FAQ

In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
LED working environment temperature refers to the temperature of the air in the LED bulb, not the temperature of the aluminum substrate. The temperature of the aluminum substrate will rise as the LED lights up, and rise to a certain extent, which will involve the highest environmental temperature.
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.
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.
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.
How does the LED bulb go with the power?
Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V
LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
Delays generally do not exceed 1S. After rectification, the capacitor is charged to the IC VCC terminal through the starting resistance. When the starting voltage of the IC is reached, the output switch pulse signal of IC is LED, and the luminous work is realized.. That is to say, the greater the capacitance, the longer the delay.
Is it possible to manually weld LED bulb bulbs?
As long as the welding technology clearance is possible or OK
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.
