Q:What's the reason for the LED bulb strobe?
Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.
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 bulb PC, will the white cover affect the color temperature of the finished lamp?
The chip may damp, no air humidity warehouse management process; or the chip in the assembly process by foreign influence, the lampshade is removed, and then measured once in the color of the aluminum plate radiator
Q: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
The standard is the body temperature of the LED lamp. With a multimeter probe is placed in the LED lamp bulb angle can be measured temperature. Generally -20~80 degrees centigrade
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 thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
Q:What does "A19" mean in LED A19 bulb?
A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
Q:What are the driving IC used in LED bulb?
M8900 can replace BP3309, SY5810 SY5840 MT7930, ME 8316, without modifying the circuit used directly.M8900Is an original side feedback, with single stage active PFC high precision LED constant current control chip, M8900 integrated single level active PFC line, can achieve higher power factor and very low total harmonic distortion, chip canThe quasi resonant mode is achieved, thereby achieving higher efficiency and reducing switching losses. M8900 features multiple protection functions to ensure system reliability, including LED open circuit protection, chip overvoltage protection, and UVLO deficiencyVoltage protection, LED short circuit protection, cycle by cycle current limiting, etc..
Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.
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.
