LED (light emitting diode) tubular lamp structure with high technological performance

Abstract

The invention provides an LED (light emitting diode) tubular lamp structure with high technological performance. The LED tubular lamp structure comprises a lamp panel, a lamp panel rack and a power supply, wherein a rectification IC (integrated circuit) in the power supply is arranged at one end of the lamp panel; a constant current circuit in the power supply is arranged at the other end of the lamp panel; a bulb is arranged between the rectification IC and the constant current circuit; the rectification IC and the bulb are welded to the lamp panel and are distributed along the length direction of the lamp panel rack; a non-welding surface of the lamp panel is in heat-conduction connection with a plane of the lamp panel rack; a first alternating current bonding wire pad is arranged at an alternating current inputting end of the rectification IC and is close to a first lamp holder; the first alternating current bonding wire pad is electrically connected with a wiring end of the first lamp holder; another alternating current inputting end of the rectification IC extends to a second alternating current bonding wire pad through a wire; the second alternating current bonding wire pad is arranged at the other end of the lamp panel, is close to a second lamp holder and is electrically connected with a wiring end of the second lamp holder; a positive outputting end of the rectification IC is electrically connected with one end of the LED bulb; the other end of the LED bulb of the lamp panel is electrically connected with a positive inputting end of the constant current circuit; and a negative outputting end of the constant current circuit is electrically connected with a negative outputting end of the rectification IC. The LED tubular lamp structure with the high technological performance is high in designability and high in reliability.

Description

technical field [0001] The invention relates to an LED tube lamp, in particular to an 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 two wires at...

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.
