US 2021/0199253 A1 · LED TUBE WITH BUILT-IN DRIVING POWER MODULE

Abstract

An LED tube with built-in driving power module is provided. Each of two ends of the LED tube has a conductive component electrically connected to mains supply. The conductive component at least includes a conductive pin assembly and a sleeve member for disposing the conductive pin assembly. The driving power module is formed by circuit boards, and the circuit boards are disposed in the sleeve member. Each of the circuit boards at least includes a functional operation unit, and the circuit boards are in series connection via one or more electrical connection members. The capacity space at both ends of the sleeve of LED tube is used to concentrate each circuit board in order to make full use of the capacity space. Meanwhile, the larger sleeve mold structure is avoided to cause the change of product appearance and increase the project development cost.
