- Q: What's the reason why LED bulb gets a lot of heat?
- If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long
- Q: How does the LED bulb go with the power?
- Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.
- Q: Led the bulb is flashing. What's wrong with it? How do you fix it?
- There is a drive power failure, and if you do not electronic repair ah, it is recommended to return directly to another driver, generally have 1 years warranty period
- Q: LED bulb w can replace 40W incandescent lamp
- I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.
- Q: How to identify Ic constant current LED bulb?
- Let me tell you what. If the bulb is not damaged, the regulator needs a regulator to lower its voltage and see if the bulb's brightness is dark. If it follows, it is not a constant current source, but a blocking capacitor. If the voltage is greatly reduced, the brightness change is not constant, that is, the constant current source bulb (because the constant current source lamp can change between 80V--260V, the voltage is normal, and the output is constant).
- Q: Is it possible to manually weld LED bulb bulbs?
- As long as the welding technology clearance is possible or OK
- 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: Detailed description of LED bulb lamp
- Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes
- 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.
- Q: Secret LED bulb bubble price difference why so big?
- Lamp beads。 I also do with Samsung bulb, bulb, lamp light cost more than others product price;
