- Q: Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
- Common lamps and lanterns can hold the LED light bulbs, as long as the lamp holder matching. LED lights: the abbreviation of English words, the main meaning: = LED Light Emitting Diode, the light-emitting diodes (leds), is a kind of ability to electric energy into visible Light solid state semiconductor devices, it can be directly put DianZhuan into Light. Traditional incandescent lamp (tungsten lamp), high energy consumption, short service life, under the circumstances of global resources nervous, has gradually be governments it is prohibited to produce, then substitute products is electronic energy-saving lamps, electronic energy-saving lamp is more energy saving effect, but due to use a lot of environmental pollution by heavy metals, and contrary to the trend of environmental protection. With the high-speed development of LED technology LED lighting is becoming a new type of green illumination of choice. In LED luminous principle, energy-saving, environmental protection level are much better than traditional lighting products.
- Q: Led the desk lamp, electronic calendar watch how to adjust?
- In normal display MODE, press the "MODE" key respectively into the corresponding function: normal to 12 hr / 24 hr, the alarm clock - birthday reminder - timer 2.1 in normal state, press the "MODE" button to enter 12 hr / 24 hr state, then press "bring, ▼" keys 12/24 hour system transformation, press "SET" key and "bring, ▼" keys can be SET up time, date.2.2 in normal state, according to two consecutive under the "MODE" button or directly according to the "AL" button to enter the ALARM state, has "ALARM" signal display, press the "SET" key and "bring, ▼" keys can be SET up ALARM time and choose a cause ring tone, a total of 7 first music and 2 different selection of "click" sound.Press the "SET" button again to close the alarm.When the set alarm clock arrives, it will ring for one minute.If there is an open snooze function, it will ring one time every three minutes, four times.In the normal state, press the "MODE" key to the birthday alert status, press "SET" key and "target" key to SET the date and time of the birthday reminder.Press the "SET" button again to close the birthday reminder.When the birthday reminder is set, play a five-minute birthday song.2.4 under the normal state, according to four consecutive "MODE" button to enter the TIMER state, there are "TIMER" sign, press "SET" key and "bring, ▼" keys can be SET up reverse timing time, timing range: 23:59-00:00 hours.When setting time to "0:00", it will ring for 1 clock and "0:00" flicker continuously.Press any key and stop.Above 3. In normal state, the LCD screen display ALARM when the "ALARM", according to "bring" button to open/close to sleep function, the LCD screen above "SNZ" logo will display and not accordingly.In the normal state, press "enter" button to open/close the music appreciation function.When opened, 7 different music is available on the circuit.In normal state, the temperature conversion of Celsius/Fahrenheit is achieved by the "SET" key.
- Q: Led lights can use how long
- 100000 hours are brag, capacitance is short of this life, about 30000 hours
- 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: I'm doing a LED desk lamp, can be through the outside light intensity automatically adjust the brightness of LED, using PWM technology, how to do excuse me
- With photosensitive components after sampling the operational amplifier amplification, then send the feedback signal input terminal of the PWM controller, light to adjust the sensitivity of the feedback signal strength by adjusting the op-amp magnification (resistance), no need for A/D converter and SCM, that is too complex, workload big cost is high. A photosensitive diode, an op-amp, a PWM controller (e.g., UC3843), plus a few resistance capacitance inductance, there are ten yuan or so.
- Q: Led rechargeable lamp, charging is completed, charging indicator light color?
- What color is your watch before charging, then ran a period of time under observation to know, most of them are will change color. Lattice nita, photoelectric
- Q: How bright flowers LED desk lamp, good quality
- Generally see lights with LED has obvious advantages, to buy the children learning advice to wait to buy the LED lamps and lanterns, to miss the rush stages will be better. In fact, all sorts of lamps and lanterns are the national standard, as long as accord with a standard can be used.
- Q: The LED lamp can change the light bulb
- Working voltage is totally different, it is necessary to change the circuit to replace the ordinary lamp; Suggest direct purchase of LED lights to replace more practical and fast, can also practice a maintenance.
- 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: How many watts of 10 square meters of the bedroom with led bulbs Warm white or white
- As for the color temperature, I suggest that a warm white is better. Warm white can make atmosphere at home more warm oh, are you sure you don't want to work in the day a day to go home, in the cold environment and sharing family happiness!
