Abstract

An LED light tube comprising: a light strip (1), a transparent cover (2) covering the exterior of the light strip (1), and several LED light sources (3) mounted on the light strip (1). The LED light sources (3) comprise: an LED chip (31) electrically connected to the light strip (1) and a transparent adhesive layer (32) covering a light-emitting side of the LED chip (31). The outer surface (321) on the transparent adhesive layer (32) opposite the LED chip (31) is a coarse surface. The coarse outer surface (321) of the transparent adhesive layer (32) scatters a light emitted by the LED chip (31). The light emitted by the point light source is scattered to produce a light providing a planar light source effect, thus preventing the human body from experiencing dizziness caused by a light in the form of a point light source, and ensuring comfort.
