- Q:How many watts of LED3 is equal to the ordinary energy-saving lamps
- Led3 tile, led3 tile how bright, 11 w energy-saving lamp is equivalent to, energy-saving lamp wattage, how many watts of energy saving lamps, energy-saving lamps how many watts, 3 w energy-saving lamps, energy-saving lamps, how many tile home how many tile energy-saving lamps, 13 w energy-saving lamps,
- 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 that shield an eye the choose and buy, should consider what respect?
- Optical processing, due to the LED lamps are using LED chips as light source, belong to the point light source, so the reasonable optical processing technology is very necessary.
- Q:Plug-in socket 12 led small desk lamp What is its battery model, the input and output voltage of each?
- 4.5 V to 6 V dc power supply, 12 leds is divided into three groups, each group of four, in parallel, each group of string a 60 euro / 1 w resistor. Can't see the battery is to say, inside the battery is filled of sulfuric acid, general 6 v or 12 v battery will be marked above well. General is 220 v
- Q:Why is the largest lamp radiation?
- Flashing the radiation of electronic ballasts, recommended minimum and lamp bulb to keep a distance of 15 cm (electronic ballast of radiation attenuation quickly), desk lamp tubes in the largest radiation beyond the national standard 0.4 W/m2, 1000 times, at least also exceeds the national standard of more than 100 times, so banned from table lamp is too close for a long time.
- Q:LED rechargeable lamp, what to do with the battery can't charge.
- The LED rechargeable lamps When first use, adequate electricity, first when not in use, store must supplement electricity once in three months. When using battery lighting lighting obvious dim light need charge in time, otherwise it will affect the battery life. And new LED rechargeable lamps have been used while charging into consideration. New product YG - 3939 jager, YG - 3940, and so on lamp has been achieved using while charging.
- Q:Three lights in parallel, and should be how the resistance of the step-down series?
- If you are sure with 6 v battery power supply, then I suggest you use four leds, two series and then parallel, such high efficiency
- 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:Desk lamp battery charging why not directly connected light emitting LED lights
- Charging desk lamp is two to 2 v battery combination section two is 4 v battery current also big white leds optimal voltage at about 3 v Scope of work of floating + - 10% plus pressure drop a diode is just 0.7 V power 4 V - 0.7 = 3.3 thus satisfy the white LED lamp working condition No diode LED will be hot Even burned
- Q:Children lamp good choice led lamp is better
- Can, LED by natural white light bead (osram), tube made of three primary colors. Starting from protecting eyesight, try not to read for a long time, should have proper rest, look at the distance, eyes
