- Q:New LED lamp USES "magnetic -" the voice from time to tome, how to eliminate the noise?
- Immediately change demand manufacturer to you, do not use the circuit pressure out of the question, you can understand for the power supply circuit is out of order, continuous use may cause a fire may!
- Q:Charging forgot to turn off the switch, directly inserted, and then not bright,, but the charge will bright lights.. Bulb burned out or what? Can you take?
- Due to the charging voltage is higher, it is burnt out, LED lights in after the LED can also be used, but more troublesome.
- Q:Three months ago I was full of electricity, this three months I was useless, now basic is full of electricity, use need not use a few hours to recharge first? Or direct charge?
- Make sure you are li-ion battery or lead acid, lithium electric light and dark are used to also go, lead-acid was at any time, then keep full electricity to save battery.
- 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:What led small desk lamp general battery
- If bought from the market, it mostly lead-acid battery, the battery is rechargeable, a wide range of application, the cost is low, but with memory effects. Some high-grade lithium battery, the battery energy density is high, the performance and life are better than the former
- Q:Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect
- See what the battery, the normal pressure drop of white LED is controlled in 2.8 3.6 V, if use lithium battery 3.7 V voltage is a little high, if he does not limit current will be very big, LED immediately to turn the raw materials.
- Q:The maintenance of the charging table lamp
- Household appliances maintenance led rechargeable lamps? Many users haven't noticed that some users will be LED rechargeable lamp is like electricity used up until then recharging it when you are going to use it. LED rechargeable lamp light life is compared commonly, if it is not because the excess voltage or short circuit, usually don't burn out.
- Q:I want to ask to buy what kind of bulb to eyes good, leds? How many watts
- I suggest you study, do not use ordinary LED lights. Because ordinary LED lights are blue and yellow light, blue light adverse to the people, and its color rendering index and low. Hello you say this kind of situation as to how many watts of specific room to install light to protect eyesight. There is no clear regulation on medicine. Guidance: But to light and shade is appropriate, not too bright nor too dark for the best. If the children often learn can buy the lamp that shield an eye The average 30 watts around the small room can use energy-saving lamps, desk lamp can be used at the same time 12 watts around the lamp that shield an eye is better. Use energy-efficient light bulbs as a lamp bulb, 7 watts is appropriate, eyes feel comfortable, but you can buy a small guard no radiation the lamp that shield an eye, the lamp no ordinary electromagnetic radiation hazard, the lamp that shield an eye dry eye not to now, the light is not dazzling light design. 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. 3 w, 7 w will be stabbed eyes, desk lamp advice or use energy-saving light downier, in general, color temperature of 2700-3100 is suitable, is the warm light and natural light, white light 6400 of real life, we still use more but look for a long time, eyes will sting. There is no best, only the ideal of the lamp that shield an eye is the best color rendering of incandescent lamp, color rendering index of 99 above, by contrast, it is best for your eyes, but the color temperature is too low, only 2850 k, easy to disperse. Again, it can charge. Choose Bai Zhi lamp wattage nearly 25 appropriate up to standard? ! white
- Q:Led desk lamp suits, how many watts of the led lamps are very high colour temperature
- The more expensive kind of have the diffuser plate, similar to large screen LED backlighting, so look more even not searching eyes
- 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.
