Abstract

An improved LED lamp tube structure includes a shell (6) and a PC cover (7). The shell (6) and a PC cover (7) can be fastened to each other to form a cavity (61). A circuit board (1) is disposed in the cavity (61). A plurality of LEDs (5) is mounted on the circuit board (1) and arranged in the longitudinal direction of the circuit board (1). Each of LEDs (5) has a light-emission angle. The PC cover (7) has an arc angle equal to the light-emission angle. Each of the LEDs (5) extends in a direction perpendicular to the longitudinal direction of the circuit board (1).

Description

technical field

[0001] The invention relates to the field of LED fluorescent lamps, and more specifically relates to an improved structure of an LED lamp tube capable of solving the black areas on both sides of the LED fluorescent lamp. Background technique

[0002] With the continuous development of domestic LED technology, many manufacturers are currently considering taking advantage of the talent advantage of low domestic labor force to sell their LED fluorescent lamps to Europe and other overseas countries. However, if they want to sell their products to Europe, they must make their products Meet European product certification.

[0003] For example, there is a requirement in the European certification that the distance between the LED lamp in the LED fluorescent lamp and the outer edge of the aluminum substrate is at least 5mm; due to the use of oblique arrangement or a word in the prior art (such as 3014, the length direction of 30 is parallel to the length direction of...
