The patent abstract shows that this utility model relates to the field of transportation protection technology for bulb lamps, specifically a bulb lamp structure comprising a lamp head with a light source, a transition cover connected to the lamp head, a spherical lampshade connected to the bottom of the transition cover, and an anti fall mechanism on the transition cover that can prevent the lamp head and the spherical lampshade from falling and injuring; The anti fall mechanism includes anti fall components and balance components. The anti fall components are installed on the transition cover and lamp head to prevent damage to the lamp head and transition cover. The balance components are installed on the transition cover to trigger the anti fall components when the lamp head contacts the ground. This utility model can protect the lamp in case of accidental dropping. The weight of the fixed ball side is much greater than that of the moving ball side, so that when the lamp falls, the heavier side of the protective frame can drive the lamp to rotate at a certain angle, so that the lamp head part will contact the ground before the spherical lampshade part. At this time, the protective airbag and protective sleeve will buffer the contact with the ground to avoid damage and breakage of the spherical lampshade in contact with the ground.
