Q:How many watts of LED3 is equal to the ordinary energy-saving lamps
3 w leds is equivalent to 3 w of energy-saving lamps, not so simple than power depends on photosynthetic efficiency, luminous flux and color rendering, the quality of the different products are not the same as the 4 w energy-saving lamps can replace 20 w energy-saving lamps, good product can substitute for 35 w halogen lamp cup LED is also in the same way, the 3 w can also reached the standard of 15 w incandescent lamp, lighting is not suitable for lighting
Q:How long will leds last?
Comparing to conventional light bulb is very durable. LED in general notes, can be used more than 50000 hours, and some producers to promote their LED can operate 100000 hours. The main problem is that the LED is not a simple operation, no longer its rated life cannot use traditional lamps and lanterns of measure method to calculate. In fact, when testing the LED life, no one will stay beside waiting for it to stop working. However, there are still other ways to calculate the service life of the LED. LED is lasting, because it won't produce filament fuse problem. Leds will not stop working directly, but it will gradually degraded over time. Forecasts suggest that high quality LED after 50000 hours of continuous operation, also can maintain more than 60% of the initial degree of the light. Assumes that the LED has reached its rated service life, in fact, it may still be shine, just the light is very weak. Want to prolong the service life of the LED, it is necessary to reduce or completely dispel the heat energy produced is the LED chip. Heat energy is a major cause of leds stopped working, LED the life of the related to LED chip and ELDerly drivers.
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:General how long LED desk lamp charging full of learning
Depends on the size of the battery capacity, average about 1000 ma, 4 to 6 hours is full.
Q:The led lamp low-grade why current sound
1, if appear this kind of current sound, then you buy the desk lamp of more times. Inside the power module is not very good. 2, the better the desk lamp of all is the use of constant current power supply, ensure that the service life of the lamp is longer.
Q:Led desk lamp suits, how many watts of the led lamps are very high colour temperature
The power of 1.6 W as small obviously a big gap compared with the fluorescent minimum 11 W. Now you are in the best tube is short of the brightness. Its advantage is to save electricity, if you want to look good will have to buy a 7, 8 W above.
Q:There are several major disadvantages of LED lamps
Small LED lamp bead, loss of a few years later will slowly to change, easy to cause the whole lamp scrap
Q:Led and energy-saving light which good? To solve the
7, the LED lighting technology is not so mature and complete energy-saving lamp technology. In addition, at present, the led is more expensive than price. Warm color lighting good learning? Different from common understanding, the warm color light source because of its low colour temperature, is not good for students to read or write. 5000 k and 6500 k color temperature (cool color light source) is more popular with the students, more suitable for reading, writing, etc to demand higher visual task. To meet the current criteria of classroom illumination condition, relative to the low temperature, high temperature is more advantageous to delay the visual fatigue of primary and middle school students, improve the efficiency of learning, which is consistent with foreign related research results, using ordinary in the middle and primary schools classroom much for high color temperature of the current situation of the fluorescent lamp is also consistent.
Q:Are led lamps good for eyes
A, from the perspective of electronic appliances to see: LED desk lamp, due to the light source is LED, LED is a dc light-emitting devices, theoretically to the light, the previous generations of light source with us to the light, the traditional light source such as energy-saving lamps, metal halide lamp, incandescent lamp is communication, will follow the frequency of the input current civil power grid, to change, our country is 220 v, 50 hz) of power grid, so the frequency of communication wave makes the traditional light source will appear in the stroboscope, long-term study working in this kind of light source under the eyes hurt. Use LED lamp, want to see you understand not understand, not all LED lamps are no stroboscopic, if is to use the desk lamp of rechargeable batteries, light-emitting panel does not directly see each LED lamp bead, no dazzle light is that it can until the protection for your eyes, please note that must choose surface is illuminated. Another is to use constant current power supply drive LED desk lamp, this product, you don't understand, or to find a reputable manufacturer to buy.
Q:LED lamp stroboscopic serious, can you tell me the reason?
Apparently driven problem, your LED desk lamp is the 220 ac mains voltage rectifier, stroboscopic than incandescent bulbs.
