Abstract
The invention involves an LED tube lamp, which comprises a lamp tube, which includes a light transmissive portion, a reinforcing portion and an end cap. The LED tube lamp further includes 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 LED light strip abuts against the reinforcing portion, which holds the LED light assembly in place. The LED light source is thermally and electrically connected to the LED light strip, which is in turn thermally connected to the reinforcing portion. The end cap is attached to an end of the lamp tube. A ratio of a cross-sectional area of the reinforcing portion to a cross-sectional area of the lamp tube is from 1:3 to 1:30.
