Q:LED can the bulb be used in the bathroom?
Yes, the bulb may is waterproof and dustproof with protection
Q:LED bulb bulbs, do you need 3C certification now?
Light source class is impossible to do, only lamps and lanterns class can do. For example, flat lamp, ceiling lamp and so on...However, CQC voluntary certification can be done.
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: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:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
The standard is the body temperature of the LED lamp. With a multimeter probe is placed in the LED lamp bulb angle can be measured temperature. Generally -20~80 degrees centigrade
Q:LED how does the bulb return electricity?
What is reflow? Never heard of it. I am a lighting technician
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.
Q:What's the difference between a glass cap for a bulb and a PC hood?
Surface hardnessPC biggest weakness is surface hardness, PC although resistance to impact, smashing not broken, but after all is plastic, surface hardness value is not high, easy to scratch, easy to scratch.While glass is easy to break, not shock, but the surface hardness is high, it is not easy to scratch the surface!Other weather resistant, temperature resistant supplementsPC cover, in processing, plus UV agent
Q:Where can LED bulb be used?
LED bulb is generally civilian, living room, study room, kitchen, bathroom and so on
Q:LED bulb w can replace 40W incandescent lamp
D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.
