- Q:Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
- Because incandescent lamp and electronic energy-saving lamps in People's Daily use still occupies a very high proportion, in order to reduce the waste, LED lighting manufacturers must develop in accordance with the existing interface and habits of the people are using the LED lighting products, make people don't need to replace the original traditional lamps and lanterns pedestal and lines can be used under the condition of a new generation of LED lighting products. So the LED ball steep light was born. LED ball steep light used the existing way of interface, the screw (E26 / E27 / E14, etc.), pin (B22, etc.), and even to accord with the habits of people to imitate the appearance of the incandescent light bulb. Based on LED light-emitting principle of unipolarity, designers did change in the lamps and lanterns of the structure make the LED ball steep light light distribution curve of the basic point source of convergence with incandescent bulbs.
- Q:Whether the LED desk lamp, luminous points: two guide plate and the patch?
- Guide plate is the structure of the desk lamp of a light transmission parts, and not light. The LED lamp are patch.
- Q:Non rechargeable LED lamps have a stroboscopic?
- Normal LED desk lamp not stroboscopic, this is decided by are rechargeable LED desk lamp power supply. 1, the common battery power, the power supply itself is no stroboscopic characteristics, driven by its leds stroboscopic may not happen. 2, use UBS power, UBS power is through the conversion of switch power supply dc voltage source, the voltage fluctuation is small, could not have caused the LED strobe. 3, using a dedicated dc power supply, its form has two kinds of current source and voltage source, are generally not switching power supply, stability is very good also, normally not stroboscopic. If it is found that the LED light stroboscopic explained the power supply circuit and fault, such as open circuit, LED lamp trouble light filtering capacitance.
- Q:Long amount of led desk lamp can plug the power cord with straight?
- See what kind of, is that a light, if it is r-c step-down circuit + lead-acid battery, internal voltage regulation and protection circuit, can't turn on the light, turn on the light charging will give lights to burn out, you look for the packing instructions are printed on the color card, flashlight, LED lamp will be printed with similar to turn off the lights and then charging, charging instructions, please do not use when we use the LED rechargeable flashlight, rechargeable lamps, all because of electricity used up, forgot to turn off the lights, on 220 v power directly, burn the majority.
- Q:LED rechargeable lamp, what to do with the battery can't charge.
- Plug in the charger is not bright, is likely to be failure. Check the wiring and switch. Test the charger have any voltage output.
- Q:The LED rechargeable lamps can charge while lighting? The reason?
- resistance capacity is determined the capacity of capacitance current, and the charging current is very small, generally in 1 u for many, the charging current is about 70 ma, 13, and light bead is usually a 20 ma, that is the lamp bead is 260 ma, so four hours to point to a hour, if charge while using, then charge electric light enough to use, the end result is the battery voltage drops to light bead, is about 3.2 V, that is to say the battery will discharge, after filling is filling in a difficult, because with lead-acid batteries.
- 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: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:How many good study led desk lamp
- LED lamp general 6/7 w is very bright, too light is bad for your eyes, Color temperature 4000-4000 about the most appropriate.
- 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.
