In order to solve the technical problems, the utility model adopts the following technical scheme:

An LED lamp tube convenient for heat dissipation comprises a heat dissipation shell, an LED light source assembly, an LED driving assembly, a light transmission cover and two end connecting pieces, wherein the LED driving assembly is connected with and drives the LED light source assembly to work, the LED light source assembly and the LED driving assembly are arranged on the heat dissipation shell, the end connecting pieces are arranged at two ends of the heat dissipation shell,

The heat dissipation shell is rectangular form, the heat dissipation shell includes the support body, the upper end of support body is fixed with the radiating fin that a plurality of intervals set up, the lower extreme of support body is provided with the hypoplastron, the sunk formation in hypoplastron middle part sinks the platform, a plurality of holes of stepping down have been seted up to the platform that sink, the both sides of hypoplastron are connected with the printing opacity cover.

Like this, at the during operation of LED light source subassembly, the heat that LED light source subassembly and LED drive assembly produced flows upwards, through the setting of hole of stepping down for the heat better passes the hole of stepping down and continues upwards gives off, and the radiating fin through the support top dispels the heat fast, will be close to the heat of LED light source subassembly and LED drive assembly and take away fast, improves the radiating effect.

Wherein, the radiating fin is provided with radiating holes.

The lower plate is fixedly provided with a lower radiating part at two sides, and a plurality of radiating grooves are formed in the lower radiating plate.

The light-transmitting cover is bent inwards to form a hook, and the hook can be in sliding fit and in hooking connection.

The main frame body is fixedly provided with a connecting plate, a nut is fixed on the inner side of the connecting plate, a through hole is formed in the connecting plate opposite to a threaded hole of the nut, and the end connecting piece is connected with the nut through a screw.

Wherein, support body, hypoplastron, fin, lower radiating portion all pass through the section bar integrated into one piece.

In conclusion, the LED lamp tube convenient for heat dissipation has the advantages of enabling heat to flow rapidly, prolonging service life better, and being simple and stable.
