Abstract
An LED tube lamp having: 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 platform and a bracing structure. The bracing structure is fixedly connected to the platform and holds the platform 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. An outer surface of the lamp tube reveals a combination of metallic outer surface and nonmetallic outer surface.
