new lamp shade

Abstract

The invention relates to a novel lampshade of a vehicle headlamp, which can effectively balance a temperature difference between inside and outside of a headlamp and effectively prevent fog and a heating deformation situation of parts. The novel lampshade of the vehicle headlamp comprises a hemispherical lampshade body and a back plate fixed on the back side of the lampshade body, wherein an air inlet is formed in the front side of the bottom of the lampshade body; an upwards bent flow baffle is arranged on the inner side of the air inlet; a filtering screen is arranged at the air inlet; a water filtering screen is arranged between the end part of the flow baffle and the lampshade body; a drying agent is arranged between the filtering screen and the water filtering screen in a filling manner; a first air outlet and a second air outlet are respectively formed in the top and the bottom of the rear side of the lampshade body; a temperature control switch is arranged on the top of the inner side of the lampshade body; a sliding cover plate and a motor are arranged at the bottom of the lampshade body; the sliding cover plate relatively slides on the outer side of the air inlet under the driving of the motor; the temperature control switch is electrically connected with the motor.

Description

technical field [0001] The invention relates to a spare part of an automobile lamp, in particular to a novel lamp shade of an automobile lamp. Background technique [0002] With the rapid development of the automobile industry, while people are pursuing comfort and ease of handling, more and more attention has been paid to the overall safety, energy saving and environmental protection of automobiles. In this regard, the headlights of automobiles now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; The airtight form is buckled on the headlight. When the headlight is in the lighting state, the airtight environment it is in will generate a higher temperature due to heat accumulation. This higher temperature is not only easy to burn in the car. Fog is generated inside the lamp, which affects the lighting effect, and it is easy to cause the parts in the car lights to be deformed by heat...

In this regard, the headlights of automobiles now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; The airtight form is buckled on the headlight. When the headlight is in the lighting state, the airtight environment it is in will generate a higher temperature due to heat accumulation. This higher temperature is not only easy to burn in the car. Fog is generated inside the lamp, which affects the lighting effect, and it is easy to cause the parts in the car lamp to be heated and deformed, and even the parts are melted.
