Abstract
An LED tube lamp comprises a lamp tube, which includes a light transmissive portion; a fixing structure and an LED light assembly, which includes an LED light source and an LED light strip. The light transmissive portion is fixedly connected to a surface of the fixing structure and the LED light strip is fixedly connected to another surface of the fixing structure. The LED light assembly finds upright support by the fixing structure. The LED light source is thermally and electrically connected to the LED light strip. Two end caps are attached to two end of the lamp tube respectively. R3 is a ratio of an overall area of a metallic object on a cross section of the lamp tube to an overall area of a nonmetallic object on the cross section. R15 is a constant regardless of where the cross section finds itself on a longitudinal axis of the lamp tube. R3 is from 0.005 to 0.1.
