Lamp

Abstract

A lamp capable of insolating vibrations for light source comprises a lamp housing, a reflective cup fixedly connected with the lamp housing, and the light source arranged in the reflective cup, wherein a lamp holder is arranged in a housing formed by the lamp housing and the reflective cup in the axial direction of the reflective cup; the light source is fixedly connected with the lamp holder; the lamp holder is connected with the lamp housing through an elastic element; the elastic element applies elastic forces towards the lamp housing direction on the lamp holder; and a support piece used for supporting the light source is fixedly arranged in the reflective cup. According to the lamp, when the lamp is subjected to external vibration shock, the lamp housing and the reflective cup can vibrate therewith, as the elastic element applies the elastic force towards the lamp housing direction on the lamp holder, so as to allow the light source connected with the lamp holder to be closely contacted with the support piece, and therefore, the light source and the lamp holder can vibrate together with the lamp housing and the reflective cup; and in the process of vibration, as the support piece supports the light source all the time, the light source can not shake relative to the lamp holder along with the vibration of the lamp, so as to allow the vibration resistance of the light source to be increased, and avoid happening of the phenomenon that the light source is shattered.

Description

technical field [0001] The invention belongs to the field of lamps, in particular to a lamp capable of reducing the vibration of a light source. Background technique [0002] At present, when common lighting fixtures are installed, the light source is usually screwed and fixed to the lamp holder through its metal input end, and the lamp holder is then fixed into the lamp housing. Although this installation method is simple, there is the problem that the vibration resistance of the light source is not strong after the light source is fixed, especially when the high-power lighting source is installed in a cantilever type, it is easy to be cracked by vibration. The metal input end is screwed onto the lamp holder through threads, and the other end is not effectively fixed. The entire weight of the light source falls on the joint between the metal input end and the lamp holder. In strong vibration situations, the light source will swing with the external vibration. , causing the...
