- Q:What are the driving IC used in LED bulb?
- MT7930, LM3445MM do bulb bulb, the effect is also ok.
- 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:LED thread specifications for bulb bulbs?
- Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.
- Q:Is it possible to manually weld LED bulb bulbs?
- This is what you do very mature products, the most simple aging, is like this
- Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
- General household enough, if in 10 square meters of housing, installation of more than 10W LED lights, brightness is too good, if not the study, it is best not to.
- Q:LED how does the bulb return electricity?
- A 0 ohm resistor with a large point on the negative electrode
- Q:What advantages does LED bulb replace energy saving lamp?
- LED lamp structure is strong, green environmental protection, not easy to destroy, long life (generally 5 years is not a problem), this is energy-saving lamps can not be compared
- 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:What are the requirements of the LED series inspection specification for bulb bulbs?
- The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.
- 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
