Description

Technical Field

[0001] The utility model belongs to the field of floor lamps, and particularly relates to an annular light-emitting structure with good heat dissipation and a floor lamp. Background Technique

[0002] A floor lamp usually consists of three parts: a lampshade, a lamp post, and a base. Among them, the lampshade is used to block and reflect light, the lamp post is used to support and adjust the height, and the base is used to fix and maintain balance. The floor lamp not only provides light for the indoor environment but also has a certain decorative effect. Its unique shape and design can become the highlight of the indoor space and create a unique atmosphere. Floor lamps are widely used in places such as homes, hotels, and cafes. In the home environment, floor lamps are often used in spaces such as the living room and bedroom to provide auxiliary lighting and create an atmosphere. In commercial places such as hotels and cafes, floor lamps are more used for decoration and creating an atmosphere to enhance the style and quality of the overall space. The main purpose of the light-emitting structure of the floor lamp is to provide local lighting and play a role in decorating the space. The design of the light-emitting structure needs to consider the distribution of light, softness, and the aesthetic appearance of the lamp. The main purpose of the heat dissipation structure is to ensure that the floor lamp can maintain a stable temperature during use, avoiding potential safety hazards and performance degradation caused by overheating. In the existing light-emitting and heat dissipation structures of floor lamps, generally, a lamp board is directly set on the heat dissipation plate, which will cause a small light-emitting surface and uneven light when emitting light upward. At the same time, the setting of the lamp board will also affect the heat dissipation effect.

[0003] Chinese Patent No. CN 207486543U discloses an LED floor lamp, which makes the light more uniform and does not irritate the human eye by setting the LED lamp board on the side of the light guide plate, but does not involve the problem of ensuring both the heat dissipation effect and the light-emitting effect at the same time.

[0004] Therefore, aiming at the problems existing in the prior art, there is an urgent need to provide an annular light-emitting structure with good heat dissipation and a floor lamp to solve the problems existing in the prior art. Summary of the Invention
