Abstract

An LED tube lamp comprises a lamp tube, which includes a light transmissive portion, a reinforcing portion and an end cap; and an LED light assembly, which includes an LED light source and an LED light strip. The light transmissive portion is fixedly connected to the reinforcing portion. The reinforcing portion includes a plurality of bracing structures at endpoints. The bracing structure includes a combination of vertical ribs and horizontal ribs. The LED light strip abuts against the bracing structure, which guides the LED light assembly in place. The LED light assembly finds upright support by the reinforcing portion. The LED light source is thermally and electrically connected to the LED light strip. The end cap is attached to an end of the lamp tube. R15 is a ratio of an overall length of the reinforcing portion that shows itself on a circumference of a cross section of the lamp tube to an overall length of the light transmissive portion that shows itself on the circumference of the cross section of the lamp tube. R15 is a constant regardless of where the cross section finds itself on a longitudinal axis of the lamp tube. R15 is from 0.02 to 1.65.
