The invention discloses a lamp dimming structure and application thereof, relates to the technical field of automobile parts, and solves the problem that a lamp is burst and damaged when the lamp dimming structure is used improperly in the prior art. Comprising a lamp shell, a dimming rod and a support assembly. Wherein the support assembly is fixed to the lamp, the dimming rod comprises a base and a rod body, the diameter of the rod body is gradually changed, the rod body comprises a thread-free section and a thread section, the thread-free section comprises a polished rod and a polished shaft, the rod body is arranged in a mold opening of the lamp shell in a penetrating mode, the base abuts against the outer edge of the lamp shell, and the support assembly is in threaded connection with the thread section. The bracket assembly moves back and forth on the thread section by rotating the dimming rod, so that the lamp displaces, and the dimming effect is achieved; and the arranged polished rod can limit the bracket assembly to form upper dead point and lower dead point protection, so that the bracket assembly is prevented from moving to exceed the stress-strain value of the lamp, and the lamp is prevented from bursting.
本发明公开了灯具调光结构及其应用,涉及汽车零部件技术领域,解决了现有技术使用不当时会导致灯具爆裂受损的问题。包括灯壳、调光杆和支架组件;其中,支架组件固定在灯具上,调光杆包括底座和杆体,杆体为渐变直径,杆体包括无螺牙段和螺牙段,无螺牙段包括光杆和光轴,杆体穿设于灯壳的开模口内,底座与灯壳外缘相抵接,支架组件与螺牙段螺接。本发明通过转动调光杆使支架组件在螺牙段上来回移动,从而使灯具发生位移,实现了调光效果;并且设置的光杆能够对支架组件进行限位、形成上死点及下死点保护,避免支架组件移动至超过该灯具的应力应变值,防止灯具爆裂。
