High-power LED lamp structure with good manufacturability

Abstract

The invention discloses a high-power LED lamp structure with good manufacturability. The high-power LED lamp structure with good manufacturability comprises a lamp panel, a lamp panel frame and a power source, wherein a rectification IC in the power source is arranged at one end of the lamp panel, a constant current circuit in the power source is arranged at the other end of the lamp panel, and lamp beads are arranged between the rectification IC and the constant current circuit; the rectification IC and the lamp beads are welded on the lamp panel, and are distributed in the length direction of the lamp panel frame; the non-welding surface of the lamp panel and the plane surface of the lamp panel frame are in heat conduction connection; a first alternating-current welding wire coil is arranged at one alternating-current input end of the rectification IC and an adjacent first lamp holder, and is electrically connected with the wiring end of the first lamp holder; a wire penetrates through the lamp panel, and extends from the other alternating-current input end of the rectification IC to a second alternating-current welding wire coil arranged on the portion, close to a second lamp holder, of the other end of the lamp panel, and the second alternating-current welding wire coil is electrically connected with the wiring end of the second lamp holder; the positive output end of the rectification IC is electrically connected with one end of each LED lamp bead of the lamp panel, the other end of each LED lamp bead of the lamp panel is electrically connected with the positive input end of the constant current circuit, and the negative output end of the constant current circuit is electrically connected with the negative output end of the rectification IC. The high-power LED lamp structure is good in structural performance and high in reliability.

Description

technical field [0001] The invention relates to an LED tube lamp, in particular to a high-power LED tube lamp structure with good manufacturability. Background technique [0002] Such as figure 1 As shown, the structure of the existing LED tube lamp is given; including the lamp board and the lamp board frame, the lamp board frame is a semi-cylindrical aluminum alloy frame, the semi-circular plane fixes the lamp board, and the semi-cylindrical cavity fixes the power supply; the power supply includes at least four lines, Two of them are connected to 220v power supply as the input terminal of AC power supply, and two of them are used as DC voltage terminals to supply the DC voltage of the LED light board. When installing, the two wires of the power supply in the semi-cylindrical shape are drawn from the left end of the semi-cylindrical cylinder to the left end, and the other two wires are drawn from the right end of the semi-cylindrical cylinder to the right end. One of the tw...

Problems solved by technology

[0003] It can be seen from the above structure that at least four wires pass through the semi-cylinder, and the power supply cannot be effectively fixed. The threading process is time-consuming, affects work efficiency, and affects reliability. It is mainly reflected in the inevitable shock or vibration during transportation, which may dislocate the lead wires.
