Vibration isolator module, combined vibration isolator and vibration isolation lamps

Abstract

A vibration isolation sub-module, a combined vibration isolator and a vibration isolation lamp. When the vibration isolation lamp is a light lamp, it includes a lamp holder, a bracket and a vibration isolation sub-module installed under the bracket. When the vibration isolation lamp is a medium-sized lamp, its It includes a lamp holder, a bracket and a combined vibration isolator installed under the bracket. The vibration isolation sub-module includes: a top plate, a bottom plate and a damping part. The top plate is made of metal; the bottom plate is made of metal; the damping part is made of rubber. Between the top plate and the bottom plate, a through hole is provided in the center of the cross-section of the damping member along the height direction, and the two side walls of the damping member are symmetrical, and the side walls include two splicing surfaces with an included angle of 120 degrees connected successively in the height direction Or three splicing surfaces with an included angle of 135 degrees. The vibration isolation sub-module and the combined vibration isolator can be applied to various lamps with different loads to improve the vibration resistance of the lamps.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a vibration isolation structure of a lighting fixture used in the field of military vehicles and ships. Background technique [0002] Lighting lamp brackets installed in the environment of various military mobile vehicles generally need to be able to withstand the vibration in the environment and have strong structural rigidity. Generally, the typical shock and vibration spectrum of high-intensity vibration and shock environment lamps (including military industry requirements) is 10 Hz to 1000 Hz, while military combat vehicles and naval ship environment lamps must withstand more stringent requirements. It even reaches 150G ~ 300G, and at the same time must meet the low frequency response below 2Hz in ballistic experiments such as shelling. However, optical components such as light sources and lenses of general lamps or other optical equipment are relatively fragile, especially when directl...

AI Technical Summary

Problems solved by technology

[0006] To sum up, in the field of professional lighting, medium and large-scale professional lamps are subject to continuous and strong vibration excitation, and generally three-way vibration. However, as mentioned above, the existing vibration isolators for large and medium-sized lamps cannot meet this requirement Therefore, large and medium-sized professional lamps urgently need a three-way vibration isolator to completely isolate the lamp from the excitation vibration source, and improve the long-distance quasi-light projection angle and service life of the lamp
