Q:Why can't the voice switch control the time of the LED bulb?

Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds

Q:What are the driving IC used in LED bulb?

M8900 can replace BP3309, SY5810 SY5840 MT7930, ME 8316, without modifying the circuit used directly.M8900Is an original side feedback, with single stage active PFC high precision LED constant current control chip, M8900 integrated single level active PFC line, can achieve higher power factor and very low total harmonic distortion, chip canThe quasi resonant mode is achieved, thereby achieving higher efficiency and reducing switching losses. M8900 features multiple protection functions to ensure system reliability, including LED open circuit protection, chip overvoltage protection, and UVLO deficiencyVoltage protection, LED short circuit protection, cycle by cycle current limiting, etc..

Q:LED can the bulb be used in the bathroom?

Yes, the bulb may is waterproof and dustproof with protection

Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?

Cannot connect directly. LED bulb is usually a series of LED series, and then parallel, generally about 12V. Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.

Q:Seeking the production process of LED bulb... Thanks

10 points, Baidu wants to be a LED engineer. LZ is a real budget man

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?

One point price must be a sub goods, this is wrong.Plastic cheap because the cost is relatively low, can not talk about grades, plastic LED mainly for the application oriented,

Q:Are there any differences between negative ion bulb and LED bulb?

The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.

Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?

With the temperature of the heat sink to judge a lamp is not easy, the domestic aluminum radiator are generally more, for T8T5 will have to see the size of the whole lamp power, the simplest is to look at the weight, the relative materials generally heavier will be better.

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:What advantages does LED bulb replace energy saving lamp?

The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond
