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:Led the desk lamp that shield an eye how to choose?
Eye protection is our life lessons, eye to start at a young age. Students in rapid growth stage, the body should protect the pair of the window to the soul. Eye can reflect on a lot of details, the lamp that shield an eye can greatly alleviate eye fatigue, protect your eyes from harm. The lamp that shield an eye is not adjust light brightness, who can adjust the brightness of the lamp that shield an eye eye function. Is the price is more expensive than ordinary ordinary incandescent bulbs. The lamp that shield an eye lamp luminous color temperature value determines the degree of light is downy, high and low are not good, is suitable for 4000 k to 5200 k. The lamp that shield an eye of 4000 k to 4500 k, the light is slightly red, more soft, suitable for primary school students; And 4500 k to 5200 k color temperature value is suitable for middle school students and its older customers to use. There is good, had better choose light yellow lights for under the yellow light will feel soft and comfortable to read and write, by reading in white, for a long time will feel sore eyes. The choice of the desk lamp that shield an eye still depends on the brand, good brand of the lamp that shield an eye quality guaranteed, the quality is qualified through inspection
Q:Low voltage LED desk lamp belongs to the scope of 3 c certification
See were independent of a body or power supply Independence is the power to do 3 c lamp don't have to do
Q:Plug-in socket 12 led small desk lamp What is its battery model, the input and output voltage of each?
USB charging desk lamp is a desktop or laptop computer USB mini rechargeable lamps. Is through the computer connected to the computer USB interface, downy light, most of the charging desk lamp can adjust the brightness of the light, two control as you need to change, is very convenient. The USB port on the computer (that is, everyone is used to insert USB interface) for external voltage of 5 v power supply for the equipment, the current 500 ma, USB charging small desk lamp of desk lamp is with USB interface to provide power supply, lamp take up the space is not too much, and very save electricity, suitable for office workers or students.
Q:How many watts of led the desk lamp that shield an eye with good students
LED lamp general 6/7 w is very bright, is too light is bad for your eyes.Have a personal 11 18 w
Q:The child for LED the desk lamp that shield an eye myopia?
Suitable for LED lights, LED lights because of its long service life, green environmental protection, light is similar to the sun and around the world in promoting, at present has universal some European and American countries. Qualified LED lights line pure, high color rendering index, long life, and due to its nature of the light emitting diode, a direct current power supply must be used to work, it's essentially determines its no radiation, no stroboscopic, is a real eye light source.
Q:What kind of USB power adapter for a LED light source is a USB power supply lamp?
On the market to buy the USB power supply, the output voltage 5 v dc, can plug in the USB lamp, power supply directly.
Q:LED lamp general 6/7 w is very bright, is too light is bad for your eyes
Charging circuit disconnection or the charger itself has a problem
Q:The lamp that shield an eye is after the light lamp or led the good
Advantages and disadvantages each generation of light source: The first generation of light source: incandescent lamp High frequency flash, blue light, radiation, tungsten wire, pollution is small, power consumption is big. The second generation of light source: traditional fluorescent lamp High frequency flash, blue light, radiation, mercury pollution is serious, the high frequency ballast. The third generation of light source: high frequency fluorescent lamp, the lamp that shield an eye, energy-saving lamps) Low frequency, blue light, radiation, high frequency electronic ballasts, alternating current (ac) light exchange tubes produced by stroboscopic light can cause eye damage the cornea and iris, causing fatigue and decreased vision, also makes them similar neurasthenic symptom such as dizziness. The fourth generation light source: LED the desk lamp that shield an eye (brands such as: children see treasure, philips, op, good vision, good light, Ming can reach, Edward, xiao, crown) Blue light (led) unique, no stroboscopic, no radiation, has the rich lighting products, low energy, mainly used in large-scale landscape lighting. The eye effect is that use adapter output low voltage dc, basic no stroboscopic, light color temperature range can be more widely, the disadvantage is that the light of the chromatography is too narrow, and has not eliminate blue light, blue light composition is too strong, easy to cause irreversible eye disease, not suitable for high environment with its eyes. Fifth generation light source: dc the lamp that shield an eye (brands such as: after light) No light, no stroboscopic, no radiation, high price, the visibility is small, single product, the mature dc technology, using the transformation output dc dc ballast light dc lamp, lighting area is generally larger, can be applied to high environment with its eyes.
Q:LED desk lamp, very bright, when buy later with more and more dark
May be there is a LED lamp bead the leakage fault happens, the first thought that all leds are connected in parallel, and then string a current limiting resistor, so if there is a leakage, the overall current will increase, lead to partial pressure increases, resistor LED voltage drop, when the LED thoroughly after short circuit, all the LED all the electricity, so there is no light. Although the LED life is very long, but in fact, the life of the LED and no imagination in so long, especially high brightness tube, electrostatic breakdown them easily.
