*The actual luminous output of an LED Bulb varies with the color temperature and cover type.Above data is for 6000-6500K,Milky cover

Q: What's the reason why LED bulb gets a lot of heat?: LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different

Q: Ordinary lamp LED bulb can?: Yes, just buy a high voltage LED light bulb. Contact me. I'll send it to you from the factory

Q: Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?: The LED price of aluminum alloy 3W is probably about 30.

Q: How to choose the bulb power?: If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.

Q: What are the types of LED bulb?: The LED bulb replacement use convenient, makes this type of products are widely accepted by users by the family, under the same illumination conditions choice to replace the traditional lighting.

Q: What's the reason for the LED bulb strobe?: 8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.

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 what does "A60" mean by bulb 60? And what does "MR16" mean?: MR is a reflector that is represented by a plurality of reflector groups, and 16 represents the maximum outer diameter of 1/8*16*25.4=50

Q: Why can't the voice switch control the time of the LED bulb?: The production lights can be controlled. Where do they go to consult?

Q: What brand of LED bulb is good in quality?: What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.
