Abstract

The invention relates to a projection lamp provided with a vibration damper, comprising a projection lamp box, a bulb accommodated in the projection lamp box and a transparent lampshade arranged at the front end of the projection lamp box, wherein a lamp holder used for accommodating the bulb and a lamp holder sleeve used for accommodating the lamp holder are arranged in the projection lamp box, and the projection lamp also comprises the vibration damper which is elastically contacted with the end part of the bulb. The projection lamp avoids bulb breakage during vibrating or thrashing, improves the using reliability in the severe environment, prolongs the service life of the bulb and reduces the maintenance cost of the projection lamp.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a durable projection lamp in a vibrating environment. Background technique [0002] Projector lights are widely used in mining, cargo docks, motor vehicles and shipping fields due to their strong light brightness and long projection distance. The working environment in these fields often has strong vibration or bumps. In this way, when the projection lamp works in such a harsh environment, its bulb will often be broken due to excessive vibration intensity. Therefore, it is necessary to invent a projection lamp that can be safely used in harsh environments such as vibration or bumps. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a projection lamp with a vibration damping device, so as to avoid the problem that the bulb of the projection lamp is easily broken in a vibrating environment. [0004] The technical solution ad...
