Abstract

The invention provides a lamp demisting structure which comprises a lamp body (10) and a demisting pipeline (20), wherein the lamp body (10) comprises a lamp housing (11); the lamp housing is providedwith at least one opening used for feeding and discharging; the opening of the lamp housing is provided with a sealing element which is sealed relative to external environment; a material opening ofthe demisting pipeline (20) is connected with the opening of the lamp housing (11); drying agents (30) are put inside the demisting pipeline; and ventilation holes (21) are formed in the demisting pipeline, so that the moisture absorption function of the drying agents in the demisting pipeline can be realized through the ventilation holes. Meanwhile, the invention also provides motor vehicle illuminating equipment with the lamp demisting structure. The problems caused by a mist condensation phenomenon in the lamp can be relieved and/or solved.

Description

technical field [0001] The invention relates to the field of light illumination and signal indication, in particular to a lamp defogging structure and a motor vehicle lighting device having the aforementioned lamp defogging structure. Background technique [0002] In the field of motor vehicle lighting equipment, after use of light-emitting components, condensation will inevitably occur, especially when the humidity inside the lamp is high. The fog condensation phenomenon will affect the use effect of the lamps and even cause the lamps to fail. [0003] In order to solve this problem, some of the existing lamps and lanterns are designed to prolong the condensation time of the luminous parts after use to alleviate the condensation phenomenon; Fog speed, in order to eliminate the adverse effects of condensation phenomenon; there are some ways to solve the fog condensation problem by coating the anti-fog layer in the lamp, but the disadvantage of this method is that the servic...
