Three methods of wiring for LED tube light
LED fluorescent tube light wiring can be divided into three types, they are the ends into the line, single-ended line and staggered into the line.
Ballasts and starter in Traditional fluorescent lamps are not needed in LED fluorescent tube, and magnetic ballasts will consume some power, measured without removing the ballast, 18WLED fluorescent tube input power can be up to 20.5W, so waste 2.5W power.
Greenough Led lamp manufacturers recommendations: 1. must remove the starter. 2. It also be ok if it is really inconvenient to remove magnetic ballasts.
Among the three wiring, led fluorescent tube all can work properly with or without magnetic ballast.
Both ends into the line is an early and common of connection, because of its easy wiring, simple ageing etc. So far this method is still used by a lot of LED lamp manufacturers. The two needles of lamp base are shorted together, and then connected to the internal constant current power supply. Only need to remove the traditional starter with such wiring method, able to work properly.
Wiring single-ended line: The one end is not wiring, the other end of the lead to two needles were on constant current drive power. There is no connection between the two lamp caps. The greatest advantage of this is safe, if one end connected to the AC power led lamp, then the other end will never be charged. Replace traditional fluorescent when you need to remove the original starter, replaced starter fuse ", installed on the lamp on it.
Staggered into the line is a relatively new way, this wiring have some requires on the internal drive for LED lamps, you need to have a two-way exchange into the line side. The greatest advantage of this wiring is the light all is able to work properly whether with the starters or not. Just need to replace the lamp when replacement is needed, the operation is very convenient. Compatible Philips, Osram, Hitachi, Panasonic, Toshiba and other electronic ballasts all used this connection.
