Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: LED is the most important heat, light will not be so serious, the thermal conductivity is relatively high Aluminum Alloy, so LED manufacturers usually choose to use aluminum shell

Q: Where can LED bulb be used?: LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection.

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: Can the bulb's true life reach 30000~50000 by LED?: According to the current LED manufacturing technology, LED bulb has a lifetime of up to 30000 hours.

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: What is the AC voltage of the LED bulb?: The AC voltage of LED bulb is usually 220V, and the power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.The biggest market for LED bulb lighting is the civilian market, and the LED bulb is a new green light source to replace the traditional incandescent bulb. LED lamp has the advantages of energy saving, environmental protection, long service life, no stroboscopic, green and so on.

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: Led what's the flash of the bulb?: There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright.

Q: Want to find common features, unified purchase accessories repair!: The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
