- Q:Use LED lamp plant useful? Useful for which plants, which plants useless?
- In general, grow leaves, red light demand is big, the be fond of of different plants will differ slightly. Do not have the distinction of good or bad, the key see you kind of plants. Blue light, and is good for some plants flowering. It is common used red light blue light match up.
- Q:The LED current problem? LED lamp current problem?
- Power supply voltage will not have an impact on power electronics, electrical appliances it needed current from power supply only, will not change because of the size of the power supply current.
- 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:Low voltage LED desk lamp belongs to the scope of 3 c certification
- See were independent of a body or power supply Independence is the power to do 3 c lamp don't have to do
- Q:The effect of rechargeable lamps and benefits
- And the benefits of a little-known, rechargeable lamps often can charge, by the way, when use rechargeable batteries like a giant filter capacitor. 50 hz ac mains through bridge pile rectifying become 100 hz dc pulse current drive light work, if the filter capacitor is too small, dc power supply will be pulse ripple, Taiwan will flash light frequency of 100 hz. Have the battery, filtering effect to perfect, to the nearest basically eliminated the problem lamp strobe, the desk lamp that shield an eye than other parity works.
- Q:The child for LED the desk lamp that shield an eye myopia?
- Now there are some LED desk lamp which color temperature, due to the color temperature of LED light source is designed is fixed, so this kind of desk lamp USES is two different colors of light ratio of different brightness, change the function of light color, in order to achieve this kind of table lamp table lamp accurate sense should be the color that move light, desk lamp, not including color temperature also because of its light mixing two kinds of color, make the light clutter is not pure, can also cause some damage to the eyes
- Q:The LED lamp how to realize the function of adjustable brightness and color temperature?
- Simple dimming can be concatenated in the LED lamp bead loop resistance, change the current, can adjust the brightness, better with adjustable brightness of PWM pulse width adjustment, circuit is more complex. Color temperature seems to be no commonly, by LED lamp bead characteristics (fixed) materials and manufacturing has decided, unable to adjust.
- Q:Are LED lights compared to dc lights?
- Basically agree with net friend in front of the answer. The desk lamp of ordinary incandescent light bulbs with energy-saving lamps, bulbs and tubes in the current is an alternating current. Incandescent lamp current is ac mains, 50 hz, on and off the 100 times per second. Filament is high temperature heating, heat capacity to a certain extent, to cool and hot, stroboscopic was not obvious, but low light efficiency, energy saving. Energy-saving lamps, is the mains ac rectifier dc, again for the high frequency inverter (several thousand Hz) communication, energy saving, stroboscopic is not obvious, not like a normal fluorescent lamp. LED desk lamp, the energy conservation, but see, on the market at present basically is a built-in battery, use mains charging can't use the lamp, can light up from the mains before, often charging more than 6 hours, often should charge, so if used in a short time is can, such as to use for light continuously over a long period of time, is not convenient. LED flashlight, with short time, it is very good. If there is no battery, do not need to charge, it is more convenient. Above for your reference.
- Q:Pupils to do homework with good desk lamp is yellow light or white light is good
- Do your homework with white light lamp, room lamp with yellow light, this is the most close to natural light, best to protect the child's eyes
- Q:Children lamp good choice led lamp is better
- Use LED lamp is better. Save electricity, no flash, the light is downy. General energy-saving lamps such as uv radiation, and there will be a stroboscopic.. LED there is no such as uv radiation, there is no stroboscopic, longer life, count was more stable, and quick response.
