Abstract
The invention relates to a projection lamp with a damping device, aiming to solve the problem that a bulb is broken when the projection lamp is used in a strong shocking environment because no dampingdevice is arranged in the projection lamp. The projection lamp with a damping device comprises a lamp housing, a lamp holder arranged in the lamp housing and the bulb arranged on the lamp holder, whe rein the lamp housing comprises a lamp case and a transparent lamp cover arranged on the opening end of the lamp case, the lamp housing is internally provided with the damping device, and the damping device comprises an elastic component which elastically contacts the front end of the bulb and supporting legs which fix the elastic component on the lamp housing. The projection lamp damps the impactforce of the bulb in the shocking or jolting process by elastically supporting the front end of the bulb by the damping device so as to prevent the bulb from being broken and prolong the service life of the bulb.
