- Q: Light flashing, if is to use the adapter, it is possible that the adapter, try out in later.
- This seems not, but can be modified, specific how to operate, can go to the shenzhen LED lighting look at technical articles on net
- Q: Philips lamp with good light bulb or led
- LED bulbs than traditional incandescent lamp energy saving more than 80%, but the LED light source the light biological safety has not been very clear answer, see how do you choose
- 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
- Q: LED lamp stroboscopic serious, can you tell me the reason?
- Use digital camera LED lights have similar moire interference, should be a digital camera sensor scanning frequency and multiple leds blinking frequency with a certain relationship, lead to no photosensitive sensor some particular locations and appear black stripes. According to the phenomenon that the LED lamp is resistance capacity drive is premature. In general, if the LED lights use resistance capacity device driver, then stroboscopic frequency twice of the ac power frequency, i.e., using flash frequency 50 hz alternating current while the frequency is 100 hz, with 60 hz ac for 120 hz - under the frequency, the human eye or is there a way to identify: the five fingers outstretched rapidly oscillating in the lamplight, if can see "a lot of fingers in the middle of the swing range (shadow), you can judge the LED use the low frequency pulse power supply driver. If the LED is used inverter type constant current power source, then stroboscopic frequency up to 40 ~ 200 KHZ, wiggle the fingers in this light, the human eye of persistence of vision has been unable to form such as "image of guanyin", so it can be the difference between the judgment
- Q: What if the led lamp doesn't shine
- LED the working voltage is usually about 3 v, the circuit generally take three or six string a string, each string of working voltage is 12 v or 24 v, unwrapped desk lamp, look at the inside of the circuit can be known. If is the transformer working have to be replaced,
- Q: 22 what is the power of the led lamp charging desk lamp v
- Desk lamp is generally have a transformer, the home into a 12 v voltage of 220 v.I hope you can help me
- Q: Baby what kind of table lamp? The LED lamp can be eye really?
- Eye lamp to brightness is appropriate, not too bright also not enough brightness, stroboscope, basic can't see the kind of eye. LED is to save electricity, and then a slant blue, the other nothing.
- Q: LED lamp is broken, put it down, things do
- Make a 3 to 7 w drive, can directly to the utility. Of course you should guarantee the lamp bead not burn
- Q: With 10 v charger with 6 v rechargeable batteries used at the same time, that is used when mains mains, there is no mains automatic conversion electric battery. Three light bead is in series or parallel good? Add how much resistance? Step-down to to the charger? If I want the dimmer, should how to do, had better have circuit diagram
- 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: LED rechargeable lamps didn't work for too long, the result can't shine! How to do?
- Rechargeable batteries for a long time need not when, want to lie between period of time to charge. Battery not line, in rechargeable batteries, or to general battery don't forget to take out after using it
