Backlight module, conductive module of lamp tube, and their manufacturing method

The invention relates to a lamp conductive module, a backlight module with said conductive module and a method for producing said lamp conductive module. The inventive lamp conductive module comprises several first fixing supports, several conductive bands and at least one tension adjuster. Wherein, each first fixing support comprises a first surface which has several first grooves; each conductive band is arranged on the first surface and over the first grooves; each conductive band has two opposite end parts; and the tension adjuster is connected to the end parts of each conductive band.
