, and some say good leds, which is really good
Tricolor fluorescent light color soft, should be good for the eye eyesight protection. The advantage of leds is save electricity, but light is dazzling. As a desk lamp, there are a dozen of lamp is ok, wattage is too big, is not good for your eyes.
Q:The LED lamp can change the light bulb
If is the desk lamp of chip integration products, change the light bulb. (integration of desk lamp has included chips and power drive) If is common desk lamp shell, snail mouth there is filled with LED lights, it is can change the light bulb.
Q:Are LED lights compared to dc lights?
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. Leds are English light emitting diode (LED), its basic structure is an electroluminescent semiconductor chip, silver white glue or adhesive curing to the bracket, and then use silver or gold wire connection chip and circuit board, and then sealed with epoxy resin around, protect the internal core, final installation of the shell, so the LED of the seismic performance is good. Using field involving mobile phone, desk lamp, household appliances and other daily household appliances and machinery production. DC (Direct Current, DC), also known as the "constant Current power", a constant Current is a kind of Direct Current (DC), is the Direct Current (DC) are the same size and direction, it is discovered by Thomas Edison. In 1747, the United States put forward the law of conservation of charge, according to the experiment of franklin and defines the term of positive and negative charges.
Q:The child for LED the desk lamp that shield an eye myopia?
Can be very responsible to tell you, absolutely necessary. But the premise is that to choose good quality LED desk lamp. The reason: First, the LED desk lamp without uv light, this is an important one, because the uv damage to children's eyes very much. Second, no stroboscopic, the use of such a long time didn't make a child feel tired eyes. Third, high color rendering index, color reduction ability, make the child in the process of reading can more clearly distinguish the color, make the eyes more comfortable.
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:The lamp that shield an eye is after the light lamp or led the good
LED lights Lamps and lanterns of traditional power consumption not only, and will be accompanied by a large number of infrared ray, cause harm to human body, and LED lamp USES high photosynthetic efficiency conversion of LED cold light source, thus fundamentally eliminating the infrared light damage to the human eye. EFE glasses effectively restrain 35% blue light damage to the eyes. Jingdong, Tmall etc are sold. To protect your eyes.
Q:Led desk lamp suits, how many watts of the led lamps are very high colour temperature
Low-grade products in pursuit of profits must use more bad of the tube, and high color temperature, color rendering dazzling. Choose 3000 k is a little yellow, not bright. So the pipe with around 5000 k
Q:Baby what kind of table lamp? The LED lamp can be eye really?
Can protect your eyes, the light is primarily a stroboscopic damage to eyes, buy a desk lamp should pay attention to several problems: < ol > < li > stroboscopic, using a mobile phone or camera shot from close range luminous part, really no stroboscopic is made less than one line in the flashing < / li > < li > brightness and glare: never do desk lamp brightness is too high, about 6 to 9 w can meet the requirements of brightness, see glowing part directly, without strong dazzling, dazzling degree as small as possible < / li 
Q:General led desk lamp how much a led lamp is usually how many watts
With 7 w leds is enough.Long time reading or writing homework eyes not easy fatigue!
