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:Secret LED bulb bubble price difference why so big?
Component material. Whenever cheap prices are shoddy, without exception
Q:LED thread specifications for bulb bulbs?
Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;
Q:Can the bulb's true life reach 30000~50000 by LED?
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
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?
The internal drive of a cheap LED bulb is generally a resistance drop, and voltage fluctuations can occur in a flash. So all 100 of you are a flash.
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
100lM/W LED bulb, 4-5W can be replaced. If it is white 4W can be, if it is warm white (yellow light), preferably 5W, mainly human eye feeling, white light than Huang Guangliang.4-5W LED bulb, equivalent to 12-15W energy-saving lamps
Q:Want to find common features, unified purchase accessories repair!
The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
Q:What does "A19" mean in LED A19 bulb?
A represents the bubble type, A hemisphere bubble 19, and the back figure indicates the bubble size (mm in diameter)
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
Because LED's normal luminous current is 20MA, and LED has a weak current, it can emit light. According to this source. Maybe your line is just on the zero line. This will lead to a small leakage current flows through the LED lamp.Try offline.
