- Q: LED lights it is transistor luminescence is not pure resistance filament bulbs, when dimming voltage changing, the frequency is changing so affect rectifier, sudden high voltage will burn out the LED.
- Who recommended the first floor of the answer, he was mistaken about the basic knowledge, also recommended? Three kinds of lamp, incandescent lamp the best color, 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.
- Q: Are LED lights compared to dc lights?
- Leds are generally constant current drive, also is the dc driving lights, as long as give the LED current to the rated current of the LED itself is not stroboscopic, unless there is something wrong with the power supply itself.
- Q: Why do some led desk lamp is white light, have a plenty of take a bit of blue?
- With a little bit of blue is light; LED lighting is generally warm white, is white, cold white three color; Warm white, the color of light yellow, let the human look at warmer, solid said warm white. Warm white LED lamp light like a tungsten filament bulbs before that kind of color, can be used for household lighting. Is white, the color of the light color to white light gradually, but the color temperature of light color eye look more natural, reason is called white, also called natural white. Is the color of white light like a rod daily to the light, is also used for household lighting.
- 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.
- Q: A LED light source is, but is not a plug-in, the power supply is a similar phone charger that this kind of desk lamp belongs to direct current (dc) or an alternating current, will it be a stroboscopic?
- A stroboscopic, stroboscopic degree depends on the quality of power supply. In theory, the desk lamp belongs to the direct current (dc), but after ac DianZhuan into dc, so after rectifying filtering, is not entirely direct current (dc), a part of ac harmonic superposition. Only in the battery as a power source is the real dc no stroboscopic LED light source, suggest using rechargeable LED lights.
- Q: There are several major disadvantages of LED lamps
- A, monochromatic light source, chromatography is too narrow, can have influence on the eyes of the optic nerve, fatigue Second, the price is more expensive, compared to other light sources, prices are high.
- 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: Pupils to do homework with good desk lamp is yellow light or white light is good
- Desk lamp is good, eyes comfortable is the most important. Actually now the LED for the eyes, is really bright flashing eyes, but in the long run really uncomfortable. Old lamp luminous tube flashing LED lights, dazzling, entanglements...
- Q: Study desk lamp high-power led is more appropriate
- Hello, choose close reading and writing desk lamp must choose protect eyesight! LED lamp cannot be used as close to read and write operations, because leds emit short-wave high-energy light - blue light, can be directly through the cornea and lens, can direct the macular area, cause burns to the retina. Whether a desk lamp eye health mainly judging from three aspects, one is no stroboscopic; The second is the light right; Three is no uv radiation.
- Q: LED small desk lamp, found that the charging indicator light is not bright, or bad?
- You put the electric light, and then filling, can see light, not just can not charge the electricity, if can light is the light is broken, and there's some light charging is not bright, full of bright, look ok
