Q:Secret LED bulb bubble price difference why so big?: Remember, cheap, no good goods, the market price of less than 15 yuan bulb said that their quality is not credible.

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:What brand of LED bulb is good in quality?: View brightness. Incandescent lamps usually only talk about wattage instead of lumens, but LED bulbs can count in watts, but wattage does not represent the number of lumens due to the continuous development of LED's luminous efficiency.

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:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: PDT flame retardant plastic, good heat dissipation, flame retardant effect, you see is not very good?

Q:LED what kinds of screw bulbs are there?: Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.

Q:Will the power of the LED bulb grow longer and longer? Why?: Voltage problems, as well as unstable factors.Long time no change, should

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!: Plastic bulb lamp, I have done it myself, this gadget specializes in low-end market, it is recommended not to use, used well, used for a long time, used poorly, minutes of effort have to hang.

Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind
