TWM425477U - LED lamp - Google Patents

Abstract

A LED lamp includes a heat transfer tube, an end cap, a PCB, a plurality of LED, an insulating element, and an AC/DC converter. The heat transfer tube has a containing room, and the end cap is disposed on the end of the heat transfer tube. The PCB is disposed on the heat transfer tube and the AC/DC converter is disposed in the containing room. The output terminal of the AC/DC converter is disposed on the PCB to provide power to the LED on the PCB. The insulating element is disposed on one end of the heat transfer tube and combined with the end cap. The insulating element includes an insulating plate and an extending portion. The insulating plate has a through hole. The AC/DC converter has an inputting conductive line which is passed through the through hole and electrically connected with conductive bars of the end cap. The insulating plate is disposed between the AC/DC converter and the conductive bars, in order to insulate the AC/DC converter and the conductive bars on the end cap.

Description

M425477 V. New description: [New technical field] The present invention relates to a tubular lamp, and in particular to an LED lamp. [Prior Art] Light emitting diodes (LEDs) have the characteristics of low energy consumption, long service life, small size, and fast response. In recent years, the development of their technology has become increasingly mature, so it has gradually The replacement of traditional lamps, especially the application of LEDs in the most used fluorescent tubes, namely · LED tubes, is currently the mainstream topic in the industry. At present, the LED tube on the market generally includes a circuit board and a plurality of LEDs, and these LEDs are disposed on one surface of the circuit board. In order to remove the heat generated by the LED, a semi-cylindrical heat pipe body is formed on the other surface of the circuit board, and the heat pipe body is made of aluminum. By dissipating the heat pipe body, the waste heat generated by the LED can be eliminated. Since the heat-dissipating tube body is made of aluminum or other metals with high thermal conductivity, and these metals with thermal conductivity often have good electrical conductivity, it may cause leakage and cause the user to install. There are safety concerns when using LED lamps. The reason why leakage occurs is mainly because when current flows inside the LED tube, current may be conducted to the heat sink body due to poor design of the electrical insulation. In order to avoid leakage, some LED manufacturers will set the AC-DC converter outside the LED tube, but this will require additional space on the lamp holder to accommodate the AC-DC converter, but this will result in LED tube is inconvenient to install. Therefore, how to make the LED tube design meet the safety specifications, and at the same time, it is not inconvenient for the user to install the LED tube, it is worthy of the field.
