Problems solved by technology

[0004] However, this light fixture still has disadvantages. Although the steel cable will not stretch basically, the lateral swing range can be very large. Even if the spring is used, it can only be improved to a limited extent, because usually the lateral swing range of the spring is also quite large. Therefore, when subjected to When

Abstract

The invention relates to a lamp which comprises a lamp body and a damping device connected with the lamp body, wherein the damping device comprises a first mounting plate, a second mounting plate, a connecting rod, a first spring and a second spring; the first mounting plate and the second mounting plate are mutually parallel; the connecting rod is provided with a first end part and a second end part which are opposite; the second end part is penetrated into the first mounting plate and fixed on the second mounting plate; the first spring is clamped between the first mounting plate and the first end part of the connecting rod; the second spring is clamped between the first mounting plate and the second mounting plate and sleeved on the connecting rod; the first mounting plate extends along the axial line direction of the connecting rod to form a first sleeve; and the first spring is at least partially accommodated in the first sleeve. By adopting the structure, the lamp has better damping property and longer service life.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp with a damping device. Background technique [0002] In the field of professional lighting, professional lamps are often subjected to continuous and strong vibration excitation, which makes light bulbs, electronic ballasts and other structures with poor vibration resistance easy to fall off, break and other damage, which affects the normal use of lamps and brings many problems to users. trouble and loss. [0003] An existing lamp is composed of a lampshade, a lamp base, a steel cable and a ceiling plate. The steel cable is connected to the lamp base and the ceiling plate, and a spring is used to wrap around the steel cable. The two ends of the spring are connected to the lamp base and the ceiling respectively. plate. It reduces the impact force transmitted from the ceiling plate to the lamp base by changing the general rigid suspension rod into a flexible steel cable, and uses the spring to all...
