1. A telescopic lamp, comprising:
a lamp handle (1);
a first support (2), having a first light-emitting member (3) disposed thereon;
a second support (4), extending in the same direction as the first support (2), slidably connected to the first support (2) along a length direction of the first support (2), and having a second light-emitting member (5) mounted thereon;
wherein, the second light-emitting member (5) and the first light-emitting member (3) extend in the same direction and are arranged to be non-coplanar;
during a process of relative sliding of the second support (4) and the first support (2), the second support (4) has a contracted state, in which the second support (4) is stacked on the first support (2), so as to cause the second light-emitting member (5) to be stacked on the first light-emitting member (3), and has an extended state, in which the second support (4) extends outwards relative to the first support (2), so as to cause the second light-emitting member (5) and the second light-emitting member (5) to be arranged in sequence along a length direction of the first support (2);
a locking mechanism is arranged between the first support (2) and the second support (4) to lock the second support (4) in the contracted state or the extended state; and
a light-emitting surface of the first light-emitting element (3) and a light-emitting surface of the second light-emitting element (5) are located on the same side surface of the lamp.
