- Q: LED thread specifications for bulb bulbs?
- Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.
- Q: Where can LED bulb be used?
- Led bulb is now commonly used in civil products, is the most is a spherical bulb
- 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: Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
- The first is Aluminum Alloy better heat dissipation, aluminum is relatively high, and made products, together with the positive effect is not the same, in addition, the wick and the circuit there will be differences, this will also affect the application of life and feelings.
- Q: Can the bulb's true life reach 30000~50000 by LED?
- The white LED lighting bulb basically is to use GaN based blue LED excitation light yellow fluorescent powder to realize white light, which is a two yuan color white, there are three kinds of RGB LED chip mixed light, but the high cost of LED, the general industrial production less
- 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: Are there any differences between negative ion bulb and LED bulb?
- LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
- Q: Is it possible to manually weld LED bulb bulbs?
- You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
- Q: Why can't the voice switch control the time of the LED bulb?
- Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
- 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
