Problems solved by technology

The first method has limited improvement in heat dissipation. The second method increases the power consumption of fluorescent tubes and has high manufacturing costs. In addition, the possibility of failure during use increases. Although the third method solves the heat dissipation problem better, However, no effective improvement has been made to the propagation quality of light integrated with LED illuminants
Another kind of LED lamp tube adopts the heat-dissipating and heat-transfer aluminum profile to be built into the inner wall of the glass cover tube along the axial direction, so that the LED luminous body directly fits closely with the aluminum

Abstract

The invention relates to an LED (Light-Emitting Diode) lamp tube with large light flux and a large light-emitting angle. The LED lamp tube is provided with an insulated connecting sleeve which introduces a power supply to the electricity supply part of a COMMB-LED light source assembly and the heat dissipating and transferring aluminum profile support frame part of a V-shaped structure; the combined body of the heat dissipating and transferring aluminum profile of the V-shaped structure and the COMMB-LED light source assembly is arranged in a glass lamp tube. The LED lamp tube is characterized in that the heat conducting and transferring aluminum profile of the V-shaped structure is arranged in the glass lamp tube of the LED lamp tube along the length direction of the lamp tube; the COMMB-LED light source assembly is arranged on two symmetrical inclined surfaces of the heat conducting and transferring aluminum profile of the V-shaped structure and closely contact with the heat conducting and transferring aluminum profile in an adhering way; both ends of the lamp tube is provided with constant current power supplies; a diffusion membrane or a fluorescent powder adhesive tape which realizes light uniformity, different color temperature and color developing indexes is arranged on the inner wall of the glass tube positioned in the light-emitting direction of the COMMB-LED light source assembly.

Description

technical field [0001] The invention relates to an LED lamp tube with an LED as a luminous body, in particular to an LED lamp tube with a large luminous flux and a large light output angle using a COMMB-LED light source assembly as a light source. Background technique [0002] The current LED lamp tubes mostly use heat-conducting glue to stick a single LED lamp bead as a light-emitting body to the supporting plane of the heat-dissipating aluminum profile. The aluminum profile is seamlessly buckled with the PC cover, and the light-emitting body is mostly made of PCB. The printed circuit on the board is used as the circuit connection board of the independent lamp bead, and the white light-emitting LED is connected in series through the printed circuit on the PCB board to form a low-voltage module and then connected to the constant current power supply controller. As far as the existing LED light tubes are concerned, whether the illuminant uses a rectangular electrode in-line l...
