Energy-saving: low power consumption, low degradation, save up to 80% energy
Efficient heat dissipation
Long lifespan(more than 35, 009 hours)

Q: Led lights can use how long: This LED lamp bead and heat dissipation And processing technology. Do good can reach 80000 hours Even 100000 hours. Finished the test last week Accelerated aging 3000 hours A 25% drop in flux.

Q: Amount for the LED - 666 desk lamp can use charging time: Strictly speaking, it is best not to use when charging. Because: 1. Easy to get an electric shock. 1. Affect the service life of the product.

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: Led charging folding desk lamp it can directly plug: Charging desk lamp is LED (Light Emitting Diode) the desk lamp of the light-emitting Diode as Light source, with lithium battery and USB charging function, the LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light.

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: Someone said to 7 w is enough light It does not hurt the eyes But I go to TB, some sellers told me 3 w is enough (equivalent to an incandescent bulb 40 w) don't know that right?? ...... Would like to ask how many watts of LED desk lamp what you buy is good for your eyes? What color temperature in right? Thank you ~: 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.

Q: LED the desk lamp that shield an eye the choose and buy, should consider what respect?: Now is better the desk lamp that shield an eye to choose the low voltage dc power supply, safe, no electric shock hazard Cold light source options, select light source, high brightness, high luminous efficiency/low energy consumption, no ultraviolet and infrared radiation. Also need to consider the color rendering index of lamps, light color rendering index is 100, color rendering index of desk lamp, the more close to the sun color rendering index, adaptable people eyes, eyes, vision health. With and without glare is also an important standard, because dizzy light is one of the important reasons of causing visual fatigue, can choose light measurement, the desk lamp of surface light source, because traditional desk lamp can directly see light point, more dazzling, side light can't see the markers, the light is downy, uniform. Select the adjustable brightness or color temperature LED the lamp that shield an eye, because of different scenarios, different weather, the brightness of the light or there will be a certain color temperature, on-demand light distribution, science more eye. (I had to use of the lamp, can consider)

Q: Led lamp generally not transformer, why also said some led desk lamp radiation levels: There will be no frequency transformers high-frequency transformer (a lot of switch power supply are to be used), and high frequency transformer has radiation. If there is a low frequency transformer (it does not need to high-frequency transformer) but not excessive radiation

Q: The LED lamp can change the light bulb: Working voltage is totally different, it is necessary to change the circuit to replace the ordinary lamp; Suggest direct purchase of LED lights to replace more practical and fast, can also practice a maintenance.

Q: Somehow, the light is not bright, charging for a long time or not. Why can't the lamp charging while use?: Suggested to change the battery. LED rechargeable lamp charging circuit is simpler, less damage, the battery is not usually in electricity is pure battery failure. So suggest replace the battery.
