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 principle of LED the desk lamp that shield an eye
Such competitive incentive LED manufacturers to further expand their product type, and actively seek the LED application field has obvious competitive advantage. After that the LED has applied to text dot matrix display, background light grid and the map array. Digital display the size and complexity of the growing, from 2 digits to three or even four, from section 7 of figures to display complex words and design combination of 14 or 16 segment array. To provide intelligent lattice LED display manufacturers started in 1980. The advances in technology have made the LED can be used in outdoor sports information release and car central high stop lights (CHMSL) equipment installation. Highlight blue LED to the invention of the realization of image advertising display screen, the screen can display image, full-motion video image. The emergence of blue leds can make people use backward transformation of phosphorescent materials from high-energy blu-ray partially converted into other colors. Now only use LED light source can be completely cover all saturated color of CIE chromaticity curve, and all sorts of color of LED and the organic integration of phosphorus can almost any color without any restrictions. In terms of reliability, the half-life of the LED (that is, the light output was reduced to half the time of the initial value) is about 10000 to 10000 hours. Instead, small type indicating the half-life of incandescent lamp (half the half-life of here refers to the number of lamp failure time) typical values is 100000 to thousands of hours, depending on the light of the rated current.
Q:The problem with LED charging lamps?
1, if the discharge to the LED desk lamp out recharging, the battery is already in a state of over discharge, discharge will seriously affect the battery life; 2, usually, when the discharge to about 80% of the nominal voltage battery, should be used to recharge the battery. Such as: the nominal 3.7 V lithium electricity, discharge to about 3 V, must charge nominal 6 V lead-acid battery, discharge to about 4.8 V must charge; 3, LED desk lamp is very save electricity, if the battery capacity is larger, continuous discharge ability is stronger, in the process of the whole light, LED lamp brightness change also be aware of not easily, just by visual inspection, indeed not easy to decide when discharge end; The easiest way to use multimeter test battery voltage to judge whether the charge. Hope the above reply to help you.
Q:The LED lamp how to realize the function of adjustable brightness and color temperature?
Dimming color LED to absorb dome light, it is within 2 the output of the road. All the way to warm light color temperature (3000 k), all the way to cold light (white, around 7000 k color temperature). Each is independent of all the way. By giving each different brightness, all the way to the whole lamp color temperature adjustment and brightness adjustment. For example, A road is warm light, color temperature 3000 k, but only 10% of the full bright, brightness and B road is cold light, brightness is only 40% of the full bright, so, blending the color temperature in light body may be only 5000 k (there was A little warm white is not very cold, white). That is to say, the real dimming color can calibrate the brightness and color adjustments.
Q:LED small desk lamp, found that the charging indicator light is not bright, or bad?
Since it is new, then to find businesses, can ask how to use correctly.
Q:LED rechargeable lamps didn't work for too long, the result can't shine! How to do?
The LED itself damage probability is very small, only could be charge and discharge the battery out of the question!
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:How to repair the led rechargeable small desk lamp
If the part is not bright, check if not bright LED's virtual welding or burning.
Q:Hurry, common desk lamp is ac or dc output, and energy saving LED lamp?
The output ac socket After the transformer voltage between 8 v 10 v 20 v ranging from energy-saving led equivalent
Q:LED rechargeable desk lamp the internal rechargeable battery, charging voltage is how old?
Charging voltage high, will affect battery life; But some desk lamp is 6 v or 9 v battery. So it is best to open it, take the battery voltage shall prevail.
