Q:How to identify Ic constant current LED bulb?: Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.

Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?: It's possible to assemble your own bulb. The power used in the bulb is too large. It causes the gold wire to burn

Q:What's the reason why LED bulb gets a lot of heat?: If the radiator has a large radiating area, the temperature is low

Q:How to choose the bulb power?: LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. Have the advantage of all LED lamps and lanterns:1, energy saving, environmental protection;2, long service life;3 、 no strobe, green.

Q:What's the difference between a glass cap for a bulb and a PC hood?: Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.

Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.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.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

Q:What's the cause of the noise during the aging of LED bulb bulbs?: The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.

Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!: Can reach 90% of the light, can not see the inside of the lamp

Q:What does "A19" mean in LED A19 bulb?: A represents the bubble type, A hemisphere bubble 19, and the back figure indicates the bubble size (mm in diameter)

Q:Can the bulb's true life reach 30000~50000 by LED?: The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
