Abstract

The invention discloses an LED lamp tube which comprises a heat dissipation shell, a lampshade, end covers positioned at two ends of the heat dissipation shell and the lampshade, a circuit board fixedly connected with the heat dissipation shell and LED chips positioned on the circuit board, wherein the heat dissipation shell has a curved surface with an arc-shaped cross section and is fixedly connected with the circuit board through the curved surface. Therefore, when the circuit board and the curved surface are combined, the LED chips positioned at different positions on the circuit board have different normal directions, and further, the view angle of the whole LED lamp tube is enlarged.

Description

technical field [0001] The present invention relates to the technical field of LED (Light Emitting Diode) lamps, and more specifically relates to an LED lamp tube with a relatively large irradiation angle. Background technique [0002] In recent years, LED lamps have attracted much attention because of their energy saving, more environmentally friendly, high efficiency, small size, and longer life. LED lamps are replacing traditional incandescent lamps and fluorescent tubes as mainstream lighting tools. At the same time, with the development of clean energy efficiency technology and the increasing awareness of people's environmental protection, more and more homes and institutions will adopt LED lamps for lighting. Under this trend, it is particularly important to ensure the absolute safety of LED lamps and prevent potential safety problems such as electric shock. [0003] Please refer to figure 1 , a LED lamp tube 100 in the prior art includes a heat dissipation shell 110...
