Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, in particular to a linear lamp structure with a symmetric lens. Background Technique

[0002] An LED strip refers to assembling LEDs on a strip-shaped FPC (flexible printed circuit board) or PCB hard board, and it gets its name because its product shape is like a strip. Because of its long service life (generally the normal life is 80,000 - 100,000 hours), and it is very energy-saving and environmentally friendly, it has gradually emerged in various decoration industries.

[0003] When the existing LED linear lamps are in use, in order to make the emitted light brighter and more uniform, a circular lens is generally installed in the LED linear lamp fixture. However, such lamp strips will have the following problems when in use: 1. The circular lens may affect the optical efficiency of the LED lamp. Due to its shape limitation, part of the light energy may be lost when the light passes through the circular lens, resulting in a lighting effect that is not as expected; 2. The circular lens may not effectively constrain the light direction, which means the light may scatter irregularly, resulting in a poor lighting effect; 3. When installing such a lamp strip in the lamp housing structure, multiple screws are usually used to fix the position of the lamp strip structure, and the installation and disassembly are relatively cumbersome and inconvenient to use.

[0004] Therefore, a linear lamp structure with a symmetric lens is needed to improve the above problems. Content of the Utility Model
