Description

[Technical field]

[0002] The utility model relates to the field of lighting, in particular to a small-pitch white light strip LED bracket. [Background technology]

[0004] As the demand for LED light strips rises sharply, consumers and the industry have higher expectations for the quality of light strip products. Among them, the demand for optimizing the aperture of lamp beads is particularly prominent. The LED light strip brackets currently on the market generally have problems such as large single bead size and wide spacing of lamp beads, which directly leads to significant spot effects during lighting, clear and discernible aperture boundaries, and affects the uniformity and aesthetics of lighting. In actual applications, when light strips are bent or twisted to adapt to complex installation environments, the larger lamp bead spacing and inflexible structural design can easily cause damage to the lamp beads, which not only shortens the product's service life, but also limits its potential in creative installations and special scene applications.

[0005] Therefore, there is an urgent need to provide a small-pitch white light strip LED bracket to solve the above-mentioned technical problems existing in the prior art. [Contents of the utility model]
