Abstract

A matrix LED light tube gain structure suitable for replacing a fluorescent lamp includes an elongate metal base having a surface portion formed with screw holes for securing a matrix LED light strip with bolts, a cover having two lateral edges each protrudingly formed with a rail, two engagement blocks, and two end caps. The elongate metal base has two lateral edges each formed with a rail groove for engaging with a corresponding one of the rails on the cover. The elongate metal base further has two ends each engaged with a corresponding one of the engagement blocks and then combined with a corresponding one of the end caps.

Claims

1. A matrix LED light tube gain structure, comprising:

an elongate metal base having a surface portion formed with screw holes for securing a matrix LED light strip with bolts, wherein the elongate metal base has two lateral edges each formed with a rail groove;

a cover having two lateral edges each protrudingly formed with a rail for engaging with a corresponding one of the rail grooves formed on the two lateral edges of the elongate metal base;

two engagement blocks each formed with a through hole having a same shape as each of two ends of the elongate metal base for engaging with each said end of the elongate metal base; and

two end caps each having a cylindrical shape and provided with two conducting terminals;

wherein the matrix LED light tube gain structure is assembled by firstly securing the matrix LED light strip onto the surface portion of the elongate metal base with the bolts, inserting the rails on the two lateral edges of the cover into the rail grooves formed on the two lateral edges of the elongate metal base respectively, inserting the two ends of the elongate metal base into the through holes on the engagement blocks respectively, and finally combining the two ends of the elongate metal base with the two end caps respectively, thereby forming the matrix LED light tube gain structure.

2. The matrix LED light tube gain structure as claimed in claim 1, wherein the matrix LED light strip secured on the surface portion of the elongate metal base with the bolts comprises a plurality of such matrix LED light strips.

3. The matrix LED light tube gain structure as claimed in claim 1, wherein the matrix LED light strip secured on the surface portion of the elongate metal base with the bolts comprises only one such matrix LED light strip extended in size.
