U-shaped LED fluorescent lamp

Abstract

Provided is a U-shaped LED fluorescent lamp. A rear-end supporting frame of the U-shaped LED fluorescent lamp comprises a first U-shaped piece and a second U-shaped piece matched with the first U-shaped piece. The first U-shaped piece comprises first installation parts matched with the ends of two straight tubes respectively and a first connecting part connected with the first installation parts, and first positioning columns are arranged at the connecting positions of the first installation parts and the first connecting part. An LED lamp panel is an internally-formed flexible substrate and comprises two light-emitting sections and a middle connecting section used for connecting the two light-emitting sections. The middle connecting section of the LED lamp panel is fixed in a turning mode through the first positioning columns. The U-shaped LED fluorescent lamp has the advantages that the flexible substrate is adopted as the LED lamp panel and has certain flexibility, so that adaptability is better; besides, the flexible substrate has a better cooling effect compared with a hard substrate, and it is unnecessary to independently install metal cooling fins, so that the cost of a lamp tube is low; the first positioning columns on the first U-shaped part provide turning positioning fulcrums for the LED lamp panel, so that positioning and installation of the LED lamp panel are facilitated, and it is avoided that the LED lamp panel is excessively turned and torn.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201610152885.6 and the title of the invention "A U-shaped LED fluorescent lamp" submitted to the China Patent Office on March 17, 2016, the entire contents of which are incorporated in this application by reference. technical field [0002] The invention relates to a lamp, in particular to a U-shaped LED fluorescent lamp. Background technique [0003] LED fluorescent lamps have many advantages such as long service life, small size, energy saving and power saving, so they are widely used in the market and gradually replace the existing incandescent lamps. [0004] Depending on the specific application environment, sometimes the overall LED fluorescent lamp needs to be designed as a U-shaped structure. The existing U-shaped LED fluorescent lamp is difficult to bend because the lamp board is made of a hard PCB board. Luminous rigid boards or wires transition to connect the ...

AI Technical Summary

Problems solved by technology

Such a setting has the problem that excessive part of the light will affect the luminous effect of the lamp tube. At the same time, due to the poor heat dissipation effect of the hard board, a heat sink structure is generally added outside the lamp tube, which greatly increases the cost of the lamp tube.

In addition, due to the lack of proper positioning and guiding structures, the hard light boards or wires in the transitional part are easy to shake or break, which affects the working efficiency of the light.
