Description

Technical Field

[0001] This utility model belongs to the field of lighting fixture technology, specifically, it relates to a television background light. Background Technology

[0002] As people's living standards continue to improve, television, as a core device for home entertainment, is experiencing increasingly diverse usage scenarios and experiential demands. When watching television, traditional, monotonous indoor lighting often fails to meet users' demands for atmosphere and visual comfort. On the one hand, excessively bright or dim ambient light can affect the contrast and color performance of the television picture, leading to eye strain; on the other hand, lighting lacking depth and variation cannot effectively complement the television content, reducing the immersive viewing experience.

[0003] Utility model CN211118894U discloses a TV background light mounting structure, including a base strip, clips, and an LED light strip. The base strip is arranged in a circle and fixed to the back of the TV by the clips, with the base strip perpendicular to the back of the TV. The LED light strip is attached to the outer surface of the base strip with double-sided adhesive, so that the LED beads on the LED light strip point to the outer perimeter of the back of the TV. This utility model's TV background light mounting structure greatly improves the luminous utilization rate of the LED light strip, enhances the lighting effect, and is easy to assemble and inexpensive.

[0004] However, the aforementioned patents still have the following problems: After prolonged use, the temperature of the TV back cover rises, affecting the adhesion of the double-sided adhesive, causing the LED strip to fall off due to poor adhesion, thus affecting the display effect of the LED strip. The connection structure between the LED strip and the TV back panel needs improvement, resulting in poor display effect of the LED strip. The design shape and structure of some TV back panels are relatively complex, with some protrusions, depressions, or irregular parts. These structures can block the light, affecting the display effect of the LED strip, and making the device inconvenient to use.

[0005] In view of this, this utility model is proposed. Utility Model Content
