Lamp

Abstract

The invention relates to a lamp comprising a lamp body and a vibration damper connected with the lamp body. The vibration damper comprises a first installation board, a second installation board, a connecting rod, a spring, a first vibration absorbing sleeve and a second vibration absorbing sleeve, wherein the spring is clamped between the first installation board and the second installation board; a first sleeve barrel for containing the first vibration absorbing sleeve is formed by extending on the first installation board, and a second sleeve barrel for containing the second vibration absorbing sleeve is formed by extending on the second installation board; the connecting rod is provided with opposite first end and second end, the first end of the connecting rod protrudes the first sleeve barrel and limits the first vibration absorbing sleeve in the first sleeve barrel, and the second end of the connecting rod protrudes the second sleeve barrel and limits the second vibration absorbing sleeve in the second sleeve barrel. The lamp has the advantages of better vibration damping performance 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...

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 there is severe vibration without direction, the lateral swing of the lamp is difficult to control, and the lamp is also vulnerable to damage at this time. Even if the lamp is not destroyed immediately, the direction of the light source is changing, which also affects the lighting effect, that is, the vibration reduction effect is lacking
