- Q: The LED lamp electrostatic test pass the corrective actions
- I think you the electrostatic distance from control circuit to leds this recent, one is in the line where the sliver, the second is the detection circuit chip input port less resistance and capacitance, let the minimum electrostatic effect on circuit,
- 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: Long amount of brand of LED desk lamp capacitor charging Fried v100uf 50
- Resistance is replaced This desk lamp should be used on the 24 v power supply
- 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: How to choose the night reading reading lamp
- The desk lamp that shield an eye, the type of LED desk lamp that shield an eye of warm color, it is best to solar energy, no glare, no flicker, long time reading will not cause eye fatigue. Solar panels will absorb sunlight during the day to recharge, desk lamp power.
- Q: Low voltage LED desk lamp belongs to the scope of 3 c certification
- What is the low voltage LED lamps, whether with a charging device. If you are charging device, or take the adapter to connect power part is need to do
- Q: Long card LED charging small desk lamp
- Use desk lamp of 5 hours a day, a month how to use electricity. This kind of LED desk lamp is very energy. If you are only used for lighting, can answer 0 degrees, almost no electricity, electricity meters are invisible. If you want to study how much degree, the za to calculate. 12 lamp holder is 12 leds, each press 3 v, 25 ma calculation, power P = 12 * 3 * 25 = 900 mw = 0.9 W, before considering other loss, even if the power is 1 W. 1000 watts of electrical appliances use 1 hour to 1 KWH 1 KWH, the desk lamp of 1 watt 1 months use 150 hours is 0.15 KWH. So for the average person can answer 0 degrees. Do you have any questions? Can you give me a message!
- Q: A led desk lamp always zi zi ring is how to return a responsibility?
- Inside thrum have poor contact, look at the best, don't have accidents
- Q: So only the halogen lamp, but is low voltage halogen lamp, need a rectifier, and halogen lamp itself temperature is high, pay attention to the heat dissipation, color rendering index selected 90-100, color WenXuan 2700 k, the best for you.
- Line loss, it is good to connect.Of course, can also according to component model and buy a change.
- Q: The voltage of the LED lamp is about how much
- If you buy a product of lamps and lanterns, it should indicate the rated voltage. If it is homemade, you can choose according to the input voltage connection. You three series, 5 groups and then together, you can pick up in 10 v
