Q:How do I get the four joints of the LED fluorescent tube
The LED fluorescent tube In fact, it is the connection column of the ordinary daylight lamp, the four connecting bars, each of which is 220V The LED fluorescent tube, which is connected to the AC DC transform at 220V, gives the internal LED power supply According to the internal implementation of the LED tube (whether the two ends are in parallel) At least two terminals at one end, which can be lit up by 220V, may be connected in parallel to this end, or an empty terminal
Q:How much is the ballast of the fluorescent tube coming out
IME's "flash" is pretty good. They've been working with them all the time, and the quality of the product is assured. 3W's LED skylights are only 14, 5 yuan, and in baidu's search for flash, fans can find their website. Other lamps and lanterns also sell very cheap, have the day flower lamp, shoot lamp, sunshine tube, ball bubble lamp, soft lamp belt and so on
Q:The notice of LED daylight lamp tube
The service life of the LED fluorescent tube, LED fluorescent lamp power saving more than 80%, life expectancy of more than 10 times of ordinary lamp, is almost free maintenance, often there is no want to change the lamp, ballast, the problem of electric fluorescent starter, about half a year down can switch back to the cost of cost savings. Green environmental protection of semiconductor lighting, the light is downy, spectrum pure, is good for eyesight protection of workers and healthy body, the 6000 k cold light source, give a person the feeling of cool and refreshing on the vision, help to concentrate, improve efficiency.
Q:The problem of LED lamp compatible ballast
Online are the so-called compatible led ballast, inside it is a constant current for high power led drive power supply, in order to adapt to a variety of different types of leds, it also has different output current varieties, also wants when buying according to the current to select the same current in the led lamp ballast compatible led, it with the ordinary led special-purpose ballast (is actually led a dedicated switch type constant current drive) is the difference on the power (which is the same kind of led do various tubes are common) is large, the range of output current of 300 ma compatible ballast, for example, it can automatically adapt to the current 300 ma from 9 w - any power between 25 w led bulb, but also has the smallest biggest range, the only requirement is that current to be the same.
Q:The difference between an LED tube and a daylight lamp
Traditional fluorescent lamps generally cannot choose color temperature, and color. LED bulbs have a choice.
Q:I hope my answer will help you
First push the lamp tube at either end. So the lamp is coming down.
Q:What kind of lamp tube is the 2G11 lamp of LED fluorescent lamp
It's a lamp holder, which is different from T8 T10. The spacing of the pins is different. Look at figure 2G11. If you don't understand, you can add me Q9, 5, 3, 4, 7, 2, 5, 3, 2
Q:Can a fluorescent tube be used in series?
How much voltage do you need to get through the two 20-watts series, and can a 40-watt ballast provide that high voltage? I don't think so.
Q:What is the difference between the daylight lamp tube used in fishing steel and the normal lighting tube
Ordinary bulbs are fluorescent lights, which are not the same as leds. The fluorescent lamp is the electric power of the ballast machine that produces the high pressure instantly, excited the two feet of the inside of the lamp tube to discharge, then stimulates the phosphor powder to shine. This process produces high heat. LED luminescence is an electron transfer within a semiconductor that produces light that does not produce heat. That's why leds are called cold light sources.
Q:Do the fluorescent tubes save electricity for 10 minutes, or do they save electricity in a split second?
Although the data is missing, the electric current of the opening is larger and the power consumption is no more than 10 minutes
