Q: LED thread specifications for bulb bulbs?: Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount

Q: LED how does the bulb return electricity?: What is reflow? Never heard of it. I am a lighting technician

Q: What's the reason for the LED bulb strobe?: In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.

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: 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: Are there any differences between negative ion bulb and LED bulb?: Negative ions should belong to traditional lighting technology, LED is the latest lighting technology

Q: LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: 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 achieve normal brightness, or it may damage the USB interface. It's better to use the USB charger interface. DIY needs circuit knowledge.

Q: Detailed description of LED bulb lamp: A bulb can be said to be the highest cost of the driver, not the driver, light is not bright. And for the quality of a ball bubble

Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: LED bulb lamp, are driven by a power of the ordinary small beads, driving is very simple only rectification, filtering, limiting the number of components is another large power SMD beads, this drive is more troublesome, SMT SMD components, and double plate, both have the element.
