- Q: What are the types of LED bulb?
- According to the interface, the LED bulb has GU10, E14, E27, E40 and so on.
- Q: LED bulb w can replace 40W incandescent lamp
- The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
- Q: LED can the bulb be used in the bathroom?
- Yes, the bulb may is waterproof and dustproof with protection
- Q: What does the LED bulb patch mean?
- According to different applications, different size, cooling scheme and luminous effect of.LED packaging forms. At present, according to the classification of LED package are mainly Lamp-LED, TOP-LED, Side-LED, SMD-LED, High-Power-LED, Flip Chip-LED Lamp-LED (vertical LED) emerged in the early Lamp-LED is in line LED, it adopts the form of sealing packaging. The potting process is the first injection of liquid epoxy resin in LED molding cavity, and then insert the pressure LED bracket welding, in the oven make epoxy resin after curing, the LED from the cavity from the molding. Due to the relatively simple fabrication process, low cost, have a higher market share. (SMD-LED surface mount LED) patch LED is pasted on the surface of a wiring board, suitable for SMT processing, can be reflow, a good solution to the brightness, perspective, smoothness, consistency, reliability and other issues, the The lighter PCB plate and a reflecting layer material, improved to remove the carbon steel pin dip LED heavier, the display of epoxy resin less reflective layer needs to fill, to reduce the size, reduce the weight. In this way, the surface mount LED can easily reduce the weight of the final product in half, make the application more perfect.
- Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- The meter usually doesn't turn because the current is too small to drive the meter (Mechanical), of course, the electronic meter also depends on the sensitivity. I don't think so. At least I used to do LED (light power about 0.5W it) is equivalent to 3W incandescent lamp brightness around. The meter does not rotate when it is shining normally.
- Q: Will the power of the LED bulb grow longer and longer? Why?
- Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.
- Q: Choose which light bulb LED bulb is the healthiest
- The two said warm light, power, color temperature and so on have little to do with health
- Q: Is there any flicker in the LED bulb?
- Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there. Questions raised by the questioner can show that you are observant.
- Q: Want to find common features, unified purchase accessories repair!
- The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
- Q: What does "A19" mean in LED A19 bulb?
- A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
