Q:Is there any flicker in the LED bulb?

That should be a combination of small power and multiple LED lights! The main reason is the strobe power problem, to tell the truth, I do not set the LED power supply, improvement in the well to be unable to give you much help, our production of LED products, the procurement of materials and parts suppliers will request strobe or in the power supply design problem, if you want to buy LED products, especially is the bulb, I suggest you buy a large power assembly (i.e., the shell is Aluminum Alloy)!

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

Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.

Q:Where can LED bulb be used?

LED bulb is generally civilian, living room, study room, kitchen, bathroom and so on

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?

Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)

Q:What's the reason for the LED bulb strobe?

Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q:LED thread specifications for bulb bulbs?

Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!

Q:How does the LED bulb go with the power?

Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V

Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!

Delays generally do not exceed 1S. After rectification, the capacitor is charged to the IC VCC terminal through the starting resistance. When the starting voltage of the IC is reached, the output switch pulse signal of IC is LED, and the luminous work is realized.. That is to say, the greater the capacitance, the longer the delay.

Q:Choose which light bulb LED bulb is the healthiest

Choose LED lights, first, no strobe, strobe damage to the eyes, second color index to be high, true and clear. For the quality, choose to heat better, high power factor, so that the relative power of the lamp, power saving, durable

Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!

If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
