Vibration-absorbing base of lamp and floodlight adopting the vibration-damping base

Abstract

The invention discloses a damping base for a lamp. The damping base comprises a carrying seat, an elastic seat, a movable support rod, a bulb mounting seat provided with a spherical groove, and a plurality of pull rods with elastically-adjustable lengths, wherein the carrying seat comprises a fixing plate and a guide column which is vertical to the fixing plate; the elastic seat comprises an elastic part, an upper mounting plate and a lower mounting plate; the two ends of the elastic part are fixedly connected with the upper mounting plate and the lower mounting plate respectively; both the upper mounting plate and the lower mounting plate are correspondingly provided with through holes; the guide column passes through the through hole of the upper mounting plate; one end of the movable support rod passes through the through hole of the lower mounting plate, and is in sliding sleeve connection with the free end of the guide column; a bulb is arranged at the other end of the movable support rod; the bulb is arranged in the spherical groove, and can rotate freely in the spherical groove; the two ends of each pull rod are rotationally connected with the middle part of the movable support rod and the bulb mounting seat respectively. The damping base has the advantages of achieving a good damping effect, prolonging the light source service life of the lamp and reducing the maintenance cost of the lamp. The invention further provides a projection lamp adopting the damping base.

Description

【Technical field】 [0001] The invention relates to a vibration-damping structure of a lamp, in particular to a vibration-damping base of a lamp and a projection lamp using the vibration-damping base. 【Background technique】 [0002] The mounting bases of existing lamps generally do not have an anti-vibration design, and are easily affected by external vibrations in places with strong vibrations. Under the action of vibration, it is easy to loosen the structural parts inside the lamp, resulting in failure of the internal structural connection. At the same time, external vibration also has a negative impact on the light source inside the lamp body. When the vibration is easy to cause the light source to sway and shake, the light source will be out of contact with the lamp holder and the lamp will go out. In severe cases, the bulb shell of the light source will be broken, reducing the use of the light source. life. 【Content of invention】 [0003] In view of the above situatio...

[0002] The mounting base of the existing lamps generally does not have an anti-vibration design, and is easily affected by external vibrations in places with strong vibrations

Under the action of vibration, it is easy to loosen the structural parts inside the lamp, resulting in failure of the internal structural connection

At the same time, external vibration also has a negative impact on the light source inside the lamp body. When the vibration is easy to cause the light source to sway and shake, the light source will be out of contact with the lamp holder and the lamp will go out. In severe cases, the bulb shell of the light source will be broken, reducing the use of the light source. life
