Q:What does an led light ballast out of out mean
Hello, you say the LED light ballast is actually the driver power of the LED lamp, the input input input and the output terminal output, the input is connected to the city power, the output output is connected to the lamp tube
Q:How to judge the quality of electronic ballast
According to the international standard, light 1 second at 20%, more than 4 seconds 80% brightness is good ballast, while 80% of that moment of brightness or four seconds can not meet the standards of the brightness of the ballast quality is poorer.
Q:How should the power meter be connected and illustrated
You can't use a multimeter to test with a special instrument.
Q:Do you use a 50Hz ballast for the lamp of 220v 60Hz
It may not be possible, depending on the structure of the ballast itself. A, if the lamps and lanterns is used within the ballast is the inductive limit flow (e.g., low cost design of high pressure mercury lamp), suitable for the occasion of 60 hz, the inductance may be applicable to the 50 hz occasions about 20%, so the current rating of 20%, probably more than design flow effect and may make core magnetic saturation, led to the decrease of the inductance further... The resulting flow of light is damaged;
Q:How does the ballast work
When the fluorescent lamp after access circuit, electric fluorescent starter began to glow discharge between two electrodes, the bimetallic strip heat expansion and contact with the static contact extremely, so the power supply, ballast, filament and electric fluorescent starter constitute a closed loop, current filament preheating, 1-3 seconds when the heating time, electric fluorescent starter of glow discharge between two electrodes, then the bimetallic strip cooling and static contact is extremely disconnected, when two electrodes disconnect instantly, the current in the circuit suddenly disappeared, so ballast produces a high voltage pulse, and it has to do with power superposition, on both ends of the tube and, make the inert gas ionization inside the tube caused by arc discharge, in the process of normal light, ballast self-induction is still stable circuit in current role.
Q:Is the electromagnetic ballast a inductive ballast?
In the case of fluorescent lamp, there is no electromagnetic ballast, only the inductive ballast and electronic ballast.
Q:The function principle of fluorescent lamp ballast
After power on, 220 v alternating current through the ballast, under the effect of the mutual inductance ballast produces about 600 v high voltage, add on the tubes, no reflect the tubes, but in parallel in the other side of the tube electric fluorescent starter, due to the high voltage of 600 v is obtained by filament, and add on both ends of the electric fluorescent starter, due to the internal electric fluorescent starter neon bulb can't bear the high pressure of 600 v, breakdown in the neon bulb neon, and a red light, and emit heat, the thermal contact neon bulb,
Q:Can ballast be replaced with the usual daylight tube ballast?
You can use the 15W uv lamp to buy 18W ballast and the 15W ballast is not seen
Q:Can a 22w led ballast be used for a 12w lamp
You can't change the structure, but of course that's what I think.You can't change the power.,
Q:What is a ballast?What the ballast is doing
High 2 physics has, be used to limit the current too big, can make the lamp tube has stable current in short time! There are two types: inductance and high frequency. The inductance is too large and bulky, so it is generally used in high frequency
We are a well-known enterprise specializing in the production and sales of high-grade Ballast. Since the establishment of our company, we have been devoted to setting up a good reputation in the world.
