What are the differences between zoomable led track light bulbs and other types of bulbs?

A zoomable led track light bulbs, the bulb comprises a lamp body and a lamp cover, the sides of the lamp shell of the lamp body are recessed inward to form a plurality of strip-shaped chutes; the lamp cover comprises a sliding ring and a lamp shade, and the sliding ring and the lamp shade are fixedly connected And the two are connected, the inner side of the sliding ring protrudes inwardly with a plurality of strip-shaped buckles that are adapted to the corresponding sliding grooves, and the telescopic structure of the bulb is formed by the matching and sliding of each buckle and the corresponding sliding grooves. , After each clip is completely slid into the corresponding chute, the lamp shell shrinks into the lampshade, and after each clip slides out of the corresponding chute, the lamp shell extends in the lampshade. This product is realized by the above-mentioned telescopic structure The lamp housing shrinks or extends in the lamp face. The improvement of the above structure of this product, through the telescopic design, can reduce the volume of the bulb, thereby reducing the packaging and transportation cost of the bulb.
