- 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: Amount for the LED - 666 desk lamp can use charging time
- Strictly speaking, it is best not to use when charging. Because: 1. Easy to get an electric shock. 1. Affect the service life of the product. Charging desk lamp is with leds (Light EmittingDiode) the desk lamp of the light-emitting diode as Light source, with lithium battery and USB charging function, the LED is a solid-state semiconductor devices, it can be directly put DianZhuan into Light. USB charging desk lamp is a desktop or laptop computer USB mini rechargeable lamps. Is through the computer connected to the computer USB interface, downy light, most of the charging desk lamp can adjust the brightness of the light, two control as you need to change, is very convenient. The USB port on the computer (that is, everyone is used to insert USB interface) for external voltage of 5 v power supply for the equipment, the current 500 ma, USB charging small desk lamp of desk lamp is with USB interface to provide power supply, lamp take up the space is not too much, and very save electricity, suitable for office workers or students. maintenance Household appliances maintenance led rechargeable lamps? Many users haven't noticed that some users will be LED rechargeable lamp is like electricity used up until then recharging it when you are going to use it. LED rechargeable lamp light life is compared commonly, if it is not because the excess voltage or short circuit, usually don't burn out.
- Q: Led desk lamp and common desk lamp which is good
- If the wavelength change, stimulate phosphor ability to drop, luminous efficiency will be lower. Manufacturers in order to pursue the brightness, usually to strengthen the blue LED light intensity, the eye if the long run, such a source to avoid eyes blue light damage. In addition, it is, the longer the LED light, the faster the phosphor decay of light source, the result will lead to the human eye contact blue wavelengths of light is more and more intense, so as to cause harm to the human eye
- Q: How to maintenance of led desk lamp filled in no electricity
- It seems is the switching power supply, circuit board above and have a look. You understand the welding and the multimeter test? If you don't send repair shop
- Q: Use LED lamp plant useful? Useful for which plants, which plants useless?
- LED lights line downy, spectrum pure, no ultraviolet light. 1, energy saving. 2, long service life. 3, good applicability, due to the small size of the single star LED, can be made into any shape. 4, short response time, is the ns (ns) level of response time, while the common lamps and lanterns is ms (ms) level of response time. 5, environmental protection, no harmful metals, waste recycling easily
- Q: The problem with LED charging lamps?
- You can see on taobao can I recharge my core desk lamp, the great ahhh
- Q: Card lamp, LED desk lamp can take a plane
- Look at the battery storage is not too large should be ok
- Q: Desk lamp battery charging why not directly connected light emitting leds, but to a diode, the diode have what effect
- Ordinary pressure drop with the silicon diode rectifier is about 0.7 V, the series circuit is higher after the voltage sharing the 0.7 V, so your LED can work properly. Can be a little bit, the pressure drop on the diode wasted energy is 0.7/3.3 = 21, see, there are twenty-one percent of the energy contribute nothing.
- Q: ：Rechargeable led bulbs on the desk lamp is a few volts?
- Galvanic battery 4.47 V, the brightness of the light brighter than 4.2 V now, are you? You can try the 5 v charger, should be able to increase brightness. Brightness increased, however, is to rely on the voltage, made for light-emitting tube, will reduce the service life. This is the price.
- Q: LED lamp wattage? How much is the smallest biggest respectively?
- The main characteristic is to save electricity, under the condition of the same brightness, than the ordinary energy-saving lamps save electricity more than half
