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...

AI Technical Summary

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 profile in the same plane, so that the heat on the mirror aluminum plate is quickly transferred to the heat-dissipating heat transfer tube. On the hot aluminum profile, the aluminum profile and the glass cover are seamed and made. Because the heat transfer and light transmission of the glass cover are higher than that of the PC cover, the temperature field in the closed space formed by the LED as the illuminant and the glass cover is uniform. , so that the node temperature of the LED chip has been greatly improved, but the light output angle is still less than 120°C, so the above-mentioned LED fluorescent lamp tubes have defects and need to be improved
