  • Tubular lighting apparatus with protection portion
    Patent number: 11009223
    Abstract: AN LED tube apparatus has a tube body with two opposite ends fixed to a first cap and a second cap. AN LED module is placed in the tube body. The LED module has a driver circuit containing an electronic ballast that generates high frequency electric current. The first cap has two first metal pins to be inserted in a first socket end of a light tube bracket. The first metal pin clutches an end of a leading wire. The leading wire has a protective portion breaking off when the first metal pin is applied with a predetermined range of heat generated by the high frequency electric current when the LED tube apparatus is not operated properly.
